摘要
针对和谐号动车摇臂轴在两头圆柱面上进行多油孔加工时,由于不易装夹、调整费时,给加工带来了一定困难且加工精度难以保证的问题,且该产品批量又较大,为了提高生产效率,保证加工质量,进行了油孔加工的钻模设计制造,投入使用后取得良好的生产效果,保证了产品品质和较大的经济效益。
When multiple oil holes on both ends cylindrical surface of rocker-arm shafts of CRH train are processed, it is hard to fasten them. In addition, the adjustments are also time-consuming, which brings difficulties to the processing. Besides, machining accuracy is difficult to guarantee, too. Therefore, to realize the bulk production, improving production efficiency as well as assuring the processing quality, drill jigs are designed and manufactured, which not only produces a good effect, but also ensures good qualities and economic benefits.
