Description

Technical Field

[0001] This invention relates to the field of ultrasonic cleaning technology for motor bearing rings, specifically to an ultrasonic cleaning and rinsing device for bearing rings of new energy vehicle drive motors. Background Technology

[0002] The bearing rings of the drive motor of new energy vehicles are the core load-bearing base of the high-speed bearing in the electric drive system. They are divided into two types of annular hollow precision steel parts: inner ring and outer ring. Together with the rolling elements (steel balls / ceramic balls, rollers), cage, and seals, they form a high-speed bearing assembly that supports the motor rotor shaft.

[0003] After machining processes such as turning and grinding are completed, the bearing rings of new energy vehicle drive motor bearings are often cleaned using traditional single-tank ultrasonic cleaning equipment to remove surface oil and metal debris. The bearing rings have a hollow annular structure, but traditional cleaning equipment only has a single cleaning station. After the workpiece is placed, the bottom is completely in contact with the support tray, creating a cleaning blind spot in the raceway, inner ring, and tray contact area. This blind spot cannot fully receive the ultrasonic cavitation effect. Relying solely on single-sided ultrasonic immersion cleaning is insufficient to completely remove the fine metal powder and stubborn stretching oil embedded in the gaps and grooves of the workpiece. The overall cleanliness of the workpiece is insufficient, making it difficult to meet the high-precision cleaning requirements of new energy drive motor bearings. Summary of the Invention

[0020] The present invention has the following beneficial effects:

[0021] This invention features a frame with two cleaning holes, one at the front and one at the back. The workpiece undergoes single-sided ultrasonic cleaning at the first cleaning station, then flips over using a flipping component and enters the second cleaning station for reverse cleaning. Equipped with a liftable cleaning hood and a seepage tray with a sealing ring, a cylinder lowers the base plate to immerse the workpiece inside the ultrasonic cleaning frame. The cleaning hood completely seals the cleaning chamber, preventing cleaning fluid splashing. In this sealed environment, ultrasonic cavitation effectively removes impurities such as inner and outer diameter rings, fine metal cutting chips from the raceway, and stretching oil stains. The water tank is equipped with a water pump, a diversion pipe, and a retractable extension tube. After cleaning, the water pump draws clean cleaning fluid and delivers it to the inside of the cleaning hood. The rinsing rack uses high-pressure water to thoroughly flush the gaps in the bearing races, removing suspended impurities adhering to the workpiece surface after ultrasonic stripping. The bottom of the ultrasonic cleaning rack is connected to a filter rack via a bottom pipe and a flexible hose. The built-in filter element intercepts metal debris and impurities. A return pump continuously draws cleaning fluid containing impurities and sends it to the filter rack for filtration. The purified liquid is returned to the water tank via a return pipe for reuse, significantly reducing the frequency of cleaning fluid replacement. The flexible hose has a threaded, detachable structure, allowing for quick removal and replacement of the filter element. An automatic telescopic rod controls the raising and lowering of the cleaning hood. During cleaning, the hood presses down to fit the sealing ring of the seepage tray, forming a sealed cavity, preventing spray water from splashing out of the rack.

[0022] The rotating component of this invention features a turntable equipped with a bidirectional electric rod. The moving plates at both ends drive the extrusion plate through the through-hole plate to achieve bidirectional synchronous clamping. This design is suitable for bearing rings of various new energy motors with different inner and outer diameters. The drive device rotates the turntable, rotating plate, and through-hole plate together, completely flipping the bearing rings after single-sided cleaning at the first station. This ensures that the inner side and bottom of the rings, which were not fully in contact with the ultrasonic waves, face upwards, allowing them to be sent to the second cleaning station for deep cleaning on the reverse side. This solves the problem of cleaning dead corners in the annular structure of the bearing rings.

[0023] This invention uses a blower to deliver airflow through a telescopic air pipe. After being heated by a heating device, the airflow enters the spray frame inside the drying hood. An electric rod presses down on the drying hood, forming a sealed drying chamber with a perforated plate with a second sealing ring. High-temperature hot air blows across the bearing race from all directions through the spray frame, quickly evaporating and cleaning residual water stains. At the same time, the airflow impact force blows away adhering water droplets, preventing water stains from forming water spots or scale after drying. This ensures that the workpiece is dry and clean after cleaning and prevents secondary rusting during storage and transportation. A first collection rack is installed at the bottom of the flipping hole, and a second collection rack is installed at the bottom of the drying hole. The two are interconnected by a connecting pipe. All cleaning waste liquid generated by the workpiece flipping and dripping, drying, and blowing falls into the collection rack and is collected into a detachable collection bucket on the outside of the frame through the collection pipe. The waste liquid is collected centrally and does not flow out. The threaded connection of the collection bucket allows for quick disassembly and dumping of the waste liquid, facilitating unified purification and treatment of the waste liquid.

[0024] The present invention's transposition component is equipped with an independent baffle and a transposition plate clamping unit. Relying on an electric push rod to adjust the lateral travel of the telescopic plate and a linear motor to reciprocate longitudinally along the slide rail, it can simultaneously transfer bearing rings at the loading position, the first cleaning hole, the flipping hole, the second cleaning hole, the drying hole, and the unloading position. Each process can be carried out in parallel without waiting for a single batch. It is suitable for batch production line processing of bearing rings for new energy motors. The transposition plate is equipped with a slanted slot frame with an inclined opening. When the electric retraction rod drives the transposition plate to clamp the workpiece, the inclined structure automatically centers and corrects the bearing ring, ensuring that the ring accurately falls in the center position of the water seepage plate, the through hole plate, and the air hole plate, avoiding workpiece displacement that would cause dead corners in ultrasonic cleaning and uneven heating during drying.

[0025] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A perforated plate 64 is fixedly connected to the top of the fixing plate 65, and a sealing ring 66 is fitted onto the surface of the perforated plate 64. An electric rod 67 is fixedly connected to the top of the fixing plate 65, and a drying hood 63 is fixedly connected to the top of the electric rod 67. A spray frame 68 is fixedly connected to the top of the inner wall of the drying hood 63.

The collection rack 69 and the collection rack 71 are connected via a connecting pipe 70, and the end of the collection rack 71 is connected to... A collection pipe 72 is threaded to a collection bucket 73 at one end away from the collection rack 71. A blower 60 delivers airflow through a telescopic air pipe 61. After being heated by a heating device 62, the airflow enters the spray frame 68 inside the drying hood 63. An electric rod 67 presses down on the drying hood, forming a sealed drying chamber with a perforated plate 64 with a sealing ring 66. High-temperature hot air blows the bearing rings from all directions through the spray frame, quickly evaporating and cleaning residual water stains. At the same time, the airflow impact blows away the attached water droplets, preventing water stains from forming water spots and scale after drying.

[0053] The repositioning component 7 includes a telescopic plate 85, the end of which is fixedly connected to the surface of the frame 1. An electric push rod 83 is fixedly connected to the end of the frame 1. The telescopic end of the electric push rod 83 is fixedly connected to the surface of the telescopic plate 85. A slide rail 87 is fixedly connected to the top of the telescopic plate 85. A linear motor 86 is slidably connected to the top of the slide rail 87. A positioning plate 81 is fixedly connected to the top of the linear motor 86. A baffle 80 is fixedly connected to the surface of the positioning plate 81. An electric retraction rod 88 is fixedly connected to the surface of the baffle 80. The telescopic end of the electric retractable rod 88 is fixedly connected to the surface of the shifting plate 82. The shifting component is equipped with 4 sets of independent baffles 80 and shifting plate 82 clamping units. The electric push rod 83 adjusts the lateral travel of the telescopic plate 85, and the linear motor 86 reciprocates longitudinally along the slide rail 87. The bearing rings can be simultaneously transferred at the loading position, the first cleaning hole 8, the flipping hole 9, the second cleaning hole 8, the drying hole 10, and the unloading position. Each process can be carried out in parallel without waiting for a single batch, making it suitable for batch production line processing of bearing rings for new energy motors.

[0054] There are four baffles 80 and four shift plates 82. One baffle 80 and one shift plate 82 form a group. The end of the shift plate 82 is in contact with the surface of the positioning plate 81. The end of the inclined slot frame 84 away from the shift plate 82 is set with an inclined opening.

[0055] In use, the operator places the motor bearing race on top of the feeding conveyor 2, then starts the feeding conveyor 2 to transport the motor bearing race to the designated position. At this time, the feeding conveyor 2 stops operating, and the electric push rod 83 is activated to push the telescopic plate 85 to extend. When the telescopic plate 85 extends, it pulls the baffle 80 and the shifting plate 82 to the outer end of the frame 1. After the position adjustment is completed, the linear motor 86 is activated to move on the surface of the slide rail 87. The linear motor 86 pushes a set of shifting plates 82 and baffles 80 to the feeding conveyor 2. At this time, the electric push rod 83 is activated to push the shifting plates 82 and baffles 80 to the top of the feeding conveyor 2. The electric retraction rod 88 is activated to push the shifting plate 82 towards the baffle 80. When the shifting plate 82 moves, it pushes the inclined slot frame 84 to move. The inclined slot frame 84 and the baffle 80 cooperate to clamp and fix the motor bearing race. The opening of the inclined slot frame 84 is set at an angle, utilizing... The inclined frame 84 adjusts the motor bearing rings to be centered, so that when the shift plate 82 and the baffle 80 push the motor bearing rings, the motor bearing rings will remain aligned with the cleaning hole 8 and the drying hole 10, maintaining the stability of the feeding. After clamping is completed, the linear motor 86 is started to move. When the linear motor 86 moves, it pushes the motor bearing rings to the top of the cleaning hole 8 and into contact with the water seepage plate 35. The shift plate 82 and the baffle 80 are reset by the electric retraction rod 88 and the electric push rod 83. There are four sets of shift plates 82 and baffles 80. The four sets of shift plates 82 and baffles 80 push the motor bearing rings to the top of the cleaning hole 8, the flipping hole 9 and the drying hole 10 through the reciprocating movement of the linear motor 86 for cleaning. Finally, the motor bearing rings at the top of the drying hole 10 will contact the top of the unloading transmission device 3 under the push of the baffle 80. The unloading transmission device 3 is used to unload the cleaned motor bearing rings.

[0056] After the motor bearing race moves to the top of the seepage tray 35, the automatic telescopic rod 25 is activated to push the cleaning hood 22 downwards. As the cleaning hood 22 moves downwards, it pulls the telescopic tube 21 to retract synchronously. After the inner wall of the cleaning hood 22 contacts the sealing ring 36 on the surface of the seepage tray 35, the cleaning hood 22 seals the motor bearing race at the top of the seepage tray 35. At this time, the starting cylinder 27 pushes the connecting plate 23 downwards. As the connecting plate 23 moves downwards, it pushes the base plate 37 into the ultrasonic cleaning frame 29 via the synchronous plate 24. The motor bearing race then enters the ultrasonic cleaning frame 29 along with the base plate 37. The ultrasonic cleaning frame 29 is activated to perform ultrasonic cleaning on the motor bearing race. After the motor bearing race is cleaned, the starting cylinder 27 pushes the base plate 37 back to its original position. After back to its original position, the water pump 26 is activated to transfer the cleaning fluid in the water tank 28 to the diversion pipe 20. The diversion pipe 20 then transfers the cleaning fluid to the telescopic tube 21. In the rinsing rack 34, the cleaning fluid is sprayed out to rinse the motor bearing race, preventing impurities from remaining on the surface of the motor bearing race and affecting the cleaning effect. After cleaning, the automatic telescopic rod 25 is activated to push the cleaning cover 22 to the top of the seepage tray 35, so that the switching plate 82 and the baffle 80 can push the cleaned motor bearing race to the top of the flip hole 9. During operation, the return pump 38 draws the cleaning fluid from the ultrasonic cleaning rack 29 into the filter rack 33, and uses the filter element 32 to filter the cleaning fluid. The filtered cleaning fluid will enter the water tank 28 through the return pipe 39 for recycling. The filter rack 33 is detached from the bottom pipe 30 through the hose 31 so that the filter rack 33 and the filter element 32 can be replaced. During operation, the return pump 38 controls the flow rate of the cleaning fluid to maintain a certain amount of cleaning fluid in the ultrasonic cleaning rack 29 for ultrasonic cleaning of the motor bearing race.

[0057] After the shifting plate 82 and the baffle 80 push the motor bearing ring to the top of the flipping hole 9, the motor bearing ring will contact the surface of the through hole plate 55. At this time, the bidirectional electric rod 51 is activated to pull the two moving plates 54 to move closer to each other. When the moving plates 54 move, they push the pressing plate 56 to clamp and fix the motor bearing ring. After clamping is completed, the drive device 52 is activated to drive the turntable 53 to rotate. When the turntable 53 rotates, it will drive the through hole plate 55 and the pressing plate 56 to rotate. The through hole plate 55 completes a 180-degree rotation to flip the motor bearing ring. After flipping is completed, the bidirectional electric rod 51 is activated to push the pressing plate 56 to retract into the inside of the through hole plate 55. At this time, the shifting plate 82 and the baffle 80 will push the flipped motor bearing ring into the top of the second cleaning hole 8 during operation. The flipped motor bearing ring will be cleaned again by the cleaning component 4 to improve the cleaning effect of the motor bearing ring.

[0058] After the second cleaning, the motor bearing race is pushed to the top of the perforated plate 64 by the shift plate 82 and the baffle 80. The electric lever 67 is activated to push the drying hood 63 downwards. After the drying hood 63 contacts the surface of the perforated plate 64, it seals the motor bearing race to the top of the perforated plate 64. The heating device 62 is then activated to begin operation. The airflow generated by the blower 60 enters the spray gun 68 through the heating device 62. The spray gun 68 sprays the airflow onto the surface of the motor bearing race, using the airflow to wash away water stains on the surface of the motor bearing race. The airflow is then amplified... After the heating device 62 heats the motor bearing rings, the airflow enters the drying hood 63 and dries the bearing rings. This prevents water stains from remaining on the surface of the bearing rings after cleaning and prevents impurities from adhering to the surface of the bearing rings during transportation, which would affect the cleaning effect. A collection rack 69 and a collection rack 71 are provided at the bottom of the flip hole 9 and the bottom of the drying hole 10, respectively. The collection racks 69 and 71 are used to collect the residual cleaning fluid on the bearing rings. The collected cleaning fluid then enters the collection tank 73 through the collection pipe 72.
