The lifting cylinder 20 installed at the bottom of the rotating chassis 10 can realize the lifting and lowering adjustment of the rotating chassis 10 and its internal structure. The built-in servo reduction motor 14 of the rotating chassis 10, as a driving source, provides a stable and controllable rotational power for the uniform rotation shaft 11. Through the design of the replaceable sleeve 50, the structure can be applied to workpieces of various shapes and sizes. By replacing the replaceable sleeves of different specifications, the circumferential welding of different workpieces can be easily achieved, thereby improving the versatility and utilization efficiency of the equipment.

[0031] Furthermore, the top of the lifting rod 21 of the lifting cylinder 20 is connected to the bottom of the rotating chassis 10, and the horizontal rod 31 of the horizontal adjustment cylinder 30 is connected to the side wall of the lifting cylinder 20. By setting the top of the lifting rod 21 of the lifting cylinder 20 to be directly connected to the bottom of the rotating chassis 10, it is ensured that the lifting cylinder 20 can directly and effectively drive the rotating chassis 10 to perform lifting and lowering movements. The horizontal rod 31 of the horizontal adjustment cylinder 30 is connected to the side wall of the lifting cylinder 20, so that the horizontal adjustment cylinder 30 can fine-tune the horizontal position of the lifting cylinder 20.
