【正文】 因此，進(jìn)行機(jī)械手的研究設(shè)計是非常有意義的。吧機(jī)床設(shè)備和機(jī)械手共同構(gòu)成一個柔性加工系統(tǒng)或柔性制造單元，它適用于中、小批量生產(chǎn)，可以節(jié)省龐大的工件輸送裝置，結(jié)構(gòu)緊湊，而且適應(yīng)性很強(qiáng)。近年來，隨著電子技術(shù)特別是電子計算機(jī)的廣泛應(yīng)用，機(jī)器人的研制和生產(chǎn)已成為高技術(shù)領(lǐng)域內(nèi)迅速發(fā)展起來的一門新興技術(shù)，它更加促進(jìn)了機(jī)械手的發(fā)展，使得經(jīng)銷商能更好地實(shí)現(xiàn)與機(jī)械化和自動化的有機(jī)結(jié)合。 機(jī)械手主要由手部和運(yùn)動機(jī)構(gòu)組成。 能模仿人手和臂的某些動作功能，用以按固定程序抓取、搬運(yùn)物件或操作工具的自動操作裝置。手部機(jī)構(gòu)隨使用場合和操作對象而不同，常見的有加持、托持和吸附等類型。應(yīng)用機(jī)械手可以代替人從事單調(diào)、重復(fù)或繁重的體力勞動，實(shí)現(xiàn)生產(chǎn)的機(jī)械化和自動化，代替人在有害的環(huán)境下的手工操作，改善勞動條件，保證人身安全。 軍事工程及生物醫(yī)學(xué)方面的研究和實(shí)驗(yàn)。 在裝配作業(yè)中應(yīng)用廣泛，在電子行業(yè)中它可以用來裝配印制電路板，在機(jī)械行業(yè)中它可以用來組裝零部件。 （ 3）導(dǎo)軌式搬運(yùn)系統(tǒng)（懸掛軌道、輕型軌道、單梁起重機(jī)、雙梁起重機(jī)）。工業(yè)中采用的鍛造操作機(jī)也屬于這一范疇。它可以根據(jù)任務(wù)的需要編制程序，以完成各項規(guī)定的操作。 機(jī)械手控制系統(tǒng)的主要作用是控制機(jī)械手按一定的程序、方向、位置、速度進(jìn)行動作，簡單的機(jī)械手一般不設(shè)置專用的控制系統(tǒng)，只采用行程開關(guān)、繼電器、控制閥濟(jì)南大學(xué)畢業(yè)設(shè)計外文資料翻譯 8 及電路便可以實(shí)現(xiàn)傳動系統(tǒng)的控制，使執(zhí)行機(jī)構(gòu)按要求進(jìn)行動作。簡單的機(jī)械手可以沒有手腕。 2機(jī)械手的組成 機(jī)械手的形式是多種多樣的，有的較為簡單，有的較為復(fù)雜，但基本的組成形式是 相同的，一般由執(zhí)行機(jī)構(gòu)、傳動系統(tǒng)、控制系統(tǒng)和輔助裝置組成。 ，它的動作和反應(yīng)都快，這是氣動突出的優(yōu)點(diǎn)之一。 為什么選擇設(shè)計機(jī)械手用氣動來提供動力：氣動機(jī)械手是指以壓縮空氣為動力源驅(qū)動的機(jī)械手。 在現(xiàn)實(shí)生活中，你是否會發(fā)現(xiàn)這樣一個問題：在機(jī)械工廠里，加工零件裝料的時候是不是很麻煩的，勞動生產(chǎn)率不高，生產(chǎn)成本大，有時候還會發(fā)生一些人為事故，導(dǎo)致加工者受傷。那些電子和汽車業(yè)的歐美跨國公司很早就在它們設(shè)在中國的工廠中引進(jìn)了自動化生產(chǎn)?？删幊坛绦蚩刂破?PLC 控制的上下料機(jī)械手控制系統(tǒng)動作簡便、線路設(shè)計合理、具有較強(qiáng)的抗干擾能力，保證了系統(tǒng)運(yùn)行的可靠性，降低了維修率，提高了工作效率。它的特點(diǎn)是可通過變成來完成各種預(yù)期的作業(yè)任務(wù)，在構(gòu)造和性能上兼有人和機(jī)器各自的優(yōu)點(diǎn)，尤其體現(xiàn)了人的智能和適應(yīng)性。 particularly in the hightemperature, high pressure, low temperature, low pressure, dust, explosive, toxic and radioactive gases such as poor environment can replace the normal working people. Here I would like to think of designing a machine hand to be used in actual production. Why would a machine hand designed to provide a pneumatic power: pneumatic machine hand refers to the pressed air as power sourcedriven machine hand. With pressuredriven and other energydriven parison have the following advantages: 1. Air inexhaustible, used later discharged into the atmosphere, does not require recycling and disposal, do not pollute the environment. (Concept of environmental protection) 2. Air stick is small, the pipeline pressure loss is small (typically less than asphalt gas path pressure drop of onethousandth), to facilitate longdistance transport. 3. Compressed air of the working pressure is low (usually 4 to 8 kg/per square centimeter), and therefore moving the material ponents and manufacturing accuracy requirements can be lowered. 4. With the hydraulic transmission, pared to its faster action and reaction, which is one of the advantages pneumatic outstanding. 5. The air cleaner media, it will not degenerate, not easy to plug the pipeline. But there are also places where it flies in the ointment: 1. As the pressibility of air, resulting in poor aerodynamic stability of the work, resulting in the implementing agencies as the precision of the velocity and not easily controlled. 2. As the use of low atmospheric pressure, the output power cannot be too large。 畢業(yè)設(shè)計外文資料翻譯 題 目 立柱式助力 機(jī)械手設(shè)計 學(xué) 院 機(jī)械工程學(xué)院 專 業(yè) 機(jī)械工程及自動化 班 級 機(jī)自 0902 學(xué) 生 學(xué) 號 指導(dǎo)教師 二〇一 三 年 三 月 十 五 日 濟(jì)南大學(xué)畢業(yè)設(shè)計外文資料翻譯 1 Manufacturing Engineering and Technology——Machining, 2021 The Design of Hand Column Type Power Machine Serope kalpak jian,Steven Shanghai Metallurgical Research Institute of Chinese Academy of Sciences Abstract Machine hand developed in recent decades as hightech automated production equipment. Industrial machine hand is an important branch of industrial machine hands. It features can be programmed tasks in a variety of expectations, in both structure and performance advantages of their own people and machines, in particular, reflects the people’s intelligence and adaptability. The accuracy of machine hand operations and a variety of environments the ability to plete the work in the field of national economy and there are broad prospects for development. With the development of industrial automation, there has been CNC marching center, it is in reducing labor intensity, while greatly improves labor productivity. However, the upper and lower mon in CNC marching processes material, usually still use manual or traditio
