[0018] A cleaning method for an aluminum honeycomb core surface cleaning device, wherein external cleaning water is connected to an input end of a water pump, and an external ultrasonic generator is connected to an ultrasonic transducer. At this time, the inner cavity of a cleaning chamber is filled with cleaning water, and a hollow plate is located above the cleaning chamber. Then, the aluminum honeycomb core is placed on the top of the hollow plate, and then a cylinder is started to drive a linkage rod to descend, thereby driving the hollow plate to move to the bottom of the inner cavity of the cleaning chamber and to be located above a push rod.

[0019] Then, the ultrasonic transducer is used to generate ultrasonic waves to the clean water in the inner cavity of the cleaning chamber to clean the aluminum honeycomb core. During the cleaning process, the oil on the surface of the aluminum honeycomb core falls into the water. After the cleaning is completed, the cylinder is started to drive the hollow plate to rise above the cleaning chamber.

[0020] Then, the motor is started to drive the threaded rod to rotate, and the rotation of the threaded rod drives the movable frame meshed with it to move along the axial direction of the threaded rod and the guide rod, thereby driving the cavity plate to move in the inner cavity of the cleaning bin toward the cylinder.

Then the pressure wheel contacts the top of the aluminum honeycomb core. At this time, the elasticity of the spring assembly causes the pressure wheel and the pressure plate to rise, and the pressure wheel presses the aluminum honeycomb core. At this time, the water pump is started to transport clean water along the telescopic pipe 1, the connecting pipe, and the telescopic pipe 2 to the high-pressure flushing pipe, and then the high-pressure flushing pipe sprays the surface of the aluminum honeycomb core with high pressure, thereby flushing away the debris that may be contaminated on the surface of the aluminum honeycomb core and replenishing the water in the inner cavity of the cleaning bin;

[0022] Then the threaded rod reverses, driving the cavity plate to reset, the moving wheel separates from the straight surface of the inclined plate, the elasticity of the reset spring drives the sealing plate and the moving wheel to reset, and the sealing plate resets to the inside of the cavity plate, so that the clean water in the cleaning chamber cavity is no longer separated, and the supporting spring drives the water blocking head to reset, and the drain pipe is blocked again.

[0023] The beneficial effects of the present invention are as follows:

[0024] After cleaning, the present invention collects the debris and sewage in the inner cavity of the cleaning bin through the filter plate, and discharges this small amount of sewage in a centralized manner, thereby avoiding a large amount of debris in the cleaning water in the inner cavity of the cleaning bin after cleaning a plurality of aluminum honeycomb cores, avoiding the debris from scratching the surface of the aluminum honeycomb core, and only discharging a small amount of sewage, thereby ensuring the cleaning effect without the need for high-frequency water changes, and after cleaning, high-pressure spraying is performed on the surface of the aluminum honeycomb core to avoid some debris remaining on the surface of the aluminum honeycomb core, and to replenish a small amount of clean water lacking in the inner cavity of the cleaning bin.

[0044] The working principle and beneficial effect of the above technical solution are as follows: the external clean water input device is connected to the input end of the water pump 31, and the external ultrasonic generator is connected to the ultrasonic transducer 7. At this time, the inner cavity of the cleaning chamber 1 is filled with clean water, and the hollow plate 53 is located above the cleaning chamber 1;

[0045] The aluminum honeycomb core is placed on the hollow plate 53, and then the cylinder 51 is started to drive the linkage rod 52 to descend, thereby driving the aluminum honeycomb core on the top of the hollow plate 53 to descend to the inner cavity of the cleaning chamber 1, and then ultrasonic waves are generated by the ultrasonic transducer 7, so that the ultrasonic waves act on the cleaning water, and then the aluminum honeycomb core is ultrasonically cleaned. After the cleaning is completed, debris remains in the cleaning water in the inner cavity of the cleaning chamber 1;

[0046] Then, the cylinder 51 is started to drive the linkage rod 52 to rise, thereby driving the hollow plate 53 in the inner cavity of the cleaning chamber 1 to rise, and then the motor 21 is started to drive the threaded rod 22 to rotate. The rotation of the threaded rod 22 drives the movable frame 23 engaged therewith to move along the axis direction of the threaded rod 22 and the guide rod 24 toward the cylinder 51. At this time, the clean water in the inner cavity of the cleaning chamber 1 is filtered by the filter plate 42, so that the debris in the clean water remains on the side of the filter plate 42 close to the cylinder 51;

[0047] And the moving wheel 47 moves in the inner cavity of the moving groove 48. When the moving wheel 47 contacts the inclined surface of the inclined plate 49, the cylinder 51 contacts the push rod 65. As the cavity plate 41 drives the moving wheel 47 to continue to move, the moving wheel 47 moves along the inclined surface of the inclined plate 49 to the straight surface, and the moving wheel 47 moves in the direction of the cavity plate 41, thereby driving the sealing plate 45 to move in the direction of the filter plate 42, and the filter plate 42 is blocked and closed by the sealing plate 45, thereby isolating a small amount of sewage in the inner cavity of the cleaning bin 1 on the side of the cavity plate 41 close to the cylinder 51;

[0048] At this time, the cavity plate 41 pushes the push rod 65 in the direction of the cylinder 51, and then pushes the water blocking head 64 in the direction of the support spring 63. At this time, the support spring 63 is compressed and stored. At this time, the water blocking head 64 leaves the connection between the drain pipe 61 and the control cylinder 62, and then the dirty water isolated by the cavity plate 41 is discharged from the drain pipe 61, thereby achieving the discharge of a small amount of dirty water after the cleaning of an aluminum honeycomb core is completed, thereby avoiding residual debris in the inner cavity of the cleaning chamber 1, impacting the surface of the aluminum honeycomb core during the next cleaning, resulting in scratches on the surface of the aluminum honeycomb core, and avoiding debris affecting the cleaning effect of the aluminum honeycomb core, and only a small amount of water needs to be discharged, and there is no need to frequently replace the clean water in the inner cavity of the cleaning chamber 1, which can also ensure the cleanliness of the clean water in the inner cavity of the cleaning chamber 1.

[0049] Embodiment 2, as Figures 1 to 8 As shown, an embodiment of the present invention provides an aluminum honeycomb core surface cleaning device, the top of the movable frame 23 is fixedly connected to a flushing frame 25, the top of the driving mechanism 2 is provided with a flushing mechanism 3, the flushing mechanism 3 includes a water pump 31, the water pump 31 is fixedly connected to the outside of the cleaning bin 1 and is located below the guide rod 24, the output end of the water pump 31 is fixedly connected to a telescopic tube 1 32, the end of the telescopic tube 1 32 away from the water pump 31 is fixedly connected to a connecting pipe 33, the connecting pipe 33 is fixedly connected to the top of the flushing frame 25, the bottom end of the connecting pipe 33 is fixedly connected to a telescopic tube 2 34, the bottom end of the telescopic tube 2 34 is fixedly connected to a high-pressure flushing pipe 35, a spring assembly 36 is fixedly connected to the bottom of the flushing frame 25, the bottom of the spring assembly 36 is fixedly connected to a pressure plate 37, and the center of the bottom of the pressure plate 37 is fixedly connected to a pressure wheel 38.

[0050] The high-pressure flushing pipe 35 is fixedly connected below the pressing plate 37 and is located on the side of the pressing wheel 38 . The telescopic pipe 2 34 is located between the flushing frame 25 and the pressing plate 37 . The flushing frame 25 is inclined in a direction away from the cavity plate 41 .

[0051] The spring assembly 36 is composed of a damping telescopic rod 361 and a pressing spring 362.

[0052] The working principle and beneficial effect of the above technical solution are as follows: when the hollow plate 53 is located above the cleaning bin 1, it is also located between the flushing rack 25 and the moving rack 23, and the top of the aluminum honeycomb core in the inner cavity of the hollow plate 53 is located on the moving path of the pressure wheel 38. When the threaded rod 22 drives the moving rack 23 to move, the pressure wheel 38 contacts the top of the aluminum honeycomb core. At this time, the elasticity of the Q spring assembly 36 causes the pressure wheel 38 to move and press the aluminum honeycomb core, so that the pressure plate 37 is located near the top of the aluminum honeycomb core, and then the water pump 3 is started. 1 The cleaning water is transported to the high-pressure flushing pipe 35 along the telescopic pipe 1 32, the connecting pipe 33, and the telescopic pipe 2 34, and then the cleaning water is sprayed on the surface and holes of the aluminum honeycomb core by the high-pressure flushing pipe 35. The high-pressure flushing pipe 35 is driven by the moving frame 23 to move, and the aluminum honeycomb core is fully flushed, so that the aluminum honeycomb core is flushed again after the inner cavity of the cleaning chamber 1 is cleaned, so as to prevent the debris of the aluminum honeycomb core from being contaminated on the surface of the aluminum honeycomb core after the inner cavity of the cleaning chamber 1 is cleaned;

[0053] The flushing water flows into the inner cavity of the cleaning chamber 1 to replenish the clean water in the inner cavity of the cleaning chamber 1, thereby realizing that after a small amount of sewage in the inner cavity of the cleaning chamber 1 is discharged, the clean water lacking in the inner cavity of the cleaning chamber 1 can be replenished;

[0054] Then take the aluminum honeycomb core out from the top of the hollow plate 53, and then start the motor 21 to drive the threaded rod 22 to reverse, thereby driving the movable frame 23 to reset. At this time, the cavity plate 41 is separated from the push rod 65, and the support spring 63 releases the thrust after losing the limit to drive the water plugging head 64 to reset, and the drain pipe 61 is blocked again.

[0055] Embodiment 3, a cleaning method of an aluminum honeycomb core surface cleaning device, connecting external cleaning water to the input end of the water pump 31, connecting the external ultrasonic generator to the ultrasonic transducer 7, at this time, the inner cavity of the cleaning chamber 1 is filled with cleaning water, and the hollow plate 53 is located above the cleaning chamber 1, then the aluminum honeycomb core is placed on the top of the hollow plate 53, and then the cylinder 51 is started to drive the linkage rod 52 to descend, thereby driving the hollow plate 53 to move to the bottom of the inner cavity of the cleaning chamber 1 and be located above the push rod 65;

[0056] Then, the ultrasonic transducer 7 generates ultrasonic waves to the cleaning water in the inner cavity of the cleaning chamber 1 to clean the aluminum honeycomb core. During the cleaning process, the oil on the surface of the aluminum honeycomb core falls into the water. After the cleaning is completed, the cylinder 51 is started to drive the hollow plate 53 to rise above the cleaning chamber 1.

[0057] Then, the motor 21 is started to drive the threaded rod 22 to rotate. The rotation of the threaded rod 22 drives the movable frame 23 meshed with it to move along the axis direction of the threaded rod 22 and the guide rod 24, thereby driving the cavity plate 41 to move in the inner cavity of the cleaning chamber 1 toward the cylinder 51. At this time, the clean water in the inner cavity of the cleaning chamber 1 is filtered by the filter plate 42, and the filtered debris is accumulated on the side of the filter plate 42 close to the cylinder 51. At this time, the moving wheel 47 moves in the inner cavity of the moving groove 48. When the cavity plate 41 is about to contact the push rod 65, the moving wheel 47 moves along The inclined surface of the inclined plate 49 moves, and drives the sealing plate 45 to move in the inner cavity of the cavity plate 41. When the cavity plate 41 contacts the straight surface of the inclined plate 49, the sealing plate 45 is driven to block the hollow part of the cavity plate 41. At this time, the inner cavity of the cleaning chamber 1 is separated by the cavity plate 41, and at this time, the cavity plate 41 drives the push rod 65 to move away from the cleaning chamber 1, thereby driving the water plugging head 64 to leave the connection between the drain pipe 61 and the control cylinder 62, and then the dirty water in the inner cavity of the cleaning chamber 1 located on the side of the cavity plate 41 close to the cylinder 51 is discharged from the drain pipe 61;

[0058] When the moving frame 23 moves, it drives the flushing frame 25 to move. At this time, the hollow plate 53 drives the aluminum honeycomb core to be located on the moving path of the pressure wheel 38. Then the pressure wheel 38 contacts the top of the aluminum honeycomb core. At this time, the elasticity of the spring assembly 36 causes the pressure wheel 38 and the pressure plate 37 to rise, and the pressure wheel 38 presses the aluminum honeycomb core. At this time, the water pump 31 is started to transport clean water along the telescopic pipe 1 32, the connecting pipe 33, and the telescopic pipe 2 34 to the high-pressure flushing pipe 35, and then the high-pressure flushing pipe 35 sprays the clean water to the surface of the aluminum honeycomb core under high pressure, thereby flushing away the debris that may be contaminated on the surface of the aluminum honeycomb core and replenishing the water in the inner cavity of the cleaning chamber 1.

[0059] Then the threaded rod 22 reverses, driving the cavity plate 41 to reset, the moving wheel 47 separates from the direct surface of the inclined plate 49, the elasticity of the reset spring 44 drives the sealing plate 45 and the moving wheel 47 to reset, and the sealing plate 45 is reset to the inside of the cavity plate 41, so that the clean water in the inner cavity of the cleaning chamber 1 is no longer separated, and the support spring 63 drives the water blocking head 64 to reset, and the drain pipe 61 is blocked again.

During the cleaning process, oil stains on the surface of the aluminum honeycomb core fall into the water. After the cleaning is completed, the cylinder (51) is started to drive the hollow plate (53) to rise to the top of the cleaning chamber (1); Then, the motor (21) is started to drive the threaded rod (22) to rotate. The rotation of the threaded rod (22) drives the movable frame (23) meshed with the threaded rod (22) to move along the axis of the threaded rod (22) and the guide rod (24), thereby driving the cavity plate (41) to move in the inner cavity of the cleaning chamber (1) toward the cylinder (51). At this time, the clean water in the inner cavity of the cleaning chamber (1) is filtered by the filter plate (42), and the filtered debris is accumulated on the outside of the filter plate (42). At this time, the moving wheel (47) moves in the inner cavity of the moving groove (48). When the cavity plate (41) is about to contact the push rod (65), the moving wheel (47) moves along the inclined plate (4 9), and drives the sealing plate (45) to move in the inner cavity of the cavity plate (41); when the cavity plate (41) contacts the straight surface of the inclined plate (49), the sealing plate (45) is driven to block the hollow portion of the cavity plate (41); at this time, the inner cavity of the cleaning chamber (1) is separated by the cavity plate (41); at this time, the cavity plate (41) drives the push rod (65) to move in a direction away from the cleaning chamber (1), thereby driving the water plugging head (64) away from the connection between the drain pipe (61) and the control cylinder (62), and thereby draining the dirty water in the inner cavity of the cleaning chamber (1) located on the side of the cavity plate (41) close to the cylinder (51) from the drain pipe (61); When the moving frame (23) moves, it drives the flushing frame (25) to move. At this time, the hollow plate (53) drives the aluminum honeycomb core to be located on the moving path of the pressure wheel (38). Then, the pressure wheel (38) contacts the top of the aluminum honeycomb core. At this time, the elasticity of the spring assembly (36) causes the pressure wheel (38) and the pressure plate (37) to rise, and causes the pressure wheel (38) to press the aluminum honeycomb core. At this time, the water pump (31) is started to transport clean water along the telescopic tube 1 (32), the connecting tube (33), and the telescopic tube 2 (34) to the high-pressure flushing pipe (35), and then the clean water is sprayed to the surface of the aluminum honeycomb core through the high-pressure flushing pipe (35), thereby flushing away debris that may be contaminated on the surface of the aluminum honeycomb core and replenishing the water in the inner cavity of the cleaning chamber (1); Then, the threaded rod (22) is reversed, driving the cavity plate (41) to reset, the moving wheel (47) is separated from the straight surface of the inclined plate (49), the elasticity of the reset spring (44) drives the sealing plate (45) and the moving wheel (47) to reset, and the sealing plate (45) is reset to the inside of the cavity plate (41), so that the clean water in the inner cavity of the cleaning chamber (1) is no longer separated, and the support spring (63) drives the water plugging head (64) to reset, and the drainage pipe (61) is blocked again.
