The invention provides a hole returning method for a sawtooth-shaped wall plate and an I-shaped frame in a non-open area, and belongs to the field of modern aircraft manufacturing. The edge of one side of the hole forming sample plate is consistent with the theoretical appearance of the sawtooth-shaped wall plate, and the edge of the other side of the hole forming sample plate is consistent with the edge of the other side of the I-shaped frame; hole making hole positions are formed in the hole making sample plate according to theoretical positions, five hole positions with large safety allowance are made into long round holes with the length direction perpendicular to the heading direction, and the long round holes are used for achieving deviation adjustment in the circumferential direction of the I-shaped frame while being fixed in the heading direction so as to eliminate the positioning error between the sawtooth-shaped wall plate and the I-shaped frame; and after the saw-tooth-shaped wall plate and the I-shaped frame are positioned and assembled, the hole making sample plate is attached to the side of the saw-tooth-shaped wall plate, and after the edge contour is aligned with the saw-tooth-shaped wall plate, holes are made in the saw-tooth-shaped wall plate and the saw-tooth-shaped wall plate according to hole making hole positions. On the premise that adjustment compensation in the assembling process is comprehensively considered, the problem that hole forming of the frame part and the wall plate is difficult is solved.
本发明提供一种用于锯齿形壁板与工字形框在不开敞区域的返孔方法,属于现代飞机制造领域。通过制孔样板实现返孔,其一侧边缘与锯齿形壁板理论外形一致,另一侧边缘与工字形框另一侧边缘一致;制孔样板上按理论位置制有制孔孔位,将其中安全余量较大的5个孔位制成长度方向垂直于航向的长圆孔,用于在航向上固定的同时实现沿工字形框周向的偏差调整,以消除锯齿形壁板与工字形框之间的定位误差;将锯齿形壁板与工字形框定位装配好后,将制孔样板贴合在锯齿形壁板侧,边缘轮廓与锯齿形壁板对齐后,按制孔孔位对二者制孔。本发明在综合考虑装配过程时的调整补偿的前提下,解决框零件与壁板制孔难的问题。
