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 work holding device includes a first jaw piece having an elongated first connection member for connecting the work holding device to a support. The first connection member defines a first passage. A second jaw piece has an elongated second connection member positionable within the first passage. The second connection member defines a second passage in communication with the first passage. A spindle assembly movably couples the second jaw piece to the first jaw piece. The spindle assembly is configured to move the second jaw piece with respect to the first jaw piece to create a clamping pressure when an object is placed between the first jaw piece and the second jaw piece.

This disclosure is directed to a method for forming and using one or more workpiece securing devices to reduce the deflections and vibrations of the workpiece during machining, as well as the time and labor associated with machining multiple workpieces. The method includes depositing material onto a surface of a movable jaw of a vise to form a first jaw protrusion and depositing material onto a surface of a stationary jaw of the vise to form a second jaw protrusion. A workpiece can be secured between the first and second jaw protrusions and then can be machined.

A vice jaw deflecting structure, comprising a vice main body, a lead screw positioning seat, a lead screw, a first flexible jaw set and a second flexible jaw set; the guide slot of the vice main body has a bottom surface, a first side wall surface, and a second side wall surface; the first flexible jaw set and the second flexible jaw set have a slide, a jaw and a limiting component; the slide is configured with a limiting block protruding toward the jaw, the limiting block protrudes toward the lead screw positioning seat and is formed with a -shaped stop block having a curved top view; the jaw bottom surface has a first convex wall surface and a second convex wall surface matching and contacting the first side wall surface and the second side wall surface.

An apparatus for converting a single-station vise to a double-station vise includes a pair of end converter jaws, a central converter jaw, and two pairs of shafts configured to extend along opposite sides of the single-station vise. Each of the shafts in the first pair is mounted for sliding movement relative to the first end converter jaw and fixed with respect to the second end converter jaw; each of the shafts in the second pair is fixed relative to the first end converter jaw and mounted for sliding movement relative to the second converter jaw; and all of the shafts are mounted for sliding movement relative to the central converter jaw.

A clamping jaw for the clamping of a workpiece, with a body and several clamping inserts arranged in mounting openings of the body made of a sintered material. The clamping inserts are designed in the form of cylindrical pins projecting relative to an end surface of the body and inclined relative to a lower base surface of the body with a clamping edge for forcing the clamping inserts into the workpiece.

A work holding device includes a first jaw piece having an elongated first connection member for connecting the work holding device to a support. The first connection member defines a first passage. A second jaw piece has an elongated second connection member positionable within the first passage. The second connection member defines a second passage in communication with the first passage. A spindle assembly movably couples the second jaw piece to the first jaw piece. The spindle assembly is configured to move the second jaw piece with respect to the first jaw piece to create a clamping pressure when an object is placed between the first jaw piece and the second jaw piece.

A vise system is provided to retain a workpiece. In an embodiment, the vise system comprises one or more center vise and one or more end vises. The center vises and end vises are clamped to a table or workbench. The center vise is provided with a front jaw and a rear jaw to retain the center of the work. The end vises are provided with workpiece clamps to retain the ends of the workpiece.

A fixing jig includes a support plate for supporting a workpiece. A fixing member is arranged on the support plate and defines a receiving groove penetrating a bottom surface of the fixing member. A stopper is slidably received in the receiving groove. A bottom surface of the stopper is flush with the bottom surface of the fixing member and contacts the support plate. An end of the stopper extends out of the receiving groove and abuts against the workpiece. The adjusting member is coupled to the fixing member. One end of the adjusting member extends into the receiving groove and is coupled to the stopper. The adjusting member is used to adjust a position of the stopper. The locking member is arranged on the adjusting member and used to lock a position of the adjusting member, thereby locking the position of the stopper.

A vise for holding a workpiece that reduces jaw lift having a vise base with a longitudinally extending guide channel that includes vise base flanges with base flange guide surfaces, the vise having vise trucks that move longitudinally within the guide channel, the vise having jaws that are selectively securable relative to the trucks wherein the jaws and the trucks include lift surfaces that move the trucks toward the jaws transversely to the longitudinal direction as the jaws engage the workpiece to lock the jaws and the trucks relative to the guide channel when the workpiece is clamped in the vise.
