Abstract
The utility model relates to the technical field of measuring instruments, in particular to a vernier with conical legs, which is particularly suitable for measuring distance between the centers of two sample punch holes. The vernier with the conical legs comprises two major parts, i.e. a main scale (1) and a vernier (2). The legs of the main scale (1) and the vernier (2) are conical. Since the two legs of the main scale (1) and the vernier (2 are fit with the sample punch holes, the measurement accuracy can be greatly improved, the measurement accuracy of the vernier with the conical legs is high, the vernier with the conical legs is convenient to use, the readings are simple and clear, and the requirement of high-accuracy measurement can be well met.
Description
Affiliated technical field
The utility model relates to the measurer technical field, is specially adapted to measure the cone pin vernier scale of distance between the different dotting punch center.
Background technology
In the commercial production, often run into the problem that needs to measure distance between the different dotting punch center.As in the tension test of metal material, sample is stamped the sample dotting punch before stretching, measures the distance between the different dotting punch, measures the distance between these two sample dotting punches then after breaking again, and the difference of two measured values is the elongation of metal material.Because be subjected to the restriction of existing vernier caliper pawl pin shape, the summit of vernier caliper pawl pin can't overlap fully with sample dotting punch center, measured value exists bigger error, can't satisfy the demand of high precision tension test.
The utility model content
In order to overcome the low deficiency of range accuracy between the different dotting punch of existing vernier caliper measurement, the utility model provides a kind of cone pin vernier scale, and this cone pin vernier scale measuring accuracy height, reading are directly perceived, simple to operate.
The technical scheme that its technical matters that solves the utility model adopts is: this cone pin vernier scale is the improvement (see figure 1) of vernier caliper, and it comprises main scale, vernier scale.Vernier scale can slide along main scale, the pawl foot portion of main scale and vernier scale is a size, the identical cone of shape, line between the two pawl foot portion cone summits is parallel with the glide direction of vernier scale, and the distance between the two pawl foot portion cone summits is the metering reading of this cone pin vernier scale.Because cone pin vernier scale two pawl foot portions are cone, and the shape of sample dotting punch also is a cone, measure between the different dotting punch of (see figure 2) apart from the time cone pin vernier scale two pawl foot portions cone can coincide with the sample dotting punch well, two pawl foot portion cone summits overlap with sample dotting punch center fully, thereby have improved measuring accuracy greatly.
The beneficial effects of the utility model are, cone pin vernier scale measuring accuracy height, easy to use, reading is simple and clear.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model cone pin vernier scale front view, partial enlarged drawing I, M-M cut-open view, N-N cut-open view.
Fig. 2 is that the utility model cone pin vernier scale is implemented illustration, partial enlarged drawing II, D-D cut-open view.
1. main scales among the figure, 2. vernier scale, 3. metal stretching sample.
2 of A, B are respectively main scale (1) and vernier scale (2) pawl foot portion cone summit, and the C point is the central point of the sample dotting punch on the metal stretching sample (3).
Embodiment
In Fig. 1, this cone pin vernier scale comprises main scale (1), vernier scale (2).Vernier scale (2) can slide along main scale (1), the pawl foot portion of main scale (1) and vernier scale (2) is a size, the identical cone of shape, line between the two pawl foot portion cone summits (A point and B point) is parallel with the glide direction of vernier scale (2), and the distance between two pawl foot portion cone summits (A point and B point) is the metering reading of this cone pin vernier scale.Partial enlarged drawing I from figure, M-M cut-open view, N-N cut-open view the pawl foot portion of main scale (1) and vernier scale (2) as can be seen are a size, the identical cone of shape.
In embodiment illustrated in fig. 2, when between the different dotting punch of measuring metal stretching sample (3) apart from the time, cone pin vernier scale is placed on the sample dotting punch of metal stretching sample (3), make the sample dotting punch of two pawl foot portion complete contacting metal tensile samples of cone (3) of main scale (1) and vernier scale (2), because cone pin vernier scale two pawl foot portions are cone, and the shape of sample dotting punch also is a cone, the two can coincide well, two pawl foot portion cone summits (A point and B point) overlap with sample dotting punch center (C point) fully, distance between two pawl foot portion cone summits (A point and B point) is the metering reading of this cone pin vernier scale again, and what directly read is exactly distance between the different dotting punch so need not convert.Partial enlarged drawing II from figure two pawl foot portion cone summits (A point and B point) as can be seen overlaps fully with the center (C point) of sample dotting punch.
Claims (1)
1. cone pin vernier scale of measuring distance between the different dotting punch center, comprise that main scale (1), vernier scale (2) is characterized in that vernier scale (2) can slide along main scale (1), the pawl foot portion of main scale (1) and vernier scale (2) is a size, the identical cone of shape, line between 2 pawl foot portion cone summit A points and the B point is parallel with the glide direction of vernier scale (2), and the distance between 2 pawl foot portion cone summit A points and the B point is the metering reading of this cone pin vernier scale.
