擺線齒輪泵外轉(zhuǎn)子加工工藝及主要工裝設計說明書.doc

I摘要本文就擺線的基本概念作了介紹，并闡述擺線齒輪泵中，外轉(zhuǎn)子的加工工藝過程、工裝設備以及成形拉刀的設計計算。擺線齒輪泵中以內(nèi)轉(zhuǎn)子為主動輪，外轉(zhuǎn)子為從動輪，在設計中要求外轉(zhuǎn)子精度高，同時考慮到經(jīng)濟成本，在設計加工工藝時，盡量采用既高精度又經(jīng)濟的方式。而且還介紹了在單件生產(chǎn)綱領下，進行擺線齒輪泵外轉(zhuǎn)子曲面磨削的方法。確定了磨削參數(shù)及工藝裝備。本加工方法具有傳動鏈短，砂輪修磨簡單，可穩(wěn)定的保持加工精度。關(guān)鍵詞：擺線齒輪外轉(zhuǎn)子；工藝；結(jié)構(gòu)設計；工裝設備；成形拉刀。IIAbstractThisarticleintroducedthebasicconceptofcycloidandcycloidgearpumpdescribed,theouterrotorofthemachiningprocess,toolingequipmentanddesigncalculationofformingbroach.Withintherotorcycloidalgearpumpforthedrivingwheel,outerrotortothedrivenwheel,therotorinthedesignrequirementsofhighprecision,takingintoaccounteconomiccosts,inthedesignprocess,trytousethehigh-precisionandeconomicalway.Butalsointroducedtheprograminthesingleproductionunderthecycloidgearpumpouterrotorsurfacegrindingmethod.Determinetheparametersandprocessesofgrindingequipment.Thisprocessingmethodhasashorttransmissionchain,grindingwheelsimple,steadyandprecisionKeywords:cycloidalgearouterrotor；process；structuraldesign；toolingequipment；formingbroachIII目錄摘要.I第1章緒論.11.1齒輪泵概述.11.2齒輪泵發(fā)展趨勢.11.3外轉(zhuǎn)子設計的基本要求.3第2章外轉(zhuǎn)子的加工工藝設計.42.1零件的分析.42.1.1零件的作用.42.1.2零件工藝分析.42.2工藝規(guī)程設計.42.2.1確定毛坯的制造形式.42.2.2基面的選擇.52.2.3制定工藝路線.52.2.4機械加工余量，工序尺寸及毛坯尺寸確定.7第3章夾具設計.183.1拉胎.183.1.1問題的提出.183.1.2定位基準的選擇.183.1.3定位誤差分析.183.1.4夾緊力.183.1.5胎具結(jié)構(gòu).183.2磨胎.183.2.1問題的提出.183.2.2定位基準的選擇.193.2.3夾具結(jié)構(gòu).193.3磨頭.22IV3.4打磨砂輪工具.23第4章內(nèi)曲面成形拉刀設計.234.1粗拉刀設計.234.1.1切削部設計.234.1.2校準部設計.294.1.3其它部分及拉刀總長度.304.1.4拉刀強度計算及拉削力的校驗.334.2精拉刀設計.344.2.1參數(shù)選擇.344.2.2校核最大拉削力maxF.374.2.3拉刀強度校驗.374.2.4拉刀總長度L.37結(jié)束語.40致謝.41參考文獻.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.52.2.4Machiningallowance,processtodeterminethesizeandroughsize.7ChapterThreeFixtureDesign.183.1Pulltire.183.1.1Proposedoftheproblems.183.1.2Thechoiceoflocatingdatum.183.1.3Orientationerror.183.1.4Clampingforce.183.1.5Moldstructure.183.2Tirewear.183.2.1Proposedoftheproblems.183.2.2Thechoiceoflocatingdatum.193.2.3FixtureStructure.193.3Grindinghead.22
