Abstract: With the continuous introduction of new energy vehicles by vehicle manufacturers, the structural differences in the bottom of the body-in-white between new energy vehicles and traditional fuel vehicles, as well as the increased weight of the new energy body-in-white, pose significant challenges to the load capacity and co-line compatibility of the body-in-white transfer systems and their accompanying fixtures in the welding workshop. This article introduces a multi-platform lightweight and flexible accompanying fixture transmission system suitable for the co-line production of new energy and traditional fuel vehicle body-in-white architectures. This system innovatively incorporates new materials, new processes, and new equipment technologies, achieving a weight reduction of 250 kg for the accompanying fixtures and ensuring that the total load does not exceed the rated load of 1 500 kg for high-speed roller beds after the introduction of new energy vehicles. It realizes the lightweight, flexible, and standardized accompanying fixtures. This further achieves the lean integration of the manufacturing lines for new energy and traditional vehicle body-in-white, providing a reference for the common manufacturing challenges faced by the body-in-white welding workshops of various vehicle manufacturers due to the introduction of new energy vehicle models.
