The mounting frame 2 is connected to the upper right side of the top of the frame 1 by bolts. The upper part of the mounting frame 2 is rotatably connected to the rotating shaft 3. The right end of the rotating shaft 3 is connected to the mounting disc 4. The motor 5 is connected to the upper left side of the top of the frame 1 by bolts. The torque sensor 6 is connected to the middle of the top of the frame 1. The left end of the rotating shaft 3 is connected to the right side of the torque sensor 6. The output shaft of the motor 5 is connected to the left side of the torque sensor 6. The connecting plate 7 is connected to the upper right side of the frame 1 by bolts. The vision sensors 8 are connected to both the left and right sides of the upper rear side of the connecting plate 7. The display 9 is connected to the upper right front side of the top of the frame 1. The controller 10 is connected to the upper left front side of the top of the frame 1. The torque sensor 6, the vision sensor 8, and the display 9 are all electrically connected to the controller 10. The friction mechanism is used to friction the disc brake.

[0020] As Figure 1 、 Figure 3 and Figure 4 shown, the friction mechanism includes a mounting plate 11, a housing 12, a sliding frame 13, a friction plate 14, and a pushing component. The mounting plate 11 is connected to the upper right rear part of the frame 1 by bolts. The housing 12 is connected to the front side of the mounting plate 11. The sliding frames 13 are slidably connected to both the left and right sides of the housing 12. The friction plates 14 are connected to the sides of the two sliding frames 13 that are close to each other. The pushing component is used to push the sliding frame 13 to make the friction plate 14 contact the disc brake.

[0021] As Figure 1 and Figure 3 shown, the pushing component includes an electric push rod 15, a mounting rod 16, and a wedge plate 17. The electric push rod 15 is connected to the rear side of the mounting plate 11 by bolts. The front end of the telescopic rod of the electric push rod 15 is connected to the mounting rod 16. The wedge plates 17 are connected to both the left and right ends of the mounting rod 16.

[0022] As Figure 1 shown, it further includes a connecting frame 18, a support plate 19, and a lead screw 20. The connecting frame 18 is connected to the lower right side of the frame 1 by bolts. The support plate 19 is slidably connected to the top of the connecting frame 18. The lead screw 20 is rotatably connected to the top of the connecting frame 18. The lead screw 20 and the support plate 19 are threadedly connected.

[0023] As Figure 3As shown in the figure, it further includes a guide sleeve 21. Guide sleeves 21 are connected to the upper part of the mounting plate 11 on both the left and right sides. The wedge-shaped plate 17 is slidably connected to the guide sleeve 21.

[0024] As Figure 3 As shown in the figure, it further includes rollers 22. Rollers 22 are rotatably connected to the mutually remote sides of the two sliding frames 13.

[0025] The tester places the disc brake between the two friction plates 14 from top to bottom. The support plate 19 supports the disc brake, which facilitates the tester to install the disc brake on the mounting disc 4. After the disc brake is installed, the screw rod 20 is rotated. The screw rod 20 drives the support plate 19 to move downward, so that the support plate 19 is separated from the disc brake, avoiding friction between the disc brake and the support plate 19. At this time, the disc brake is located between the two vision sensors 8. The telescopic rod of the electric push rod 15 is extended to drive the mounting rod 16 and the wedge-shaped plate 17 to move forward. The wedge-shaped plate 17 pushes the sliding frame 13, so that the two sliding frames 13 move towards each other, and thus the two friction plates 14 move towards each other. The two friction plates 14 are respectively in contact with the left and right sides of the disc brake. The guide sleeve 21 can guide the wedge-shaped plate 17 to make the movement of the wedge-shaped plate 17 smoother. The roller 22 can reduce the frictional force generated when the wedge-shaped plate 17 pushes the sliding frame 13, making the movement of the wedge-shaped plate 17 smoother. The motor 5 is started to drive the rotating shaft 3 and the mounting disc 4 to rotate, thereby driving the disc brake to rotate. The friction plate 14 frictions the disc brake, thereby performing wear resistance detection on the disc brake. The vision sensor 8 detects the abrasion marks on the disc brake and transmits the detected data to the controller 10. The controller 10 displays the data on the display 9, enabling the tester to more intuitively see the wear resistance performance of the disc brake and making the detection result more accurate. The torque sensor 6 can detect the torsional moment of the output shaft of the motor 5 and transmit the detected data to the controller 10. The controller 10 displays the data on the display 9. As time passes, the abrasion marks on the disc brake become more and more obvious, the rotational speed of the output shaft of the motor 5 becomes higher and higher, and the torsional moment becomes smaller and smaller. The wear resistance performance of the disc brake can be comprehensively analyzed based on the abrasion marks detected by the vision sensor 8 and the torsional moment detected by the torque sensor 6 to improve the detection accuracy. After the output shaft of the motor 5 rotates for a certain time, it stops. The tester can understand the wear resistance performance of the disc brake through the data on the display 9.
