A vise includes a pair of clamping jaws defining a cavity therebetween for holding a workpiece or tool, a primary screw for moving the pair of clamping jaws toward and away from one another, thereby allowing a workpiece or tool to be clamped in a first direction, and an anvil extending outwardly from a first clamping jaw of the pair of clamping jaws.

A workpiece clamping device having a first base body on which a first clamping body is slidably supported in a clamping direction, as well as a second base body on which a second clamping body is slidably supported in the clamping direction. The two clamping bodies are in engagement with a threaded spindle. A contact surface is provided on each base body on the side that faces the other base body respectively. The contact surfaces are arranged with base body distance in the clamping direction. A centering body of the threaded spindle has centering surfaces that abut at one assigned contact surface respectively in order to position the threaded spindle in clamping direction without clearance as far as possible.

A pressure applying system using a modular vise having a fixed base and an adjustable pusher assembly. The modular vise utilizes a bi-directional worm screw to apply a linear force from the pusher assembly to the working member relative to the fixed base. The fixed base is secured and located from below a bottom surface of the fixed base.

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 clamping device for fastening an injection mold to a tool plate comprises an upper part and a lower part, said lower part having a mounting surface arranged flat against the tool plate. First, second, third and fourth side surfaces upstand from said mounting surface, said upper part having first, second, third and fourth side surfaces. Said upper and lower parts are connected by a first bolt having an axis of symmetry defining an axis. A resilient member is arranged in connection with the first bolt between the upper and lower parts concentrically with the bolt's axis. The first bolt has a non-threaded section such that the lower part or upper part may move along the bolt in the direction of the axis.

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.

A power vise including a body and a jaw connected to and extending from the vise body. The vise can also include an actuator extending at least partially through the jaw body, where the actuator can include a first end and a second end opposite the first end. The vise can include a moving jaw connected to the first end of the actuator. The vise can include a motor connected to the second end of the actuator, where the motor can be operable to move the actuator to move the moving jaw with respect to the fixed jaw, including a hammering or impacting function, and that such hammering or impacting can be performed after a predetermined delay. The vise can include a sensor configured to produce a signal based on a condition of the vise and to control the vise at least in part on using that signal.
