【摘要】：火箭、飛機(jī)、艦船等大型產(chǎn)品結(jié)構(gòu)復(fù)雜,多為分段制造后進(jìn)行總裝對(duì)接,此類分段大部件對(duì)接質(zhì)量直接影響總體裝配質(zhì)量。傳統(tǒng)的對(duì)接裝配工藝自動(dòng)化程度低、過(guò)度依賴專用檢具和人工經(jīng)驗(yàn)。部件對(duì)接裝配最佳匹配位置的確定,是提高大部件對(duì)接裝配效率和質(zhì)量關(guān)鍵之一,基于先進(jìn)測(cè)量設(shè)備和自動(dòng)化定位裝備,建立面向大部件最優(yōu)匹配位置的綜合評(píng)價(jià)指標(biāo)體系。首先,基于點(diǎn)集匹配、直線對(duì)齊、平面匹配和曲面匹配的數(shù)學(xué)模型,建立大部件對(duì)接結(jié)構(gòu)中各關(guān)鍵特征的裝配準(zhǔn)確度評(píng)價(jià)指標(biāo);其次,從制造準(zhǔn)確度和協(xié)調(diào)準(zhǔn)確度兩個(gè)方面構(gòu)建大部件對(duì)接裝配最優(yōu)匹配位置的綜合評(píng)價(jià)指標(biāo)體系,為部件制造質(zhì)量評(píng)估提供有效的評(píng)價(jià)方法,也為部件之間最優(yōu)匹配位置求解提供目標(biāo);最后,基于實(shí)驗(yàn)室自主研發(fā)的大部件對(duì)接平臺(tái),以筒段模擬件對(duì)接為研究對(duì)象,驗(yàn)證了這一綜合評(píng)價(jià)指標(biāo)體系在指導(dǎo)大部件裝配對(duì)接的有效性,與傳統(tǒng)工藝相比,可直接保證最優(yōu)對(duì)接位置,提高裝配質(zhì)量。
[Abstract]:The structure of rocket, aircraft, ship and other large products is complex, most of them are assembled and docked after subsection manufacture. The docking quality of this kind of segmented parts directly affects the overall assembly quality. Traditional docking assembly process automation degree is low, excessive reliance on special tools and manual experience. It is one of the key points to improve the efficiency and quality of the butt assembly of large parts to determine the optimal matching position of the parts. Based on the advanced measuring equipment and the automatic positioning equipment, a comprehensive evaluation index system for the optimal matching position of the large parts is established. Firstly, based on the mathematical models of point set matching, straight line alignment, plane matching and surface matching, the assembly accuracy evaluation indexes of key features in the docking structure of large parts are established. From two aspects of manufacturing accuracy and coordination accuracy, a comprehensive evaluation index system for the optimal matching position of butt joint assembly of large parts is constructed, which provides an effective evaluation method for component manufacturing quality evaluation. It also provides the goal for solving the optimal matching position between components. Finally, based on the large component docking platform independently developed in the laboratory, the paper takes the barrel analog docking as the research object. The effectiveness of the comprehensive evaluation index system in guiding the assembly and docking of large parts is verified. Compared with the traditional technology, the optimal docking position can be directly guaranteed and the assembly quality can be improved.
