毕业设计说明书（论文）中文摘要本设计是一带自动上下料装置的高精度精密钻床。钻床是机械行业中最普通的一种机床，然而，此次设计特点是：高精度，同时，为了克服以往人工上下料的诸多缺点，设计采用自动上下料，这就增加了设计的难度。自动上下料装置是自动机床和自动线设计中复杂程度高而且难度较大的组成部分之一。自动上下料装置所完成的工作是将散乱无序的工作零件经过定向机构的定向排列，然后顺次把它们排在机床夹具上，并在加工完后从夹具上卸下成型工件。本设计的微型精密钻床，因采用了自动上下料装置，使成批生产中效率显著，同时降低了生产成本，他所加工的对象是微小零件如医疗手术针的钻削加工，针对工件的特点，涉及采用了相应设备和装置如气压上料，由于工件较小(0.3～4mm),所以加工精度提到设计要求中，钻削微小的偏差都能导致工件的报废，因此它也是此次设计的关键部分。此次设计中我采用了气压上料，弹性卡紧，推杆下料和精度差动微调等手段。关键词高精度微型自动上下料毕业设计说明书（论文）外文摘要Title:AHighAccuracyThatTakesVoluntarilyAboutMaterialInstallationPreciseDrillingMachineAbstract:Itisahighaccuracythattakesvoluntarilyaboutmaterialinstallationprecisedrillingmachine.Drillingmachineisakindofmostordinarymachinetoolinmechanicalprofession,however,thisdesigncharacteristicis:Highaccuracyatthesametimeadoptsvoluntarilyaboutmaterialforsurmountingmanyshortcomingofformerartificialaboutmaterialanddesigning,thishasincreasedthedifficultyofdesign.Onautomatic,nextmaterialinstallationisoneofcomplexcompositionpartswithhighlevelandgreaterdifficultyinthebedofautomaticmachineandthedesignoftransfermatic.Onautomatictakingoffmaterialinstallationtheworkcompletedpassesscatteredindisorderoutoforderworkingelementdirectionalorganizationisdirectionaltoputthemontheclampingapparatusofmachinetoolinorderinorder,then,queueup,andunloadtypework-piecefromclampingapparatusafterprocessingisover.Theminiprecisedrillingmachineofthisdesignmakestheefficiencyinbatchproductionnotablebecauseofhavingadoptedvoluntarilyaboutmaterialinstallation,hasatthesametimereducedproductioncost,theobjectthatheprocessesissmallelementasmedicaloperationneedlegetintotocutprocessing,accordingtothecharacteristicofwork-piece,havebeenconcernedwithtoadoptcorrespondingequipmentandinstallationexpectsonatmosphericpressure,sincework-pieceisless(0.3～4mm),so,processingprecisiontomentiongotodesignrequirement,getintotocutsmalldeviationcancausework-piecescrap,thereforeitisalsothecrucialpartofthisdesign.Inthisdesign,Ihaveadoptedatmosphericpressureonmaterial,flexiblecardisexpectedtightly,under
