Abstract
The invention relates to measuring calipers comprising a handle. First caliper arms are symmetrically hinged to the end portion of the handle. A second caliper arm between the two first caliper arms is also hinged to the end portion of the handle. With simple structure and easy installation, the measuring calipers may achieve measurement of external dimensions and external diameters with the two symmetric caliper arms hinged to the end portion of the handle, and measurement of internal diameters and internal dimensions with second jaws on the second caliper arm. The measuring calipers have variable measuring modes, effectively achieve integrated measurement of external diameters, internal diameters, external dimensions, and internal dimensions, achieve high measuring efficiency, and increase production efficiency.
Description
Technical field
The present invention relates to measuring equipment, relate in particular to a kind of measurement clamp.
Background technology
In forging process, in order to guarantee the measurement fast, accurately to high temperature forging product, need to use measurement clamp, but current existing clamp structure can only meet the function of independent measurement inside dimension or internal diameter and independent measurement external diameter and outside dimension, so can integrate in the urgent need to a kind of the measurement card wrench structure of measuring external diameter and internal diameter, outside dimension and inside dimension.
Summary of the invention
The applicant, for above-mentioned existing issue, is studied improvement, and a kind of measurement clamp rational in infrastructure are provided, and effectively realizes the integrated measuring of external diameter and internal diameter, outside dimension and inside dimension.
The technical solution adopted in the present invention is as follows:
Measurement clamp, comprise handle, symmetrical hinged the first tong arm in the end of described handle, and between two first tong arms, hinged the second tong arm also in the end of described handle.
Its further technical scheme is:
Described two first tong arms hinged formation each other " V " shape;
The end that is positioned at each first tong arm all arranges the first jaw that curves inwardly and be shaped;
The end of described the second tong arm arranges the second jaw of two outwardly-bent shapings, forms " V " shape between two second jaws;
Described the first jaw and the second jaw are arc;
Described the first tong arm, the end of the second tong arm and handle is all hinged by round pin.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, simple installation, by two first tong arms symmetrical and that be hinged on handle end, can realize the measurement to outside dimension and external diameter, by the second jaw on the second tong arm, can realize the measurement to internal diameter and inside dimension simultaneously, and between two first tong arms and the second tong arm, can also meet the measurement of less external diameter, metering system is changeable, effectively realize the integrated measuring of external diameter and internal diameter, outside dimension and inside dimension, measured efficiency high, improved production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, handle; 2, round pin; 3, the first tong arm; 4, the second tong arm; 310, the first jaw; 302, the second jaw.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, a kind of measurement clamp, comprise handle 1, and at symmetrical hinged the first tong arm 3 in the end of handle 1, the end that is positioned at each first tong arm 3 all arranges the first jaw 301, two first tong arms 3 hinged formation each other " V " shape that curves inwardly and be shaped.Between two first tong arms 3, hinged the second tong arm 4 also in the end of handle 1.The end of the second tong arm 4 arranges and between the second jaw 401, two second jaws 401 of two outwardly-bent shapings, forms " V " shape.The first jaw 301 and the second jaw 401 are arc.Above-mentioned the first tong arm 3, the second tong arms 4 are all hinged by round pin 2 with the end of handle 1.
Specific works process of the present invention is as follows:
As shown in Figure 1, when needs are measured large external diameter or large scale series products, operating personnel only need to be by mobile two the first tong arms 3, after two first tong arms 3 are broken into two with one's hands, measured product is placed between two first tong arms 3 simultaneously, after the first jaw 301 contacts with measured product periphery, the distance between two first tong arms 3 is external diameter or the outside dimension of this product.Simultaneously when needs are measured all the other sizes, can be by the coordinating of the first tong arm 3 and the second tong arm 4, the first jaw 301 can be realized the measurement to product outside dimension, external diameter with the second jaw 401 with contacting also of measured product periphery.
On the contrary, when needs are measured internal diameter, the second tong arm 4 is stretched in the endoporus of measured product, by two second jaws 401, contact the measurement that can realize internal diameter or inside dimension with product internal face.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
