技術(shù)進(jìn)步的最重要和最有效的發(fā)轉(zhuǎn)方向之一就是實(shí)現(xiàn)生產(chǎn)的過程，其中包括焊接過程的全盤機(jī)械化和自動(dòng)化。關(guān)鍵詞:焊接；翻轉(zhuǎn)機(jī)構(gòu)；結(jié)構(gòu)設(shè)計(jì)ABSTRACT This 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 ponents 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 can carry out an inside out and inside out anization, and carried on the analysis to the dynamic state stability, the result enunciation:Inside out anization at inside out is continuously inside out anization covers the space small, the
