摘 要 涡轮盘是十分重要的零件，它的精度高、机械加工难度大，在整个涡轮机加工中也是一个难点。而在涡轮盘机械加工中，工作量最大、难度最高的是榫槽加工。涡轮盘Abstract The turbine disk is on the aircraft engine the extremely important components, for its high precision, the hard machine-finishing, under the high speed high temperature environment works, is the key complex component, in the entire turbine processing also is a difficult point. Moreover in the turbine disk machine-finishing, the turbine disk trough processing is what the work load is biggest, the difficulty is highest. The turbine disk trough fixture may guarantee the processing precision is high, enhances the processing efficiency. Therefore the fixture design in trough processing is an important link. This article through to analysis the turbine disk trough type structure, the processing craft, the fixture design and the service condition, elaborated the localization datum choice, contracts the way the determination, the correct complex spatial size and the angle computation and the high accuracy ruling engine construction design process, has completed the designing of the turbine disk trough important fixture work clothes, proposed the solution of enhances trough the surface roughness in view of the overall craft equipment. Key words：trough the working surface spatial angle computation speed step type double sells the linkage axial to be divided the equipment 目 录 摘 要……………………………………………………………………………I Abstract …………………………………………………………………………II 第1章 绪 论……………………………………………………………………1 1.1 机床夹具及其功用 …………………………………………………1 1.2 现代机床夹具的发展方向 …………………………………………1 1.3 现代工业对夹具设计的基本要求 …………………………………2 1.4 项目提出的背景 ……………………………………………………2 1.5 项目研究的方法、预期结果及意义 ………………………………3 第2章 涡轮盘榫槽加工特点与工艺装备 ……………………………………4 2.1 涡轮盘榫槽的加工特点 ……………………………………………4 2.2 拉削特点 ……………………………………………………………4 2.3 拉削分类 ……………………………………………………………4 2.4 拉削速度 ……………………………………………………………5 2.5 拉削表面粗糙度 ……………………………………………………5 2.6 工艺装备 ……………………………………………………………6 第3章 涡轮盘液压立拉夹具的设计 …………………………………………7 3.1 设计方案的确定 ……………………………………………………7 3.1.1 任务来源与
