[0024] The positioning mechanism includes a third through slot 16. Two third through slots 16 are provided inside the operating table 1. Second rotating shafts 17 are rotatably installed inside the two third through slots 16 through bearings. A movable block 18 is provided on the outside of the second rotating shaft 17. A guide rod 19 is passed through the inside of the movable block 18. The end of the guide rod 19 is fixedly connected to the inner wall of the third through slot 16. The upper end of the movable block 18 passes through the inside of the third through slot 16 and a movable plate 20 is fixed thereto. A clamping column 21 is fixed to one side of the movable plate 20. The end of the second rotating shaft 17 passes through the inside of the operating table 1 and a first handle 22 is fixed thereto. The second rotating shaft 17 is located on the outside of the two third through slots 16 and is provided with opposite threads. The second rotating shaft 17 is threadedly connected to the movable block 18. The movable block 1 8 is slidably connected to the guide rod 19, and there are two movable blocks 18 and movable plates 20 symmetrically distributed about the central axis of the first rotating shaft 2, and there are two clamping columns 21 symmetrically distributed about the central axis of the movable plate 20. The movable block 18 is slidably connected to the third through groove 16. By rotating the first handle 22 forward or reversely, the two movable plates 20 can be driven to move towards or away from each other, so that the two clamping columns 21 on the left and the two clamping columns 21 on the right can also move towards or away from each other, thereby completing the clamping and fixing of bearing inner rings of different diameters, and at the same time ensuring that the central axis of the bearing inner ring coincides with the central axis of the first rotating shaft 2, which is convenient for rapid positioning of the bearing inner ring.
[0025] The fixing mechanism includes a threaded groove 5, a threaded groove 5 is opened on the inner side of the first through groove 3, and a locking rod 6 is installed on the internal thread of the threaded groove 5.

[0026] Working principle: When using the bearing inner ring detection device, first place the bearing inner ring between the four clamping columns 21, then rotate the first handle 22, and then the first handle 22 drives the second rotating shaft 17 to rotate.

[0027] Then move the outer rod 4, and the outer rod 4 drives the movable column 14 to move until the outer side of the movable column 14 contacts the inner side of the bearing inner ring, and at the same time, move the outer rod 4 with force to compress the spring 10 inside the outer rod 4, and then rotate the locking rod 6. Since the locking rod 6 and the threaded groove 5 are threadedly connected, the end of the locking rod 6 is in close contact with the outer wall of the outer rod 4 to complete the fixation of the outer rod 4. At this time, the pressure sensor 9 is subjected to pressure, and the pressure sensor 9 transmits the pressure to the computer, and then rotates the second handle 23. Then the second handle 23 drives the movable column 14 to rotate around the central axis of the first rotating shaft 2 through the first rotating shaft 2, the first through groove 3, the outer rod 4, the threaded groove 5, the locking rod 6, the groove 7, the spring 10, the inner rod 11 and the fixing ring 13. When the movable column 14 rotates one circle, if the pressure value detected by the pressure sensor 9 does not change, it means that the quality of the bearing inner ring is qualified. When the pressure value detected by the pressure sensor 9 changes, it means that the quality of the bearing inner ring is unqualified.
