Description

Technical Field

[0001] The present invention relates to the technical field of aircraft component repair, and particularly to a mode conversion valve disassembly and assembly component for repairing an inboard spoiler actuator of an aircraft and a usage method thereof. Background Art

[0002] The inboard spoiler actuator is installed on the wing part of the aircraft. Its function is to cooperate with the ailerons to adjust the aircraft attitude in the air and play a role in decelerating when the aircraft lands. The mode conversion valve in the inboard spoiler actuator is installed in the valve hole of the housing, and its function is to control the telescopic movement of the actuator.

[0003] When repairing the inboard spoiler actuator, it is necessary to disassemble the mode conversion valve. After inspection, replace the seal and then install it into the valve hole for testing and leaving the factory. However, currently, when disassembling and assembling the mode conversion valve, since it is a slender cylindrical part with small size, small clearance, and large frictional force of the sealing ring,

[0004] it is extremely laborious to take out, with low efficiency. And during the disassembly and assembly process, when the parts of the valve are unevenly stressed, it is easy to cause scratches inside the valve hole. Once the inside of the valve hole is scratched, the housing needs to be replaced, which will cause great economic losses. For this reason, we propose a mode conversion valve disassembly and assembly component for repairing an inboard spoiler actuator of an aircraft and a usage method thereof. Summary of the Invention

[0005] The purpose of the present invention is to provide a mode conversion valve disassembly and assembly component for repairing an inboard spoiler actuator of an aircraft and a usage method thereof, so as to solve the problems raised in the above background art.

[0006] A mode conversion valve disassembly and assembly component for repairing an inboard spoiler actuator of an aircraft and a usage method thereof include a housing, a pulling tool, a pulling sleeve device, and an assembly device. The pulling tool includes a long rod hook. The upper end of the long rod hook is movably connected with a long strip-shaped handle. The lower end of the long rod hook is inserted into the inside of the mode conversion valve in the valve hole of the housing, and the hook head at the lower end of the long rod hook is inserted into the obliquely upward valve hole arranged on the inner side surface of the mode conversion valve. A centering slider is slidably sleeved on the long rod hook. The small-diameter part at the lower end of the centering slider is inserted into the upper end of the mode conversion valve, and the small-diameter part at the lower end of the centering slider is the same as the inner diameter of the mode conversion valve. The pulling sleeve device includes an externally threaded support sleeve. The externally threaded support sleeve is sleeved outside the centering slider. The lower end of the externally threaded support sleeve is connected to the surface of the housing. The externally threaded support sleeve is externally threaded and connected with an internally threaded pulling sleeve. A plain bearing is arranged at the upper end of the internally threaded pulling sleeve. The upper end of the plain bearing is connected with a positioning sleeve. A square through groove with a length and width larger than the handle is opened in the center of the positioning sleeve. A first positioning groove perpendicular to and intersecting with the square through groove in the horizontal plane angle is opened in the center of the upper surface of the positioning sleeve, and the length and width of the first positioning groove are the same as those of the handle.

[0007] The assembly device includes a pressure rod, the diameter of the pressure rod is larger than that of the mode conversion valve, a pressure head is installed at the upper end of the pressure rod, a centering sleeve is sleeved outside the pressure rod, a protruding positioning part is arranged at the lower end of the centering sleeve, the protruding positioning part is inserted into an annular groove arranged at the opening position of the valve hole, a second positioning groove is opened at the lower end of the pressure rod, a positioning rod head is inserted into the second positioning groove, and a positioning rod at the lower end of the positioning rod head is inserted into the upper end of the mode conversion valve.

[0008] Preferably, a support sleeve positioning hole is vertically opened at the lower end of the external thread support sleeve, a housing positioning hole is arranged on the housing surface at the lower end of the support sleeve positioning hole, a positioning pin is inserted into the support sleeve positioning hole and the housing positioning hole, and the external thread support sleeve and the positioning pin are connected and fixed through the positioning pin.

[0009] Preferably, the pressure head, the positioning rod head and the positioning rod are made of nylon material, which plays a protective role during the installation process of the mode conversion valve.

[0010] Another technical problem to be solved by the present invention is to provide a usage method of a mode conversion valve disassembly and assembly component for repairing an inboard spoiler actuator of an aircraft, including the following steps:

[0011] When removing the mode conversion valve from the valve hole of the housing:

[0012] S1: Install the extractor, insert the hook head of the long rod hook into the valve hole of the mode conversion valve, and then slide the small-diameter part at the lower end of the centering slider downward along the long rod hook and insert it into the upper end of the mode conversion valve to fix the position of the long rod hook;

[0013] S2: Install the pull sleeve device, insert the external thread support sleeve outside the centering slider, and at the same time, make the handle pass through the square through groove;

[0014] S3: Rotate the handle so that the handle is directly above the first positioning groove;

[0015] S4: Rotate the internal thread pull sleeve to move upward, and further make the positioning sleeve move upward, so that the handle is inserted into the first positioning groove for positioning. Since the positioning sleeve can rotate relative to the upper part of the internal thread pull sleeve through a plain bearing, the positioning sleeve moves vertically upward after being connected to the handle, and drives the extractor and the mode conversion valve as a whole to move upward through the handle, and pulls out the mode conversion valve from the valve hole.

[0016] When installing the mode conversion valve into the valve hole of the housing:

[0017] S5: Align the mode conversion valve and place it above the valve hole of the housing, and then insert the positioning rod below the positioning rod head into the upper part of the mode conversion valve;

[0018] S6: Place the centering sleeve over the mode conversion valve and insert the protruding positioning portion into the annular groove to fix the position of the centering sleeve.

[0019] S7: Insert the pressure rod into the centering sleeve so that the second positioning groove is inserted outside the positioning rod head.

[0020] S8: Push down the pressure head forcefully so that the pressure rod presses the mode conversion valve into the valve hole through the positioning rod head and the positioning rod.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The present invention can make the connection between the extractor and the mode conversion valve firm, so that it is convenient and fast for the sleeve extraction device to drive the extractor and the mode conversion valve to move upward. Moreover, the mode conversion valve is uniformly stressed and will not damage the inner wall of the valve hole, thus affecting the repair.

[0023] During installation, the mode conversion valve is evenly stressed and stably moved downward through the assembly device until it is inserted into the valve hole.

[0024] The present invention has a delicate structure and is used in cooperation with multiple structures on the inner spoiler actuator cylinder, with strong structural stability. By using the present invention, the disassembly and assembly efficiency of the mode conversion valve and the safety during the disassembly and assembly process are greatly improved, which can effectively improve the maintenance quality and efficiency and increase the production efficiency of the enterprise.
