搬运机械手设计 摘 要 机械手是一种能自动控制并可从新编程以变动的多功能机器，他有多个自由度，可以搬运物体以完成在不同环境中的工作。机械手能模仿人手和臂的某些动作功能，用于按固定程序抓取、搬运物体或操作工具的自动操作装置。它可以代替人的繁重劳动以实现生产自动化和机械化，能在有害环境下操作以保证人的安全，因而广泛应用于机械制造、冶金、电子、轻工和原子能等部门。在工业部门中应用的机械手称为工业机械手。 工业机械手是近代自动控制领域中出现的一项新技术，是近几十年发展起来的一种高科技自动生产设备。涉及到力学、机械学、电器液压技术、自动控制技术、传感器技术和计算机技术等科学领域，是一门跨学科综合技术。它的特点是可以通过编程来完成各种预期的作业，在构造和性能上兼有人和机器各自的优点，尤其体现在人的智能和适应性。机械手作业的准确性和环境中完成作业的能力，在国民经济领域有着广泛的发展空间。 设计包含了机械手的结构设计及控制电路设计，其中在结构设计这方面包含了机械手的手部结构、腕部结构、臂部结构设计及机身的整体结构设计。在控制电路设计这方面包含了液压驱动控制设计、器件的选择设计、PLC可编程自动控制电路设计。本毕业设计《搬运机械手机构与控制电路设计》非常适合作为机械电子工程这门专业大学四年的一个总结。因为其中包含了机械设计与电路设计，是机械与电子的结合体，能充分体现这门专业的内涵。 关键词：机械手；手部；腕部；臂部；机身；液压；电路 Design of Manipulator Mechanism and Control Circuit ABSTRACT Manipulator is a kind of automatic control and from the new process to change the multi-function machine, he has multiple degrees of freedom, can carry objects to complete the work in different environments. Mechanical hand can imitate hand and arm function for some action, according to a fixed program to crawl, moving objects or to operate the automatic tool operation device. It can replace people arduous labor to realize production automation and mechanization, can operate under the hostile environment to guarantee the security of the person, and so it is widely used in machinery manufacturing, metallurgy, electron, light industry and atomic energy industries. In the industrial sector in the application of the mechanical hand is called the industrial manipulator. Industrial machinery hand is the modern automatic control in the field of a new technology developed in recent years, is a high-tech automated production equipment. Involves mechanics, mechanical, electrical and hydraulic technology, the automatic control technology, sensor technology and computer technology and other fields of science, is an interdisciplinary comprehensive technology. It is characterized by a variety of programming to complete the expected operation, in the structure and performance of both people and machines to thei
