AI Technical Summary
Existing drilling devices struggle to provide omnidirectional and uniform clamping force when holding workpieces, causing the workpieces to easily shift or wobble during the drilling process, affecting drilling accuracy and quality.
The multi-step clamping method is adopted. The motor drives the bidirectional screw to move the moving block for initial clamping. Then, the screw rod is turned to move the jaws toward the side wall of the workpiece. The design of ratchet, chuck and T-bar prevents over-clamping and ensures the stability of the workpiece.
It improves the stability of the workpiece during the drilling process, ensures drilling accuracy and quality, prevents workpiece damage, and extends the service life of the device.
