An embodiment of a vise may include a clamping structure having a first clamping jaw, a second clamping jaw positioned relative to the first clamping jaw, and a quick adjust jaw guide to maintain the first clamping jaw relative to the second clamping jaw. The quick adjust jaw guide may include a driving element to apply a force to move the first clamping jaw relative to the second clamping jaw, wherein the driving element comprises a release structure to release the applied force to facilitate rapid adjustment of the first clamping jaw relative to the second clamping jaw.

An armorer tool system for distributing the applied torque over a very wide surface, associated with assembling and disassembling primarily the barrel and the lower receiver extension of an AR platform firearms, independently of the specifications of their barrel extension, lower receiver and upper receiver external features, and magazine well geometry; and methods of using the tools are also disclosed.

A self-centering vise structure includes a vise body, a guide screw, a positioning unit, a first movable jaw unit, and a second movable jaw unit. The vise body is provided with a guide way. The positioning unit is provided with two fixed portions each provided with an elongate slot. The positioning unit is provided with two locking screws each extending through the elongate slot of each of the two fixed portions and is screwed into the guide way of the vise body. The elongate slot of each of the two fixed portions is moved relative to each of the two locking screws, and the positioning unit is moved relative to the vise body, to micro-adjust a central location of the self-centering vise structure.

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 machine-tool vise is described that employs an articulated two-piece movable jaw including a jaw nut that engages the lead screw and a jaw bit coupled to the jaw nut through a slanted interface wherein the slanted interface between the nut and the bit is located at the top of the bit to eliminate the secondary effects found in the prior art.

A clamp release mechanism is provided. The clamp includes a body, a shaft slideably coupled to the body, a fixed jaw, and a moveable jaw coupled to the shaft. A locking component actuates between a locked position and an unlocked position. When in the locked position, the locking component biases the shaft to remain stationary with respect to the body. The clamp includes a securing component pivotally coupled to the locking component, and a biasing element that biases the securing components towards the shaft.

Example implementations relating to a mechanical vise are disclosed herein. In one particular implementation, a first jaw piece includes a first slip surface a second jaw piece includes a second slip surface. The first slip surface may be moveable with respect to the second slip surface, while in slip contact with the second slip surface, to at least in part apply a force against a workpiece.

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.

An embossing device that serves for preparation of a combined form-fit and friction-fit clamping of a workpiece in a respective clamping chuck. The embossing device includes jaws having embossing teeth that are formed on insertion bodies. The insertion bodies include a penetration edge respectively with which they penetrate into the workpiece surface in order to create a depression with defined dimensions. For this a workpiece contact surface is formed on the insertion body, preferably in the proximity to the bar-like projection that stops the penetration process of the bar-like projection as soon as the workpiece contact surface gets in contact with the workpiece surface during the execution of the embossing process. Then the force required for movement of the jaw increases considerably from which a control device generates a switch-off signal for the operation device.

An embodiment of a vise may include a clamping structure having a first clamping jaw, a second clamping jaw positioned relative to the first clamping jaw, and a quick adjust jaw guide to maintain the first clamping jaw relative to the second clamping jaw. The quick adjust jaw guide may include a driving element to apply a force to move the first clamping jaw relative to the second clamping jaw, wherein the driving element comprises a release structure to release the applied force to facilitate rapid adjustment of the first clamping jaw relative to the second clamping jaw.
