摘要 Abstract The topic of my thesis is the design of machining technics regulatious and appropriative clamp of the box body of engine .The box of engine is the basic spare of machine,it conecs the staik,set,wheel gear…etc of engine to the whole.And accurate position to transfer torque or complete prescriptive movement.The machining quality of the box body of engine will influence the performance,precision an life of machine. According to the plan and didactical brief made by machine manufacturing craft profession committee,this design have mainly compiled and designed teachining technics regulations and appropriative clamp using professional theory and practical knowledge.This design is not only a great chanllenge,but also a good exercise for our graduate.It has enhanced our lever of speciality,at the same time,it also has cultived our team sprint. The design mainly introduces the spare parts craft process,tongs technological design to make comparison system,analysis and argumen integrity.Design craft regulations to make expation,and establishment reasonable of process craft route.In this design,I have analysed and calculated some key working proces,which include the remaining quantity of process,the measure of working procedure procedure the tolerance of working procedure techics cards.Whatmore in the end ,I have designed a appropriative clamp proof-tested its precision to ensure the quality of workpiece. Key word: machining quality; the techics of machining; clamp; working procedure; the remaining quantity of maching; the measure of working procedure 目 录 第一章 绪论 1 1.1 课题研究的意义及现状 1 1.1.1 发动机的工作原理 1 1.1.2 发动机的结构 1 1.1.2 课题研究的现状及展望 2 1.2 论文主要研究内容 2 第二章 发动机箱体工艺设计 3 2.1箱体的分析 3 2.1.1箱体的功用分析 3 2.1.2计算生产纲领 确定生产类型 3 2.1.3箱体结构和功用的分析 4 2.1.4箱体的技术分析 4 2.1.5箱体的材料分析 5 2.2发动机箱体毛坯的设计 6 2.2.1确定毛坯种类及加工方法的选择 6 2.2.2毛坯
