Abstract
The utility model relates to a measuring tool for measuring the depths of scratches on the surfaces of a negative sphere and a positive sphere and is aimed at providing a measuring tool for measuring the depths of scratches on the surfaces of a negative sphere and a positive sphere with an orthogonal measuring method. The measuring tool comprises a measuring rod, a measuring pedestal, and a fastening screw. The measuring pedestal is a concave cylinder with an opening on the bottom thereof and is equipped with an axial circular center hole. A dial indicator measuring rod passes through the axial circular center hole to be installed on the measuring pedestal. A radial threaded hole is disposed from the side of the cylinder of the measuring pedestal to the axial circular center hole. The fastening screw is installed inside the radial threaded hole. The measuring tool has characteristics of simple structure, easy manipulation, high measuring efficiency and precision, and easy production.
Description
Technical field
The utility model relates to a kind of measurer, particularly a kind of measurer of measuring cloudy ball, the measurement of positive spherome surface scratch depth.
Background technology
When tested entity is plane, utilize the scratch depth of the measuring method measurement entity of quadrature to be not difficult to realize, but how to realize orthogonal measuring for the scratch depth of sphere, routine measurement instrument is difficult to realize.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of measurer that can adopt orthogonal measuring method to measure cloudy ball, positive spherome surface scratch depth.
For solving the technical matters existing, the technical solution adopted in the utility model is, the measurer of measuring cloudy ball, positive spherome surface scratch depth comprises sounding rod, measures pedestal, holding screw, described pedestal is the spill cylinder of bottom opening, measure pedestal and be provided with axial circle center hole, sounding rod is arranged on and measures on pedestal through axial circle center hole, measures that radial screw bore is opened on top, pedestal cylindrical shell side until axial circle center hole, and holding screw is arranged in radial screw bore.Described sounding rod adopts dial gauge or scale or vernier caliper or rotation milscale, according to measuring accuracy, selects, and for improving measuring accuracy, described sounding rod bottom is cone.
When base bottom surface contacts calibration during sphere with sounding rod, base bottom surface with measure contact point in same cambered surface, and base bottom surface with measure cambered surface that contact point forms and calibrate the same cambered surface of sphere; During sounding rod bottom surface contact calibration sphere, the contact point of sounding rod bottom surface is in same cambered surface, the same cambered surface that the cambered surface that the contact point of sounding rod bottom surface and calibration sphere forms and the contact point of base bottom surface and calibration sphere form, and sounding rod bottom surface axial line overlaps with the planar central vertical line that the contact point of calibration sphere forms with pedestal vertical line and base bottom surface.
The beneficial effects of the utility model: it is poor that the measuring principle that the utility model has been quoted gear transmission is directly measured the scratch depth of sphere, solved the measurement difficult problem about sphere scratch depth, solved the measuring method of quadrature in any situation of sphere scratch depth, by the measurement of 3 D complex shape, be reduced to the direct measurement of bidimensional, this utility model is simple in structure simultaneously, easy to operate, measures efficiency and precision high.
