Description

[Technical field]

[0001] The invention relates to the field of processing fixtures, in particular to a pneumatic fixture for pipe fittings. [Background technology]

[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 of the process can be called a fixture. When processing pipe fittings, special fixtures are required because the clearance length of the workpiece is longer than the clamping length. When the workpiece is not supported by a fixture, the centrifugal force at the tail during processing will be too large due to its own gravity, causing the pipe fitting to bend. In existing fixtures, bolts are mostly used to fix the workpiece, which is not only inefficient but also easy to damage the pipe fitting. Therefore, it is necessary to propose a pneumatic fixture for pipe fittings. [Summary of the invention]
