Description

Technical Field

[0001] The utility model relates to the technical field of automobile assembly, and more specifically, to an integrated hood hinge fixture. Background Art

[0002] The hood hinge of a car determines the position of the hood on the body. Conventional hood hinge fixtures completely use the mounting points on the body cabin to locate the fixture and the hood hinge position, and cannot be associated with the assembly dimension chain of the front and rear doors of the body. Since the assembly sequence of the body is from back to front, if the dimension chain is not associated, the assembled hood hinge will be independent of the front door. The relative size between the two in the X direction of the body will deviate due to the fluctuation of the part size state, which will cause the gap difference between the hood and the fender or the gap difference between the fender and the front door, and the repeated adjustment of the hood hinge, which will affect the manufacturing efficiency and appearance quality.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
