A laser alignment device and alignment method thereof

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.

Description

technical field [0001] The invention relates to a laser centering device, which is a tool for adjusting the supporting legs of the laser centering device so that the dummy shaft is at the axial center of the bearing bush, and a laser instrument on the dummy shaft is used to realize the centering operation of the bearing bush. It belongs to the field of laser centering installation of bearing bushes of complete sets of equipment such as large multistage compressors and centrifugal pumps. The invention also relates to a centering method using the laser centering device. Background technique [0002] With the vigorous development of my country's manufacturing industry, large-scale machinery and equipment have also been widely used in many enterprises, and have become the economic lifeline of enterprises. However, for some large-scale mechanical equipment such as multi-stage compressors, centrifugal pumps and other complete sets of equipment, the centering installation of the b...

Problems solved by technology

However, for some large-scale mechanical equipment such as multi-stage compressors, centrifugal pumps and other complete sets of equipment, the centering installation of the bearing bush has become a difficult installation problem. The existing method is to pull the steel wire above the bearing bush, and continuously adjust the height of the steel wire to make it At the concentric position of the bearing bush, then use the power cord to connect the steel wire and the bearing bush, and connect the earphone to the power cord. If the sound is heard, it means that it has been centered. If the sound is intermittent, the height of the steel wire needs to be readjusted. The progress of the centering of the bearing bush is slow, and the earphone listening method requires more skilled employees to operate, and the hands should not shake during operation. This method has great limitations. , low efficiency, labor-intensive and time-consuming, and the accuracy of the centered bearing bush is not high, the wear of the multi-stage shaft or centrifugal shaft of the installed large-scale mechanical equipment is high during work, and the service life is short

[0003] After the development of laser technology, many people have used lasers to develop some centering devices and operations using lasers. These laser centering devices have good centering effects, but they are expensive and belong to precision instruments. The requirements of practical users are relatively high, among which the centering method is more complicated, and the calculation process required is very complicated, which is difficult for ordinary people to master and must be operated by professionals, which greatly reduces the practicability of this technology
