随着数控机床的普及应用,机械加工的自动化程度大大提高,数控机床发展成了当今普遍应用的一种更新、更先进的制造设备。
加工中心带有刀库和自动换刀装置,可以实现按照预定程序对工件进行多工序加工。
数控卧式镗铣床是一种具有自动换刀装置和任意分度数控转台的数字控制机床,工件在一次装夹后能自动完成几个侧面的的多种工序的加工。
数控卧式镗铣床刀库机械手升降机构由液动机、滚珠丝杠副、减速齿轮、摩擦片式电磁离合器等构成。
了解刀库机械手升降机构的性能要求了解刀库机械手升降机构的工作原理,进行结构设计和计算分析液动机带动滚珠丝杠转动,带动手架运动,通过减速和离合器吸合,丝杠制动,使手架准确停在换刀位置,良好的结构设计能够实现刀库中刀具的快速更换,提高机床的加工效率。
