Abstract
The utility model discloses a conversion part for measuring a central coordinate of small aperture. The conversion part adopts a ladder-shaped part comprising a detection part 14 and a positioning shaft 15, wherein the excircle of the positioning shaft 15 is in slide fit with the positioning hole of small aperture of a component to be detected; an optical detection blind hole 13 is formed in the detection part 14, and the optical detection blind hole 13 and the positioning shaft 15 are concentric; and the lower end surface of the detection part 14 is attached to the upper working surface of the component to be detected during measuring. The conversion part provided by the utility model can measure the central coordinate of small aperture precisely, thereby improving the accuracy of the mounting position, the reinspection and repair of the positioning part with small aperture in a fixture.
Description
Technical field
The utility model belongs to measuring technique, relates to a kind of instrument that the small hole size centre coordinate is measured that is used for.
Background technology
Since have cursor seat foot piece size now generally all greater than 5 millimeters, and be the integer size, so existing optical gauge is subjected to cursor seat foot piece size restrictions, can only be at measuring more than 5 millimeters and for integer aperture circular hole carries out centre coordinate.But aperture, location and installation part location is often less than 5 millimeters and be the non-integer size in anchor clamps, existing optical gauge can't be measured these aperture coordinates, and the problem that deviation appears in irregular in the anchor clamps, keeper installation site, small-bore and anchor clamps work coordinate system often takes place.
Summary of the invention
The purpose of this utility model is: provide a kind of bridgeware that can accurately measure small size or irregular aperture center coordinate, with the accuracy that improves small size or irregular aperture setting part installation site in anchor clamps and reinspection, the accuracy of reprocessing.
The technical solution of the utility model is: provide a kind of small size aperture centre coordinate to measure bridgeware, it is characterized in that, bridgeware is a ladder parts, is made up of detection piece 14 and locating shaft 15, and the path pilot hole 28 of the cylindrical of locating shaft 15 and detected member is slidingly matched; An optical detection blind hole 13 is arranged in the detection piece 14, and optical detection blind hole 13 is concentric with locating shaft 15.
The thickness deviation of described detection piece 14 is ± 0.02mm; Fit when surveying work with the work upper surface 27 of detected member 2 in the lower surface 16 of detection piece 14.
The utility model has the advantages that: can accurately measure small size aperture centre coordinate, the accuracy of improved the accuracy of keeper installation site in anchor clamps, small size aperture and reinspection, reprocessing.

Embodiment
Below the utility model is described in further details.
Referring to Fig. 1, a kind of small size aperture centre coordinate is measured bridgeware, it is characterized in that bridgeware 1 is the cylindrical shaft-type part of step, be made up of detection piece 14 and locating shaft 15, the path pilot hole 28 of the cylindrical of locating shaft 15 and detected member 2 (see figure 2)s is slidingly matched; There is an optical detection blind hole 13 at detection piece 14 centers, and optical detection blind hole 13 is concentric with locating shaft 15.
The thickness deviation of described detection piece 14 is ± 0.02mm; Fit when surveying work with the work upper surface 27 of detected member 2 in the lower surface 16 of detection piece 14.
Described detection piece 14 is a right cylinder, perhaps is the parallel polyhedron of other upper and lower surface.
Fig. 3 is a bridgeware work synoptic diagram.Principle of work of the present utility model is: the utility model bridgeware 1 is inserted in the path pilot hole 28 of detected member 2, fitted with the work upper surface 27 of detected member 2 in the lower surface 16 of the detection piece 14 of bridgeware 1, make the spigot shaft coaxle of optical detection blind hole 13 and the path pilot hole 28 of detection piece 2 of detection piece 14 upper surfaces of bridgeware 1, the centre coordinate of the centre coordinate of the path pilot hole 28 of detection piece 2 and the optical detection blind hole 13 of bridgeware 1 is the thickness of the detection piece 14 of bridgeware 1 in axial distance.As long as use optical detecting instrument to measure the centre coordinate of optical detection blind hole 13, can calculate the centre coordinate of the path pilot hole 28 of detected member 2.
