AI Technical Summary

Technical Problem

Traditional mechanical clamping devices often use rigid, integrated clamping plates with fixed or inconvenient angles, resulting in poor fit when clamping irregularly shaped workpieces. This can lead to suspension and uneven force distribution, affecting machining accuracy.

Method used

It adopts a rotatable circular turntable and clamping mechanism, and realizes synchronous radial movement and angle adjustment of the clamping components through a motor-driven gear and rack transmission system. The clamping angle is fixed by a locking component to ensure clamping stability.

Benefits of technology

It achieves adaptive clamping of irregularly shaped workpieces, improves clamping fit and locking stability, and enhances the accuracy and safety of workpiece processing.
