[0024] The mounting frames 2 are used to mount two groups of hydraulic cylinders 3. The hydraulic cylinders 3 are used to adjust the height of the adjusting discs 4. The chute 5 is used to mount the slide bars 6 and limit the moving track of the second sliders 14. By driving the first motor 8 to drive the threaded rod 9 to rotate, while the threaded rod 9 rotates, it drives the first slider 10 to move up and down. The first slider 10 drives the connecting rod 12 to move through the first connecting piece 11. The connecting rod 12 drives the second slider 14 to move through the second connecting piece 13. Drive the second motor 17 to drive the rotating rod 18 to rotate. While the rotating rod 18 rotates, it drives the L-shaped rods 19 and the clamping rings 20 to rotate. The clamping rings 20 drive the clamped and fixed bearing to be ground.
[0025] Refer to Figure 1 , Figure 2 and Figure 3 , the bottoms of the second sliders 14 are all fixedly connected with telescopic rods 15. The output ends of the telescopic rods 15 are all fixedly connected with grinding rods 16. Moving tubes 22 are fixedly connected to the outsides of the clamping rings 20.
