The support plate 83 is fixedly connected to the tops of the two hydraulic telescopic rods 82 in each group.

[0059] The working principle of a driving shaft processing and fixing mechanism provided by the present utility model is as follows:

[0060] First, start the second driving motor 53 to drive the rotation of the threaded rod in the second slide rail 51. The second moving seat 52 drives the front and rear moving component 6 to move left and right to a suitable position. Then, start the third driving motor 63 to drive the rotation of the driving threaded rod 61. The third moving seat 62 drives the connecting slide rod 72 to move back and forth to a suitable position. Then, place the shaft 3 between the two shock absorption wheels 93. Rotate the reverse-threaded rod 91 until the bottoms of the two shafts 3 are limited. Then, start the hydraulic telescopic rods 82 to drive the support plate 83 to move up and down until the shaft 3 and the center point 22 are on the same axis. Then, start the first driving motor 43 to drive the rotation of the threaded rod in the first slide rail 41. The first moving seat 42 moves towards the left end of the shaft 3 until the center point 22 on the surface of the first moving seat 42 reaches the top of the right end of the shaft 3. The two center points 22 clamp and fix the shaft 3. Then, the center point 22 drives the shaft 3 to rotate, and the cutter head 10 rotates to polish the surface of the shaft 3. Due to the support of the shock absorption wheels 93 at the bottom of the shaft 3 and the cooperation with the shock absorption blocks 92, the vibration of the shaft 3 during the processing is reduced.

During the processing, the front and rear moving component 6 can drive the auxiliary support components 8 to move through the connecting transmission components 7.
