1、本科毕业设计(论文)题目：数控卧式镗铣床刀库机械手升降机构设计与分析系别：机电信息系专业：机械设计制造及其自动化班级：学生：学号：指导教师：2013年05月数控卧式镗铣床刀库机械手升降机构设计与分析摘要数控卧式机床的发展与应用，大大降低了零件的加工辅助时间，提高了生产效率。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
2、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。关键词:升降机构；JCS-013数控镗铣床；液动机；滚珠丝杠；手架；离合器；VCNChorizo
