Description

Technical Field

[0001] This utility model relates to the field of armored vehicle assembly and inspection, specifically a tool for detecting the verticality of cylindrical attachments on the outer surface of armored vehicles. Background Technology

[0002] To ensure strong ballistic protection for armored vehicles, composite armor is widely used in various types of armored vehicles. As the most effective protection for armored vehicles and drivers, improper installation of composite armor not only affects the appearance of the armored vehicle but also directly impacts its service life and the driver's safety. The perpendicularity of the cylindrical mounts on the outer surface of the armored vehicle plays a decisive role; poor perpendicularity leads to an angle between the composite armor and the vehicle body, resulting in inadequate fit and making the composite armor more vulnerable to penetration.

[0003] For welding cylindrical mounts onto the outer surface of the vehicle body, only visual inspection and a vertical measuring ruler can be used. Due to factors such as the weld seam, both of these methods suffer from inaccurate inspection and inconvenient measurement. Utility Model Content
