车床尾座体工艺规程制订及工装设计
摘要
尾座体是车床上的重要的部件之一，是车床上用以支撑轴类零件车削加工和实施钻孔的主要车床附件。本文针对某类给定的尾座体进行了加工工艺与工装的设计，完成了以下工作：
1. 概述了尾座体的技术和现状发展；
2. 对尾座体进行了工艺分析，并提出了两种方案进行比较；
3. 编制了尾座体的工艺规程，完成了其工序卡的设计；
4. 针对工艺中的某重要工序，设计完成了一套镗孔夹具，包括定位元件，夹紧机构、对刀块、夹具体的设计并分析了定位误差。

Lather tail the craft work of the body pack a design

Abstract
stalk spare parts, the car pares to process the main lather enclosure that drills a hole with implementation.This text aims at a certain the tail body giving certainly carried on to process the design that craft and work pack and completed once work:
1．All said a tail the technique and present condition development of the body;
2．Carried on craft analysis to the tail body, and put forward two kinds of projects to carry on a comparison;
3．Drew up a tail body of craft regulations, completed the design of its work preface card;
4．Aim at a craft in of some important work preface, designed to complete a set of Xian slot tongs, including fixed position component, clipped tight organization, to the knife piece, clip a concrete design and analyzed a fixed position error margin.
