C62A型敞车的侧梁上共有88个直径不等的孔,用于安装角柱、侧柱、脚蹬、绳挂、搭扣座和大票插等零部件。原用的加工工艺为样板划线和摇臂钻钻孔,费时、费力和质量差。我厂于1980年2月份着手设计一台侧梁多头钻,8月份开始调试,10月份投入生产运用。几个月的生产实践证明,其性能是令人满意的。这台侧梁多头钻具有:用微电机驱动的独立滚柱代替常用的桁架式滚道,采用多次定位、少用机电设备,节约能源,有利 There are 88 holes of unequal diameter on the side beam of the C62A gondola. It is used for the installation of corner posts, side columns, pedals, rope hangers, buckle seats and large ticket inserts. The original processing technology for the model crossed and rocker drill holes, time-consuming, laborious and poor quality. I plant in February 1980 to proceed with the design of a side beam bulldozers, commissioning started in August, put into production in October. A few months of production practice has proved that its performance is satisfactory. This side beam multi-head drill has: the use of independent micro-motor driven roller instead of commonly used truss-type raceway, the use of multiple positioning, less mechanical and electrical equipment, energy conservation, favorable
