Abstract
The utility model relates to a measuring instrument, particularly a width arm vernier caliper for the measuring the diameter of a steel cable, characterized in that the jaws of two tong feet for measuring the outer diameter of original vernier caliper are improved, namely, both opposite ends of the tong feet are respectively and vertically fixed with a flat plate, and the tong feet are symmetric left and right relative to a fixed part to form a broad jaw in the shape of a plane. The steel cable whose diameter is shorter than phi 60 mm can not fall into the gap between two strands in the measurement. The utility model has the advantages of reasonable design, simple structure, high precision, stable performance, etc.
Description
The utility model relates to a kind of surveying instrument, particularly specializes in the metering measurer that detects the wire rope footpath.
Existing vernier caliper mainly is made up of scale, slide rule, decides the slide rule front portion and is provided with and combines upper and lower each a pair of pincers pin, offers the edge of a knife shape jaw that can survey internal diameter or external diameter on the measuring point of upper and lower pincers pin respectively.When needs were measured diameter in kind, the internal diameter of two jaws of vernier caliper and tested material object or external diameter contacted just can record its size.And when with this vernier caliper measurement wirerope diameter, use the edge of a knife shape jaw of surveying external diameter to tend to be strayed in the slot of two strand steel wire ropes, thereby the measuring error of causing.This brings difficulty for manufacturer that makes wire rope and the user who uses this product in the detection in rope footpath, often cause error in judgement.
The purpose of this utility model provides a kind of improvement, specializes in the vernier caliper that detects the wire rope footpath, and characteristics are that jaw is made wide.Like this, make the testing staff when measuring steel wire rope rope footpath, not only feel convenient, and stoped jaw to be strayed into the detection error that causes in the two strand steel wire rope slots effectively.
According to vernier caliper of the present utility model, mainly two jaws that clamp pin of original survey external diameter have been done improvement, this jaw no longer is edge of a knife shape, but be the plane of expansion, just two pincers pin opposite ends separately vertical fixing one flat plate is arranged, their equal and opposite in directions and with respect to the fixed part left-right symmetric.Vernier caliper replaces the linear jaw of edge of a knife shape that the wire rope rope is directly measured with the plane wide jaw of flat board like this, can prevent effectively that jaw embedding strand wire slot is interior and can make measuring steel wire rope actual diameter more reasonable and accurate.
Fig. 1 represents the plan view of the utility model vernier caliper;
Fig. 2 represents the cut-open view that I-the I line is done along Fig. 1;
The A of Fig. 3 presentation graphs 1 is to view;
Described in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, according to wire rope of the present utility model calibrate with wide pincers vernier caliper comprise a scale 1, one slide rule 2 and two flat boards 6,6 '.The front portion of said scale 1 and slide rule 2 be provided with upper and lower each a pair of pincers pin 3,3 of combining ' and 4,4 '.Top pincers pin 3,3 ', offer edge of a knife shape jaw also according to original design.Bottom pincers pin 4,4 ' opposite end separately the vertical fixing flat board be 6,6 '.Dull and stereotyped 6,6 ' a side on be provided with two vertically extending wall sections separately and constitute groove 7,7 ' or the elongated slot (not shown) of directly setting etc., said dull and stereotyped 6,6 ' and jaw 4,4 ' fixedly be dull and stereotyped groove 7,7 ' respectively with pincers pin 4,4 ' the end inlay mutually and weldbonding, see Fig. 2,3.
On the width and selection highly of flat board, consider that wire rope general diameter scope is at φ below 60 millimeters, then maximum burst of distance is 30 millimeters between its two strands, therefore it is more satisfactory that dull and stereotyped width is measured outer jaw sheet width by above-mentioned strand apart from conduct, and height is except considering burst distance, also need measure conveniently, select that to be slightly larger than the sheet width size better for use, so generally adopt the 40-50 millimeter.
Wide pincers slide measure of the present utility model is the requisite measurer in measuring steel wire rope footpath, and it can make things convenient for and the actual outside diameter of measuring steel wire rope reliably. And on the measuring steel wire rope with edge of a knife shape jaw slide measure relatively, on the accuracy of manufacture, can be improved, also have simple in structure, stable performance, the advantage such as reasonable in design.
Claims (3)
1, a kind of wire rope is calibrated with wide pincers vernier caliper and is comprised scale 1, slide rule 2, and upper and lower each a pair of pincers pin 3,3 that combines by scale and slide rule front portion ' and 4,4 ', it is characterized in that clamping pin 4,4 ' opposite end separately vertical fixing one flat plate 6,6 ' and with respect to the left and right symmetry of fixed part is arranged.
2, vernier caliper according to claim 1, it is characterized in that said dull and stereotyped 6,6 ' a side on be provided with two vertically extending wall sections separately and constitute groove 7,7 ' or connect elongated slot is set, said flat board and jaw fixedly be dull and stereotyped groove 7 and 7 ' respectively with pincers pin 4,4 ' the end inlay mutually and weldbonding.
3, according to claim 1 and 2 said vernier calipers, it is characterized in that dull and stereotyped width is 30mm, highly be 40-50mm.
