[0062] Working principle: firstly, when the load force of the bearing is measured and detected by using the load measuring device for bearing machining, the inner ring of the bearing to be detected is sleeved on the support shaft 18. The double-shaft motor 23 works to drive the threaded rod 24 to rotate. When the threaded rod 24 rotates, the sliding block 25 moves. When the sliding block 25 moves, the connecting shaft 26 moves. The connecting shaft 26 is guided by the guide ring 27 to move stably. The connecting shaft 26 moves to push the arc-shaped plate 22 to move stably.

Then the rotating ring 28 and the support shaft 18 are temporarily fixed and connected. When the support shaft 18 rotates, the rotating ring 28 rotates. When the rotating ring 28 rotates, the scraper 30 rotates to remove the splashing debris in the annular groove 14. The scraper 30 pushes the splashing debris into the discharge chute 31. The discharge chute 31 is inclined to make the splashing debris slide into the support groove 32. Then the splashing debris falls into the waste chute 33 for storage. The purpose of automatically storing the splashing debris during the test is achieved. It is not easy to clean the splashing debris.
