[0023] When using this solution, the column is placed inside the jacket 40, and the second hydraulic cylinder 41 is started to drive the clamping plate 42 to move, so as to clamp and fix the column inside the jacket 40, thereby limiting the position of the column. Then the thin plate is placed on the top of the welding table 18, and the plate is supported by the welding table 18, which facilitates welding of the plate and the column and improves stability during welding.

[0026] The second motor 37 is started to drive the third threaded rod 12 to rotate, so that when the third threaded rod 12 rotates, the threaded plate 14 is driven to rise or fall, so that the threaded plate 14 drives the movable sleeve 13 to move up and down, and the height of the movable sleeve 13 is adjusted. When the movable sleeve 13 moves, the support plate 15 is driven to move, so that the support plate 15 drives the support sleeve 16 and the connecting plate 17 to move up and down, and the connecting plate 17 drives the welding table 18 and the extension plate 19 to move up and down, so that the welding table 18 and the extension plate 19 can be pressed against the thin plate. Lifting is carried out to adjust the installation height of the thin plate, and the push plate 20 is driven to move by the first hydraulic cylinder 21 to drive the extension plate 19 to slide inside the welding table 18, thereby increasing the support range of the welding table 18 and the extension plate 19 for the thin plate. After the thin plate is lifted to the welding position, the cylinder 49 is started to send the welding machine 9 to the welding point, and the thin plate is welded to the column by the welding machine 9, which improves the stability of the thin plate welding, prevents the long thin plate from bending and deforming in the middle during welding, and improves the welding quality.

[0027] When the third threaded rod 12 rotates, the vertical slots 24 on both sides of it limit the limit bar 23, so that the limit bar 23 drives the rotating ring 22 to rotate. When the rotating ring 22 rotates, it drives the first bevel gear 25 to rotate, and the first bevel gear 25 drives the second bevel gear 27 to rotate. When the second bevel gear 27 rotates, it drives the rotating sleeve 26 and the two-way threaded rod 28 to rotate, so that the two-way threaded rod 28 drives the two moving blocks 29 to move in opposite directions on its outside when rotating, so that the two moving blocks 29 drive the guide shaft 30 to push and pull the two sides of the telescopic frame 31, so that the top end of the telescopic frame 31 lifts and drives the upper slider 33 to slide inside the upper slide rail 32, and at the same time, the bottom end of the telescopic frame 31 drives the lower slider 35 to slide inside the lower rail 34. The telescopic frame 31 is movable, so that the extended height of the telescopic frame 31 is always consistent with the lifting height of the extension plate 19, and the extension plate 19 is always supported, thereby improving the supporting stability of the extension plate 19, improving the strength, and ensuring that the supporting force of the plate is always stable. The anti-deformation welding equipment realizes the precise positioning and adaptive clamping of the shelf columns and thin plates through the multi-directional adjustment mechanism and the synchronous lifting structure, and utilizes the bidirectional threaded transmission of the bidirectional threaded rod 28 and the articulated support structure of the telescopic frame 31 to ensure the dynamic and stable support of the thin plate during the welding process. The height-adjustable welding table 18 and the extension plate 19 effectively suppress the bending deformation during welding of long thin plates. Its modular design can adapt to workpieces of different sizes, which improves the welding quality and efficiency as a whole.
