One kind of large-size or large tonnage cylindrical radial cylindrical workpiece measuring instrument centroid

One kind of large-size or large tonnage cylindrical radial cylindrical workpiece measuring instrument centroid, the centroid relates to a measuring device. In order to solve the conventional measuring means for detecting a complicated step, is difficult to calculate the scene, the problem of poor accuracy. Three electronic scale plate arrangement according to the invention the platform on the ground, electronic scales three plates on the same circumference, and the three flat plane of the electronic scale at the same level, is provided on each set of tooling vertical support plates electronic scale , three positioning fixture arranged on an end face of the workpiece to be measured, positioning each set of tooling and tooling correspond to the vertical support, a metal ball is mounted in the positioning tooling, positioning tooling and tooling with the vertical support, a vertical support with a metal ball and tooling positioning tooling point contact. The present invention is for a large-sized large tonnage cylindrical or cylindrical workpiece radially centroid measurement.
