工业机械手是六十年代发展起来的一门新技术。是近代自动控制领域中出现的一项新技术,并已成为现代机械制造生产系统中的一个重要组成部分。它是一种按一定程序,能自动搬运和操作的机械装置,并且能够代替人们的部分劳动,具有人的部分功能,而又没有人工操作的一些弱点。
工业机械手一般分为三类。第一类是不需要人工操作的通用机械手。第二类是需要人工操作的,称为操作机。第三类是专用机械手,主要附属于自动机床或自动线上,用以解决机床上下料和工件传送。这种机械手在国外称为“Mechanical Hand”,工作程序一般是固定的,因此是专用的。工业机械手也便属于此类,近几年来工业机械手发展很快。本次毕业设计就是在用于对缝纫机针的抛光,在抛光自动线上用摆动机械手,这一传送设备来代替人工的劳作。
工业机械手应用较多,发展较快。现在的机械手都具有了某种传感能力,触觉功能即是在机械手上安装反馈控制装置。更主要的是将机械手和柔性制造系统和柔性制造单元相结合,能根本上机械制造系统的人工操作状态。从经济方面看,工业机械手能够提高生产率,保证产品质量,降低废品率,提高基本装置的载荷能力;从技术方面看,操作机的使用与小批量生产中增长的产品质量及自动化生产有关。在大批生产中自动化程度最高,但在小批量生产中自动化程度次之。综上所述,有效地应用机械手, 是发展机械工业的必然趋势。

Abstract
The industry manipulator is a new technology developed in the sixties. It is a new technology appearing in modern automatic controlled field, and has already e an ponent in the production system of modern machine-building. It is one kind according to certain procedure , the mechanical device that can be carried and operated automatically, and the part that can replace people works, have some functions of people's, and there are not some manually operated weaknesses .
The industry manipulator is generally divided into three kinds. The first kind does not need the manually operated manipulator mon use . The second kind needs to be manually operated, is called the operating machine. The third kind is a special-purpose manipulator, affiliate on the automatic lathe or the transfer machine mainly, used to solve the upper and lower material of lathe and work piece to convey. This kind of manipulator is called " Mechanical Hand " abroad, the working routine is generally regular, so it is special-purpose. The industry manipulator belongs to this kind of too, the industry manipulator has been developed quickly in recent years. This graduation project is used in the polishing to the sewing machine needle , use the swing manipulator on the polishing transfer machine, this conveyance es to replace artificial work. In the mechanical manufacturing industry abr
