摘　　要：车架总成运用在皮卡、轻卡和非承载式乘用车上,是非常重要的底部骨架件。车架总成质量对整车安全、舒适性影响较大。车架总成中纵梁总成的焊接变形最难控制,传统的控制焊接变形方式已经很难保证纵梁总成变形量,使得车架整体尺寸控制和装配都难达到高品质要求,为了提升车架总成尺寸,降低车架纵梁总成焊接变形量,本文对车架纵梁总成焊后变形进行研究,从夹具设计和机器人焊接布局两方面来保证纵梁总成焊后变形控制在2.3-3.2mm,从而保证车架总成尺寸和生产效率。The frame assembly is a very important bottom frame component used in pickup trucks,light trucks,and non load carrying passenger cars.The quality of the frame assembly has a significant impact on the safety and comfort of the entire vehicle.The welding deformation of the longitudinal beam assembly in the frame assembly is the most difficult to control.Traditional methods of controlling welding deformation are already difficult to ensure the deformation of the longitudinal beam assembly,making it difficult for the overall size control and assembly of the frame to meet high-quality requirements.In order to improve the size of the frame assembly and reduce the welding deformation of the frame longitudinal beam assembly,this article studies the deformation of the frame longitudinal beam assembly after welding,From the perspectives of fixture design and robot welding layout,ensure that the deformation of the longitudinal beam assembly after welding is controlled within 2.3-3.2mm,thereby ensuring the size and production efficiency of the frame assembly.
