Description

Technical Field

[0001] The utility model relates to the technical field of assembly and debugging of aircraft electromechanical systems, in particular to a device for disassembling and installing an aircraft hydraulic oil filter. Background Art

[0002] After the aircraft is assembled and before it is qualified for commissioning, the filter elements of the electromechanical system's pressure oil filter and return oil filter must be replaced. Due to the internal sealing of the oil filter, the preload force of the oil filter is relatively large; furthermore, the space where the oil filter is located is relatively small, and the effective force arm of the conventional wrench distributed during use is relatively small. When disassembling and installing the oil filter, there are problems such as high labor intensity, long working hours, and low work efficiency. Considering the use of an extension rod for the wrench, due to the small installation space of the oil filter, although the force arm of the extension rod meets the requirements, during operation, the extension rod often collides with the body structure, the working angle is small, and multiple repeated actions are required, the working time is long, and the work efficiency is also low. In order to reduce labor intensity and improve work efficiency, it is urgent to propose improvement measures to improve on-site production conditions. Utility Model Content

[0003] In order to solve the above problems, the utility model provides an aircraft hydraulic oil filter disassembly and installation device.

[0004] The invention discloses a disassembly and installation device for an aircraft hydraulic oil filter, comprising a turntable, a rotating sleeve head connected to the turntable, a force transmission arm matched with the rotating sleeve head, and a telescopic handle hinged with the turntable through a pin.

[0005] As a further improvement of the utility model, the rotating sleeve head is provided with an inner hexagonal groove, and the working surface of the inner hexagonal groove matches with the hexagonal boss surface at the bottom of the oil filter.

[0006] As a further improvement of the utility model, the rotating sleeve head is provided with a plurality of groups of spaced tooth blocks for rotating the force transmission arm and changing the working direction.

[0007] The beneficial effects of the utility model are: compared with directly using a wrench to operate, it expands the working space, protects the disassembly and installation boss of the oil filter, reduces the labor intensity of the operator, improves work efficiency, shortens the operation time, and greatly reduces the safety and quality risks of the product.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0017] like Figures 1 to 5 As shown, an aircraft hydraulic oil filter disassembly and installation device includes a turntable 3, a rotating sleeve head 1 connected to the turntable 3, a force transmission arm 2 matched with the rotating sleeve head 1, and a telescopic handle 4 hinged to the turntable 3 through a pin 5.

[0018] The turntable 3 is provided with a cylindrical protrusion, and the rotary sleeve head 1 can rotate around the cylindrical protrusion.

[0019] Compared with working directly with a wrench, the working space is expanded, the disassembly and installation boss 21 of the oil filter are protected, the labor intensity of the operator is reduced, the work efficiency is improved, the working time is shortened, and the safety and quality risks of the product are greatly reduced.

[0020] The rotating socket head 1 is provided with an inner hexagonal groove 11, and the working surface of the inner hexagonal groove cooperates with the hexagonal boss surface at the bottom of the oil filter. Compared with the ordinary wrench, the contact working surface is increased. In addition to meeting the basic requirements of disassembly and installation, it can also protect the hexagonal boss of the oil filter and extend the service life. During use, the force is transmitted to the force transmission arm 2 on the turntable 3 through the telescopic handle 4, and the force transmission arm 2 drives the rotating socket head 1 to rotate, directly drives the oil filter to rotate, and achieves the operation purpose.

[0021] The rotating sleeve head 1 is provided with a plurality of groups of spaced tooth blocks 12 for rotating the force transmission arm 2 and changing the working direction. The spaced tooth blocks 12 are arranged equidistantly according to the outer cylindrical surface of the rotating sleeve head 1 .

[0022] The turntable 3 is hinged to the force transmission arm 2 via a pin 6 , and the function of the turntable 3 is to realize the reciprocating motion of the telescopic handle 4 .

[0023] The telescopic handle 4 can rotate on the turntable 3 to change the working angle, avoid a narrow working space, and expand the working space. In addition, the telescopic handle 4 can increase the effective working arm, thereby reducing labor intensity.

[0024] The operation process is divided into two processes: disassembly and installation, as follows:

[0025] The disassembly steps are as follows:

[0026] Disassembly step 1: Place the rotating sleeve head 1 of the device in the space where the oil filter is installed;

[0027] Disassembly step 2: Rotate the force transmission arm 2 in the clockwise direction;

[0028] Disassembly step 3: Adjust the handle angle and length of the telescopic handle 4 to select a position suitable for the working space;

[0029] Disassembly step 4: Apply force to the telescopic handle 4 in the clockwise direction to drive the oil filter to rotate through the turntable 3, the force transmission arm 2 and the rotating sleeve head 1; after rotating a certain angle, rotate the telescopic handle 4 counterclockwise, at this time the oil filter does not move, and the force transmission arm follows the movement; after rotating a certain angle, the force transmission arm 2 cooperates with the spacer tooth block 12 of the rotating sleeve head 1 to achieve arc-shaped reciprocating motion;

[0030] Disassembly step 5: Remove the oil filter and replace the filter element.

[0031] The installation steps are as follows:

[0032] Installation step 1: Place the rotating sleeve head 1 of the device in the space where the oil filter is installed;

[0033] Installation step 2: Rotate the force transmission arm 2 in the counterclockwise direction;

[0034] Installation step 3: Adjust the handle angle and length of the telescopic handle 4 and select a position suitable for the working space;

[0035] Installation step 4: Apply force to the telescopic handle 4 in the counterclockwise direction, and drive the oil filter to rotate through the turntable 3, the force transmission arm 2 and the rotating sleeve head 1; after rotating a certain angle, rotate the telescopic handle 4 clockwise, at this time the oil filter does not move, and the force transmission arm follows the movement; after rotating a certain angle, the force transmission arm 2 cooperates with the spacer tooth block 12 of the rotating sleeve head 1 to achieve arc-shaped reciprocating motion;

[0036] Installation step 5: Installation completed, check.

[0037] The force transmission arm 2 is provided with a boss 21 which cooperates with the spaced tooth block 12 of the rotating sleeve head 1 to transmit the force on the turntable 3 to the rotating sleeve head 1; by rotating, the force transmission arm 2 can change the working direction to realize the disassembly and installation functions of the oil filter.
