Abstract
The utility model discloses a kind of qualified detection means of the special internal diameter of flange, including device body, no-go gage and drift；The no-go gage is arranged on the left and right ends of device body, described device body and the position of the two no-go gage handing-over in left and right are provided with drift, two drifts are distributed in the left and right ends of the upside of device body, the distance between two drifts are consistent with flanged pipe interior diameter size to be detected, and the distance of two no-go gages in left and right is more than the size of flange bore.The no-go gage is with device body using integrated manufacture.The material of described device body, no-go gage and drift is the steel of Lip river 12.The drift is with device body using integrated manufacture.The detection means that special Temperature Treatment makes is done in the utility model Lip river 12, firm, not easy to wear and simple to operate, and error is high in 0.01mm. precisions.Detection efficiency is improved, reduces labor intensity and production cost, realizes the upgrading of e measurement technology.
Description
Technical field
A kind of measurement apparatus is the utility model is related to, the qualified detection means of specifically a kind of special internal diameter of flange.
Background technology
Flanged fitting is a kind of weld-end fittings.Because pipe fitting with pipeline for matching, so flange bore
Size should be consistent with duct size, traditional qualified detection method of flange bore is to use slide calliper rule and inside micrometer
Whether measurement minimum and maximum two dimension limit of product meets product requirement, it is necessary to which several groups of data of repeated measurement just can determine that it
Qualification, so detect easy damage survey instrument, and error is larger does not allow easy to operate, causes quality unstable, produces
Cost increase.
Utility model content
The purpose of this utility model is to provide a kind of special internal diameter of flange qualified detection means, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides following technical scheme：
A kind of qualified detection means of special internal diameter of flange, including device body, no-go gage and drift；The no-go gage is arranged on dress
The left and right ends of body are put, the position of two no-go gage handing-over of described device body and left and right is provided with drift, two drifts point
Cloth is in the left and right ends of the upside of device body, the distance between two drifts and flanged pipe interior diameter size phase one to be detected
Cause, the distance of two no-go gages in left and right is more than the size of flange bore.
As further program of the utility model：The no-go gage is with device body using integrated manufacture.
As the utility model further scheme：The material of described device body, no-go gage and drift is the steel of Lip river 12.
As the utility model further scheme：The drift is with device body using integrated manufacture.
Compared with prior art, the beneficial effects of the utility model are：Do at special temperature the utility model Lip river 12
The detection means made is managed, firm, not easy to wear and simple to operate, error is high in 0.01mm. precisions.Improve detection
Efficiency, labor intensity and production cost are reduced, realize the upgrading of e measurement technology.
Brief description of the drawings
Fig. 1 is the structural representation of the qualified detection means of the special internal diameter of flange.
In figure：1- device bodies, 2- no-go gages, 3- drifts.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of qualified detection means of special internal diameter of flange, including device sheet
Body 1, no-go gage 2 and drift 3；The no-go gage 2 is arranged on the left and right ends of device body 1, and the no-go gage 2 uses with device body 1
Integration manufacture, the position that described device body 1 joins with the no-go gage 2 of left and right two are provided with drift 3, and two drifts 3 are distributed
In the left and right ends of the upside of device body 1, the distance between two drifts 3 and flanged pipe interior diameter size phase one to be detected
Cause, drift 3 is inserted into flange pipe orifice；The distance of two no-go gages 2 in the left and right is more than the size of flange bore；With two
The distance of drift 3 is standard, and drift 3 is inserted into the hole among flanged pipe, and drift 3 can be by, and no-go gage 2 can not be by close
Lattice；The material of described device body 1, no-go gage 2 and drift 3 is the steel of Lip river 12, and the hardness of detection means is enhanced using the steel of Lip river 12,
The drift 3 is with device body 1 using integrated manufacture.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It is appreciated that other embodiment.
