The utility model provides an overturn tooling, including base and set up the rotation part and first drive part on the base, rotation part includes mounting rack and set up the bearing unit and limit unit on the mounting rack, the bearing unit includes a plurality of bearing subassembly along the interval arrangement of first direction, the limit unit includes the limit unit, every two adjacent bearing assemblies define a containing cavity used for containing a part to be turned over; the limiting unit is used for limiting the to-be-overturned part at a preset position of the containing cavity, the first driving part is in transmission connection with the rotating part, and the first driving part can drive the rotating part to rotate and overturn the limited to-be-overturned part to a preset angle. According to the overturning tool, the containing cavity is defined between the bearing assemblies, the bearing effect on the to-be-overturned part is improved, the stability of the to-be-overturned part in the overturning process is improved through the limiting unit, the rotating part is driven to rotate through the first driving part, the to-be-overturned part is overturned to the preset angle, and the overturning efficiency is improved. And the overturning precision of the overturning tool can be improved.
