The output end of the brake servo motor 84 drives the transmission gear 85 to mesh and drive the internal gear ring 83, so that the internal gear ring 83 drives the output sleeve 82 and the double-sided grinding assembly 7 to rotate synchronously. Furthermore, the two grinding plates 72 synchronously grind and trim the surface and inner wall of the side wall of the end of the cylinder joint 2 to be repaired. After completion, turn off the four electric push rods 42, reset the four ball head clamping rods 43, and take out the cylinder joint 2, then it's done.

[0034] Embodiment 2

[0035] Working principle: When in use, set the clamping assembly 4 to two. For the specific trimming operation of the cylinder joint 2, it can be operated according to the steps of the above Embodiment 1. After the trimming of the two cylinder joints 2 is completed, the two cylinder joints 2 can be respectively sleeved inside the two clamping sleeve plates 41. Then, start the four electric push rods 42 corresponding to each of the two clamping sleeve plates 41. The output ends of the four electric push rods 42 drive the corresponding ball head clamping rods 43 to clamp and limit the front and rear ends of the corresponding cylinder joint 2 respectively. After the two cylinder joints 2 are clamped stably, temporarily turn off the first electromagnets 6 corresponding to the bottoms of the two clamping sleeve plates 41. Then, push the two clamping assemblies 4 to align and fit the trimmed ports of the two cylinder joints 2. Then, turn on the first electromagnets 6 provided at the bottoms of the two clamping sleeve plates 41 again to stabilize the two clamping assemblies 4 and the two cylinder joints 2 again. Then use the welding robot 3 to weld and assemble the two cylinder joints 2, then it's done.
