高速铁路轴承滚子半自动车床的改造 Abstract: Withthedevelopmentofhigh-speedrailways,thebearingsusedinhigh-speedtrainsarerequiredtohavehighprecisionandstability,andtheprocessingtechnologyofbearingshasalsobeengreatlyimproved.Thispaperintroducesthetransformationofasemi-automaticlatheforprocessinghigh-speedrailwaybearingrollers,includingthehardwaretransformationofthelatheandthesoftwareprogrammingofthelathecontrolsystem.Thetransformationimprovestheprocessingprecisionofthebearingrollersandreducesthelaborintensityoftheworkers. Introduction: High-speedrailwayisamodernmeansoftransportationthathasdevelopedrapidlyinrecentyears.Ithastheadvantagesofhighspeed,safety,comfort,andconvenience.Asthekeycomponentofthehigh-speedrailway,thebearingisanimportantfactoraffectingtherunningstabilityandsafetyofthetrain.Therefore,thequalityrequirementsforhigh-speedrailwaybearingsareextremelystrict,andtheprocessingtechnologyforhigh-speedrailwaybearingshasalsobeengreatlyimproved.Asahigh-precisionprocessingequipment,thesemi-automaticlathehasbeenwidelyusedintheprocessingofhigh-speedrailwaybearings.However,thetraditionalsemi-automaticlathehascertainlimitationsintermsofprocessingprecisionandefficiency.Inordertomeettherequirementsofhigh-speedrailwaybearingprocessing,itisnecessarytocarryoutatransformationofthesemi-automaticlathe. 1.Hardwaretransformationofthesemi-automaticlathe Thehardwaretransformationofthesemi-automaticlathemainlyincludesfouraspects:spindlemodification,feedsystemmodification,toolholdermodification,andcoolingsystemimprovement. 1.1Spindlemodification Inordertoimprovetheprocessingprecisionofthebearingrollers,ahigh-precisionspindleisrequired.Theoriginalspindleofthesemi-automaticlatheisreplacedwithahigh-precisionspindle,whichcaneffectivelyimprovetheprocessingstabilityandprecisionofthebearingrollers. 1.2Feedsystemmodification Thefeedsystemofthesemi-automaticlatheismodifiedtoaservofeedsystem.Thetraditionalfeedsystemisdrivenbyamotordirectlyconnectedtotheleadscrew,whichispronetovibrationandnoiseduringoperationan
