In operation, the lower lifting device 2 lifts the cage upward through the first through hole 51 and enters the spherical detection device below. The holder 61 can be adjusted by the cylinder and then descend downward until each pair of chucks is held. The inner and outer sides of the side wall surface of the frame, and then the parameters of the height of the upper and lower sides of the cage are measured by the clamping action of the cylinder against the wall surface of the cage. Before testing the cage, a standard part is generally tested to calibrate the zero point of each parameter, so as to determine the qualification of the workpiece according to the difference between the workpiece produced subsequently and the zero point of the standard part.
