Description

Technical Field

[0002] At present, the industry generally adopts two methods to assemble the tailgate: directly assembling it on the body without the help of tooling and assembling it with the help of tooling. Without the help of tooling, two people are required to cooperate in the operation and the working hours are long. With the help of tooling, the tailgate is generally fixed in the approximate position with a limit block, and then fine-tuned. The tooling structure is generally six limit blocks embedded with magnets. The thickness of each two limit blocks is made according to the theoretical gap between the tailgate and the top cover, side wall, and rear wall. Each two are first fixed at the specified position of the top cover, side wall, and rear wall. Then, an operator on the outside of the car body assembles the tailgate against the limit block to the car body, and another operator on the inside of the car body uses tools and standard parts to fasten the tailgate to the car body. After the assembly is completed, the tooling is removed, and the tailgate is fine-tuned to meet the requirements of the gap and flatness between the tailgate and the side wall and top cover. However, this type of tooling has the disadvantages of a large number of parts, unstable assembly consistency, and labor-intensive and time-consuming fine adjustments. Summary of the invention
