Description
Technical Field
The utility model relates to a length measuring tool, in particular to a vernier caliper for same-side abutting measurement.
Background
The vernier caliper is a common instrument for measuring length in industry and consists of a main scale and a vernier scale assembled on the main scale and sliding. The ruler body and the vernier are both provided with measuring claws, and the measuring claws of the ruler body and the vernier are abutted against a measuring object, so that the structural size of the object can be measured. Such as measuring the outside and inside diameters of the tube and measuring the width of the groove.
The current problem is that the two measuring jaws provided on the existing vernier caliper are usually opposite or opposite in orientation, and this arrangement enables the measurement of conventional structural dimensions, such as the outer diameter and the inner diameter of the measuring tube and the width of the measuring groove, as described above, but for some special structures it is cumbersome to measure the dimensions with conventional vernier calipers.
For example, if the center distance between two bolt holes with bolts is to be measured, it cannot be directly measured, but the distance between the outer side or the inner side of the bolt and the nut can be measured by using a vernier caliper, and then the center distance between the two bolt holes can be obtained by dimension conversion, which is very inconvenient.
Disclosure of Invention
The utility model aims to provide a vernier caliper for same-side abutting measurement, and two measuring claws of the vernier caliper can respectively abut against the same sides of two targets to measure the size.
In order to achieve the technical purpose, the utility model adopts the following technical scheme:
the vernier caliper comprises a main scale, a vernier scale, a fixed measuring claw and a swimming measuring claw; the fixed measuring claw is fixed at the zero scale end of the main scale, the measuring edge of the fixed measuring claw faces the tail end of the main scale, the vernier is assembled on the main scale, and the floating measuring claw is fixed on the vernier; the orientation of the measuring edge of the floating measuring claw is consistent with the orientation of the measuring edge of the fixed measuring claw.
Further, when the vernier is at the zero reference position, the measuring edge of the fixed measuring claw and the measuring edge of the free measuring claw are on the same plane.
Further, the play measuring claw is located at the back of the main scale.
Compared with the prior art, the vernier caliper has the beneficial effects that: the two measuring claws in the vernier caliper, namely the fixed measuring claw and the movable measuring claw, are oriented in the same direction at the measuring edges, so that when the vernier caliper is used for measuring, the two measuring claws of the vernier caliper respectively lean against the same side of two targets to measure the size, and the size measurement of a special structure, such as the center distance between two bolt holes with bolts, can be realized.

Detailed Description
The utility model is further illustrated by the following specific examples:
the present embodiment provides a vernier caliper for same-side abutment measurement, in which two measuring claws can respectively abut against the same side of two targets to measure a size.
Referring to fig. 1 and 2, the vernier caliper of the present embodiment includes a main scale 1, a vernier scale 2, a fixed measuring claw 3, and a free movement measuring claw 4.
Those skilled in the art will appreciate that:
the scale is arranged on one surface of the main scale 1, and the surface of the main scale 1 provided with the scale is called as a scale surface. One end of the main scale 1 is a zero scale end, and the other end of the main scale 1 is a tail end;
the fixed measuring claw 3 is fixed at the zero scale end of the main scale 1, and the measuring edge of the fixed measuring claw 3 faces the tail end of the main scale 1;
the vernier 2 is assembled on the main scale 1, the swimming measuring claw 4 is fixed on the vernier 2, and the swimming measuring claw 4 can reciprocate along with the vernier 2 and the main scale 1.
The vernier caliper of the present embodiment is different from a conventional vernier caliper in the orientation of the measurement edge of the free measuring claw 4.
In the present embodiment, the orientation of the measuring edge of the free measuring claw 4 is identical to that of the fixed measuring claw 3, that is, the measuring edge of the free measuring claw 4 is also oriented toward the trailing end of the main scale 1, and when the vernier 2 is in the zero reference position, the measuring edge of the fixed measuring claw 3 and the measuring edge of the free measuring claw 4 are on the same plane, as shown in fig. 2, and overlap from the view point, so that the scale position indicated by the vernier 2 on the main scale 1 is the vertical distance between the measuring edge of the fixed measuring claw 3 and the measuring edge of the free measuring claw 4.
The swimming measuring claw 4 is arranged at the back of the main scale 1, so that the swimming measuring claw 4 does not form shielding to the scale surface, thereby being beneficial to an operator to observe the indication scale of the vernier 2.
The vernier caliper of the embodiment is mainly used for measuring the distance between two targets on the same side, and is particularly suitable for measuring the distance between two bolt holes on which bolts are mounted.
The following describes in detail how the center-to-center distance of two bolt holes to which bolts have been attached is measured using the vernier caliper of the present embodiment.
Referring to fig. 3, two bolts 5 in the drawing are two bolts 5 (the specification is the same) on a perforated plate, the vernier caliper of this embodiment is used to measure the center distance of the bolt hole where the two bolts are located, the measuring edge of the fixed measuring claw 3 is abutted against one bolt 5 (nut) first, then the vernier scale 2 is operated to move, the measuring edge of the free measuring claw 4 is abutted against the other bolt 5, and at this time, the scale indicated by the vernier scale 2 can be directly determined as the center distance of the bolt hole where the two bolts 5 are located. That is, when the vernier caliper of the present embodiment is used for measurement, the two measuring claws (the fixed measuring claw 3 and the free measuring claw 4) of the vernier caliper abut against the two measurement targets, respectively, and abut against the same side of the two targets, thereby achieving the distance measurement of both.
The measurement edges of the stationary measurement jaw 3 and the free measurement jaw 4 mentioned above refer to edges where the stationary measurement jaw 3 and the free measurement jaw 4 are in direct contact with an object to be measured when measurement is performed, and are common knowledge of those skilled in the art.
The orientation of the measuring edge mentioned above refers to the direction of the measuring edge perpendicularly outward.
The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model, therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model should be included in the scope of the present utility model.
