Abstract

A high-precision wheel rim burr removing device is composed of a rack, a base, longitudinal guide rails, a longitudinal servo motor, a first ball screw, a longitudinal moving plate, a transverse servo motor, transverse guide rails, a second ball screw and the like. A wheel is initially positioned and clamped by adopting the central hole, then the coaxiality deviation of the center hole and cap sections is eliminated, and the rotating center of the burr part of the outer rim is superposed with the rotating centers of cutters, so that high-precision burr removal is realized. The device has the characteristics of advanced process, stability, high efficiency, high degree of automation and the like.
