1、同时人的劳动强度非常大，有时还会出现失误及伤害。显然，这严重影响制约了整个生产过程的效率和自动化程度。机械手的应用很好的解决了这一情况，它不存在重复的偶然失误，也能有效的避免了人身事故。机器人并不是在简单意义上代替人工的劳动，而是综合了人的特长和机器特长的一种拟人的机械装置，既有人对环境状态的快速反应和分析判断能力，又有机器可长时间持续工作、精确度高、抗恶劣环境的能力，从某种意义上说它也是机器的进化过程产物，它是工业以及非产业界的重要生产和服务性设备，也是先进制造技术领域不可缺少的自动化设备。液压驱动是机械手中使用最为广泛的一中驱动方式。该灯壳冲压生产线用伺服型下料机械手的驱动方式也选用了液压

2、驱动。因此，本次毕业设计的主要任务是为灯壳冲压自动生产线用伺服型下料机械手配备驱动系统。其中包括液压系统原理的设计，液压泵站的设计。此外，参照机械手设计基础还画出了机械手的外部结构图，升降油缸和回转油缸的装配图、手指和手腕的装配图。 本文主要叙述了液压方面的一些设计计算过程。其中包括：液压缸的参数设计，各种液压元件的选择，电机的选择，液压集成块的设计，液压系统的安装和维护。关键字 机械手；液压驱动；液压泵站；液压系统Lamp Shell Stamping Cutting Manipulator Hydraulic System DesignAbstractMachinery industry
