[0002] With the development of the times and the progress of industrial technology, the speed of automobile production lines has been improved, and automobile production has also increased. Currently, the production efficiency of newly built factories is generally 60 JPH, which means that a car can be produced in an average of 54 seconds. However, people's aesthetic appreciation of car bodies has increased, requiring a balance between gaps and surface differences in the appearance of automobiles.

[0003] In existing technologies, the four-door hinges have poor precision when installed manually. Their installation dimensions are prone to large fluctuations, and the overall installation speed is slow. Furthermore, the door angle is difficult to control and adjust, making it impossible to achieve fast and accurate installation. This results in poor quality control of the installed products and affects the overall efficiency of automobile production.

[0004] Therefore, a four-door hinge mounting fixture for automobiles is needed to solve the above problems. Utility Model Content
