[0002] The related art (Announcement No.: CN221038549U) discloses a friction plate wear resistance detection device, including a support frame, and a workbench is arranged at the upper end of the support frame. A placement frame is arranged at the upper end of the workbench, and a rotating hole is arranged in the middle position of the placement frame. A rotating shaft is arranged in the rotating hole, and the rotating shaft is used to support and install the grinding plate and drive the grinding plate to rotate. A moving part is arranged at the upper end of the workbench, and the moving part includes a slide rail, and a slider is slidably connected to the slide rail, and a mounting plate is fixedly connected to the upper end of the slider. A detection component is arranged at the upper end of the moving part, and the detection component includes a detection cutter head.

[0003] In the process of implementing the above embodiments, it is found that there are at least the following problems in the related art:

[0004] In the friction plate wear resistance detection device, after the grinding plate is installed on the rotating shaft, it rotates under the drive of the rotation. The detection cutter head moves under the drive of the mounting plate, so as to contact with the surface of the grinding plate and be polished. After running for a set time, the wear resistance of the grinding plate can be judged according to the wear and damage of the grinding plate. However, the grinding plate will gradually become thinner after friction, and thus separate from the detection cutter head. At this time, the position of the detection cutter head needs to be readjusted. Moreover, as time goes by, when the grinding plate becomes thinner again, the position of the detection cutter head needs to be readjusted. Therefore, the operation is more troublesome.

[0036] Combination Figures 1 to 4 As shown, the embodiment of the present disclosure provides a wear resistance detection device, including a first support plate 10, an optical axis 20, a second support plate 30, a third support plate 40, a rotating shaft 50, a driving member 60, a friction block 70, a first fixing ring 80 and an electric telescopic rod 90. The first support plate 10 is used to support the entire device. The optical axis 20 is mounted on the first support plate 10, and is used to support and install the slidable second support plate 30 and the third support plate 40. The second support plate 30 is slidably mounted on the optical axis 20 and can slide along the axial direction of the optical axis 20. The third support plate 40 is slidably mounted on the optical axis 20 and can also slide along the axial direction of the optical axis 20. Along the height direction of the optical axis 20, the third support plate 40, the second support plate 30 and the first support plate 10 are arranged in sequence from top to bottom. The rotating shaft 50 is rotatably arranged on the second support plate 30 along the height direction of the optical axis 20, and can rotate relative to the second support plate 30. The top of the rotating shaft 50 is used to install the grinding disc and drive the grinding disc to rotate. The driving member 60 is installed between the second support plate 30 and the bottom end of the rotating shaft 50, and is used to provide a driving force to drive the rotating shaft 50 to rotate relative to the second support plate 30. The friction block 70 is installed on the bottom surface of the third support plate 40 and is directly opposite to the grinding disc, and is used to abut against the surface of the grinding disc. The first fixing ring 80 is installed on the optical axis 20 and is located between the third support plate 40 and the second support plate 30, and is used to limit the lowest position of the second support plate 30. The electric telescopic rod 90 is installed between the opposite surfaces of the first support plate 10 and the second support plate 30 along the height direction of the optical axis 20, and is used to provide a driving force to drive the second support plate 30 to move along the axial direction of the optical axis 20. Among them, when the moving end of the electric telescopic rod 90 is extended, the grinding disc rises until it abuts against the friction block 70, and when the moving end of the electric telescopic rod 90 is retracted, the grinding disc descends until it is separated from the friction block 70.

[0037] The embodiment of the present disclosure provides a wear resistance detection device, which controls the mobile end of the electric telescopic rod 90 to extend, so as to drive the second support plate 30 to rise, and finally drive the grinding disc installed on the rotating shaft 50 to rise, until it contacts the friction block 70, and then controls the driving member 60 to work, so as to drive the rotating shaft 50 to rotate, and then drive the grinding disc to rotate. In addition, the pressure value can be changed by placing a counterweight on the top surface of the third support plate 40, thereby changing the friction force. After the set time is run, the mobile end of the electric telescopic rod 90 is controlled to retract, so as to drive the second support plate 30 to descend, and finally drive the grinding disc installed on the rotating shaft 50 to descend, until it contacts the friction block 70. Then, the driving member 60 is controlled to stop the grinding disc from rotating, so as to disassemble the grinding disc, and judge the wear resistance of the grinding disc according to the wear and damage of the grinding disc. During the whole detection process, when the grinding disc is worn and thinned, under the action of gravity, the friction block 70 will always be in contact with the grinding disc, without the need to adjust the position, which is simple and convenient, and easy to detect.

[0038] Optionally, combined Figure 1 , Figure 3 and Figure 4 As shown, the driving member 60 includes a driving motor 61, a driving pulley, a driven pulley and a belt 62. The axis of the rotating end of the driving motor 61 is parallel to the axis of the rotating shaft 50, and is used to provide driving force. The driving pulley is installed at the rotating end of the driving motor 61, and rotates under the drive of the driving motor 61. The driven pulley is installed at the bottom end of the rotating shaft 50, and is used to drive the rotating shaft 50 to rotate. The belt 62 is installed between the driving pulley and the driven pulley, and is used to transmit the driving force. Among them, the diameter size of the driving pulley is smaller than the diameter size of the driven pulley.

[0039] In the disclosed embodiment, the driving motor 61 is controlled to work, so as to drive the driving pulley to rotate. The belt 62 can drive the driven pulley to rotate, which in turn drives the rotating shaft 50 to rotate, and finally drives the grinding disc to rotate. In addition, the design that the diameter of the driving pulley is smaller than the diameter of the driven pulley can play a role in reducing the rotation speed.

[0040] Optionally, combined Figure 1 , Figure 3 and Figure 4 As shown, the driving member 60 further includes a support rod 63 and a motor mounting plate 64. The support rod 63 is mounted on the bottom surface of the second support plate 30 along the height direction of the optical axis 20.

The motor mounting plate 64 is used to support and install the drive motor 61, thereby determining the position of the drive motor 61. In addition, the design of the drive motor 61 being located below the second support plate 30 can avoid interference with the grinding disc.

The backing plate 100, the grinding disc and the pressing plate 110 are axially fixed by the nut 120 and the shoulder of the rotating shaft 50. In addition, the backing plate 100 is designed with a larger diameter size, which can stably support the grinding disc to prevent the grinding disc from bending and deforming after contacting the friction block 70. The pressing plate 110 is designed with a smaller diameter size to ensure that the surface of the grinding disc can contact the friction block 70, so as to perform wear resistance testing.
