平衡臂机械手的设计
摘要
随着工业自动化发展的需要,机械手在工业应用中越来越广泛。该设计以2自由度平衡臂机械手为研究对象,能实现对物体的自动抓龋设计根据用途分析了机械手的动作循环及工作原理,设计了机械手的液压系统和机构,主要侧重结构细节的设计,对机械手进行了总体方案设计,确定了机械手的爪式手部结构,设计了机械手的手臂结构,计算出了手臂的部件尺寸。对主轴的尺寸和强度进行了校核等。确定了机械手的液压系统和采用PLC控制系统,绘制出机械手液压系统工作原理图,绘制了装配图和零件图。
液压机械手主要是以液体为介质,并且利用液体的压力由此来驱动执行机构的运动。其主要特点是:首先,能够实现循环工作的自动化和自动过载保护;其次,控制调节简单,方便省力;最后,这样能够更好地实现无间隙传动,还可以让操作更加平稳。
机械手是在机械自动化生产中逐步发展出的一种新型装置。现代生产过程中机械手被广泛的应用到自动生产线中。机械手目前虽然不如人手的灵活多变,但它具有重复性,无疲劳,不惧危险,有大的抓举力量,因此越来越多的被广泛运用。机械手技术涉及机械学、力学、自动控制技术、传感技术、电气液压技术,计算机可编程技术等,是一门跨学科综合技术。
