专用机械传动轴的加工工艺流程设计摘要机械加工工艺流程设计能力是从事机械制造专业的科研、工程技术人员必须具备的基本素质之一。机械加工工艺流程设计作为高等工科院校教学的基本科目，在实践中占有极其重要的地位，工艺流程设计在加深对专业课程基本理论的理解和加强对解决工程实际问题的能力培养方面所发挥的作用是显而易见的。本设计是传动轴的加工工艺流程设计，其结构虽然规则，但是精度要求比较高，所以工艺要求比较复杂。需要粗车、数车、铣车、磨销，其中数车是加工关键。数控车床加工工艺是以机械制造中的工艺基本理论为基础，结合数控车床的特点，综合运用多方面的知识解决数控车床加工过程中面临的工艺问题。工艺流程是保证机械产品高质量、低成本的一种重要的工艺依据，工艺流程设计在机械加工中就显得更为突出，因此中小型零件加工的流程设计常被选作毕业设计的主要内容之一。关键词：传动轴，工艺流程，粗车，数控车床，编程THEDESIGNOFDRIVESHAFTMACHINTNGPROCESSABSTRACTTheabilityofmachine-finishingprocessdesignisoneofthebasicabilitieswhichthemachinerymanufacturespecializedscientificresearcher,engineersandtechniciansareengagedinmustbehave.Themachine-finishingprocessdesignasabasicalsubjectthatallthehigherengineeringcoursecollegesanduniversitiesteachingtook,holdingtheextremelyimportantpositioninthepractice.Themachine-finishingprocessdesignhasasignificantlyfunctionwhichisdeepeningonthespecializedcurriculumelementarytheoryunderstandingandstrengtheningtheabilitytosolvethefunctionthattheprojectactualproblem.Thisdesignisdriveshaft'smachine-finishingprocessdesign，it’sstructureisrule,buttheaccuracyrequirementisquitehigh.needingroughturning,NCprocessing,milling,grinding,andNCprocessingisthekey.CNCprocessingmachineryisintheprocessbasedonthebasictheory,combiningthecharacteristicsofCNC,comprehensiveuseofvariousaspectsofknowledgetosolveCNCintheprocessoffacingtheproblem.Themachine-finishingprocessdesignisanimportantcraftbasisthatguaranteehighgrade,lowcostmachine-finishing.Theprocessdesignappearsmoreprominentinthemachine-finishing,thereforemiddleandsmallscalecomponentsmachine-finishingprocessdesignisselectedfrequentlytodograduationproject.KEYWORDS：driveshaft，technicalprocess，roughturning，CNC，programming目录前言...............................................................................................1第1章零件分析..................................................................2§1.1计算生产纲领，确定生产类型...........2§1.2轴类零件的作用、分类及技术要求2§1.3工艺分析.....................................................................5第2章工艺流程设计.....................................................7§2.1确定毛坯制造形式及尺寸........................7§2.2基准的选择...............................................................7§2.2.1粗基准的选择..................................................7§2.2.2精基准的选择..................................................8§2.3主要工序加工方法............................................8§2.4工艺流程的拟定...............................................10第3章工序设计...............................................................13§3.1选择加工设备和工艺设备.....................13§3.1.1选择机床............................................................13§3.1.2选择夹具............................................................13§3.1.2选择刀具............................................................13§3.1.3选择量具..............................................................
