Abstract
The utility model discloses an aperture gauge and relates to the field of measurement tools. The aperture gauge includes a handle and a measuring rod. The handle is connected with the measuring rod. The measuring rod is provided with cylindrical measuring heads meeting different diameter measurement standards. The measuring heads are arranged on the measuring rod linearly. The measuring heads are connected with each other in pairs. When measuring, aperture sizes can be read quickly through observing plugging depth of the aperture gauge and the precision reaches to 0.1mm. And the roundness can also be judged. The aperture gauge is reasonable in structure, convenient and practical in use and suitable for promotion and application.
Description
Technical field
The utility model relates to survey instrument, is specifically related to a kind of aperture gauge.
Background technology
The world is in development, society is improving, since the industrial revolution, machinery production is flooded with people's social production activity, from big machinery to daily screw, social productive forces have all greatly been developed, bring happiness to people, the measuring accuracy that the machinery production Operations Requirements is certain, the size of accurately measuring the stamping parts small-bore becomes its requisite part, the stamping parts small-bore is difficult to the check work that Measurement accuracy is perplexing all kinds of reviewers always, the endoporus of Φ below 4 generally measured with the inner measuring jaw of vernier caliper, but due to each one gimmick difference, same endoporus often appears measuring, different people's measurement result differences, even occur that the each measurement result of same person is not identical, and uncontrollable to aperture circularity.Application number is that CN201010513125.6 discloses a kind of hole gauge, comprises gauge barred body, drift rod and no-go gage rod, and described drift rod and no-go gage rod are fixedly mounted on respectively the two ends of described gauge barred body, adopt technique scheme, easy to use; After drift rod or no-go gage rod milling damage, only it need to be changed, the gauge barred body can continue to use, and avoids waste; Drift rod and no-go gage rod are straight barred body, are convenient to processing, and cost is low, but this hole is difficult to guarantee the accuracy of its measurement with gauge, and the circularity of endoporus also is difficult to judge with kind of calliper.
The utility model content
The purpose of this utility model is to provide a kind of aperture gauge, to solve the above-mentioned multinomial defect caused in prior art.
A kind of aperture gauge, comprise handle and sounding rod, described handle is connected with sounding rod, and described sounding rod is provided with the right cylinder gauge head of different-diameter measurement standard, described gauge head linearly is arranged on sounding rod from small to large ord, and described gauge head connects in twos by connecting link.
Preferably, be provided with the standard gauge head that diameter is 2.8mm, 2.9mm, 3.0mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.55mm, 3.6mm and 4.1mm on described gauge head.
Preferably, described handle is provided with annular knurl.
Preferably, described handle is provided with circular hole.
Preferably, described gauge head length is 3 ~ 5mm.

The utility model has the advantage of: the aperture gauge fills in the degree of depth and can read fast aperture size when measuring; can reach in precision 0.1mm; and can judge its circularity situation; the setting of annular knurl and circular hole prevents that hand from skidding, and the protection hand is to preserve from operation, and the circular hole setting is convenient to hang label; the gauge head length of 3 ~ 5mm and the sounding rod length of 4.5 ~ 5.5mm are suitable for measuring; greatly guaranteed the range of application of this utility model, decreased food is 44 ~ 46mm, is suitable for people's manual manipulation.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of aperture described in the utility model gauge.
The front view that Fig. 2 is a kind of aperture described in the utility model gauge.
Wherein: 1-handle, 2-sounding rod, 3-gauge head, 4-connecting link, 5-annular knurl, 6-circular hole.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As depicted in figs. 1 and 2, a kind of aperture gauge, comprise handle 1 and sounding rod 2, described handle 1 is connected with sounding rod 2, and described sounding rod 2 is provided with the right cylinder gauge head 3 of different-diameter measurement standard, and described gauge head 3 is arranged in a linear on sounding rod 2, described gauge head 3 connects in twos by connecting link 4, the filling in the degree of depth and can read fast aperture size of aperture gauge when measuring, can reach in precision 0.1mm, and can judge its circularity situation.
The standard gauge head that to be provided with diameter on described gauge head 3 be 2.8mm, 2.9mm, 3.0mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.55mm, 3.6mm and 4.1mm, covered the Φ 4.1 mm conventional inside diameter measurement scope related with interior household electrical appliances metal plate punching part substantially.
It should be noted that; described handle 1 is provided with annular knurl 5, and described handle 1 is provided with circular hole 6, and the setting of annular knurl and circular hole prevents that hand from skidding; the protection hand is to preserve from operation; and be convenient to hang corresponding label, described gauge head 3 length are 3 ~ 5mm, and described sounding rod 2 length are 4.5 ~ 5.5mm; the gauge head length of 3 ~ 5mm and the sounding rod length of 4.5 ~ 5.5mm are suitable for measuring; greatly guaranteed the range of application of this utility model, described handle 1 length is 44 ~ 46mm, is suitable for people's manual manipulation.
In the present embodiment, the screw that a diameter is 3.2mm as measured is taken out the tooth hole, the gauge head of gauge is stretched in the tooth hole gradually, until block in certain standard gauge head and tooth hole, can't stretch into inward again, now by the 3.2mm standard gauge head blocked, can judge that screw takes out internal diameter and the circularity in tooth hole.
Based on above-mentioned; the aperture gauge fills in the degree of depth and can read fast aperture size when measuring; can reach in precision 0.1mm; and can judge its circularity situation, and the setting of annular knurl and circular hole prevents that hand from skidding, the protection hand is to preserve from operation; the gauge head length of 3 ~ 5mm and the sounding rod length of 4.5 ~ 5.5mm are suitable for measuring; greatly guaranteed the range of application of this utility model, decreased food is 44 ~ 46mm, is suitable for people's manual manipulation.
