A vise having a modular construction that allows for ease of manufacture, assembly, and changeover or replacement of wear items, such as gripping surfaces of jaws of the vise. The modular construction also provides for reduced weight of the vise compared to conventional cast type vises. The vise also incorporates quick adjustment features allowing for the vise to be easily rotated, a position and size of an opening of the jaws to be rapidly adjusted, and a clamping force applied with ease.

A woodworking vise includes a profiled vise body (1), a first jaw (2) and a second jaw (2′). The first jaw (2) and the second jaw (2′) are disposed at both ends of the vise body along its longitudinal axis. The woodworking vise further includes at least one movable jaw (3). The at least one movable jaw (3) is slidably connected to a top surface of the profiled vise body. Between the movable jaw (3) and the top surface of the profiled vise body (1), a locking block (36) is disposed, and a bottom surface of the locking block (36) is slidably connected to the top surface of the profiled vise body (1). The movable jaw (3) includes a force applying means (34) and a camshaft (35). The camshaft (35) has at least one cam, and the force applying means (34) is connected to the camshaft (35). Moreover, the force applying means (34) is able to rotate about a center axis of the camshaft (35) to drive the camshaft (35) to rotate therewith to cause the cam of the camshaft (35) to press against the locking block (36) and, by means of the locking block (36), press and secure the movable jaw (3) against and to the top surface of the vise body (1). Wherein, the center axis of the camshaft (35) is perpendicular to the longitudinal axis of the profiled vise body (1). This woodworking vise can solve the problem of an angle of clamping deviation.

A workpiece clamping device having at least one base body. A first clamping body and a second clamping body are movably supported on the at least one base body in a clamping direction. A threaded spindle extends along a spindle longitudinal axis. The spindle longitudinal axis is orientated in clamping direction. It has a first thread section for the first clamping body and a second thread section for the second clamping body. A first coupling body has a first counter thread portion and a second coupling body has a second counter thread portion. In a coupling position the counter thread portions are in engagement with the assigned thread section respectively. In a decoupling position the counter thread portion is disengaged from the assigned thread section. In this decoupling position a movement of the clamping bodies is possible without rotation of the threaded spindle.

A device for holding in position a product to be processed includes a base connectable by magnetic interaction to a work surface of an apparatus for tumbling or polishing and comprising a first portion and a second portion movable along an operating direction mutually towards or away from a first and a second operating position. The device also includes a retaining support connected to the base and configured to hold in a stable position a product to be processed between a first and a second retaining element. Between the first and the second portion of the base an actuation member is interposed, configured to move the same portions between the first operating position and the second operating position. A method for holding in position a product to be processed is also disclosed.

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.
