A holding apparatus/workpiece adapter apparatus arrangement includes a holding apparatus and a workpiece adapter apparatus. The workpiece adapter apparatus is positioned and fixed, with a workpiece fastened thereto, by the holding apparatus. The holding apparatus has partially cylindrical positioning elements, which engage in an associated cylindrical positioning recess and a positioning slot and position the workpiece adapter apparatus in an x and a y direction. The workpiece adapter apparatus bears by mating contact surfaces against contact surfaces of the holding apparatus and is clamped by linearly displaceable clamping elements and pressed against the contact surfaces, and thus positioned in a z direction. For clamping, clamping surfaces of the clamping elements bear against mating clamping surfaces of the workpiece adapter apparatus.

A method for production of a motor vehicle that includes providing a device for positioning motor vehicle parts that comprises a base frame having at least one base module arranged thereon, and at least one exchangeable docking plate configured for connection to the base module, the at least one exchangeable docking plate having arranged thereon a plurality of receivers configured to hold the motor vehicle parts, transferring the at least one exchangeable docking plate to the base frame, connecting, at a configuration station, the at least one exchangeable docking plate to the base module, fitting, at a work station, a motor vehicle part to the at least one exchangeable docking plate, such that the motor vehicle part is held by the receivers, and equipping the motor vehicle part with add-on parts.

When an operation portion (38) provided at an axial end portion of a valve member (37) is pushed into a valve case (31) provided to a first block (3), a clamping apparatus transitions from a first state, in which communication between: each of a primary-side pressure fluid supply/discharge port (34) and a secondary-side pressure fluid supply/discharge port (35); and a pressure fluid discharge port (36) is open, to a second state, in which communication between: each of the primary-side pressure fluid supply/discharge port (34) and the secondary-side pressure fluid supply/discharge port (35); and the pressure fluid discharge port (36) is closed.

A rotary indexing table assembly includes an axis of rotation, a rotation element and a receiving assembly. The rotation element is rotatable about the axis of rotation and has a centering opening coaxial with the axis of rotation. The receiving assembly has a spring system and a pin assembly. The pin assembly has a pin body, movable along the axis of rotation by the spring system and settable in a set-up state or a blocking state. In the set-up state, the rotation element is releasably connected to the receiving assembly, and in the blocking state, the rotation element is fixedly connected to the receiving assembly.

The invention relates to a clamping arrangement with a clamping device (1) which is able to be fastened on a clamping base, and with a clamping element (26) able to be tightened thereon. The clamping device (1) has a clamping module (2), provided with clamping members (15), which is able to be fixed by means of a fixing element (3) on the clamping base, wherein the fixing element (3) is configured such that the clamping module (2) is thus fixed in the X-Y plane in a floating manner on the clamping base. The clamping module (2) is displaceable in the fixed state of the fixing element (3) with respect to the fixing element (3) in the X-Y plane, but is non-displaceable in Z-direction, wherein the fixing element (3) is provided with Z-support surfaces (24) for the clamping element (26). Such a clamping arrangement is suitable in a particularly advantageous manner as a module for constructing a large clamping system, with which thermally caused dimension changes of the workpiece carrier with respect to the clamping base can be equalized with high repeat accuracy, without the clamping system being overconstrained geometrically/mechanically in the X-Y plane.

A first rod (21) is inserted into a first guide hole (11) so as to be movable in a vertical direction. A second rod (22) is inserted into a second guide hole (12), which crosses the first guide hole (11), so as to be movable in a horizontal direction. An accommodation groove (31) is disposed in a lower half portion of the first rod (21). The second rod (22) is provided with an insertion portion (32) to be fitted in the accommodation groove (31). A cam groove (38) provided in the insertion portion (32) is fitted over a pin (35) provided in the lower half portion of the first rod (21). A driving means (D) connected to the second rod (22) moves the second rod (22) in the horizontal direction.

A workpiece clamping device able to perform a set-up changing operation for clamping members depending on the kind of a workpiece to be processed, at a low cost, by a simple method. The workpiece clamping device includes a bracket, a movable part which is movable with respect to the bracket, a clamping member to be attached to and detached from the bracket or the movable part, to clamp a workpiece, and a detachable device for detachably coupling the bracket or the movable part to the clamping member.

A device for positioning motor vehicle parts in the production or manufacture of motor vehicles. The device includes a main frame, at least one main module configured to be disposed on the main frame, at least one interchangeable first docking plate configured for releasable connection to the main module, and a plurality of first receptacles, arranged on the interchangeable first docking plate, configured to hold the motor vehicle parts at a predefined position during the production.

A pallet clamp includes a clamp receiver 110 and a clamp 130. The clamp receiver 110 has an abutted surface 111 with serrations, whereas the clamp 130 has an abutting surface 132 with serrations. The clamp receiver 110 has both of a pressed surface 180 and a counter pressed surface 181 which face in directions perpendicular to the direction along the extension of the serrations. A biasing means 150 press-fits the clamp receiver 110 and the clamp 130 to each other so that the abutting surface 132 and the abutted surface 111 come into tight contact with each other, which causes the pressed surface 180 and the counter pressed surface 181 to be pressed in opposite directions.
