Description

Technical Field

[0001] This utility model relates to the field of oil-impregnated bearing cleaning technology, and more specifically, to an automatic cleaning device for powder metallurgy oil-impregnated bearings. Background Technology

[0002] Powder metallurgy oil-impregnated bearings are a common type of mechanical part. They are bearings with self-lubricating properties, using internal or external lubricating oil or grease to achieve self-lubrication during operation. However, during the manufacturing process, their surfaces may retain impurities such as oil stains and metal shavings generated during processing. These impurities can affect the performance and service life of the oil-impregnated bearings. Therefore, after the powder metallurgy oil-impregnated bearings are manufactured, they need to be cleaned.

[0003] In existing facilities, after the oil-impregnated bearings are cleaned, they need to be taken to a designated location for drying, which makes it impossible to integrate cleaning and drying, thus reducing the production efficiency of oil-impregnated bearings.

[0004] A search revealed that Chinese Patent CN222132840U discloses an oil-impregnated bearing cleaning device. In this device, activating a hot air blower allows hot air to be blown out from the air outlet, drying the cleaned oil-impregnated bearing workpieces within the cleaning frame. During this process, activating a first lifting device causes the cleaning frame to reciprocate up and down a short distance, causing the oil-impregnated bearing workpieces within the frame to vibrate. Activating a second lifting device causes the air outlet plate to reciprocate up and down a short distance, further improving the drying efficiency of the oil-impregnated bearing workpieces. This integrated cleaning and drying process enhances the production efficiency of oil-impregnated bearings.

[0005] However, in actual use, the structure involves activating the first lifting device to move the cleaning frame back and forth within the cleaning tank. This causes the cleaning fluid in the tank to come into contact with the oil-impregnated bearing workpieces within the cleaning frame for cleaning. The oil-impregnated bearing workpieces accumulate within the cleaning frame and are cleaned in one go during the back and forth movement. The rinsing force and time received by different parts may vary, making it difficult to effectively remove stubborn stains, resulting in incomplete and uneven cleaning. Utility Model Content

[0035] Next, the water pump 18 is turned on. The water pump 18 works to draw out the cleaning liquid in the cleaning liquid tank 15 through the L-shaped tube 17. The cleaning liquid enters the distribution frame 13 through the L-shaped tube 17, and then is evenly sprayed into the interior of the cleaning frame 11 through multiple spray nozzles 14 at the bottom of the distribution frame 13. Moreover, multiple through holes are opened on the surface of the cleaning frame 11, and the cleaning liquid flows into the interior of the first cleaning chamber 3 through the through holes.

[0036] Meanwhile, the electric telescopic rod 8 can extend and retract. Through the extension and retraction of the electric telescopic rod 8, the L-shaped fixed frame 9 and the cleaning frame 11 can be moved up and down. In this way, the powder metallurgy oil-impregnated bearing in the cleaning frame 11 can move in the cleaning box 1, so that the bearing can fully contact the sprayed cleaning liquid and achieve the purpose of cleaning.

[0037] Reference Figure 2-4 As shown, a cleaning liquid tank 15 is fixedly installed on one side of the cleaning tank 1, a first liquid inlet pipe 16 is provided through one side of the cleaning liquid tank 15, an L-shaped pipe 17 is provided through the top of the cleaning liquid tank 15, a water pump 18 is fixedly installed on one side of the L-shaped pipe 17, and one end of the L-shaped pipe 17 passes through the support frame 12 and is connected to the distribution frame 13.

[0038] The surface of the cleaning frame 11 is provided with a connecting groove, and a plug 19 is inserted into the inside of the connecting groove. The plug 19 is connected to the L-shaped fixing frame 9 by bolts. The surface of the cleaning frame 11 is provided with multiple through holes.

[0039] Place the powder metallurgy oil-impregnated bearing that needs to be cleaned into the cleaning frame 11, check whether there is enough cleaning liquid in the cleaning liquid tank 15, if not, add cleaning liquid through the first liquid inlet pipe 16, and add cleaning liquid into the second cleaning chamber 4 through the second liquid inlet pipe 29.

[0040] The powder metallurgy oil-impregnated bearing is placed in the cleaning frame 11, and the insert block 19 is connected to the L-shaped fixing frame 9 by bolts to fix the cleaning frame 11. The collection mesh frame 28 is inserted into the mounting groove on the surface of the cleaning box 1 and the partition plate 2 to collect impurities generated during the cleaning process.

[0041] Reference Figure 3-5 As shown, a drying mechanism is provided on one side of the cleaning box 1. The drying mechanism includes a stabilizing plate 20 fixedly installed on one side of the cleaning box 1. A hot air blower 21 is fixedly installed on one side of the stabilizing plate 20. A conveying pipe 22 is fixedly installed at the output end of the hot air blower 21. An air guide frame 23 is provided through one end of the conveying pipe 22.

[0042] Multiple air outlets 24 are provided through one side of the air guide frame 23. One side of the air guide frame 23 is connected to the stabilizing plate 20.

One end of the threaded rod 26 is rotatably connected to the inner wall of the slide groove 5. The threaded rod 26 is threadedly connected to the I-beam slide bar 10.

[0043] Start the stepper motor 25, which drives the threaded rod 26 to rotate. Since the threaded rod 26 is threadedly connected to the I-beam slide bar 10 and the slider 6 slides in the slide groove 5, when the threaded rod 26 rotates, it will drive the I-beam slide bar 10 to move along the threaded rod 26, thereby driving the cleaning frame 11 to move laterally in the cleaning box 1.

[0044] Until the cleaning frame 11 moves to the top of the second cleaning chamber 4, the electric telescopic rod 8 is then activated to adjust the height of the cleaning frame 11 as needed, driving the cleaning frame 11 to move downwards until the oil-impregnated bearing inside the cleaning frame 11 is fully immersed in the cleaning fluid in the second cleaning chamber 4. Through multiple through holes on the surface of the cleaning frame 11, the cleaning fluid is allowed to fully contact the bearing, thus achieving cleaning.

[0045] Reference Figure 5-6 As shown, multiple support legs 27 are fixedly installed at the bottom of the cleaning tank 1. The surfaces of the cleaning tank 1 and the partition 2 are provided with mounting grooves. A collection mesh frame 28 is inserted into the inside of the mounting groove. A handle is fixedly installed on one side of the collection mesh frame 28.

[0047] Restart the electric telescopic rod 8 to move the cleaning frame 11 to the corresponding position of the drying mechanism, that is, close to the air guide frame 23. Then start the hot air blower 21. The hot air generated by the hot air blower 21 is delivered to the air guide frame 23 through the conveying pipe 22. The hot air is then blown out through multiple air outlets 24 on one side of the air guide frame 23 to dry the powder metallurgy oil-impregnated bearing in the cleaning frame 11. Then take out the cleaned and dried powder metallurgy oil-impregnated bearing in the cleaning frame 11.

[0048] Wastewater generated during the cleaning process flows out through the outlet pipe 30 at the bottom of the first cleaning chamber 3 and the second cleaning chamber 4. The solenoid valve on the surface of the outlet pipe 30 controls the opening and closing of the outlet pipe 30. When it is necessary to discharge wastewater, the solenoid valve is opened and the wastewater can be discharged. In addition, the collection mesh frame 28 installed in the groove on the surface of the cleaning tank 1 and the partition 2 can collect the impurities that fall off during the cleaning process, making it convenient to clean.

[0049] Working principle of this utility model:

[0050] This utility model is an automatic cleaning device for powder metallurgy oil-impregnated bearings. When using the device, firstly, the powder metallurgy oil-impregnated bearing to be cleaned is placed in the cleaning frame 11. Check whether there is enough cleaning liquid in the cleaning liquid tank 15. If not, add cleaning liquid through the first liquid inlet pipe 16 and add cleaning liquid into the second cleaning chamber 4 through the second liquid inlet pipe 29.

[0051] Place the powder metallurgy oil-impregnated bearing in the cleaning frame 11, and connect the insert block 19 to the L-shaped fixing frame 9 with bolts to fix the cleaning frame 11. Insert the collection mesh frame 28 into the mounting groove on the surface of the cleaning box 1 and the partition plate 2 to collect impurities generated during the cleaning process.

[0052] Next, the water pump 18 is turned on. The water pump 18 works to draw out the cleaning liquid in the cleaning liquid tank 15 through the L-shaped tube 17. The cleaning liquid enters the distribution frame 13 through the L-shaped tube 17, and then is evenly sprayed into the interior of the cleaning frame 11 through multiple spray nozzles 14 at the bottom of the distribution frame 13, thereby rinsing the dirt on the surface of the powder metallurgy oil-impregnated bearing. In addition, multiple through holes are opened on the surface of the cleaning frame 11, and the cleaning liquid flows into the interior of the first cleaning chamber 3 through the through holes.

[0053] Meanwhile, the electric telescopic rod 8 can extend and retract. Through the extension and retraction of the electric telescopic rod 8, the L-shaped fixed frame 9 and the cleaning frame 11 can be moved up and down. In this way, the powder metallurgy oil-impregnated bearing in the cleaning frame 11 can move in the cleaning box 1, so that the bearing can fully contact the sprayed cleaning liquid and achieve the purpose of cleaning.

[0054] Then start the stepper motor 25. The stepper motor 25 drives the threaded rod 26 to rotate. Since the threaded rod 26 is threadedly connected to the I-beam slide bar 10 and the slider 6 slides in the slide groove 5, when the threaded rod 26 rotates, it will drive the I-beam slide bar 10 to move along the threaded rod 26, thereby driving the cleaning frame 11 to move laterally in the cleaning box 1.

[0055] Until the cleaning frame 11 moves to the top of the second cleaning chamber 4, then the electric telescopic rod 8 is activated to adjust the height of the cleaning frame 11 as needed, and the cleaning frame 11 is moved downward until the oil-impregnated bearing inside the cleaning frame 11 is fully immersed in the cleaning fluid in the second cleaning chamber 4. Through multiple through holes on the surface of the cleaning frame 11, the cleaning fluid is allowed to fully contact the bearing to achieve cleaning.

[0056] After cleaning is completed, the electric telescopic rod 8 is activated again to move the cleaning frame 11 to the corresponding position of the drying mechanism, that is, the position close to the air guide frame 23. Then the hot air fan 21 is activated. The hot air generated by the hot air fan 21 is delivered to the air guide frame 23 through the conveying pipe 22. The hot air is then blown out through multiple air outlets 24 on one side of the air guide frame 23 to dry the powder metallurgy oil-impregnated bearing in the cleaning frame 11. Then the cleaned and dried powder metallurgy oil-impregnated bearing in the cleaning frame 11 can be taken out.

[0057] Wastewater generated during the cleaning process flows out through the outlet pipe 30 at the bottom of the first cleaning chamber 3 and the second cleaning chamber 4. The solenoid valve on the surface of the outlet pipe 30 controls the opening and closing of the outlet pipe 30. When it is necessary to discharge wastewater, the solenoid valve is opened and the wastewater can be discharged. In addition, the collection mesh frame 28 installed in the groove on the surface of the cleaning tank 1 and the partition 2 can collect the impurities that fall off during the cleaning process, making it convenient to clean.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
