摘 要
此畢業(yè)設計的課題是“汽車主動傘齒輪”的工藝工裝設計。其中介紹了主動傘齒輪從毛坯變成成品的一個完整的機械加工過程，此書包含了機械加工工藝規(guī)程的制定，專用夾具設計，專用刀具設計，專用量具設計四章主要內容。
第一章介紹了此零件的工藝分析，加工類型，選定毛坯并且制定了加工工藝。
第二章為此設計書的重點章節(jié)，本書以兩套專用夾具為例，詳細的闡述了典型工序中的專用夾具的設計過程。其中包括了夾具功能簡圖和工作原理，夾具的定位方案設計（定位方式、元件等），夾具的定位誤差分析，切削力及夾緊力的計算，夾具的夾緊裝置或機構設計，夾具動力裝置設計。通過對此章的閱讀，可以詳細了解夾具的設計方法和過程，并且可以當作典型例子去應用到其他零件的機械加工工藝中的夾具設計。
第三章為專用道具設計，第四章為專用量具設計，其中有詳細步驟及公式，多可以借鑒此章進行設計。
通過對此書的閱讀，可以獨立完成汽車傘齒輪的工藝工裝設計，可以說此書是汽車主動傘齒輪工藝工裝設計的專用機械加工手冊

Abstract
This graduation project topic is the design of “the automobile driving bevel gear” craft work clothes. Introduced a completed machine-finishing process that the driving bevel gear turns the end product from the semifinished materials. This book contained four chapter of primary coverages that is the machine-finishing technological process formulation, the unit clamp design, the special-purpose cutting tool design, the special-purpose measuring instrument designs.
First chapter introduced this components craft analysis, the processing type, the designation semifinished materials and formulat the processing craft.
The second chapter is the key chapter of this book.This book take two grip designs s as an example.It expound detailed design two grips in a model of a production processes.It contains the photo of the grip function , design a way for locating the grip(a way for locating, element and so on).,the positioning error analysis of the fixrture, the calculation of cutting force and the clamping force , the clamping device or mechanism design of fixtures, the power plant design of Fixture. Through reading this chapter, you can learn more about the fixture design methods and processes, and can act as a typical example to apply to design other parts of the machining process in the fixture design field.
Chapter III as props for the design, chapter IV for measuring tool for the design, including the detailed steps and formula, most of the design can be draw on this chapter.
Through reading this book, you can complete an independent automotive bevel gear technology tooling design, the book is the vehicle that can take the initiative to bevel gear technology Equipment designed for manual machining.
