空金属薄板内径測定装置。 A fixed measurement pin is installed on a flat plate on which a hollow metal thin plate can be placed with a weight, and a linear bearing is used to move the pin on a linear bearing rail fixed to a base plate installed parallel to the bottom of the flat plate. A movable measuring pin is installed on a saddle that is held and movable on a straight line including the center of the fixed measuring pin, and is passed through an elongated hole provided at a position on the linear bearing rail of the flat plate to fix the fixed measuring pin. A pair of measuring pins is provided along with the measuring pin, and an optical reading scale is fixed to the side surface of the saddle in parallel with the linear bearing rail, and a weight is provided to pull the saddle with a constant force to the opposite side of the fixed measuring pin, An optical reading head is fixed on the base plate so as to face the optical reading scale so that the amount of movement of the saddle can be measured, and a hollow thin metal plate is inserted into the hollow part of the flat plate by passing both measurement pins through the hollow part thereof. A weight is placed on top of the ring so that both measuring pins can be brought into contact with the inner diameter of the hollow part using a constant force, and the distance between the measuring pins between the hollow thin metal plate to be measured and the reference ring is measured by comparing the two measuring pins. Features: A device for measuring the inner diameter of hollow metal sheets.
