Description

Technical Field

[0001] This utility model relates to the field of oil removal and cleaning technology for aerospace components, and in particular to an oil removal and cleaning device for aerospace components. Background Technology

[0002] Aerospace vehicles are composed of components assembled in an orderly manner. During the processing or assembly of aerospace components, degreasing treatment is required to reduce the impact of oil contamination during processing or assembly, which could affect processing accuracy or post-assembly working condition.

[0003] Currently, the main method for degreasing aerospace components is immersion washing. Alkaline degreasing solutions are used to remove oil stains through saponification (for animal and vegetable oils) and emulsification (for mineral oils). However, when aerospace components (such as engine blades, pipe joints, and gearbox parts) are immersed in a cleaning tank containing alkaline degreasing solutions, some components have complex structures with numerous precision gaps, blind holes, and threaded grooves. When these components are left to stand in the cleaning tank, the oil stains in these areas are difficult to be fully wetted by the solution due to space constraints, easily forming "dead zones." Therefore, there is a problem of incomplete degreasing during immersion. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an oil removal and cleaning device for aerospace components, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An aerospace component degreasing and cleaning device includes:

[0007] A cleaning tank having a cleaning chamber filled with a degreasing and cleaning fluid for aerospace components;

[0008] A rotating drum is rotatably mounted on the inner wall of the cleaning chamber, and has a first mounting cavity and a second mounting cavity, which are connected to each other.

[0009] A lifting assembly is disposed in the first and second mounting cavities of the rotating drum, and the lifting assembly is configured to be adjustable in height.

[0010] Four placement cylinder assemblies, mounted on the lifting assembly, are used to store aerospace parts. The height of the four placement cylinder assemblies can be adjusted by the lifting assembly, and the four placement cylinder assemblies can be driven by a rotating cylinder to reciprocate, so that the aerospace parts stored in the placement cylinder assemblies are fully immersed in the degreasing and cleaning fluid in the cleaning chamber.

[0011] Preferably, a motor is fixedly installed on the bottom side of the cleaning tub, and the output shaft of the motor extends into the cleaning chamber and is installed on the bottom side of the rotating drum.

[0012] Preferably, the lifting assembly includes:

[0013] The first mounting plate is movably installed in the first mounting cavity of the rotating drum. The first mounting plate is arranged in a cross shape and is adapted to the first mounting cavity.

[0014] The second mounting plate is movably installed in the second mounting cavity of the rotating drum. The second mounting plate is arranged in a cross shape and is adapted to the second mounting cavity.

[0015] A connecting rod is fixedly installed on the side of the first mounting plate and the second mounting plate that are close to each other;

[0016] An electric actuator is fixedly installed on the top inner wall of the second mounting cavity, and its output end is fixedly installed on the top side of the second mounting plate.

[0017] Preferably, the placement cylinder assembly includes:

[0018] A cleaning cylinder is fixedly installed at one end of a first mounting plate, and its inner wall has threaded grooves.

[0019] The cylinder cover is threaded into the threaded groove of the cleaning cylinder.

[0020] Preferably, a handle is fixedly installed on the top side of the cylinder cover. The handle consists of a rod body and a handle plate, and the liquid level in the cleaning chamber reaches half the height of the rod body on the handle.

[0021] Preferably, a plurality of bottom cylinders are fixedly installed on the bottom side of the cleaning cylinder, and the bottom side of the bottom cylinder has a bottom cavity. A ball bearing is rolled inside the bottom cavity of the bottom cylinder, and the bottom contact surface of the ball bearing abuts against the bottom inner wall of the cleaning cavity.

[0022] Preferably, a drain pipe is provided on the bottom side of the cleaning tank, the drain pipe is connected to the cleaning chamber, and a valve is provided on the drain pipe.

[0023] This application involves placing multiple aerospace components into corresponding cleaning cylinders. The cylinder caps are then screwed into the threaded grooves of the cleaning cylinders using a handle to prevent the components from floating out during immersion. An electric actuator is then activated, causing the first mounting plate to immerse the multiple cleaning cylinders containing the aerospace components into the degreasing cleaning solution within the cleaning chamber of the cleaning tank. The degreasing cleaning solution enters the cleaning cylinders through the cylinder holes, performing an immersion degreasing operation on the aerospace components. Simultaneously, a drive motor causes the rotating drum to oscillate within the cleaning chamber, causing the four cleaning cylinders on the first mounting plate to reciprocate around the axis of the rotating drum at a 120° angle. During the reciprocating placement process, relative motion occurs between the aerospace components and the degreasing cleaning fluid. This motion directly washes the outer surface of the aerospace components, promoting full contact and reaction between the degreasing cleaning fluid and the outer surface of the components. This accelerates the decomposition and removal of oil stains from the surface of the aerospace components. At the same time, the reciprocating oscillation causes the degreasing cleaning fluid to flow within the gaps of the aerospace components, forming local eddies that flush out oil stains hidden deep within the gaps of the aerospace components. This achieves thorough immersion and degreasing of the aerospace components. Furthermore, this application can simultaneously degrease and clean multiple aerospace components, improving the efficiency of the degreasing and cleaning work. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] To address the problem that existing aerospace components, often with complex structures such as numerous precision gaps, blind holes, and threaded grooves, cannot be fully immersed in an alkaline degreasing solution when placed in the cleaning tank, resulting in "dead zones" and incomplete degreasing, this embodiment discloses an aerospace component degreasing and cleaning device including, as follows: Figure 1 The washing tub 100 and the rotating drum 200 are shown; as Figure 4 The lifting assembly 300 and the four placement cylinder assemblies 400 are shown.

[0033] like Figure 2 As shown, the cleaning tub 100 has a cleaning chamber 101 inside, and the rotating drum 200 is rotatably mounted on the inner wall of the cleaning chamber 101; a motor 203 is fixedly installed on the bottom side of the cleaning tub 100, and the output shaft of the motor 203 extends into the cleaning chamber 101 and is installed on the bottom side of the rotating drum 200; by starting the motor 203, the rotating drum 200 can be driven to reciprocate within the cleaning chamber 101.

[0034] like Figure 3 and Figure 4As shown, for the installation of the lifting assembly 300, the rotating drum 200 has a first mounting cavity 201 and a second mounting cavity 202, which are connected. The lifting assembly 300 is disposed in the first mounting cavity 201 and the second mounting cavity 202 of the rotating drum 200, and the lifting assembly 300 is configured to be adjustable in height. The lifting assembly 300 includes: a first mounting plate 301, a second mounting plate 302, a connecting rod 303, and an electric push rod 304. The first mounting plate 301 is movably installed in the first mounting cavity 201 of the rotating drum 200, and the first mounting plate 301 is arranged in a cross-shaped structure. Mounting plate 301 is adapted to the first mounting cavity 201; the second mounting plate 302 is movably installed in the second mounting cavity 202 of the rotating drum 200, the second mounting plate 302 is arranged in a cross shape, and the second mounting plate 302 is adapted to the second mounting cavity 202; the connecting rod 303 is fixedly installed on the side of the first mounting plate 301 and the second mounting plate 302 that are close to each other; the electric push rod 304 is fixedly installed on the top inner wall of the second mounting cavity 202, and its output end is fixedly installed on the top side of the second mounting plate 302; by activating the electric push rod 304, the second mounting plate 302 can drive the connecting rod 303 and the first mounting plate 301 to move up or down.

[0035] like Figure 4 As shown, four placement cylinder assemblies 400 are mounted on the lifting assembly 300 for storing aerospace parts. The height of the four placement cylinder assemblies 400 can be adjusted by the lifting assembly 300, and the four placement cylinder assemblies 400 can be driven by the rotating cylinder 200 to reciprocate. Each placement cylinder assembly 400 includes a cleaning cylinder 401 and a cylinder cover 402. The cleaning cylinder 401 is fixedly mounted on one end of the first mounting plate 301, and its inner wall has a threaded groove 4011. The cleaning cylinder 401 is used to store aerospace parts. The cylinder cover 402 is threaded into the threaded groove 4011 of the cleaning cylinder 401 to prevent the aerospace parts stored in the cleaning cylinder 401 from floating out of the cleaning cylinder 401 during the soaking process.

[0036] like Figure 2 and Figure 4 As shown, a handle 4021 is fixedly installed on the top side of the cylinder cover 402. The handle 4021 consists of a rod and a handle disc. At the same time, the cleaning chamber 101 is filled with degreasing and cleaning fluid for aerospace parts. The liquid level in the cleaning chamber 101 reaches half the height of the rod on the handle 4021, so as to achieve degreasing and soaking of the aerospace parts stored in the cleaning cylinder 401.

[0037] like Figure 5 and Figure 6As shown, multiple bottom cylinders 403 are fixedly installed on the bottom side of the cleaning cylinder 401. The bottom side of the bottom cylinder 403 has a bottom cavity 4031. The cross-section of the bottom cavity 4031 is larger than that of a semicircle. Rolling balls 404 are rolled inside the bottom cavity 4031 of the bottom cylinder 403 to prevent the rolling balls 404 from detaching from the bottom cavity 4031 of the bottom cylinder 403. The bottom contact surface of the rolling balls 404 abuts against the bottom inner wall of the cleaning chamber 101. When the first mounting plate 301 drives the cleaning cylinder 401 to reciprocate, the multiple rolling balls 404 on the bottom side of the cleaning cylinder 401 roll on the bottom inner wall of the cleaning chamber 101, which facilitates the deflection and swing of the cleaning cylinder 401 when it reciprocates on the bottom inner wall of the cleaning chamber 101.

[0038] like Figure 2 As shown, a drain pipe 102 is provided on the bottom side of the cleaning tank 100. The drain pipe 102 is connected to the cleaning chamber 101. A valve 1021 is provided on the drain pipe 102. By opening the valve 1021, the cleaning liquid after degreasing and cleaning in the cleaning chamber 101 of the cleaning tank 100 can be discharged.

[0039] This application places multiple aerospace components into corresponding cleaning cylinders 401. The cylinder cover 402 is then screwed onto the threaded groove 4011 of the cleaning cylinder 401 using the handle 4021. This prevents the aerospace components from floating out of the cleaning cylinder 401 during immersion. Then, the electric push rod 304 is activated, causing the first mounting plate 301 to immerse the multiple cleaning cylinders 401 containing the aerospace components into the degreasing cleaning solution in the cleaning chamber 101 of the cleaning tank 100. The degreasing cleaning solution enters the cleaning cylinder 401 through the cylinder holes, performing an immersion degreasing operation on the aerospace components. At this time, the drive motor 203 drives the rotating drum 200 to swing within the cleaning chamber 101, causing the four cleaning cylinders on the first mounting plate 301 to... The cylinder 401 reciprocates around the axis of the rotating cylinder 200 with a deflection angle of 120°. During the reciprocating motion, relative motion occurs between the aerospace components and the degreasing cleaning fluid, which can directly wash the outer surface of the aerospace components. This promotes full contact and reaction between the degreasing cleaning fluid and the outer surface of the aerospace components, accelerating the decomposition and peeling of oil stains on the surface of the aerospace components. At the same time, the reciprocating motion can cause the degreasing cleaning fluid to flow in the gaps of the aerospace components, forming local eddies, which wash out the dead corner oil stains hidden deep in the gaps of the aerospace components. This can achieve thorough soaking and degreasing of the aerospace components. In addition, this application can realize simultaneous degreasing and cleaning of multiple aerospace components, improving the efficiency of degreasing and cleaning of aerospace components.
