Description
Technical field
It the utility model is related to machining technology field, more particularly to a kind of smaller part radius of circle vernier measuring gage.
Background technology
In machining, it is often necessary to detect some incomplete diameter of a circles or radius on parts.Relative to complete
Diameter of a circle measures, and the measurement of incomplete diameter of a circle is relatively difficult, due in the absence of corresponding points diametrically and the center of circle not
Certainty, it is difficult to directly be measured (particularly with the small semicircle of insufficient half) using general measurer.At present, in practical application
In, incomplete diameter of a circle is by being calculated using arc height chord length method some sizes measured by general measurer mostly
Try to achieve indirectly afterwards, not only measurement error is larger, and computational methods complexity is cumbersome, it is impossible to meet quick, high in producing in enormous quantities
The requirement of accuracy detection.
Utility model content
In view of the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of small semicircle
Radius vernier measuring gage, its measuring speed is fast, need not calculate, measurement accuracy height, and has spy simple in construction, easy to use
Point, solves the radius problem that prior art can not directly, quickly and accurately measure incomplete circle.
To achieve the above object, the utility model provides a kind of smaller part radius of circle vernier measuring gage, it is characterised in that：Bag
The first ruler, the second ruler are included, described first ruler one end, second ruler one end are linked together by connector；It is described
First ruler is arranged on the first rod support by the first pressing plate, and the measuring claw of the first rod support two is respectively provided with the first roller；Institute
State the second ruler to be arranged on the second rod support by the second pressing plate, the measuring claw of the second rod support two is respectively provided with the second roller；
First roller coaxially couples with the second adjacent roller.
A kind of above-mentioned smaller part radius of circle vernier measuring gage, it is characterised in that：The first pressing plate both ends pass through the first spiral shell
Bolt is arranged on the first rod support, and the second pressing plate both ends are arranged on the second rod support by the second bolt.
A kind of above-mentioned smaller part radius of circle vernier measuring gage, it is characterised in that：It is carved with first ruler, the second ruler
Groove in units of millimeter.
A kind of above-mentioned smaller part radius of circle vernier measuring gage, it is characterised in that：It is carved with first pressing plate, the second pressing plate
Index lattice.
A kind of above-mentioned smaller part radius of circle vernier measuring gage, it is characterised in that：The connector is mandrel or bolt.
The beneficial effects of the utility model are：
Its measuring speed of the utility model is fast, need not calculate, measurement accuracy height, and with simple in construction, easy to use
The characteristics of, solve the radius problem that prior art can not directly, quickly and accurately measure incomplete circle, have very big
Economic benefit and social benefit, great popularization.
Design, concrete structure and caused technique effect of the present utility model are made furtherly below with reference to accompanying drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of as shown in figure 1, smaller part radius of circle vernier measuring gage, it is characterised in that：Including the first ruler 11, the second ruler
21, described one end of first ruler 11, the one end of the second ruler 21 are linked together by connector 6；First ruler 11 is logical
The first pressing plate 13 is crossed on the first rod support 14, described first rod support, 14 liang of measuring claws are respectively provided with the first roller 15；It is described
Second ruler 21 is arranged on the second rod support 24 by the second pressing plate 23, and described second rod support, 24 liang of measuring claws are respectively provided with second
Roller 25；First roller 15 coaxially couples with the second adjacent roller 25.
In the present embodiment, the both ends of the first pressing plate 13 are arranged on the first rod support 14 by the first bolt 12, and described the
The both ends of two pressing plate 23 are arranged on the second rod support 24 by the second bolt 22.
In the present embodiment, the groove that is carved with first ruler 11, the second ruler 21 in units of millimeter.
In embodiment, indexing lattice are carved with first pressing plate 13, the second pressing plate 23.
In the present embodiment, the connector 6 is mandrel or bolt.
Operation principle of the present utility model is：
Smaller part radius of circle vernier measuring gage of the present utility model designs according to the geometrical principle of 3 points of fixed circles.First ruler
11 one end, the one end of the second ruler 21 are linked together by connector 6.First ruler 11 is arranged on the by the first pressing plate 13
On one rod support 14, the first 14 liang of rod support measuring claw is respectively provided with the first roller 15；Second ruler 21 is installed by the second pressing plate 23
On the second rod support 24, the second 24 liang of rod support measuring claw is respectively provided with the second roller 25.First roller 15 and adjacent the
Coaxially connection is rotatable for second wheel 25.
Ruler is arranged on rod support by pressing plate, can be slid along rod support.The groove being carved with ruler in units of millimeter,
