摘要： The invention relates to a method for manufacturing vacuum suction pads, in which, in addition to reductions of contaminant components, the material of vacuum suction pads is subjected to an improved surface treatment which prevents deposition of pad marks on work surfaces and reduces frictional resistance of suction pads on work surfaces to lessen their fatigue. Suction pads of synthetic rubber, to be connected to a vacuum source, are each formed with a thin halogenation-hardened layer at least on a sucking surfaces to be held in contact with a work surface.

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.

摘要： Disclosed herein is a mechanism for locking the angular movement of a suction pad. The mechanism comprises a tubular body fitted to a root part of the suction pad and having a flange; a cover member attached to a moving assembly for displacing the suction pad; a first bush having a slide resistance lower than the tubular body and fitted to the flange of the tubular body; and a second bush having a slide resistance lower than the cover member and fitted to the inside of the cover member. The first bush and second bush are engaged with each other in such a manner that alternating concavities and convexities of the first bush are meshed with alternating convexities and concavities of the second bush, respectively, whereby the displacement of the suction pad in its axial direction is guided, and the angular movement of the suction pad is prevented.

摘要： A suction pad for attracting a workpiece under vacuum has a cylindrical base to be connected to a vacuum source, and a skirt integrally joined to the base, for developing a vacuum therein to attract the workpiece. The suction pad can be kept at a temperature suitable for the workpiece, by an electric heater which is controlled in response to a temperature signal from a temperature sensor embedded in the skirt. The suction pad with the controlled temperature does not cause problems which would otherwise result from the different temperatures of the suction pad and the workpiece.

摘要： An electric actuator includes a hollow actuator housing, an electric motor connected to the hollow actuator housing, a feed screw shaft coupled to the drive shaft of the electric motor, for transmitting rotational drive power from the electric motor, and a spline tube disposed in the hollow actuator housing in surrounding relationship to the feed screw shaft and held in engagement with the feed screw shaft, for displacement axially with respect to the hollow actuator housing with the rotational drive power transmitted by the feed screw shaft. Since the feed screw shaft is surrounded by the spline tube, dust and dirt particles are prevented from being deposited on the feed screw shaft.
