Description

Technical Field

[0001] This invention relates to the field of snap ring processing technology, specifically to an automatic cleaning device for snap rings used in rail transit. Background Technology

[0002] Snap rings, also called retaining rings or retaining rings, are a type of fastener used to prevent axial movement of parts on shafts or in holes in machines and equipment. Snap rings used in transportation tracks are small in size. After recycling, the snap rings are cleaned and qualified snap rings are selected for reuse, saving snap ring costs. Unqualified snap rings are replaced with new ones.

[0003] The current method of cleaning snap rings involves placing them in a polishing machine to clean them. However, this method causes some wear and tear on the snap rings, resulting in damage to their surface. Therefore, it is necessary to design an automatic snap ring cleaning device for rail transit.

[0004] Snap ring cleaning is divided into fine cleaning and rough cleaning depending on the type of snap ring. Rough cleaning involves immersing the snap ring in a plastic container containing a metal cleaning agent diluted with water, then rinsing it with water until the spring surface is free of oil and scale. Fine cleaning involves placing the snap ring in an ultrasonic cleaner. If deep cleaning is required, an additional cleaning agent cleaning step is added. The ratio of cleaning agent to water is approximately 1:30. After the spring surface is free of oil and scale, immediately remove it and rinse it with water. The stainless steel spring surface can achieve a matte finish. Summary of the Invention

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 1-10 This invention provides a technical solution: an automatic cleaning device for retaining rings used in rail transit, comprising a high stand 1, a retaining ring housing 2 mounted on the top of the high stand 1, a first electronic scale mounted on the bottom of the retaining ring housing 2, a sorting box 4 and a collection box 3 fixedly installed inside the bottom of the retaining ring housing 2, the sorting box 4 and the collection box 3 sharing a connecting side wall, and a reinforcing block 10 fixedly installed below the connecting side wall, a clamping channel 9 provided below the reinforcing block 10, and a sealing plate 11 slidably mounted inside the reinforcing block 10, the sealing plate 11 being electrically connected to a first driving component, the opening and closing of the clamping channel 9 being controlled by the lifting and lowering of the sealing plate 11, thereby controlling the sorting box 4 and the collection box 3. Whether the collection box 3 is through, a sewage pipe is set at the bottom of the sorting box 4, and the sewage pipe is connected to the sewage tank. A first telescopic rod 28 is set in the bottom area of ​​the inner side wall of the sorting box 4. A first push plate 29 is fixedly connected to the first telescopic rod 28. The first push plate 29 is made of electromagnet. When the first push plate 29 moves, the electromagnet is energized and works. When the first push plate 29 does not move, the electromagnet does not work. When the first push plate enters the center area of ​​the collection box 3, the electromagnet is immediately de-energized, causing the snap ring to fall into the collection box 3. A second telescopic rod 30 is set on the inner side wall of the collection box 3, and a second push plate 31 is set on the second telescopic rod 30.

[0047] The first telescopic rod 28 is electrically connected to the first motor, and the second telescopic rod 30 is electrically connected to the second motor.

[0048] Several processing rods 12 are fixedly installed inside the sorting box 4. Bent pipes 15 are connected to the side walls of the processing rods 12. The bent pipes 15 are connected to square pipes 13. Discharge holes 14 are evenly distributed on the side walls of the square pipes 13. A first solenoid valve is installed at each discharge hole 14. The discharge hole 14 is connected to the bent pipe 15. The bent pipe 15 extends into the processing rods 12 and connects to a cleaning agent tank. The cleaning agent tank is filled with cleaning agent. When cleaning agent needs to be discharged, the first solenoid valve opens, and the cleaning agent is discharged from the cleaning agent tank to the bent pipe 15, and then through the square pipe 13. When the cleaning agent does not need to be discharged, the first solenoid valve is closed. The design of the square tube 13 increases the discharge range of the cleaning agent, preventing the cleaning agent from directly adhering to the retaining spring after it comes out. If the cleaning agent with excessive concentration adheres to the retaining spring for a long time, it will damage the retaining spring. The cleaning agent is released in small amounts at multiple angles, which improves the efficiency of the cleaning agent. The top of the processing rod 12 is provided with an upper discharge hole 16, which is connected to a water source. A second solenoid valve is provided at the upper discharge hole 16. When drainage is needed, the second solenoid valve is opened, and when drainage is not needed, the second solenoid valve is closed.

[0049] A rotating rod 6 is mounted on a bearing in the lower part of the side wall of the processing rod 12. The rotating rod 6 passes through the processing rod 12. A second driving component is provided on the inner side wall of the sorting box 4. The output end of the second driving component is fixedly connected to the rotating rod 6. A rotating hole 5 adapted to the rotating rod 6 is provided on the side wall of the processing rod 12. A waterproof gasket is provided between the rotating hole 5 and the rotating rod 6. A rotating plate 7 is fixedly installed on the side wall of the rotating rod 6. The width of the rotating plate 7 is slightly smaller than the distance between the rotating rod 6 and the inner bottom of the sorting box 4 to maintain rotation. The movement of plate 7 is connected to the rotating rod 6, and the rotating rod 6 is a hollow tube with a pump installed inside. Due to the obstruction of the processing rod 12, the rotating rod 6 has multiple rotating plates 7. Several first guide holes 8 are provided on the rotating plate 7 at one end of the rotating rod 6, and several second guide holes 17 are provided on the rotating plate 7 at the other end. The first guide holes 8 are responsible for water absorption, and the second guide holes 17 are responsible for water drainage. Several filter screens 18 are engaged in the middle section of the rotating rod 6, and magnetic sheets are installed on the filter screens 18.

[0050] The bottom of the collection box 3 is provided with a lower drain pipe 19, which is connected to the discharge pipe 20. The bottom of the discharge pipe 20 is connected to the ultrasonic device 21. A slide rail 22 is fixedly installed on the side wall of the ultrasonic device 21. A slider 23 is slidably installed on the slide rail 22. An electric control rod 24 is provided on the slider 23. A filter plate 25 is fixedly installed on the electric control rod 24. The slider 23 is electrically connected to the third driving component. The electric control rod 24 is electrically connected to the fourth driving component. A collection chamber 27 is provided on one side of the ultrasonic device 21. The collection chamber 27 is used to place the storage box 26. The storage box 26 is used to place the retaining ring.

[0051] The automatic cleaning device is equipped with an automatic cleaning system, which includes an automatic control system and an automatic detection system.

[0052] First, place the snap rings into sorting box 4. The first electronic scale will record the mass of the snap rings in sorting box 4 as M1. Simultaneously, before placing the snap rings, the quantity N of snap rings needs to be input into the automatic cleaning system. The automatic cleaning system then calculates the mass of a single snap ring as M2 = M1 / N. The standard mass of a single snap ring is set as M3, and the error mass is M4. That is, the mass of a single snap ring should be within the range of (M3-M4)-(M3+M4). The automatic cleaning system determines if M2 is within the range of (M3-M4)-(M3+M4). If M2 is not within the range of (M3-M4)-(M3+M4), then this batch of retaining rings is considered qualified. Since the retaining rings are recycled, they will experience wear during use. Retaining rings within the (M3-M4)-(M3+M4) range indicate that the wear is not severe and is within acceptable limits. However, retaining rings outside this range indicate severe wear. For qualified retaining rings, deep cleaning is performed, even if... Two cleaning modes are used: ultrasonic cleaning and cleaning agent cleaning. First, the cleaning agent is used to initially clean the surface of the retaining spring. The cleaning steps are as follows: first, open the upper drain hole 16 and drain clean water into the sorting box 4 through the upper drain hole 16. After the drainage is complete, the cleaning agent is discharged through the liquid outlet hole 14. The purpose of draining water first and then discharging the cleaning agent is to avoid the cleaning agent directly contacting the retaining spring. After the cleaning agent is discharged, the automatic control system drives the second driving component to move. The movement of the second driving component drives the rotating rod 6 to move, which in turn drives the rotating plate 7 to move, thus agitating the retaining spring. The individual snap rings are small in size, but there are many snap rings in the sorting box 4. The snap rings are stirred by the rotating plate 7, which makes the cleaning agent and water mix quickly and improves the cleaning efficiency of the snap rings. The stirring time is set to H. After the stirring time of the rotating plate 7 reaches H, the rotating plate 7 stops moving. This is the cleaning agent cleaning stage of the snap rings. The above process of separating snap rings greatly reduces the snap ring screening process. Since the snap rings themselves are small in size, screening them individually takes too long. At the same time, the price of recycled snap rings is low, so it is necessary to reduce the cost of snap rings in the cleaning process.

[0053] During the agitation of the retaining ring by the rotating plate 7, the first guide hole 8 continuously draws in water and the second guide hole 17 continuously drains water, realizing the water circulation process. During the water circulation process, the water in the sorting box 4 passes through the filter screen 18 in the rotating rod 6. The filter screen blocks the metal waste in the water, improving the water quality in the sorting box 4 and increasing the cleaning efficiency of the retaining ring.

[0054] If the retaining ring is defective, then the above cleaning agent should not be used.

[0055] After the cleaning agent cleaning stage is completed, the sealing plate 11 is in a lowered, bottom-reaching state, sealing the passage 9 and waiting for the cleaning agent cleaning stage to finish. Then, the sewage pipe is opened to discharge the sewage generated from cleaning the retaining springs. The automatic control system drives the sealing plate 11 to rise, opening the passage 9 and then connecting the collection box 3 and the sorting box 4. The automatic control system drives the first telescopic rod 28 to extend, which in turn moves the first push plate 29. The first push plate 29 pushes the retaining springs inside the sorting box 4 towards the passage 9, pushing the retaining springs into the collection box 3. A second electronic scale is installed in the collection box 3 to weigh the retaining springs entering the collection box 3. The mass of the retaining springs entering the collection box 3 each time is set to be within the range of M5-M6. If the mass of the retaining springs entering the collection box 3 is low... At M5, the first push plate 29 continues to move. If the quality of the snap ring entering the collection box 3 is higher than M6, the automatic control system drives the second motor. The second motor drives the second telescopic rod 30 to move. The movement of the second telescopic rod 30 drives the second push plate 31 to move. The second push plate 31 pushes out some snap rings from the collection box 3 until the quality of the snap rings in the collection box 3 is within the range of M5-M6. This achieves the classification of snap ring quality, ensuring that the snap rings discharged in a single operation are within a controllable range, which is convenient for subsequent packaging. Snap rings that are not qualified also need to be classified by quality to remove them from the scope of rough processing and cleaning, which greatly improves the quality of the snap rings. At the same time, qualified and unqualified snap rings are classified and cleaned separately. The selling price of qualified snap rings is different from that of unqualified snap rings, and the processing costs also need to be different to balance the cost.

[0056] Once the quality of the retaining rings in the collection box 3 is determined, the retaining rings enter the discharge pipe 20 through the lower discharge pipe 19 and directly into the ultrasonic equipment 21. The ultrasonic equipment 21 cleans the retaining rings. After the ultrasonic equipment 21 completes the cleaning, the automatic control system drives the slider 23 to rise along the slide rail 22. The rise of the slider 23 drives the filter plate 25 to rise. When the filter plate 25 rises to the top of the slide rail 22, the automatic control system drives the filter plate 25 to rotate upward 180 degrees via the electric control rod 24, sending the retaining rings on the filter plate into the storage box 26. The staff next to the storage box 26 can take out the retaining rings when the box is full and replace it with a new storage box 26. The full storage box 26 then enters the next process through the transmission equipment next to it. Setting the quality division of the retaining rings can avoid the process of manual weight-bearing and manual boxing, and improve the efficiency of retaining ring cleaning and boxing.
