Description
Technical field
The utility model relates to machinofacture field of measuring technique.
Background technique
In mass production in batch, commonly using, there is fixed-size measurer to examine workpiece, and this measurer is called gauge.Work
Size on part drawing is the dimension limit for guaranteeing to have interchangeability.The gauge of measurement workpiece size is usually made two limit rulers
It is very little, i.e. maximum limit of size and the minimum limit of size.The gauge in smooth hole or axis is measured plain gauge.Plain gauge root
According to the difference for measuring interior outside dimension, it is divided to calliper and two kinds of feeler gauge.During axis processing, axle journal measurement needs are used
Calliper, if measurement is inconvenient, while measured value is inaccurate, and nothing using traditional vernier caliper measurement when measurement axle journal
Method rapid survey；The actual value of axle journal slot diameter can not be effectively measured using universal card rule.
Therefore a kind of axle journal axial trough diameter calliper is needed, for keeping the measurement of axle journal slot diameter more efficiently and accurate.
Utility model content
The purpose of this utility model is to provide a kind of axial trough diameter callipers, to solve axle journal slot diameter measurement in the prior art not
Just the problem of.
In order to achieve the above object, the base case of the utility model provides a kind of axial trough diameter calliper, including calliper ontology,
Go side and not-go-end, calliper ontology are in U-shape, and go side, not-go-end are distributed at the U-shaped opening of calliper ontology, the one side wall of U-shaped opening
On be convexly equipped with from top to bottom first while, second while, another side wall of U-shaped opening is convexly equipped with third side, first while, second while and
Third side is mutually parallel, wherein first constitutes not-go-end while with third, second constitutes go side calliper ontology while with third
Thickness is greater than the thickness of go side, not-go-end.
The beneficial effect of this base case is:
Calliper ontology is go side, the fixation of not-go-end provides brace foundation, while being provided with go side on this calliper simultaneously, stopping
End, a rule are dual-purpose, substantially increase the convenience used, operator can continue to use not-go-end after having used go side and examine
It surveys, since the thickness of calliper ontology is greater than the thickness of go side, not-go-end, this gripping for not only facilitating calliper is used, but also can
It avoids the big portion of calliper from protruding into slot, improves service efficiency.
The utility model is ingenious in design, and easy to use.
Further, go side, not-go-end bottom surface flushed with calliper ontology bottom surface.It can guarantee the structural strength of go side, not-go-end
It is higher, avoid go side, not-go-end from taking root in the middle part of calliper body thickness direction.
Further, the surface roughness of calliper ontology bottom surface, go side and not-go-end is Ra0.4.It is arranged so that this card
The use of rule is more smooth, conveniently.
Further, first while, second while between be equipped with notch.The setting of notch, cuts off between go side, not-go-end,
Facilitate the processing of every part.
Further, the material of calliper ontology, go side and not-go-end is GCr15.GCr15 refers to that a kind of alloy content is less
High-carbon-chromium bearing steel, the hardness with higher, uniform tissue, good wearability, high after quenching plus lonneal
Contact fatigue property；It can be improved the service life and stability in use of calliper.
Further, the U-shaped bottom of calliper ontology is equipped with rubber sleeve.So set, relaxing when improving people's gripping handle
Appropriateness.
Further, rubber sleeve is equipped with antiskid particles.So set, can be avoided people's hair when holding, operating calliper
Raw the phenomenon that skidding, improve operational stability.
Detailed description of the invention
Fig. 1 is a kind of main view of axial trough diameter calliper embodiment of the utility model；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is the D of Fig. 1 to partial schematic diagram.
Specific embodiment
Below by the further details of explanation of specific embodiment:
Appended drawing reference in Figure of description includes: 3, the third side 4 at 2, second of calliper ontology 1, first.
Embodiment:
As shown in Figure 1, a kind of axial trough diameter calliper, including calliper ontology, go side and not-go-end, calliper ontology are in U-shape, lead to
End, not-go-end are distributed at the U-shaped opening of calliper ontology, are convexly equipped with the first side 2, second in the one side wall of U-shaped opening from top to bottom
Side 3, another side wall of U-shaped opening are convexly equipped with third side 4, first at 2, second 3 and third side 4 it is mutually parallel, wherein
First while 2 with third while 4 constitute not-go-end, the second thickness for constituting go side calliper ontologies with when third 4 while 3 are greater than go side, not-go-end
Thickness, the axle journal slot diameter nominal dimension to be detected is 23.85 in the present embodiment0 -0.2Mm, go side width is in this implementation
23.8280 +0.008Mm, not-go-end is with a thickness of 23.65 in this implementation0 +0.008mm。
As shown in Fig. 2, calliper ontology is go side, the fixation of not-go-end provides brace foundation, while being set simultaneously on this calliper
Go side, not-go-end are set, a rule are dual-purpose, substantially increase the convenience used, operator can continue to make after having used go side
It is detected with not-go-end, since the thickness of calliper ontology is greater than the thickness of go side, not-go-end, this gripping for not only facilitating calliper makes
With, and can be avoided the big portion of calliper and protrude into slot, improve service efficiency.
As shown in figure 3, the bottom surface of go side, not-go-end is flushed with calliper ontology bottom surface.It can guarantee that go side, the structure of not-go-end are strong
Du Genggao avoids go side, not-go-end from taking root in the middle part of calliper body thickness direction.Calliper ontology bottom surface, go side and not-go-end
Surface roughness is Ra0.4.It is arranged so that the use of this calliper is more smooth, conveniently.First at 2, second 3 between set
It is jagged.The setting of notch, cuts off between go side, not-go-end, facilitates the processing of every part.Calliper ontology, go side and
The material of not-go-end is GCr15.GCr15 refers to a kind of high-carbon-chromium bearing steel that alloy content is less, by quenching plus lonneal
Hardness with higher, uniform tissue, good wearability, high contact fatigue property afterwards；It can be improved the use of calliper
Service life and stability in use.The U-shaped bottom of calliper ontology is equipped with rubber sleeve.So set, when improving people's gripping handle
Comfort level.Rubber sleeve is equipped with antiskid particles.It skids so set, can be avoided people when holding, operating calliper
The phenomenon that, improve operational stability.
Above-described is only the embodiments of the present invention, and the common sense such as well known specific structure and characteristic are herein in scheme
