钻帽式攻丝接头的形状和大小与一般钻帽相似,只要将它插入台式钻床的主轴锥孔内,就可以进行攻丝了。如图所示,莫氏锥柄1插入台式钻床的主轴锥孔内,当主轴正转时,由于挡杆18靠在钻床的立柱上,体部13将保持不动,而上部的锥齿轮6就跟着正转。这时向下扳动钻床的手柄,使其主轴下降,当丝锥插进螺纹底孔时,摩擦轴15的上锥体与上部锥齿轮的内锥孔结合,由此产生的摩擦力矩驱使丝锥进行攻丝。攻丝到位后,抬起钻床的手柄,使其主
The shape and size of the drill-cap tapping connector is similar to that of a typical drill cap, as long as it is inserted into the spindle taper hole of a bench drill, tapping can be performed. As shown in the figure, the Morse taper shank 1 is inserted into the spindle taper hole of the bench drilling machine. When the spindle is rotated forwardly, the body 13 will remain intact due to the stop bar 18 resting on the column of the drilling machine, while the upper bevel gear 6 Just follow the turn. At this time, the handle of the drilling machine is pulled downward to lower the spindle. When the tap is inserted into the bottom hole of the thread, the upper cone of the friction shaft 15 is combined with the inner cone of the upper bevel gear, and the friction torque generated thereby drives the tap Tapping. After tapping is in place, lift the handle of the drilling machine to make it the main one
