摘　　要：针对某型飞机起落架后支架筋板孔19H8加工空间狭小的问题,通过方案的迭代分析,结合夹具设计、过程控制和刀具优化,从工艺设计、程序输出、仿真验证、现场制造等环节进行了深入的研究,不但保证了筋板孔19H8空间位置尺寸精度要求,还为类似后支架工件的异地协同,互换装配,提供了一种工艺设计方案。In order to solve the problem of the narrow processing space of the rib plate hole19H8 of the landing gear of a certain type of aircraft landing gear,this paper carries out iterative analysis of the scheme,fixture design,process control and tool optimization.Process design,program output,simulation verification,on-site manufacturing and other links are studied,which not only guarantees the dimensional accuracy requirements of the rib hole19H8 space,but also provides a process design scheme for the off-site collaboration and interchange assembly of similar rear support workpieces.
