Technical Problem
[0004]针对窗下沿梁焊接变形的调形环节,普遍使用大锤对侧围骨架的变形部位进行敲击,以校正其直线度偏差,不同的操作力度、敲击角度及判断标准存在差异,易导致调形后的侧围骨架直线度一致性较差,难以稳定保障侧围骨架的结构精度,进而影响后续白车身侧围蒙皮的装配质量
Benefits of technology
本发明的反变形装置中,支撑平台作为整个装置的基础承载部件,其滑道为滑动组件提供了稳定的移动路径,滑动组件顶面与支撑平台顶面齐平,确保后续压紧组件施力基准。反变形垫板布置在接触点处可对侧围骨架局部形成支撑,滑动组件对应最大间隙点设置,再配合压紧组件将侧围骨架贴合在滑动组件上。支撑平台作为基础承载结构,滑动组件提供可调节的支撑点,反变形垫板调整局部高度,压紧组件实现刚性固定。通过各部件配合针对性地在焊接前为侧围骨架施加反向预变形,抵消侧围骨架在焊接过程中因受热不均产生的变形,解决了现有技术中调形效率低、精度差的问题,保障侧围骨架焊接完成后的直线度符合误差要求,提高了侧围骨架的生产效率和产品质量。

Abstract
The present application relates to the technical field of passenger car manufacturing, and particularly relates to a passenger car side wall framework window lower edge beam welding reverse deformation device and method. The reverse deformation device comprises a support platform, a sliding assembly, a reverse deformation pad plate and a pressing assembly; the support platform is provided with a slide, and the sliding assembly is slidingly installed in the slide of the support platform; the side wall framework is in a plurality of arc shapes after front welding, and each arc shape has a contact point and a maximum gap point with the support platform in an initial state of the side wall framework placed on the support platform; the reverse deformation pad plate is arranged between the side wall framework and the support platform and located at the contact point position; the sliding assembly is located at the maximum gap point position; and the pressing assembly is used for attaching the side wall framework to the sliding assembly. The present application actively controls the deformation amount in the reverse welding stage, reserves a deformation amount for welding of the side wall framework window lower edge beam welding deformation position, improves the framework straightness, and improves the production efficiency and product quality.
