摘　　要：工程机械行业产品更新换代快,客户不仅要求产品结实耐用,还需要良好的外观。推土机产品重要安装座(如发动机、变速箱和驾驶室等)依靠大型设备精加工完成,护罩、护板和盖板等覆盖件安装座多数采取划线或工装组对。常规的定位工装采用厚板焊接、加工和装配,使用过程中穿销轴定位精度高,但制作周期长、成本高、重量大,频繁移动造成劳动强度大。在生产实践中逐步推广应用空间样板,不仅满足装配生产要求,且制造周期短、方便实用,提高组焊精度,避免装配干涉的频繁返修,适应了产品更新换代的步伐。Construction machinery industry product replacement very fast,customers not only require products strong and durable,but also need a good appearance.The important mounting seat of bulldozer products(such as engine,gearbox and cab,etc.)depends on the finishing of large-scale equipment.The conventional positioning fixture adopts thick plate welding,machining and assembly,and the pin shaft positioning has high accuracy,but the manufacturing cycle is long,the cost is high,the weight is big,and the frequent movement causes the labor intensity to be big.Our company gradually popularized the application of the space template in the production practice,not only meets the assembly production requirements,but also the manufacturing cycle is short,convenient and practical,improves the assembly welding accuracy,avoids assembly interference frequent repair,adapt to the pace of product replacement.
