抽油泵長缸套內(nèi)孔加工工裝設(shè)計說明書.doc

I摘要抽油泵長缸套是抽油泵的主要基礎(chǔ)件。抽油泵工作性能主要取決于柱塞和泵套加工精度、表面質(zhì)量及形狀精度。本文討論了在現(xiàn)有的加工條件下完成對抽油泵長缸套內(nèi)孔的加工，即深孔加工，提出了車床改造的方案。簡單介紹了深孔的發(fā)展概況、深孔加工系統(tǒng)的組成、深孔加工中的常見問題?；谝陨咸攸c(diǎn)，設(shè)計完成對CA6140的深孔加工改造。原來的鏜滾壓符合工具在加工結(jié)束移動溜板拉出工件時會在工件表面留下拉傷痕跡，影響工件表面質(zhì)量及精度，且前端鏜刀刀尖也比較容易損壞，因此我也對鏜滾壓復(fù)合工具進(jìn)行了一些改進(jìn)。改進(jìn)后的鏜滾壓復(fù)合工具的結(jié)構(gòu)變的比較簡單，快退時不會拉傷工件表面，鏜刀刀尖不易損壞，加工質(zhì)量穩(wěn)定，生產(chǎn)效率明顯提高。關(guān)鍵詞深孔加工鏜滾壓復(fù)合工具鏜床車床改裝IIAbstractCylinderjacketisthemainfoundationalpart.Theworkingperformanceofoil-wellpumpismainlydecidedonthecompoundperformanceofplungerandcylinderjacket.Thatistosay,itisdependedonthecylinderjacketworkingaccuracyroughnessofsurfaceandpositionaccuracy.Thispaperdiscusseshowtocompletethetraditionaldepthaperturecutting,thesystemoforificecuttingandtheproblemsthatappearintheorificeprocessingissimplydiscuaaed.Baseonsuchcharacters,designandcompletetheorificemachiningalterationinthetypeofCA6140.Theoriginalboring-stitchtoolswillleftsprainontheworkpiecesurfacewhenprocessingisoverandthemobileslidepullouttheworkpiece.Thiswillaffecttheworkpiecesurfacequalityandprecisionandthetipofthefrontboringisrelativelyeasytodamage,soIhavetomakesomeimprovementsontheboring-stitchtools.AfterImproved,theboring-stitchtoolsstructurearerelativelysimple,quickwithdrawalwillnotpulltheworkpiecesurface,processingqualityisstableandproductionefficiencyisimprovedsignificantly.Keywordsorificeworkboring-stitchtoolsboringmachineIII目錄摘要.Abstract.第1章緒論.11.1車床改裝為深孔加工的意義.11.2深孔加工技術(shù)研究概述.11.2.1深孔的定義.11.2.2深孔加工的類型、特點(diǎn)及要解決的主要問題.21.2.3深孔加工發(fā)展概況.41.3常用深孔加工系統(tǒng)及系統(tǒng)中的常用裝置.61.4深孔加工技術(shù)的研究動態(tài).81.5深孔的鏜滾壓加工.121.5.1深孔鏜削加工.121.5.2深孔滾壓加工.14第2章深孔加工工裝設(shè)計.172.1概述.172.1.1深孔加工要求.172.1.2簡述.182.1.3車床改造總體方案.192.2車床改造分析與計算.202.3機(jī)床改造結(jié)構(gòu)設(shè)計.212.3.1鏜滾壓切削設(shè)計.222.3.2定位、夾緊裝置的設(shè)計.242.3.3授油器的結(jié)構(gòu)設(shè)計.292.3.4冷卻排屑系統(tǒng)結(jié)構(gòu)設(shè)計.292.4.5鏜桿的設(shè)計.312.3.6鏜桿固定架設(shè)計.322.3.7壓板設(shè)計.33結(jié)論.34致謝.35參考文獻(xiàn).36IVContentsAbstract.Chapter1Introduction.11.1Lathemodifiedforthedeepholeprocessingsignificance.11.2Thedeepholeprocessingtechnologyresearchpaper.11.2.1Definitionofdeephole.11.2.2Thedeepholeprocessingthetype,characteristicsandtheimportantproblemtobesolved.21.2.3Thedeepholeprocessingdevelopmentsituation.41.3Commonlyusedthedeepholeprocessingsystemandthesystemofcommondevice.61.4Thedeepholeprocessingtechnologytrendsofresearch.81.5Deepholeboringrollingprocessing.121.5.1Deepholeboringcutprocessing.121.5.2Deepholerollingprocessing.14Chapter2Thedeepholeprocessingequipmentdesign.172.1Ofalmost.172.1.1Thedeepholeprocessingrequirements.172.1.2This.182.1.3Theoveralldesignofthelathetransformation.192.2Lathetransformationanalysisandcalculation.202.3Machinetoolsstructuredesign.212.3.1Boringrollingcuttingdesign.222.3.2Positioning,clampingdevicedesign.242.3.3Grantedthestructuredesignoftheoilpot.292.3.4Coolingscrapsdischarges
