Generally speaking, any device used to quickly, conveniently and safely install a workpiece in any process of the technological process can be called a fixture. A fixture usually consists of a positioning element (to determine the correct position of the workpiece in the fixture), a clamping device, a tool setting and guiding element (to determine the relative position between the tool and the workpiece or to guide the tool direction), a indexing device (to enable the workpiece to complete the processing of several work positions in one installation, including two types: rotary indexing device and linear moving indexing device), a connecting element, and a fixture body (fixture base), etc. For example, welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc., among which machine tool fixtures are the most common and are often simply referred to as fixtures.
