Abstract

The invention relates to a laser centering device. The laser centering device is mainly composed of a laser instrument, a false axis, a false bearing bush, a supporting leg and a balancing device; the laser instrument is arranged on the false axis, threaded holes are respectively arranged at 0 DEG, 180 DEG, 225 DEG, and 315 DEG parts at two sides of the false bearing bush, the supporting leg is connected with the false bearing bush through the thread, and the extension cord of the supporting leg passes through the centre. The invention further relates to a method for centering by using the laser centering device, the method comprises the steps of enabling the axes of the false axis and the axes of the bearing bush to be on the same horizontal level by regulating the length of the supporting leg according to the diameters of different bearing bushes, and then centering through the laser instrument. The device disclosed by the invention is simple, practical and reliable, the difficulty in the centering operation of the traditional multi-stage bearing bush can be solved, the centering precision is high, the professional in the centering operation of the multi-stage bearing bush is reduced, and the labor in the bearing bush centering operation is saved.
