Measuring instrument for measuring position degree of holes with pattern draft

The utility model provides a measuring instrument for measuring position degree of holes with pattern draft, comprising a measuring instrument base which has the same shape with the end surface of a product; the measuring instrument base is provided with three positioning taper pins; the measuring instrument base is provided with a plurality of holes which correspond to the end surface holes of the product; the holes are internally provided with measuring sleeves which are internally provided with measuring rods; measuring heads designed according to the aperture dimension and the comprehensive tolerance are arranged in front of the measuring rods, wherein the holes for fixing the measuring sleeves on the base, the measuring sleeves, the measuring rods and the measuring heads have the same concentricity; the holes for fixing the measuring sleeves on the base are in interference fit with the measuring sleeves; and the measuring sleeves are in clearance fit with the guide parts of the measuring rods. When in use, the positioning taper pins are used for positioning the end surfaces; the position degree of the product can be measured directly after the measuring rods are inserted in the measuring sleeves; the measuring rods can ensure the position degree of the holes within the depth range of the holes; and compared with the general three-coordinate measuring way, the measuring result is more reliable, the measuring time for complete measurement is only 1 to 3 minutes, the time is shortened greatly, and the resource waste is reduced.
