Considering that the opening degrees of different positions of the landing gear cabin are different, the supporting shaft is connected with the adjusting seat through the joint bearing 3, the mounting seat 2 can be normally mounted, and the auxiliary tool for mounting the landing gear of the airplane is conveniently mounted in the landing gear cabin of the airplane.
As shown in fig. 1 to 3, the supporting shaft includes a first supporting section 4 and a second supporting section 5 connected to the first supporting section 4, the first supporting section 4 and the second supporting section 5 are relatively movable along the axial direction, the first supporting section 4 is connected to one of the adjusting seats, and the second supporting section 5 is connected to the other adjusting seat. Preferably, the first supporting section 4 and the second supporting section 5 are in threaded connection, the first supporting section 4 and the second supporting section 5 are cylinders, the first supporting section 4 and the second supporting section 5 are coaxially arranged, an external thread is arranged at one end of the first supporting section 4, the other end of the first supporting section 4 is connected with one mounting seat 2 through a joint bearing 3, one end of the second supporting section 5 is provided with an internal thread hole which allows the end, provided with the external thread, of the first supporting section 4 to be inserted, and the other end of the second supporting section 5 is connected with the other mounting seat 2 through the joint bearing 3. Through twisting first support section 4 and second support section 5 soon, can realize the regulation of the length of back shaft, and then realize two regulations of adjusting the distance between the seat, and then can adjust the aperture of aircraft landing gear cabin. The supporting shaft is simple in structure, adopts a threaded rotation adjusting mode, has the advantages of good adjusting accuracy, high accuracy and convenience in adjusting and operating, and is beneficial to improving the assembling work efficiency of the aircraft landing gear. Considering that the aircraft landing gear cabin is made of composite materials, due to the uncertainty of the composite materials, the aircraft landing gear mounting auxiliary tool with the structure can be used for the aircraft nose landing gear cabin in different states, and the adaptability is good.
The auxiliary tool for installing the aircraft landing gear with the structure is adopted, and the installation process of the aircraft landing gear comprises the following steps:
s1, installing the landing gear installation auxiliary tool into the landing gear cabin of the airplane, enabling two adjusting seats of the landing gear installation auxiliary tool to be in contact with two opposite inner wall surfaces of the landing gear cabin of the airplane, and adjusting the opening degree of the landing gear cabin of the airplane to a first set value by the landing gear installation auxiliary tool;
s2, trial-assembling the landing gear, and judging whether the opening degree of the landing gear cabin of the airplane meets the requirement;
and S3, after the opening degree of the landing gear cabin meets the requirement, the landing gear is installed in the landing gear cabin.
In the step S1, the opening degree of the landing gear bay is increased by using the aircraft landing gear installation aid, the aircraft landing gear installation aid is adjusted to a proper length, then the aircraft landing gear installation aid is installed in the aircraft landing gear bay by using a tool hammer, two support plates 1 of the aircraft landing gear installation aid are in contact with two opposite inner wall surfaces of the aircraft landing gear bay, at the moment, the two support plates 1 are in a parallel state, the opening degree of the aircraft landing gear bay is increased to a first set value, the first set value is greater than the initial opening degree of the aircraft landing gear bay, and the aircraft landing gear installation aid keeps the current opening degree of the aircraft landing gear bay.
In the step S2, trying to mount the landing gear into the landing gear bay, and if the landing gear cannot be mounted into the landing gear bay, judging that the current opening degree of the landing gear bay cannot meet the requirement, adjusting the opening degree of the landing gear bay again to continuously increase the opening degree of the landing gear bay; if the landing gear can be loaded into the landing gear bay, the current opening of the landing gear bay is determined to be satisfactory, and the next step S3 is executed.
In the above step S2, if the current opening degree of the landing gear bay cannot meet the requirement, when the opening degree of the landing gear bay is increased, the distance between the two adjusting seats is increased by increasing the length of the supporting shaft, that is, by screwing the first supporting section 4 and the second supporting section 5, the distance between the two opposite inner wall surfaces in the landing gear bay is increased, and then the opening degree of the landing gear bay can be increased until the opening degree of the landing gear bay meets the requirement.
After the opening degree of the landing gear bay is adjusted to meet the requirement in step S3, the landing gear may be loaded into the landing gear bay.
The invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-described manner. Various insubstantial improvements are made by adopting the method conception and the technical proposal of the utility model; or without improvement, the above conception and technical solution of the present invention can be directly applied to other occasions, all within the protection scope of the present invention.
