When inspecting the inner ring of the bearing, the staff stands on both sides of the processing table 1, places the bearings in the bearing placement slots 7 that do not correspond vertically to the inspection head module 4, and sets the bearings on the outside of the bearing positioning column 8 , after the placement is completed, start the motor 10 to rotate 90°, and the motor 10 rotates 90° to drive the rotating disk 6 to rotate 90° on the processing table 1, so that the bearing placement groove 7 where the bearing is placed is rotated to the bottom of the detection head module 4, and the empty The bearing placement groove 7 rotates to the front of the worker. At this time, the worker continues to place new bearings into the empty bearing placement groove 7. At the same time, the hydraulic rod 3 is started to work. The hydraulic rod 3 begins to stretch and drives the detection head module 4 to descend;

When the detection head module 4 descends, the detection conical head 42 moves downward. The bearing positioning post 8 enters the recessed hole 47 and contacts the top surface of the recessed hole 47, and the detection conical head 42 starts to drive the bearing. The positioning column 8 moves downward, and the bearing positioning column 8 moves downward, driving the connecting plate 17 downward to compress the recovery spring 14, and driving the connecting rod 15 downward, and the connecting rod 15 pulls the two bearing splints 9 to move toward the bearing until the bearing The splint 9 clamps the outer ring of the bearing. At this time, the connecting plate 17 and the bearing positioning post 8 are no longer moving downward. The detection cone head 42 continues to move downward and due to the immobility of the bearing positioning post 8, the detection cone head 42 begins to move upward. Compress the buffer spring. When the detection cone head 42 enters the inner ring of the bearing, the detection slide located at the bottom is blocked above the inner ring and begins to slide upward along the detection ruler groove 45 until the pressure sensor 44 contacts the T-shaped column 41 , the hydraulic rod 3 stops extending, the detection camera 5 starts to take pictures of the position of the detection slider 46, and determines the size of the inner ring of the bearing based on the corresponding reading on the detection ruler groove 45, and then the hydraulic rod 3 contracts, driving the detection head module 4 starts to recover. At the same time, the connecting plate 17 and the bearing positioning column 8 start to recover due to the rebound of the recovery spring 14. The two bearing splints 9 also recover and release the bearing. The motor 10 rotates 90° again, and the tested bearing is aligned with the staff. The new bearing to be inspected moves below the inspection head module 4 to start inspection of the next set of bearings.

In the above operation steps, when the bearing positioning post 8 is no longer moving downward and the bearing splint 9 has clamped the bearing, even if the detection cone head 42 can continue to extend downward into the inner ring of the bearing at this time, it will continue to move downward. , the detection cone head 42 has begun to compress the buffer spring upward. In order to ensure that when the pressure sensor 44 is triggered at this time, the detection cone head 42 completes the detection of the inner ring of the bearing. In actual use, according to the bearings of different sizes , adjust the vertical length of the bearing positioning post 8 to ensure that even if the bearing positioning post 8 is no longer pressed down, when the pressure sensor 44 is triggered, the detection cone head 42 has been pressed down to the deepest position in the bearing inner ring.
