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.

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 suction pad assembly for holding a work by suction includes a suction pad and a connector. The suction pad comprises a root part connected to a vacuum and suction source through the connector and a skirt part integrally joined to the root part. The connector has an entirely protrudent part in a noncircular form in transverse section. The root part has a recess into which the noncircularly protrudent part of the connector is fitted. Alternatively, the root part has an entirely protrudent part in a noncircular form in transverse section and the connector has a recess in a noncircular form in transverse section, into which the protrudent part of the root part is fitted. A process for the production of the suction pad assembly comprises forming a skirt part of a suction pad body thinly so as to conform to the shape of the surface of a work and at the same time, forming a recess or protrudent part in or on a root part of the suction pad body; causing the skirt part to conform to the shape of the surface of the work; hardening the skirt part in a state that the skirt part has been caused to conform to the shape of the surface of the work; and then fitting a protrudent part or recess of a connector into or over the recess or protrudent part of the root part to integrate the connector and suction pad body with each other.
