[0023] A magnetic ring wear resistance tester, comprising an equipment box 1, a cabinet door 2 is hinged on one side of the equipment box 1, a display screen 4 is arranged on the end surface of the cabinet door 2, two sets of guide rails 9 are fixedly connected to the upper side of the other side of the equipment box 1, a magnetic ring placement mechanism is installed on the guide rail 9, and the magnetic ring placement mechanism includes a mounting seat 17 that can be slidably arranged on the guide rail 9, a magnetic ring placement platform 18 is fixedly installed on the mounting seat 17, a T-shaped groove with an opening upward is provided on the upper end of the magnetic ring placement platform 18, one end of the guide rail 9 is fixedly connected to the mounting bracket 8, one end of the mounting bracket 8 is fixedly connected to the support plate 3, a driving wheel 6 is arranged at the lower back of the equipment box 1, a sensor 23 is arranged on the outer side of the driving wheel 6, and the driving wheel 6 cooperates with the magnetic ring placement mechanism to form a magnetic ring test structure. The device box 1 has a heat dissipation port 7 on the upper left side, and the heat dissipation port 7 cooperates with the heat dissipation fan 21. The device box 1 has a power transmission hole 5 and an air inlet on the lower side. The inner cavity bottom of the device box 1 has a servo motor 11, and the rotating shaft of the servo motor 11 is fixedly connected to the driving wheel 6. The servo motor 11 has a controller 10, a servo driver 12 and a protection switch 13 on the upper side. The top surface of the device box 1 has a signal light 14, a start button 15, a close button 16 and a heat dissipation fan 21. The controller 10 is electrically connected to the display screen 4, the servo motor 11, the servo driver 12, the protection switch 13, the signal light 14, the start button 15, the close button 16, the heat dissipation fan 21 and the sensor 23.
[0024] Depend on Figure 1-Figure 5 It can be seen that by placing the magnetic ring in a T-shaped slot with an opening upward at the upper end of the magnetic ring placement table 18, the T-shaped slot limits the magnetic ring, and the middle gap on the T-shaped slot allows a section of the arc length of the magnetic ring to be exposed, so that the magnetic ring can achieve a larger contact area.

Then the two ends of the detection line are tied. By twisting the fastening bolts and rotating the adjusting plate 22, the position of the fastening bolts in the U-shaped limiting slots changes, thereby changing the inclination angle of the adjusting plate 22 on the L-shaped connecting plate, changing the contact area between the magnetic ring and the detection line, and enabling the tester to obtain the wear resistance of different areas of the magnetic ring.
