PURPOSE: To provide a component-mounting device, capable of downsizing a linear actuator and a rotary actuator and capable of speedily and accurately positioning a component in the Z-axis direction and theΘ-axis direction. CONSTITUTION: A component-mounting device for driving a nozzle 35, which sucks a component in a rotation and vertical direction comprises: the rotary actuator 20; and the linear actuator 2, having a stator connected to a stator of the rotary actuator in a disabled relative movement. A spline shaft 24 is coupled with a rotary shaft of the rotary actuator, and a nozzle coupling shaft 26, which is allowed to move in straight and provided by a suction nozzle at its lower end, is engaged with the spline shaft. A hollow holder 30, surrounding the nozzle coupling shaft 26 via a rotary bearing 31, is coupled to a movable part of the linear actucator 2, and the hollow holder 30 is fixed to the stator of the linear actuator 2 via a linear guide 8. |
