<p>A turret type tool post 1 includes a tool post body 10, a turret 11, a first drive shaft 14, an indexing drive mechanism 20 having a third drive shaft 21, a tool rotation drive mechanism 30 having a second drive shaft 31, a power transmission switching mechanism 40 having a hollow piston 42 and a hollow switching shaft 44 rotatably held in the piston 42, etc. When the piston 42 is moved to one side, the second drive shaft 31 is inserted into the switching shaft 44 in engagement, allowing rotational power to be transmitted to the second drive shaft 31. When the piston 42 is moved to the other side, gears 44a of the switching shaft 44 and the third drive shaft 21 are mated with each other, allowing rotational power to be transmitted to the third drive shaft 21. <IMAGE></p> |
