[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a fixture. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture. The fixture usually consists of a positioning element (to determine the correct position of the workpiece in the fixture), a clamping device, a tool guiding element (to determine the relative position of the tool and the workpiece or to guide the direction of the tool), an indexing device (to enable the workpiece to complete the processing of several stations in one installation, and there are two types of rotary indexing devices and linear motion indexing devices), connecting elements and a clamping body (fixture base).
