Abstract
The invention relates to a processing technology of a motor rear end cover, which comprises an end cover body, a plurality of installation holes are opened at the corners of the end cover body, a blade slot is arranged in the middle of the end cover body, and the fan The middle part of the blade slot is provided with a perforation for the output shaft of the power supply to pass through, and a plurality of ventilation holes are opened on the side wall of the blade slot, and the outer surface of the end cover body is coated with a zinc layer by a vacuum coating machine. The present invention can reduce the possibility of the end cover being corroded by coating the outer surface of the end cover with a galvanized layer, thereby prolonging the service life of the end cover.
Description
Technical field [0001] The present invention relates to the field of motor manufacturing techniques, and more particularly to a machining process of a rear end cap. Background technique [0002] End cover is a key component in the motor, so the structural design and processing of end caps are important, its material, inner size, outer size, wall thickness, shape, etc. have a direct effect on the operating stability of the motor. . [0003] The prior art can refer to the authorization notice number of Chinese invention patents for CN103516100B, which discloses an insulative end cap comprising an end cap body, and the front end is opened in the front end of the outer surface, and the rear end is opened. The slot is provided with a through hole in the middle of the end cover body; the distance A between the first groove and the end surface of the end cover is 5 mm; the distance B between the rear end surface of the second groove distance end cover is 2 mm; The first groove, the groo...
