[0002] The spoiler proportional converter anti-rotation assembly is an important component of the flight control system. After the 2020 revision, Boeing refined the inspection standards and measurement requirements. Before the revision, it was only required that the movement of the sector disk should not exceed 3.18mm, or the angle should not exceed 2° when 120 pounds of force is applied to the output shaft in both directions at any position. After the revision, the measurement positions increased from 1 to 4, the measurement data increased from 2 to 8, and the measurement accuracy increased from 3.18mm of sector disk movement to 0.41mm of output shaft movement, corresponding to a rotation angle of 2°. If the standards are not met, the proportional converter needs to be replaced.

[0003] However, there are currently no suitable tools on the market, which means that the implementation is greatly affected by external factors such as jitter and human operation, making it difficult to accurately measure data, affecting the judgment of component performance, resulting in disassembly or replacement, and increasing maintenance costs.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] like Figs. 1-3 As shown, the utility model proposes a spoiler proportional converter anti-rotation assembly measuring fixture, including a measuring instrument clamping and fixing base 1, one side of the measuring instrument clamping and fixing base 1 is extended and connected with a measuring instrument clamping and adjusting assembly 2, a clamping screw 3 is provided on one side perpendicular to the measuring instrument clamping and fixing base 1, a locking butterfly nut 4 is threadedly connected to the clamping screw 3, a locking butterfly nut 4 is slidably installed on the clamping screw 3, an expansion assembly 6 is provided at the end of the clamping screw 3 and the other side of the expansion assembly 6 is connected and fixed to the clamping screw 3 by a fixing screw 7, and a fixing screw 8 is arranged in a circumferential array on the expansion assembly 6.

[0018] like Fig. 2 As shown, the expansion assembly 6 includes an expansion adjustment member 9 and an expansion member 10. The expansion adjustment member 9 is arranged at the end of the clamping screw 3 and is fixed to the clamping screw 3 by a fixing screw 7. One side of the expansion adjustment member 9 is arranged in an inverted cone shape, and the end of the expansion adjustment member 9 can pass through the variable groove 15. The expansion member 10 slides on the clamping screw 3 and is sleeved and wrapped around the outside of the expansion adjustment member 9. The variable groove 15 is vertically passed through the expansion member 10.

[0019] like Figs. 2-3 As shown, the measuring instrument clamping adjustment assembly 2 includes a clamping adjustment guide rod 11, a measuring instrument clamping adjustment seat 12, a clamping adjustment screw 13 and an adjusting handwheel 14. The clamping adjustment guide rod 11 extends from one side of the measuring instrument clamping fixing seat 1 and is slidingly connected to the measuring instrument clamping fixing seat 1. The measuring instrument clamping adjustment seat 12 is fixed on the other side of the clamping adjustment guide rod 11. The inner wall of the measuring instrument clamping fixing seat 1 and the inner wall of the measuring instrument clamping adjustment seat 12 are both provided with a silicone protective pad 16. The clamping adjustment screw 13 is threadedly connected to the measuring instrument clamping fixing seat 1 and passes through the middle of the measuring instrument clamping adjustment seat 12. The adjusting handwheel 14 is provided on the clamping adjustment screw 13.

[0020] During specific use, the adjusting hand wheel 14 is turned, and the adjusting hand wheel 14 drives the clamping adjusting screw 13 to rotate spirally on the measuring instrument clamping fixing base 1. Under the sliding action of the clamping adjusting guide rod 11 and the measuring instrument clamping fixing base 1, the measuring instrument clamping adjusting base 12 and the clamping adjusting guide rod 11 are synchronously moved closer to or away from the measuring instrument clamping fixing base 1, so that the distance between the measuring instrument clamping adjusting base 12 and the measuring instrument clamping fixing base 1 is adjusted, thereby facilitating the placement of the angle measuring instrument between the measuring instrument clamping adjusting base 12 and the inner wall of the measuring instrument clamping fixing base 1. At this time, the silicone protective pad 16 plays a protective role to prevent damage to the angle measuring instrument.

[0021] The head position of the expansion adjustment member 9 is connected to the flow plate ratio converter, and then the locking butterfly nut 4 is rotated on the pressing screw 3. The locking butterfly nut 4 moves toward the direction of the expansion adjustment member 9 and contacts the installation stop pad 5 during the movement, pushing the installation stop pad 5 to move toward the expansion adjustment member 9. When the installation stop pad 5 moves to the position of the expansion member 10, it half wraps the tail end of the expansion member 10 and moves synchronously with the expansion member 10. Then, the expansion member 10 is opened and the distance of the variable slot 15 is enlarged at the inverted truncated cone end of the expansion adjustment member 9, thereby achieving the effect of the expansion member 10 being supported inside the installation stop pad 5 and the expansion member 10 being compressed and expanded, thereby achieving fixation;

[0022] Finally, the angle meter is reset to zero, and then a force of 120 pounds is applied to the entire device. The angle of rotation is measured by the angle meter to determine whether it meets the inspection standards and measurement requirements.
