The invention discloses a top cover cross beam clamp, a body-in-white main splicing clamp assembly and a welding positioning method.The top cover cross beam clamp comprises a bottom frame, a positioning clamping mechanism set, a bottom frame positioning mechanism and a hoisting mechanism, the bottom frame comprises an overall frame, and the overall frame comprises cross beams and longitudinal beams; each positioning and clamping mechanism set comprises a first positioning and connecting assembly and a second positioning and connecting assembly, the first positioning and connecting assemblies and the second positioning and connecting assemblies are oppositely fixed to the longitudinal beams, the bottom frame positioning mechanisms are arranged at the corners of the bottom frame, and the lifting mechanisms are evenly arranged on the bottom frame. The clamp is simple in structure, one-time positioning connection of a plurality of top cover cross beams can be easily completed, the clamp and the top cover cross beams are lifted together through the lifting mechanism, the chassis positioning mechanism and the body-in-white main splicing clamp are accurately positioned, welding is conducted after the top cover cross beams and the upper portion of the body-in-white side wall are accurately positioned, welding is easy, and welding efficiency is high. Spot welding space is sufficient, precision is high, after welding, the clamp is loosened to lift and move out, and operation is easy.

    本发明公开了一种顶盖横梁夹具、白车身主拼夹具总成及焊接定位方法,顶盖横梁夹具包括底架、定位夹紧机构组、底架定位机构和起吊机构,底架包括整体框架,整体框架包括横梁和纵梁,每个定位夹紧机构组包括第一定位连接组件和第二定位连接组件,第一定位连接组件和第二定位连接组件相对固定在纵梁上,底架定位机构设置于底架的边角上,起吊机构均匀设置于底架上。本发明的夹具的结构简单,能够轻松完成多个顶盖横梁一次定位连接,通过起吊机构将本夹具与多个顶盖横梁一起吊起,底架定位机构与白车身主拼夹具精准定位,实现顶盖横梁与白车身侧围上部精准定位后进行焊接,焊接容易,点焊空间充足、精度高,焊接后松开夹具将其吊起移出,操作简单。
