The flexible track automatic drilling equipment is widely used in aircraft assembly because of the low cost, flexibility and little space occupation. Beginning with the foreign application status, the current domestic demand is analyzed, and BAA300 flexible track automatic drilling equipment is introduced. The drilling experiment is carried out to obtain the position deviation of drilling, and finally the conclusion is obtained that the equipment can be applied on ARJ21 and C919 after improvement.%柔性导轨自动制孔设备因其低成本、柔性、占用空间小的优点,在飞机装配中逐渐被大量应用.本文从国外应用情况开始,分析了现阶段国内的需求,介绍了BAA300柔性导轨自动制孔设备,并开展了制孔工艺试验,获得了制孔的位置偏差和孔质量情况,最终得出了经过设备改进即可应用于ARJ21和C919机身段对接区的自动制孔的结论.
