Description

Technical Field

[0001] The invention relates to the technical field of carbon brush holder assembly, in particular to an assembly device for a carbon brush holder for an automobile. Background Art

[0002] The carbon brush holder is an important component in the motor. Its main function is to apply pressure to the carbon brush in sliding contact with the commutator or collector ring surface through a spring to ensure that the carbon brush can stably conduct current between the fixed body and the rotating body. The carbon brush holder plays a vital role in the motor. No matter how good the characteristics of the carbon brush are, if the brush holder is not suitable, the carbon brush will not only fail to give full play to its excellent characteristics, but also have a great impact on the performance and life of the motor itself; therefore, choosing a suitable carbon brush holder is crucial to ensure the normal operation of the motor and extend its service life.

[0003] The carbon brush holder is mainly composed of a circular frame and a brush box installed on the circular frame. The brush box is used to limit the freedom of movement of the carbon brush, and the brush box is usually fixed to the circular frame by welding, riveting, etc. Usually, the brush boxes are symmetrically distributed on the circular frame. The installation accuracy of the brush box on the circular frame directly affects the installation accuracy of the carbon brush, thereby affecting the operating condition of the motor.

[0004] Publication No. CN102684030B-carbon brush holder assembly equipment can use a driving mechanism and a positioning component to fix the brush box on the brush holder, but the driving mechanism and positioning components are numerous and costly, and it is also not suitable for brush box installation methods such as welding or riveting. Summary of the invention

[0005] In view of this, an object of the present invention is to provide an assembly device for a carbon brush holder for an automobile to solve the above-mentioned problem.

[0006] Based on the above purpose, the present invention provides an assembly device for a carbon brush holder for an automobile, comprising:
