[0029] Example: see figure 1 , a device for simultaneously measuring the size and roundness of tiny circular holes, comprising a He-Ne laser 1, a circular hole to be measured and a holder 2, a frosted glass receiving screen with a mark 3, an information collection device 4, and an information processing device 5,
[0030] Among them, the He-Ne laser 1, the circular hole to be measured and the holder 2, the glass receiving screen 3 with the logo and the information collection device 4 are carried by the two-dimensional adjustable device and placed on the optical platform, in which the tiny circle to be measured is clamped. The hole is a precision two-dimensional adjustable device, through adjustment to ensure that their optical axis (or center) is basically on a straight line, the surface of the measured round hole, the holder and the glass receiving screen with the mark are parallel and perpendicular to the above-mentioned straight line, the data Through precise adjustment and...
