Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of helicopter tail rotor assembly tooling, and more specifically, to an adhesive tool for a helicopter tail rotor support member. Background Art
[0002] The helicopter tail rotor is a component used to balance the counter torque and control the helicopter's heading. Generally, the structure of the tail rotor is as Figures 1-2 shown. The tail rotor includes a flexible beam 100 connected to the helicopter drive component, a support member 200 mounted on the flexible beam 100, and blades (not shown) mounted on both ends of the flexible beam. The support member 200 includes a first support member 2001 and a second support member 2002. The first support member 2001 and the second support member 2002 are respectively sleeved with a sealing rubber sleeve 400 on the sleeves 300 of the two side blades. Among them, the support member 200 is an important part of the tail rotor blade, which plays a role in supporting the sealing rubber sleeve 400 and the sealing sleeve 300. Both the first support member 2001 and the second support member 2002 are made of non-metallic materials, and each includes an upper support plate 2003 and a lower support plate 2004 that are fitted together up and down and fixed by connecting screws 500. After applying glue to the bottom end of the upper support plate 2003 and the top end of the lower support plate 2004, they need to be adhesively bonded to the upper surface and the lower surface of the flexible beam 100 respectively. The installation position tolerance of the bonding position of the upper support plate 2003 and the lower support plate 2004 on the flexible beam 100 is required to be 0.01, and the installation accuracy requirement is relatively high.
[0003] Currently, for the installation of the existing support member adhesively bonded to the flexible beam, usually, a worker uses a measuring ruler to measure and mark the installation positions of the upper support plate and the lower support plate on the upper and lower surfaces of the flexible beam, and then manually adhesively bonds the upper support plate and the lower support plate according to the marked positions. However, this manual measurement and marking method has a large human subjective factor, often resulting in the installation accuracy of the support member not meeting the predetermined requirements, a high rejection rate, and a low assembly efficiency.
[0004] Therefore, how to provide an adhesive tool for a helicopter tail rotor support member that can not only ensure the installation accuracy requirements of the support member and the flexible beam but also improve the assembly efficiency is an urgent problem to be solved by those skilled in the art. Summary of the Invention
[0005] In view of this, the present invention provides an adhesive tool for a helicopter tail rotor support member that can not only ensure the installation accuracy requirements of the support member and the flexible beam but also improve the assembly efficiency.
[0006] To achieve the above object, the present invention adopts the following technical solutions:

Then, the first support member and the second support member are respectively positioned and adhesively bonded at the pre-installed positions of the flexible beam through the second positioning portion and the third positioning portion. Therefore, the positioning structure of the flexible beam is simple and easy to operate.
[0015] Further, the second positioning portion includes: an upper left L-shaped plate, an upper left tightening screw, a lower left L-shaped plate, and a lower left tightening screw;
