The invention relates to a box body electroplating rotating tool. The box body electroplating rotating tool comprises a main body frame, wherein a supporting arm is arranged on the main body frame, abox body fixing seat is rotatably arranged on the bottom of the supporting arm in an assembled mode, and a fixing structure for being matched with a fixing hole on a box body to fix the box body is arranged on the box body fixing seat. A rotating axis of the box body fixing seat is horizontally arranged, and a driving mechanism for driving the box body fixing seat to rotate is further arranged onthe main body frame. According to the box body electroplating rotating tool, the box body fixing seat is rotatably arranged on the main body frame in an assembled mode, and the rotating axis is horizontal; an opening of an inner cavity of a post-mounting workpiece can be rotated in a vertical plane, the opening of the inner cavity of the workpiece in the electroplating process is ensured to be upward, the opening of the inner cavity of the workpiece is downward after being rotated in the light-emitting process, so that liquid can be discharged in time; and the problems that coating dissolvingand bottom leakage on the bottom of the inner cavity of the workpiece caused by liquid discharging is not timely in the light-emitting process when the workpiece with the inner cavity is galvanized inthe prior art are solved.
