摘　　要：针对道岔尖轨跟端热锻成形后,采用圆锯床二次锯切断面垂直度难以保证问题,通过设计工装、引进电动推杆机构,解决了不同种类产品在同一锯床上水平和竖向垂直度超差难题,操作方便、质量稳定,并且提高了加工效率。According the problem that it was difficult to ensure the secondary sawing section perpendicularity of circular sawing machine after the hot forging of the turnout switch rail root end, through the design tooling, introducing the electric push rod mechanism, solved the problem of different kinds of products in horizontal and vertical perpendicularity of the same sawing machine, the operation was convenient, the quality was stable, and the processing efficiency was improved.

关 键 词：尖轨跟端 钢轨锯切 垂直度 电动推杆 侧向定位
