Abstract

The utility model relates to a go-no go gauge having a depth detection function. The go-no go gauge comprises a gauge body. One end of the gauge body extends along the axis of the gauge body, and a connecting end, a no-go gauge end and a go gauge end are sequentially and coaxially formed at the extended end of the gauge body. A radial groove is made on the periphery of the go gauge end. A go gauge and a no-go gauge are arranged at the same end, and the opening groove is made on the periphery of the go gauge, so that the hole size can be effectively detected just once for a qualification test, the depth of a hole can be effectively detected as well, and a detection process is easy and convenient, so that a conventional detection manner that the detection only can be completed with the aid of the other end or with the measuring tools being frequently replaced is prevented, and the detection efficiency is greatly improved.

Description

A kind of go-no go gauge with depth detection function

Technical field

The utility model relates to measurer field, relates in particular to a kind of go-no go gauge with depth detection function.

Background technology

Go-no go gauge is a kind of of measurer, if adopt metering measurer (as vernier caliper, milscale etc. is with graduated measurer) comparatively time-consuming bothersome for typical products in mass production.At present, the go-no go gauge of using is generally all the two ends that drift and no-go gage are placed in respectively connecting rod, during test, after needing one end to measure, change the other end and measure, waste time and energy, and when measuring hole depth, the measurer that need to more renew is measured, and detection efficiency reduces greatly.

Utility model content

The applicant is for above-mentioned existing issue, be studied improvement, provide a kind of simple in structure, measure the easy go-no go gauge with depth detection function, effectively realized the qualified disposable measurement in aperture, there is hole depth measuring ability simultaneously, greatly improved detection efficiency.

The technical scheme that the utility model adopts is as follows:

A go-no go gauge with depth detection function, comprises regulator, and one end of regulator axially extends to form coaxial link, no-go gage end and drift end successively along regulator, is positioned in the periphery of described drift end and has radial groove.

Its further technical scheme is:

The diameter of drift end is less than the diameter of no-go gage end;

Drift end and no-go gage end are integrally connected formation cylindrical cone;

Groove is connected and composed by bottom surface, the first side and the second side, and described the first side and bottom surface are positioned on drift end, and described the second side is positioned on no-go gage end;

The periphery of link caves inward and forms annular inner concave;

The one end that is positioned at described drift end also arranges the first chamfering, and the one end that is positioned at regulator also arranges the second chamfering;

Distance L between the second side of described groove and the end face of drift end and the deep equality of tested hole depth.

The beneficial effects of the utility model are as follows:

Drift and no-go gage are arranged at same one end, periphery at drift arranges open slot simultaneously, not only effectively realized the qualified disposable measurement in aperture, also effectively realized the detection to hole depth, have suffered testing process simple and convenient, avoid needing frequently to change measurer in the past or commutate into the other end to detect, greatly improved detection efficiency.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

As shown in Figure 1 and Figure 2, the utility model comprises regulator 4, and one end of regulator 4 is along axial coaxial link 3, no-go gage end 2 and the drift end 1 of extending to form successively of regulator 4, and the periphery of link 3 caves inward and forms annular inner concave.The diameter of drift end 1 is less than the diameter of no-go gage end 2, and drift end 1 is integrally connected formation cylindrical cone with no-go gage end 2.As shown in Figure 3, be positioned in the periphery of drift end 1 and have radial groove 101.Groove 101 is connected and composed by bottom surface 1012, the first side 1011 and the second side 1013, and described the first side 1011 and bottom surface 1012 are positioned on drift end 1, and described the second side 1013 is positioned on no-go gage end 2.The one end that is positioned at drift end also arranges the first chamfering 102, and the one end that is positioned at regulator 4 also arranges the second chamfering 401.The second side 1013 of groove 101 and the distance L between the end face of drift end 1 and the deep equality of measured hole.

Specific works process of the present utility model is as follows:

Operating personnel are by hand-held regulator 4, the endoporus that drift end 1 is placed in to test product is inner, if drift end 1 cannot pass through this product endoporus, represents that aperture is less than normal, if can pass through, represent that aperture is qualified, then continue hand-held regulator 4, make the endoporus of no-go gage end 2 contact products, if no-go gage end 2 can pass through, illustrate that aperture is bigger than normal, if cannot pass through, represent that aperture is qualified.When whether measurement products hole depth is qualified, only drift end 1 of the present utility model need to be placed in to product endoporus, drift end 1 continues to stretch in product endoporus until the second side 1013 of spot face and groove 101 in same level, represents that this product hole depth has reached requirement.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and without prejudice to basic structure of the present utility model in the situation that, the utility model can be done any type of modification.
