Description

Technical Field

[0001] The utility model relates to the technical field of angle measurement, and in particular to a rudder surface angle measuring device. Background Art

[0002] During the manufacturing process of aircraft parts, it is necessary to check whether the installation positions of the aircraft's trailing edge flaps, leading edge flaps, spoilers, ailerons and other control surfaces meet the design requirements. If the installation positions meet the requirements, it is necessary to further check whether the deflection angles of the control surfaces meet the design requirements. At this time, it is necessary to measure the deflection angles of the wing control surfaces. The commonly used method is to use an angle gauge for measurement, but in many cases, due to space limitations, a smaller angle gauge cannot read accurately when the product is large, and a larger angle gauge cannot be placed in the product, resulting in a large measurement error. Therefore, it is necessary to design a special angle measurement tool for the deflection angles of the wing control surfaces. Utility Model Content

The utility model fixes the measuring tool dial on the main wing, fixes the measuring tool pointer on the wing aileron, drives the measuring tool pointer to deflect through the wing aileron, converts the wing aileron deflection angle into the deflection angle of the measuring tool pointer, and enlarges the measuring diameter, which not only makes the angle reading easier, but also greatly improves the accuracy of the reading and measurement, and is less restricted by the measurement space, and can be applied to the measurement of the deflection angle of the rudder surface of various aircraft.
