以模线样板工作法为主的飞机装配工艺,由于协调环节移形产生的误差、型材和鈑材出厂公差、零件制造误差、装配误差等诸因素的影响,对复杂的协调关系都依靠产品设计、协调方案来保证。 在飞机装配中,因偶然误差和系统误差造成的装配件之间的间隙是常见的。本文探讨对装配间隙进行加垫处理的理论判据和工艺规范;提出采用“加垫补偿”的工艺方法,以期使协调环节化繁为简,起到降低成本和提高产品质量的作用。 Due to the error caused by the coordination of the transfer, the manufacturing tolerance of the profile and the sheet metal, the manufacturing error of the part, the assembly error and other factors, the complicated coordination relationship depends on the product design , Coordinate the program to ensure. In aircraft assembly, gaps between assemblies due to accidental errors and system errors are common. In this paper, the theoretical criterions and technical specifications for padding the assembly gap are discussed. The technology of “padding compensation” is put forward in order to reduce the cost and improve the product quality.
