[0025] The wear resistance detection component 4 includes a rotating head 401 arranged above the fixed frame 1, the bottom end of the rotating head 401 is coaxially connected to the output shaft of the motor 402, the motor 402 is fixedly installed on the top of the bottom frame 2, a friction ring 404 is installed on the outer side of the rotating head 401, and a sliding groove 403 is opened at an equal angle on the outer side of the rotating head 401, and the top of the sliding groove 403 penetrates to the top of the rotating head 401, and a sliding block 405 is installed at an equal angle on the inner wall of the friction ring 404, the sliding block 405 is slidably connected to the sliding groove 403, the bottom wall of the sliding block 405 is tightly attached to the inner bottom wall of the sliding groove 403, and a screw groove 406 is opened on the side of the sliding groove 403 away from the friction ring 404. 406 is located above the sliding block 405, and the internal thread of the screw groove 406 is installed with a limiting bolt 407. The limiting bolt 407 is used to limit the top of the sliding block 405. During operation, the sliding block 405 on the inner wall of the friction ring 404 is slidably connected with the sliding groove 403 on the outer wall of the rotating head 401. When the limiting bolt 407 is unscrewed, the friction ring 404 can be disassembled and installed, thereby facilitating the replacement of the friction ring 404 and improving the accuracy of the wear resistance detection of the ceramic ball. At the same time, the top wall and bottom wall of the sliding block 405 are limited by the limiting bolt 407 and the inner bottom wall of the sliding groove 403 respectively, to ensure the stability of the friction ring 404 during detection.

[0026] The clamping detection component 5 includes a fixing seat 501 installed at an equal angle on the top of the fixing frame 1, the fixing seat 501 is arranged at an equal angle on the outside of the rotating head 401, a slide groove 502 is provided inside the fixing seat 501, a slider 503 is slidably installed inside the slide groove 502, a mounting frame 504 is installed on the top of the slider 503, a spring 505 is installed on the side of the slider 503 away from the rotating head 401, one end of the spring 505 is fixedly connected to the inner wall of the end of the slide groove 502 away from the rotating head 401, a magnetic block 506 is installed on the side of the slider 503 away from the rotating head 401, an electromagnet 507 is fixedly installed on the inner wall of the end of the slide groove 502 away from the rotating head 401, the electromagnet 507 is externally connected to the power supply, the electromagnet 507 is magnetically connected to the magnetic block 506, and the mounting frame 504 is installed on the top of the slider 503. An installation groove 508 is provided at one end close to the rotating head 401, and a ceramic ball is placed inside the installation groove 508. A screw barrel 509 is installed at an equal angle on the outside of the installation groove 508, and a clamping bolt 510 is installed on the internal thread of the screw barrel 509. The end of each clamping bolt 510 is tightly attached to the outer wall of the ceramic ball. During operation, after the ceramic ball is installed in the set installation groove 508, the ceramic ball is tightly attached to the outer wall of the friction ring 404. The motor 402 is turned on to make the friction ring 404 rotate and continuously generate friction with the ceramic ball, thereby facilitating the wear resistance detection of the ceramic ball. At the same time, during the detection, the electromagnet 507 is energized to generate a repulsive force on the magnetic block 506, so that the ceramic ball can always remain in close contact with the outer wall of the friction ring 404, thereby improving the accuracy of the wear resistance detection of the ceramic ball.

[0027] Working principle: When working, first install the ceramic ball to be tested inside the mounting groove 508 at the end of each mounting frame 504, and then tighten the clamping bolt 510. Since the clamping bolt 510 is threadedly connected with the screw barrel 509, the clamping bolt 510 moves toward the ceramic ball, so that the end of each clamping bolt 510 is in close contact with the ceramic ball, thereby fixing the ceramic ball;

[0028] The electromagnet 507 is energized to generate a repulsive force on the magnetic block 506, thereby pushing the mounting frame 504 to move toward the rotating head 401, so that the ceramic ball and the outer wall of the friction ring 404 are closely attached, and the motor 402 is turned on to rotate the rotating head 401, thereby driving the friction ring 404 to rotate, so that the outer wall of the friction ring 404 and the ceramic ball are constantly rubbed. After a certain period of friction, the electromagnet 507 is powered off, the motor 402 is stopped, and the ceramic ball is removed to observe the wear of the ceramic ball, thereby testing the wear resistance of the ceramic ball;

[0029] When the friction ring 404 has been used for a long time, the limiting bolt 407 in the screw groove 406 is unscrewed, so that the limiting bolt 407 on the top of the sliding block 405 disappears. At this time, the friction ring 404 is taken out and replaced with a new friction ring 404, and the limiting bolt 407 is screwed back into the screw groove 406 to limit the friction ring 404 and ensure the detection stability.
