AI Technical Summary

Technical Problem

When machining pulleys with specific inclined surfaces, existing milling equipment struggles to maintain the optimal perpendicularity or engagement angle between the milling cutter axis and the machining surface, resulting in inconsistent machining quality.

Method used

A high-precision milling device was designed. Through a motor-driven precise angle deflection and synchronous feedback module, the cutter head can actively adapt to the workpiece slope at different angles. Combined with a biomimetic cloth layer and a pressure sensor to provide real-time feedback on the pulley status, closed-loop control is achieved.

Benefits of technology

It improves the surface quality and consistency of pulley machining, avoids the reference error caused by repeated workpiece clamping in traditional methods, and is suitable for mass production of high-precision pulleys.

Abstract

The application belongs to the technical field of milling processing, and particularly relates to a high-precision milling device and method for belt wheel processing. In view of the poor fitting effect of a milling cutter of a milling device during processing, the following scheme is proposed, which comprises a bottom table, a lifting seat is arranged above the bottom table, a receiving block is fixedly connected to one side of the lifting seat, and a movable seat is fixedly connected to the other side of the receiving block. The application discloses a high-precision milling device and method for belt wheel processing. The precise angle deflection driven by a motor enables the tool head to actively adapt to the inclined surface of a workpiece at different angles, ensures the optimal direction of the milling force, improves the surface quality, and replaces the cumbersome method of repeatedly disassembling and overturning the workpiece to process different inclined surfaces, thereby eliminating the reference error caused by repeated clamping and fixing of the workpiece, and ensuring the processing symmetry and coaxiality of multiple inclined surfaces on the workpiece.
