Pxe piston turnover box

The utility model relates to the field of piston production equipment and particularly discloses a PXE piston turnover box which can prevent aluminum scrap from occurring in a box body and can realize the positioning of pistons. The PXE piston turnover box comprises the box body. A plurality of piston placing positions are uniformly arrayed in the box body at intervals. Rectangular bulges are arranged at spacing positions of the piston placing positions on one side of the box body. Junctions of every four piston placing positions and the spacing positions of the piston placing positions on the side corresponding to the side on which the rectangular bulges are arranged are respectively provided with a positioning bulge. Half positioning bulges are arranged at the spacing positions of the piston placing positions on the other two sides. The PXE piston turnover box has the advantages that since the piston placing positions are of hollow structures, the aluminum scrap can be effectively prevented from being retained in the box body, influencing the positioning of the pistons and scratching the surfaces of the pistons; by arranging the positioning bulges, the pistons in the turnover box can be enabled to be in a uniform direction, the machining and the clamping by a manipulator are facilitated, the production efficiency is greatly improved, and the production cost is reduced.
