A workholding apparatus for components having complex geometries or surfaces, which components are difficult constrain for the purpose of inspection, addresses the problem of adequately constraining such components in a convenient and cost-effective manner so that they do not move during inspection, while also making all or most critical features accessible to the inspection instruments being used. A method teaches how to eliminate setup changes between different components through the use of inexpensive modular attachments. These attachments are in the form of a single piece thermoplastic part which is affixed to each component having also reference features that can be interlocked into a common base fixture for more efficient inspection operations.

A fitting (20) for holding a flat component (1), including radial support stops (2; 3), and a chamber (40) bordered by jaws (21; 22) including clamping surfaces (310; 320) for holding the component (1), open on one side by a recess (41; 42) to perform an operation on the component (1), this fitting (20) is deformable between an open position and a closed position around the component (1) tightened by said jaws (21; 22) subjected to a closing force exerted by manoeuvring means arranged to bring these jaws (21; 22) closer to each other.

A holding device (100) for a blank (200), having a first holding element (101-1) for inserting the blank (200); and a second holding element (101-2) for clamping the blank (200), which is lockable to the first holding element (101-1) by a rotational movement.

A holding attachment includes a holding portion with a round or substantially round columnar hole shape in which a held portion of a material before cutting is inserted and a mounting portion that is mounted on a work mount of a cutting machine. The mounting portion includes at least one pin that is inserted to at least one pin insertion hole provided in the work mount and at least one engagement portion that is engaged with at least one rotation stopper provided in the work mount. A position reference portion of the material before cutting is recessed from a round or substantially round columnar outer peripheral surface of the held portion. The holding portion includes a fitting portion fit to the position reference portion of the material before cutting.

A clamp bench for key duplicating machines, comprising a fixed component, a first rotary component, a second rotary component and a slide base; the fixed component comprises a first fixed component and a second fixed component, the first fixed component is used to hold the master key in place and the second fixed component is used to hold the key blank in place; the first rotary component, the first fixed component and the second fixed component are rigidly connected to the first plane of the first rotary component, the second rotary component forms a rotary connection with the second plane of the first rotary component. Using the clamp bench, the user can press and rotate the handle with one hand to perform composite rotary feeding of the duplicated key along two different axial lines around the rotary axis and the slide base, completing the processing of the key with bevel tooth.

A blank holder and a blank are provided, the blank holder having a receiving area for a substantially disc-shaped blank, the receiving area being curved. The receiving area forms a straight, circular or part-circular or arc-shaped form-fitting profile. The blank has a matching guide shell which can be inserted or turned into the form-fitting profile.

A machining tool assembly is provided for machining a blank to form a firearm lower receiver. The assembly includes a pair of side plates positionable on opposed sides of the blank to capture the blank therebetween. A template plate having a template aperture is adapted to be removeably attachable to the side plates. The template aperture is aligned with a top surface of the blank and is adapted for machining a cavity within the blank having a peripheral contour complimentary to a peripheral contour of the template aperture. A centering mechanism is adapted to be removeably attachable to the template plate, with the centering mechanism including an opening aligned with a corresponding void formed on the blank to align the blank with the template plate.

A technological equipment for tank track moving supports is provided and includes a zero-point positioning system, a workpiece identifying system and a clamping apparatus in cooperation with the moving support, the clamping apparatus includes a tooling plate, a clamp and a pressing device for pressing the moving support are detachably connected to the tooling plate, the moving support is located between the clamp and the pressing device, and the pressing device abuts against the moving support. The moving support with different shapes and sizes can be clamped, and the clamping is stable and convenient to operate.

A tag cassette assembly for use in connection with an engraving process carried out in an engraving machine includes a single piece cassette body of plastic material, the cassette body including a first major side and a second major side and a periphery formed by minor edges; a tag secured in a capture space of the cassette body; wherein the cassette first major side is configured to provide access to a first side of the tag to facilitate engraving and the second major side is configured to provide access to a second side of the tag to facilitate engraving.

A gun smith platform includes a top plate. The top plate has a tool hole centrally disposed on the top plate that extends through the top plate through which a work piece attached to a work tool mounted to a bottom side of the top plate may extend, a plurality of alignment holes extending in a linear pattern from the tool hole, the alignment holes configured to receive alignment pins, at least one row of threaded mounting holes disposed parallel to the linear pattern of alignment holes, and a recessed track disposed parallel to the at least one row of threaded mounting holes. Four legs are attached to and supporting the top plate.
