一種焊接翻轉(zhuǎn)機(jī)構(gòu)設(shè)計(jì)摘 要本文闡述了大型缸體翻轉(zhuǎn)提升機(jī)構(gòu)的設(shè)計(jì)，設(shè)計(jì)只講解了機(jī)械結(jié)構(gòu)設(shè)計(jì),設(shè)計(jì)主要是為了使得缸體在生產(chǎn)過程中更容易加工，更容易焊接。機(jī)械結(jié)構(gòu)部分采用了軸類轉(zhuǎn)動(dòng)和大平面式定位裝置組成。包括整體系統(tǒng)設(shè)計(jì)、翻轉(zhuǎn)機(jī)構(gòu)的設(shè)計(jì)、框架的設(shè)計(jì)等。在設(shè)計(jì)中對(duì)傳動(dòng)軸和基本部件的強(qiáng)度進(jìn)行了校荷，來保證其強(qiáng)度要求同時(shí)需要進(jìn)行焊接部分的強(qiáng)度校荷，來最終確定設(shè)計(jì)方案。焊接翻轉(zhuǎn)機(jī)構(gòu)的結(jié)構(gòu)尺寸、平穩(wěn)性、翻轉(zhuǎn)的連續(xù)性以及制造成本對(duì)提高焊接效率和保證安全性有很大的影響，研究了可以實(shí)現(xiàn)原地低位的翻轉(zhuǎn)機(jī)構(gòu)，并對(duì)動(dòng)態(tài)穩(wěn)定性進(jìn)行分析，結(jié)果表明：翻轉(zhuǎn)機(jī)構(gòu)在翻轉(zhuǎn)時(shí)連續(xù)平穩(wěn)。翻轉(zhuǎn)機(jī)構(gòu)占地空間小，制造成本低，具有良好的應(yīng)用前景，在國內(nèi)外焊接生產(chǎn)線上有很高的推廣價(jià)值。關(guān)鍵詞:焊接；翻轉(zhuǎn)機(jī)構(gòu)；結(jié)構(gòu)設(shè)計(jì)一種焊接翻轉(zhuǎn)機(jī)構(gòu)設(shè)計(jì)1ABSTRACTThis paper expounds the mechanism design of large converter overturning, only on the design of mechanical structure design, the design is to make the boiler is easier to process in the production process, easy welding. The mechanical structure part adopts the structure of modular fixture chain turnover, hydraulic lifting. Including the transmission system design, the turnover mechanism design, hydraulic cylinder design. In the design of the transmission shaft and the basic components of the strength of the school charge, to ensure its strength requirements and the need for welding part of the strength of the school charge, to determine the final design scheme.Weld the structure size, steady, inside out consecution and manufacturing costs of the inside out machine to weld to the exaltation the efficiency and the assurance safeties contain very big influence.Studying can carry out an inside out and inside out organization, and carried on the analysis to the dynamic state stability, the result enunciation:Inside out organization at inside out is continuously steady.The inside out organization covers the space small, the manufacturing cost is low, having the good applied foreground, producing in the domestic and international welding on-line have the very high expansion value.Key words: Converter;Inside out organization;architectural design2目 錄摘 要 .IIIABSTRACT IV目 錄 .V1 緒論 .11.1 課來題源及研究的目的和意義 .11.2 國內(nèi)外設(shè)備目前的發(fā)展?fàn)顩r 11.3 課題研究方法和手段 .11.4 課題應(yīng)達(dá)到的基本要求 .21.4.1 翻轉(zhuǎn)機(jī)構(gòu)設(shè)計(jì)指導(dǎo)思想 21.5 設(shè)計(jì)任務(wù)書的基本要求 .22 翻轉(zhuǎn)機(jī)構(gòu)整體方案設(shè)計(jì) .32.1 總體設(shè)計(jì)方案 .32.1.1 設(shè)計(jì)目的 32.1.2 設(shè)計(jì)原理 32.2 翻轉(zhuǎn)機(jī)構(gòu)系統(tǒng)概述 52.2.1 翻轉(zhuǎn)機(jī)構(gòu)系統(tǒng)組成 .52.2.2 翻轉(zhuǎn)機(jī)構(gòu)的工作原理 .52.2.3 翻轉(zhuǎn)機(jī)構(gòu)的功能要求 .52.3 翻轉(zhuǎn)機(jī)構(gòu)總體方案設(shè)計(jì)與比較 52.3.1 翻轉(zhuǎn)機(jī)構(gòu)總體方案設(shè)計(jì) 52.3.2 翻轉(zhuǎn)機(jī)構(gòu)的比較選擇 .83 翻轉(zhuǎn)機(jī)構(gòu)結(jié)構(gòu)零部件的設(shè)計(jì) .93.1 機(jī)構(gòu)框架設(shè)計(jì) 93.1.1 框架結(jié)構(gòu)材料 .93.1.2 結(jié)構(gòu)的成形方式 103.2 翻轉(zhuǎn)機(jī)構(gòu)軸的設(shè)計(jì) .103.2.1 軸徑的確定 .123.2.2 軸的結(jié)構(gòu)設(shè)計(jì) 123.3 踏板、轉(zhuǎn)盤及手輪的設(shè)計(jì) .153.4 平衡塊的設(shè)計(jì) 164 標(biāo)準(zhǔn)件的選用 .164.1 軸承的選擇 174.1.1 軸承的基本概念 .174.1.2 滾動(dòng)軸承的主要類型、比較和選擇 .174.1.3 軸承型號(hào)的確定 .20一種焊接翻轉(zhuǎn)機(jī)構(gòu)設(shè)計(jì)34.1.4 軸承的壽命 .224.2 其它標(biāo)準(zhǔn)件選用 224.2.1 軸承座的選用 .224.2.2 軸套的選用 .234.2.3 開口銷的選用 .254.2.4 壓簧的選用 264.2.5 墊片的選用 264.2.6 鍵的選用 275 翻轉(zhuǎn)機(jī)構(gòu)的焊接與裝配 .295.1 框架的焊接 .295.1.1 選擇焊接方法 .295.1.2 確定焊接的形狀、尺寸和下料方法 .295.1.3 確定焊接接頭、坡口形式和坡口邊緣的加工方法 .305.1.4 焊接方案的確定 .305.2 零部件的裝配 305.2.1 機(jī)器裝配的基本概念 .305.2.2 零件在裝配中連接種類 .315.2.3 裝配方法 .325.2.4 裝配方案的確定 .335 結(jié)論 .33致謝 .34參考文獻(xiàn) .35
