摘 要
汽車發(fā)動(dòng)機(jī)在高速旋轉(zhuǎn)下發(fā)熱量很大，尤其是大功率發(fā)動(dòng)機(jī)，在高溫下對(duì)汽車發(fā)動(dòng)機(jī)潤(rùn)滑系統(tǒng)的可靠性要求比較高。而機(jī)油冷卻器可以保持發(fā)動(dòng)機(jī)工作狀態(tài)下可靠的潤(rùn)滑。提高其工作可靠性和壽命，降低發(fā)動(dòng)機(jī)本體的制造精度，對(duì)于車載發(fā)動(dòng)機(jī)來(lái)說(shuō)是必不可少的配套裝置。隨著我國(guó)現(xiàn)代化進(jìn)程的加快，汽車工業(yè)的迅猛發(fā)展，機(jī)油冷卻器市場(chǎng)中的需求越來(lái)越大，圓盤機(jī)油冷卻器由于其結(jié)構(gòu)及性能的優(yōu)勢(shì)，更是需求加大。
機(jī)油冷卻器的裝配工藝過(guò)程是其制造過(guò)程中非常重要的環(huán)節(jié)，裝配質(zhì)量的好壞直接影響機(jī)油冷卻器的密封性能?？墒?，由于機(jī)油冷卻器的結(jié)構(gòu)特點(diǎn)限制，長(zhǎng)期以來(lái)，在國(guó)內(nèi)外這一工藝過(guò)程一直靠人手工操作，效率低，工作勞動(dòng)強(qiáng)度大，且裝配質(zhì)量過(guò)多地受到人為因素的影響，致使機(jī)油冷卻器質(zhì)量的穩(wěn)定性和可靠性不高。隨著企業(yè)用戶需求量的增加，揚(yáng)州通洋機(jī)油冷卻器有限公司準(zhǔn)備建造一條針對(duì)不銹鋼圓盤式機(jī)油冷卻器的自動(dòng)裝配線?；跈C(jī)油冷卻器的結(jié)構(gòu)特點(diǎn)限制，采用完全的自動(dòng)裝配是不現(xiàn)實(shí)的。因此在原來(lái)的手工裝配線，開發(fā)一條半自動(dòng)裝配線符合該廠目前的實(shí)際情況。這既可以提高機(jī)油冷卻器的裝配質(zhì)量，又可以節(jié)約大量成本。自動(dòng)裝配線由機(jī)械系統(tǒng)（包括裝配輸送線、裝配機(jī)械手、定位裝置、壓緊設(shè)備等）、氣壓系統(tǒng)、電氣系統(tǒng)和PLC控制系統(tǒng)等部分組成. 無(wú)疑它將是機(jī)、電、氣一體化的產(chǎn)品。
關(guān)鍵詞：機(jī)油冷卻器，自動(dòng)化裝配線，壓力機(jī)。
Abstract
Automobile engine in high-speed rotary would get heat. Under the high temperature, a car's engine lubrication system’s reliability requirements are relatively high, especially with high-power engine. And the oil cooler can maintain engine under reliable lubrication in work, improving their reliability and life expectancy, lowering precision of engine manufacturing. It is an essential supporting device for the truck engine. With the acceleration of the process of modernization and the rapid development of the auto industry, the demand of oil cooler market increases quickly, especially for disk-oil coolers, because of its advantages of structure and properties.
Oil cooler assembly process is a very important part in the manufacturing process. The assembly quality will do a direct impact on the oil cooler sealing performance. However, as the restrictions of the oil cooler of the structure, for a long time, the assembly process has relied on hand not only at home but also abroad. It is inefficient, labor-intensive. And assembly quality is mainly due to artificially ,this made the stability and reliability of oil cooler is not high.
An automatic assembling line for stainless steel flat-fin oil cooler has been planed to set up at Yangzhou Tongyang Oil Cooler Co., Ltd. However, due to its structure feature, it’s not realistic to set up the fully equipped automatic assembly line of oil cooler. So based on the original manual assembling line, building semiautomatic assembly line is a ideal method which accord with real situation with the this firm at present. It can not only improve the assembling quality of oil cooler, but also save a lot of money.
Automatic assembly line combines mechanical systems (including assembly line, assembly manipulator, positioning devices, compaction equipment, etc.), pressure systems, electrical systems and PLC control system. Obviously it is a composite product including machine, electricity, gas driving etc.
Keywords : oil cooler, automated assembly lines, press machine .
