1、摘 要到了越来越快的发展,其智能化程度越来越高,已经应用于工业生产制造、医疗和军事等各个领域,成为当前生产和高科技研究中的一个极其重要的构成部分。机器人上最为关键的执行部件就是机械臂,因此深入的研究机械臂有着非凡的现实意义。由于机械臂所对应的自由度不止一个,可用于在工业生产中完成各种工作。其能够替代人类从事各种重复、单调、繁重以及具备一定危险系数的作业,减轻工人的工作强度,提升工作效率和自动化水平。 本设计采用圆柱形坐标形式,机械手的旋转运动采用步进电机驱动,双作用气缸的运动增添辅助导向装置,增添了腰部所对应的导向性能以及刚性强度,腕部采用旋转型式的气缸以实现180旋转运动。一端增加平衡装置使
2、整体运动平稳。末端执行器的驱动型式采用形状记忆合金,其具备相对较轻的质量、相对较小的占地体积、单位质量具备较大的恢复力,且整体结构相对较为简单、控制方便易操作,无污染。论文按照手爪、手臂、腕部,底座进行设计。涉及气动技术、理论力学、机械原理以及相关零件的机械设计等。机械手能实现整体旋转,腰部、臂部伸缩,腕部旋转及摆动五个自由度,在导师的耐心详尽的指导下,通过查阅文献,书籍,经过努力最终完成。 关键词:装配机械手;工业领域;气缸 Abstract With the rapid development of computer technology and automatic control tec
