The invention discloses a device for
grinding burrs on the surface of a rotating shaft of a commercial coil motor. The device comprises a base, groove holes, a first driving motor, a threaded
bushing, bearing seats, clamping threaded couplers, a threaded sleeve, a third driving motor and a
grinding wheel, wherein the groove holes are formed in the base, an output shaft of the first driving motor is vertically upward and connected with a screw rod A, the threaded
bushing is arranged on the screw rod A in a threaded mode, the two sets of bearing seats are fixedly arranged on the upper surface of a
machine table, and the bearing seats are further rotationally provided with the clamping threaded couplers. According to the device, movement and fixation can be freely switched, on the one hand, the stability of the device during production and
processing can be improved, and on the other hand, the situation that universal wheels are scrapped due to the fact that the universal wheels are under stress for a long time can be prevented, and the service life of the universal wheels is prolonged; and meanwhile, omni-directional
grinding can be carried out on the rotating shaft in the rotating process of the rotating shaft, and therefore the burring effect on the rotating shaft can be improved, and the situation that parts of the rotating shaft are too thick or too thin in the
grinding process of the rotating shaft can be effectively avoided.
