AI Technical Summary

Technical Problem

When a CNC machine tool is drilling or pulled upwards by other forces, the workpiece is easily dragged upwards and slides, resulting in inaccurate clamping and positioning, which affects the machining accuracy and efficiency.

Method used

The clamping assembly, which includes a slide rail, U-shaped bar, and suction cup, achieves precise positioning and stable clamping of the workpiece through the synergistic action of gear meshing and telescopic springs. Combined with the fine adjustment of the pneumatic telescopic rod, the stability of the workpiece during the processing is ensured.

Benefits of technology

It improves the machining accuracy and efficiency of CNC machine tools, prevents workpiece slippage or deformation, and ensures the stability and precise positioning of workpieces during the machining process.
