摘要:机械手是在机械化、自动化过程中发展起来的一种新型装置。它能模仿人手部分动作,按照预先设定的程序,轨迹或其他要求,实现抓取,搬运工件或操纵工具的机械化装置。在现代生产中,机械手被广泛应用于自动生产线,机器人的研究和生产已经成为高科技领域内,迅速发展起来的一门新兴的技术,它促进了机械手的发展,使得机械手能更好的与机械化、自动化有机结合。
本文的移置机械手的设计,采取直角坐标式运动形式的机械手,液压驱动的方式,通过液压缸,阀,油泵,油箱等实现运动。同时采用PLC控制电磁换向阀,控制油缸的进油,从而控制机械手的直线移置运动,进而实现其自动化,具有提高生产效率,实现实时控制的意义。

Abstract: Manipulator is one kind of new model device automating to develop in process in can imitate humen’s hand action. According to the predetermined programme, track and other requirements. Realize grabing carrying workpieces and operating tools by a Mechanization device. In the production of now, manipulators are widely used in automatic production line. Robot in the research and production has e a new developing rapidly technology in a high-tech area. It has promoted the development of manipulator .Especially,making manipulator can better implementation and mechanization, anic integration.
The writing of moving manipulator design,Adopt dyadic motion of right angle coordinate form manipulator, way that hydraulic pressure drives, by the hydraulic cylinder , valve , oil pump,the fuel tank and so on to realizing motion. at the same time ,Adopt PLC to control ism changing-over valve. controlling oil moving forward to oil jar, So as to control of the manipulator linear movement of sports, and achieve its automation, With increasing production efficiency, realizing the significance of the real-time control.
Key words: Manipulator;PLC;Hydraulic cylinder;ism changing-over valve
