[0002] A fixture is a device used to fix the workpiece in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a clamp. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture. It is used in the mechanical manufacturing industry to clamp the sheet metal structure of the automobile. It is necessary to fix the sheet metal structure on the fixture through the clamping device according to the actual working state by rotating the threaded rod and nut on the fixture.
