[0001] The utility model relates to the field of H-shaped steel and box beam column welding manufacturing auxiliary equipment, in particular to a turnover frame which is convenient for adjusting the position of a workpiece. Background Art

[0002] H-shaped steel and box beams are indispensable in high-rise buildings such as factories, and they support the skeleton of the entire structure. They are made by cutting steel plates, assembling spot welding, and welding. In this production process, it is necessary to move between different workstations, or weld welds in different positions, or weld different connecting parts on different surfaces. In order to obtain a better welding position, the workpiece needs to be turned over.

[0003] In traditional production operations, the turning and moving of such workpieces are generally achieved by using an overhead crane. In actual production, due to the limited number of overhead cranes in a workshop, and the possibility of mutual interference between different workstations, it is not safe to use an overhead crane to turn the workpiece.
