Claims

[Claims for Utility Model Registration] An automatic positioning device for a road wheel for automatically determining the processing position of a wheel having ribs formed around the processing area, which grips the wheel placed on a conveyor. a wheel gripping section for rotating the wheel; a wheel rotation section that rotationally displaces a plane including the processing portion of the wheel based on a gripping end signal from the wheel gripping portion; and a sensor oriented toward the plane including the processing portion of the wheel. a rotational positioning stopper which moves upward when the tip of the sensor comes into contact with a rib of the wheel and maintains that position when the tip of the sensor avoids the rib; and a torque motor that detects the torque and stops the operation of the wheel rotation part when a sensor of the stopper comes into contact with a side surface of the rib to prevent rotation of the wheel. Automatic positioning device.
