It also introduces the development of the manipulator inour country and foreign country. T his paper designs the manipulator ’s whole precept, according to the design requirements, forming the manipulator ’s cylindrical coordinate and four degrees of freedom, and its technical parameters as the arm telescopic stroke is 500mm,the arm lifting stroke is 100mm, at the same time, the manipulator hand structure is determined for clamp type, the manipulator ’s wrist, arm, and base structure, drawing the manipulator hydraulic system diagram. R esearching hydraulic system diagram, improve the quality and efficiency of drawing. Control manipulator by PLC position control, select a suitable PLC type , According to the design requirements , using FX2N-48M according tothe manipulator working flow diagram, setting PLC control precept, assign I/O connect port, drawing the exterior connect diagram of PLC. Key words: manipulator, hydraulic, PLC control 充值下载即送 CAD 图纸, QQ 36396305 目录 1 绪论............................................................................................................................................................ 1 选题背景及意义.............................................................................................................................. 1 国内外研究现状和趋势...........................................................................
