[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, input them to the CNC device through an information carrier, and after calculation and processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and size required by the drawings. When CNC machine tools are machining products, they need to be clamped. However, existing clamping devices have poor overall flexibility and cannot adapt to different types of products, thus causing inconvenience to users. Therefore, we propose a workpiece clamping device for CNC machine tools. Utility Model Content
