Magnetic ring double-sided chamfering device and using method thereof

The invention discloses a magnetic ring double-sided chamfering device and a using method thereof. The magnetic ring double-sided chamfering device comprises a magnetic ring supporting base and a rack, wherein an inverted hydraulic cylinder is arranged at the top of the rack, a motor mounting base is fixed to the output end of the hydraulic cylinder through bolts, motors are fixed to the motor mounting base, and chamfering wheels are arranged on output shafts of the motors; and supporting plates are welded to the side face of the magnetic ring supporting base at equal intervals, ejector rods are horizontally arranged on the supporting plates, and one ends of the ejector rods penetrate into the interior of the magnetic ring supporting base and are provided with supporting rollers through roller frames. According to the magnetic ring double-sided chamfering device and the using method thereof, the motors drive the two chamfering wheels to rotate on the upper end face and the lower end face of a magnetic ring in
