摘要

本课题设计的是车床尾座顶尖套筒零件的数控工艺及实施,主要设计任务是车床尾座顶尖套筒零件的数控加工工艺设计、编制加工程序说明卡、主要工序加工工序卡、工装夹具的设计、绘制工装（夹具）装配图及主要零件图、重要工序数控加工程序编制、数控仿真模拟加工。通过本课题的设计，不仅为企业解决了生产上的实际问题，如铣床上铣车床尾座顶尖套筒键槽的装夹方案，同时也掌握了一系列机械加工设计方法及步骤，进一步提高了机械设计的综合能力，为以后走上机械专业岗位奠定了良好的基础。

随着CAD/CAM软件技术的进一步发展，几乎所有的个性化产品设计都在CAD 软件中设计完成.并与CAM软件结合使三维造型出来的产品可以直接生成ＮＣ代码。这样使产品开发到产品出货的周期大大缩短，是现代制造业发展的必然趋势。关键词：套筒、工艺、工装设计、数控程序

Abstract

What this topic design is the lathe tailstock apex sleeve components numerical control craft and the implementation, the main task of design is the lathe tailstock apex sleeve components numerical control processing technological design, the establishment processing program showed that the card, the main working procedure processing travel chart, the work clothes jig's design, draws up the work clothes (jig) the assembly drawing and the main detail drawing, the important working procedure numerical control processing program establishment, the numerical control simulation simulation processing. Through this topic design, not only has solved in the production actual problem for the enterprise, if on the milling machine the milling machine tail block place apex sleeve key slot's attire clamps the plan, simultaneously has also mastered a series of machine-finishing design method and the step, further sharpened the machine design synthesizing capacity, will step onto the machinery specialized post for later to lay the good foundation.

Along with the CAD/CAM software technique's further development, the nearly all personalization product design designs in the CAD software completes. And enables the product which with the CAM software union the three dimensional modelling comes out to be possible to produce the NC code directly. Like this causes the cyclical big reduction which the product development product produces goods, is the modern manufacturing industry development inevitable trend

Key word: Sleeve, craft, work clothes design, numerical control procedure
