Detailed description of the invention
Below the specific embodiment of the present invention is further illustrated:
As shown in Figure 1, a kind of device of measuring the dynamic accuracy of alignment of edger roll, comprises laser aid 1 and elastic thread 2, and described elastic thread 2 is figure of eight level and is wrapped on edger roll 4, and laser aid 1 is along roller-way center line Emission Lasers light beam 3;
Its measuring process is: first use laser aid 1 along roller-way center line Emission Lasers light beam 3, as rolling center reference line, then elastic thread 2 being to figure of eight level is wrapped on an opposite roller 4, the aperture of one opposite roller 4 is adjusted into 1200mm, records " 8 " word crosspoint of elastic thread 2 to the horizontal range X of rolling center reference line
1, then the aperture of an opposite roller 4 is adjusted into 1400mm, record " 8 " word crosspoint of elastic thread 2 to the horizontal range X of rolling center reference line
2, then the aperture of an opposite roller 4 is adjusted into 1600mm, record " 8 " word crosspoint of elastic thread 2 to the horizontal range X of rolling center reference line
3, then the aperture of an opposite roller 4 is adjusted into 1800mm, record " 8 " word crosspoint of elastic thread 2 to the horizontal range X of rolling center reference line
4, then the aperture of an opposite roller 4 is adjusted into 2000mm, record " 8 " word crosspoint of elastic thread 2 to the horizontal range X of rolling center reference line
