[0002] In pressure vessels, the circular cylinder body is the most common. Firstly, it is more beautiful, and secondly, its strength is relatively high. The cylinder is generally formed by bending a rectangular plate and then welding the two ends to form the cylinder body. Then, arc-shaped bases and lids are added to both ends of the cylinder body for sealing to obtain the pressure vessel. However, during the bending and welding processes of the cylinder body, due to external force factors, the inner and outer surfaces of the cylinder body may be uneven, or the cylinder body may not be round enough. Therefore, it is necessary to correct the roundness of the cylinder body to ensure its roundness.

[0003] As disclosed in the utility model with the authorization publication number CN219335439U, a cylinder roundness correction device for manufacturing pressure vessels. By sleeving the cylinder on the first roller and rotating the first roller, the cylinder rotates, so that the first roller and the second roller squeeze the uneven positions of the cylinder and correct the deformed positions of the cylinder, making the whole cylinder relatively round. When correcting the roundness of the cylinder, by screwing the fixed pipe towards the inner side wall of the ring, the first roller moves towards the inner side wall of the ring, increasing the distance between the first fixing plate and the fixed column. However, during the adjustment process, multiple fixed pipes need to be screwed to adjust to the appropriate distance, which increases the workload of the staff and also results in a slower roundness correction speed of the cylinder, causing low work efficiency.

[0023] When it is necessary to round the cylinder of a pressure vessel, the first motor 13 works to drive the worm 12 fixedly connected to its rotating end to rotate. The rotation of the worm 12 drives the turbine 11 meshing with it to rotate. The rotation of the turbine 11 drives the rotating column 3 fixedly connected to it to rotate. The rotation of the rotating column 3 drives the rotating disk 5 fixedly connected to it to rotate. The rotation of the rotating disk 5 drives the sliding column 8 to move in the sliding groove 7.

[0024] As a further implementation manner of this embodiment, as Figures 1 - 5 shown, a toothed ring 14 fixedly connected to it is sleeved on the outer circumference of the rotating cylinder 2.
