Abstract
The utility model belongs to the technical field of measurement, in particular to a detecting tool for center coordinates of a long circular hole. The detecting tool comprises a long circular positioning body (1), a pin shaft (2) and a detection positioning body (3), wherein a center hole passing through the upper surface and the lower surface of the long circular positioning body is formed at the center of the long circular positioning body (1); the detection positioning body (3) is a cylindrical body of which the radius is larger than the width of the long circular positioning body (1); an optical detecting hole (4) is formed at the center of the upper surface of the detection positioning body (3), and a circular hole of the same size as the center hole of the long circular positioning body (1) is formed at the center of the lower surface of the detection positioning body (3); the pin shaft (2) is matched with the two circular holes in size; and the long circular positioning body (1) is connected with the detection positioning body (3) through the pin shaft (2). Through the detecting tool, the center coordinates of the long circular hole can be detected accurately and effectively.
Description
Technical field
The utility model belongs to field of measuring technique, particularly relates to a kind of testing tool of slotted hole centre coordinate
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.Therefore, need a kind of special slotted hole centre coordinate testing tool of design.
Summary of the invention
The purpose of this utility model is:
The utility model provides a kind of testing tool that detects 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:
A kind of slotted hole centre coordinate testing tool, form by oval positioning body 1, bearing pin 2 and detection and location body 3, there is a center pit that connects upper and lower surface at the center of oval positioning body 1, detection and location body 3 is the right cylinder of radius greater than oval positioning body 1 width, there is an optical detection hole 4 at the center of its upper face, the center of lower surface has and oval positioning body 1 center pit circular hole of the same size, the size of bearing pin 2 and this two circular holes mate, and by it oval positioning body 1 are linked together with detection and location body 3.
The utility model has the advantages that:
Can precisely detect the centre coordinate of slotted hole effectively by the utility model.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model, and wherein, 1 is that oval positioning body, 2 is that bearing pin and 3 is the detection and location body.
Accompanying drawing 2 is structural representations of detection and location body 3 of the present utility model, and wherein, 4 are the optical detection hole.
Accompanying drawing 3 is structural representations of oval positioning body 1 of the present utility model.
Accompanying drawing 4 is structural representations of bearing pin 2 of the present utility model.
Embodiment
Referring to accompanying drawing 1, a kind of slotted hole centre coordinate testing tool, form by oval positioning body 1, bearing pin 2 and detection and location body 3, there is a center pit that connects upper and lower surface at the center of oval positioning body 1, detection and location body 3 is the right cylinder of diameter greater than oval positioning body 1 width, there is an optical detection hole 4 at the center of its upper face, the center of lower surface has and oval positioning body 1 center pit circular hole of the same size, the size of bearing pin 2 and this two circular holes mate, and by it oval positioning body 1 are linked together with detection and location body 3.The profile of oval positioning body 1 is identical with the hole shape of detected slotted hole, and is slidingly matched with detected slotted hole, and bearing pin 2 is slidingly matched with the center pit of oval positioning body 1, and the thickness deviation of detection and location body 3 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 body 3 top disk upper surfaces 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 body 3 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.
Claims (2)
