Abstract
PURPOSE:To rotate a spindle both in the regular and reverse directions and provide precision boring by mounting a tap on a drive shaft rotating in a single piece with the spindle with possibility of moving in the axial direction, moving in accordance with the pitch of thread provided at the tap in the axial direction through a guide, and sensing the amount of movement. CONSTITUTION:A driver 7 is mounted on a spindle 4 to rotate consolidated. A support 10 in installed on this driver 7 through a bearing 9 in such a way as not rotating, and a guide 19 is fitted at its inner surface 21. A female thread 20 is formed at this guide 19, while a male thread on a rotary shaft 15 which is fitted with a tap 16. The rotary shaft 15 is mounted on the driver 7 with possibility of moving in the axial direction to transmit rotation of the driver. Rotation of the rotary shaft 15 is moved in the axial direction by meshing of the male thread 18 with female thread 20 in accordance with the pitch, and the amount of motion is conducted to a moving mechanism 29, and microswitches 55, 58 of a sensing mechanism 49 are turned on and off to rotate the spindle 4 in the regular or reverse direction. Accordingly high precision tapping is made practicable with simple construction.
