AI Technical Summary

Technical Problem

Existing CNC machine tools have difficulty effectively compensating for vertical errors when performing interlocking operations, and existing floating modules can only compensate for horizontal errors.

Method used

A precision compensation mechanism for CNC machine tools with multi-angle fixing function was designed. By combining a rotating base, a driving bevel gear, a transmission bevel gear, a friction plate, a threaded rod, and a limit block, the base can be rotated at multiple angles and precisely fixed, ensuring error compensation in both horizontal and vertical directions.

Benefits of technology

It achieves error compensation for CNC machine tools in multiple directions, improves the accuracy and stability of base rotation, and ensures the machining accuracy of machine tools at multiple angles.
