When the cover plate 30 is close to the upper end surface of the clasp body 11, the accommodating portion and the protruding portion 41 are docked and matched, thereby determining the setting position of the clasp assembly 10, the axial position of the housing 100 and the upper cover plate 30 is determined, and the upper The axial position of the cover plate 30 and the ring body 11 is determined, the relative position of the ring body 11 and the cylindrical structural member 200 is determined, and finally the axial position of the shell 100 and the structural member is determined, and the central axes overlap to ensure that the cylindrical structural member 200 shape while ensuring the coaxiality of the suit.

In order to ensure the unobstructed insertion of the cylindrical structural member 200 and at the same time ensure the effect of shape control, as a preferred implementation, the diameter of the inner cavity of the ring body 11 is 0.1 mm to 1 mm larger than the outer diameter of the cylindrical structural member, which can Effectively avoid deformation during the suiting process.

This embodiment does not limit the specific structure and composition of the clasp assembly 10. In some embodiments, the clasp body 11 with different diameters and axial lengths can be designed for cabins of different sizes. Specially designed different hugging rings. Because the ring body 11 needs a certain structural strength, the material used for it generally costs a lot. In order to save costs, as a preferred embodiment, the ring assembly 10 also includes a support frame 12, and the ring body 11 is detachably connected to the support frame. The top surface of 12; the support frame 12 is provided with a support foot plate 13, and the locking mechanism 25 is used to locate the support foot plate 13 on the work platform, thereby reducing the axial length of the ring body 11 and reducing materials used. In some embodiments, one support frame 12 can be used for the connection and fixation of multiple ring bodies 11 , and it can also meet the common use of ring bodies 11 of different sizes by providing multiple turns of connection holes and pin holes.

This embodiment does not limit the specific structure of the support frame 12. For example, in some embodiments, the support frame 12 can be a solid structure. In some embodiments, in order to reduce weight, facilitate handling, and control costs, the support The frame 12 can also be designed as a frame structure.

In order to avoid the loss of glue used for curing in the curing step after the cylindrical structural member 200 with a through hole and the housing 100 are assembled, in this embodiment, the tooling also includes a flow guide 50, and the flow guide 50 includes a connection The cylindrical section 51 and the conical section 52, the large-diameter end of the conical section 52 is connected to the cylindrical section 51, the outer diameter of the cylindrical section 51 is equal to the maximum outer diameter of the conical section 52, and the end surface of the cylindrical section 51 is used to fit the shell 100 The connection and fixing of the guide ring and the housing 100 directly use the threaded holes on the end surface of the housing 100 without changing the structure of the housing 100 . In this embodiment, the structural shape of the guide ring is not specifically limited, and the guide member 50 may be a disc or a ring.

In order to further play the role of diversion and reduce the amount of glue loss, as a preferred embodiment, the inclination angle of the generatrix of the conical section 52 is 0.5° to 5°; The outer diameter is 0.1mm~4mm smaller.

In order to realize the visual observation and judgment when the suit is in place, as an embodiment, the tooling also includes an adapter plate 60 detachably connected to the upper end surface of the ring body 11, so that the top surface of the adapter plate 60 and the cylindrical structural member 200 The upper end surface of the housing 100 is flush with the upper end surface, and the adapter plate 60 is used to contact the upper cover plate 30. The upper cover plate 30 is also provided with a sinking groove matching the end size of the housing 100. Through dimension design, the upper cover plate 30 is in contact with the upper cover plate 30. When the adapter plate 60 on the ring body 11 is in contact with each other seamlessly, it means that the casing 100 and the cylindrical structural member 200 are fitted in place, and the measuring standard can be visualized. It should be noted that different cabins have different sinking depths, which are adjusted adaptively according to the design requirements of the cabins and suit size requirements, and are not specifically limited in this embodiment.

In order to prevent the assembly problem caused by the rotation or axial movement of the cylindrical structural member 200 caused by environmental vibration or interference during the assembly process, in this embodiment, the number of adapter plates 60 is at least two, and at least two adapter plates 60 The adapter plates 60 are arranged at intervals along the circumference of the ring body 11 , that is, within the circumference of the ring body 11 , the coverage of the adapter plate 60 is less than 360°. The tooling also includes at least one pressing block 70, which is detachably arranged on the upper end surface of the ring body 11, and is used to press the cylindrical structural member 200 and position the cylindrical structural member 200, thereby effectively preventing the cylindrical structural member 200 from rotating in the circumferential direction. , Quadrant dislocation.

Since the lower end surface of the upper cover plate 30 needs to be in contact with the top surface of the adapter plate 60, but the height of the pressure block 70 must be higher than the adapter plate 60, in order to ensure that the upper cover plate 30 and the adapter plate 60 are in place and visualized, this paper In the embodiment, the upper cover plate 30 is also provided with a gap, so as not to interfere with the installation of the pressure block 70 .

This embodiment does not specifically limit the setting method of the positioning structure 40, and the receiving part and the protruding part 41 of each positioning structure 40 can have two setting methods, that is, the receiving part is arranged on the upper cover plate 30 or the protruding part 41 It is arranged on the upper cover plate 30, so when there are more than two positioning structures 40, there are at least four types of their arrangement.

In order to save space and effectively utilize the characteristics of the suit, as an embodiment, the protruding parts 41 are all arranged on the upper surface of the ring body 11 , the protruding parts 41 are positioning pins, and the accommodating parts are pin holes on the upper cover plate 30 .

In some embodiments, the position of the protrusion 41 and the adapter plate 60 can be staggered, that is, the protrusion 41 is only matched with the adapter plate 60. In some embodiments, a through hole for the protruding part 41 to pass through may also be provided on the adapter plate 60, and the protruding part 41 fits with the receiving part after passing through the through hole.

This embodiment does not specifically limit the setting form of the work platform on the frame 20. For example, in some embodiments, the work platform is integrally formed on the frame 20. At this time, the ring assembly is determined by the trial assembly before applying glue. After the position of 10, the clasp assembly 10 and the cylindrical structural member 200 can no longer be moved. At this time, glue brushing work needs to be carried out in the space of the frame 20. In order to avoid the difficulty of brushing glue caused by the limited space of the frame 20, in some embodiments, the frame 20 is provided with a mounting platform 26, and the tooling also includes a lower base plate 27, which is movably connected with the mounting platform 26 through positioning pins; the lower base plate 27 constitutes a work platform, and the locking mechanism 25 is located on the lower base plate 27, so that when applying glue, the positioning pins of the lower base plate 27 and the installation platform 26 can be removed, and the lower base plate 27 and the lower base plate 27 are fixed on the lower base plate 27 by the locking mechanism 25. The clasp ring assembly 10 is removed as a whole, which is convenient for glue brushing, and during the formal assembly, the positions of the lower bottom plate 27 and the installation platform 26 are the same as the positions during the trial assembly under the action of the positioning pins, which ensures that the formal assembly and the trial assembly process are held in place. The positions of the ring assembly 10 and the cylindrical structural member 200 remain unchanged, and they can be directly assembled without hindrance, which is conducive to improving process efficiency.

In some embodiments, as shown in FIG. 1 and FIG. 3 , in order to facilitate the insertion and removal of the lower base plate 27 and the ring assembly 10 , a slide rail 28 is provided on the installation platform 26 , and the lower base plate 27 is slidably matched with the slide rail 28 , so that the lower bottom plate 27 and the upper workpiece can be pulled out as a whole when brushing the glue, and then pushed back to the inside of the frame 20 after the glue brushing is completed, and the positioning pins are used to ensure that the position is consistent with the trial assembly.

In order to ensure the verticality of the vertical direction during assembly, the frame 20 is provided with a horizontal adjustment mechanism 29, so that the installation platform 26 and the drive assembly 22 on the installation platform 26, the upper top plate 21 and other structures can be placed horizontally or moved vertically.

This embodiment does not specifically limit the specific implementation of the drive assembly 22 , for example, in some implementations, it may be a purely electronically controlled automation mechanism, and in some implementations, it may also be a manually controlled lifting mechanism. As a preferred implementation mode, in order to realize the combination of electric control and manual control, the quality of the suit can be ensured by manually controlling the lifting speed, and a system problem caused by excessive impact force can be avoided. In this embodiment, as shown in Figure 1, The driving assembly 22 includes an electronically controlled transmission mechanism 23 and a manually controlled pressure applying mechanism 24. Both the transmission mechanism and the pressure applying mechanism can control the lifting of the upper cover plate 30. For example, the transmission mechanism can be a ball screw pair or a linear motor. The mechanism is guided and matched with the upper top plate 21; the pressure-applying mechanism can be a hand wheel type worm and gear mechanism.

It should be noted that, in order to avoid over-positioning, in this embodiment, preferably, a certain adjustment margin is provided for the connection between the upper top plate 21 and the upper cover plate 30, for example, the size of the threaded hole may be slightly larger than the size of the bolt, Over-positioning caused by the direct positioning of the upper cover plate 30 and the upper top plate 21 and the direct positioning of the ring assembly 10 and the working platform by positioning pins is avoided.

This embodiment does not limit the optional solution of the locking mechanism 25. For example, in some embodiments, the locking mechanism 25 can be a plurality of screw-type telescopic adjustment parts fixed on the work platform and distributed in the circumferential direction of the ring assembly 10. After the position is determined, the positioning can also be realized by acting on the peripheral surface of the clasp assembly 10 through a plurality of screw-type telescopic adjusters. In this embodiment, the locking mechanism 25 is a positioning block similar to the working principle of the pressing block 70. The positioning block is detachably connected to the work platform. When the ring assembly 10 needs to be fixed, the positioning block is fixedly connected to the work platform. The foot plate is arranged between the positioning block and the operation platform, and the positioning block presses the foot plate on the operation platform, limiting the movement of the ring assembly 10 .

As shown in Figures 1 and 3, in order to improve the versatility of the frame, the frame can be used for the assembly of cabin sections of different sizes. A plurality of positioning blocks on the top can selectively press the support foot plate of the support frame through several of the positioning blocks.

The tooling provided in this embodiment, the frame 20 is used to assist the whole assembly process, wherein the upper top plate 21 and the upper cover plate 30 are connected by screws, the upper top plate 21 is not a fixed structure welded by machinery, and the upper cover plate 30 connected thereto can be Do micro-adjustment, the foot plate of the ring support and the lower base plate 27 cannot be relatively displaced after being positioned by the locking mechanism 25, and the lower base plate 27, that is, the working table surface and the large table top of the whole device are connected with positioning pins to ensure that it is level and positioned. This structure can ensure that the ring is in a horizontal and controllable position. Since the upper cover plate 30 and the housing 100 can be slightly adjusted as a whole, the end face of the ring is used as the reference in the structure during the assembly process. As shown in Figure 7, the machine Rack 20 can be used for the set of different products, forming rolling production.

Example 2

Based on the same inventive concept, this embodiment provides a set-up molding method based on the tooling in Example 1. The set-up molding method includes the following steps:

Since the connection between the upper cover plate 30 and the upper top plate 21 has a certain adjustment margin, it is necessary to pre-determine the installation position of the collar assembly 10 , that is, the central axis position of the housing 100 , during assembly. The installation position of the ring assembly 10 can be determined through the trial fitting operation. Specifically, the trial fitting is positioned, the upper top plate 21 is driven down by the drive assembly 22, and the position of the ring body 11 is adjusted so that the ring body 11 and the upper cover plate 30, the protruding part 41 and the receiving part are docked and slidably fitted to determine the docking position of the clasp body 11 on the work platform, and the clasp body 11 is locked and positioned by the locking mechanism 25; that is, the clasp body 11 in the subsequent steps 10 and the relative position of the operating platform no longer changes.

The upper top plate 21 is driven up by the drive assembly 22 to separate the housing 100 from the cylindrical structural member 200, and glue is applied to the inner bonding surface of the cylindrical structural member 200;

The upper top plate 21 is driven down by the driving assembly 22, and the housing 100 and the cylindrical structural member 200 are assembled and solidified to obtain a cabin section. Since the relative positions of the housing 100 and the cylindrical structural member 200 have not changed, the rotation is realized. The high-efficiency package of body composite structural parts solves the problems of debonding and deformation.

In order to ensure the bonding quality of adhesive curing and improve the overall quality of the finished product, in this embodiment, during the process of fitting the casing 100 and the cylindrical structural member 200 and performing curing treatment, the fitting molding method also includes, During the process, pay attention to the amount of glue in multiple places in the circumferential (circumferential) direction. If there is no excess glue, replenish it to ensure that the excess glue in the circumferential direction can be absorbed after the negative pressure is formed due to the change of the gap during the assembly process. into the gap, to fill the gap between them.

In order to stabilize the quality of the obtained compartment and further solve the problems of debonding and deformation, in this embodiment, the fixed glue is selected from silicon-based suit glue, which has the same composition, viscosity and process window as traditional suit glue. There is a big difference, although its viscosity is relatively large, which makes the process difficult, but it has the ability to coordinate strain at high temperature. The process window of the set glue is 5min~60min, which can be adjusted according to the ratio of the glue solution, and the glue can be replenished at any time during the process.

To sum up, the package molding method provided in this embodiment, based on the work provided in Example 1, is implemented with specific steps as follows:

(1) Adjust the working platform and the installation platform 26 of the whole frame 20 to the level by using a horizontal leveling mechanism, then push the lower bottom plate 27 into the frame 20 along the slide rail 28, and use the positioning pins to align the working platform and the installation platform 26 its positioning.
