摘要
工业机械手是现代机械化的一种新型生产方式,同时也是智能自动化研发出来的新型设备。现今随着科学技术的迅猛发展,机械手的原理及应用技术越来越受到重视,在当代工业工厂的生产制造中,工业机器人已经全面应用于车间的自动化流水线,因而,人们开始日趋迫切的对机器人进行研究改造。其中,液压机械手用途最为广泛,所以本次对机械手的液压系统进行设计。
在液压驱动机构中,所述机械手的手臂伸缩和升降均采用了双作用活塞液压缸并由导向杆导向,以确保机械手的运动精度,手腕的旋转采用摆动式液压缸(回转油缸),机械手的手臂旋转和手爪夹持被采用齿条活塞式液压缸。
本课题通过对机械手和液压传动原理的应用技术设计,对工业机械手的液压系统的分类,结构,特性,受力等方面进行分析,并分析液压系统的工作原理。具有液压系统结构的机械手机器人可以在空间中灵活抓取移动物体,并且操作自由度很高,可以在高温和危险的位置作业,从而减少人力,并大大促进生产节奏。
