Embodiment 1
[0053] Such as figure 1 , figure 2 As shown, the support and fixing device used for the overall delivery of landing gear in the present invention is composed of 10 major parts: eccentric joint assembly 1, anti-rotation pin 2, connecting rod 3 (left thread), left lock nut 4, large nut 5, right Lock nut 6, ear plug connecting rod assembly 7 (right thread), positioning piece assembly 8, U-shaped clamp assembly 9, connecting pin 10, and one end of eccentric joint assembly 1 is connected to connecting rod 3, large nut 5, ear Insert the connecting rod assembly 7, the positioning piece assembly 8, and the U-shaped clip assembly 9. The anti-rotation pin 2 is inserted into the connecting rod 3 through the eccentric joint assembly 1 to connect the eccentric joint assembly 1 and the connecting rod 3 into one body, and the connecting rod 3 will not rotate in the eccentric joint assembly 1 during operation. The two ends of the large nut 5 are respectively provided with a left lock nut 4...

A support fixing device for integral delivery of a landing gear and a use method are disclosed. The support fixing device comprises an eccentric joint assembly (1), one end of the eccentric joint assembly is provided with a first mounting hole (11) for connecting with a small rocker arm mounting hole of the landing gear, the other end of the eccentric joint assembly is provided with a connecting hole (12), and one end of a connecting rod (3) is inserted into the connecting hole to be fixedly connected with the eccentric joint assembly; the other end of the connecting rod (3) is connected withone end of a large nut (5) through threads, and the other end of the large nut (5) is connected with a lug insertion connecting rod assembly (7) through threads; a positioning member assembly (8) is encircled on the lug insertion connecting rod assembly, and the positioning member assembly (8) is hinged to a U-shaped clamp assembly (9); the U-shaped clamp assembly includes a U-shaped clamp (91) arranged across the top surface of a landing gear rear support, as well as a front pressing screw (92) and a back pressing screw (96) used for pressing the landing gear rear support.
Description
technical field [0001] The invention relates to an aircraft landing gear, in particular to a supporting and fixing device and a using method for integral delivery of the landing gear. Background technique [0002] Before a landing gear is delivered to the main engine factory for final assembly, all components (including hydraulic system components, electrical control system components, and pneumatic system control components) need to be installed in the assembly plant. When installing the system components, install the system components in place under a fully simulated landing gear installation attitude; at this time, in order to simulate the landing gear installation attitude, the supports used to support the small rocker arm and rear bracket of the landing gear are simple wooden structures and cannot be adjusted length. After all the system components are installed in place, they need to be inspected and accepted by the military representative, and then with the consent o...
