  • Publication number: 20230398647
    Abstract: A clamping device includes a zero-point clamping system, which can be actuated by a working medium; a machine vice, which can be coupled to the system; and a gripping and positioning device for transporting and positioning the machine vice on the zero-point clamping system. The zero-point clamping system contains at least one coupling element and the gripping and positioning device contains a docking device having at least one docking element, which can be coupled to the coupling element, for supplying the working medium to the system. To facilitate coupling, the at least one coupling element of the system is offset parallel to a receiving opening for a clamping element on the machine vice, and the at least one docking element is positioned in such a way that it is coupled to the coupling element by retraction of the clamping element located on the machine vice into the receiving opening.

  • Publication number: 20210016404
    Abstract: A gripping and positioning assembly for transporting a holding device between different positions includes a coupling arrangement for separably coupling the gripping and positioning assembly to the holding device and holding the holding device securely during transport. The gripping and positioning assembly has an integrated drive for moving the holding device between a hold and a release position to allow the operation of the holding device between a holding and a release position as well as a transporting of the holding device. The coupling arrangement has one or more aligning elements to provide an interlocking connection to the holding device.

  • Patent number: 9962812
    Abstract: A centric clamping device, which contains a main body, two clamping jaws, guided so they can be displaced on the main body, and an adjusting spindle, supported by a spindle bearing so that it can rotate on the main body for the opposing adjustment of the two clamping jaws. A high-precision spindle bearing, optimally protected against soiling, is attained in that the spindle bearing is located in a bearing block and two bearing sleeves, which can be adjusted axially within the bearing block.

  • Publication number: 20130168913
    Abstract: The invention relates to a zero point clamping device for clamping a first component (1) to a second component (2) at a precise position, wherein the first component (1) comprises at least one draw-in bolt (3) and the second component (2) comprises a receiving opening (4) for the draw-in bolt (3) and a clamping mechanism (5) for drawing in the draw-in bolt (3) into the receiving opening (4). According to the invention, the receiving opening (4) comprises an insertion area (12) having larger outer dimensions than the draw-in bolt (3) and a contact area (13) radially offset relative to the insertion area (12) and having at least one contact surface (14) having a circular shape in top view.
