Description

Technical Field

[0001] The invention relates to the technical field of brushless motor housing cover assembly tools, and in particular to a precise and rapid assembly process and device for brushless motor housing cover parts. Background Art

[0002] With the rapid development of industrial automation and intelligent manufacturing, brushless motors have been widely used in electric vehicles, household appliances, industrial automation equipment and other fields due to their advantages such as high efficiency, low noise and long life. The outside of the brushless motor is generally provided with a corresponding protective motor cover. When preparing the brushless motor, it is usually necessary to assemble the motor cover. However, the assembly process of the brushless motor is complicated, especially the assembly of the cover parts, which requires extremely high precision and efficiency.

[0003] Most traditional assembly methods involve manually placing the corresponding brushless motor housing cover on the corresponding assembly workbench for assembly operations. During the specific assembly operation, it is necessary to manually hold or press it with both hands, and then use the corresponding tools for assembly operations. First of all, during the manual holding or pressing process, it is not conducive to freeing up both hands for other operations. In addition, when using tools for auxiliary assembly, the random placement of tools is easy to lose, and searching again will delay time, which is not conducive to accurate and rapid assembly operations, affecting the assembly effect and bringing inconvenience to users. In view of this, we propose a precise and rapid assembly process and device for brushless motor housing cover parts. Summary of the invention
