[0001] The present invention relates to the technical field of cleaning spray-painted automotive parts, and particularly relates to a cleaning device for spray-painted automotive parts. Background Art

[0002] Automotive parts are each unit that constitutes an entire vehicle and a product serving the vehicle. After spray-painting the automotive parts, spray-painted automotive parts are produced. After processing the spray-painted automotive parts, it is necessary to clean their surfaces to avoid dust on the surfaces of the spray-painted automotive parts, which may affect the subsequent packaging of the spray-painted automotive parts.

[0003] During the process of cleaning spray-painted automotive parts, the general cleaning method is blowing cleaning. By blowing, not only will the surface of the spray-painted automotive parts not be damaged, but also resources such as cleaning agents and water can be saved. However, when blowing and cleaning the spray-painted automotive parts, it is necessary to first fix the spray-painted automotive parts. After fixing, it is also necessary to start the blowing cleaning equipment to clean them. This method of first fixing and then operating the equipment by the operator to clean will increase the workload during the cleaning process of the spray-painted automotive parts and also reduce the cleaning efficiency of the spray-painted automotive parts.

[0022] 4. The present invention utilizes the setting of the arc head block to ensure that when the second connecting tooth member and the first connecting tooth member are in contact and transmission, the rotation effect of the second connecting tooth member is not affected, thereby ensuring that the second connecting tooth member drives the sleeve to rotate normally.

[0023] 5.

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] As Figures 1-8 shown, a cleaning device for spraying automobile parts includes a cleaning box 1. A pushing electric telescopic rod 2 is installed on the lower side of the inner wall of the cleaning box 1. The output end shaft wall of the pushing electric telescopic rod 2 is provided with a plurality of arc-shaped clamping plates 3, and the plurality of arc-shaped clamping plates 3 are rotationally connected to the output shaft of the pushing electric telescopic rod 2 through two fixed plates 4;

[0035] A limiting cone cylinder 5 is fixedly installed below the lower side of the inner wall of the cleaning box 1 and below a number of arc-shaped clamping plates 3. The output end of the push electric telescopic rod 2 is located within the limiting cone cylinder 5. The limiting cone cylinder 5 can ensure that when the arc-shaped clamping plates 3 fall and expand to the maximum fixed angle, they will not expand even if they continue to move on the inner wall. It can ensure that when the push electric telescopic rod 2 moves downward to drive the structure to engage the two connecting tooth parts, the sprayed automotive parts will also be stably fixed, ensuring the normal use function of the arc-shaped clamping plates 3. A pushing mechanism for pushing a number of arc-shaped clamping plates 3 is provided. On the lower side of the interior of the cleaning box 1, a transmission cavity 6 and a cleaning groove 7 on the transmission cavity 6 are symmetrically opened. On the opposite side of the inner walls of the two transmission cavities 6, a long shaft motor 8 is fixedly installed, and the output shaft of the long shaft motor 8 is erected inside the transmission cavity 6 through a support hole plate 9. The output shafts of the two long shaft motors 8 are both provided with an output mechanism for the power output of the pushing mechanism. The pushing mechanism includes a pushing ring 10 fixedly installed at the output end of the push electric telescopic rod 2. The pushing ring 10 is fixedly installed above a pushing inclined block 12 through a vertical block 11. A first tension spring 13 is fixedly installed on the opposite sides of a number of arc-shaped clamping plates 3.

[0036] The output mechanism includes a first connecting tooth part 14 fixedly installed on the output shaft of the long-axis motor 8. A second connecting tooth part 15 is fixedly installed on the output shaft of the long-axis motor 8 through a sleeved sleeve 37. A retaining ring 16 is fixedly installed on one side of the sleeve wall of the sleeve 37 close to the second connecting tooth part 15. A plurality of cross bars 40 are sleeved between the retaining ring 16 and the support hole plate 9 to install a second tension spring 17. One ends of the plurality of cross bars 40 close to the retaining ring 16 are fixedly installed together with a rotating connecting ring 38. The rotating connecting ring 38 can, without affecting the normal rotation of the sleeve 37 and the retaining ring 16, pull the second connecting tooth part 15 through the provided second tension spring 17, so as to push the push electric telescopic rod 2 upward. When the push inclined block 12 moves away from the sliding wheel 22, the first connecting tooth part 14 and the second connecting tooth part 15 are separated, which will not affect the rotation of the rotating cross plate 25 under the action of the return spring 39, and avoid the problem that the sprayed automotive parts cannot be pushed out. Two arc head blocks 18 are symmetrically arranged between the retaining ring 16 and the second connecting tooth part 15. Connecting vertical rods 20 are fixedly installed on the surfaces of the two arc head blocks 18 through mounting arc plates 19. The upper ends of the connecting vertical rods 20 are rotatably installed with sliding wheels 22 through fixed groove blocks 21, and the surfaces of the sliding wheels 22 are in contact with the push inclined block 12. The rod wall of the connecting vertical rod 20 is rotatably connected to the inner wall of the transmission cavity 6 through a first longitudinal axis 23. A rotating cross plate 25 is rotatably connected to the inner wall of the cleaning groove 7 through a second longitudinal axis 24. Return springs 39 are installed on opposite sides of the shaft wall of the second longitudinal axis 24, and one end heads of the return springs 39 are fixedly installed on the inner wall of the cleaning groove 7. The return springs 39 can generate a turning force. In this way, after the long-axis motor 8 releases the rotational output force on the sleeve 37, the rotating cross plate 25 can turn back and retract into the cleaning groove 7, which can avoid affecting the pushing out of the sprayed automotive parts. A jacking mechanism for jacking the rotating cross plate 25 is provided on the side of the sleeve wall of the sleeve 37 away from the second connecting tooth part 15. The jacking mechanism includes a jacking gear 26 fixedly installed on the sleeve wall of the sleeve 37. A jacking vertical plate 28 is installed on the surface of the jacking gear 26 through a toothed plate 27. The top surface of the jacking vertical plate 28 penetrates through the transmission cavity 6 and the top surface of the jacking vertical plate 28 is rotatably connected to the rotating cross plate 25 through a fixed hole block 29. A cleaning mechanism is provided on the top of the rotating cross plate 25;

[0037] The cleaning mechanism includes a connecting cross pipe 30 fixedly installed on the top of the rotating cross plate 25. One end of the connecting cross pipe 30 is fixedly installed with a plurality of nozzles 32 through a T-shaped pipe 31, and the other end of the connecting cross pipe 30 is fixedly installed with an air pipe 33. A top groove plate 34 is fixedly installed on the upper side of the inner wall of the cleaning groove 7 above the air pipe 33. An extrusion block 36 is fixedly installed on the surface of the jacking vertical plate 28 on the lower side of the rotating cross plate 25 through an L-shaped block 35.

[0038] Such as Figures 1-6As shown, in some embodiments, the inclined surface of the limit cone 5 is slidably connected to the lower ends of several arc-shaped clamping plates 3. By using the conical tube structure of the limit cone 5, it can ensure that the arc-shaped clamping plates 3 expand during the movement on the inclined surface of the limit cone 5, and then can clamp the sprayed automotive parts, ensuring the fixing stability of the sprayed automotive parts and facilitating the subsequent air blowing and cleaning. The output ends of the two long-axis motors 8 are respectively rotatably connected to the inner wall of the corresponding transmission cavity 6. The opposite ends of several first tension springs 13 are fixedly installed on the output end arm of the push electric telescopic rod 2. The opposite ends of several second tension springs 17 are respectively fixedly installed with the support hole plate 9 and the rotating connection ring 38. The surface of the rotating connection ring 38 is embedded into the surface of the retaining ring 16. Several arc-shaped clamping plates 3 are equidistantly arranged on the periphery of the output shaft of the push electric telescopic rod 2, and several arc-shaped clamping plates 3 are all of a horizontal N-shaped structure. The upper opening ends of several arc-shaped clamping plates 3 are set to be more than twice as long as the lower opening ends. By setting the different openings of the arc-shaped structure of the arc-shaped clamping plates 3, the arc-shaped clamping plates 3 can move a small distance along the inclined surface of the limit cone 5, ensuring a large distance expansion at the upper side position of the arc-shaped clamping plates 3, ensuring the expansion and fixation of the sprayed automotive parts, and ensuring the processing stability of the device. The first connecting tooth part 14 and the second connecting tooth part 15 are both circular groove blocks with inclined arc grooves opened on one side surface. The first connecting tooth part 14 and the second connecting tooth part 15 are opposite to each other and the directions of the internal grooves are opposite. By using the opposite groove settings of the first connecting tooth part 14 and the second connecting tooth part 15, it can ensure the transmission effect of the rotational force after the two connecting tooth parts are in contact.

[0039] The two arc head blocks 18 are rod structures with circular arc heads, which can reduce the friction with the sleeve 37. By using the setting of the arc head blocks 18, it can ensure that when the second connecting tooth part 15 and the first connecting tooth part 14 are in contact and transmit power, it does not affect the rotation effect of the second connecting tooth part 15, ensuring the normal rotation of the second connecting tooth part 15 driving the sleeve 37. The two top vertical plates 28 are both rectangular rod structures. The positions of the two T-shaped tubes 31 are outside the cleaning groove 7, and multiple nozzles 32 are equidistantly arranged on the pipe wall of the T-shaped tubes 31. The two top groove plates 34 are both plate structures and are provided with circular grooves on the bottom surface that match the air pipes 33. By setting the T-shaped tubes 31 outside the cleaning groove 7, it can ensure the moving space of the T-shaped tubes 31, and the moving T-shaped tubes 31 can also better clean the surface of the sprayed automotive parts, ensuring the cleaning quality of the sprayed automotive parts. The two L-shaped blocks 35 are structures composed of L-shaped plates and triangular blocks installed inside the L-shaped plates. The two extrusion blocks 36 are both circular column structures. By setting the extrusion blocks 36, it can ensure that when the T-shaped tubes 31 are lowered, the gas is led out through the air pipes 33.

[0040] Working principle of the present invention: Before the device is used, the air pipe 33 is connected to the air pump to ensure the normal delivery of gas, and the electric telescopic rod 2 is pushed to push several arc-shaped clamping plates 3 out of the cleaning box 1. At this time, under the pulling force of the first tension spring 13, the arc-shaped clamping plates 3 will move closer to the electric telescopic rod 2. Then, the sprayed automotive parts are placed on several arc-shaped clamping plates 3, and then the cleaning of the sprayed automotive parts is carried out;

[0041] The electric telescopic rod 2 is pushed to move several arc-shaped clamping plates 3 downward. During the movement, the arc-shaped clamping plates 3 will contact the limiting cone 5 and slide on the inclined surface of the limiting cone 5. Since the inclined surface of the limiting cone 5 is inclined inward, the upper ends of the arc-shaped clamping plates 3 will open outwards, thereby expanding and fixing the sprayed automotive parts. As the electric telescopic rod 2 continues to move downward, through the pushing inclined block 12 connected to the vertical block 11 on the pushing ring 10, the sliding wheel 22 can be squeezed to tilt. The sliding wheel 22 drives the connecting vertical rod 20 to rotate around the first longitudinal axis 23 through the fixed groove block 21. At this time, the connecting vertical rod 20 will drive the arc head block 18 to move through the mounting arc plate 19, so that the first connecting tooth part 14 and the second connecting tooth part 15 are in contact and drive;

[0042] After the first connecting tooth part 14 and the second connecting tooth part 15 are engaged, the rotational output force of the long-axis motor 8 will be transmitted to the jacking gear 26 through the sleeve 37, causing the jacking gear 26 to drive the toothed plate 27 to move. The movement of the toothed plate 27 will drive the rotating cross plate 25 to rotate through the jacking vertical plate 28. Since the jacking vertical plate 28 moves downward, it will drive the extrusion block 36 on the L-shaped block 35 away from the top groove plate 34. In this way, the gas of the air pump will be introduced into the connecting cross pipe 30 through the air pipe 33 and sprayed out through the T-shaped pipe 31 and the nozzle 32 connected to the connecting cross pipe 30. The fixed sprayed automotive parts can be cleaned through multiple nozzles 32;

[0043] After cleaning, the electric telescopic rod 2 is pushed upward. Under the pulling force of the first tension spring 13, the arc-shaped clamping plates 3 contract relatively, which can release the limit on the sprayed automotive parts. And under the pulling force of the second tension spring 17, the first connecting tooth part 14 and the second connecting tooth part 15 are separated. And under the turning force of the corresponding return spring 39, the jacking vertical plate 28 can be moved upward, so that the T-shaped pipe 31 is retracted into the cleaning tank 7, and the L-shaped block 35 squeezes the air pipe 33 through the extrusion block 36 in cooperation with the top groove plate 34 to prevent the nozzle 32 from jetting air. When the electric telescopic rod 2 pushes out the sprayed automotive parts, the operator takes the cleaned sprayed automotive parts, and then puts the sprayed automotive parts to be cleaned again to ensure the reprocessing of the sprayed automotive parts.

[0044] The prominent innovative structure of the present invention will not elaborate too much on the existing mature technologies and structures.

[0045] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
