Abstract
The invention, which belongs to the measurement technology field, relates to a two roller parallelism measuring instrument and a corresponding measuring method. The measuring instrument comprises: a first measuring flat, which is used to accommodate a first displacement sensor; a second measuring flat, which is used to accommodate a second displacement sensor. The first measuring flat and the second measuring flat respectively possess a first support body and a second support body and are connected with each other through a lockable shaft which is installed with an angular displacement sensor. The first support body and the second support body respectively possess supporting recesses which are tangent to two buses of a cylindrical surface of a reference roller. The recesses of the first support body and the second support body are symmetrical based on an axis of a shaft when the first support body and the second support body are in an angular locking position.

Embodiment
Embodiment mono-
The present embodiment is that a kind of steel rolling roller is to parallelism measuring instrument, as shown in Figure 1, comprise dull and stereotyped 1 (massive plate) of the first measurement of positioned vertical the first displacement transducer 3 and dull and stereotyped 6 (tablets) of the second measurement of positioned vertical second displacement sensor 8, the first measurement flat board and second is measured dull and stereotyped lower surface and is fixedly connected with 7 with the first and second supports 2 of V font respectively.Between two measurement flat boards, by being housed, the lockable rotating shaft of angular displacement sensor 5 connects.Second measures dull and stereotyped 6 the telescopic location of one end plug-in mounting two thimble 9.The cone end of two location thimbles 9 through the second measurement flat board 6 after, insert first and measure in the corresponding pilot hole of dull and stereotyped 1 end face, form locking device, realize the lock in place of two measurement flat boards.When location thimble 9 is deviate from from pilot hole, two measure dull and stereotyped can relatively rotating around the axis of angular sensor 5.The first and second supports V-arrangement notch down can be tangent with periphery two place's buses of reference roller.When in angle latched position, the V-arrangement notch of the first and second supports is about shaft axis (or the zero graduation line) symmetry of angular displacement sensor 5.First measures on dull and stereotyped 1 along shaft axis direction arrangement level meter 4.
During use, as shown in Figure 2, measuring instrument is placed in one, and right reference roller J is upper for roller, and displacement transducer can adopt conventional dial gauge, points to another velamen and surveys roller B.When 1 during with 6 mutual locked connection, because roller is to not parallel, 3 can record roller spacing minimum value, and now 8 can not record roller spacing minimum value.When 1 and 6 disengagement lockings are connected, by angle a of 8 rotation, 3 and 8 can record roller spacing minimum value simultaneously.3 and 8 of the present embodiment adopts the band sounding rod dial gauge of contact, lays respectively at and measures dull and stereotyped two ends, dull and stereotyped perpendicular to measuring.Angular displacement sensor 5 can adopt bevel protractor to replace.Level meter 4 is for confirming the horizontal level of measuring instrument, also can auxiliary base roller and the horizontal adjustment of measured roller.
While 1, measuring, according to following steps, carry out:
The first step, reference roller and measured roller are adjusted to respectively after horizontal level, measure the dull and stereotyped V-arrangement with the first and second supports in first, second of angle latched position, support notch and be placed in the reference roller of level with the tangent mode of reference roller periphery two place's buses respectively;
Second step, by measuring dull and stereotyped around the reciprocal turn of reference roller axis first, find the first minimum distance position between the first displacement transducer place reference roller and measured roller, rotate support 2 and 7 simultaneously, and observe 3 reading, when observing large → little → large turning point, by 2, be fixed on the minimum place of 3 readings, recording the first minor increment L1 (as can not directly record, can be referring to Fig. 3, be not difficult indirectly to be recorded by parameters such as reference roller, measured roller radiuses), fix the first measurement dull and stereotyped;
The 3rd step, disengagement 9, remove first and second and measure dull and stereotyped angle locking, by measuring dull and stereotyped around the reciprocal turn second of reference roller axis, find the second minimum distance position between second displacement sensor place's reference roller and measured roller, rotate the reading of 7 observations 8, when observing large → little → large turning point, by 7, be fixed on 8 readings minimums and locate, record the second minor increment L2 and measure dull and stereotyped relative rotation a with first and second;
The 4th step, by first, second minor increment L1, L2 and relative rotation a substitution cosine law formula
try to achieve the measured roller adjustment amount m (referring to Fig. 4) of measurement demand.
For example (referring to as Fig. 3) reference roller and measured roller radius are 100mm, and V-arrangement support 2 and 7 subtended angles are 90 °, and 3 readings are by 3 l that record
1=500mm, 8 readings are by 8 l that record
2=500.5mm, rotation angle a=0.5 °.
: L
01=L
02=100/cos45 °=141.4mm, L

01+ l
1+ r
x1=741.4mm, L
2=L
02+ l
2+ r
x2=741.9mm, parallel adjustment amount m ≈ 6.5mm.Due to the 0.5mm only of roller pitch difference now, so can obviously improve roller to parallel adjustment precision.
As can be seen here, the present embodiment can not only obtain the roller spacing at two ends, and can obtain the angle between the roller distance measurement line of two ends.Adopt this roller to measure parallelism measuring instrument, simply, conveniently, can provide rapidly roller to parallel adjustment direction and concrete numerical value, alignment error can be controlled in roller spacing 0.5% in, roller is improved greatly to parallel adjustment precision, and can avoid making repeated attempts and groping in blindness adjustment process, save a large amount of repair times; Contribute to reduce the problems such as steel belt deviation, coil of strip is wrinkling and overflow, promote the lifting of output and product quality.
In addition to the implementation, the present invention can also have other embodiments.For example, locking device also can adopt threaded fastener, and support also can adopt U-shaped or other notch structure.On measuring principle of the present invention basis, sensor can be both contact, as micrometer indicating gauges such as the dial gauge with sounding rod, clock gauge etc., also can be contactless photoelectric displacement sensor, as laser displacement sensor, and its output signal through microprocessor computing numeral show (when it is laser displacement sensor, the present invention by have be applicable to farther apart from roller the advantage to the measurement of paralleism).All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
