Description

Technical Field

[0001] The present invention relates to the technical field of bearing seat surface cleaning, and specifically relates to a surface cleaning device for bearing seat spraying. Background Art

[0002] The bearing seat is an important component in mechanical equipment for supporting and fixing bearings. Its main function is to provide a stable installation position for the bearings, ensure the normal operation of the bearings, and thus guarantee the smooth operation of the entire mechanical system. In order to reduce the noise during the operation of the bearings and dissipate heat from the operating bearing seats, two circular grooves are provided on the surface of some bearing seats.

[0003] After the bearing seat is processed, its surface usually needs to be sprayed. Since there will be some iron filings on the surface of the processed bearing seat, the presence of the iron filings will damage the cleanliness of the substrate surface, resulting in a decrease in the adhesion between the paint film and the substrate, thus affecting the subsequent spraying of the bearing seat. Therefore, it is necessary to clean the surface of the bearing seat before spraying.

[0004] The existing cleaning of the bearing seat is to spray high-pressure water on the surface of the bearing seat through spraying, and spray the iron filings on the surface of the bearing seat away. However, during the cleaning process, the inside of the circular grooves on the surface of the bearing seat cannot be effectively cleaned. The spraying water cannot accurately enter the inside of the circular grooves of the bearing seat to spray out most of the iron filings inside the circular grooves, resulting in some iron filings remaining inside the circular grooves. Furthermore, after the bearing seat surface is sprayed, the remaining iron filings will form particles or protrusions in the coating, causing the coating thickness to be uneven and reducing the heat dissipation effect of the bearing seat.

[0005] Therefore, it is very necessary to design a surface cleaning device for bearing seat spraying that can automatically clean the inside of the circular grooves of the bearing seat and has high cleaning efficiency. Summary of the Invention

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1. Please refer to Figures 1-10 , the present invention provides a technical solution: a surface cleaning device for bearing housing spraying, including a support box 1 and a bearing housing 58. Circular grooves 581 are provided on both side surfaces of the bearing housing 58. A support frame 2 is fixedly connected to one side of the support box 1. A water circulation mechanism 3 for filtering and reusing the sprayed water is provided on the upper side of the support box 1. A spraying mechanism 4 for spraying water on the surface of the bearing housing 58 from different angles under high pressure is provided on the upper side of the support frame 2. A transmission mechanism 5 for clamping and transporting the bearing housing 58 is provided under the spraying mechanism 4. Groove cleaning mechanisms 6 for flushing the circular grooves 581 on the surface of the bearing housing 58 are provided on both sides of the transmission mechanism 5.

[0042] Please refer to Figure 2 , the water circulation mechanism 3 includes a first water storage bucket 31 fixedly connected to the upper side of the support box 1. A first hard pipe 32 is fixedly connected to the water inlet end of the first water storage bucket 31. The other end of the first hard pipe 32 is fixedly connected to a filter pipe 33. A second hard pipe 35 is fixedly connected to the input end of the filter pipe 33. A second water pump 36 is provided at the other end of the second hard pipe 35. The second water pump 36 is fixedly connected to the support box 1 and its output end is fixedly connected to the second hard pipe 35. A third hard pipe 37 is fixedly connected to the input end of the second water pump 36. A water tank 38 is provided inside the support box 1. The other end of the third hard pipe 37 penetrates the side wall of the water tank 38 and is fixedly connected to the water tank 38.

[0043] Specifically, the inside of the water tank 38 is used to store the rinsed water source. The second water pump 36 is used to extract the water source inside the water tank 38, filter it through the filter pipe 33, filter out the impurities in the water, and finally extract it into the first water storage bucket 31.

[0044] A fourth hard pipe 39 is fixedly connected to the water outlet end of the first water storage bucket 31. A first water pump 34 is provided at the other end of the fourth hard pipe 39. The first water pump 34 is fixedly connected to the support box 1 and its input end is fixedly connected to the fourth hard pipe 39. The output end of the first water pump 34 is fixedly connected to a water outlet pipe.

[0045] Specifically, the first water pump 34 is used to extract the water source inside the first water storage bucket 31 into the spraying mechanism 4 for use.

[0046] Please refer to Figure 3, the spraying mechanism 4 includes a water collecting pipe 41 fixedly connected to the upper side of the support frame 2. The other end of the water outlet pipe is fixedly connected to the water collecting pipe 41. A plurality of spray pipes 42 are uniformly and fixedly connected to the lower side of the water collecting pipe 41. Four spray nozzles 43 are fixedly connected to the lower side of each spray pipe 42. The spraying directions of two of the spray nozzles 43 are respectively towards both sides of the bearing seat 58, and the spraying directions of the other two spray nozzles 43 are both towards the upper side of the bearing seat 58.

[0047] Specifically, the water collecting pipe 41 is used to collect all the extracted water sources and disperse all the water sources into each spray pipe 42. The spray pipe 42 then transmits the water source into the four spray nozzles 43. Two of the spray nozzles 43 are set at an oblique angle to spray the water sources onto both sides of the bearing seat 58 respectively, and the spraying directions of the other two spray nozzles 43 are directly downward, so as to spray the upper side of the bearing seat 58.

[0048] Please refer to Figure 4 , the transmission mechanism 5 includes a bracket 51 arranged inside the support frame 2. Two side plates 52 are fixedly connected to the upper side of the bracket 51. Two first motors 56 are fixedly connected to one side of one of the side plates 52. The output end of each first motor 56 penetrates the side plate 52 and is fixedly connected to a rotating shaft 54. A roller 53 is fixedly connected to the outer side of each rotating shaft 54. A rubber belt 55 is slidably connected to the outer side of each roller 53. A plurality of clamping jaws 57 are uniformly fixedly connected to the outer side of the rubber belt 55. Each bearing seat 58 is clamped at the clamping ends of two clamping jaws 57.

[0049] Specifically, the clamping jaw 57 is used to clamp and fix the bearing seat 58. The rotation of the output end of the first motor 56 is used to control the rotation of the roller 53. When the roller 53 rotates, it drives the rubber belt 55 to move, thereby driving the clamping jaw 57 to move, and thus driving each bearing seat 58 to be cleaned in turn.

[0050] By setting the transmission mechanism 5 to control the movement of the bearing seat 58, the spray nozzles 43 with different spraying angles spray the water source at high pressure on the surface of the bearing seat 58, thereby automatically driving each bearing seat 58 to be cleaned in turn. Moreover, the spraying ranges of the spray nozzles 43 with different angles are wide, and most of the iron filings on the surface of the bearing seat 58 can be effectively washed away, achieving the effect of automatically cleaning the iron filings on the surface of the bearing seat 58.

[0051] Embodiment 2. In the existing cleaning of the bearing seat 58, high-pressure sprayed water is used to spray the surface of the bearing seat 58 to spray off the iron filings on the surface of the bearing seat 58. However, during the cleaning process, the inside of the circular groove 581 on the surface of the bearing seat 58 cannot be effectively cleaned. The sprayed water cannot accurately enter the inside of the circular groove 581 of the bearing seat 58 to spray out most of the iron filings inside the circular groove 581, resulting in some iron filings remaining inside the circular groove 581. Furthermore, after spraying on the circular groove 581 on the surface of the bearing seat 58, the remaining iron filings will form particles or protrusions in the coating, causing the coating thickness to be uneven and reducing the heat dissipation effect of the bearing seat 58. Therefore, the following structure is designed to solve the above technical problems.

[0052] Please refer to Figure 6 , the groove cleaning mechanism 6 includes a first cylinder 61 fixedly connected inside the support frame 2. The output end of the first cylinder 61 is fixedly connected with a U-shaped plate 62. The inner side wall of the U-shaped plate 62 is rotatably connected with a second bevel gear 65. The outside of the U-shaped plate 62 is fixedly connected with a second motor 67. The output end of the second motor 67 penetrates the U-shaped plate 62 and is fixedly connected with a third bevel gear 66. The inner upper wall of the U-shaped plate 62 is rotatably connected with a first bevel gear 63. Both the second bevel gear 65 and the third bevel gear 66 are meshed with the first bevel gear 63, and the second bevel gear 65 and the third bevel gear 66 are on the same axis.

[0053] Specifically, the telescoping of the output end of the first cylinder 61 is used to control the movement of the U-shaped plate 62, thereby driving the first spraying component 68 and the second spraying component 69 to approach or move away from the circular groove 581 on the surface of the bearing seat 58. The rotation of the output end of the second motor 67 is used to control the rotation of the third bevel gear 66, thereby controlling the rotation of the first bevel gear 63, and indirectly controlling the rotation of the second bevel gear 65.

[0054] When the output end of the second motor 67 rotates counterclockwise, it drives the third bevel gear 66 to rotate counterclockwise, thereby driving the first bevel gear 63 to rotate clockwise, and indirectly driving the second bevel gear 65 to rotate clockwise. When the output end of the second motor 67 rotates clockwise, it drives the third bevel gear 66 to rotate clockwise, thereby driving the first bevel gear 63 to rotate counterclockwise, and indirectly driving the second bevel gear 65 to rotate counterclockwise.

[0055] The inside of the U-shaped plate 62 is respectively provided with a first avoidance groove and a second avoidance groove. A first connecting rod is arranged inside the first avoidance groove, and a second connecting rod is arranged inside the second avoidance groove. One end of the first connecting rod is fixedly connected to the center of the second bevel gear 65 and the other end is provided with a first spraying component 68. One end of the second connecting rod is fixedly connected to the center of the third bevel gear 66 and the other end is provided with a second spraying component 69.

[0056] Specifically, while the third bevel gear 66 rotates, it drives the second injection assembly 69 to rotate synchronously around the center of the third bevel gear 66. While the second bevel gear 65 rotates, it drives the first injection assembly 68 to rotate synchronously around the center of the second bevel gear 65.

[0057] A second water storage bucket and a third water pump 64 are fixedly connected to the upper side of the U-shaped plate 62. The input end of the third water pump 64 is connected to the second water storage bucket through a pipeline, and the output end of the third water pump 64 is fixedly connected to a second water outlet pipe and a third water outlet pipe respectively.

[0058] Specifically, the third water pump 64 is used to extract the water source inside the second water storage bucket and deliver it into the first injection pipe 683 and the second injection pipe 691 respectively, and then spray it out from the output ends of the first injection pipe 683 and the second injection pipe 691.

[0059] Please refer to Figures 7-8 , the first injection assembly 68 includes a first injection pipe 683 fixedly connected to the other end of the first connecting rod. The first injection pipe 683 is fixedly connected to the second water outlet pipe. The second injection assembly 69 includes a second injection pipe 691 fixedly connected to the other end of the second connecting rod. The second injection pipe 691 is fixedly connected to the third water outlet pipe. The diameters of the first injection pipe 683 and the second injection pipe 691 are the same as the width of the circular groove 581 of the bearing seat 58.

[0060] Specifically, please refer to Figure 6 , in the initial state, the spraying directions of the first injection pipe 683 and the second injection pipe 691 are aligned above the inside of the circular groove 581 of the bearing seat 58. The first injection pipe 683 deviates counterclockwise by five degrees, and the second injection pipe 691 deviates clockwise by five degrees. When the transmission mechanism 5 controls the bearing seat 58 to move to the middle of the two groove cleaning mechanisms 6, the output end of the first cylinder 61 extends to control the first injection pipe 683 and the second injection pipe 691 to extend into the circular groove 581 of the bearing seat 58. At this time, the third water pump 64 extracts the water source inside the second water storage bucket and delivers it into the first injection pipe 683 and the second injection pipe 691 respectively, and then sprays it out from the output ends of the first injection pipe 683 and the second injection pipe 691, spraying inside the circular groove 581 of the bearing seat 58.

[0061] While the first injection pipe 683 and the second injection pipe 691 are injecting water source, the output end of the second motor 67 rotates clockwise, driving the third bevel gear 66 to rotate clockwise, thereby driving the first bevel gear 63 to rotate counterclockwise, and then indirectly driving the second bevel gear 65 to rotate counterclockwise. At this time, the first injection pipe 683 rotates counterclockwise along the center of the second bevel gear 65, and the second injection pipe 691 rotates clockwise along the center of the third bevel gear 66 until the output end of the second motor 67 rotates clockwise by 170 degrees. At this time, the injection directions of the first injection pipe 683 and the second injection pipe 691 are aligned with the lower part inside the circular groove 581 of the bearing seat 58, indicating that the cleaning of one circle of the circular groove 581 of the bearing seat 58 has been completed. The third water pump 64 stops pumping water source, and the output end of the first cylinder 61 retracts to drive the first injection pipe 683 and the second injection pipe 691 to move back to their positions. The output end of the second motor 67 rotates counterclockwise by 170 degrees to drive the first injection pipe 683 and the second injection pipe 691 to rotate back to their positions.

[0062] By setting the groove cleaning mechanism 6, after the surface of the bearing seat 58 is cleaned by the nozzle 43, the first cylinder 61 controls the first injection pipe 683 and the second injection pipe 691 to extend into the inside of the circular groove 581 of the bearing seat 58, and the second motor 67 controls the first injection pipe 683 and the second injection pipe 691 to rotate in different directions respectively, so as to spray and clean one circle of the circular groove 581 of the bearing seat 58, wash away the iron filings inside, effectively preventing the iron filings from remaining inside the circular groove 581 of the bearing seat 58 and affecting the subsequent spraying, achieving the effect of automatically cleaning the inside of the circular groove 581 of the bearing seat 58.

[0063] Embodiment 3. Since the circular grooves 581 of some bearing seats 58 are too deep, when the spray water is sprayed inward, the impact force of the high-pressure water will cause the iron filings to move along the track of the circular groove 581. When the spray water is sprayed above the inside of the circular groove 581 of the bearing seat 58, some iron filings will be washed away from the inside of the groove, and some iron filings will be washed to the lower part inside the circular groove 581. When the spray water is sprayed below the inside of the circular groove 581 of the bearing seat 58, some iron filings will be washed away from the inside of the groove, and some iron filings will be washed to the upper part inside the circular groove 581, resulting in a longer cleaning time for the iron filings in the circular groove 581, a reduced cleaning efficiency, and an inability to quickly wash away the iron filings from the inside of the circular groove 581. Therefore, the following structure is designed to solve the above technical problems.

[0064] Please refer to Figure 7, inside the first injection pipe 683, there is a first water passage groove 681. Outside the first water passage groove 681, there is a first sliding groove 684. Inside the first sliding groove 684, there is a first spring 682. One end of the first spring 682 is fixedly connected to the first injection pipe 683 and the other end is fixedly connected to a first sliding pipe 686. The first sliding pipe 686 is slidably connected to the first sliding groove 684. Inside the first sliding pipe 686, a number of first drainage holes 685 are evenly arranged. Outside the first injection pipe 683, a rubber plug 687 is fixedly connected.

[0065] Specifically, when water source enters the inside of the first injection pipe 683, it flows into the inside of the first sliding pipe 686 through the first water passage groove 681. The water source inside the first sliding pipe 686 is then ejected from each first drainage hole 685 in sequence. When one end of the first sliding pipe 686 is squeezed, the first sliding pipe 686 slides into the inside of the first sliding groove 684. At this time, the first spring 682 is compressed. When the first spring 682 is completely compressed, the first sliding pipe 686 completely slides into the inside of the first sliding groove 684. At this time, the first drainage holes 685 are blocked by the first sliding groove 684 and water cannot flow out. When one end of the first sliding pipe 686 is no longer squeezed, the first sliding pipe 686 is pushed by the first spring 682 and slides outwards away from the first sliding groove 684. At this time, the first drainage holes 685 are not blocked by the first sliding groove 684 and water starts to flow out.

[0066] Please refer to Figure 8 , inside the second injection pipe 691, there is a third water passage groove 699. On one side of the third water passage groove 699, a second water passage groove 693 is communicated. Outside the third water passage groove 699, there is a second sliding groove 698. Inside the second sliding groove 698, there is a second spring 692. One side of the second spring 692 is fixedly connected to the second injection pipe 691. The other side of the second spring 692 is fixedly connected to a second sliding pipe 696. On one side of the second water passage groove 693, an insertion pipe 697 is fixedly connected. The insertion pipe 697 is fixedly connected to the second injection pipe 691. Inside the second sliding pipe 696, a number of second drainage holes 694 are evenly arranged.

[0067] Specifically, when the water source enters the interior of the second injection pipe 691, it flows into the interior of the second sliding pipe 696 through the third through-water tank 699. Since the second through-water tank 693 is blocked by the second sliding pipe 696, the water source cannot flow into the interior of the insertion pipe 697 at this time. The water source inside the second sliding pipe 696 is ejected from each second drain hole 694 in sequence. When one end of the second sliding pipe 696 is squeezed, the second sliding pipe 696 slides into the interior of the second sliding groove 698, and the second spring 692 is gradually squeezed. When the second spring 692 is completely compressed, the second sliding pipe 696 completely slides into the interior of the second sliding groove 698. At this time, one of the second drain holes 694 is aligned with the second through-water tank 693, and the second drain hole 694 communicates with the second through-water tank 693, and the water source flows into the interior of the insertion pipe 697.

[0068] Please refer to Figures 9-10 , a first water through-hole 6871 is provided inside the rubber plug 687, a fourth through-water tank 6973 is provided inside the insertion pipe 697, a sliding groove 6974 is provided on one side of the fourth through-water tank 6973, a sliding column 6972 is slidably connected inside the sliding groove 6974, and a second water through-hole 6971 and a third water through-hole 6975 are respectively provided inside the insertion pipe 697, and the second water through-hole 6971 is U-shaped.

[0069] Specifically, after the water source flows into the interior of the fourth through-water tank 6973, the sliding column 6972 is impacted by the water pressure and slides outwards, thereby blocking the other end of the second water through-hole 6971. Therefore, the water source flowing into the interior of the second water through-hole 6971 cannot be ejected from the other end.

[0070] When it is necessary to clean the deep circular groove 581, the output end of the first cylinder 61 extends, controlling the first sliding pipe 686 and the second sliding pipe 696 to extend into the interior of the circular groove 581 until one end of the first sliding pipe 686 and the second sliding pipe 696 abuts against the inner wall of the circular groove 581, and the output end of the first cylinder 61 stops extending. The third water pump 64 extracts the water source inside the second water storage bucket and transports it into the interiors of the first sliding pipe 686 and the second sliding pipe 696 respectively, and then sprays out from the first drain hole 685 and the second drain hole 694. At this time, the output end of the second motor 67 rotates clockwise, the first sliding pipe 686 rotates counterclockwise along the center of the second bevel gear 65, and the second sliding pipe 696 rotates clockwise along the center of the third bevel gear 66.

[0071] While rotating, the water flow ejected from the first drain hole 685 drives the iron filings inside the circular groove 581 to flow counterclockwise, and the water flow ejected from the second drain hole 694 drives the iron filings inside the circular groove 581 to flow clockwise. Until the output end of the second motor 67 rotates clockwise by 170 degrees, the rubber plug 687 is inserted into the inside of the insertion tube 697, and the sliding column 6972 is pushed by the rubber plug 687 and slides into the inside of the fourth water passage groove 6973. At this time, one end of the second water hole 6971 is communicated with one end of the first water hole 6871, the other end of the first water hole 6871 is communicated with the third water hole 6975, and the water flow ejected from the first drain hole 685 and the water flow ejected from the second drain hole 694 converge the iron filings inside the circular groove 581 in the middle of the first slide tube 686 and the second slide tube 696.

[0072] Subsequently, the output end of the first cylinder 61 extends again, and the first slide tube 686 and the second slide tube 696 are respectively squeezed into the inside of the first sliding groove 684 and the second sliding groove 698. At this time, all the first drain holes 685 are blocked by the first sliding groove 684 and cannot discharge water. One of the second drain holes 694 is aligned with the second water passage groove 693, and the second drain hole 694 is communicated with the second water passage groove 693. The water source flows into the inside of the insertion tube 697. After the water source flows into the inside of the fourth water passage groove 6973, it passes through the second water hole 6971 and the first water hole 6871 in sequence, and finally flows out from the third water hole 6975. At this time, the direction of the water flow ejection is outward, so as to eject the iron filings converged in the middle of the first slide tube 686 and the second slide tube 696 from the inside of the circular groove 581.

[0073] By respectively rotating the first slide tube 686 counterclockwise and the second slide tube 696 clockwise, the direction of the water flow ejection is adjusted, and then the iron filings inside the circular groove 581 are converged in the middle of the first slide tube 686 and the second slide tube 696. At the end of the convergence, the output end of the first cylinder 61 extends, and the first slide tube 686 and the second slide tube 696 are respectively squeezed into the inside of the first sliding groove 684 and the second sliding groove 698, so that the water source flows into the inside of the fourth water passage groove 6973, and passes through the second water hole 6971 and the first water hole 6871 in sequence, and finally ejects reversely from the third water hole 6975, and ejects the iron filings converged in the middle of the first slide tube 686 and the second slide tube 696 from the inside of the circular groove 581, improving the cleaning speed of the iron filings inside the circular groove 581 and achieving the effect of high cleaning efficiency of the iron filings inside the bearing seat 58.
