尾透主轴叶片锁紧槽加工工艺的改进

Improvement of Processing Technology of Locking Groove for Blade on Tail Turbo-expander Shaft

针对主轴四级新型榫槽加工制造的独特化,分析其特殊材质、非标刀具、加工程序、检测工具等给实际加工带来困难的原因,形成一套从加工到检测的新工艺方法,解决了尾透主轴叶片锁紧组装配难的问题。

Aiming at the uniqueness of machining and manufacturing the spindle four stage new type groove,this paper finds that the main reasons affecting assembling are mainly concentrated in the special material,the cutting tool,precessing method and measurement tool.This paper proposes an improved processing method of the locking groove,which is a very good solution to the locking block assembly problem and has been applied in practice.
