I 摘要 焊接變位機(jī)運(yùn)動系統(tǒng)的設(shè)計(jì)是焊接變位機(jī)方案設(shè)計(jì)的核心內(nèi)容,而焊接變位機(jī)運(yùn)動自由度的確定是其前提條件。焊接變位機(jī)的關(guān)鍵是對變位機(jī)進(jìn)行最佳位置焊接所需要的運(yùn)動自由度的設(shè)計(jì),如平動或轉(zhuǎn)動的設(shè)計(jì)。 伸臂式焊接變位機(jī)是將工件回轉(zhuǎn),翻轉(zhuǎn),以便使工件上的焊縫置于水平和船形位置的機(jī)械裝置。伸臂式焊接變位機(jī)是應(yīng)用最廣泛的一種焊接變位機(jī),載重量一般不超過 1 噸。伸臂式焊接變位機(jī)的主體部分是翻轉(zhuǎn)機(jī)構(gòu)、回轉(zhuǎn)機(jī)構(gòu)、底座。本設(shè)計(jì)主要 論述了焊接變位機(jī)械的組成,工作原理,重點(diǎn)講述了其中的旋轉(zhuǎn)減速機(jī)構(gòu)的設(shè)計(jì),旋轉(zhuǎn)減速機(jī)構(gòu)通過電機(jī)驅(qū)動,經(jīng)過 帶傳動,二級蝸桿蝸輪減速器的傳動,起到減速和工作臺的旋轉(zhuǎn)運(yùn)動的效果。包括了電機(jī)的選擇,鍵的選擇,軸承的選擇等,還有帶輪傳動的計(jì)算,蝸輪蝸桿傳動的計(jì)算,蝸桿軸的校核,軸承的校核等一系列設(shè)計(jì)計(jì)算。 焊接變位機(jī)有利于實(shí)現(xiàn)最佳位置的焊接過程 、 提高工作效率、降低疲勞強(qiáng)度并達(dá)到良好的焊縫成型。 關(guān)鍵詞 : 焊接變位機(jī)械;帶傳動;蝸輪蝸桿傳動;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 .............................................................................................................
