ABSTRACT:
An apparatus mechanically actuates GO ring gauges and NOGO ring gauges to check whether inner and outer diameters of hollow, cylindrical-shaped products such as bushes B/G are within fit tolerances, thus automatically distinguishing between acceptable and unacceptable products. The apparatus comprises a rotatable index plate, a plurality of guide bushes G/B provided circumferentially on the index plate for receiving cylindrical-shaped products such as bushes B/G, GO ring gauges and NOGO ring gauges, respectively engaged by the end surfaces of the guide bushes and provided circumferentially of the index plate in order and secured to a body, a mechanism for discharging hollow, cylindrical-shaped products such as bushes, a pusher mechanism for pushing one end surface of a hollow, cylindrical-shaped product through the guide bush into the inner bore of the GO ring gauges and NOGO ring gauges with a predetermined pressure to judge GO and NOGO of the product, a plug gauge mechanism for pushing a plug gauge into the inner bore of a hollow, cylindrical-shaped product with a predetermined pressure for the judgement of GO and NOGO of the product, and retractable knockout pusher mechanism for pushing the pusher mechanism into the other ends of the pusher plug gauge mechanisms for the GO ring gauges, and the plug gauge mechanism for the NOGO plug gauges and for pushing the other end surface of a hollow, cylindrical-shaped product in a direction opposite to the direction of advancement of the plug gauge mechanism with a fluctuating pressure to force the product back into the guide bush.
