中文摘要:
      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。
英文摘要:
      As a positioning reference part for wing assembly, how to effectively reduce the deformation of wing parts and improve the machining accuracy has always been an important task. According to the accumulated data analysis of the part, its deformation is mainly reflected in the saber bend, length extension and flatness warpage. This paper proposes a control method for the flatness warping deformation of wing beam parts during processing. It is mainly based on the technological characteristics of aircraft wing beam parts to analyze the actual deformation data of parts on the production site, determine the deformation trend, deformation amount and main influencing factors of beam parts. Then by improving the processing plan and controlling the processing deformation, the deformation of beam parts can be reduced to achieve the purpose of improving accuracy. 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 method proposed in this paper.
