Description

Technical Field

[0001] The invention relates to the technical field of automobile component assembly, and in particular to a tool and equipment for installing bolts in a housing. Background Art

[0002] The cover is a relatively independent assembly in the automobile body structure and an important part of the automobile. Among them, there are many types of hinges used to install the automobile cover, and the most commonly used cover hinges are single-axis hinge type hinges and multi-link hinges. Usually, the connecting hinge is first positioned on the vehicle body, and then the bolts are passed through the bolt holes on the cover and tightened on the vehicle body to fix the connecting hinge to the vehicle body. However, due to the complex structure of the cover, the operating space is narrow when installing the connecting hinge, and manual assembly and manual tightening are not used. Therefore, it is necessary to design a cover hinge tightening device to solve the problem that the connecting hinge is not easy to assemble and tighten in a narrow operating space.

[0003] In the prior art, the traditional connecting hinge assembly positioning tool generally adopts the method of opening the cover shell 25° for positioning and then tightening the bolts. The advantage is that an ordinary wrench is used for tightening, and the screws are fully exposed to the operator's field of vision; or a special tool wrench with a duckbill head is used to tighten the bolts. The advantage is that the positioning accuracy of the cover shell can be better guaranteed.

[0004] However, it is difficult to visually monitor the gap difference when opening the cover for positioning with the traditional connecting hinge assembly positioning tool, and the accuracy of the hinge shaft will cause the open and closed states to be different, resulting in unstable gap difference. The use of customized duckbill wrenches is costly and difficult to popularize. Summary of the invention
