Description

Method for connecting a base body to a component and device for carrying out the method

In many industries, the task is repeatedly asked to connect a body with a component. In the automotive field, e.g. To connect a base body in the form of a windscreen with a component which should have certain properties or in turn should fulfill certain tasks, such as to accommodate another part.

Among various examples is one in which the body of the front window of a car is present, on the lower edge of which a connection strip is to be fastened to which a water box is to be subsequently attached, namely to be suspended or clipped on.

This terminal block has a metal frame, whose free-standing longitudinal edge has a latching edge has the cross-sectional profile of a spring lug on which a matched profile section of the water box can be engaged. The other longitudinal edge of the metal frame is formed as a connecting edge comb-like, wherein the

Tines are alternately straight and angled. In addition to the metal frame, a plastic body is provided, which serves as a spacer and as a positioning element between the metal frame and the glass sheet. The plastic body has an approximately L-shaped cross-section and bears against the outer edge of the glass pane and on the adjacent pane surface. At this the plastic body is attached by means of a double-sided adhesive tape. In the vicinity of its latching edge, the metal framework is attached by means of a double-sided adhesive tape to the upper side of the plastic body. The metal framework protrudes with its connecting edge beyond the edge of the plastic body. This protruding region of the width extension of the metal framework and its section adjacent to the latching edge are referred to as the connection region of the component. On the glass sheet as the base body that portion of its disk surface, which adjoins the edge of the plastic body and extends beyond the ground plan area of the metal frame, is referred to as the connection region of the base body. On these two connection areas, a hardening potting compound is applied as a bonding compound which, after curing, permanently bonds the base body and the component together.

The bonding compound is cast loose along the component on the two connection areas. This can be done by hand. Usually, however, a robot is used for this purpose. Due to the fact that the compound compound is, on the one hand, poured freely and, on the other hand, solidifies in a very short time, the surface of the cast-on strand of the bonding compound is relatively uneven. In addition, this entails the risk that the bonding compound does not completely penetrate into all cavities of the comb-like connection edge of the metal framework. As a result, the strength of the connection between the base body and component is reduced.

The invention has for its object to perform the method for connecting a body with a component so that the strength of the compound is higher than in the known method and the joint has a pleasing appearance. This object is achieved by a method having the method steps specified in claim 1. Characterized in that on the base body and the component, a molded part is placed, which projects beyond the connection region of the base body and the component, which has a matched to the connection region of the base body and the component recess for a curing bonding compound, which after curing the main body and the Connects component with each other and whose on the base body and the component outside the connection areas fitting surface areas are matched to these two parts, the recess for the connection region of the base body and the component can be hermetically sealed to the outside. Because the molded part is made of a flexible material and a pressing force is exerted on its side facing away from the base body and the component at least in sections, the hermetic seal of the molded part can be maintained in its recess with respect to the base body and the component even with an overpressure , As a result, in turn, the curing compound in the recess of the molding with

Overpressure are injected, so that it completely encloses the connection region of the component and fills all the cavities and at the same time makes full contact with the connection area of the main body. After curing of the bonding compound results from both an intimate and high-strength connection of the parts as well as a handsome appearance of the joint, which is determined by the selected surface design of the recess of the molding.

By an embodiment of the method according to claim 2, the base body and the component are mutually fixed and prevents slipping of the parts. With a development of the method according to claim 3 - A -

the fixation of the parts achieved particularly easily and quickly.

With an embodiment of the method according to claim 4, the adhesion of the compound compound is improved on the glass.

By an embodiment of the method according to claim 5, adhesion or even sticking of the molded part to the base body and to the component is prevented.

An embodiment of the method according to claim 6 ensures that the separating agent can perform its separation function better than would be possible at ambient temperature. In addition, the reaction time of the curable bonding compound is favorably influenced, in particular shortened. In return, it may be appropriate to extend the starting time of the bonding compound, so that the bonding compound completely fills the cavity of the molding before curing begins.

The invention is also based on the object of specifying a device for carrying out the method. This object is achieved by a device having the features specified in claim 7.

By having a female part for the main body and for the component, these parts can be positioned in the correct mutual association in the device. Characterized in that the molded part, which projects beyond the connecting region of the base body and of the component and whose surface regions are adapted to these surface areas on the base body and on the component, is made of a flexible material, the molded part is tight on both parts create, even if in particular the main body should have greater dimensional tolerances. Characterized in that on the molded part has a matched to the connection region of the base body and the component recess for a curing compound, can be enclosed by filling the recess with such a compound compound of the connection area of the component and connected to the body.

Because pressure devices are arranged on the side of the molded part facing away from the base body and from the component, the molded part can be pressed firmly against these parts in the surface regions of the base body and the component which are located outside the connection region, thus allowing the material to escape into the recess Prevent filled compound compound. About the supply line connected to the recess, the compound compound is introduced into the recess of the molded part, in particular injected with overpressure.

An embodiment of the device according to claim 8, a full-surface support of the body and the component is avoided, so that shape tolerances of the two parts can be easily compensated.

By an embodiment of the device according to claim 9, the positioning of the base body and the component in the horizontal direction is facilitated.

An embodiment of the device according to claim 10 ensures that the molding is relatively small and can be handled accordingly easy. An embodiment of the device according to claim 11 ensures that the molded part is relatively simple and inexpensive to manufacture and that the molding of both parts is not hindered after the connection of the component with the base body. This is especially true in a development of the device according to claim 12.

An embodiment of the device according to claim 13 creates a boundary for the connection mass on one or both sides next to the connection region of the base body and the component, if such a limitation is not already present on the base body and / or on the component.

An embodiment of the device according to claim 14 provides a very flexible pressure device for the molded part, which easily compensates for form tolerances of the base body and / or of the component.

By an embodiment of the device according to claim 15, the force of the pressing device is distributed over a larger area of the molded part and thus reduces the local surface pressure.

In one embodiment of the device according to claim 16, the number of piston actuators is halved with the same force distribution on the molded part.

An embodiment of the device according to claim 17 ensures that the molding is permanently coupled to the pressure plates of the piston drives, so that both the placement of the molding on the body and the component as well as the lifting thereof is taken over by the pressing device and a separate handling of Mold part deleted. By a development of the device according to claim 18, this is achieved in a relatively simple and inexpensive manner.

In an embodiment of the device according to claim 19, only a single feeding device for the connecting mass is required, which simplifies and facilitates their operation.

In one embodiment of the device according to claim 20 is characterized in that the molded part is arranged in a direction towards the base body and the component open towards recess of a carrier and is guided movably until it rests against a stop, and in that between the molding and the bottom of the recess a pressure hose is arranged, a uniform pressure force is exerted in operation on the molded part over its entire length, which causes an equally uniform contact force of the molded part on the base body and the component. Characterized in that the carrier is guided on the guide device and is adjustable by means of the drive device between its rest position and its operating position, the molded part is indirectly moved between a rest position and an operating position. The fact that the adjustment of the carrier is greater than the measured in the rest position of both parts clear distance between the molding of the body and the component, puts the mold already before adjusting the carrier in its operating position on the body and the component, before marriage the carrier has completely reached its operating position. This ensures that the pressure exerted by the pressure hose on the molding force is not absorbed by the movement stop of the molding special effects in full height on the body and the component. In one embodiment of the device according to claim 21, the pneumatic piston drives assets can serve both as a guide device as well as a drive device.

An embodiment of the device according to claim 22 or alternatively according to claim 23 ensures that the molding and thus also the release agent applied thereto are brought to a temperature which is higher than the bypass temperature, which favors the function of the release agent. With the developments according to one of claims 24 to 26, this can be realized in a simple manner.

In one embodiment of the device according to claim 27, the adjusting device is relieved of having to absorb the reaction force of the pressure hose. With a development according to claim 28 and claim 29 simple designs are proposed for this.

In one embodiment of the device according to claim 30, the flow path for the connecting mass is reduced to a minimum and thus shortened the time period for the introduction of the bonding compound in the recess of the molded part, which also favors the curing process of the bonding compound.

From Fig.l front window of a passenger car as a base body 11 and a terminal block as a component 12 can be seen.

From Figure 2 is a cross section of the lower edge of the base body 10 and the component 11 can be seen in the final state, in which both parts are permanently connected to each other. The main body 11 forming windscreen is formed as a laminated glass.

The component 12 serves as a terminal block, by means of which a further component, for example a water tank, can be connected to the main body 11, namely can be hung or clipped thereto.

The terminal block 12 is formed in several parts. It has a metal frame 13, whose freestanding

Longitudinal edge as a locking edge 14 has the cross-sectional profile of a spring nose. This can be locked a matched profile section of the water box. In Figure 2, a Transportkeder 15 is clipped into the locking edge 14 instead of this profile section of the channel box. It is simply pulled out when the water box is to be used in its place during assembly of the motor vehicle. The other longitudinal edge of the metal frame 13 serves as a connecting edge 16. It is formed comb-like, the tines are alternately straight and angled.

In addition to the metal frame 13, the terminal block 12 on a plastic body 17, which serves as a spacer and positioning between the metal frame 13 and the glass sheet 11. The plastic body 17 has an approximately L-shaped cross-section and is located on the outer edge of the glass and on the adjacent disc surface. In this area, the plastic body 17 is attached to the glass pane 11 by means of a double-sided adhesive tape 18. At the opposite edge region, which adjoins the transport piping 15, the plastic body 17 is attached on its outside by means of a double-sided adhesive tape 19 to the inside of the metal framework 13.

In the final state shown in FIG. 2, the base body 11 and the component 12 are permanently connected to one another by a connecting mass 21, so that they form a structural unit 22, as can be seen from FIG. 1 and FIG. The manufacturing steps and the device used in this case are explained below with reference to FIGS. 3 to 9.

In the starting state shown in FIG. 3, the base body 11 and the component 12 are turned by 180 ° with respect to their installation position, so that the outside 23 of the glass pane 11 is directed downwards. In this initial state, the component 12 is already applied to the base body 11 and by means of the two double-sided adhesive tapes 18 and 19 attached to it. The later applied compound mass 21 (FIG. 2) is indicated by its dashed outline 24.

At the glass pane 11 is that portion of her

Disc surface, which adjoins the edge of the plastic body 17 and extends beyond the floor plan area of the metal frame 13 addition, referred to as the connecting portion 25 of the base body 11. He is clarified by a curly brace. As can be seen from FIG. 3, the metal framework 13 projects with its connecting edge 16 beyond the adjacent edge of the plastic body 17. This projecting region of the width extension of the metal frame 13 and its adjacent towards the locking edge 14 portion are referred to as the connecting portion 26 of the component 12, which is also illustrated in Fig. 3 by a brace. The two connection areas 25 and 26 overlap each other in part. Their external boundaries also form the lateral boundaries of the outline 24 of the subsequent potting 21st

For lateral delimitation of the free-flowing in the prior art bonding compound on the glass sheet 11 a boundary strip 27 and the component 13 a boundary strip 28 glued in such a way that their mutually facing side surfaces are aligned with the edge of the associated connection region 25 and 26 respectively. The boundary strips 27 and 28 are made of sponge rubber with closed pores.

The main body 11 and the component 12 attached thereto are jointly inserted as an assembly 29 in a manufacturing device 30 (FIG. 4) and therein by means of Connecting mass 21 (Fig. 2) permanently connected to each other.

Of the device 30, two assemblies can be seen in FIG. 4, namely the receiving group 31 located at the bottom and the forming group 32 arranged above it.

The receiving group 31 has a first receiving part 33 for the main body 11 and a second receiving part 34 for the component 12. Both receiving parts 33 and 34 are shown strip-shaped for the sake of simplicity. In reality, at least their contact surfaces are divided into individual sections, which are arranged distributed on a common carrier 35 taking into account the dimensional stability and dimensional stability of the base body 11 and the component 12.

At least one positioning element 36 for the horizontal positioning of the assembly 29 is provided on the common carrier 35. This positioning element 36 is designed and arranged such that the latching edge 14 of the component 12 (FIG. 2) can be applied thereto. Depending on the size of the base body 11, it is expedient to provide two or more positioning elements 36.

The forming group 32, as the main component, has a molded part 41 which is strip-shaped. Its ground plan course is matched to the plan view of the connection region 25 of the main body 11 and the connection region 26 of the component 12, as can be seen from FIGS. 5 to 7 and is very clearly illustrated in FIG. 8.

The molded part 41 is made of a flexible material, which is for example a thermoplastic. Important is that the plastic of the molding 41 does not bond with the hardening bonding compound 21 (Figure 2) and does not adhere to it.

The molded part 41 has on its underside a recess 42, which is matched to the connecting region 25 of the main body 11 and the connecting region 26 of the component 12 (FIG. 3). It takes up the connecting mass 21 (FIG. 2), as can also be seen from FIG. 7.

The molded part 41 projects beyond the connecting regions 25 and 26 both in both directions transversely to its longitudinal extension and in the direction of its longitudinal extent. To the recess 42 for the connecting portions 25 and 26 close to the outside, a surface area 43 and a surface area 44 at. They are matched to the flush with them surface areas of the body 11 and the component 12.

The surface areas 43 and 44 are arranged on the molded part 41 such that their trajectory is aligned with the delimiting strip 27 or the delimiting strip 28 which laterally delimit the space for the connecting compound 21 on the main body 11 and on the component 12. When lowering the molding 41 on the assembly 29, the two boundary strips 27 and 28 are partially compressed, as shown in FIGS. 6 and 7 can be seen.

When the assembly 29 is positioned on the receiving assembly 31 (Figure 5), the molding 41 is lowered onto the assembly 29 (Figure 6) and the bonding compound 21 injected into the recess 42 with positive pressure. So that the molding 41 is not lifted off, by means of a pressing device 50 on the molding 41 a sufficiently large force in the direction of the assembly 29 and thus exerted in the direction of the receiving group 31 down. In Fig. 6, this pressing device 50 is symbolically represented by a hollow arrow.

As can be seen from FIG. 8, the pressing device 50 has a number of pneumatic piston drives 51, which are arranged distributed uniformly along the longitudinal extent of the molded part 41. Their cylinders 52 are arranged on a common carrier 53. Their piston rods 54 are aligned with the molded part 41.

With a greater longitudinal extension of the molded part 41, it is expedient to turn on a pressure regulating device in the compressed air supply line of at least part of the piston drives 51 in order to be able to adjust the pressing force of the pressing device 50 more easily to different requirements along the longitudinal extension of the molded part 41.

At the free end of each piston rod 54, a bracket 55 is arranged made of metal, which has two arms 56. At the free end of the two arms 56 each have a pressure plate 57 is disposed of metal. Each arm 56 is pivotally connected to the associated pressure plate 57, by means of a ball joint 58, as will be explained in more detail with reference to FIG. 9.

As can be seen from FIG. 8, the pressing device 50 simultaneously serves as a lifting device for the molded part 41. For this purpose, the pressure plates 57 are coupled to the molded part 41 by means of coupling elements 61 (FIG. 9) in both directions of movement. In the downward direction and for pressing the molding, the underside of each pressure plate 57 cooperates with the top of the molding 41. For the coupling in the upward direction or stroke direction, the pressure plate 57 has a respective lateral extension 62 and 63 which are C-shaped in cross-section. The right in Fig. 9 located extension 63 is not directly connected to the pressure plate 57, but via an intermediate piece 64 which is releasably connected to the pressure plate.

On the molded part 41, the coupling elements are designed as strip-shaped projections 65 and 66. Instead of these strip-shaped projections 65 and 66, the coupling elements may be formed on the molded part 41 as grooves in the side surfaces of the molded part 41, in which the projections 62 and 63 of the pressure plate 57 engage.

In the case of each pressure plate, the ball-and-socket joint 58 is formed by arranging on the arm 56 a two-sided flattened ball head 67, which interacts with a ball socket 68, which is arranged on a respective side cheek 69 of a joint base plate 70.

The connection of the component 12 to the main body 11 takes place in the following manner.

The preassembled by means of the adhesive tapes 18 and 19 (FIG. 3) assembly 29 of the base body 11 and component 12 is introduced at raised mold part 41 in the receiving group 31, as indicated in Fig. 4 by the hollow arrow 71. Subsequently, this assembly 29 is positioned on the receiving group 31, as shown in FIG. 5 can be seen. The molding 41 is lowered by means of the lifting and pressing device 50 on the assembly 29 until the surface portions 43 and 44 of the molding 41 at the him opposite part of the assembly 29 tightly abuts, wherein the two boundary strips 27 and 28 are partially compressed. As a result, the cavity formed by the recess 42 for the potting compound 21 is closed to the outside.

By a supply line 72 (Fig. 8), the compound mass 21 is injected into the recess 42 of the molding 41. This supply line 72 is arranged at least approximately in the middle of the longitudinal extension of the molded part 41. At each of the two ends of the recess 42, an air outlet opening is arranged, so that the initially still liquid bonding compound can fill the recess 42 in a very short time and can penetrate into all cavities of the component 14 and also on the associated surface portion of the glass pane 11 and connect to it (Fig. 7).

After curing of the connecting mass 21 are the

Base body 11 and the component 12 via the connecting mass 21 with each other to the unit 22 permanently connected (Fig. 2). The molding 41 is lifted by means of the lifting and pressing device 50 and the assembly 22 is lifted from the receiving group 31 and transported away.

A modified embodiment of the main body 11 and of the component 12 as well as of the device 130 for its production will be explained with reference to FIGS. 10 to 14. Since the modification relates only to a few parts, the reference numbers of the first embodiment are used for the assemblies and items, which are only increased by the number 100. Insofar as individual assemblies and individual parts are not explained separately below, it can be assumed that they are the same or at least similar to the modules or parts of the first embodiment, the explanation is included here.

The modification consists mainly in that in the base body 111 and the component 112 to be connected to it, the boundary strips are missing, which in the base body 11 and in the component 12 (FIG. 3) as boundary strips 27 and 28, the connection region 25 of the base body 11 and the connection region 26 of the component 12 laterally limit and between which in the prior art, the bonding compound is poured freely. Regardless of the absence of the boundary strips is the metal frame 113 by means of the adhesive tape 119 on the plastic body 117 and this in turn by means of

Adhesive tape 118 attached to the base 111 (FIG. 10).

Despite the absence of the boundary strips, nothing changes in the nature and arrangement of the connection areas 125 and 126. Even at the contour 124 of the later connecting mass 121, nothing changes. This is achieved in that in the case of the forming group 132, the molded part 141 is modified in a corresponding manner with respect to the molded part 41 (FIG. 5).

The recess 142 for the connection mass 121 on the underside of the molded part 141 has remained the same as the recess 42. The surface areas 143 and 144 adjoining on both sides are adapted to the change in the main body 111 and the component 112.

On the underside of the molded part 141 includes in the surface area 143, a boundary strip 181 and in the surface area 144 a boundary strip 182, which are connected to the molding 141. They will be suitably Wise with him in one piece. The underside 183 of the boundary strip 181 is matched to the flush with her surface portion of the body 111. The underside 184 of the boundary strip 182 is matched to the aligned with her surface portion of the top of the metal frame 113.

It is expedient to produce a height section 185 of the limit strip 181 immediately adjacent to the lower side 183 and the height section 186 of the limiting strip 182 directly adjacent to the underside 184 of a material which is more elastic than that of the remaining part of the limiting strip, in order to achieve the sealing effect to improve against the injected into the recess 142 connecting mass.

When the subassembly 129 is positioned on the subassembly 131 from the base body 111 and the component 112 to be connected to it, the subassembly 141 is lowered by the lifting and pressing device 150 onto the subassembly 129 and pressed against it (FIG. 12). Subsequently, in the recess 142 of the molding 141, the initially liquid bonding mass 121 is injected under pressure so as to fill all the cavities of the recess 142 including those of the metal skeleton 113 (FIG. 13).

After the curing of the bonding compound 121, the molded part 141 is lifted by means of the lifting and pressing device 50 and the assembly 122 shown in FIG. 14 is removed from the base 111 and from the component 112 permanently connected thereto via the connecting element 121 and transported away. A modified production device is explained with reference to FIGS. 15 to 18, by means of which the assembly 132 (FIG. 14) can alternatively be produced from the base body 111 and the component 112 with the aid of the bonding compound 121. In this case, the device 130 with the receiving group 131 and the forming group 132 (FIG. 11) is taken over virtually unchanged. Therefore, the same reference numerals are used for these assemblies and items as in the second embodiment of FIG. 11 to FIG. 14. Only the pressing member for the forming group 132 is deviated from the pressing device 150. It will be explained in more detail below.

As can be seen from FIG. 15, the pressing device 250 has a carrier 251 which receives in its interior the entire forming group 252 (FIG. 16) and further parts. The carrier 251 is displaceably guided by means of a guide device 253 in the direction of the receiving group 131 with the base body 111 and the component 112 and away from it. At the same time, the guide device 253 serves as a drive device by means of which the carrier 251 can be adjusted between a rest position lifted from the base body 111 and the component 112 and an operating position approximated to the base body and the component.

The guiding and driving device 253 is constituted by pneumatic piston drives 254, four of which are shown. Their cylinders 255 are connected to a stationary holder 256. Their piston rods 257 are connected to the carrier 251. The joints are shown in Fig. 15 as a rigid screw 258. However, they can also be interconnected by means of a ball be connected articulated, as is the case in the manufacturing apparatus of FIG. 8.

The carrier 251 is matched to the plan shape of the molded part 141 and projects beyond the molded part 141 both in width and in length.

The carrier 251 accommodates the entire forming group 252 (FIG. 16), which corresponds to the forming group 132 of the second embodiment. For this, the carrier 251 has a U-shaped cross-section. The web of the U-profile forms the ceiling portion 261 and the two flanges of the U-profile form the side walls 262 and 263 of the carrier 251. The recess 264 bounded by the ceiling portion 261 and the two side walls 262 and 263

Carrier 251 is tuned in length and width on the molded part 141. It is completed at both ends by a respective end plate 265 (FIG. 15).

At the bottom 266 of the recess 264, a pressure hose 267 is arranged, the longitudinal extent of which is at least equal to that of the molded part 141. For a full-surface contact of the pressure hose 267 in the recess 264, the transition from the base 266 to the side walls 262 and 263 is rounded. The pressure hose 267 is filled with a pressure medium and connected to a pressure source, not shown, by means of which the required pressure force can be exerted on the molded part 141 during the introduction of the bonding compound 121 into the recess 142 (FIG. 12).

Between the pressure hose 267 and the molded part 141, a heating bar 268 is arranged. The molded part 141 is guided in the recess 264 in the direction of the holding group 131 toward and away from it. In the path of movement of the molded part 141 in the direction of the holding group 131, two abutment bodies 271 and 272 are fastened to the carrier 251, by means of which the movement of the shaped part 141 in the vertical direction, ie in the direction of the holding group 131, is limited to an end position which is shown in Fig. 16. The stopper members 271 and 272 have an L-shaped cross section. Your long profile leg 273 is screwed by means of screws 269 on the front side of the side wall 262 and 263 of the carrier 251. Their short profile limb 274 projects along the side wall 262 or the side wall 263 for a short distance into the recess 264 of the carrier 251 and serves as a stop bar 275 or 276 for the molded part 141.

The heating strip 268 lies loosely on the upper side 277 of the molded part 141. It is made of a metallic material. It has two longitudinally extending channels 278 for a heating medium. Instead, the heating bar 268 may also be provided with electrical resistance heating elements.

Instead of the arrangement of the self-contained heating strip 268, electrical resistance heating elements or channels for a heating medium can also be accommodated in the molded part 141 itself, if its cross-section and its material properties are suitable for this purpose.

The top 279 of the heating bar 268 is similar to the inside of the recess 264 matched to the outer shape of the pressure hose 267, in order to achieve at least approximately a full-surface investment. The displacement of the guide and drive device 253 of the carrier 251 is greater than the measured in the rest position of the carrier 251 clear distance of the molded part 141 of the base body 111 and the component 112, so that in the operating position of the carrier 251 (FIG 141 on the one hand rests on the main body 111 and the component 112 and on the other hand has lifted from the stop strips 275 and 276. As a result, the molded part 141 on the main body 111 and the component 112 can thereby be pressed with increased force and retained by placing the interior of the pressure hose 267 under overpressure. This prevents the molded part 141 from being lifted off the main body 111 and the component 112 when the connecting mass 121 is injected into the recess 142 between these parts (FIG. 12) under a certain overpressure in order to achieve the fastest possible complete filling To reach recess 142.

During the injection and until the curing of the bonding compound 121, the molding 141 can be held in the operating position by means of the guiding and driving device 253. To relieve the guide and drive device 253 of this task, either two pairs of locking devices or two pairs of clamping devices 281 are arranged (Figure 15). These are coupled on the one hand to the carrier 251 and on the other hand to the stationary holder 256.

The clamping devices 281 each have a push rod 282, whose lower end is connected by positive engagement, for example by means of a screw 283, with the carrier 251. At one of them Each push rod 282 is clamped by means of a clamping device 284 which is arranged on the stationary holder 256.

Instead of the clamping device 284, a locking device can be used, in which, for example, a locking part engages in a matching locking notch in order to achieve an unyielding positioning of the support 251 in its operating position by positive engagement.
