Abstract

The invention relates to the field of automobiles, in particular to a double guide positioning device for mounting an auxiliary frame. The double guide positioning device comprises the auxiliary frame, a front girder, a bolt and a nut, wherein a connecting tube is arranged on the auxiliary frame; a connecting end of the connecting tube is horizontally bent; the front girder and the connecting tube are fixedly connected by the bolt and the nut. According to the double guide positioning device, the dimensional precision for assembly can be improved, and deviation of a finished vehicle is avoided; the extending length of the bolt can be shortened, and the difficulty of final assembly for the nut is reduced; the double guide positioning device provides the guidance for the assembly of the auxiliary frame, so the non-value-added adjusting time in the assembly process is shortened; the double guide positioning device provides assembly guidance for the connecting bolt, so screw loosening when the nut and the bolt are matched is reduced.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a double-guide positioning device installed on a sub-frame. Background technique [0002] In the prior art, the structure in which the sub-frame is connected to the front frame is that bolts pass horizontally through connecting pipes to fixedly connect the sub-frame and the front frame, which is inconvenient to connect during installation and reduces work efficiency. [0003] At the same time, during the installation of the sub-frame, it was found that the welding bolts on the car body were long, and the verticality of the bolts was difficult to ensure, resulting in failure of the guide, and it was difficult to ensure assembly, and even the thread and the sub-frame interfered and slipped during the assembly process. . The size of the installation point of the sub-frame is unstable, which affects the performance of the whole vehicle, such as deviation. Contents of the invention [0...
