在普通小型钻床上加工左旋螺母,通常丝锥固定联结在主轴上,装夹麻烦、效率低,为此我们改进了夹头。夹头由锥体6、互换套2、止销5等组成。锥体6的锥柄与钻床主轴的锥度吻合,固定所需的互换套2,止销5起稳定长柄丝锥1的作用,不至于脱落,弹簧3根据不同规格的丝锥可以调节松紧,工作时由互换套2传递扭矩,轴向位置由止销5保证(必要时可在长柄丝锥尾部相应的位置磨一小
In ordinary small drilling machine processing left-handed nut, usually tap fixedly connected to the spindle, the clamping trouble, low efficiency, for which we have improved chuck. Chuck from the cone 6, interchangeable sets 2, 5-pin and other components. Taper cone cone 6 drill spindle taper, the necessary interchangeable sets of fixed 2, pin 5 stable long handle tap 1 does not fall off, the spring 3 according to different specifications of the tap can be adjusted tight, work When the interchangeable sleeve 2 torque transmission, the axial position by the pin 5 to ensure (if necessary, the corresponding position in the long handle taps a small mill
