Description

Technical Field

[0001] This utility model relates to the field of parts cleaning technology, and in particular to a rapid parts cleaning device for aerospace parts processing. Background Technology

[0002] In the process of aerospace assembly, machined parts are required. After prolonged use, the surface of these parts often accumulates contaminants such as metal oxides, oil stains, and solid dirt. Failure to clean them in time will affect the use of the equipment and damage the lifespan of the parts. In the field of precision machinery, it may even affect the accuracy. Therefore, it is necessary to clean the machined parts before use to ensure that the aerospace machined parts are clean and tidy, so as to achieve better installation results.

[0003] A search of existing Chinese patent technology reveals a "cleaning tank for pickling titanium alloy parts for aerospace applications," with publication number "CN218262761U." This device can drive a mesh circular placement frame to rotate, thereby enabling a more comprehensive cleaning of the outer surface of the parts through high-pressure water nozzles, improving the device's working efficiency and shortening the cleaning time. However, after cleaning the workpiece, the surface liquid still needs to be removed. Since the liquid is in full contact with the workpiece surface, the water stains on the surface of each part need to be wiped dry one by one, which will reduce the efficiency of the part cleaning work. Utility Model Content

[0004] Therefore, it is necessary to remove surface liquid after cleaning the workpiece. Since the liquid is in full contact with the workpiece surface, the water stains on the surface of each part need to be wiped dry one by one, which will reduce the efficiency of the part cleaning work. To address this issue, a rapid cleaning device for aerospace parts processing is provided, comprising: an ultrasonic cleaner with a cleaning tank embedded inside; a cleaning mechanism installed at the upper end of the ultrasonic cleaner, the surface of the cleaning mechanism extending into the interior of the cleaning tank; wherein, the cleaning mechanism includes a control component installed at the upper end of the ultrasonic cleaner, one end of the control component is connected to a servo motor, the lower end of the control component extends into the interior of the cleaning tank, and a uniform cleaning component is connected to the surface of the control component, the uniform cleaning component being located inside the cleaning tank.

[0005] In one embodiment, the uniform cleaning component includes an outer rigid metal mesh connected to the surface of the control component. Rings are fixedly connected to the surface of the outer rigid metal mesh near its ends. An isolation frame is disposed inside the outer rigid metal mesh, and a non-woven fabric is disposed inside the isolation frame. An inner mesh is disposed inside the non-woven fabric, and spiral blades are fixedly connected to the inner wall of the inner mesh. Parts to be cleaned are placed between the non-woven fabric and the inner mesh. Fillers or separators can be provided to prevent violent collisions between the parts. The inner mesh is a rigid plastic mesh with good toughness, which can prevent significant deformation when supporting the parts. The operator can manually squeeze the inner mesh to deform it. Two positioning bolts are threaded to the inner wall of the inner mesh, and the ends of these positioning bolts abut against the inner wall of the outer rigid metal mesh to form a connection limit.

[0006] In one embodiment, the control assembly includes two mounting bases fixedly connected to the upper end of the ultrasonic cleaner. A rotating column is rotatably connected to the inner wall of the mounting base. A connecting frame is fixedly connected to the lower end of the rotating column. A collar is fixedly connected to the lower end of the connecting frame. The inner wall of the collar is rotatably connected to the surface of the ring.

[0007] In one embodiment, a connecting plate is fixedly connected to the inner wall of the outer metal mesh near the servo motor, and two locking holes are provided on one side of the connecting plate.

[0008] In one embodiment, two locking blocks are fixedly connected to the end of the isolation frame near the connecting plate, and the locking blocks engage with the inner wall of the adjacent locking hole.

[0009] In one embodiment, the rotating column has an inner groove at its end near the servo motor. A rotating shaft is rotatably connected to the inner wall of the groove, and one end of the rotating shaft is fixedly connected to the output shaft of the servo motor. The servo motor drives the rotating shaft to rotate accordingly.

[0010] In one embodiment, pulleys are fixedly connected to both the rotating shaft and the surface of the uniform cleaning component, and a transmission belt is fitted onto the surface of the two pulleys. The transmission belt causes the lower pulley to drive the connecting plate to rotate synchronously, and the connecting plate drives the outer metal mesh and the isolation frame to rotate synchronously.

[0011] Beneficial effects

[0012] The aforementioned rapid cleaning device for aerospace parts processing, by setting up uniform cleaning components, can reduce the accumulation of impurities on the workpiece surface while the outer metal mesh is in the liquid and the cleaning tank is in operation. When the cleaning tank is stationary in the liquid, the outer metal mesh is rotated rapidly to discharge the impurities mixed with the liquid inside the outer metal mesh to the outside. After the outer metal mesh is cleaned, the rapid rotation of the outer metal mesh can improve the removal efficiency of moisture from the workpiece surface and speed up the cleaning efficiency of the parts.

[0013] By setting up a servo motor and control components, the servo motor drives the rotating shaft to rotate. The upper pulley rotates with the rotating shaft, and through the transmission belt, the lower pulley drives the connecting plate to rotate synchronously. The connecting plate drives the outer metal mesh and the isolation frame to rotate synchronously. Attached Figure Description

[0027] The following is combined Figures 1-5 This invention describes a rapid cleaning device for aerospace parts processing.

[0028] In one embodiment, a rapid cleaning device for aerospace parts processing includes: an ultrasonic cleaner 1, with a cleaning tank 2 embedded inside the ultrasonic cleaner 1; and a cleaning mechanism 3, which is mounted on the upper end of the ultrasonic cleaner 1 and extends into the interior of the cleaning tank 2. The cleaning mechanism 3 includes a control component 32 mounted on the upper end of the ultrasonic cleaner 1, one end of which is connected to a servo motor 33, the lower end of which extends into the interior of the cleaning tank 2, and a uniform cleaning component 31 connected to the surface of the control component 32, the uniform cleaning component 31 being located inside the cleaning tank 2.

[0029] It should be noted that: the ultrasonic cleaner 1 is equipped with a piezoelectric transducer, which is located at the bottom of the cleaning tank 2. It is the core vibration source of ultrasonic cleaning, which converts electrical energy into high-frequency mechanical vibration, usually 20-40kHz. This vibration is directly transmitted to the liquid medium through the metal wall of the cleaning tank 2, forming the basic carrier for ultrasonic wave propagation. The cleaning tank 2 is the core vibration component, and the amplitude and frequency of the vibration directly affect the cleaning effect. The rigid design of the cleaning tank 2 ensures efficient transmission of vibration energy and avoids energy loss.

[0030] like Figure 1-4 As shown, the uniform cleaning component 31 includes an outer metal rigid mesh 311 connected to the surface of the control component 32. Rings 312 are fixedly connected to the surface of the outer metal rigid mesh 311 near its end. An isolation frame 313 is provided inside the outer metal rigid mesh 311. Non-woven fabric 314 is provided on the inner side of the isolation frame 313. An inner mesh 315 is provided inside the non-woven fabric 314. Spiral blades 316 are fixedly connected to the inner wall of the inner mesh 315. A connecting plate 317 is fixedly connected to the inner wall of the outer metal rigid mesh 311 near the servo motor 33. Two locking holes 3171 are opened on one side of the connecting plate 317. Two locking blocks 3131 are fixedly connected to the end of the isolation frame 313 near the connecting plate 317. The locking blocks 3131 engage with the inner wall of the adjacent locking holes 3171.

[0031] In this embodiment, the isolation frame 313 supports the non-woven fabric 314 and works with the inner net 315 to keep the non-woven fabric 314 in a ring shape. The parts to be cleaned are placed between the non-woven fabric 314 and the inner net 315. Fillers or separators can be set to ensure that the parts do not collide violently. The isolation frame 313 divides the parts into multiple ring-shaped areas, and the parts are evenly distributed in the ring area. The inner net 315 is a hard plastic mesh with good toughness, which can keep it from deforming when supporting the parts. The operator can manually squeeze to deform the inner net 315. The inner wall of the inner net 315 is threaded with two positioning bolts. The end of the positioning bolts abuts against the inner wall of the outer metal hard mesh 311 to form a connection limit.

[0032] When the cleaning tank 2 is working, the outer metal mesh 311 can be slowly rotated to make the parts inside the annular area more uniformly cleaned, reducing the accumulation of impurities that fall off the parts and accumulate on the surface of the parts below. The outer metal mesh 311 in the cleaning liquid can also be quickly rotated in the standby state of the cleaning tank 2. At this time, the positioning bolt and the inner mesh 315 drive the spiral blades 316 to rotate, thereby guiding the impurities in the cleaning liquid in the outer metal mesh 311 to the outside. The non-woven fabric 314 can form an auxiliary filter for some impurities. The cleaning liquid moves through the surface of the outer metal mesh 311 into the interior of the inner mesh 315 and is discharged to the outside through the spiral blades 316. The impurities on the surface of the workpiece are discharged to the outside along with the liquid. When the liquid comes into contact with the surface of the part through the outer metal mesh 311, the non-woven fabric 314 forms an auxiliary filtration effect. The non-woven fabric 314 can be removed or replaced according to the cleaning needs and cleaning effect of the parts. The specific adjustment should be made according to the actual use effect.

[0033] After cleaning, the outer metal mesh 311 can be moved out of the liquid. While ensuring that the parts are not damaged, the outer metal mesh 311 can be rotated relatively quickly. At this time, the parts located on the non-woven fabric 314 and the inner mesh 315 will rotate accordingly. During the rotation, the liquid on the surface of the parts can be thrown out by centrifugal force, so that the liquid is separated from the workpiece. The non-woven fabric 314 can adsorb some of the liquid, accelerate the separation of moisture on the surface of the parts, and through the spiral blades 316, the contact between the airflow and the surface of the workpiece can be increased during the rotation, removing excess moisture from the surface of the workpiece and improving the cleaning efficiency of the parts.

[0034] like Figure 1 , Figure 2 and Figure 5As shown, the control component 32 includes two mounting bases 321 fixedly connected to the upper end of the ultrasonic cleaner 1. A rotating column 322 is rotatably connected to the inner wall of the mounting base 321. A connecting frame 323 is fixedly connected to the lower end of the rotating column 322. A collar 324 is fixedly connected to the lower end of the connecting frame 323. The inner wall of the collar 324 is rotatably connected to the surface of the ring 312. An inner groove 325 is opened at the end of the rotating column 322 near the servo motor 33. A rotating shaft 326 is rotatably connected to the inner wall of the inner groove 325. One end of the rotating shaft 326 is fixedly connected to the output shaft of the servo motor 33. Pulleys 327 are fixedly connected to both the rotating shaft 326 and the surface of the uniform cleaning component 31. A transmission belt 328 is sleeved on the surface of the two pulleys 327.

[0035] In this embodiment, rotating the rotating column 322 can drive the outer metal mesh 311 to move under the cooperation of the connecting frame 323 and the collar 324, thereby controlling the depth of the outer metal mesh 311 inside the cleaning tank 2 and controlling the contact between the parts and the liquid. The rotating shaft 326 is driven to rotate by the servo motor 33, and the upper pulley 327 rotates with the rotating shaft 326. The lower pulley 327 drives the connecting plate 317 to rotate synchronously through the transmission belt 328. The connecting plate 317 drives the outer metal mesh 311 and the isolation frame 313 to rotate synchronously. The ring 312 and the collar 324 are both made of Teflon.

[0036] Working principle: The parts to be cleaned are placed between the non-woven fabric 314 and the inner net 315. The isolation frame 313 supports the non-woven fabric 314 and works with the inner net 315 to keep the non-woven fabric 314 in a ring shape. In the standby state, the cleaning tank 2 rapidly rotates the outer metal hard net 311 located in the cleaning liquid. The positioning bolt and the inner net 315 drive the spiral blade 316 to rotate as well, guiding impurities in the cleaning liquid in the outer metal hard net 311 to the outside. The non-woven fabric 314 forms an auxiliary filter for some impurities. The cleaning liquid passes through the surface of the outer metal hard net 311 and moves into the interior of the inner net 315. The spiral blade 316 discharges to the outside, and impurities on the surface of the workpiece are discharged to the outside synchronously with the liquid. When the liquid comes into contact with the surface of the part through the outer metal hard net 311, the non-woven fabric 314 provides auxiliary filtration. After cleaning, the rotating column 322 is rotated, and with the cooperation of the connecting frame 323 and the collar 324, the outer metal hard net 311 is moved to control the contact between the part and the liquid.

[0037] The outer metal mesh 311 is moved out of the liquid, driving the servo motor 33 to drive the rotating shaft 326 to rotate. The upper pulley 327 follows the rotating shaft 326, and the transmission belt 328 drives the lower pulley 327 to drive the connecting plate 317 to rotate synchronously. The connecting plate 317 drives the outer metal mesh 311 and the isolation frame 313 to rotate synchronously. The relatively fast rotation of the outer metal mesh 311 causes the liquid on the surface of the part to separate from the workpiece under the action of centrifugal force. The non-woven fabric 314 forms an adsorption effect on some of the liquid, accelerating the separation of moisture on the surface of the part. The spiral blades 316 increase the contact between the airflow and the surface of the workpiece during rotation, taking away excess moisture from the surface of the workpiece and improving the efficiency of part cleaning.

[0038] It should be noted that the ultrasonic cleaner 1 and servo motor 33 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the ultrasonic cleaner 1 and servo motor 33 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
