Problems solved by technology

The lengthening of the dimensional link also makes the accumulation of manufacturing tolerances larger, resulting in poor assembly stability, and cannot well realize the dimensional relationship between the hood hinges, fenders, front doors, and rear doors, and it is easy to repeatedly adjust and disassemble during assembly.

Abstract

The invention relates to an automobile engine cover hinge assembly tool and an assembling method thereof. The automobile engine cover hinge assembly tool comprises a support body, wherein the supportbody is a double-layer frame and comprises an upper support and a lower support, first positioning units and supporting units are arranged in pair on the upper support, second positioning units whichcan move in the length direction of an automobile body is arranged in pair on the lower support, the second positioning units are fixedly connected with third positioning units, the first positioningunits are used for positioning the assembly tool on an automobile body framework, the supporting units are used for supporting the assembly tool on the automobile body framework, the second positioning units are used for aligning the assembly tool to a side-wall main positioning hole of the automobile body framework, and the third positioning units are used for positioning an engine cover hinge onthe automobile body framework. Compared with the prior art, the automobile engine cover hinge assembly tool and the assembling method thereof have the advantages that the problem of the transmissibility of a dimensional chain for assembly of the engine cover hinge is solved, the engine cover hinge changes along with the change of automobile body states during assembly, the requirements for matching with other pieces are met, and repeated disassembly, assembly and adjustment are avoided.

Description

technical field [0001] The invention relates to the technical field of automobile assembly, in particular to an automobile engine cover hinge fitting and an assembly method thereof. Background technique [0002] The bonnet hinge of the car determines the position of the hood on the body. The conventional hood hinge assembly completely uses the installation point at the cabin of the vehicle body to locate the hinge position of the assembly and the engine compartment, which cannot be linked with the assembly dimensions of the front and rear doors of the vehicle body. to associate. Because the assembly sequence of the body is from the rear to the front, if the dimensional chain association is not performed, the assembled hood hinge and the front door will be independent, and the relative size between them in the X direction of the body will deviate due to the fluctuation of the size of the parts. It will cause problems such as the gap difference between the engine cover and th...
