Deflection coil magnet ring polishing device

The invention discloses a deflection coil magnet ring polishing device. The deflection coil magnet ring polishing device comprises a workbench. The workbench is provided with a rotational rotary table. The rotary table is driven by a first motor. Multiple through holes are formed in the edge of the rotary table annularly. An upper polishing device is arranged over the through holes; a lower polishing device is arranged under the through holes; the upper polishing device and the lower polishing device are of the same structure and are symmetrical with respect to the rotary table. The upper polishing device comprises a first rotary shaft rotationally arranged on the workbench. Two connection rods are fixed to the bottom of the first rotary shaft and are each provided with a rotational bristle brush wheel, and the bristle brush wheels are driven by the first motor. The upper polishing device and the lower polishing device are driven by a drive device. Automatic polishing of deflection coil magnet rings arranged in the through holes of the rotary table is achieved, labor intensity is relieved, the working efficiency is improved, and the deflection coil magnet ring polishing device is very practical.
