大型水轮机顶盖底环轴孔加工系统开发与应用

The Development and Application of Axle Hole Machining System on Large Turbine Head Cover-bottom Ring

本文针对大型水轮机顶盖底环轴孔数控加工的关键技术,提出了基于边心距和弦距误差消除匹配算法的工艺方案。根据该工艺方案,采用C#作为开发语言,完成大型水轮机顶盖底环轴孔加工系统的设计和测试,最终完成该加工系统的开发。经实际加工检验,该系统能高效解决顶盖底环整圆结构、分瓣结构轴孔加工同轴度的问题,具有一定的经济效益。

This paper introduces the key technology of nc machining of the top of large water turbine,puts forward the method of eliminating the matching algorithm based on the margin error.According to the process,using C#as the development language,the design and testing of head cover-bottom ring axle hole system,eventually the development of the processing system is completed.By actual processing testing,the system can efficiently solve the problem of the head cover-bottom ring axle hole,including the whole circle structure and split structure,which generates a certain economic benefits.
