Motor positioning and mounting structure, motor and household appliances

Abstract

The invention provides a motor positioning and mounting structure, a motor and household appliances. The motor positioning and mounting structure comprises a motor housing and a bracket, wherein one of the motor housing and the bracket is provided with a guide protrusion, a positioning protrusion and a screw hole, and the positioning protrusion is connected with an extended start end of the guideprotrusion. The other of the motor housing and the bracket is provided with a guide groove, a positioning groove, a first through hole and an insertion opening, and the insertion opening, the positioning groove and the guide groove are communicated along the first direction. On the projection in the first direction, the area of the positioning protrusion is larger than the area of the guide protrusion, and the area of the positioning groove is larger than the area of the guide groove. The guide protrusion is inserted into the guide groove, the positioning protrusion is inserted into the positioning groove, and the first bolt is fitted with the screw hole through the first through hole. The setting of pre-positioning structure makes the bolt hole alignment fast and accurate, the machining difficulty is reduced, the machining efficiency is improved, the installation accuracy is improved, and the problem of structural appearance defects is solved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor positioning and installation structure, a motor with the motor positioning and installation structure, and a household appliance with the motor. Background technique [0002] In an existing washing machine, the motor is installed in the washing machine through a bracket, for example, the housing of the motor is fixed inside the housing of the washing machine through the bracket. The bracket is provided with through holes, and the motor housing is provided with screw holes. After the bolts pass through the through holes of the bracket, they are locked and matched with the screw holes of the motor housing, thereby realizing the installation between the bracket and the motor housing. [0003] The problem with the existing installation method between the bracket and the motor casing is that there is no pre-positioning between the bracket and the motor casing, it is difficult f...

AI Technical Summary

Problems solved by technology

[0003] The problem with the existing installation method between the bracket and the motor casing is that there is no pre-positioning between the bracket and the motor casing, it is difficult for the screws to align with the threaded holes, and it is easy to scratch the ends of the threaded holes, which brings inconvenience to processing , low production efficiency and other issues, and the inaccurate installation position will cause defects in the appearance of the motor
