[摘要]数控机床的发展与应用，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。
本文对JCS-013数控钻铣床的换刀机械手的各个组成部分、工作原理、坐标形式、驱动方式等进行了讨论。对一些主要零部件进行了分析计算。
换刀机械手应当满足换刀时间短、运行平稳可靠、定位精确、体积小以及控制方便灵活等要求。带刀库的数控机床的关键在于机械手与主轴的自动换刀。本课题就是针对JCS-013数控镗铣床换刀机械手，在分析其组成部分、工作原理的基础上使用现代机械设计理论进行改进，把原来纯液压驱动改为电液混合驱动。提高了效率。对手抓的活动手指使用CATIA软件的有限元分析模块分析出在静力作用下的应力情况和变形情况。得出了相应的分析报告。

The abstract] the numerical control engine bed development and the application, greatly reduced the components processing non-cutting time, enhanced the production efficiency.Along with the numerical control engine bed popularization application, the machine-finishing automaticity enhances greatly, the numerical control engine bed develops has now been common the application one kind of renewal, the more advanced manufacture equipment.The processing center has the knife storehouse and trades the knife installment automatically, may realize according to the pre-set sequence carries on the multi-working procedure processing to the work piece.
This article drilled the milling machine to the JCS-013 numerical control to trade the knife manipulator's each constituent, the principle of work, the coordinates form, the drive type and so on has carried on the discussion.Has carried on the analysis computation to some main spare parts.
Trades the knife manipulator to have to t
