Abstract

The utility model discloses a vernier for measuring which composes of a vernier body, a vernier travel piece flexibly connected on the vernier body, and graduations. A positioning block is provided on one end of the vernier body, which equips with positioning faces perpendicular with each other on the two side surfaces adjacent to the vernier body. A travel piece positioning block is provided on the vernier travel piece which equips with two travel piece positioning faces perpendicular with each other on the two side surfaces adjacent to the vernier travel piece. The vernier of the present utility model is of simple structure with little additional accessories, which is convenient to operate with low cost. The time spent to measure a continuous production line is not more than the time spent by using a roll gap meter. Compared with measuring method using a feeler gauge + vernier, the time used is shortened obviously. The utility model is provided with high measuring precision and can effectively improve the quality of castings and increase the structure property thereof.

Description

A kind of measurement vernier scale

Technical field

The utility model relates to a kind of vernier scale of measuring distance, especially measures the vernier scale of conticaster roll gap and roller bending value.

Background technology

With steel (iron) water in mold the casting of conticaster, obtain required steel billet in the steel industry with high-temperature liquid state.All will be with a plurality of rollers, setting in pairs in the conticaster commonly used, roller arranged in pairs, one of them is commonly referred to the inner arc roller, and another is called the outer arc roller, and the outer arc roller is fixed, and the inner arc roller can move; Distance between the inside and outside arc roller is called opening degree, and opening degree is an important indicator in the conticaster, and it directly influences slab quality, loosens as continuous casting billet structure density, inside etc.; Conticaster in use all will be measured its opening degree, and its opening degree is regulated in the position of the relative outer arc roller of adjustment inner arc roller.Two kinds of mode and equipment that detect opening degree are arranged in the prior art, a kind of is to detect with the higher roll gap meter of automaticity, roll gap meter comprises a plurality of sensors, computer hardware and software etc., need professional person's operation through training, and cost an arm and a leg, the separate unit price is all more than 1,000,000, and in use effect is unsatisfactory, and the confidence level of measuring numerical value is poor; The second way is to adopt the mode of original feeler gauge+vernier scale; Be placed between the inside and outside arc by manually filling in rail, measure the size of feeler gauge again with vernier scale, obtain the opening degree between every pair of rollers; This kind mode not only efficient is low, measure the chronic of a cover conticaster, and under all a lot of site environment of high temperature, dust, greasy dirt, and be subjected to place restriction, the operator measures very inconvenient with feeler gauge, measurement result is usually inaccurate, and error is bigger, often surpasses the error range of technological requirement.Above-mentioned two kinds of metering systems and measuring equipment all can not adapt to the needs of execute-in-place, its measurement result often surpasses the error range of technological requirement, so a kind of simple in structure, easy to use, measurement vernier scale that measuring accuracy is high of exploitation becomes market and user's common hope.

Summary of the invention

The utility model is at the above-mentioned deficiency of measuring conticaster opening degree measurement mechanism in the prior art, and a kind of simple in structure, measuring accuracy is high, Measuring Time is short measurement vernier scale is provided.

The technical scheme that this usefulness is novel: a kind of measurement vernier scale comprises scale main body and the scale moving body that is movably connected on the scale main body, scale; It is characterized in that: the end in the scale main body is provided with locating piece, and two adjacent side of this locating piece and scale main body are provided with the side, location, and side, two location is perpendicular; The scale moving body is provided with the moving body locating piece, on two adjacent sides of running fix piece and scale moving body, is provided with the moving body locating surface, and two moving body locating surfaces are perpendicular;

Described two sides, location and moving body locating surface all are through processing the positioning reference plane during respectively as measurement.

Measurement vernier scale of the present utility model has the following advantages:

1, simple in structure; With respect to the vernier scale of prior art, to increase part few, simple in structure, with low cost.

2, easy to use; The efficiency of measurement height, the operator directly measures opening degree with vernier scale, the high temperature in the site environment, dust, greasy dirt etc. to influence very little, the time of measuring a continuous casting line generally all is no more than expensive roll gap meter institute's time spent, than what spent with the measurement of feeler gauge ten vernier scales

Time shortens greatly,

3, measuring accuracy height can satisfy arts demand fully, effectively improves the quality of foundry goods, improves it

Structure property.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described

Accompanying drawing is the utility model vernier scale synoptic diagram.

Embodiment

In figure, 1---the scale main body, 2---the scale moving body, 3---locating piece, 4---the side, location, 5---the moving body locating piece, 6---the moving body locating surface, 7---scale;

Vernier scale of the present utility model, comprise scale main body 1 and scale moving body 2, scale moving body 2 is movably connected on the scale main body 1, can move left and right moving, move at scale main body 1 and scale and all to be provided with scale 7 on 2, it is, identical when scale 7 is measurement with scale, the effect of vernier scale in the prior art in order to read the scale of measured value.

Scale main body 1 is provided with locating piece 3, and locating piece 3 is roughly perpendicular with scale main body 1, and locating piece 3 is provided with side 4, location with two adjacent side of scale main body 1, and side, these two location 4 is vertical mutually.

Scale moving body 2 is provided with moving body locating piece 5, moving body locating piece 5 is roughly perpendicular with scale moving body 2, on two adjacent sides of moving body locating piece 5 and scale moving body 2, be provided with moving body locating surface 6, these two moving body locating surfaces 6 are vertical mutually.

Two location side 4 and moving body locating surfaces 6 all are that its surfaceness is had relatively high expectations through the face of processing, and the positioning reference plane when measuring contacts with the side of inner arc roller or outer arc roller respectively.

The using method of the utility model vernier scale: two adjacent positioned sides 4 of scale main body 1 and locating piece 3 are leaned against respectively on the cylindrical periphery of outer arc roller, scale moving body 2 moves right, make two adjacent moving body locating surfaces 6 on scale moving body 2 and the moving body locating piece 5, contact with the cylindrical periphery of inner arc roller respectively, after the fixed numbers, just can read the opening degree between this inside and outside arc roller from the scale 7, according to technological requirement, determine whether to adjust the value range of this opening degree and adjustment again.Rotate inside and outside arc roller during measurement respectively, can measure the bending value of roller equally.
