1、本科生毕业设计题 目:五自由度机械手结构设计院 (系): 机械工程学院 班 级: 机电08-3 姓 名: 田国玉 学 号: 5 指导教师: 陈焕林 教师职称: 讲师 摘 要本课题设计的多功能机械手为通用机械手,主要由手爪、手腕、手臂、腰部、机座等组成。本机械手机身采用机座式,自动线围绕机座布置。具有腰部旋转、大臂仰俯、中臂仰俯、小臂仰俯和腕部旋转5个自由度。本次设计的机械手能对不同物体完成多种动作。工业机械手可以代替人手的繁重劳动,显著减轻工人的劳动强度,提高劳动生产率和自动化水平。工业生产中经常出现的笨重工件的搬运和长期频繁,单调的操作。如果没有机械手,那么工人的劳动强度是很高的,有时候还要
2、用行车员工件,生产速度大大延缓,这种情况采用机械手是很有效的。此外,它能在高温、低温、深水、宇宙、反射性和其他有毒、有污染环境条件上进行操作。更显其优越性,有着广阔的发展前途。关键词:机械手;关节型;五自由度AbstractThe design of multifunctional mechanical hand for universal mechanical hand, mainly by the gripper, wrist, arm, fuselage, and base composition, with feeding, reversal and transposition of
