  • Patent number: 5345675
    Abstract: A pair of second cameras mounted on a robot are located in front of, and symmetrically with respect to the center of a wheel hub of a vehicle, according to approximate coordinates of the center of the wheel hub calculated from an image of the wheel hub taken by a first camera. Revised coordinates of the center of the wheel hub, a rotational displacement from a standard rotational position of the wheel hub, and a turning angle of the wheel hub toward the right or left with respect to a progressive direction of the vehicle are calculated from the images obtained by the second cameras. A wheel is then automatically mounted to the wheel hub by the robot, according to the results of calculation.

  • Patent number: 4794690
    Abstract: A phase adjusting apparatus for use in an assembling machine for assembling first and second workpieces including a movable frame which is arranged to move into and out of the space formed between the two workpieces. Prior to coupling the two workpieces, the movable frame is moved to enter the space and a first movable table and a second movable table on the movable frame are used to adjust the phase of a rotary body on the first workpiece and the phase of a rotary shaft on the second workpiece to another. After removing the movable frame from the space, the two workpieces are then brought together so that the rotary body and the rotary shaft are coupled to each other.

  • Patent number: 4542576
    Abstract: A fastening apparatus which includes a supporting column with a working station installed on one side at the lower end thereof. Upper and lower annular rails are supported on and coaxially surround the upper portion of the column with a portion of the annular rails being vertically movable. Plural multi-spindle fastening heads are supported on the rails and movable circularly there around. An indexing device is mounted on the upper portion of the column for selectively engaging in moving a desired one of the heads to a position above the working station where the vertically movable portion of the annular rails is provided. A connecting head supported by the upper portion of the column is engageable with the fastening head that is positioned over the working station for supplying power thereto from a separate power source. The movable portion of the annular rails raises and lowers the selected fastening head to perform the fastening operations on the work piece at the working station.
