设计简介
摘 要：在当今大规模制造业中，企业为提高生产效率，保障产品质量，普遍重视生产过程的自动化程度，机械手作为自动化生产线上的重要成员，逐渐被企业认同并采用。机械手的技术水平和应用程度在一定程度上反映了一个国家工业自动化的水平。目前，机械手主要承担着焊接、喷漆、搬运以及堆垛等重复性并且劳动强度极大的工作。机械手是卧式加工中心自动换刀装置中交换刀具的主要工具，它担负着把刀库上的刀具送到主轴上，再把主轴上已用过的刀具返回刀库上的任务。

Abstract:To improve the efficiency of production and ensure quality of production, the enterprises generally attach importance to the automation of production process in today’s mass manufacturing. As an important member of automation production line, manipulator gradually recognized by enterprises. Technology level and application level of the manipulator in a certain extent reflects the level of industrial automation in a country. At present, the manipulator is mainly used for welding spray painting, handling, stacking repetitive work and labor intensity greatly. Manipulator is automatically change tool device the main tool to exchange tool, it bears on the knife library on the tool to spindle, and then the spindle has used tool returns tasks on tool store.
