Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valve production, and specifically relates to an oil immersion device for hydraulic valve production. Background Technique

[0002] A hydraulic valve is an automated component operated by pressure oil. It is controlled by the pressure oil of a distribution valve and is usually used in combination with an electromagnetic distribution valve. It can be used to remotely control the on-off of the oil, gas, and water pipeline systems of a hydropower station and is commonly used in oil circuits such as clamping, control, and lubrication. Currently, existing hydraulic valves need to be immersed in oil during the production process. On the one hand, this can clean the produced hydraulic valve housing, and on the other hand, it can perform rust prevention treatment on the hydraulic valve housing. However, the traditional operation method mostly involves manually putting the hydraulic valve housing into an oil barrel and then manually taking it out after a certain period of time. The operation of taking and placing materials is very troublesome, and the working effect is naturally relatively low.

[0003] To solve the above problems, a prior patent (Publication No.: CN220658118U) provides an oil immersion device for producing hydraulic valves. By installing a stop bar on the support rod, when the placement box enters the immersion oil for soaking and is conveyed by the chain conveyor, the placement box can be tilted by being blocked, thereby realizing the export of the hydraulic valve, effectively reducing the cost of manual operation.

[0004] However, during the use of the hydraulic valve oil immersion device in the above-mentioned published document, when the hydraulic valves are squeezed and piled up inside the placement box, there will be certain oil immersion dead corners, which will have a certain impact on the oil immersion work of the hydraulic valves. At the same time, it is slower to filter the excess oil on the surface of the hydraulic valves, indirectly reducing the oil immersion efficiency of the device.

[0005] Therefore, the technical personnel in this field have provided an oil immersion device for hydraulic valve production to solve the problems raised in the above background technique. Content of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, the embodiment of the utility model provides an oil immersion device for hydraulic valve production. By setting an activity mechanism, the hydraulic valves can be continuously shaken during the oil immersion process to avoid the formation of dead corners due to the accumulation of hydraulic valves, resulting in insufficient oil immersion and affecting the subsequent use of the hydraulic valves. Secondly, by setting a rotatable bottom plate, the hydraulic valves that have completed oil immersion can be automatically poured out of the placement box without manual operation by the staff, saving time and effort. Finally, by setting a separation mechanism, the excess oil on the surface of the hydraulic valves can be quickly separated, and at the same time, by setting a pump, the separated oil can be recycled, facilitating recycling, so as to solve the problems raised in the above background technique.

[0007] To achieve the above object, the utility model provides the following technical solutions:

[0022] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, an oil - immersion device for the production of hydraulic valves includes an oil - immersion tank 1. The inside of the oil - immersion tank 1 is used for placing oil. The upper end of the oil - immersion tank 1 is connected to a driving frame 3 through two support columns 2. The driving frame 3 is connected to a placing box 5 through a connecting bar 4. The connecting bar 4 and the placing box 5 are in sliding connection. Two cylinders are arranged on the driving frame 3, one for driving the placing box 5 to move horizontally and the other for driving the placing box 5 to move vertically. The inside of the placing box 5 is used for placing the hydraulic valves to be oil - immersed. The oil - immersion tank 1 is connected to an external box 7 through a pump 6. The external box 7 is used for storing the oil - immersed hydraulic valves and the redundant oil. Through the pump 6, the oil can be re - discharged into the oil - immersion tank 1 for recycling.

[0023] The lower end of the placement box 5 is connected to a bottom plate 17 through a rotating shaft 16. The bottom plate 17 is made of iron and is used to close the placement box 5. A plurality of circulation holes 18 are provided on the bottom plate 17 to facilitate the outflow of oil from the inside of the placement box 5. One end of the bottom plate 17 is connected to the placement box 5 through a spring 19. Under the action of the spring 19, the bottom plate 17 closes the bottom of the placement box 5. A chute 20 is provided on one side of the bottom plate 17. The upper end of the immersion oil tank 1 is connected to a slide bar 21. When the placement box 5 moves to contact the slide bar 21 under the action of the driving frame 3, the bottom plate 17 will rotate through the rotating shaft 16 to open the lower end of the placement box 5, facilitating the pouring out of the internal hydraulic valve.

[0024] A driving motor 8 is provided outside the outer wall of the immersion oil tank 1. A first gear 9 is connected to the output shaft of the driving motor 8. A chain 10 is engaged with the first gear 9. When the driving motor 8 works, it will drive the first gear 9 to rotate, thereby synchronously rotating the chain 10. The immersion oil tank 1 is also rotatably connected to a second gear 11 engaged with the chain 10. A reciprocating lead screw 12 is fixedly connected to the second gear 11. A moving strip 13 is sleeved on the reciprocating lead screw 12. A magnet 14 is embedded in the upper end of the moving strip 13. When the second gear 11 rotates driven by the chain 10, it will drive the reciprocating lead screw 12 to rotate synchronously. Under the action of the limiting rod 15, the moving strip 13 will move back and forth reciprocally. When the placement box 5 is inside the immersion oil tank 1, the magnet 14 will tightly adhere to the bottom plate 17, thereby driving the placement box 5 to move back and forth based on the connecting strip 4 to achieve full immersion of the hydraulic valve in oil.

[0025] A square box 28 is slidably connected inside the external box 7. An activity frame 30 is arranged inside the square box 28. A filter screen 31 is arranged inside the activity frame 30. The filter screen 31 is used to place the hydraulic valve after immersion in oil, and can filter the hydraulic valve after immersion in oil again to make the excess oil on its surface flow out. A pull ring 32 is connected to the activity frame 30. The activity frame 30 can be quickly removed from the square box 28 through the pull ring 32 to process the hydraulic valve after immersion in oil.

[0026] The external box 7 is rotatably connected to a third gear 22 engaged with the chain 10. A limiting column 23 is fixedly connected to the third gear 22. A moving frame 24 is sleeved on the limiting column 23. The moving frame 24 is connected to the square box 28 through a connecting rod 25. When the third gear 22 rotates under the action of the chain 10, it will drive the square box 28 to move reciprocally to facilitate the discharge of excess oil.

[0027] The working principle of the present utility model is as follows: When it is necessary to immerse the hydraulic valve in oil, first, the hydraulic valve needs to be placed inside the placement box 5. Then, under the action of the driving frame 3, the placement box 5 moves downward into the immersion oil tank 1. The oil inside the immersion oil tank 1 will enter the placement box 5 through the circulation holes 18, enabling the hydraulic valve to be fully in contact with the oil. Then, the driving motor 8 starts to work, driving the first gear 9 to rotate synchronously. Under the action of the chain 10, the second gear 11 will rotate synchronously with the first gear 9. When the second gear 11 rotates, it drives the reciprocating lead screw 12 to rotate. Under the action of the limiting rod 15, it drives the moving strip 13 to move back and forth. At this time, the magnet 14 tightly adheres to the bottom plate 17, and the moving strip 13 drives the placement box 5 to move synchronously, shaking the hydraulic valve inside to prevent the hydraulic valve from piling up and causing insufficient oil immersion. After the oil immersion is completed, the placement box 5 moves upward to its original position, and then moves horizontally under the action of the driving frame 3. When the placement box 5 drives the bottom plate 17 to move into contact with the sliding rod 21, under the action of the sliding groove 20, it will push the bottom plate 17 to rotate through the rotating shaft 16, thus pouring out the hydraulic valve inside the placement box 5, making it fall on the filter screen 31 of the movable frame 30. The filter screen 31 will filter the excess oil on the surface. At this time, under the action of the chain 10, the third gear 22 rotates synchronously, driving the limiting column 23 to rotate, and then pushing the moving frame 24 and the connecting rod 25 to perform horizontal reciprocating motion, driving the square frame 28 to move back and forth, accelerating the filtration of the oil on the surface of the hydraulic valve. After completion, the movable frame 30 is taken out through the pull ring 32, and the hydraulic valve can be processed. The filtered oil will re-enter the immersion oil tank 1 through the pump 6 for recycling.

[0028] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
