PURPOSE:To improve the responsiveness of a parts fitting device and reduce the transmission error of the device by coaxially providing a rotary motor and cylindrical linear motor which rotate and vertically move a nozzle with the axis of the nozzle in its nozzle head and enabling the needles of the motors to rotate or vertically move together with, the nozzle. CONSTITUTION:A nozzle head 3 is provided with a nozzle 19 for attracting parts by suction, and a rotary motor 6 and cylindrical linear motor 11 are coaxially arranged with the axis of the nozzle 19 so that the nozzle can be rotated or vertically moved by means of the motors 6 and 11. The rotary motor 6 is constituted of a permanent magnet synchronous type servo motor and the linear motor 11 is a movable coil linear servo motor. The driving force of the motor 6 is transmitted to the nozzle 19 (direct acting shaft 16) through a transmitting system composed only of a ball spline 18 and the driving force of the linear motor 11 is directly transmitted to the nozzle 19 (direct acting shaft 16). |
