1、l Southwest university of science and technology 本科毕业设计(论文) 核电大叶片用液压快速装夹传动盘的设计核电大叶片用液压快速装夹传动盘的设计 学院名称制造科学与工程学院 专业名称机械设计制造及其自动化 学生姓名 学号20097208 指导教师 高工 二一三年六 l 核电大叶片用液压快速装夹传动盘的设计 摘要:叶片加工过程中,一些叶片汽道型面较长且出汽侧较薄,在这样的工件上加 工容易出现变形及颤动,这样就出现质量控制难的问题,于此特设计一种液压自动控 制、浮动拉伸、快速装夹的传动盘,从而提高产品合格率,减少操作人员劳动强度, 实现自动控制,缩短
2、其生产周期,降低其生产成本,并且其结构强度也完全能满足使 用。 由于传动盘需要连接机床主轴或尾座,且需要具有夹具定位和夹紧功能,故传动 盘应具有传递动力和定位、夹紧功能。因此,特设计两部分结构,一部分为传动盘体, 另一部分为夹具体,并将两者连接,从而满足功能需求。 根据所需功能和结合现有的使用情况及工件加工公差,从而选用恩派克公司的工 模具液压成套解决方案的产品,由此选用摆动油缸、弹簧支撑油缸、油路块油缸等液 压元件,并根据所设计的液压系统图组装传动盘。同时,根据液压系统图、夹具功能 要求、设计经验、精度要求、定位基准和相关计算等,设计夹具体的结构,同时相应 地设计传动体的结构。设计中通过相关
3、实验获得重要数据。设计结束后,通过评审, 制定加工工艺,试制产品,并实验修正,最后大量生产。 关键词:叶片;传动盘;液压自动控制;合格率; l Design of nuclear power blade with hydraulic quick clamping drive disk Abstract:Blade machining process, some road-surface steam leaves the steam side is long and thin, in such a workpiece machining prone to distortion and vibra
