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 clamping means system including a bearing device and clamping vices, which fit into the bearing device and respectively have on their base area machine coupling system and on their side faces and flanks a bearing receiving contour and a gripping receiving contour. The bearing receiving contour has the greatest play; the fit between the gripper and the gripper receiving contour is of moderate precision, while the precision of the machine coupling system is the greatest. The clear functional separation between the machine coupling system and the bearing receiving contour or gripper receiving contour allows a reliable low-cost system to be constructed. Furthermore, in the case of mixed partly automated systems, in which parts of the handling tasks are performed by the operator and other parts are performed by gripping robots, the handling is possible in an easy and intuitive way.

In a clamping device (1), in particular vice, the clamping device comprising: a housing (2) which is U-shaped in cross-section and in which one or two guideways (8) extending in a linear direction are incorporated, at least one base jaw (11) which is mounted in the guideway (8) and in which an internal thread (12) is provided, and a drive spindle (9) which is rotatably mounted in the respective housing (2), is arranged parallel to the guideway (8) and is drivably coupled to the respective base jaw (11),
the threads (10) worked into the drive spindle (9), through which the torques from the crank are transmitted for the linear displacement of the base jaws (11), should be permanently encapsulated in a watertight and airtight manner irrespective of the position of the base jaws (11) or the drive spindle (9), and on the other hand the adjustment travel (Δs) of the base jaws (11) or clamping jaws (13) should be as large as possible in order to clamp workpieces with configurations that can be completely different without the need for time-consuming and complicated conversion measures. This is achieved in that a right-hand thread and a left-hand thread (10) are worked onto the drive spindle (9) in regions, in that the respective thread (10) of the drive spindle (9) is enclosed or encapsulated by a cover sleeve (21), in that the cover sleeve (21) has a right-hand thread and a left-hand internal thread (22), which are drivably coupled to the respective thread (10) of the drive spindle (9), in that a right-hand and a left-hand external thread (23), which is in engagement with the respective internal thread (12) of the base jaw (11), is worked on to the cover sleeve (21).

A pipe chain system has a chain that is made of a plurality of chain links. Each chain link has a body. The body has a male end and a female end such that the male end matingly engages with the female end of an adjacent chain link. The body has an arcuate underside. The arcuate underside corresponds to a portion of a pipe diameter to which the chain is attached. A pin connection is provided for mating each mating engagement of the male end and the female end of the adjacent chain links such that the chain links are hingedly connected to each other.

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.

The invention relates to a gripping or clamping device having an actuator, including a drive driving the actuator, and at least one jaw that is motion-coupled with the actuator. The actuator includes a spindle having a threaded portion, wherein for the purpose of motion coupling, an active portion meshing the threaded portion is arranged on the jaw side.

A pipe fitting stand for supporting a pipe during a work operation includes a table, and a plurality of legs coupled to the table and movable between a deployed position and a stowed position. The pipe fitting stand additionally includes a vise coupled to the table for supporting a first portion of the pipe, and a support positioned on a side of the table opposite the vise upon which a second portion of the pipe is supported. The support is adjustable relative to the table, thereby adjusting the orientation of the pipe relative to the table.
