Running-in device of aviation motor brush

Abstract

The invention relates to the field of aviation motor part machining, and concretely relates to a running-in device of an aviation motor brush. The device comprises a base and a machining table, and further comprises a controller, a grinding wheel, a pressing mechanism, a containing mechanism and a cleaning mechanism, the containing mechanism comprises two discharging frames and two swing assemblies, and the pressing mechanism comprises a driving assembly and two pressing plates. The cleaning mechanism comprises a traction assembly, a rotating assembly and a plurality of fans, two supporting plates are symmetrically arranged at the top of the machining table, the fans are symmetrically arranged at the tops of the two supporting plates, the rotating assembly is arranged on the outer wall of the machining table, the traction assembly is arranged between one pressing plate and the rotating assembly, and the driving assembly is electrically connected with the controller. According to the running-in device of the motor brush for aviation, it can be guaranteed that the feeding position is uniform, running-in is uniform, the running-in quality is improved, meanwhile, dust and carbon powder can be rapidly cleaned away before and after running-in, and the finished product quality is improved.

Description

technical field [0001] The invention relates to the field of machining parts of aviation motors, in particular to a running-in device for brushes of aviation motors. Background technique [0002] Brushes are an important component of an electric motor, conducting electrical current between the rotating and stationary parts. Because it is mostly made of graphite, it is also called carbon brush. The brush is mostly assembled on the commutator or slip ring, and is a sliding contact body. It needs to have the characteristics of smoothness, wear resistance and good conductivity. Depending on the application, they are either partially metallic components (copper, silver, molybdenum), or entirely made of metal. [0003] my country's patent application number: CN201610681504.3; publication date: 20191224 discloses a running-in device for motor brushes. In order to ensure the performance of the motor, the brushes need to be run-in after initial processing to ensure the contact be...

AI Technical Summary

Problems solved by technology

[0005] 1. When clamping several brushes, there is no design limit structure, and the feeding is easy to be uneven, so that the clamping positions of several brushes are inconsistent, resulting in uneven grinding

[0006] 2. After several brushes are run-in, it is inconvenient to take because they are stacked layer by layer, resulting in low cutting efficiency

[0007] 3. Since the grinding wheel and several brushes are located inside the brush holder assembly, the toner powder dropped during running-in is easy to adhere to the outer wall of the finished product and inside the device, which is likely to cause pollution of the device and the finished product, reducing product quality
