加工中心刀库自动换刀装置摘要切削加工正在进入以高速切削为特征的发展阶段,因高速切削而切削效率飞速提高，进一步减少机床加工辅助时间的技术也伴随高速切削的发展而不断发展。快速换刀技术是减少加工辅助时间重要手段。刀库和交换主轴换刀装置是转塔头换刀装置和刀库式换刀装置的结合。首先把加工过程中需要使用的全部刀具分别安装在标准刀柄上，在刀库中进行选刀，并由刀具交换装置从刀库中取出刀具，把刀具安装在非工作主轴上。换刀时间通过转塔头交换装置旋转180°，交换主轴。这样就可以使切削加工和主轴换刀同时进行，由此可知换刀时间实际就是已经装好刀具的两个主轴的换位时间，使辅助时间减少到最少，即机床切屑对切屑时间达到最短。同时，刀库可以存放数量很大的刀具，因而能够进行复杂的多工序加工，这样就明显提高了机床的适应性和加工效率。关键词高速切削；刀库；交换主轴；换刀装置；换刀时间DesignOfAutomaticToolChangeOnToolMagazineAbstractCuttingisdevelopingwhichhasthecharacteristicofhigh-speedcutting.Thehigh-speedcuttinghasleadtherapidimprovementofefficiencyofcutting,thenthetechnologywhichwillfurtherreducemachiningassistanttimeisdevelopingasthehigh-speedcutting.ATC（Toolchanger）technologyisoneofthemostimportantmethodstoreducetheassistanttimeincutting.ThetoolmagazineandexchangespindlearetheintegrationofturretheadandATC.First,allthecutting-toolwhichisneededareinstalledonthestandardcutting-toolhandle,andthenselectatoolintoolmagazine,andtakethetoolbyexchangedeviceintoolmagazine,installitontothenone-workspindle.Duringtoolchanging,turretheadisrotated180°tochangethemainspindle.Thatwillenablecuttingandexchangingtoolofspindlesimultaneous,itmeansthetimeofcutting-toolplaces.Thusassistanttimeisleast.Meanwhilethetoolmagazinecanholdalargenumberofcuttingtool,somorecomplexmachiningprocessescanbedone,theadaptabilityandprocessingefficiencyofmachinecanbeimproved.KeywordsHigh-speedCutting；ToolMagazine；ExchangeSpindle；ATC；Tool-chasingTime目录摘要.......................................................................................................................IAbstract................................................................................................................II1.1背景及研究意义........................................................................................31.2自动换刀装置国内外发展与现状............................................................31.3工作内容....................................................................................................41.4设计构想....................................................................................................5第2章设计总体方案论证..................................................................................62.1刀库和交换主轴换刀装置的原理............................................................72.1.1主轴交换的原理.................................................................................72.1.2主轴抬起及转位的原理.....................................................................72.1.3刀库及换刀装置.................................................................................82.2本章小结....................................................................................................9第3章主轴转动的设计计算............................................................................103.1传动系统的原理设计..............................................................................103.1.1电动机的选择...............................
