DETAILED DESCRIPTION

[0056] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0057] See also Figure 2 The present invention discloses an ultrasonic cleaning device for automobile thrust pad processing, which is used for cleaning thrust pads 100, and includes a frame 200, a cleaning box 300 installed on the frame 200, and a descaling mechanism 500 which is liftably arranged above the cleaning box 300;

[0058] See also Figure 3 , an ultrasonic generator 310 is installed outside the cleaning box 300, and multiple groups of cylindrical transducers 320 electrically connected to the ultrasonic generator 310 are installed inside the cleaning box 300;

[0059] See also Figure 4 The descaling mechanism 500 includes a mounting frame 510, on which a plurality of mounting grooves 511 for mounting the thrust washers 100 are arranged in an array; a pressing piece 520 for fixing the thrust washers 100 is arranged above each group of mounting grooves 511; a cleaning piece 530 for performing secondary treatment on the inner side of the thrust washers 100 and the oil groove 130 is rotatably arranged below each group of mounting grooves 511;

[0060] When the mounting frame 510 loaded with the thrust washer 100 moves downward into the cleaning box 300, the cleaning member 530 is flipped to a vertical state, the cylindrical transducer 320 is coaxially distributed with the corresponding thrust washer 100, and the cylindrical transducer 320 is used to pre-clean the peripheral thrust washer 100;

[0061] When the mounting frame 510 is lifted above the cleaning box 300 , the cleaning member 530 is turned over to a horizontal state to achieve secondary cleaning of the inner side of the thrust washer 100 and the oil groove 130 .

[0062] Specifically, the cleaning box 300 is filled with cleaning liquid, and the thrust pad 100 is sequentially embedded in the corresponding mounting groove 511 of the mounting frame 510, and then the thrust pad 100 is pressed and fixed on the mounting frame 510 by the pressing piece 520; the mounting frame 510 moves downward until the thrust pad 100 and the corresponding cylindrical transducer 320 are coaxially distributed, and at this time, the cleaning piece 530 is flipped to a vertical state and is located on one side of the mounting groove 511, so as to avoid interference with the cylindrical transducer 320; the cylindrical transducer 320 converts the high-frequency electrical signal generated by the ultrasonic generator 310 into mechanical vibration energy, thereby generating a radial vibration wave outward, and ultrasonically cleaning the thrust pad 100;

[0063] After the ultrasonic cleaning is completed, the mounting frame 510 moves upward, and the cleaning member 530 is flipped to a horizontal state. At this time, the cleaning member 530 is located directly below the thrust washer 100. The cleaning member 530 is used to perform secondary cleaning on the inner side of the thrust washer 100 and the oil groove 130 to remove residual oil stains.

[0064] It should be noted that, in the present invention, a cylindrical transducer 320 adapted to the contour of the thrust washer 100 is provided so that the vibration waves generated by it radiate radially outward. At the same time, the thrust washer 100 and the corresponding cylindrical transducer 320 are coaxially distributed, so that the amplitude of the radial vibration waves received by each area of ​​the thrust washer 100 remains consistent, thereby improving the consistency of the cleaning effect of each area of ​​the thrust washer 100.

[0065] For further information, see Figure 2 A lifting guide rail 210 is vertically mounted on the frame 200, a lifting frame 220 is slidably mounted on the lifting guide rail 210, the lower end of the lifting frame 220 is fixedly connected to the mounting frame 510, and a lifting cylinder 230 for driving the lifting frame 220 is also mounted on the frame 200;

[0066] By driving the lifting frame 220 to move up and down along the lifting guide rail 210 through the lifting cylinder 230, the mounting frame 510 can be driven to move up and down synchronously, thereby enabling the thrust washer 100 to enter and exit the cleaning box 300.

[0067] In one embodiment, see Figure 5 and Figure 6 The press member 520 includes a guide rod 521 vertically fixed to both sides of the mounting groove 511 and a press cover 522 slidably sleeved on the guide rod 521, and the press cover 522 is adapted to be engaged with the protrusion 110 of the thrust washer 100; a spring 523 is movably sleeved on the guide rod 521 and abuts against the press cover 522; a connecting frame 524 is fixed between adjacent press covers 522;

[0068] Specifically, each group of pressure covers 522 are synchronously lifted vertically along the guide rod 521 through the connecting frame 524, and then the oil groove 130 of the thrust washer 100 is inserted downward into the mounting groove 511, and the connecting frame 524 is loosened. Under the elastic force of the spring 523, the pressure cover 522 moves downward along the guide rod 521 until the two sides of the pressure cover 522 are engaged with the two side protrusions 110 of the thrust washer 100, thereby pressing and fixing the thrust washer 100 in the mounting groove 511, avoiding accidental detachment of the thrust washer 100, and improving the stability of the subsequent cleaning process.

[0069] For further information, see Figure 5 and Figure 6 The cleaning member 530 includes a first rotating shaft 531 rotatably mounted on one side of the mounting groove 511 and a swing rod 532 fixedly sleeved on the first rotating shaft 531, a second rotating shaft 533 is rotatably mounted on one end of the swing rod 532 away from the first rotating shaft 531, a U-shaped scraping member 536 is fixedly connected to the second rotating shaft 533 through a connecting rod 535, and the U-shaped scraping member 536 is adapted to the inner profile of the thrust washer 100; a first motor 534 for driving the second rotating shaft 533 is mounted on one side of the swing rod 532;

[0070] Specifically, when the mounting frame 510 enters the cleaning box 300 to perform ultrasonic cleaning of the thrust washer 100, the swing rod 532 is flipped to a vertical state through the first rotating shaft 531. At this time, the swing rod 532 and the U-shaped scraper 536 are located on one side of the cylindrical transducer 320, so that the mounting frame 510 will not interfere with the cylindrical transducer 320 during the lifting process, so that the thrust washer 100 can smoothly reach a position coaxially distributed with the cylindrical transducer 320, thereby ensuring the consistency of the thrust washer 100 during ultrasonic cleaning;

[0071] When the ultrasonic cleaning is completed, the mounting frame 510 is taken out of the cleaning box 300, and the swing rod 532 is flipped to a horizontal state through the first rotating shaft 531. At this time, the swing rod 532 and the U-shaped scraper 536 are located directly below the thrust washer 100, and the second rotating shaft 533 coincides with the axis of the thrust washer 100; the second rotating shaft 533 is driven to rotate by the first motor 534, thereby driving the U-shaped scraper 536 to move in a circle around the second rotating shaft 533, and the U-shaped scraper 536 is used to clean the inner side of the thrust washer 100 and the oil groove 130.

[0072] See also Figure 7 The U-shaped scraper 536 includes a shell 5361, an accommodating cavity 5362 is provided inside the shell 5361, a scraper bladder 5363 matching the inner contour of the thrust washer 100 is provided in the accommodating cavity 5362, and an expansion portion 5364 matching the oil groove 130 is provided in the middle of the scraper bladder 5363;

[0073] When the U-shaped scraper 536 moves in a circular motion, the scraper sac 5363 contacts the inner wall of the thrust washer 100, so that the scraper sac 5363 can scrape off the residual oil stains on the inner wall of the thrust washer 100; in addition, when the scraper sac 5363 contacts the inner wall of the thrust washer 100, the scraper sac 5363 is reversely squeezed by the thrust washer 100, so that the expansion portion 5364 expands outward, and then the expansion portion 5364 fits tightly with the oil groove 130, and the expansion portion 5364 is used to scrape out the oil stains in the oil groove 130, thereby improving the cleaning effect.

[0074] See also Figure 8 In order to further improve the cleaning effect of the U-shaped groove 120 of the thrust washer 100, a drainage tube 525 is arranged in the middle of the pressure cover 522, and a third rotating shaft 526 is vertically rotatably installed in the drainage tube 525. The third rotating shaft 526 is provided with a spiral blade 527 adapted to the drainage tube 525, and a splitter blade 528 is arranged at the lower end of the third rotating shaft 526. The splitter blade 528 is located in the U-shaped groove 120 of the thrust washer 100; a sprocket 529 is installed at the upper end of the third rotating shaft 526, and a second motor 5210 for driving the sprocket 529 is installed on the connecting frame 524, and adjacent sprockets 529 are connected by a transmission chain 5211;

[0075] Specifically, see Fig. 9 During the ultrasonic cleaning process, under the transmission action of the transmission chain 5211, the second motor 5210 drives each sprocket 529 to rotate synchronously, thereby driving the corresponding third rotating shaft 526 to rotate, and then driving the spiral blade 527 on the third rotating shaft 526 to rotate, so as to guide the cleaning liquid above the pressing cover 522 downward into the U-shaped groove 120 through the drainage tube 525. At the same time, the third rotating shaft 526 drives the diverter blade 528 to rotate synchronously, so that the cleaning liquid guided into the U-shaped groove 120 is diverted to both sides of the U-shaped groove 120 and flows out from the openings on both sides below the U-shaped groove 120 (i.e. Fig. 9 The spiral blade 527 and the diverter blade 528 are used to make the cleaning liquid in the U-shaped groove 120 flow continuously, so that the cleaning liquid mixed with oil and dirt in the U-shaped groove 120 is continuously discharged downward, and at the same time, the clean cleaning liquid above is continuously replenished into the U-shaped groove 120, so as to avoid the cleaning effect being affected by the excessive oil and dirt content in the cleaning liquid in the U-shaped groove 120.

[0076] It should be noted that in order to prevent the cleaning liquid from penetrating into the first motor 534 and the second motor 5210 and causing damage thereto, a waterproof cover is provided on the outside of the first motor 534 and the second motor 5210 .

[0077] See also Fig.10 , Fig.11 and Fig.12, for adjusting the posture of the swing rod 532, a gear 537 is installed at one end of the first rotating shaft 531, and a rack 340 meshing with the gear 537 is vertically installed in the cleaning box 300, and the rack 340 is located above the cylindrical transducer 320;

[0078] When the mounting frame 510 moves downward and passes the rack 340, the gear 537 meshes with the rack 340, driving the first rotating shaft 531 to rotate forward, so as to flip the swing rod 532 to a vertical state;

[0079] When the mounting frame 510 moves upward and passes the rack 340, the gear 537 meshes with the rack 340, driving the first rotating shaft 531 to reverse, so as to flip the swing rod 532 to a horizontal state;

[0080] Specifically, see Fig.10 , when the mounting bracket 510 is lowered into position, the swing rod 532 is in a vertical state, so as not to interfere with the cylindrical transducer 320;

[0081] See also Fig.11 and Fig.12 During the upward movement of the mounting frame 510, when the gear 537 begins to mesh with the lower end of the rack 340, the swing rod 532 flips synchronously until the gear 537 reaches the upper end of the rack 340, and the swing rod 532 just flips to a horizontal state, and then the gear 537 is disengaged from the rack 340, and the swing rod 532 remains in a horizontal state until the mounting frame 510 rises to its position, preparing for the subsequent secondary cleaning;

[0082] During the downward movement of the mounting frame 510, when the gear 537 begins to mesh with the upper end of the rack 340, the rocker arm 532 flips synchronously until the gear 537 reaches the lower end of the rack 340, at which time the rocker arm 532 just flips to a vertical state, and then the gear 537 disengages from the rack 340, and the rocker arm 532 remains in a vertical state.

[0083] It should be noted that the first rotating shaft 531 rotates only when the gear 537 is meshed with the rack 340 . When the gear 537 is disengaged from the rack 340 , the first rotating shaft 531 can maintain the current state unchanged.

[0084] In yet another embodiment, see Fig.13 , further comprising a treatment box 400 installed in the frame 200, wherein the inlet of the treatment box 400 and the outlet of the cleaning box 300 are connected with a liquid outlet pipe 410, and a first infusion pump 330 is installed at the outlet of the cleaning box 300; the outlet of the treatment box 400 and the inlet of the cleaning box 300 are connected with a liquid inlet pipe 420, and a second infusion pump 430 is installed on the liquid inlet pipe 420;

[0085] When the cleaning liquid in the cleaning box 300 needs to be purified, the first infusion pump 330 is turned on to pump the cleaning liquid in the cleaning box 300 into the treatment box 400 through the outlet pipe 410 for purification; then the purified cleaning liquid is pumped into the cleaning box 300 again through the inlet pipe 420 by the second infusion pump 430, thereby achieving purification and recycling of the cleaning liquid.

[0086] For further information, see Fig.14 , a partition 401 is provided in the processing box 400, and the partition 401 separates the processing box 400 into a sedimentation area 402 and a purification area 403, and the sedimentation area 402 is located at the inlet side of the processing box 400, and a splash-proof guide cover 404 extending into the bottom of the sedimentation area 402 is provided at the inlet of the processing box 400, and the lower end of the splash-proof guide cover 404 is provided with an opening;

[0087] Specifically, the first infusion pump 330 pumps the cleaning liquid in the cleaning box 300 into the processing box 400 through the liquid outlet pipe 410. The cleaning liquid reaches the bottom of the sedimentation area 402 under the diversion effect of the splash-proof deflector 404. After the cleaning liquid in the sedimentation area 402 is allowed to stand, the oil and dirt in the cleaning liquid sink to the bottom of the sedimentation area 402. When the cleaning liquid level exceeds the upper end of the partition 401, the upper cleaning liquid after standing can flow into the purification area 403, thereby realizing the sedimentation and separation of the oil and dirt.

[0088] It should be noted that the splash-proof deflector 404 can not only guide the cleaning liquid so that the cleaning liquid entering the treatment box 400 is always at the bottom of the sedimentation area 402, so that the cleaning liquid from which the oil and dirt are separated in the upper layer continuously enters the purification area 403; at the same time, the splash-proof deflector 404 can prevent the cleaning liquid entering later from impacting the cleaning liquid entering earlier and causing the precipitated oil and dirt to float up again, thereby ensuring the oil and dirt separation effect.

[0089] See also Fig.15 A first filter element 440 is disposed on the liquid inlet pipe 420 between the processing box 400 and the second infusion pump 430. The first filter element 440 includes a shell 441. A filter plate 442 is installed in the shell 441. The filter plate 442 is provided with a plurality of filter holes 443.

[0090] See also Fig.16 A second filter element 450 is provided on the liquid inlet pipe 420 between the second infusion pump 430 and the cleaning box 300. The second filter element 450 includes a cylindrical shell 451. A filter element 452 is detachably installed in the cylindrical shell 451. An end cover 453 is installed on the upper end of the cylindrical shell 451. A pressing sheet 454 is provided between the end cover 453 and the filter element 452.

[0091] The cleaning liquid that has been precipitated and purified in the processing box 400 flows into the outer shell 441, and the filter plate 442 can intercept large particles of low-density debris that have not been cleaned in the processing box 400; then when the cleaning liquid flows through the second filter element 450, the filter element 452 can further intercept small particles of impurities in the cleaning liquid, thereby effectively improving the purification effect of the cleaning liquid.
