Description
Technical field
It the utility model is related to measuring device, and in particular to longitudinal annular boss diameter in the blind hole of one kind measurement workpiece longitudinal direction
Device.
Background technology
Referring to Fig. 1, there is a kind of workpiece 90 with longitudinal blind hole 93 in some mechanical equipments, in the longitudinal direction blind hole 93
The centre of bottom is equipped with the longitudinal annular boss 92 extended longitudinally upward, and the centre of longitudinal annular boss 92 leads to equipped with longitudinal register
Hole 91.In order to ensure the diameter of the longitudinal direction annular boss 92 within the scope of defined, after the process, it is necessary to the longitudinal ring
Whether the diameter of shape boss 92 measures, and judge its diameter within the scope of defined.
In general, the diameter of the longitudinal direction annular boss 92 is measured using logical only ring gauge 100 as shown in Figure 2.Referring to
Fig. 2, the logical only ring gauge 100 include ring gauge body 101 of the diameter less than the aperture of longitudinal blind hole 92 of workpiece 90, are located at ring gauge body
Longitudinally through ring gauge body 101 and the mutual go side endoporus 102 and not-go-end endoporus 103 for being located at upper and lower part respectively in 101.Go side
The micro- height for being more than longitudinal annular boss 92 of the height of endoporus 102, aperture and 92 permitted maximum gauge of longitudinal annular boss
It is equal.The highly micro- height for being more than longitudinal annular boss 92 of not-go-end endoporus 103, aperture is small to be allowed in longitudinal annular boss 92
Minimum diameter it is equal.During measurement, the go side of the logical only ring gauge of insertion, it is desirable to longitudinal ring-type of go side endoporus 102 and measured workpiece
The periphery of boss 92 is in contact, the not-go-end of the logical only ring gauge of insertion, it is desirable to not-go-end endoporus 103 not with measured workpiece longitudinal direction annular boss
92 periphery is in contact, and untill logical and not-go-end is in go side when is qualified.Technical problem present in this measuring device is：
1st, lead to only ring gauge and belong to attribute measurer, can only detect whether qualification, it is impossible to read data；
2nd, it is big by longitudinal blind hole aperture and depth limit, it is unfavorable for operating；
3rd, lead to only ring gauge to be judged whether to lead to or stopped with feeling by operator using when, subjective factor is larger；
4th, operator is not easy hardly possible by measurer by just, it is difficult to ensures measurement accuracy.
Of course, it is possible to longitudinal annular boss in the blind hole of workpiece longitudinal direction using vernier caliper or on three coordinate measuring machine
Diameter measures.But vernier caliper requires height to the deep of longitudinal blind hole, just cannot be measured more than fathoming；Three coordinates
