[0002] Carbon brushes, also called electric brushes, are widely used as sliding contacts in many electrical devices. The main materials used in carbon brush products are graphite, impregnated graphite, metal, etc. Carbon brushes are devices that transfer energy or signals between the fixed part and the rotating part of a motor or generator or other rotating machinery.
[0003] During the manufacturing process, the carbon brushes may leave some burrs, unevenness or poor surface features. These surface defects may cause friction, wear or poor electrical contact, so the carbon brushes need to be polished. The polishing process is likely to produce a lot of debris, which is easy to adhere to the carbon brushes being processed, thereby affecting the electrical contact between the carbon brush and its contact surface, resulting in increased resistance or poor current transmission.

[0006] Preferably, the driving mechanism includes an electromagnetic guide rail fixedly mounted on the top of the device table, the outer surface of the electromagnetic guide rail is slidably connected to a shift seat, and the outer surface of the shift seat is fixedly connected to a support table. The position of the grinder can be adjusted through the driving mechanism, and the cold air gun can be driven to move synchronously at the same time, so that the cold air gun always sprays airflow towards the grinding area during the grinding process.

[0008] Preferably, the positioning mechanism includes a stepper motor fixedly installed inside the fixed table, and the output end of the stepper motor is fixedly connected to the drive shaft. The airflow spray angle of the cold air gun can be adjusted through the positioning mechanism.

[0009] Preferably, one end of the driving shaft away from the stepping motor is fixedly connected to a driving gear, and the outer surface of the driving gear is meshingly connected to a chain.
[0010] Preferably, one end of the inner side of the chain away from the driving gear is meshedly connected with a driven gear, and the inner surface of the driven gear is fixedly connected to one end of the rotating shaft away from the cold air gun.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The motor carbon brush processing and forming device can timely blow away the debris generated by grinding through the air flow jet of the cold air gun during the grinding process, reducing its residual adhesion on the surface of the carbon brush.

[0019] Through the above technical solution, the device places the carbon brush on the processing table 2 when in use, and the position of the grinder 9 can be adjusted through the driving mechanism to grind different positions on the surface of the carbon brush. During this process, the cold air gun 16 is always facing the grinding position of the grinder 9. After the grinding is completed, the air flow spray angle of the cold air gun 16 is adjusted through the positioning mechanism to clean the debris remaining on the entire surface of the carbon brush.

An electric push rod 8 is fixedly installed on the outer surface of the platform 5, and the output end of the electric push rod 8 is fixedly connected to the top of the fixed platform 7.
[0023] Through the above technical solution, the fixed platform 7 can be pushed by the electric push rod 8, so that the fixed platform 7 slides along the slide rail 6, thereby causing the fixed platform 7 to move in the vertical direction.
[0024] Specifically, the position adjustment mechanism includes a stepper motor 10 fixedly installed inside the fixing platform 7 , and an output end of the stepper motor 10 is fixedly connected to a driving shaft 11 .
[0025] Through the above technical solution, after the stepper motor 10 is turned on, the driving shaft 11 can be driven to rotate, and during this process, the driving gear 12 rotates synchronously therewith.
[0026] Specifically, one end of the driving shaft 11 away from the stepping motor 10 is fixedly connected to the driving gear 12 , and the outer surface of the driving gear 12 is meshedly connected to the chain 13 .
[0027] Through the above technical solution, when the driving gear 12 rotates, the chain 13 meshing with it will be affected by the transmission effect and perform corresponding transmission.

In this process, the airflow of the cold air gun 16 is sprayed The angle is always facing the grinding position of the grinder 9. On the one hand, it can cool the grinding area, and on the other hand, it can blow away the debris generated by grinding to reduce the residual adhesion of the debris on the surface of the carbon brush. After completing the carbon brush grinding operation, the stepper motor 10 can be turned on to drive the drive shaft 11 to rotate, and then the drive gear 12 is linked to rotate.
