[0032] A second clamping block 9 is fixed at one end of the lifting plate 10 and located on the top of the first clamping block 8. The second clamping block 9 is symmetrically arranged with the first clamping block 8, so that the second clamping block 9 can be lowered and approached to the first clamping block 8 to clamp and fix the welded object; an adjustment drive motor 11 is fixed inside one end of the rotating column 3, and a lifting threaded rod 12 is connected to the output end of the adjustment drive motor 11. The outer side of the lifting threaded rod 12 is threadedly connected to the lifting plate 10, so that the rotation of the lifting threaded rod 12 drives the threaded lifting plate 10 to rise and fall;

[0033] A synchronous ring 5 is fixed on the outside of the rotating column 3 and located inside the support frame 2. The synchronous ring 5 is slidably connected to the support frame 2, so that the rotation of the rotating column 3 inside the support frame 2 is more stable. At the same time, the rotating column 3 and the synchronous ring 5 rotate synchronously. Positioning components for limiting the rotation of the synchronous ring 5 are installed on both sides of the support frame 2. The positioning components include a positioning column 6 and a tension spring 7. A positioning column 6 is slidably connected to the inside of one side of the support frame 2. One side of the positioning column 6 is slidably connected to the synchronous ring 5, so that when the tail end of the positioning column 6 is located inside the synchronous ring 5, the rotation of the synchronous ring 5 and the rotating column 3 on the inner side of the support frame 2 is limited. A tension spring 7 is sleeved on the outside of the positioning column 6. One side of the tension spring 7 is fixed to the support frame 2, and the other side of the tension spring 7 is fixed to the positioning column 6, so that pulling out the positioning column 6 drives the tension spring 7 to stretch.

[0035] The top of the first clamping block 8 and the bottom of the second clamping block 9 are both provided with clamping surfaces, which are composed of an arc-shaped clamping surface 13 and a parallel clamping surface 14. Both sides of the arc-shaped clamping surface 13 are connected to the parallel clamping surfaces 14, so that the arc-shaped object can be clamped by the two arc-shaped clamping surfaces 13 on the first clamping block 8 and the second clamping block 9. At the same time, the special-shaped object is also clamped and fixed at this position. When a plate-like object is clamped, it can be clamped by approaching the parallel clamping surfaces 14.

[0036] The use process of a welding device for steel structure provided by the utility model is as follows: when in use, the object to be welded is placed between a first clamping block 8 and a second clamping block 9 on the same clamping mechanism, and then the adjustment drive motor 11 inside the rotating column 3 in the same clamping mechanism is energized to drive the corresponding lifting threaded rod 12 to rotate, so that the rotation of the lifting threaded rod 12 drives the threaded lifting plate 10 to descend, and the descent of the lifting plate 10 drives the second clamping block 9 to descend, so that the second clamping block 9 is close to the first clamping block 8 to clamp the welding object, and when the welding object needs to be rotated, by pulling the positioning column 6, the positioning column 6 drives the tension spring 7 to stretch and disengages from the slidingly connected synchronous ring 5, and then the rotating column 3 and the clamped welding object can be driven to rotate by holding the rotating pull ring 4, and after rotation, the positioning column 6 enters the interior of the synchronous ring 5 for rotational positioning, thereby reducing the inaccurate positioning caused by re-clamping after disassembly.
