The invention belongs to the technical field of automobiles, and particularly relates to a side enclosure outer plate tail springback control structure. The structure comprises a first positioning block, a second positioning block, a third positioning block, a rotating block, a supporting block, a connecting block, an air cylinder and a clamp base. The first positioning block is fixed to the supporting block; the second positioning block is fixed to the supporting block through the connecting block; the third positioning block is fixed to the lower end of the rotating block; the rotating blockis connected with a movable end of the air cylinder; the air cylinder is fixed to the supporting block; the supporting block is fixed to the clamp base through a connecting plate; and the positioningblock attracts a side enclosure outer plate part. With the side enclosure outer plate tail springback control structure, the dimensional accuracy of the side enclosure outer plate part can be effectively controlled in the welding process, and the debugging period can be remarkably shortened.
