[0002] Tooling, or process equipment, is a general term for various tools used in the manufacturing process. It includes tools / fixtures / moulds / gauges / gauging tools / auxiliary tools / pliers tools / workstation equipment, etc. Tooling is its general abbreviation. A fixture is a process device used to quickly tighten the workpiece during processing so that the machine tool, tool, and workpiece maintain the correct relative position. The use of fixtures is very wide and can significantly improve the efficiency of part preparation. Publication number: CN220278931U discloses a tooling fixture, including a fixture table, the upper surface of which is provided with a conversion mechanism for conveniently changing the processing direction of the workpiece, a mounting table is fixed on the upper surface of the conversion mechanism, and a clamping mechanism is provided on the upper surface of the mounting table for conveniently clamping workpieces of different specifications, and the conversion mechanism includes a fixed block fixed on the upper surface of the fixture table, and a placement groove is provided on the upper surface of the fixed block, and a cylinder is fixed on the inner bottom wall of the placement groove. The tooling fixture is provided with a conversion mechanism. Through the cooperation among the fixed block, placement slot, cylinder, support seat and fixed plate and positioning pins, the support seat can be lifted according to production needs during machine tool processing of the workpiece to facilitate the rotation of the mounting table to change the processing direction. At the same time, the cooperation between the positioning pins and the sockets can locate the position of the mounting table and keep the conversion position accurate. When the tooling fixture is used to clamp the workpiece, especially when clamping irregular parts, the parts on the clamp are prone to move to the sides without the clamp due to the small contact area between the clamp and the parts, which leads to problems affecting the use of the fixture, so it is necessary to improve it.
