摘要
为提高大型水轮机进口筒形阀改造加工效率,减轻加工难度,同时保证各部零件装配的精度要求,本文提出一种筒形阀改造加工方法。通过改进加工工艺、设计专用辅助工装夹具结合工艺参数的优化,实现了关键配合面的自动化加工,在保证筒形阀装配的尺寸精度与形位精度的同时,极大简化加工的流程、缩短改造周期,减少了传统依赖高技能人工的刮研作业量,成功解决了大型薄壁水轮机进口筒形阀结构改造现场加工的技术难题。
In order to enhance the processing efficiency of large-scale hydro turbine inlet spherical valve modification and reduce the processing difficulty,while ensuring the assembly accuracy of various components,this paper proposes a modification processing method for spherical valves.By improving the processing technology,designing special-purpose auxiliary fixtures and optimizing process parameters,the automated processing of key mating surfaces is achieved.This method ensures the dimensional and positional accuracy of spherical valve assembly.At the same time,it greatly simplifies the processing procedure,shortens the modification cycle,reduces the traditional reliance on high-skilled manual scraping work,and successfully solves the technical problem of on-site processing of structural modification of large-scale thinwalled hydro turbine inlet spherical valves.
