AI Technical Summary
Existing multi-workpiece synchronous clamping devices have difficulty maintaining consistency when adjusting the spacing between clamping devices, and the process of changing clamps is cumbersome, affecting processing accuracy and production efficiency.
By employing a reverse thread design on the threaded rod and a coordinated action of the slider, along with a locking tongue, limit groove, and spring structure, the spacing between the clamping components can be adjusted synchronously and replaced quickly.
Ensure consistent clamping spacing, reduce machining errors, improve positioning accuracy, shorten fixture changeover time, and enhance production line flexibility and efficiency.
