普通X62W銑床的數(shù)控化改造設(shè)計(jì)I鄭州科技學(xué)院本科畢業(yè)設(shè)計(jì)（論文）題目普通X62W銑床的數(shù)控化改造設(shè)計(jì)學(xué)生姓名李博專業(yè)機(jī)械設(shè)計(jì)制造及其自動(dòng)化班級(jí)08級(jí)本科（6）班學(xué)號(hào)200833164院（系）機(jī)械工程學(xué)院指導(dǎo)教師（職稱）朱永剛暢靜文（講師）完成時(shí)間2012年5月16日普通X62W銑床的數(shù)控化改造設(shè)計(jì)II普通X62W銑床的數(shù)控化改造設(shè)計(jì)摘要我所設(shè)計(jì)的畢業(yè)課題為“普通銑床數(shù)控化改造設(shè)計(jì)”。對(duì)于機(jī)床的設(shè)計(jì)來說，我首先對(duì)所要設(shè)計(jì)的機(jī)床進(jìn)行技術(shù)調(diào)查，查閱了國(guó)內(nèi)外有關(guān)文獻(xiàn)資料，在此基礎(chǔ)上，對(duì)其用途范圍、性能指標(biāo)、方案對(duì)比等進(jìn)行論證分析。對(duì)于通用機(jī)床我更是查閱了大量的國(guó)內(nèi)外有關(guān)銑床的資料后，擬定了此機(jī)床的總體方案為立式銑床。本文在X62W數(shù)控銑床改造設(shè)計(jì)時(shí)主要從經(jīng)濟(jì)性、方便性、實(shí)用性、可靠性四方面因素出發(fā)，對(duì)X62W型銑床進(jìn)行了數(shù)控銑床機(jī)械系統(tǒng)設(shè)計(jì)，硬件及電路設(shè)計(jì)。使改造后的機(jī)床的機(jī)械傳動(dòng)部分具有高靜態(tài)、動(dòng)態(tài)剛度；運(yùn)動(dòng)副之間的摩擦因數(shù)小，傳動(dòng)無間隙；功率大；便于操作和維修。X62W數(shù)控銑床機(jī)械系統(tǒng)設(shè)計(jì)包括伺服驅(qū)動(dòng)系統(tǒng)的設(shè)計(jì)計(jì)算，滾珠絲杠螺母副的設(shè)計(jì)計(jì)算。進(jìn)給傳動(dòng)系統(tǒng)設(shè)計(jì)中，拆除縱向、橫向、垂向進(jìn)給箱齒輪，在該處將手輪軸通過一對(duì)減速齒輪和縱向、橫向及垂向步進(jìn)電機(jī)相連。數(shù)控系統(tǒng)是一個(gè)基于8031單片機(jī)的數(shù)字型控制系統(tǒng)。采用較小體積的單片機(jī)來實(shí)現(xiàn)一般的邏輯功能，對(duì)進(jìn)給系統(tǒng)的兩個(gè)軸進(jìn)行控制。關(guān)鍵詞：數(shù)控化改造；定位精度；步進(jìn)電機(jī)；滾珠絲杠；伺服傳動(dòng)系統(tǒng)普通X62W銑床的數(shù)控化改造設(shè)計(jì)IIIORDINARYX62WMILLINGMACHINEOFTHERETROFITDESIGNOFTHENUMERICALCONTROLABSTRACTIdesignofgraduationprojectforordinarymillingmachinenumericalcontroltransformationdesign.Forthemachinetooldesign,Ifirstwanttodesignofmachinetooltechnologyresearch,consultingliteratureathomeandabroad,onthebasisofthis,theapplicationscope,performanceindex,schemecomparisonandanalysis.ForuniversalmachineIwasreferringtoalargenumberofdomesticandinternationalrelevantmillingmachineinformation,formulatetheoverallplanfortheverticalmillingmachine.BasedontheX60Wnumericalcontrolmillingmachinetransformationdesignmainlyfromtheeconomy,convenience,practicality,reliabilitybasedonfourfactors,X60Wtypemillingmachinefornumericalcontrolmillingmachinemechanicalsystemdesign,hardwareandcircuitdesign.Aftertheimprovementofthemechanicaltransmissionpartofmachinetoolwithhighstatic,dynamicstiffness；kinematicpairbetweenthesmallfrictioncoefficient,notransmissiongap；thepowerislarge；easytooperateandrepair.普通X62W銑床的數(shù)控化改造設(shè)計(jì)IVX60WCNCmillingmachinemechanicalsystemdesignofservodrivesystemdesignandcalculation,thedesignandcalculationofballscrewpair.Feedtransmissionsystemdesign,longitudinal,transverse,demolitionofverticalfeedinggearbox,wherethehandwheelshaftthroughapairofgearandthelongitudinal,transverseandverticalstepmotor.NCsystemisbasedon8031single-chipdigitalcontrolsystem.Usingasmallervolumeofsinglechiptoachievethegenerallogicfunction,onthefeedsystemofthetwoaxescontrol.KEYWORDSNumericalcontroltransformation；positionprecision；steppingmotor；ballscrews；servodrivesystem普通X62W銑床的數(shù)控化改造設(shè)計(jì)目錄摘要.IIABSTRACT.III1機(jī)床數(shù)控化改造論證分析.11.1機(jī)床數(shù)控化改造的必要性.11.2我國(guó)數(shù)控系統(tǒng)發(fā)展現(xiàn)狀.22普通X62W銑床數(shù)控化改造分析.42.1主傳動(dòng)系統(tǒng)的改造設(shè)計(jì).42.1.1主軸部件選擇.52.1.2主軸組件的動(dòng)態(tài)特性.82.2進(jìn)給伺服系統(tǒng)的設(shè)計(jì).82.2.1對(duì)進(jìn)給伺服系統(tǒng)的基本要求.82.2.2進(jìn)給伺服系統(tǒng)的設(shè)計(jì)要求.92.2.3進(jìn)給伺服系統(tǒng)的動(dòng)態(tài)響應(yīng)特性及伺服性能分析.102.3X62W數(shù)控銑床改造設(shè)計(jì)方案及步驟.113普通X62W銑床數(shù)控化改造設(shè)計(jì)計(jì)算.113.1主軸系統(tǒng)計(jì)算
