Abstract: With the improvement of line flexibility, major automotive original equipment manufacturers are now enhancing the flexible design of line clamping. Based on current body-in-white welding fixtures and their associated control programs, this study utilizes CATIA software to design and verify flexible body-in-white fixtures. By upgrading existing fixtures, it focuses on addressing insufficient accessibility of positioning and clamping mechanisms. The research primarily explores integrated design of telescopic pins and clamping units, as well as linear guide positioning in small-space dihedral configurations. These innovations aim to achieve flexible structures in automotive welding fixtures and production lines, thereby improving welding fixture efficiency and precision, and advancing automation and standardization in automotive manufacturing.
