Abstract
The present invention is the hollow go-no go gauge in the smart hole in metal cold working techniques, for measuring center with boss, and go-no go gauge is cavity structure, has not-go-end and go side；Not-go-end is annular groove, go side also non-annular groove；Go side nominal diameter is identical as part essence hole nominal diameter.Go side nominal diameter is identical as part essence hole nominal diameter, and tolerance is different: under it is poor be greater than difference 0.002mm under smart hole, upper difference is less than difference 0.005mm on essence hole.The present invention, can be on the lathe of processing by cleverly designing hollow go-no go gauge, and part the value for not dismantling the preceding smart hole for accurately measuring Intermediate Gray boss, not only measures scrappage that is convenient, fast but also directly reducing part.
Description
Technical field
The present invention relates to IC equipment manufacturing, and smart hole is relatively common in metal manufacture processing, and centre has the smart hole of boss
It is commonplace, it is how easy, fast and accurately to measure smart hole critically important.Disclosure sets forth the smart holes of Intermediate Gray boss
Measuring tool and method.
Background technique
In metal cold working field, it is exactly smart hole that metal, which is cold worked relatively common, and the precision overwhelming majority in smart hole exists
0.01mm-0.02mm, universal smart hole measurement have many methods, more convenient, efficiently method is using dedicated go-no go gauge
It measures, but smart hole center has boss, go-no go gauge, micrometer etc. can not all be measured, can only be carried out according to theoretical value
Processing, it is whole after processing is completed to part, it with three coordinate measuring machine, measures, the smart easily overproof (extra-deviation reason: to knife in hole
Precision, the precision of lathe, part deformation etc. smart hole can all be had an impact), it is big can only by part rejection, it is small can be with
It tries to reprocess, but is related to secondary positioning, and be smart hole, it is easy to lead to part rejection, in order to solve this problem, it is necessary to
A kind of measuring tool and application method are invented, its value can be measured on lathe, guarantees the quality and qualification rate of part.
Summary of the invention
In view of the above problems, the purpose of the present invention is designing a kind of hollow go-no go gauge, it is not only suitable in various
Between the smart hole with boss measurement, and stabilization easy to operate, real strong applicability.
It is that technical solution is that the present invention, which uses:
A kind of hollow go-no go gauge, go-no go gauge are cavity structure, have not-go-end and go side；Not-go-end is annular groove, go side
Non- annular groove；Go side nominal diameter is identical as part essence hole nominal diameter.
Go side nominal diameter is identical as part essence hole nominal diameter, and tolerance is different: under it is poor be greater than difference 0.002mm under smart hole,
Upper difference is less than difference 0.005mm on smart hole.
The go side nominal diameter of go-no go gauge is identical as smart hole nominal diameter, and tolerance is different: under it is poor be less than it is poor on smart hole
0.003mm, upper difference are greater than difference 0.001mm on smart hole.
The invention has the benefit that
1, the present invention can be on lathe, before part is not dismantled, and the side Bian Jiagong measures the smart hole of Intermediate Gray boss.
2, the present invention is at low cost, easy to operate, convenient for application and keeping.
3, the present invention can accurately measure value of portalling on lathe, greatly improve the processing efficiency and part quality of product.
4, whole design evacuation of the present invention opens the boss among smart hole, goes to detect smart hole, normal go-no go gauge is unable to measure
Centre has the smart hole of boss.
5, the present invention is easy to use, usage is simple, measurement is accurate, and the go side of hollow go-no go gauge can enter in smart hole, and not-go-end is not
It can enter in smart hole, this smart hole is qualification, this go-no go gauge makes for specific component, needs to use three-dimensional coordinates measurement after completing
Its accuracy value of machine testing, qualified rear can be used.
Detailed description of the invention
Hollow cavity schematic diagram Fig. 1 of the invention.
Fig. 2 is of the invention with part combination figure.
Fig. 3 the embodiment of the present invention schematic diagram one.
Fig. 4 the embodiment of the present invention schematic diagram two.
Specific embodiment
Invention is further described in 1-4 with reference to the accompanying drawings of the specification.
A kind of hollow go-no go gauge, go-no go gauge are 3 structure of hollow cavity, have not-go-end 1 and go side 2；Not-go-end is annular groove, go side
It also is annular groove；Go side nominal diameter is identical as part essence hole nominal diameter.
Go side nominal diameter is identical as part essence hole nominal diameter, and tolerance is different: under it is poor be greater than difference 0.002mm under smart hole,
Upper difference is less than difference 0.005mm on smart hole.
The go side nominal diameter of go-no go gauge is identical as smart hole nominal diameter, and tolerance is different: under it is poor be less than it is poor on smart hole
0.003mm, upper difference are greater than difference 0.001mm on smart hole.
A kind of application method of hollow go-no go gauge, when the go side of φ 88.88 (+0.00/-0.008) can enter in smart hole, φ
88.88 (+0.006/+0.002) not-go-end are not fashionable, as qualified.
1) drawing requirement of measured hole is pressed, vehicle corresponds to dedicated hollow go-no go gauge.The go side nominal diameter and essence of go-no go gauge
Hole nominal diameter is identical, and tolerance is different: under it is poor be greater than difference 0.002mm under smart hole, upper difference is less than poor 0.005 on essence hole, go-no go gauge
Go side nominal diameter it is identical as smart hole nominal diameter, tolerance is different: under it is poor be less than difference 0.003mm on smart hole, upper difference is greater than smart
Difference 0.001mm on hole.
2) according to hollow go-no go gauge design drawing, with three coordinate measuring machine, test measuring device uses after qualified.
3) when processing on lathe, the side Bian Jiagong is measured part with hollow go-no go gauge, constantly adjusts cutter compensation, until
The go side of go-no go gauge can enter, but not-go-end not can enter, as qualified.It arranges such as: being directed to(hole+0.005/-0.01)
Design it is as follows: when the go side of φ 88.88 (+0.00/-0.008) can enter essence hole in, φ 88.88 (+0.006/+0.002) not-go-end
It is unfashionable, it is as qualified.Dimensional units: mm.
