摩托车辐条式车轮轮毂钻机的改进

为了解决辐条式轮毂的辐条孔钻加工劳动效率低,PCD直径、位置度误差大,操作工疏忽、钻头刃磨等因素造成的孔位偏移、漏加工,轮毂报废率大等问题,借鉴其他群钻技术,通过不断研究、试验和改进,设计了在普通钻床上加一群钻头,按辐条孔的PCD直径均匀分布9只钻头,以轮毂外圆尺寸制作底座,确保底座和群钻同轴,辐条孔和轮毂同轴。改进后的专用群钻专机一次性可钻9只孔,大大提高了劳动效率及产品合格率,降低了生产成本。

Improvement of the Driller for the Hub of Motorcycle Spoke Wheels

In order to solve the problems with the spoke hole driller,such as lover efficiency,larger errors in PCD and position grades,carelessness of operators,shapening of drilling bit,which will cause port position drift,unmachined,big hub rejection rate.Based on the Ni Zhifu drill technology,this paper provides a new design that a group of drilling bits are added to the conventional machine-tool,with 9 bits distributed evenly according to the PCD of spoke port,making the base taking the outside circle as the dime...
