Such as welding jigs, inspection jigs, assembly jigs, machine jigs, etc. Machine tool fixtures are among the most common and often simply referred to as fixtures. When a workpiece is machined on a machine tool, the workpiece must be assembled (positioned) and clamped (clamped) before machining in order to achieve the requirements of the surface of the workpiece such as the size, geometry, mutual position precision with other surfaces and the like specified in the drawing. The fixture is generally composed of a positioning element (determining the correct position of the workpiece in the fixture), a clamping device, a tool setting guide element (determining the relative position of the tool and the workpiece or guiding the tool direction), an indexing device (enabling the workpiece to finish the machining of a plurality of stations in one installation, including a rotary indexing device and a linear movement indexing device), a connecting element, a fixture body (fixture base) and the like.
