安徽建筑大学（毕业设计）毕业设计(论文)专业机械设计制造及其自动化班级学生姓名学号课题法兰盘工艺规程及专用夹具计算机辅助设计指导教师摘要工艺学是以研究机械加工工艺技艺和夹具设计为主技术学科，具有很强的实践性，要求学习过程中应紧密联系实践生产，同时它又具有很强的综合性。安徽建筑大学（毕业设计）本次毕业设计的课题是法兰盘机械加工工艺及其专用夹具设计，主要内容如下：首先，对零件进行分析，主要是零件的作用分析和工艺分析，通过零件分析可以了解零件的基本情况，而工艺分析可以了解零件的加工表面和加工要求，根据零件图提出的加工要求，确定毛坯的制造形式和尺寸。第二步，进行基面的选择，确定加工过程中的粗基准和精基准。根据选好的基准，制定工艺路线，通常制定两种以上的工艺路线，通过工艺方案的比较和分析，再选择可以使零件的几何形状、尺寸精度及位置精度等技术要求得到合理的保证的一种工序。第三步，根据已选定的工艺路线，确定每一步的切削用量和切削工时，并选择合适的机床和刀具。对于粗加工还要校核机床功率。最后，设计第三道工序——钻法兰盘孔的夹具。先提出设计问题，再选择定位基准，然后开始切削力和夹紧力的计算和定位误差的分析。然后把设计的过程整理为图纸。通过以上的概述，整个设计基本完成。关键词加工工艺；夹具设计安徽建筑大学（毕业设计）AbstractAspecializedmainspecializedcoursethat“mechanicalmanufacturingengineeringisstudied”ismachinery,relymainlyonstudyingmachiningtechnologyandjigtodesigntechnologicaldiscipline,haveverystrongpracticality,requirethatshouldcontactproductionpracticescloselyinthelearningprocess,atthesametimeithascomprehensivetheverystrongonethesubjectofthisgraduationprojectisflangeprocessingtechnologyrulesandspecial-purposejigofacertainprocessaredesigned,themaincontentisasfollows:Firstofall,analysis,itismainlyanalysisofthefunctionofthepartandcraftanalysistothepart,thoughpartanalysiscanfindoutaboutbasicsituationofpart,andcraftanalysismayknowtheprocessingsurfaceofthepartandisitrequiretoprocess.Theprocessingdemandputforwardaccordingtothepartpicture,confirmthemanufactureformoftheblankandsurenessofthesize.Thesecondstep,carryonthechoicethebase,confirmthickdatumandprecisedatumintheprocessingcourse.Accordingtothedatumchosen,makethecraftroute,usuallymakethecraftrouteofmorethantwokinds,Withanalysisthroughthecomparisonofthecraftscheme,andthenchoosingbeabletomakesuchspecificationrequirementsasthePrecisionofgeometryform,sizeofthepartandprecisionofposition,etc.Getakindofprocessoftherationalassurances.Thethirdstep,accordingtothealreadyselectedprocessroute,confirmforeverystepsofcuttingconsumptionandbasicman-hour,choosesuitablelatheandcutter.Toroughmachining,willcheckthepowerofthelathe.Finally,designthethirdprocess-thejiggettingintotheholeoftheringflange.Putforwardthequestionofdesigningfirst,andthenchoosetoorientthedatum,thenthelocalizationerror.Thenputthedesigncourseinorderasthedrawing.Throughthesummaryoftheabove,designandfinishbasicallyentirely.Keywords:Processthecraft;Thetongsdesign安徽建筑大学（毕业设计）目录摘要................................................................................................................................2Abstract..........................................................................................................................3目录................................................................................................................................41.绪论..............................................................................................................
