1、摘要这次毕业设计我选的题目是机械手夹持器设计,本课题是针对流水线自动化生产而设计的机械夹持器。本课题包括机械夹持器总体设计、计算;液压传动系统的设计与计算、部件和零件设计。机械手与机器人的联系非常密切,机械手的应用和发展,大大促进了智能机器人的研制。同时,机械手是一门应用很广的学科,它几乎在各个部门和学科都有应用,尤其在机械工业和铁路工业中。我所设计的夹持器基本要求如下:(1)应具有适当的夹紧力和驱动力;(2)手指应具有一定的开闭范围;(3)应保证工件在手指内的夹持精度;(4)要求结构紧凑,重量轻,效率高;(5)应考虑通用性和特殊要求。设计参数及要求如下:(1
2、)采用手指式夹持器,执行动作为抓紧—放松;(2)所要抓紧的工件直径为80mm 放松时的两抓的最大距离为110120mm/s,1s抓紧,夹持速度20mm/s;(3)工件的材质为5kg,材质为45#钢;(4)夹持器有足够的夹持力;(5)夹持器靠法兰联接在手臂上。由液压缸提供动力关键词:机械手,夹持器,手指,液压缸。abstractInthe graduationdesign,The topic Ichoose ismanipulatorgrippersdesign,thistopic isdesigned forautomatic productionline o
