Description

Technical Field

[0001] The present invention relates to the field of drive shaft constant velocity joint processing, and particularly to an ultrasonic cleaning and processing device for automotive drive shaft constant velocity joints. Background Art

[0002] In the automotive manufacturing and repair industries, the automotive drive shaft constant velocity joint, as a key transmission component, its cleanliness has a crucial impact on performance and service life. Traditional cleaning methods often use static immersion or simple spraying methods. Although these methods can remove some dirt, it is difficult to ensure the overall cleanliness of the workpiece surface;

[0003] Especially in the cleaning of workpieces such as automotive drive shaft constant velocity joints with complex structures, numerous small gaps, and uneven surfaces, static immersion easily causes the cleaning liquid to remain in the gaps, while simple spraying is difficult to ensure that the cleaning liquid can fully penetrate into every detail part. These problems not only affect the cleaning effect but may also cause quality problems during subsequent processing or use. Therefore, it is necessary to consider how to solve the above problems. Summary of the Invention

[0008] Preferably, the shaking mechanism includes a U-shaped frame fixedly connected to the lower end of the net cage. A plate-shaped electromagnet is installed on the horizontal part of the U-shaped frame. A slidable shaking plate is arranged in each placement space. Each shaking plate is made of ferroalloy, and the lower end of each shaking plate is elastically connected to the bottom in the corresponding placement space through a plurality of third springs.

[0009] Preferably, a sector-shaped conductive plate is installed on the output shaft of the driving motor. An L-shaped bar is fixedly connected to the rear side of the horizontal plate, and two power connection plates are symmetrically and fixedly connected to the front side of the vertical part of the L-shaped bar.

[0010] Preferably, the two power connection plates are respectively located above and below the sector-shaped conductive plate, and the two power connection plates cooperate with the plate-shaped electromagnet.

[0011] Preferably, the liquid flushing mechanism includes a piston cylinder fixedly connected to the upper end of the horizontal plate. A second piston plate that can slide back and forth is arranged in the piston cylinder. The front side of the second piston plate is elastically connected to the front inner wall of the piston cylinder through a second spring. A round-headed abutting rod is fixedly connected to the rear side of the second piston plate. A cam is fixedly connected to the output shaft of the driving motor, and the cam abuts against the round-headed abutting rod.

[0012] Preferably, the front side space of the piston cylinder communicates with a first one-way pipe and a second one-way pipe. Check valves are installed inside the first one-way pipe and the second one-way pipe. A liquid storage cylinder is fixedly connected to the rear side of the connecting bar. A first piston plate that slides up and down is arranged in the liquid storage cylinder. The lower end of the first piston plate is elastically connected to the inner bottom of the liquid storage cylinder through a first spring. The inner bottom of the liquid storage cylinder communicates with the outside through a through port. A hollow plate is fixedly connected to the front side of the connecting bar. A plurality of liquid discharge holes are formed in the inner bottom of the hollow plate. The other end of the first one-way pipe communicates with the inner top space of the liquid storage cylinder. The inner top space of the liquid storage cylinder communicates with the hollow plate through a release pipe.

[0013] Preferably, a mounting post is installed at the inner bottom of the liquid storage cylinder. A touch delay switch is installed at the upper end of the mounting post. A normally closed solenoid valve is installed in the release pipe, and the normally open solenoid valve is electrically connected to the touch delay switch.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. After the device is started, the ultrasonic component in the ultrasonic cleaning tank generates ultrasonic vibrations, which cooperate with the cleaning liquid to form an ultrasonic cleaning environment. The automotive drive shaft ball cage to be cleaned is placed on the vibrating plate in the wire mesh box. The wire mesh box is driven by a driving motor to move up and down, immersing the workpiece in the cleaning liquid. During the ultrasonic cleaning process, the vibrating plate and the workpiece on it generate up and down vibrations, which promote the full contact between the cleaning liquid and the workpiece surface, significantly improving the cleaning effect.

[0016] 2. During the process of the wire mesh box moving down and then up, the rotation of the driving motor cooperates with the cam and the round head push rod to push the piston plate to slide back and forth in the piston cylinder, realizing automatic water supply and liquid storage. When the piston plate moves backward, a negative pressure is formed in the piston cylinder, and clear water is sucked in from the external clear water tank through the second one-way pipe; when the piston plate moves forward, the clear water is compressed and enters the liquid storage cylinder, preparing for the subsequent flushing step. When the workpiece moves up as a whole to a position higher than the cleaning liquid level, the piston plate just moves down to just touch the touch delay switch. At this time, both the normally open solenoid valve and the normally closed solenoid valve are energized. The clear water in the liquid storage cylinder enters the hollow plate through the release pipe and sprays out from multiple drain holes at its inner bottom, precisely flushing the raised workpiece. This flushing method ensures that the cleaning liquid and impurities on the workpiece surface are thoroughly flushed away.

[0017] 3. During the flushing process, the vibrating mechanism continues to work, causing the vibrating plate and the workpiece on it to generate up and down vibrations. This vibration helps the cleaning liquid and the flushing water to fully contact the workpiece surface, further improving the flushing effect and ensuring the cleanliness of the workpiece surface.

[0018] 4. During the process from the completion of flushing to the workpiece moving up to the initial position, the normally open solenoid valve is still energized, but the water body has been completely released. At this time, the vibrating mechanism continues to work, quickly shaking off the excess water on the workpiece, avoiding the residual water on the workpiece, and facilitating the subsequent processing and machining.

[0032] As an embodiment of the present invention, it further includes a liquid flushing mechanism, which is used to improve the actual cleaning effect and prevent cleaning liquid from adhering to the workpiece after cleaning. The liquid flushing mechanism includes a piston cylinder 8 fixedly connected to the upper end of the cross plate 5.

The front side of the second piston plate 21 is elastically connected to the front inner wall of the piston cylinder 8 through a second spring 22. A round head abutting rod 23 is fixedly connected to the rear side of the second piston plate 21. The output shaft of the driving motor 7 is fixedly connected with a cam 25, and the cam 25 abuts against the round head abutting rod 23. The front space of the piston cylinder 8 communicates with a first one-way pipe 9 and a second one-way pipe 10. Check valves are installed inside both the first one-way pipe 9 and the second one-way pipe 10. The other end of the second one-way pipe 10 is communicated with an external clean water tank.

[0033] As an embodiment of the present invention, a liquid storage cylinder 16 is fixedly connected to the rear side of the connecting strip 3. A first piston plate 17 that can slide up and down is arranged inside the liquid storage cylinder 16. The lower end of the first piston plate 17 is elastically connected to the inner bottom of the liquid storage cylinder 16 through a first spring 18. The inner bottom of the liquid storage cylinder 16 communicates with the outside through a through hole. A hollow plate 12 is fixedly connected to the front side of the connecting strip 3. A plurality of liquid discharge holes 24 are opened at the inner bottom of the hollow plate 12. The other end of the first one-way pipe 9 is communicated with the inner top space of the liquid storage cylinder 16. The inner top space of the liquid storage cylinder 16 is communicated with the hollow plate 12 through a release pipe 11.

[0034] As an embodiment of the present invention, an installation column 19 is installed at the inner bottom of the liquid storage cylinder 16. A touch delay switch is installed at the upper end of the installation column 19. A normally closed solenoid valve is installed inside the release pipe 11. Further, a normally open solenoid valve is installed inside the second one-way pipe 10. Both the normally open solenoid valve and the normally closed solenoid valve are electrically connected to the touch delay switch. During specific use, when the second piston plate 21 inside the piston cylinder 8 reciprocates back and forth, water can be supplied into the liquid storage cylinder 16, and the first piston plate 17 is pushed downward to compress the first spring 18.

[0035] In the present invention, after the device is started, the ultrasonic component in the ultrasonic cleaning tank 2 starts to work, generating ultrasonic vibrations, which cooperate with the cleaning liquid to form an ultrasonic cleaning environment. The automotive drive shaft constant velocity joint to be cleaned is placed on the vibrating plate 30 in the wire mesh box 14. Each placement space is separated by a partition 15 to ensure that the workpieces are placed independently and stably. The drive motor 7 is started, and through the transmission of the reciprocating lead screw 13 and the slider 20, the wire mesh box 14 moves downward first and then upward along the chute 4, immersing the workpiece in the cleaning liquid. During the ultrasonic cleaning process, the output shaft of the drive motor 7 drives the sector-shaped conductive plate 26 to rotate. When the sector-shaped conductive plate 26 intermittently contacts the two electrical connection plates 28 simultaneously, the plate-shaped electromagnet 32 is intermittently energized, generating a magnetic force to attract the ferroalloy material under the vibrating plate 30, causing the vibrating plate 30 and the workpiece thereon to vibrate up and down. This vibration promotes the full contact between the cleaning liquid and the surface of the workpiece, improving the cleaning effect;

[0036] During the above process of moving downward and then upward, the rotation of the drive motor 7 also cooperates with the cam 25 and the round head abutting rod 23 to push the second piston plate 21 to slide back and forth in the piston cylinder 8. When the second piston plate 21 moves backward, a negative pressure is formed in the piston cylinder 8, and clear water is sucked in from the external clear water tank through the second one-way pipe 10. When the second piston plate 21 moves forward, the clear water is compressed and enters the liquid storage cylinder 16 through the first one-way pipe 9, pushing the first piston plate 17 downward and compressing the first spring 18. When the workpiece as a whole moves upward to a position higher than the liquid level of the cleaning liquid, at this time, the second piston plate 21 just moves downward to just contact the touch delay switch. At this time, both the normally open solenoid valve and the normally closed solenoid valve are energized, and the release pipe 11 is conducted. The clear water in the liquid storage cylinder 16 enters the hollow plate 12 through the release pipe 11 and sprays out from the multiple drain holes 24 at its inner bottom to wash the raised workpiece. During the flushing process, the vibrating mechanism continues to work, causing the vibrating plate 30 and the workpiece thereon to vibrate up and down. This vibration helps the cleaning liquid and the flushing water to fully contact the surface of the workpiece;

[0037] During the process from the completion of flushing to the workpiece moving up to the initial position, the normally open solenoid valve is still energized, but the water body has been completely released. Therefore, at this time, the vibrating mechanism only quickly shakes off the excess water on the workpiece to avoid residual moisture on the workpiece, facilitating subsequent processing.
