instrument for measuring taper

The utility model relates to an instrument for measuring taper. The utility model is a measuring instrument for measuring the taper of the inner cone and the taper of the outer cone of mechanical processing industries. The utility model is composed of a composite bracket, a supporting roller, a sliding block, a measuring roller and a measuring frame. The utility model has the advantages of small size, light weight, convenient use, strong universality and high detecting precision. The utility model is used for the final detecting of the inner cone and the outer cone, and the utility model is used for the detecting of the cone processing process. The utility model does not need to be matched with high-precision platforms.
