Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment, and in particular to a cleaning device for pretreatment of metal workpieces. Background Technology

[0002] As people's living standards improve, they are spending more and more on cars, and the market for auto parts is growing larger and larger. In recent years, auto parts manufacturers have also been developing rapidly.

[0003] Currently, after the processing and manufacturing of some conventional auto parts, the outer surface of the metal workpieces is often covered with oil and metal shavings. Therefore, the metal workpieces usually need to be cleaned after processing to avoid contaminants such as metal shavings and oil affecting the quality of the auto parts.

[0004] While existing mechanical cleaning equipment has improved cleaning efficiency to some extent, it still suffers from numerous problems. On one hand, key parameters in the workpiece cleaning process, such as the temperature of the cleaning solution, the cleaning method, and the cleaning intensity, lack precise control. For example, some cleaning equipment, when using ultrasonic cleaning, cannot flexibly adjust the frequency and power of the ultrasonic waves, nor can it be optimized according to different metal materials and types of dirt, resulting in poor cleaning effects, stubborn residues, and impacts on the surface quality and subsequent processing performance of the metal workpieces. Furthermore, most traditional equipment also has deficiencies in the drying stage after cleaning. Some equipment relies solely on natural air drying or simple hot air devices for drying, resulting in low drying efficiency. Moreover, due to the lack of effective guidance and uniform distribution of hot air, localized overheating or undercooling is prone to occur, causing deformation and cracking of the metal workpieces during drying due to uneven temperature, severely affecting the product qualification rate. Therefore, to address these problems, a pre-treatment cleaning device for metal workpieces is proposed. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a cleaning device for pretreatment of metal workpieces, comprising a cleaning cabinet 1 and a placement net 19. An ultrasonic cleaning tank 2 is located on the left side inside the cleaning cabinet 1. The ultrasonic cleaning tank 2 utilizes high-frequency vibrations generated by ultrasonic waves to clean the metal workpieces placed in the placement net 19. Through the cavitation effect generated by the high-frequency vibrations, dirt and impurities on the surface of the metal workpieces are removed, achieving the purpose of cleaning. It is the core component for cleaning metal workpieces. A cleaning tank adjustment screen 3 is located on the front side of the cleaning cabinet 1. The cleaning tank adjustment screen 3 serves as a control interface, allowing operators to adjust the parameters of the cleaning fluid inside the cleaning cabinet 1, such as the temperature of the cleaning fluid, the frequency and power of the ultrasonic waves.

[0033] A placement platform 4 is located on the side of the cleaning cabinet 1 furthest from the adjustment screen 3 in the cleaning tank. The placement platform 4 is used to place the metal workpieces to be cleaned. A motor 5 is fixedly connected to the top left side of the cleaning cabinet 1. A threaded rod 6 is fixedly connected to the drive end of the motor 5. The motor 5 drives the threaded rod 6 to rotate, providing power for the movement of components such as the slider 7 and the hydraulic telescopic rod 8. The outer part of the threaded rod 6 is rotatably connected to the inner top of the cleaning cabinet 1, and both ends of the threaded rod 6 are rotatably connected to the inner top of the cleaning cabinet 1 through bearings and other components to ensure stable rotation.

[0034] refer to Figure 2 , Figure 3The threaded rod 6 is externally threaded with a slider 7, which is threadedly connected to the threaded rod 6. When the threaded rod 6 rotates, the slider 7 can move linearly along the threaded rod 6. Two hydraulic telescopic rods 8 are fixedly connected to the bottom end of the slider 7, and a support plate 9 is fixedly connected to the bottom end of the two hydraulic telescopic rods 8. After reaching the designated position driven by the slider 7, the hydraulic telescopic rods 8 can adjust their position by extending and retracting, thereby driving the rotating rod 10 and the clamping rod 11 on the support plate 9.

[0035] Two rotating rods 10 are rotatably connected to the top left and right sides of the support plate 9. Clamping rods 11 are rotatably connected to the bottom of each rotating rod 10. The support plate 9 connects to the clamping rods 11. A rotating shaft 12 is fixedly connected to the middle of the two clamping rods 11, and a driven bevel gear 13 is fixedly connected to the middle of the rotating shaft 12. The driven bevel gear 13 is fixed, allowing the two clamping rods 11 to rotate relative to each other. Driven by the motor 17 and the driving bevel gear 18, the rotating shaft 12 drives the two clamping rods 11 to rotate crosswise via the driven bevel gear 13, thus achieving the clamping and releasing action of the collar 20.

[0036] A drive assembly is provided in the middle of the front and rear sides of the support plate 9. The drive assembly includes two rotating rollers 14. The top ends of the two rotating rollers 14 are rotatably connected to the middle of the front and rear sides of the support plate 9. The bottom ends of the rotating rollers 14 are fixedly connected to rotating rollers 15. The rotating rollers 14 are installed in the middle of the front and rear sides of the support plate 9 as support and rotation components. Together with the rotating rollers 15, they form a support structure to provide rotational support for components such as the protective shell 16, ensuring that the protective shell 16 and its internal components can rotate flexibly, while also assisting in supporting the structure of the entire device.

[0037] A protective shell 16 is fixedly connected to the bottom end of the rotating roller 15. The external shaft 12 is rotatably connected to the middle of the protective shell 16. The protective shell 16 protects components such as the motor 17 and the driving bevel gear 18 from damage caused by external factors, while providing them with a relatively enclosed working environment to ensure the normal operation of the motor 17 and the stability of power transmission. The motor 17 is fixedly connected to the top end of the protective shell 16. The driving end of the motor 17 is fixedly connected to the driving bevel gear 18. The external teeth of the driving bevel gear 18 are meshed with the external teeth of the driven bevel gear 13. Two collars 20 are fixedly connected to the top end of the placement net 19. The bottom ends of the two clamping rods 11 engage with the outside of the collars 20. The motor 17 drives the driving bevel gear 18 to rotate, providing power for the rotation of the clamping rods 11, realizing precise clamping operation of the placement net 19, and ensuring that the clamping rods 11 can stably clamp the collars 20 during the lifting and moving of the placement net 19.

[0038] refer to Figure 2 , Figure 4 An air outlet pipe 21 is fixedly connected to the side of the cleaning cabinet 1 away from the motor 5. A hot air blower 22 is installed in the middle of the air outlet pipe 21. The air outlet pipe 21 is a channel for hot air delivery, which delivers the hot air generated by the hot air blower 22 into the cleaning cabinet 1 for drying the cleaned metal workpieces, accelerating the evaporation of moisture on the surface of the metal workpieces, and ensuring the drying effect of the cleaned metal workpieces.

[0039] A frame 23 is fixedly connected to the side of the air outlet duct 21 near the cleaning cabinet 1. Multiple rollers 24 are rotatably connected to the middle of the frame 23. A guide plate 25 is fixedly connected to the outside of the rollers 24. A roller 26 is fixedly connected to the side of the guide plate 25 near the hot air blower 22. A connecting plate 27 is rotatably connected to the outside of the multiple rollers 26. A protrusion 28 is fixedly connected to the middle of the connecting plate 27. The frame 23 provides installation positions and support for components such as rollers 24, guide plate 25, rollers 26, and connecting plate 27, while limiting the sliding range of the guide plate 25 so that the guide plate 25 can slide inside it and guide the flow direction of hot air.

[0040] A reciprocating pump 29 is installed at the rear center of the frame 23. The top of the reciprocating pump 29 is slidably connected to the bottom of the protrusion 28. The outer side of the air guide plate 25 is slidably connected to the inner wall of the frame 23. A telescopic component 30 is fixedly connected to the drive end of the reciprocating pump 29. The reciprocating pump 29 is the driving component, driving the protrusion 28 to reciprocate, which in turn drives the air guide plate 25 to swing back and forth. By changing the flow direction of hot air, the cleaning of the metal workpiece is fully dried. A transparent baffle curtain 31 is installed in the middle of the cleaning cabinet 1. The transparent baffle curtain 31 is installed in the middle of the cleaning cabinet 1. On the one hand, it can prevent the disorderly flow of cleaning fluid and hot air in the cleaning cabinet 1, ensuring the orderly progress of the cleaning and drying process. On the other hand, due to its transparency, it is convenient for operators to observe the internal cleaning and drying situation.

[0041] Working principle: In use, the metal workpiece is placed in the placement net 19. First, the water in the cleaning cabinet 1 is made to vibrate at high frequency by adjusting the screen 3 of the cleaning tank. Then, the external control system starts the motor 5 to drive the threaded rod 6 to rotate, which in turn drives the slider 7 and the hydraulic telescopic rod 8 to move. When the slider 7 moves onto the placement net 19, the hydraulic telescopic rod 8 is activated to extend and retract, which drives the rotating rod 10 and the clamping rod 11 fixed on the support plate 9 to move the collar 20 of the placement net 19. Then, the motor 17 is activated to drive the active bevel gear 18 to rotate and mesh with the driven bevel gear 13 of the rotating shaft 12. The driven bevel gear 13 rotates, which drives the clamping rod 11 fixed on the rotating shaft 12 to clamp relatively in the center until the rotating shaft 12 crosses and rotates into the collar 20. At this time, the hydraulic telescopic rod 8 can be activated again to activate the clamping rod 11 to clamp and lift the placement net 19. The placement net 19 is then lifted by the threaded rod 6 and moved to the position of the ultrasonic cleaning tank 2 before being lowered for placement. At this time, the ultrasonic cleaning tank 2 will perform high-frequency vibration cleaning on the metal workpiece placed in the net 19.

[0042] After cleaning, the hydraulic telescopic rod 8 is activated again to drive the clamping rod 11 to lift the placement net 19 to the top of the ultrasonic cleaning tank 2 for suspension. At this time, the hot air blower 22 is activated to blow warm air into the top of the ultrasonic cleaning tank 2 through the air outlet 21. Then, the reciprocating pump 29 is activated to drive the telescopic component 30 to slide back and forth, so that the telescopic component 30 slides on one side of the protrusion 28. Under the reciprocating extension and retraction of the protrusion 28 and the telescopic component 30, the air guide plate 25 is driven by the connecting plate 27 and the second shaft roller 26 to swing around the first shaft roller 24, so that the evenly cooled air is dispersed into the inner cavity of the cleaning cabinet 1, ensuring that the metal workpieces in the placement net 19 can be evenly dried after cleaning.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
