The control system can logically process programs specified by control codes or other symbolic instructions, decode them, and express them in coded numbers. They are input into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the action of the machine tool. The parts are automatically processed according to the shape and size required by the drawing. During the processing, the workpiece needs to be clamped by a clamping device. The processing procedures of the workpiece also change with the changes in the processing method, and the clamping device is an accessory used in conjunction with the workpiece processing.

[0003] In the existing workpiece processing process, when the fixture clamps the workpiece and transfers the workpiece, the clamping point is subjected to a large force.
