On the outside of both movable frames 2, there are installed lifting seats 3 that can reciprocate up and down. On the inner sides of the outside of both lifting seats 3, there are installed arc-shaped clamping seats 4 that can reciprocate left and right. Inside both arc-shaped clamping seats 4, there are rotatably installed clamping conveyor belts 5. In the middle positions of the other two sides outside the processing table 1, there are rotatably installed telescopic mechanisms, which are located between the two processing tables 1 and are rotationally matched with each other.

The two movable frames 2 are respectively in threaded cooperation with the two lead screws. On the other two sides outside the processing table 1, there are installed pin posts 7, and locking nuts 13 are threadedly installed on their exteriors. The two telescopic mechanisms are respectively in rotational cooperation with the two pin posts 7. The size of the movable frame 2 is adapted to the size inside both sides of the processing table 1, which can limit the movable frame 2 so that it can only perform reciprocating motion. By tightening the locking nut 13, the telescopic mechanism can be locked and positioned.

[0028] As an alternative technical solution of the present invention, inside the vertical sections of both movable frames 2, there are installed lead screws that are driven to rotate by a second motor 8.

And through the rotation of the clamping conveyor belt 5, the exhaust pipe can be driven to rotate, which is convenient for comprehensively processing the outer surface of the exhaust pipe. Moreover, the clamping conveyor belt 5 can wrap and protect the exhaust pipe, and can prevent the exhaust pipe from being dented and deformed. At the same time, the above mechanisms can realize the up-and-down and front-and-back movement of the exhaust pipe. Telescopic cylinders 10 are rotatably installed on the other two sides of the outside of the processing table 1. A connecting seat 12 that can be telescoped inside and outside is slidably installed on one side of the outside of the telescopic cylinders 10. The two form a telescopic mechanism. The telescopic mechanism can be used to assemble the two processing tables 1 together, and by adjusting the angle between the two processing tables 1, the special-shaped exhaust pipe can be clamped and fixed, which is convenient for processing. A collection tray 6 is slidably installed on the top surface of the processing table 1, which can collect the debris generated by welding or drilling, facilitating the staff to centrally process the debris later.
