Abstract: In this paper, combining the quality of parts, body mounting holes and assembly process, a comprehensive analysis of the clearance between the lower guard plate in the middle section of the instrument panel and the instrument panel body is carried out, and finally it is determined that the sinking of the white body floor sheet metal is the main cause of the clearance tolerance problem. And then formulated corresponding improvement measures to eliminate the impact of sheet metal sinking, improve the appearance of the instrument panel, and accumulate experience for subsequent model design.
