摘要： A weld-position detector, attached to an automatic welding machine such as a welding robot, having three independently produced indispensable units, i.e., a laser-beam projecting unit for projecting a detection laser-beam, a scanning unit for directing the detection laser-beam towards weld portions of a workpiece and scanning the detection laser-beam across the welded portions, and a light-receiving unit for detecting the detection laser-beam reflected by the workpiece to thereby detect the position of the weld portions. The weld-position detector further having a fixture provided with reference faces on which the three independent units are accurately mounted. The scanning means having a movable reflecting mirror is provided with an optical axis adjusting unit for adjusting the position and the posture of the scanning unit so as to adjust the optical axis of the detection laser-beam until the optical axis of the detection laser-beam, after being reflected from the workpiece, arrives at the light-receiving unit.

摘要： A small-locus machining apparatus is attached to the distal end of a wrist of a robot but operable independently of a robot body. First and second drives of the apparatus are mounted on a base in such a manner that respective output spindles are parallel with each other. First and second rotational arms are coupled to the output spindles through decelerators, which are directly connected to the drives, allowing rotation in a plane orthogonal to the output spindles. These rotational arms and links interconnecting the rotational arms constitute a link mechanism having, for example, five joints. A tool is attached to this link mechanism, and the rotational amounts of the first and second arms are detected to determine the coordinate position of the tool.

摘要： In a vibration wave linear motor, a vibrator stably operates with a simple and small configuration. Both ends of a movable guide member are held by shaft bearing long holes to freely oscillate, and an angle of an inclination φ occurs according to the move of the vibrator. An inner wall of an erecting part of a supporting part also serves as a stopper, and regulates the move of the vibrator in a position where the inclination of the movable guide member becomes θ>φ at the maximum. As a result, the inclination of the movable guide member is always kept to be within the range of θ>φ. A problem that the inclining movable guide member contacts a portion other than a driving contacting part is prevented.

摘要： A vibration wave linear motor comprises a vibrator unit having two driving contacting parts which are respectively formed on top and bottom surfaces of the vibrator unit, two guide members guiding the running of the vibrator unit by sandwiching the vibrator unit in parallel with the running direction. The upper guide member is fixed to the supporting member. The lower guide member is held in shaft bearing long holes, pressed upward by coil springs within hollow convex parts. The vibrator unit self-runs and moves forward and backward between the two guide members with an ultrasonic vibration. A linking pin fixed on the side surface of the vibrator unit engages with the member to be driven, so that moving force is transmitted.
