The invention discloses a flexible vehicle body assembly system which comprises a bottom positioning mechanism, a positioning frame, a positioning gripper, an external walking shaft and a manipulator. The positioning frame is used for accurately positioning and clamping a top cover front cross beam and a rear wall upper cross beam; the positioning tongs are used for accurately positioning and clamping the left/right side wall and positioning and clamping the rear wall upper cross beam and the top cover front cross beam; the external walking shafts are arranged on the two sides of the bottom positioning mechanism and used for driving the mechanical arm to move. And the manipulator is used for grabbing the welding gun to weld the vehicle body. Compared with the prior art, the invention has the following beneficial effects: for the general assembly of a specific vehicle model, only a specific positioning gripper needs to be designed, the bottom positioning mechanism, the positioning frame, the external walking shaft and the manipulator can be universally used, and the invention has the advantages of high equipment utilization rate, strong vehicle model expandability, small investment scale and the like, and is suitable for the flexible production of various small-batch vehicle models.

    本发明公开了一种柔性车身总拼系统,包括底部定位机构、定位框架、定位抓手、外部行走轴及机械手;所述定位框架用于为顶盖前横梁和后围上横梁提供精确定位和夹紧;所述定位抓手用于对所述左/右侧围进行精确的定位夹紧以及对所述后围上横梁及所述顶盖前横梁进行定位夹紧;所述外部行走轴布置于所述底部定位机构的两侧,并用于驱动所述机械手移动;所述机械手用于抓取焊枪进行车身焊接。本发明的有益效果是:对于特定的车型的总拼来说,只需要设计特定的定位抓手即可,底部定位机构、定位框架、外部行走轴及机械手可以通用,具有设备利用率高,车型可扩展性强,投资规模小等优势,适合于多品种小批量车型的柔性化生产。
