摘要

本设计研究分析的主要内容为调速杠杆的加工工艺和设计制作调速杠杆的铣床专用夹具，分析原始资料并最终用UG软件进行夹具的三维制图。

本设计总体分为三部分：调速杠杆的加工工艺编制、铣床专用夹具设计、铣床专用夹具三维设计，其中机械加工是作为推动社会发展和经济建设的重要技术，加工工艺是保证产品质量的基础条件，铣床在机械零件加工过程中使用比较广泛,在加工杆类零件时,通用夹具比如虎钳、卡盘很难满足夹紧要求,影响加工效率,故本设计加工采用专用夹具，设计调速杠杆的铣床专用夹具则可以有效提高加工效率和加工精度，三维制图根据夹具设计方案,把设计好的定位元件、夹紧元件以及各部分元件建立草图，拉伸建模，最终按照装配关系依次装配。
