摘要本論文主要說明組合機(jī)床設(shè)計(jì)的基本過程及要求。組合機(jī)床是按高度集中原則設(shè)計(jì)的，即在一臺機(jī)床上可以同時完成同一種工序或多種不同工序的加工。組合機(jī)床發(fā)展于工業(yè)生產(chǎn)末期，與傳統(tǒng)的機(jī)床相比：組合機(jī)床具有許多優(yōu)點(diǎn)：效率高、精度高、成本低。它由床身、立柱、工作臺、及電源一些基本部件及一些特殊部件，根據(jù)不同的工件加工所需而設(shè)計(jì)的。在組合機(jī)床上可以完成很多工序，但就目前使用的大多數(shù)組合機(jī)床來說，則主要用于平面加工和孔加工兩大類工序。本論文則說明鉆孔組合機(jī)床的設(shè)計(jì)，用來完成鉆6個孔的工序。主要內(nèi)容包括三大部分：（1）、制定工藝方案通過了解被加工零件的加工特點(diǎn)、精度和技術(shù)要求、定位夾緊情況、生產(chǎn)效率及機(jī)床的結(jié)構(gòu)特點(diǎn)等，確定在組合機(jī)床上完成的工藝內(nèi)容及加工方法，并繪制被加工零件工序圖。（2）、組合機(jī)床的總體設(shè)計(jì)確定機(jī)床各部件之間的相互關(guān)系，選擇通用部件和刀具的導(dǎo)向，計(jì)算切削用量及機(jī)床生產(chǎn)效率、繪制機(jī)床的尺寸聯(lián)系圖及加工示意圖。（3）、組合機(jī)床部件設(shè)計(jì)包括專用主軸箱的設(shè)計(jì)，傳動布局合理，軸與齒輪之間不發(fā)生干涉，保證傳動的平穩(wěn)性和精確性。專用主軸設(shè)計(jì)、軸承的選用及電機(jī)的選擇等。另外，本文還涉及到大量的設(shè)計(jì)和計(jì)算，包括：（1）、主軸的選擇和傳動布置，以保證加工過程中被加工零件的精度；（2）、傳動軸的設(shè)計(jì)和校核，以保證軸的剛度；（3）、齒輪的設(shè)計(jì)、計(jì)算，對齒輪的強(qiáng)度和剛度進(jìn)行校核；關(guān)鍵字：組合機(jī)床；設(shè)計(jì)；過程；功能AbstractThisthesismainlyelucidatesthebasicprocessandrequirementsthatdesignofthecombinationmachine.Combinationmachineisdesignedaccordingthefundamental,whichhighlycentralized,or,morecorrectlyitcanprocessoneworkingprocedureormoredifferentworkingproceduresatonetime.Combinationmachinewasdevelopedintheendofindustrialproductioncomparedwithtraditionalmachine；combinationmachinehasmanyadvantages,suchashighefficiency,highaccuracyandlowcost.Itiscomposedofsomegeneralparts,suchasbed,column,workable,powerunit,andsomespecialpartsdesignedaccordingtodifferentworkpiecemachiningneed.Theprefaceofalotofworkscanbecompletedonthecombinationmachine,butinregardtothemajoritycurrentusageofcombinationmachine,thenandprimarilyusedfortheflatsurfacetoprocessandtheboretoprocesstwobigworkpreface.Thisthesisexpoundsalltheprocessesofthethrottlevaluestappetsholeoftheaircylinderboringthecombinationdrillthatdesignsofmachine.Themainpartincluding:(1)FormulatingtechnologicalplanWe,velearnedthecharacteristicofthepartdesigned,accuracyandspecification,locatingandfixing,productivityandmachiningstructurebythepractice.Thenthetechnologicaloperationandworkordercanbedeterminedwhichcanbefinishedincombinationmachine.(2)Combinationmachineframedesigndeterminestheinterrelationofthedifferentpartinthemachiningtool,selectgeneralpartsandtooloriented.Thencomputecutfeedandproductivityfinallydrawasketchmapofthemachine.(3)Combinationmachinepartsdesignincludingheadstock、propertransmissionlayout、shaftandgearmovefreelywithoutinterferencewhichensurethestabilityandaccuracyduringtransmission,thendesigndedicatedselectbearingsandengineetc.Hydraulicpressureequipmentdesignslipwayandlocatingandfixingdeviceareallcontrolledbyhydraulicpressure.Itadoptsmanyhydrauliccontrolvalves,whichensurethestability,circulationandaccuracy.Inaddition,thethesisdealswithamountofcomponentsdevicesandcalculations,including:(1)Choiceofthemainshaftanddisposaloftransmission,bydoingsotoensuretheaccuracyofcomponentsmachininginprocesswhenthemainshaftrotating；(2)Thedeviceandcheckofthetransmissionshaft,soitcanassuretherigidityoftheshaftisallowable；(3)Geardeviceandcalculations,checktheperformanceinthestrengthandrigidityofit；DesignofthehydraulicpressuresystemHydraulicsystemisaveryimportantpartinthisthesis,thedesignofitherenotonlyensurestherationality、equipoiseandstabilityofthemotionoftheslipway,butalsosatisfiestherequirementsofdifferentworkenvironment.Somanydesignandcalculationsaboutitinthisthesissuggeststhissystemfullymeetstherequirementsindesignandworktheoretically.Keywords:combinationmachine；design；process；function目錄摘要.iAbstract.ii1緒論.11.1、組合機(jī)床及其特點(diǎn).11.2、組合機(jī)床的分類.212.1、具有固定式夾具的單工位組合機(jī)床.21.2.2、具有移動式夾具的（多工位）組合機(jī)床.21.23、轉(zhuǎn)塔主軸箱式組合機(jī)床.31.3、組合機(jī)床的工藝范圍.31.4、組合機(jī)床的發(fā)展方向.32組合機(jī)床總體設(shè)計(jì).62.1、組合機(jī)床工藝方案的制定.62.1.1、加工工序和加工精度.62.1.2、被加工零件特點(diǎn).62.1.3、工件生產(chǎn)方式.62.1.4、工藝基面的分析.72.1.5、加工工藝的分析.72.1.6、切削用量的選擇.72.2、組合機(jī)床切削用量的選擇.82.3、組合機(jī)床配置型式的選擇.82.4、組合機(jī)床的總體方案設(shè)計(jì).82.4.1、被加工零件工序圖.92.4.2、加工示意圖.92.4.3、組合機(jī)床生產(chǎn)率的計(jì)算.132.4
