Embodiment Construction

[0018] Referring to the accompanying drawings, a rudder position adjustment measuring fixture includes a position pointer 1, a clamping lug 2 and an elastic pressing device 3. The position pointer 1 is a symmetrical structure, and its outer contour projection is the same as that of the lower part of the aircraft rudder. Pointer 1 has a sharp point 4 at the end, and sharp point 4 is perpendicular to the horizontal reference plane of the fixture; clamping lugs 2 are symmetrically distributed on both sides of position pointer 1, and its fitting surface is consistent with the shape of the aircraft wing surface; elastic pressing device 3 It is movably connected on the clamping lug 2. The elastic compression device 3 can adopt a screw tightening compression structure. Take the following steps when adjusting and measuring the rudder:

[0019] 1. Project the rudder installation and adjustment reference point from the top of the rudder to the lower part of the rudder as the reference ...

Abstract

The invention provides a rudder position adjusting and measuring clamp and method. The clamp comprises a position pointer, clamping lug pieces and an elastic compressing device, wherein the position pointer is of a symmetrical structure; the outer contour projection of the position pointer is the same as that of the lower portion of an airplane rudder; the end of the position pointer is provided with a sharp point perpendicular to the horizontal datum of the clamp; the clamping lug pieces are symmetrically distributed on the two sides of the position pointer; the attachment surfaces are consistent with the appearance airplane wing surfaces. The clamp has wide portability and can almost be applied to adjustment and measurement of rudder systems of various airplanes.

Description

technical field [0001] The application relates to the technical field of aircraft manufacturing and assembly, in particular to a rudder position adjustment measuring fixture and an adjustment and measurement method thereof. Background technique [0002] During the flight of the aircraft, by controlling the left and right yaw of the rudder system, the airflow acting on it is affected, thereby changing the force on the aircraft and realizing the yaw motion of the aircraft. Therefore, it is self-evident that the accuracy of the deflection of the rudder system has an impact on flight safety. [0003] In the production process of aircraft, how to effectively control and measure the deflection angle of the rudder system is very necessary. Since the adjustment of the rudder deflection angle needs to use the rudder itself as the measurement reference, and this reference is generally set on the top of the rudder, there is a great risk that the operator must carry out high-altitude o...
