Abstract
The utility model relates to a transformation part used for measuring the center coordinate of an oblong hole, which belongs to a measuring technique. The transformation part is characterized in that a detection positioning shaft (1), an oblong positioning body (2) and a nut (3) are included, wherein the oblong positioning body (2) is in sliding fit with the oblong hole to be measured, and a center hole penetrating through an upper surface and a lower surface is arranged in the center of the oblong positioning body (2); a thread section at the lower end of the detection positioning shaft (1) penetrates through the center hole of the oblong positioning body (2) and is engaged with the nut (3), and an optical detection blind hole is arranged in the center of the upper surface of a disk at the upper part of the detection positioning shaft (1). The utility model can accurately measure the center coordinate of the oblong hole and improves the accuracy of a oblong hole positioning part in a mounting position of a clamp and the accuracy of redetection and repair.
Description
Technical field
The utility model belongs to measuring technique, relates to a kind of bridgeware that the slotted hole centre coordinate is measured that is used for.
Background technology
Existing optics installs instruments and can only carry out the centre coordinate measurement at circular hole.But in anchor clamps, often adopt the slotted hole localization method during location and installation part.Owing to can't measure the slotted hole centre coordinate, the problem that deviation appears in slotted hole keeper position location and anchor clamps work coordinate system in the anchor clamps often takes place.
Summary of the invention
The purpose of this utility model is: provide a kind of bridgeware that can accurately measure the slotted hole centre coordinate, with the accuracy that improves slotted hole keeper installation site in anchor clamps and reinspection, the accuracy of reprocessing.
The technical solution of the utility model is: be used for the bridgeware that the slotted hole centre coordinate is measured, it is characterized in that it is made up of detection and location axle 1, oval positioning body 2 and nut 3; The profile of oval positioning body 2 is identical with the hole shape of detected slotted hole, and is slidingly matched with detected slotted hole, and a center pit that connects upper and lower surface is arranged at the center of oval positioning body 2; Detection and location axle 1 is connected to form by top disk and bottom locating shaft, the lower surface center of the upper end of locating shaft and disk is connected to integral body, there is screw thread the lower end of locating shaft, the thread segment of locating shaft lower end passes behind the center pit of oval positioning body 2 and nut 3 engagements, the center pit of locating shaft and oval positioning body 2 is slidingly matched, the diameter of detection and location axle 1 top disk has an optical detection blind hole greater than the width of oval positioning body 2 at the center of detection and location axle 1 top disk upper surface; The thickness deviation of detection and location axle 1 top disk is not more than 0.02mm.
The utility model has the advantages that: can accurately measure the slotted hole centre coordinate, the accuracy of improved the accuracy of slotted hole keeper installation site in anchor clamps and reinspection, reprocessing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below the utility model is described in further details.Referring to Fig. 1, be used for the bridgeware that the slotted hole centre coordinate is measured, it is characterized in that it is made up of detection and location axle 1, oval positioning body 2 and nut 3; The profile of oval positioning body 2 is identical with the hole shape of detected slotted hole, and is slidingly matched with detected slotted hole, and a center pit that connects upper and lower surface is arranged at the center of oval positioning body 2; Detection and location axle 1 is connected to form by top disk and bottom locating shaft, the lower surface center of the upper end of locating shaft and disk is connected to integral body, there is screw thread the lower end of locating shaft, the thread segment of locating shaft lower end passes behind the center pit of oval positioning body 2 and nut 3 engagements, the center pit of locating shaft and oval positioning body 2 is slidingly matched, the diameter of detection and location axle 1 top disk has an optical detection blind hole greater than the width of oval positioning body 2 at the center of detection and location axle 1 top disk upper surface; The thickness deviation of detection and location axle 1 top disk is not more than 0.02mm.
Principle of work of the present utility model is: after the utility model is inserted measured slotted hole, the optical detection blind hole of detection and location axle 1 top disk upper surface and the spigot shaft coaxle of measured slotted hole, the centre coordinate of the centre coordinate of measured slotted hole and optical detection blind hole are the thickness of detection and location axle 1 top disk in axial distance.As long as use optical detecting instrument to measure the centre coordinate of optical detection blind hole, can calculate the centre coordinate of measured slotted hole.
