Abstract
The utility model discloses a kind of go-no go gauges for having taper hole checking function, including cylinder type body, logical only test section are formed in the middle part of ontology, front end forms circular platform type taper hole test section；It is logical only spaced apart between test section and taper hole test section；Taper hole test section is bigger diameter end close to one end of logical only test section；Taper hole test section bigger diameter end forms semicircular indentations.The utility model designs the special construction of go-no go gauge, it is made to have the function of taper hole relative dimensions coarse verification, realizes the entry detectability of go-no go gauge, in the high-volume of enterprise continuously examines operation, can significantly improve checkability；The design of go-no go gauge part can realize the inspection in endoporus aperture；Taper hole detection part by the centrum of reasonable design size and tolerance, can realize the coarse verification of taper hole size；Epicentral notch design improves accuracy and the convenience of inspection.
Description
Technical field
The utility model belongs to a kind of geometric measurement, and in particular to a kind of go-no go gauge for having taper hole checking function.
Background technology
In Machine Design, endoporus connection taper hole is a kind of general design, and structure is as shown in Figure 1.Endoporus aperture and cone
Hole taper, the detection method of depth are more, and in the case where enterprise's batch is examined, to pursue checkability, aperture is often with logical
No-go gage is examined, and the coarse verification of taper hole size is realized often through special gauge.It is multiple due to needing to examine in practice examining
Project needs frequently to replace trier in checkout procedure, influences operating efficiency.
Utility model content
The utility model proposes that the purpose is to provide one kind to have in order to overcome shortcoming in the prior art
The go-no go gauge of taper hole checking function.
The technical solution of the utility model is：
A kind of go-no go gauge for having taper hole checking function, the go-no go gauge include cylinder type body, are formed in the middle part of ontology logical
Only test section, front end form circular platform type taper hole test section；It is logical only spaced apart between test section and taper hole test section；Taper hole
Test section is bigger diameter end close to one end of logical only test section；Taper hole test section bigger diameter end forms semicircular indentations.
Logical only test section, taper hole test section and the ontology are coaxial.
The outer diameter of the logical only test section is more than ontology, and the half of the length of body length is to 2/3rds.
The taper hole test section bigger diameter end outer diameter is no more than logical only test section outer diameter, miner diameter end outer diameter and body diameter phase
Together.
The both ends of the logical only test section form circular conical surface.
The outer circumferential of the logical only test section is into hatching knurling.
The beneficial effects of the utility model are：
The utility model designs the special construction of go-no go gauge, it is made to have the work(of taper hole relative dimensions coarse verification
Can, the entry detectability of go-no go gauge is realized, in the high-volume of enterprise continuously examines operation, inspection can be significantly improved
Efficiency；The design of go-no go gauge part can realize the inspection in endoporus aperture；Taper hole detection part passes through reasonable design size and public affairs
The centrum of difference can realize the coarse verification of taper hole size；The design of epicentral notch improves the accuracy of inspection and convenient
Property.
Description of the drawings
Fig. 1 is the partial structural diagram that the utility model treats workpiece for measurement；
Fig. 2 is the front view of the utility model；
Fig. 3 is the left view of the utility model.
Wherein：
The logical only test section of 1 ontology 2
3 taper hole test section, 4 notch
5 taper hole, 6 endoporus.
Specific embodiment
With reference to the accompanying drawings of the specification and the embodiment go-no go gauge for having taper hole checking function a kind of to the utility model into
Row is described in detail：
As shown in Figure 2,3, a kind of go-no go gauge for having taper hole checking function, the go-no go gauge include cylinder type body 1, this
1 middle part of body forms logical only test section 2, and front end forms circular platform type taper hole test section 3；It is logical to stop between test section 2 and taper hole test section 3
It is spaced apart；Taper hole test section 3 is bigger diameter end close to one end of logical only test section 2；3 bigger diameter end of taper hole test section forms half
Circumferential notch 4.
Logical only test section 2, taper hole test section 3 and the ontology 1 are coaxial.
The outer diameter of the logical only test section 2 is more than ontology 1, and the half of 1 length of the length of ontology to three/
Two.
The 3 bigger diameter end outer diameter of taper hole test section is no more than logical only 2 outer diameter of test section, miner diameter end outer diameter and 1 outer diameter of ontology
It is identical.
The both ends of the logical only test section 2 form circular conical surface.
The outer circumferential of the logical only test section 2 is into hatching knurling.
The logical only test section 2 is go side close to one end of taper hole test section 3, and the other end is not-go-end.
The application method of the utility model：
The endoporus 6 of workpiece for measurement is first examined with the go side of logical only test section 2, if as shown in Figure 1, cannot pass through, it is interior
Diameter dimension overproof, judgement workpiece for measurement are unqualified.
It, can be by further with the relative dimensions of 3 coarse verification taper hole 5 of taper hole test section, during inspection if can pass through
Circumferential notch 4 on taper hole test section 3 observes taper hole test section 3 and the compatible degree of taper hole is sentenced with carrying out the qualification of taper hole meter
It is fixed.
Such as taper hole size qualification, then the endoporus 6 of the not-go-end inspection workpiece for measurement with logical only test section 2, if it is possible to pass through
Then 6 dimension overproof of endoporus, judgement workpiece for measurement it is unqualified, if cannot can determine that if workpiece for measurement qualification.
In this way, the inspection of sizes only can be realized with a kind of this cubing, it can be thick while examining endoporus go side size
The relative dimensions of taper hole are slightly examined, batch is not required to frequently replace cubing when examining, and substantially increases the efficiency of inspection.
