[0025] Example:

[0027] Working principle: When the wear resistance detection device is used, the brake pad body 7 is first placed on the pad 14, and then the electric push rod 32 is controlled to extend through the external control end, thereby driving the clamping plate 33 to fix the position of the brake pad body 7, and then the electric telescopic rod 22 is controlled to descend through the control display 51, thereby driving the grinding assembly 4 to descend. When the electric telescopic rod 22 descends to a certain height, the grinding disc 43 contacts the brake pad body 7 and generates a certain degree of extrusion force. Because the bottom of the pressure sensor 53 is connected to the output shaft of the electric telescopic rod 22, the pressure sensor 53 will be subjected to the extrusion force, and the pressure sensor 53 will detect the extrusion force signal The value of the specific squeezing force is transmitted to the control display 51, and the display screen on the control display 51 will display the value of the specific squeezing force. The built-in controller of the control display 51 will control the electric telescopic rod 22 to rise or fall, so as to adjust the squeezing force. Then, the motor 41 is controlled to start through the external control end to drive the grinding disc 43 to grind the brake pad body 7. During this process, the U-shaped protective shell 61 will block the flying sparks to avoid safety hazards. In this way, multiple brake pad bodies 7 can be grinded with the same squeezing force and for the same time. Finally, the brake pad bodies 7 can be compared to obtain the wear resistance of different brake pad bodies 7. It is relatively convenient and practical, and it is worth promoting vigorously.
