螺纹牙底R圆弧翻转修整器设计

Design of R-arc turning dresser for screw thread

由于航标HB过盈螺纹牙底轮廓为圆弧状,实际生产中需要进行磨削加工。传统所使用的砂轮修正方式为手工修整,不仅效率低、质量波动性大,而且还存在着显著的人身安全隐患。为此设计了一种砂轮翻转修整器用于取代手工修整。该装置采用滚压轮并具备微调机构以快速找正砂轮进行修整,具有安装方便、操作简单、修整效率高、加工质量稳定等特性。该装置已在实际投入生产使用,修整砂轮所需时间大为缩短。

Because the bottom profile of the interference screw thread of HB is in arc shape,the grinding is needed in actual production. The traditional grinding wheel repair method is manual dressing,which is not only low efficiency,high quality volatility,but also there are significant personal safety hazards. Design a new kind of grinding wheel turning dresser which can replace manual dressing. The invention adopts the rolling wheel and has the fine tuning mechanism to quickly find the positive grinding wheel for dressing,which has the characteristics of convenient installation,simple operation,high efficiency and stable processing quality and so on. The proposed device has been put into use in practice,and the time required for dressing the grinding wheel is shortened.
