Fixture is a device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position to accept construction or testing. In a broad sense, any process in the process is used to install the workpiece quickly, conveniently and safely. The devices can be called fixtures. The types of fixtures can be divided into universal fixtures, special fixtures, adjustable fixtures and combined fixtures. The fixtures generally have the function of positioning and clamping the workpiece, making the workpiece processing easier. To a certain extent, the quality of fixture design determines the overall quality of the processed workpiece. Although the design of machine tool fixtures has been developed for a long time, at present, there are still various problems in the fixtures designed in our country, such as positioning Inaccurate, the operation of clamping and unloading the workpiece is complicated, the clamping force of the clamping device cannot effectively fix the workpiece, it is easy to make the workpiece deviate from the processing position during processing, the service life is short, and the processing efficiency is not high.
