基于PLC的液压驱动式机械手动作设计

摘要

A kind of hydraulic manipulator was introduced. The traits includled simple configuration and balanced movement. It was fit for conveying heavy objects. By analyzing the movement process, the hydraulic loop was designed, simulation and movement control based on PLC were completed. A simulated expriment was done on YZ-02 fluid driving platform. The results show that the hydraulic manipulator has strong power and stable performamce. The used differential loop improve local velocity.%介绍一款采用液压驱动式的机械手,该机械手的特点是结构简单、输出力大、动作平稳,适合于大物件的搬运工作.针对该机械手各动作情况分别对其进行液压回路设计、模拟仿真、PIE顺序控制,并在YZ-02型智能化液压传动实验台上进行机电液一体化模拟实验.实验结果表明:液压驱动式机械手抓力较大,工作性能稳定,通过差动回路可改善其局部运行速度.
