【正文】 于最理想的位置進(jìn)行焊接，使焊縫質(zhì)量的提高有了可靠的保證，它是焊接各種軸類、盤類、筒體等回轉(zhuǎn)體零件的理想設(shè)備，同時(shí)也可用來焊接機(jī)架、機(jī)座、機(jī)殼等非長(zhǎng)形工件。 本次 論文處于對(duì)大學(xué)四年所學(xué)的知識(shí)進(jìn)行的一次綜合性的梳理及應(yīng)用，對(duì)學(xué)生的綜合能力進(jìn)行的一次較為實(shí)質(zhì)性的鍛煉。 再者，工程機(jī)械大部分結(jié)構(gòu)件很不規(guī)則，如裝載機(jī)的前車架、挖掘機(jī)的大臂等類工件，焊縫復(fù)雜，外形大且重量較重，靠行車或其它吊裝設(shè)備人工翻轉(zhuǎn)，不僅頻繁占用吊裝設(shè)備，焊接效率低，而且現(xiàn)場(chǎng)操作 不規(guī)范 ，存在一定的安全隱患。但是如果沒有焊接變位機(jī)，對(duì)于復(fù)雜結(jié)構(gòu)件內(nèi)的一些立焊縫、仰焊縫等單純靠人工調(diào)整至容易焊接的平焊或船焊位置是不可能的。 本次論文主要介紹 伸臂式旋轉(zhuǎn)焊接變位機(jī)的總體設(shè)計(jì)及其裝配，重點(diǎn)介紹其中的回轉(zhuǎn)機(jī)構(gòu)的設(shè)計(jì)及其組裝，由于作者水平有限，時(shí)間倉促，錯(cuò)誤再所難免，還請(qǐng)讀者朋友們批評(píng)指正。許多產(chǎn)品，例如大型的超高壓容器，除采用焊接工藝 外，難以設(shè)想有更好的方法。許多傳統(tǒng)的鑄鍛制品也有焊接制品或鑄 焊，鍛 焊制品所代替。 鍵的選擇及校核 ......................................................................................................11 第 4 章 焊接變位機(jī)的總體設(shè)計(jì) ............................................................ 14 伸臂梁的設(shè)計(jì)計(jì)算： ............................................................................................ 14 底座和箱體的簡(jiǎn)單設(shè)計(jì) ......................................................................................... 15 結(jié)論 ........................................................................................................... 16 參考文獻(xiàn) ................................................................................................... 17 致謝 ........................................................................................................... 18 附件 1 ........................................................................................................ 19 IV 附件 2 ........................................................................................................ 23 1 前言 隨著現(xiàn)代工業(yè)的發(fā)展和焊接技術(shù)的不斷進(jìn)步，焊接作為一種金屬連接的工藝方法。 關(guān)鍵詞 ： 焊接變位機(jī)械；帶傳動(dòng)；蝸輪蝸桿傳動(dòng)；減速器 II Abstract The design of the moving system of the welding positioner is the core content of the scheme design,but the system depends on the moving freedom`s key part of the design of the welding positioner is the design of the moving freedom, according to the best welding position. The main parts of the welding positioner include overturning machinery, circumgyrating machinery and the armextending welding posioner is used most widely ,the load is less than one armextending welding positioner is the machine which makes the workpiece circumgyrate and overturn to make the welding line on the workpiece park the level direction and cymbate position. The welding positioner`s makeup and operating principle make up of the paper ,which disserates the design of the turning gear of the machine .The belt driving and two stage worm wheel retarder make the turning gear realize the man`s anticipating use of the techogenerator which will feed back the instant speed to the generator and then the controller will adjust the speed makes sure of the high welding line quality. Welding positioner is in favor of the welding process to achieve the best possible position,improving efficiency,reducing the fatigue strength,and forming a good weld. Key words:welding posioner,belt drive,worm drive,reducer III 目錄 摘要 .............................................................................................................
