Abstract / Hauptanspruch
Disclosed in the present invention is a gage for measuring the distance from a hole center to a plane, consisting of a measurement plate, a fixed block, a fixed column, a spring and the like. When the gage is used, a positioning column is first inserted into a measured hole to preliminarily position the fixed column; the fixed column is further inserted downwards into the fixed column, so that the tapered surface of a tapered column is fitted with the orifice circumference of the measured hole, and the fixed column is completely positioned; whether a measured reference plane B is placed between the steps on the right side below the measurement plate is observed; and if the measured reference plane B is placed between the steps on the right side below the measurement plate, it indicates that the distance from the measured hole center to the measured reference plane B is qualified, otherwise, the distance is unqualified. The gage can measure the distance from a hole center to a plane in use, and meanwhile, has the characteristics of simple structure, high detection precision, high safety and stability, low manufacturing cost and the like.
