Description

Technical Field

[0001] The utility model relates to the technical field related to laser centering instruments, and in particular to an adjustable laser centering instrument. Background Art

[0002] Among the unplanned downtime of rotating equipment, a large part is caused by shaft misalignment. These unplanned downtimes reduce the equipment operation cycle, leading to increased maintenance costs and production losses. In addition, poor shaft alignment will increase the vibration and wear of the machine, increase energy consumption, and cause failures of bearings, seals and even couplings, causing safety accidents. Traditional gauge alignment takes a long time, has low accuracy, and cannot be adjusted in real time. Therefore, it is necessary to use an alignment instrument to align the equipment. The alignment instrument is an instrument that can find certain reference objects such as the middle and midpoint to determine the position. Because the laser is different from other light beams, it has strong penetrating power and is widely used for alignment. Laser alignment has a small accuracy error and can be adjusted in time. Accurate laser alignment and centering correction can extend the life of bearings, shaft seals, couplings and other parts of rotating equipment. The existing adjustable laser alignment instrument can basically meet daily use needs, but there are still some shortcomings that need to be improved.

[0003] It is not convenient to carry out stable fixed installation work for couplings or shafts of different diameters, which easily leads to low work efficiency and poor applicability. The angle of the measuring instrument is difficult to adjust during use, which is inconvenient to use. In this regard, this scheme specially proposes an adjustable laser alignment instrument to solve the above problems. Utility Model Content
