Turnover welding frame for manufacturing circular tube supporting assembly

The utility model relates to the field of welding, in particular to an overturning welding frame for manufacturing a round pipe supporting assembly, which comprises a supporting frame, a rotating shell is movably mounted at the top of the right side of the supporting frame through a damping rotating shaft, and a rotating rod is arranged on the right side of the rotating shell in a penetrating manner. A circular pipe body is inserted between the two clamping arms, a rotating rod is rotated to enable a rotating disc to rotate, the rotating disc enables a driving rod to move, the two clamping arms move in opposite directions through a driving assembly to clamp and fix the circular pipe body, and during the period, a limiting assembly can prevent the rotating rod from rotating, and when an angle steel body is welded, a user can conveniently weld the angle steel body. The rotating shell can be rotated, due to the fact that the rotating shell and the supporting frame rotate in a damping mode, the angle steel body i
