Description

Technical Field

[0001] The utility model relates to the technical field of rail transit vehicle measurement, in particular to a device for measuring the verticality of a side wall of a rail transit vehicle body. Background Art

[0002] Aluminum alloy car body is the core component of rail transit vehicles. In order to ensure the symmetry of both sides of the car body, the pre-assembly process of aluminum alloy car body assembly needs to adjust the verticality of the large side wall components. However, the large side wall components have their own curvature, and ordinary vertical measurement devices cannot be used. If the large side wall components are biased to either side, the cross-section diagonal size will be out of tolerance after the car body is completed. The asymmetry of the two sides will affect the normal installation of the interior in the final assembly process, and more seriously affect driving safety and affect the vehicle's passing of the limit test. After the car body is welded, if the cross-section diagonal size is seriously out of tolerance, it will not be able to be adjusted and repaired, and the car body will eventually be scrapped. A series of adjustments or scrapping of the car body will cause very large economic losses. Therefore, it is particularly important to control the inclination of the side wall during the car body production stage. Utility Model Content
