图示攻丝动力头.可用来加工M1到M6的内螺纹(螺距为0.2～1毫米),可提高螺纹的质量并能实现攻丝过程的自动循环。 攻丝动力头由壳体,电动机,主轴部件,进给机构和控制系统组成。丝锥通过弹簧夹头装在主轴1上,主轴1又装在旋转螺母2中。动力由电动机3,经过齿轮4和5,传到轴套6,然后, The tapping head shown for machining M1 to M6 internal threads (pitch 0.2 to 1 mm) enhances the quality of the thread and enables an automatic cycle of tapping. Tapping power head from the shell, motor, spindle components, feed institutions and control systems. The tap is mounted on the spindle 1 by means of a collet chuck, which in turn is mounted in the swivel nut 2. Power from the motor 3, through the gears 4 and 5, reached the sleeve 6, and then,
