Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a brush holder pressure tester. Background Art

[0002] The brush holder is a mechanical guide groove that holds and maintains the position of the carbon brush in the brushed motor. It is the component that mounts the carbon brush and keeps it in contact with the sliding surface under pressure.

[0003] The brush holder includes a carbon brush groove and a spring. The carbon brush groove is used to place the carbon brush, and the spring is used to provide pressure to the carbon brush and limit it in the carbon brush groove. At present, there is no special equipment to test the pressure of the brush holder's spring on the carbon brush. If the elastic force of the spring on the carbon brush is too large, the carbon brush will be severely worn; if the elastic force of the spring on the carbon brush is too small, the carbon brush will not contact the sliding surface.

[0004] The inventors have found at least the following problems in the process of implementing this embodiment:

[0005] Currently, there is no equipment specifically for testing the pressure of the spring of the brush holder on the carbon brush, so the carbon brush cannot work well. Utility Model Content

[0006] In order to overcome the problems existing in the above-mentioned background technology, the purpose of the utility model is to provide a brush holder pressure tester to solve the problem that the existing carbon brush cannot work well in the brush holder.

[0007] To achieve its purpose, the utility model adopts the following technical solutions:

[0008] A brush grip pressure tester, comprising: a testing device and a handheld display screen;

[0009] The test device includes a test housing and a pressure sensor;

[0010] The pressure sensor is fixedly installed in the test housing;

[0011] The pressure sensor is connected to a touch pressure plate;

[0012] The touch pad is arranged on one side of the test housing;

[0013] The testing device is electrically connected to the handheld display screen.

[0014] Preferably, the testing device is the same size as the carbon brush.

[0015] Preferably, the test housing is made of stainless steel.

[0016] Preferably, the touch panel is made of rubber.

[0017] Beneficial effects of the utility model:

[0018] The utility model provides a brush holder pressure tester. When it is necessary to test the pressure of the spring on the brush holder on the carbon brush, the carbon brush placed in the carbon brush groove is first taken out, and then the testing device of the tester is placed in the carbon brush groove. Finally, the pressure value of the spring will be detected by the testing device and displayed on the handheld display screen. If the pressures of the springs in several carbon brush grooves on the brush holder are inconsistent, it is necessary to adjust the pressure of the spring to make it consistent, so that the carbon brush can work better in the motor.
