The invention particularly relates to an automobile body-in-white widening method and widening assembly. Comprising the following steps that S1, an engine cover plate widening block, a top cover widening block, a front wall baffle widening block and a back door widening block are manufactured according to widening sizes; s2, widening and remanufacturing the engine cover plate, and welding an engine cover plate widening block with the left part and the right part of the engine cover; s3, widening and remanufacturing the top cover, and welding a top cover widening block with the left part and the right part of the top cover; s4, widening and remanufacturing the front wall baffle, and welding a front wall baffle widening block with the left part and the right part of the front wall baffle; s5, back door widening and remanufacturing are conducted, and back door widening blocks are welded to the left part and the right part of the back door; and S6, the widened parts are placed on a main splicing clamp to be positioned, and main splicing welding is carried out to form a new widened vehicle model. The cost is saved, the precision of the vehicle body is ensured, a mold does not need to be developed again, and the research and development period is greatly shortened.

    本发明具体涉及一种汽车白车身加宽方法及加宽总成。包括如下步骤:S1、根据加宽尺寸分别制作发动机罩板加宽块、顶盖加宽块、前围挡板加宽块和后背门加宽块;S2、进行发动机罩板加宽改制,将发动机罩板加宽块与上述左右两部分发动机罩焊接;S3、进行顶盖加宽改制,将顶盖加宽块与上述左右两部分顶盖焊接;S4、进行前围挡板加宽改制,将前围挡板加宽块与上述左右两部分前围挡板焊接;S5、进行后背门加宽改制,将后背门加宽块与上述左右两部分后背门焊接;S6、将加宽后的零部件放置到主拼夹具定位,进行主拼焊接形成新的加宽车型。本发明节约成本,保证车身精度,不需重新开发模具,大大缩短研发周期。
