[0014] Embodiment 1:

[0015] Such as Figure 1 - Figure 2As shown in the figure, the present utility model discloses an outer side cleaning device for an annular die-casting part, including a box body 1. A partition plate 4 is arranged inside the box body 1, dividing the box body 1 into upper and lower parts to prevent water from flowing onto the motor 5 during cleaning and causing damage to the motor 5. On one side of the box body 1 above the partition plate 4, there is an operation window 2, and the operation window 2 is provided with a movable door 3 to prevent water from splashing outside the box body 1 during cleaning. Vertically arranged on the inner wall of the box body 1 below the partition plate 4 is a motor 5. The output shaft of the motor 5 passes through the partition plate 4, and the output shaft of the motor 5 is in sealed rotational connection with the partition plate 4. At the top end of the output shaft of the motor 5 in the axial direction, there is a turntable 6. In the axial direction at the center of the turntable 6, there is a limit post 8, and an annular die-casting part 7 is arranged on the limit post 8. The outer diameter of the turntable 6 is smaller than the outer diameter of the annular die-casting part 7 and larger than the inner diameter of the annular die-casting part 7. The outer diameter of the limit post 8 is equal to the inner diameter of the annular die-casting part 7. The limit post 8 restricts the displacement of the annular die-casting part 7 in the horizontal direction, and at the same time, the turntable 6 drives the annular die-casting part 7 to rotate. On the inner wall of the box body 1 on the side of the annular die-casting part 7 away from the movable door 3, there is a brush 16, and the brush 16 abuts against the outer side of the annular die-casting part 7. When the turntable 6 drives the annular die-casting part 7 to rotate, the brush 16 brushes the outer side of the annular die-casting part 7. Oppositely arranged on the inner walls of the box body 1 on both sides of the annular die-casting part 7 are first spray heads 11. The first spray heads 11 rinse the outer side of the annular die-casting part 7, cleaning the outer side of the annular die-casting part 7 and at the same time cooling the annular die-casting part 7 to prevent damage to the brush 16 or the annular die-casting part 7 caused by high temperature generated by the friction between the brush 16 and the annular die-casting part 7. On one side of the box body 1, there is a water tank 9. The water tank 9 and the first spray heads 11 are connected through a first pipeline 10. One end of the first pipeline 10 extends from the upper side of the water tank 9 to the bottom side of the water tank 9, and a water pump 12 is arranged on the first pipeline 10. The water pump 12 pumps out the water in the water tank 9 for pressurization so that the water flows out from the first spray heads 11. The partition plate 4 is inclined towards the water tank 9. On the side wall of the box body 1 at the inclined end of the partition plate 4 towards the water tank 9, there is a drain port 17, and the drain port 17 is communicated with the water tank 9. Vertically arranged near the drain port 17 of the water tank 9 is a filter screen 24. The inclined partition plate 4 guides the cleaned water into the water tank 9 through the drain port 17. After the cleaned water is filtered by the filter screen 24, it can be sprayed again, saving water. Of course, the end of the first pipeline 10 is located in the water tank 9 on the side of the filter screen 24 away from the drain port 17.

[0016] A cylinder 13 is vertically downwardly provided on the upper side of the box body 1. A pressing plate 14 is vertically downwardly provided at the telescopic end of the cylinder 13. The pressing plate 14 is rotatably connected to the telescopic end of the cylinder 13. The pressing plate 14 is correspondingly arranged with the annular die casting 7. The outer diameter of the pressing plate 14 is larger than the inner diameter of the annular die casting 7. A limiting hole 81 is axially provided at the top end of the limiting column 8. A limiting rod 15 corresponding to the limiting hole 81 is vertically provided at the bottom end of the pressing plate 14 to limit the displacement of the pressing plate 14 in the horizontal direction; during cleaning, the cylinder 13 pushes the pressing plate 14 to make its bottom end fit with the upper surface of the annular die casting 7, and the limiting rod 15 is inserted into the limiting hole 81 to limit the displacement of the annular die casting 7 in the vertical direction, so as to fix the annular die casting 7 on the turntable 6 by means of the pressing plate 14, ensuring that the annular die casting 7 can be driven to rotate synchronously when the turntable 6 rotates, so as to maintain the stability of the cleaning effect.

[0017] A second spray head 26 is vertically downwardly provided on the box body 1 above the brush 16. A second pipeline 25 is provided at the input end of the second spray head 26. The second pipeline 25 is connected to the first pipeline 10. A flow valve 28 is arranged on the second pipeline 25. The second spray head 26 sprays and cleans the brush 16. In order to prevent the water pressure sprayed by the second spray head 26 from being too large and causing the brush 16 to bend downward and unable to contact the annular die casting 7, the flow valve 28 is used to control the spraying pressure of the second spray head 26 to ensure that the brush 16 is rinsed without affecting the position of the brush 16.

[0018] The lower side of the movable door 3 is hingedly connected to the lower side of the operation window 2. When the movable door 3 is opened, the movable door 3 can maintain the open and closed state by its own weight, ensuring the safety of personnel when replacing the annular die casting 7. The upper side of the movable door 3 and the upper side of the operation window 2 are magnetically connected for easy opening and closing.

[0019] A number of hydraulic cylinders 27 are vertically upwardly provided at the bottom side of the box body 1. The number of the hydraulic cylinders 27 is four, and the four hydraulic cylinders 27 move synchronously. The hydraulic cylinders 27 are annularly distributed with the motor 5 as the center. The telescopic ends of the hydraulic cylinders 27 pass through the partition plate 4 and correspond to the part of the annular die casting 7 outside the turntable 6; after the annular die casting 7 is cleaned, the hydraulic cylinders 27 can lift the annular die casting 7 for easy removal of the annular die casting 7.

[0020] On the side wall of the water tank 9 near the drainage port 17 of the filter net 24, a high-level liquid sensor 22 is provided, and the high-level liquid sensor 22 is lower than the drainage port 17; on the side wall of the water tank 9 on the side of the filter net 24 away from the drainage port 17, a low-level liquid sensor 23 is provided, and the low-level liquid sensor 23 is higher than the nozzle of the first pipeline 10; on the bottom side of the water tank 9 on the side of the filter net 24 near the drainage buckle 17, a drain pipe 18 is provided, and a first electromagnetic valve 19 is provided on the drain pipe 18. At the top of the water tank 9 on the side of the filter net 24 away from the drainage port 17, a water replenishing pipe 20 is provided, and the water replenishing pipe 20 can be connected to a water source. A second electromagnetic valve 21 is provided on the water replenishing pipe 20. The first electromagnetic valve 19, the second electromagnetic valve 21, the low-level liquid sensor 23, and the high-level liquid sensor 22 can be electrically connected to a controller; when the liquid level in the water tank 9 is higher than the high-level liquid sensor 22, the high-level liquid sensor 22 sends a signal, and the controller controls the first electromagnetic valve 19 to open, and the liquid in the water tank 9 is discharged from the drain pipe 18, and impurities can be removed at the same time. When the liquid level is lower than the high-level liquid sensor 22, the first electromagnetic valve 19 is closed to make the liquid level lower than the drainage port 17 to prevent the waste water from flowing back into the box body 1; when the liquid level is lower than the low-level liquid sensor 23, the second electromagnetic valve 21 is opened, and the water replenishing pipe 20 replenishes the water in the water tank 9. When the liquid level reaches the high-level electromagnetic valve 19, the second electromagnetic valve 21 is closed to ensure the normal spraying of the first spray head 11 and the second spray head 26. The above operations can control the liquid level in the water tank 9 between the high-level liquid sensor 22 and the low-level liquid sensor 23, automatically drain and replenish water, with a high degree of automation and high stability.
