摘　　要：翼梁类零件作为机翼装配的定位基准零件,如何有效减小其在加工中的变形,提高加工精度是一项重要工作。提出一种针对翼梁零件在加工过程中出现的平面度翘曲变形现象的控制方法,根据飞机机翼梁类零件的工艺特点,对生产现场零件的实际变形量进行统计,分析翼梁类零件变形趋势、变形量及主要影响因素;采用改进加工方案,控制加工变形等方法减少梁类零件变形。结果表明:本文所提方法能够有效提升零件在加工过程中的平面度值,使梁类零件的变形得到明显改善。As a positioning reference part for wing assembly,how to effectively reduce the deformation of wing parts and improve the machining accuracy is an important task.A control method for the flatness warping deformation of wing beam parts during processing is proposed.Based on the technological characteristics of aircraft wing beam parts,the actual deformation data of the parts on the production site is computed,and the deformation trend,deformation amount and main influencing factors of beam parts are analyzed.The improved processing plan and processing deformation control method can reduce the deformation of beam parts.The results show that the flatness value of the parts in the process of machining can be effectively improved,and the deformation of beam parts can be significantly improved by the proposed method.
