Fastening system capable of compensating tolerance

Abstract

The invention provides a fastening structure capable of compensating tolerance. The fastening structure is simple, convenient to operate and capable of realizing quantitative adjustment among accessories and reducing assembly size errors. The fastening system is assembled between a mounting metal plate and a fastened workpiece, a mounting bolt is sequentially screwed into the fastened workpiece, the fastening system and the mounting metal plate and then is locked through a projection welding nut, the fastening system comprises a limiting piece, a mounting connecting piece and an adjusting piece, the limiting piece is assembled on the fastened workpiece in a limiting mode, the mounting connecting piece is assembled on the limiting piece, the adjusting piece is in threaded connection in the mounting connecting piece, and a first holding mechanism is arranged in the limiting piece, so that the limiting piece, the first holding mechanism and the mounting bolt can be held tightly; a second holding mechanism is arranged in the adjusting piece, so that the adjusting piece, the second holding mechanism and the mounting bolt can be held tightly; a first stop block is arranged on the outer wall of the mounting connecting piece; a limiting structure is arranged on the fastened workpiece, and the limiting structure is provided with the movement allowance of the first stop block on the plane where the fastened workpiece is located.

Description

technical field [0001] The invention relates to the technical field of assembly of auto parts, in particular to a fastening structure for compensating tolerances. Background technique [0002] With the rapid development of the automobile industry, the assembly requirements for automobile hidden door handles, headlights and other parts that need to adjust the clearance and surface difference during the assembly process are also getting higher and higher. In order to ensure the appearance of the sheet metal, such as the current The installation sheet metal of the hidden door handle of the car is fixed with the outer sheet metal by glue. However, during the assembly process, the gap and surface difference between the accessories need to be adjusted. This assembly method is not easy to control and will make the accessories The assembly size error between them is relatively large. Contents of the invention [0003] In view of the above problems, the present invention provides ...
