With the increasing upgrading and upgrading speed of the airplane, in order to meet the increasing requirements of leveling measures and reduce the labor intensity of operators, a set of more advanced airplane leveling tool and a more advanced airplane leveling measuring method are urgently needed.
The traditional method for horizontally measuring points on the machine body and the mainly used tool are mutually perpendicular rigid T-squares, wherein the longer side of each T-square is provided with scale marks, and the end part of the other side of each T-square is of a sharp point structure. When the tool is used for measuring the horizontal point, an operator firstly needs to adjust the posture of the T-square support, so that the longitudinal air bubbles and the transverse air bubbles on the T-square support are located in the middle of the visible area, then the operator makes the sharp point structure on the shorter side of the T-square contact with the horizontal measuring point on the airplane, and then another operator uses the level meter to read the scale mark on the longer side of the tool at a distance away from the airplane. Because the frock size is great and comparatively heavy, plus T square support does not examine the requirement certainly to make, the process that the adjustment frock bubble is located visual regional intermediate position wastes time and energy on the one hand, and on the other hand, the T square support is because long-time business trip uses, and the precision also descends gradually.
