While the second screw rod rotates, it drives the movable plate to move along the slide rail, and pushes the moving rod to move, and the moving rod pushes the second grinding part into the interior of the pipeline; because the movable plate is connected to the first slide seat through the connecting rod, the first slide seat can move synchronously along the slide rail while the movable plate moves, so that the first grinding part and the second grinding part always keep moving in relative position, and then drive the cylinder to push the first grinding part to fit the outer wall of the pipeline. At this time, the inner and outer walls of one end of the pipeline respectively contact the first grinding part and the second grinding part, so as to facilitate the subsequent processing of the inner and outer walls of the pipeline at the same time, thereby improving the processing efficiency.

The outer wall cleaning component includes a slide rail 13, a first slide seat 14, a cylinder 15, a first grinding part 16, a servo motor 20, a second screw rod 21 and a connecting rod 22. The slide rail 13 is installed on the base 1 through a support seat 101. The first slide seat 14 and the movable plate 25 both slide on the slide rail 13 and are connected through the connecting rod 22. The second screw rod 21 is fixedly installed at the output end of the servo motor 20 and is transmission-connected with the movable plate 25. The cylinder 15 is installed on the first slide seat 14, and the first grinding part 16 is installed at the output end of the cylinder 15.

[0030] A plurality of support mechanisms are also installed on the base 1, and the support mechanisms include a support portion 10, a support frame 11 and a support stud 12. The support frame 11 can be moved up and down and installed on the support stud 12, and the bottom of the support frame 11 is supported by the upper nut of the support stud 12. The support portion 10 is installed on the support frame 11. The support portion 10 is composed of two opposing truncated cone structures as a whole. A cylindrical roller is also installed on the support portion 10 to reduce friction with the pipeline. It should be noted that the support portion 10 is composed of two opposing truncated cone structures as a whole, so as to limit and support the pipeline. A plurality of cylindrical rollers are installed on the support portion 10 to reduce the friction between the pipeline and the support portion 10.

[0034] Then, the hydraulic cylinder 19 can be driven to push the movable group of support seats 101 to approach the other end of the pipeline, and the servo motor 20 can be driven to drive the second screw rod 21 to rotate. While the second screw rod 21 rotates, it drives the movable plate 25 to move along the slide rail 13, and pushes the moving rod 18 to move, and the moving rod 18 pushes the second grinding part 17 into the interior of the pipeline; because the movable plate 25 is connected to the first slide seat 14 through the connecting rod 22, the first slide seat 14 can be synchronously moved along the slide rail 13 while the movable plate 25 moves, so that the first grinding part 16 and the second grinding part 17 always keep moving in relative position, and then drive the cylinder 15 to push the first grinding part 16 to fit the outer wall of the pipeline, at this time, the inner and outer walls of one end of the pipeline are respectively in contact with the first grinding part 16 and the second grinding part 17;

[0035] At this time, the reduction motor 2 can be driven to drive the rotating part 4 to rotate through the gear 3, and then the pipe clamped by the limit clamp 9 will synchronously rotate with the rotating part 4. While the rotating part 4 rotates, the servo motor 20 is driven again to drive the moving plate 25 to move through the second screw 21, and then the first grinding part 16 and the second grinding part 17 are synchronously moved, so that the inner and outer walls of the rotating pipe are processed.

[0036] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
