近年来,由于我国高速公路的迅速发展,发达的东南部地区长途运输量日益增长,西部开发又迅速形成了另一条繁忙的物流渠道。这就给载重量大、远距离、高效率的重型卡车提供了巨大的舞台。我国汽车企业也开始抓住这一大好形势,已由过去大量生产的5吨中型卡车向生产8吨、10吨、13吨、15吨、20吨重型卡车大转型。重型卡车上的各关键总成的规模化生产是汽车企业生产重型卡车的关键。后桥壳总成的自动化焊接生产也是其中的关键工序。根据这一情况,成都电焊机研究所专用电焊机公司研制出了重型汽车后桥壳成套焊接设
In recent years, due to the rapid development of China’s expressways, the long-distance transport volume in the developed southeastern regions has been increasing. Western development has rapidly formed another busy logistics channel. This provides a huge stage for heavy-duty, long-distance, high-efficiency heavy trucks. China’s auto companies have also begun to seize this favorable situation. The large-scale production of 5-ton medium-duty trucks has transformed the production of 8-ton, 10-ton, 13-ton, 15-ton, and 20-ton heavy trucks. The large-scale production of key assemblies on heavy trucks is the key to the production of heavy trucks by auto companies. The automated welding production of the rear axle housing assembly is also one of the key processes. According to this situation, the Chengdu Electric Welder Research Institute dedicated welding machine company developed a complete set of heavy-duty vehicle rear axle housing welding
