在钻床上机动攻丝时,需经常频繁换向,易使电机过载烧坏,且操作很不方便,攻丝生产率也较低。这里推荐一种具有机械换向运动机构的可逆转攻丝工具。此工具经我们长期生产实践,证明其结构简单、制造方便、工作可靠、换向平稳而迅速,适合成批生产中使用。该工具的适用攻丝范围为M5～M16。工具结构如下:钻床主轴带动传动轴正向旋转,传动轴再通过齿轮轴和过桥齿轮带动摩擦套反向旋
In the mobile drilling on the machine, often frequent commutation, easy to overload motor burn, and the operation is very convenient, tapping productivity is also low. Here is a reversible reversing tapping tool with a mechanical reversing mechanism. This tool by our long-term production practice, to prove its simple structure, easy manufacture, reliable work, smooth and rapid commutation, suitable for mass production. The tool is suitable for tapping range M5 ~ M16. Tool structure is as follows: Drilling spindle drive shaft forward rotation, the drive shaft through the gear shaft and the bridge gear driven friction sleeve reverse rotation
