Fixing structure for intelligent manufacturing of steel structure

The invention belongs to the field of steel structure intelligent manufacturing, and particularly relates to a steel structure manufacturing fixing structure which comprises a base arranged at a robot welding machine station, a sliding plate is slidably arranged on the base, a stand column and an adjusting column are arranged at the top of the sliding plate, and second connecting pieces are rotatably installed at the tops of the stand column and the adjusting column through connecting assemblies. The bottom of the stand column is fixedly connected with a sliding plate, the bottom of the adjusting column is rotatably connected with the sliding plate through a rotating assembly and rotates around the stand column in the circumferential direction, and the second connecting piece and the first connecting piece are perpendicular and located on the same horizontal plane. According to the welding device, the connecting pieces can be welded in batches, the prefabricated connecting pieces of the same structure can be
