Motor end cover fixed by positioning pin and fixing method

Abstract

The invention relates to a motor end cover fixed by positioning pins, which comprises a motor body, the left side and the right side of the motor body are fixedly connected with mounting bins, the outer sides of the two mounting bins are provided with mounting mechanisms, and the interior of each mounting mechanism is fixedly connected with three positioning columns; the mounting mechanism comprises an end cover bin, an adjusting assembly and an inserting assembly are arranged in the end cover bin, the adjusting assembly comprises three studs which are movably connected with the side, away from the motor body, of the end cover bin, and the outer sides of the three studs are all in threaded connection with moving columns; and extrusion balls are fixedly connected to the sides, close to the motor body, of the three moving columns, a fixing ring is fixedly connected to the inner circumferential wall of the end cover bin, and a gear ring is movably connected to the inner circumferential wall of the fixing ring. According to the motor end cover fixed by the positioning pins and the fixing method, the motor body and the end cover bin are mounted and positioned quickly through the cooperation of the positioning columns and the positioning grooves.

Description

technical field [0001] The invention relates to the technical field of motor end covers, in particular to a motor end cover fixed by positioning pins and a fixing method. Background technique [0002] The end cover is a cover installed on the outside of the motor and other casings, commonly known as "end cover". The existing industrial fields, including the field of electric vehicles, require a large number of motors. The traditional motor assembly method is mainly through screws. The end cover The traditional screw motor assembly operation is to pass the screw through the hole of the end cover, and put on the flat washer, spring washer and nut. The dimensions of these four parts are relatively small, and it is extremely difficult to assemble the motor, and Each set of screws, flat washers, spring washers and nuts needs to be tightened with an electric wrench, because it needs to be tightened manually by a group, and the force is inconsistent, so the installation accuracy ca...
