PURPOSE:To position a spindle of a driving unit, governing the continuous rotation of a driving fixture applied to a rotary station machine in the constant angle stop by use of a motor separate from the rotation driving system. CONSTITUTION:The spindle 15 of the driving unit 2 is driven by a unit driving motor to be positioned in a constant angle stop engaged with a positioning pin 30 and an engaging groove 33. When the connection state with the spindle upper end is detected with a driving fixture lowered, a motor 23 for positioning is driven to retreat the positioning pin thereby assuring a higher reliability of the mechanical positioning. |
