Abstract
The invention discloses a method for detecting symmetry of cold rolling bearing seat lining plate. The detection method comprises the steps of when the bearing parts is in a static state, the origin of the coordinate system is established in the axis of bearing bore, using laser tracker for multi point detection, the symmetry value of the lining plate after assembly of the cold rolling bearing can be obtained via an analysis. The laser tracker is used to detect the symmetry of the cold rolling bearing seat lining plate to avoid the degree of symmetry does not meet the requirements of design and use caused by the influence of assembly fitter's personal skill quality, resulting in the formation of the cross-axis of the roll systems in the rolling working condition, thus further affecting the quality of cold rolling sheet. Laser tracker is used to detect the symmetry of cold rolling bearing, the inner hole axis is used as the benchmark, to ensure the benchmark unity between the measurement and design, improve the detection accuracy.
