The invention belongs to the technical field of aeronautical manufacturing, and discloses a repairing method and a line drawing device for a sawtooth skin in butt joint of large components, and the repairing method comprises the following steps: unifying repairing references for different components; performing motion simulation based on skin reconstruction; the sawtooth skin line drawing device is designed according to the parameters of the skin thickness, the repairing position and the included angle between the skin projection and the course, rapid and accurate line drawing is carried out in the final assembly stage according to a tool, and repairing is carried out according to the drawn line. According to the method, the problem that the sawtooth skin is difficult to repair in the final assembly stage due to skin partitioning, curvature change, assembly assembling errors and the like is solved, the limitation that only part manufacturing errors are reduced in an existing method is broken through, and part assembling errors and butt joint errors are reduced; the sawtooth skin repairing scheme can be applied to production practice of butt joint of aircraft parts.

    本发明属于航空制造技术领域,公开了一种大部件对接中锯齿蒙皮的修合方法及画线装置,其包括以下步骤:对不同部件统一修合基准;基于蒙皮重构进行运动仿真;通过蒙皮厚度、修合位置、蒙皮投影与航向夹角参数设计锯齿蒙皮画线装置,依据工装进行总装阶段快速化、准确化画线,并依据画线进行修合。本申请解决因蒙皮分块、曲率变化、组件装配误差等原因导致总装阶段锯齿蒙皮修合较为困难的问题,打破现有方法仅仅降低零件制造误差的局限性,从减少部件装配误差、对接误差入手,使锯齿蒙皮修合方案可以应用于飞机部件对接的生产实际中。
