摘要： Disclosed is an actuator having a frame in which a drive source and a slider displaced under the action of the drive source are held, and an actuator arrangement comprising a plurality of actuators connected to each other by connecting devices. A beam member, which constitutes the frame, has a concave portion defined in a side thereof and the drive source is held in the concave portion. A slider base is held in the concave portion and includes the slider displaced along the concave portion. A cover is used to cover the concave portion defined in the beam member. The beam member has grooves defined in respective outer sides thereof, which have substantially T-shaped cross sections and enable other beam members to be mounted to the beam member. The grooves are defined along the longitudinal direction thereof so as to be substantially identical in structure to one another. According to the above construction, either other beam members or the actuators can be connected to one another by means of the grooves so as to assemble a desired actuator arrangement having a desired shape, thereby making it possible to place the actuator arrangement on a production line in a factory.

摘要： A rotary driving source is connected to one end of a frame. The rotary driving force of the rotary driving source is transmitted to a slider by the aid of a driving pulley, a belt member, and a driven pulley. The slider is displaced in the axial direction of the frame while being guided by a guide mechanism. Each of the frame and the slider is formed of, for example, an aluminum alloy. First guide rails are installed in the frame and second guide rails are installed in side surfaces of the slider. The first guide rails and the second guide rails are formed of a metal material subjected to a hardening treatment.

摘要： An actuator comprises a pump-driving section which is driven and rotated by a current, and a pump mechanism which is connected to the pump-driving section and which sucks/discharges a pressure oil. A cylinder mechanism, which has a piston that is displaceable in the axial direction by being supplied with the pressure oil, is provided on the pump-driving section and the pump mechanism. The amount of discharge of the pressure oil to the cylinder mechanism is adjusted by freely changing the angle of inclination of a tilting member provided in the pump mechanism.

摘要： An electric actuator has a body with a hole defined therein and an electric motor fixed to an end of the body. The electric motor has a rotatable shaft to which a feed screw is coaxially connected, and a feed nut is threaded over the feed screw. The hole receives an elongate cylindrical tubular member slidably fitted therein which surrounds the feed screw. The feed nut is secured to an end of the tubular member, and a support for feeding a workpiece supported thereon is fixed to the other end of the tubular member. The feed screw, which serves as a drive force transmitting shaft, is protected by the surrounding tubular member from the deposition thereon of dust, dirt, or other foreign matter and hence from unwanted shutdown or breakage.
