The positioning structure of the instrument panel beam assembly studied in this paper is an optimized designstructure. The positioning structure is reasonable and effective, and has a wide application prospect. The positioning accuracyis improved by setting the positioning hole and the positioning pin position. Based on the basic mechanical positioningprinciple of two pins on one side, the positioning structure optimizes the relationship between the positioning hole and thepositioning pin, eliminates the assembly errors caused by the size deviation of the positioning hole and the inadequateassembly of the parts, and avoids the assembly errors and difficulties of the rotating and downward orientation system causedby gravity. So as to improve assembly efficiency, improve assembly accuracy and reduce the analysis factors of trial loading.
