Background

The machine tool fixture is a device for clamping a workpiece and guiding a cutter on a machine tool, and is specially designed for a certain working procedure of a certain workpiece.

Machine tool fixtures can be classified into the following categories according to specialized classification: 1. and (5) a universal fixture. Universal jigs refer to jigs that have been standardized and can be used to process different workpieces to a certain extent. Such as three-jaw chucks and four-jaw single-action chucks on lathes, flat jaws on milling machines, index heads, and rotary tables. Such fixtures are typically produced by specialized factories and are often provided to users as machine tool accessories. The method has the characteristics of wide adaptability and low production efficiency, and is mainly suitable for single-piece and small-batch production. 2. And (5) a special fixture. The special fixture is a fixture specially designed for a certain working procedure of a certain workpiece. The device has the characteristics of compact structure, rapid, convenient and labor-saving operation, and higher processing precision and production efficiency, but longer design and manufacturing period and higher manufacturing cost. When the product is changed, the clamp will be scrapped as it is no longer usable. The method is only suitable for the production with fixed products and large batch. 3. Universal adjustable clamps and ganged clamps. The fixture is characterized in that part elements of the fixture can be replaced, and part devices can be adjusted to adapt to the machining of different parts. The jigs used for gang processing of similar parts are called gang jigs. Compared with a group of fixtures, the universal adjustable fixture has the advantages that a machining object is not clear, and the application range is wider. 4. And (5) assembling a clamp. The combined clamp is a clamp assembled by a set of prefabricated standard elements and parts according to the processing requirements of parts. The manufacturing method is manufactured by professional factories, and has the characteristics of flexibility, changeability, strong universality, short manufacturing period and repeated use of elements, and is particularly suitable for trial production of new products and single-piece small-batch production. 5. And a follower fixture. A pallet is a fixture used on an automated line. The clamp has the functions of clamping the workpiece, and is integrated with the workpiece, and the clamp is moved from one station to the next station along an automatic line to process different working procedures.
