Description
Technical Field
The utility model relates to an kinds of measuring tools especially relate to kind of interior circular arc measuring tool, the utility model discloses specially adapted does not link up the measuring tool of interior circular arc.
Background
At present, the diameter size of the inner arc is generally measured by a vernier caliper, however, for example, the inner arcs of the guide ribs of the inner cavities of the cylinder body of the internal combustion engine, the cylinder body of the steam turbine, the valve body and the like, the inner arcs of the stator of the motor are all discontinuous inner arcs, and for the diameter of the inner arc with odd number of the guide ribs, the existing vernier caliper cannot measure the inner diameter size, namely, the vernier caliper cannot measure the inner diameter formed by the inner arcs with odd number of sections uniformly distributed on circumferences.
Disclosure of Invention
The utility model aims at the shortcoming that prior art exists, provide special measuring tools of interior circular arc that do not intersect that can measure the interior circular diameter that the inner circle diameter of circle is constituteed in evenly distributed odd number section on circumference.
The technical scheme of the utility model including base and measuring device, characterized by base is disc, and even system has a plurality of radial guide ways in this disc plane, and centre of a circle department has the regulation hole, and measuring device includes thimble, calibrated scale, regulation double-screw bolt, adjusting nut, and the thimble moves the cooperation and installs in the radial guide way, and the calibrated scale is installed in the radial guide way of thimble upside, and the plane is equipped with the scale display device who mutually supports with the calibrated scale on the thimble upper plane, and regulation double-screw bolt moves the cooperation and installs in the regulation hole, and its lower terminal surface has radial convex shoulder, and the circumferencial direction system has the axial groove that equals with the radial guide way in the disc quantity width, and the tank bottom of this axial groove is the inclined plane, and thimble medial extremity portion has the inclined plane that mutually supports with the inclined plane on the regulation double-screw bolt, and thimble lower plane middle part has the lower step, and the radial guide way tank bottom outside this lower step has the upper step the spring is installed.
In the above technical scheme, three radial guide grooves are uniformly formed in the circular plane of the disc.
In the above technical scheme, five radial guide grooves are uniformly formed in the circular plane of the disc.
Compared with the prior art, the utility model beneficial effect realize measuring the interior circle diameter of forming the arc in the odd number section.
