[0002] A CNC machine tool is an automated tool whose movements are controlled by a computer control system. It can automatically complete the machining operations of a workpiece according to a pre-set program, and is characterized by high efficiency, precision, and stability.

[0003] Traditional clamping devices mostly rely on manual operation, which is not only inefficient but also makes it difficult to precisely control the clamping force. During the machining process, human factors, such as differences in operator experience and fatigue levels, can easily lead to unstable clamping force, thus affecting the machining accuracy of the workpiece.

[0004] Furthermore, some existing automatic clamping devices are complex in structure, expensive, and difficult to maintain. Their complex mechanical structure and electrical control system not only increase the purchase cost of the equipment, but also require a lot of time and manpower for repair and debugging in daily use, seriously affecting production efficiency.
