摆线齿轮泵外转子加工工艺及主要工装设计说明书.doc -- 12 元

I摘要本文就摆线的基本概念作了介绍，并阐述摆线齿轮泵中，外转子的加工工艺过程、工装设备以及成形拉刀的设计计算。摆线齿轮泵中以内转子为主动轮，外转子为从动轮，在设计中要求外转子精度高，同时考虑到经济成本，在设计加工工艺时，尽量采用既高精度又经济的方式。而且还介绍了在单件生产纲领下，进行摆线齿轮泵外转子曲面磨削的方法。确定了磨削参数及工艺装备。本加工方法具有传动链短，砂轮修磨简单，可稳定的保持加工精度。关键词摆线齿轮外转子工艺结构设计工装设备成形拉刀。IIAbstractThisarticleintroducedthebasicconceptofcycloidandcycloidgearpumpdescribed,theouterrotorofthemachiningprocess,toolingequipmentanddesigncalculationofformingbroach.Withintherotorcycloidalgearpumpforthedrivingwheel,outerrotortothedrivenwheel,therotorinthedesignrequirementsofhighprecision,takingintoaccounteconomiccosts,inthedesignprocess,trytousethehighprecisionandeconomicalway.Butalsointroducedtheprograminthesingleproductionunderthecycloidgearpumpouterrotorsurfacegrindingmethod.Determinetheparametersandprocessesofgrindingequipment.Thisprocessingmethodhasashorttransmissionchain,grindingwheelsimple,steadyandprecisionKeywordscycloidalgearouterrotorprocessstructuraldesigntoolingequipmentformingbroachIII目录摘要...................................................................I第1章绪论.............................................................11.1齿轮泵概述......................................................11.2齿轮泵发展趋势..................................................11.3外转子设计的基本要求............................................3第2章外转子的加工工艺设计..............................................42.1零件的分析......................................................42.1.1零件的作用...............................................42.1.2零件工艺分析.............................................42.2工艺规程设计....................................................42.2.1确定毛坯的制造形式.......................................42.2.2基面的选择...............................................52.2.3制定工艺路线.............................................52.2.4机械加工余量，工序尺寸及毛坯尺寸确定.....................7第3章夹具设计.........................................................183.1拉胎...........................................................183.1.1问题的提出..............................................183.1.2定位基准的选择..........................................183.1.3定位误差分析............................................183.1.4夹紧力..................................................183.1.5胎具结构................................................183.2磨胎...........................................................183.2.1问题的提出..............................................183.2.2定位基准的选择..........................................193.2.3夹具结构................................................193.3磨头...........................................................22IV3.4打磨砂轮工具...................................................23第4章内曲面成形拉刀设计...............................................234.1粗拉刀设计.....................................................234.1.1切削部设计..............................................234.1.2校准部设计..............................................294.1.3其它部分及拉刀总长度....................................304.1.4拉刀强度计算及拉削力的校验..............................334.2精拉刀设计.....................................................344.2.1参数选择................................................344.2.2校核最大拉削力maxF......................................374.2.3拉刀强度校验............................................374.2.4拉刀总长度L............................................37结束语..................................................................40致谢...................................................................41参考文献................................................................42VCONTENTSAbstract...........................................................................................................................................................IIChapterOneIntroduction......................................................................................................................11.1GearPumpOverview...........................................................................................................11.2DevelopmentTrendofgearpump......................................................................................11.3Thebasicrequirementsofexternalrotordesign...............................................................3ChapterTwoExternalrotordesignprocess........................................................................................42.1Partsoftheanalysis...............................................................................................................42.1.1Partsoftherole.........................................................................................................42.1.2PartsProcessAnalysis.............................................................................................42.2Processplanning....................................................................................................................42.2.1Determinetheformofblankmanufacturing.......................................................42.2.2Thechoiceofthebasesurface...............................................................................52.2.3Developmentofprocessroutes...............................................
