[0002] In steel structure buildings, the welding of steel columns is a crucial step. To ensure the accuracy and stability of welding, special jigs are usually used for fixation. Such jigs are generally made of high-strength materials and can withstand a large amount of pressure and heat. The design of the jigs usually takes into account the shape and size of the steel columns, as well as the forces that may occur during the welding process. By using such jigs, workers can weld more accurately, thereby improving the quality and safety of the building.

[0003] However, the existing steel column welding jigs cannot perform automatic welding loading and unloading, and manual loading and unloading is required, which is prone to frequent safety accidents during the welding process. Moreover, the existing jigs cannot be adaptively adjusted automatically according to welding requirements, resulting in the need for manual intervention operations and low welding efficiency.

[0004] Therefore, it is very necessary to propose a jig for steel column welding with a correction structure in this application to optimize the technical problems existing in the existing jigs.

The above patent realizes that the side pressing mechanism can press the first workpiece tightly in different directions, and the clamping mechanism can clamp the second workpiece so that all surfaces of the two workpieces are completely pressed tightly and are not easily loosened, but the above patent cannot realize the function of adjusting the welding points of the steel column.

[0009] In summary, the above-mentioned patent cannot achieve the functions of automatically clamping and loading / unloading steel columns, straightening steel columns, adjusting the clamping and welding angles, detecting the bending of steel columns, and adjusting the welding positions of steel columns, resulting in problems such as low efficiency of manual loading / unloading, poor welding quality, slow welding speed, inability to adaptively adjust according to the welding positions, and low safety; Therefore, the present application proposes a fixture for steel column welding with a detection structure that can achieve the functions of automatically clamping and loading / unloading steel columns, straightening steel columns, adjusting the clamping and welding angles, detecting the bending of steel columns, and adjusting the welding positions of steel columns.
