[0002] The body in white of a car refers to the body structure of the car after welding but before painting, excluding moving parts such as the four doors and two covers. It is the installation base of the body, decorative parts and accessories. It is generally welded from the front fender, engine hood, side panels, rear panels and floor. The body in white is the foundation of the car body structure. It carries most of the car's structural and functional components, such as the engine, chassis, seats, electrical system, etc. The design and manufacturing quality of the body in white directly determines the safety, comfort and handling performance of the car.

[0003] In the process of automobile manufacturing, the manufacture of the body in white is a key link, and the subsequent installation of moving parts such as four doors and two covers is required. In terms of structure, the door is generally composed of the door outer panel, the door inner panel, the door outer panel reinforcement plate, the door anti-collision beam, the door support beam, the hinge reinforcement plate, the lock reinforcement plate and the door guide rail. Among them, the door outer panel is the appearance part of the door, and its rigidity is generally poor, so it is necessary to improve its rigidity by using high-strength steel plates or bake-hardened steel. The door inner panel is the carrier of the door accessories, generally using Low carbon steel plates are stamped and formed, and their structures can be roughly divided into two types: integral door inner panels and split door inner panels. In the installation of car doors, auxiliary tooling is needed to assist in the transfer of car doors. The tooling in the prior art generally uses multiple tubes to assemble into a frame, and suction cups are installed on the frame to adsorb the car door for transfer. However, this frame structure is fixed and cannot be adjusted, and it is difficult to adapt to the adsorption needs of different parts of the car door. Therefore, the utility model proposes an auxiliary tooling for assembling automobile body-in-white door body to solve the problems existing in the prior art. Utility Model Content
