Abstract

The invention discloses a laser assisted centering device for assembling large-diameter equipment, and the device comprises a center rod, wherein a bubble level is connected to the upper end of the center rod, a cross laser head is connected to the lower end of the center rod, and a leg is connected to the center rod. When centering the large-diameter equipment, the laser assisted centering deviceprovided by the invention directly identifies the center point by a cross laser line to obtain an intuitive result, thereby eliminating the need of pulling and measuring links, avoiding errors causedby indirect measurement, having higher accuracy, large applicable diameter range, quick adjustment with no need for other auxiliary instruments and measuring tools, simple operation and reliable results, and reducing operating steps, workload as well as worker skill threshold.

Description

technical field

[0001] The invention belongs to the technical field of mechanical manufacturing and assembly, and relates to a laser-assisted centering device for large-diameter equipment assembly. Background technique

[0002] Among mechanical products, there is a type of large-diameter equipment (for example: a turntable for oil drilling rigs). When assembling with other equipment, it is necessary to find the center of the equipment diameter and ensure concentric assembly with other assembly parts. However, because the center of the diameter of the equipment does not fall on the entity, it is difficult to mark in the suspended position. Generally, during assembly, two wire ropes need to be pulled on the horizontal plane so that the length of the wire rope is equal to the diameter of the diameter. The intersection of the two ropes is the passage. Then hang a plumb bob at the intersection point, take the position pointed by the plumb bob as the center of the path, and then a...
