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 – 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. Key words: welding positioner。 turning gear。 課題研究的意義及現(xiàn)狀 .......................................................................................... 5 論文主要研究內(nèi)容 .................................................................................................. 5 第 2 章 回轉(zhuǎn)機(jī)構(gòu)中非標(biāo)準(zhǔn)件的設(shè)計(jì)計(jì)算及校核 ................................... 7 回轉(zhuǎn)主軸的設(shè)計(jì)計(jì)算和校核 …………………………………………… ...……… 7 減速器的設(shè)計(jì)計(jì)算 …………………………… ...………………………………… 9 帶傳動的設(shè)計(jì)計(jì)算 ………………………………… ...………………………… ..26 第 3 章 回轉(zhuǎn)機(jī)構(gòu)中標(biāo)準(zhǔn) 件的選擇及校核 ............................................. 29 軸承的選擇及校核 ................................................................................................ 29 鍵的選擇及校核 .................................................................................................... 34 電動機(jī)密封圈的選擇及校核 .................................................... 36 第 4 章 焊接變位機(jī)械其它機(jī)構(gòu)的簡單設(shè)計(jì)概述 ................................. 37 伸臂梁的設(shè)計(jì)計(jì)算 ................................................................................................ 37 傾斜機(jī)構(gòu)中減速器的設(shè)計(jì)計(jì)算 ............................................................................ 37 底座和箱體的設(shè)計(jì) ................................................................................................ 37 結(jié)論 ........................................................................................................... 39 參考文獻(xiàn) ................................................................................................... 40 致謝 ........................................................................................................... 41 附件 1 ........................................................................................................ 42 IV 附件 2 ........................................................................................................ 53 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。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。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。 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,其中包括回轉(zhuǎn)機(jī)構(gòu),傾斜機(jī)構(gòu),箱體,底座的設(shè)計(jì)及其計(jì)算,重點(diǎn)介紹其中的回轉(zhuǎn)機(jī)構(gòu)的設(shè)計(jì),回轉(zhuǎn)機(jī)構(gòu)主要包括工作臺,回轉(zhuǎn)主軸,二級蝸輪蝸桿減速器,帶傳動部分,電動機(jī)等。 編者
