Measuring method for size of roll bearing block

Abstract

The invention relates to a measuring method for the size of a roll bearing block. The measuring method effectively solves the problems that the detection of the roll bearing block has higher requirements for a detection site, equipment and personnel, the measurement is restricted, and the need of actual measurement for the size of the roll bearing block cannot be met. Photography measurement is conducted on the roll bearing block to be detected to obtain measured three-dimensional point data of the surface of the bearing block, the flatness, span and degree of symmetry of the bearing block are analyzed and calculated by integrating the three-dimensional data collected by the photography measurement with design parameters of bearing block, analysis results are output in a report form, and the results of the flatness, the degree of symmetry and the span of the bearing block obtained through analysis and calculation are output in the report form and by imaging. According to the measuring method, a camera is adopted for obtaining a plurality of digital images of the roll bearing block, three-dimensional coordinates of feature points on the surface of the roll bearing block are obtained by conducting image processing, recognition and matching, spatial intersection and the like on the digital images, and the parameters of the bearing block are rapidly calculated by adopting a computer to realize the rapid and high-precision detection of geometric parameters of the bearing block.

Description

technical field [0001] The invention relates to a method for measuring the size of a roll bearing seat. Background technique [0002] In the steel plate rolling process, the rolling process has higher requirements on the spatial position of the rolls. The spatial position of the roll is directly related to the shape of the plate, the consumption of the roll and the stable operation of the equipment. Therefore, it is necessary to ensure the correctness of the spatial position of the roll in all stages of rolling mill design, manufacture, and installation. [0003] The spatial position of the roll is generally achieved by adjusting the window liner of the rolling mill to achieve its design position. However, in practice, it is found that only adjusting the window liner cannot fully meet the adjustment requirements of the spatial position of the roll. It is also necessary to ensure the parallelism and plane of the roll chock liner. Only when the degree and symmetry meet the de...

Problems solved by technology

[0009] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a method for measuring the size of the roll chock, which can effectively solve the problem that the real condition of the chock liner cannot be fully reflected when the roll chock is inspected. The requirements for equipment and personnel are relatively high, and the measurement is limited, which cannot meet the actual measurement needs of the roll chock size
