A firearm maintenance aid can include a firearm vise and a firearm support device. Firearm vise can include vise jaws, a threaded rod connecting vise jaws together, and jaw pin holes in each jaw, the holes extending from an outer surface of a jaw through to an inner surface of each jaw, wherein the holes in the first jaw align with the holes in the second jaw. Firearm support device can include a clamping portion and a supporting portion. The clamping portion can be clamped between the jaws of the firearm vise, can include two parallel clamping faces, and can define vise pin holes that align with the jaw pin holes. The supporting portion can be located opposite the clamping portion and can include a cylindrical shaft. Vise pins can be received by the jaw pin holes and vise pin holes to fixedly connect the support device to the vise.

A vise jaw is provided, including: a first jaw, including a slide groove and at least one locking portion, each locking portion including a receiving room, a threaded hole and a through hole, the receiving room, the threaded hole and the through hole respectively communicated with each other; a second jaw, having a slide protrusion slidably disposed within the slide groove, the slide protrusion having a lateral face facing the through hole; at least one fastening assembly, each fastening assembly including a screw member, an abutting member and at least one elastic member, the screw member screwed into the threaded hole, the abutting member adjustably disposed within the receiving room, the abutting member including a large diameter section and a small diameter section which are arranged along a first direction, the small diameter section disposed through the through hole and extending into the slide groove.

The present specification discloses systems, devices, and methods provide a mounting system which includes rail and a bracket which is selectively secured to the rail. The bracket is selectively and/or automatically locked to the rail when positioned on the rail, and may be removed from the rail by activating one or more buttons or actuators. The disclosed mounting systems, devices, and methods enable a device to be protected from impact and moisture exposure, enable a device to be securely mounted on a base, and/or enable a device to be quickly secured and removed from a base.

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 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.

An apparatus for machining a component is provided. The apparatus includes a fixation mechanism, wherein the fixation mechanism includes a first fixation member with a first fixation face and a second fixation member with a second fixation face, wherein the first fixation face and the second fixation face are arranged and configured such that different bearing surfaces of a plurality of different components can be fixed between the first fixation member and the second fixation member, wherein the apparatus further includes a machining device, and wherein the apparatus is configured to machine a machining surface of the respective component by means of the machining device and according to a predetermined accuracy. Further, a method of machining the component is presented.

A band saw vice assembly for securing a substrate for cutting includes a base that has a first plate coupled to and extending vertically from a first side. A first bar, which is hollow, is coupled to and extends perpendicularly from the first plate. A second plate is coupled to and extends perpendicularly from a sleeve that is positioned around the first bar. A first slot and a second slot, which are aligned and perpendicular to the base, are positioned in the first plate and the second plate, respectively. An actuator, which is operationally coupled to the sleeve, is coupled to and positioned in the first bar. The actuator is positioned to motivate the second plate toward the first plate to frictionally couple to a substrate to fixedly position the substrate. The first and second slots are configured to insert a blade of a band saw to cut the substrate.
