摘要针对在大学中对机械制造工艺学这门基础课的学习成果的验收，在这次的毕业设计选题中，选择了针对杠杆（CA1340自动车床）加工工艺规程及其夹具设计的题目，通过对杠杆在CA1340自动车床上作用的分析、杠杆加工工艺的分析、杠杆的生产类型的分析，来确定杠杆（CA1340自动车床）的工艺工程和其加工夹具的设计方案。进而巩固所学知识，同时为日后的实践应用做一个良好的开端。关键词:机械工艺；加工工艺规程；夹具；杠杆AbstractInconnectionwithMachineryManufacturingTechnologyattheuniversitytolearnthisbasiccourselearningoutcomesacceptance,inthisgraduationdesigntopics,selectedforthesubjectoftheleverage(CA1340AutomaticLathe)processplanning,fixturedesigntopic,leverageintheroleoftheCA1340automaticlatheofanalysis,analysisoftheleverageprocess,analysisoftheleveragetypeofproduction,leverage(CA1340AutomaticLathe)technologytodeterminetheengineeringanddesignofmachiningfixtures.Therebystrengtheningtheknowledge,atthesametime,thishasagoodstartforfuturepracticalapplication.Keywords:Mechanicalprocess;Processplanning;Fixture;Leverage目录TOC\o"1-3"\u摘要PAGEREF_Toc327093831\hI第1章绪论PAGEREF_Toc327093832\h11.1机械制造工艺简介PAGEREF_Toc327093833\h11.2零件加工过程简介PAGEREF_Toc327093834\h2第2章零件的工艺分析及生产类型的确定PAGEREF_Toc327093835\h42.1零件的作用PAGEREF_Toc327093836\h42.2零件的工艺分析PAGEREF_Toc327093837\h42.3零件的生产类型PAGEREF_Toc327093838\h5第3章选择及确定毛坯，设计毛坯PAGEREF_Toc327093839\h63.1选择毛坯PAGEREF_Toc327093840\h63.2确定毛坯尺寸和公差PAGEREF_Toc327093841\h6第4章选择加工方法，制定工艺路线PAGEREF_Toc327093842\h84.1基面的选择PAGEREF_Toc327093843\h84.2零件表面加工方法的选择PAGEREF_Toc327093844\h84.3工艺过程制定PAGEREF_Toc327093845\h9第5章工序设计PAGEREF_Toc327093846\h115.1选择机床PAGEREF_Toc327093847\h115.2选择夹具PAGEREF_Toc327093848\h115.3根据不同工序选择刀具PAGEREF_Toc327093849\h125.4选择量具PAGEREF_Toc327093850\h135.5确定工序尺寸PAGEREF_Toc327093851\h15第6章确定切削用量及基本时间PAGEREF_Toc327093852\h19第7章夹具设计PAGEREF_Toc327093853\h367.1设计钻Φ4mm的油孔及锪Φ8mm圆锥沉头孔专用夹具PAGEREF_Toc327093854\h367.1.1定位方案PAGEREF_Toc327093855\h367.1.2装夹设计要求PAGEREF_Toc327093856\h377.1.3切削力和夹紧力的计算PAGEREF_Toc327093857\h377.1.4导向元件PAGEREF_Toc327093858\h387.1.5夹具与机床连接元件PAGEREF_Toc3
