摘 要
本設(shè)計(jì)中機(jī)械手可模仿人的動(dòng)作功能，用以按固定程序抓取、搬運(yùn)物件或操作工具的自動(dòng)操作裝置。它可代替人的繁重勞動(dòng)以實(shí)現(xiàn)生產(chǎn)的機(jī)械化和自動(dòng)化，能在有害環(huán)境下操作以保護(hù)人身安全，因而廣泛應(yīng)用于機(jī)械制造、冶金、電子、輕工和原子能等部門。機(jī)械手主要由手部、運(yùn)動(dòng)機(jī)構(gòu)和控制系統(tǒng)三大部分組成。手部是用來(lái)抓持工件的部件，根據(jù)被抓持物件的形狀、尺寸、重量、材料和作業(yè)要求設(shè)計(jì)為夾持型。運(yùn)動(dòng)機(jī)構(gòu)，使手部完成各種轉(zhuǎn)動(dòng)、移動(dòng)或復(fù)合運(yùn)動(dòng)來(lái)實(shí)現(xiàn)規(guī)定的動(dòng)作，改變被抓持物件的位置和姿勢(shì)。運(yùn)動(dòng)機(jī)構(gòu)的升降、伸縮、旋轉(zhuǎn)等獨(dú)立運(yùn)動(dòng)方式，稱為機(jī)械手的自由度。為了抓取空間中任意位置和方位的物體，需有3個(gè)自由度。
關(guān)鍵詞：機(jī)械手，設(shè)計(jì)，手部，手腕，手臂，機(jī)身，結(jié)構(gòu)
Abstract
Robot arm to mimic certain actions of staff and functions, to capture a fixed procedure, carrying objects or operating tools, automation equipment. It can replace human labor in order to achieve the heavy mechanization and automation of production, can operate in hazardous environments to protect the personal safety, which is widely used in machine building, metallurgy, electronics, light industry and nuclear power sectors.Manipulator mainly by hand, sports bodies and the control system has three major components. Task of hand is holding the workpiece of the components, according to grasping objects by shape, size, weight, material and operational requirements of the various structural forms, such as clamp type, care support and the adsorption type, etc. . Sports organizations to accomplish a variety of hand rotation, move, or complex movement to achieve the required action to change the location of objects by grasping and posture. Sports organizations lifting, stretching and rotating the independence movement, is known as freedom manipulator. Crawl space to an arbitrary position and orientation of objects, the need for six degrees of freedom. Freedom is the mechanical design of the key parameters of hand. More freedom, greater flexibility of the manipulator, the more wide versatility。
Keywords: manipulator, design, hand, wrist, arm, body, structure
