End face runout amount measuring tool

The utility model discloses an end face runout amount measuring tool comprising a positioning rod, wherein the upper end of the positioning rod is provided with a clamping device, lever meters are clamped on the clamping device, the measuring rods of the lever meters are perpendicular to an end face to be measured, and the positioning rod matches a guide tube hole in diameter. When the end face runout amount measuring tool is used, a work piece to be measured is placed on a measurement platform, a matching and suitable positioning rod is placed in the guide tube hole of the work piece, and therefore the positioning rod can well contact with the guide tube hole and a positioning gap can be reduced, the bottom end of a screw stud can contact with the platform, and whether the measuring head of one lever meter contacts with an end face of the work piece can be checked. After the lever meter is set to zero and is swiveled once, a data difference value which appears on the lever meter is the numerical value of the
