Description

Technical Field

[0001] This invention belongs to the field of aviation component technology, and specifically relates to an aviation component cleaning and drying device. Background Technology

[0002] Aerospace components can be manufactured from metallic materials (stainless steel, magnesium alloys, titanium alloys, aluminum alloys, structural steel, high-temperature alloys, etc.) and non-metallic materials (aerospace ceramics, special ceramics, special rubbers, carbon fiber, etc.). To meet the high strength and weight reduction requirements of aerospace components, titanium alloys, stainless steel, aluminum alloys, and various composite materials are widely used in the manufacture of components such as fuselage reinforcing frames, wing spars, and reinforcing ribs. Since aerospace components are mostly irregularly shaped, after painting, rough areas on the painted surface need to be sanded to ensure a smooth finish. After sanding, residual debris is washed away with water, and finally, the components are placed in a drying oven for drying.

[0003] Traditional aerospace component cleaning processes typically employ fixed high-pressure nozzles to directly spray and remove debris from the workpiece surface. However, aerospace components are often irregularly shaped, which can easily cause debris to accumulate at the bends, making complete removal impossible. After cleaning, the components must be removed and dried using a fan, a complex process with low cleaning and drying efficiency. To address this, this invention proposes an aerospace component cleaning and drying device. Summary of the Invention

[0028] Specifically, the cylinder wall 201 is provided with a plurality of water guiding chambers 205, and a water inlet groove 202 is fixedly connected to the top of the cylinder wall 201. Each water guiding chamber 205 is connected to the water inlet groove 202. A water injection chamber 203 is fixedly connected to the top cover 103. The water inlet groove 202 is rotatably connected to the water injection chamber 203. A high-pressure water pipe 204 is connected to the top of the water injection chamber 203.

[0029] Specifically, the cylinder wall 201 is provided with a plurality of limiting grooves 207, each of which corresponds to a water guiding cavity 205. The outer wall of the inner toothed ring 109 is fixedly connected with a plurality of limiting baffles 206. The water guiding cavity 205, the limiting baffles 206, and the limiting grooves 207 correspond one to one. The limiting baffles 206 are slidably connected to the limiting grooves 207, and the limiting baffles 206 are matched with the water guiding cavity 205.

[0030] Specifically, the cylindrical wall 201 is cylindrical, with its top end rotatably connected to the cavity. A breathable grille 208 is fixedly connected to the cylindrical wall 201. Multiple sets of flushing nozzles 209 are provided inside the cylindrical wall 201, and each set of flushing nozzles 209 communicates with each water guiding cavity 205.

[0031] Specifically, a plurality of fan blades 301 are rotatably connected to the outside of the cylinder wall 201. The fan blades 301 are rotatably connected to the outer wall of the cylinder wall 201 via a rotating shaft. A limiting block 305 is provided on one side of the rotating shaft, and the limiting block 305 is fixedly connected to the cylinder wall 201.

[0032] Specifically, the bottom of the side wall 102 is provided with an air inlet, and a heating grid 306 is provided inside the air inlet. The motor 105 is provided with a control chip, and the control chip is electrically connected to the heating grid 306.

[0033] Specifically, the base 101 is provided with a water guide groove 304, and a drain baffle 303 is fixedly connected to the top of the water guide groove 304. A parts fixing platform 302 is fixedly connected to the upper end of the drain baffle 303.

[0034] The device can be equipped with a crane fixed to the outside of the side wall 102 or a lifting device at the bottom of the base 101 for loading materials.

[0035] Working principle:

[0036] When the device is in use, the operator fixes the workpiece on the part fixing platform 302, and then attaches the side wall 102 to the upper end of the base 101 via a crane and lifting device. At this time, the motor 105 is started to reverse, and the water valve is opened to supply water to the high-pressure water pipe 204. The motor 105 drives the drive gear 106 to reverse. At this time, under the meshing action between the drive gear 106, planetary gear 108, and internal gear ring 109, the internal gear ring 109 rotates clockwise. The clockwise rotation of the internal gear ring 109 drives the limit baffle 206 to rotate clockwise in the limit groove 207. At this time, the water guide chamber in the limit groove 207... When 205 is opened, under the action of the limit baffle 206, the cylinder wall 201 sleeved on the outer end of the inner toothed ring 109 rotates forward. At this time, the fan blades 301 fixed on the outside of the cylinder wall 201 are affected by the forward wind force and rotate inward to retract. At the same time, the water in the high-pressure water pipe 204 enters each rinsing nozzle 209 through the water injection chamber 203, the water inlet trough 202, and the water guide chamber 205. The water is sprayed onto the workpiece through the rinsing nozzles 209. As the cylinder wall 201 rotates, the rinsing nozzles 209 rotate around the workpiece to spray, increasing the cleaning force. After the workpiece is cleaned, the motor 105 and the water valve can be stopped.

[0037] When the device is drying, the motor 105 is started to rotate forward, and the heating grid 306 is energized by the control chip. At this time, the internal gear ring 109 rotates in reverse, which drives the limiting baffle 206 to rotate counterclockwise along the limiting groove 207. At this time, the water guiding cavity 205 is closed under the action of the limiting baffle 206 to prevent leakage of the rinsing nozzle 209 during the drying process. At the same time, the limiting baffle 206 drives the cylinder wall 201 to rotate in reverse. At this time, the fan blades 301 on the outside of the cylinder wall 201 unfold with the rotation and are fixed by the limiting block 305. As the cylinder wall 201 rotates, the fan blades 301 rotate around the axis. Under the action of the fan blades 301, the outside air is heated by the heating grid 306 and enters the cylinder wall 201 through the top ventilation grid 208 to dry the workpiece. Then it is discharged through the bottom water guiding groove 304. The device is cleverly designed, highly automated, and greatly reduces labor costs.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
