4t焊接滾輪架機(jī)械設(shè)計(jì)本科論文

1、本科畢業(yè)設(shè)計(jì)〔論文〕4T 焊接滾輪架機(jī)械設(shè)計(jì)摘 要焊接裝備就是在焊接生產(chǎn)中與焊接工序相配合，有利于實(shí)現(xiàn)焊接生產(chǎn)機(jī)械化，自動(dòng)化，有利于提高裝配焊接質(zhì)量，促使焊接生產(chǎn)過(guò)程加速進(jìn)行的各種輔助裝置和設(shè)備。焊接滾輪架是借助主動(dòng)滾輪與焊件之間的摩接力帶動(dòng)焊接旋轉(zhuǎn)的變位機(jī)械。焊接滾輪架主要用于筒形焊件的裝配與焊接。焊接滾輪架按結(jié)構(gòu)形式分為兩類：第一類是長(zhǎng)軸式滾輪架。第二類是組合式滾輪架。本文主要對(duì)組合式 4T 焊接滾輪架進(jìn)行設(shè)計(jì)，并對(duì)軸、鍵等主

2、要構(gòu)件進(jìn)行了校核。結(jié)果說(shuō)明各主要部件符合要求。該滾輪架結(jié)構(gòu)簡(jiǎn)單，使用方便靈活，對(duì)焊件的適應(yīng)性很強(qiáng)。設(shè)計(jì)中充分的考慮了滾輪架的合理性和經(jīng)濟(jì)性等因素。關(guān)鍵詞：焊接；工裝夾具；滾輪架目 錄第一章 文獻(xiàn)綜述.........................................................1..............................................................
