汽車(chē)后橋環(huán)焊縫焊接專(zhuān)機(jī)設(shè)計(jì)
摘要
汽車(chē)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(chē)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(chē)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(zhuān)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(zhuān)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(chē)后橋環(huán)焊縫焊接專(zhuān)機(jī)的設(shè)計(jì)。整個(gè)焊接專(zhuān)機(jī)的工作包括氣動(dòng)卡盤(pán)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(zhuān)機(jī)的結(jié)構(gòu)設(shè)計(jì)內(nèi)容包括床身,焊接小車(chē),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(chēng)的焊接小車(chē)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(pán)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(pán)的大小尺寸,工件的定位都是以卡盤(pán)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),焊接小車(chē)的設(shè)計(jì)等。

Abstract
Automobile industry in China has gone through 60 years of exploration and development,in recent years,China's automobile production levels increase the dsignificantly,Step by step closer to the world's advanced level.Welding as a car is necessary in the production process and the key link,Domestic welding technology has reached the international level.In orbits and with specialized components during welding,using the welding machine can satisfy the welding conditions and the economic and practical.
This design for the automobile rear axle seam welding machine design.Work of the whole welding machine including pneumatic chuck card tight and relaxation and uniform rotation in accordance with the requirements for welding process.Top move around to unloading workpieces by pneumatic cylinders,Welding torch left workers operating space to move up and down,Welding torch can move around in order to make the torch on the weld position.
Seam welding machine structure design content including lathe bed seam the welding machine tstructure design content including lathe bed,the welding tractor, transmission mechanism.Due to the workpiece requirements,Using two symmetrical welding carriage to one-time processing two weld at the same time.The working principle of girth weld is a welding torch,So the pneumatic chuck is the core component of the whole design,So according to the size of the size of the workpiece to chuck size,So the root workpiece positioning are chuck center as a benchmark.To carry on the design and design content includes the selection of motor and the retarding mechanism, top location and transmission, the design of the welding carriage, etc.
Keywords:Automobile driving axle; Welding machine; Pneumatic chuck.
Welding tractor
