1、1密級(jí)：公開汽車后橋環(huán)焊縫焊接專機(jī)設(shè)計(jì)TheStudyOfTheSpecialWeldingMachinesUsingInTheAutomobileBridge學(xué)院：專業(yè)班級(jí)：學(xué)號(hào)：學(xué)生姓名：指導(dǎo)教師：20年月11摘要汽車工業(yè)在中國(guó)已經(jīng)經(jīng)歷了60年的探索與發(fā)展，近年來(lái)，我國(guó)汽車生產(chǎn)水平大幅度提高，逐步接近世界先進(jìn)水平。焊接作為汽車生產(chǎn)工藝中必不可少且最關(guān)鍵的一環(huán)，國(guó)內(nèi)的焊接技術(shù)也達(dá)到了國(guó)際水準(zhǔn)。在專業(yè)性強(qiáng)且具有規(guī)則軌道的零部件進(jìn)行焊接時(shí)，使用焊接專機(jī)可以滿足焊接條件且經(jīng)濟(jì)實(shí)用。本設(shè)計(jì)為汽車后橋環(huán)焊縫焊接專機(jī)的設(shè)計(jì)。整個(gè)焊接專
2、機(jī)的工作包括氣動(dòng)卡盤卡緊與放松并按照焊接工藝要求進(jìn)行勻速轉(zhuǎn)動(dòng)，頂尖通過(guò)氣缸帶動(dòng)進(jìn)行左右移動(dòng)以便裝卸工件，焊槍上下移動(dòng)給工人留下操作空間，焊槍可以左右移動(dòng)以便使焊槍對(duì)準(zhǔn)焊縫位置。環(huán)焊縫焊接專機(jī)的結(jié)構(gòu)設(shè)計(jì)內(nèi)容包括床身，焊接小車，傳動(dòng)機(jī)構(gòu)，工裝卡具等。根據(jù)工件的加工需求，采用兩個(gè)對(duì)稱的焊接小車進(jìn)行一次性同時(shí)加工兩條焊縫。環(huán)焊縫的工作原理是焊槍不動(dòng)，要求工件進(jìn)行勻速轉(zhuǎn)動(dòng)，所以氣動(dòng)卡盤是整個(gè)設(shè)計(jì)的核心部件，根據(jù)工件的尺寸對(duì)卡盤的大小尺寸，工件的定位都是以卡盤中心為基準(zhǔn)。進(jìn)行設(shè)計(jì)另外設(shè)計(jì)內(nèi)容還包括了電機(jī)與減速機(jī)構(gòu)的選取，頂尖定位與傳動(dòng)，
