Definitions

  • the invention relates to a drive unit for tensioning devices, that is, especially for so-called push rod tensioners for fixing workpieces, consisting of a Housing from which a linear adjustable, mounted in the housing Push rod is led out of this and further in the Housing in the area next to the push rod assembly a drive member is arranged, the output member with the im Housing located end of the push rod is in communication.
  • Such a drive unit is, for example, according to DE-A-101 18 319 A1 known.
  • a drive member here is only one Linear drive possible, whose actuator or piston rod a Crosspiece for the articulated connection of a two-part toggle lever chain having, with its second member on in the housing located end of the push rod is articulated.
  • the two in consequence to the crosspiece subsequent joints of the Link chain are guided in a groove, which is with a first part extends in the extension direction and then in a Elbow passes to the chain in relation to the push rod to bring levers to action, with in clamping position the second link connected to the push rod then essentially in the same direction as the extended push rod is oriented.
  • the force line guide from the drive link to push rod and vice versa here is relatively unfavorable and the forces involved must be equipped with rollers Joints with line contact via curved groove walls in the Housing initiated or absorbed by this.
  • the invention is based on a drive unit of the type mentioned above, the object of this, to that effect remodel and improve that the push rod with both linear and rotating drive links is actuated, where in clamping position and in both cases, the two toggle links essentially a continuation of the pushrod extension form and thus the clamping load with improved Lines in linear continuation of the push rod in the housing can be introduced.
  • connection between the output member of the drive and the end of the push rod is formed of an adapter and one of three connected by a common joint members toggle lever drive, wherein the free end of the first member at the end of the push rod, which is hinged to the second, the pressure member forming member on the adapter and the third member in a housing support bearing, which is arranged in the housing on the extension line of the push rod, wherein the members and the adapter in such a way are assigned, that the members are oriented in clamping position in the extension straight line of the push rod.
  • Groove guides in the housing for those involved in the toggle lever system Joints are not required, that is, only at linear Force introduction by a likewise arranged in the housing with For example.
  • Pneumatic cylinder requires the appropriate adapted Adapter of a straight guide in the housing, and in electromotive Drive is the load introduction into the housing exclusively via the housing support bearing.
  • the drive unit consists of a housing 1, one of which linearly adjustable, mounted in the housing 1 push rod 4 made this is led out and further wherein in the housing 1 in the area in addition to the push rod assembly, a drive member. 5 is arranged, the output member 6 with the housing in the first located end 4 'of the push rod 4 is in communication.
  • the 1 embodiment shown already has special features on, which will be explained later.
  • This housing support bearing is in the housing 1 on the extension straight line G of Push rod 4 presentation oriented arranged below this wherein said members 9, 10, 11 and the adapter 7 are associated with each other such that the members 9 and 11 in Tension position in the extension straight G are oriented, such as these illustrate Figs.2 and 4.
  • the drive members 5 are shown in FIGS. 2 to 5 only dashed indicated, wherein it is in the Fig.2,3 example. To a Pneumatic cylinder and in the Fig. 4.5 to an electric reversing motor is.
  • the adapter 7 is in the form of a guided in the housing 1 with double rollers 2 and to the output member 6 (piston rod) of the drive member 5 in a suitable manner coupled gate 7 'formed while a rotary drive of the adapter 7 in the form of a with a worm 6 'of the output member 6 (motor shaft) of the servomotor 5 "meshing Schneckenradsegmentes 7" is formed, wherein, as shown in Figures 4,5, the worm wheel segment 7 "conveniently sits directly on the housing support bearing 13, but freely rotatably mounted on this can be.
  • the respective desired drive 5 and the to be able to install associated adapter 7 manufacturer side is the joint connection 14 for the pressure member 10 in a case the scenery 7 'and in the other case on the worm wheel segment 7 ", which form the respective adapter 7, functionally equivalent in itself Positions arranged, denoted by S and S ' are. So for the manufacturer, there is the advantage optionally one or the other drive 5 with associated Adapter 7 with otherwise the same housing 1, same push rod and the same toggle lever system 12 to install.
  • the two rods 4 'shown in the exemplary embodiment are guided in a common rod guide or in individual rod guides 4 "(as shown) in the passage area in the housing 1. In this way, the otherwise the normal and clear lines of force in the control mechanism impairing torsional stresses are already recorded in the penetration range of the rod guides 4 ".
