Description
Technical field
Field of machining of the present invention, more particularly to the size precision testing technology in hole.
Background technique
For the inner hole part of batch production, mechanical processing industry and aircraft manufacturing industry etc. generally use the special of go-no go gauge
It is checked with measurer, comparison has the characteristics that high-efficient, speed is fast using the general measurer of inside micrometer.
When currently used aperture go-no go gauge is examined, as shown in Figure 1, to qualified hole, one end drift m of aperture go-no go gauge
Should can through hole, the one end no-go gage n is unable to through hole.But as shown in Fig. 2, when hole h occurs oval overproof, aperture go-no go gauge
The one end drift m can with through hole p, one end no-go gage n of aperture go-no go gauge can not through hole h, hole h qualification can be mistaken as；
Oval overproof substandard product is delivered as qualified products, causes hidden danger of quality.Check that the ellipse to portal is overproof
Such case typically now uses dial bore gage, and measurement is relatively cumbersome, needs the long period compared to the inspection of aperture go-no go gauge,
It is not able to satisfy the inspection demand of a large amount of parts.
Summary of the invention
The present invention creatively proposes a kind of novel internal diameter go-no go gauge, by the redesign to go-no go gauge, to overproof
Inner hole is fast and accurately detected, to meet engineering design requirements.
Technical solution of the present invention, a kind of internal diameter go-no go gauge, one end are drift, and drift is identical as common drift, the other end
For no-go gage, which is characterized in that the side of no-go gage includes two parts cylindrical surface and the face a, the face b, the face c and the face d, the face e and 6, the face f
Plane, wherein two parts cylindrical surface diameter is identical as common no-go gage diameter and central symmetry, and the face c is parallel with the face d and left and right
Symmetrically；The face a and the face b bilateral symmetry and angle are the face α, e and the face f bilateral symmetry；The face a and the face e bilateral symmetry；The face b and the face f
Symmetrically；The both ends in the face c and the face d are on cylindrical surface identical with drift diameter.
The face c of the no-go gage and the distance in the face d are the 0.6 ~ 0.9 of not-go-end cylindrical surface diameter.
The angle α, α ∈ [80 °, 100 °], angle tolerance ± 2 °.
The present invention can quickly check that the oval overproof situation of internal diameter, method are simple and efficient.

Fig. 2 is that common go-no go gauge examines elliptical aperture schematic diagram
Fig. 3 is go-no go gauge schematic diagram of the invention
Fig. 4 is that go-no go gauge of the invention examines elliptical aperture schematic diagram.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
See Fig. 3 to Fig. 4, a kind of internal diameter go-no go gauge of the invention, one end is drift m, and drift is identical as common drift, one end
No-go gage n, which is characterized in that the side of no-go gage includes that two parts cylindrical surface and the face a, the face b, the face c and the face d, the face e and 6, the face f are flat
Face, wherein two parts cylindrical surface diameter is identical as common no-go gage diameter and central symmetry, and the face c is parallel with the face d and left and right pair
Claim, the distance in the face c and the face d is the 4/5 of not-go-end cylindrical surface diameter；The angle in the face a and the face b is 80 ° and bilateral symmetry；The face e and f
The angle in face is 80 ° and bilateral symmetry.The face a and the face e bilateral symmetry；The face b and the face f bilateral symmetry.
Drift m when in use, is first rotatably inserted into hole h and passed through by a kind of internal diameter go-no go gauge of the invention；No-go gage n is tasted again
Examination be rotatably inserted into hole h, if no-go gage can through hole h, no-go gage check it is unqualified；If rotating angle, no-go gage n cannot pass through
Hole then illustrates no-go gage passed examination.
