An assembly for immobilizing a chainsaw that includes a platform. The platform having a proximal end and a distal end, and a top surface. The assembly having an upstanding anchor hook and a clamp coupled to the platform for immobilizing the chainsaw. The upstanding anchor hook is configured to receive a front handle of the chainsaw and the clamp is configured to receive a rear handle of the chainsaw, such as to restrict the horizontal and vertical movement of the chainsaw.

A two-station self-centering vise to hold a pair of work pieces is described. The pieces are held in place against a centered fixed jaw, being clamped against the centered fixed jaw by a pair of movable jaws located on either side of the centered jaw and that simultaneously move toward or away from the centered jaw on actuation of a lead screw. The vise may be converted to a single station vise by removable of the fixed center jaw. A spring loaded, adjustable, friction pad attached to the base of one of the two movable jaws enables temporary clamping of a first work piece while the second workpiece is being installed and once both workpieces are in place the lead screw is turned further to securely and accurately hold the workpieces in between the movable jaws and the fixed central jaw.

A clamp support system including a support rack having a pair of first sides and a pair of second sides that interlockingly engage each other. Slots are defined in each of the first sides and slots in the opposed and parallel first sides are aligned. One or more clamps are supported by the support rack. A bar of each clamp is received in a pair of aligned slots in the first sides. Each clamp includes a first jaw and a second jaw operatively engaged with the bar. A workpiece is positioned so that the first jaw of each clamp contacts a first side of the workpiece and the second jaw of each clamp contacts a second side. The first and second jaws are moved relative to each other to clamp the workpiece therebetween.

A vice jaw assembly includes a unitary body that has a top side, a bottom side, a front side, a rear side, a first lateral side and a second lateral side. The top side has an elongated channel therein spaced from the front side and the rear side and defined by a bottom wall, a first lateral wall and a second lateral wall. The bottom wall has a plurality of first wells extending therein each engageable with a male coupler. The bottom wall has a plurality of second wells extending therein each engageable with a male coupler. Each of the second wells is centered within one of a plurality of annular depressions. Each of the annular depressions extends into the bottom wall and has a circular shape. The annular depressions each extend into the first lateral wall such that the lateral wall includes a plurality of semi-cylindrical grooves therein.

An automated vise is disclosed. A gross moveable jaw drive has a stroke longer than the stroke of a fine moveable jaw drive. With this construction, the gross moveable jaw drive can be utilized to actuate the one or more moveable jaws of the vise over a distance greater than the fine moveable jaw drive stroke to a position in which actuation of the fine moveable jaw drive is capable of positioning the one or more moveable jaws in a clamp position to apply pressure to hold the workpiece for machining by, e.g., a CNC machine. In this way, the automated vise can account for workpieces of differing size.

A jig structure for assembling a high frequency connector includes a base on which a rotatable seat is provided, and the surface area of the rotatable seat is smaller than the base. A fixed table is provided on the rotatable seat. The fixed table further includes a first table, and an adjusting rod and a plurality of guide rods are provided on the first table. A plurality of assembly tables are provided on the adjusting rod and the guide rods. The assembly tables are correspondingly disposed, and their movement is controlled by the adjusting rod. A first assembly table and a second assembly table are provided on both sides of the fixed table. The first assembly table has movements along X-axis and Y-axis, and the second assembly stage has movements along Y-axis, thereby corresponding to the relative position of the assembly table and the fixed table so as to quickly place the circuit boards and connectors to be assemble.

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 tooling base that is an improvement over current designs in the form of simplified number of parts, easier manufacturing of parts and that can be actuated for clamping and releasing a tooling fixture by pneumatic, other computer controlled means as well as manually is described. The tooling base uses clamping fixtures that are spring loaded to press cleats into recesses on alignment studs that locate and hold any variety of tooling fixtures to the base.

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 workpiece holder device for workpieces to be machined on multiple sides, wherein the workpiece can be held axially and radially relative to the first axis between a first workpiece holder, operatively connected to at least one support spindle of the workpiece holder device and rotatable about the first axis, and at least one second workpiece holder, operatively connected to at least one drive spindle of the workpiece holder device and rotatable about the first axis, by force locking by means of a clamping force which can be built up in the manner of a vice between the first workpiece holder and the second workpiece holder in the axial direction of the first axis and acting on the opposite sides of the workpiece.
