Description

Technical Field

[0001] The present invention relates to the technical field of motor shock mounts, and specifically to a post-machining process for motor shock mounts. Background Art

[0002] The motor shock mount is used in the automotive air conditioning system and is the motor shock mount in the radiator fan. The manufacturing of the mount generally includes three production processes: aluminum die-casting, vulcanization, and machining.

[0003] The difficulty of the ordinary processing technology lies in the dimensions of the upper and lower bearing chambers of the product. The traditional vulcanization process cannot meet the dimensional accuracy of the product, affecting the qualified rate of the product. Moreover, the noise of the motor radiator fan during operation is relatively large. As the core component of the air conditioning radiator shock absorption, the shock absorption performance and safety performance of the entire radiator system are not ideal enough, and it is also difficult to meet the production requirements of the automotive industry's processing modular blocks. Summary of the Invention

[0004] The purpose of the present invention is to provide a post-machining process for motor shock mounts to solve the problems of difficult assembly of motor shock mounts, inability to meet high-precision requirements after assembly, and deformation of the bearing chamber installation caused by traditional vulcanization as mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A post-machining process for motor shock mounts, and the steps of the post-machining process for motor shock mounts are as follows:
