摘要数控车床今后将向中高挡发展，中档采用普及型数控刀架配套，高档采用动力型刀架，兼有液压刀架、伺服刀架、立式刀架等品种，预计近年来对数控刀架需求量将大大增加。但是数控回转工作台更有发展前途,它是一种可以实现圆周进给和分度运动的工作台，它常被使用于卧式的镗床和加工中心上，可提高加工效率，完成更多的工艺，它主要由原动力、齿轮传动、蜗杆传动、工作台等部分组成，并可进行间隙消除和蜗轮加紧，是一种很实用的加工工具。本课题主要介绍了它的原理和机械结构的设计，并对以上部分运用AUTOCAD做图,最后是对数控回转工作台提出的一点建议。关键词：数控回转工作台；齿轮传动；蜗杆传动；间隙消除；蜗轮加紧IAbstractNumericalcontrolthereisinthefuturelathetoinwilldevelop,themiddle-gradetoadoptpopularnumericalcontrolkniferestformacompleteset,adoptthemotiveforcetypekniferesttop-grandly,havesuchvarietiesaskniferestofhydraulicpressure,servokniferest,verticalkniferest,etc.concurrently,itisestimatedthatitwillincreasetonumericalcontrolkniferestdemandgreatlyinrecentyears.ThedevelopmenttrendoftheNumericalcontrolrotarytableis:Withthedevelopmentofnumericalcontrollathe,numericalcontrolkniferestbegintochangeonehundredsheets,electricliquidisiturgeandurgedirectiondevelopwhilebeingservotomakeupfast.Someoriginallydesignandisitcontinueelectricitytousetofourworkerlocationverticalelectronicmachineryofkniferestmainly-exposedtocontrolsystemcontrolsomedesigns.AnduseAUTOCADtopursuetotheabovepart,haveamoreocularknowledgeofelectronickniferest.ThelastpropositionhasputforwardthesuggestionandmeasuretoNumericalcontrolrotarytable.Keywords:Numericalcontrolrotarytable;Geardrive;Wormdrive;Gapeliminati-on;Thewormgearstepsup.II目录摘要...............................................................................................................IAbstract.......................................................................................................................II绪论...............................................................................................................1第1章数控技术发展趋势..........................................................................41.1性能发展方向......................................................................................41.2功能发展方向......................................................................................51.3体系结构的发展..................................................................................61.4智能化新一代PCNC数控系统.........................................................71.5本章小结..............................................................................................7第2章数控回转工作台的原理与及其组成......................82.1数控回转工作台工作的原理.............................................................82.2数控回转工作台主要的组成部分.....................................................92.3本章小结..............................................................................................11第3章数控回转工作台总体结构设计.....................................................123.1主要技术参数及其基本要求.............................................................123.1.1技术参数..........................................................................................123.1.2基本要求..........................................................................................123.2传动方案的确定.......................................................
