Description

Technical Field

[0001] This utility model relates to the field of precision parts processing technology, specifically to an automated cleaning device for precision parts. Background Technology

[0002] During the machining of precision parts, oil stains often form on the surface due to processes such as cutting, stamping, and casting. Taking cutting as an example, in metal cutting, cutting fluid is typically used in large quantities to reduce friction between the tool and the workpiece and improve machining accuracy and surface quality. Cutting fluid contains various oily components, and these oily substances inevitably adhere to the surface of the parts during machining. Simultaneously, the tool's own lubricating oil may also contaminate the parts due to splashing or other reasons during prolonged cutting. Therefore, it is necessary to clean the surface of precision parts to prevent oil stains from affecting subsequent machining, which requires the use of cleaning equipment.

[0003] Traditional cleaning devices filter the cleaning solution using a static filter screen, requiring regular manual cleaning. However, this method has several drawbacks in practical use. For example, the interval between manual cleanings is difficult to control precisely. If the interval is too long, excessive accumulation of impurities on the screen not only severely hinders the normal flow of the cleaning solution and reduces filtration efficiency, but may also cause some impurities to flow back into the cleaning area with the cleaning solution due to screen blockage, re-contaminating precision parts and affecting cleaning quality. Conversely, if the interval is too short, frequent manual cleaning increases unnecessary labor costs and time, disrupts the normal cleaning process, and reduces work efficiency. Furthermore, the effectiveness of manual filter cleaning depends on the operator's experience and diligence. During the cleaning process, improper operation may cause physical damage to the screen, shortening its lifespan. Additionally, in cleaning environments with extremely high hygiene requirements, manual cleaning also carries the risk of introducing external contaminants, affecting the purity of the cleaning solution and ultimately impacting the cleaning effect on precision parts.

One end of the connecting pipe is connected and fixedly connected to one end of the filter box. A fixing plate is fixedly installed at the middle end of the fixing plate. An oblique through hole is opened in the middle of the fixing plate. One end of the connecting pipe is connected and fixedly connected to the oblique through hole. Sliding grooves are opened on both sides of the middle of the middle of the fixing plate. A filter screen is slidably engaged in the middle of the sliding groove. The area of ​​the filter screen is larger than the smaller opening of the oblique through hole. Slider blocks are fixedly installed on both sides of the middle of the middle of the filter screen. The filter screen is slidably engaged with the fixing plate through the sliders. A water pump is fixedly connected to the middle of the other end of the filter box. A return water pipe is fixedly installed in the middle of the water pump. The other end of the return water pipe is fixedly connected to the middle of the other side of the cleaning box. A fixing rod is fixedly installed at the upper end of the filter screen. A bracket is fixedly installed on one side of the upper end of the filter box. A rotating cylinder is rotatably installed in the middle of the bracket. A rotation groove is opened on the surface of the rotating cylinder. A motor is fixedly installed at the upper end of the bracket. The output end of the motor is fixedly connected to the upper end of the rotating cylinder. A support plate is fixedly installed on one side of the bracket. A cross slide plate is slidably engaged in the middle of the support plate. A connecting rod is fixedly installed at one end of the cross slide plate. The connecting rod is slidably engaged with the rotation groove. The other end of the cross slide plate is fixedly connected to the upper end of the fixing rod.

[0006] In some embodiments, springs are fixedly installed above and below the center of the cross-shaped sliding plate, and the two ends of the two springs are respectively fixedly connected to the center of the support plate above and below.

[0007] In some embodiments, a cover plate is fixedly connected to the other side of the upper middle part of the filter box by screws, and the fixing rod passes through and communicates with the middle of one end of the cover plate.

[0008] In some embodiments, multiple sets of ultrasonic output terminals are uniformly fixedly installed at the lower part of the middle of the cleaning tank, and limit blocks are fixedly installed around the upper part of the middle of the cleaning tank.

[0009] In some embodiments, the upper ends of the four limiting blocks are provided with cleaning filter frames, and each of the four corners of the upper end of the cleaning filter frame is fixedly installed with a lifting ring.

[0012] In some embodiments, valves are fixedly installed at the upper ends of both the water injection pipe and the drain pipe.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. In use, this utility model features a unique automatic filter cleaning system. A motor drives a rotating drum, and the rotating groove on the surface of the drum drives a cross slide plate to slide back and forth via a connecting rod. This causes the filter screen to reciprocate, thereby achieving self-cleaning of the filter screen's mesh. The self-cleaning function automatically shakes off impurities adhering to the filter screen during operation, effectively preventing problems such as filter screen clogging that affect the filtration effect and the circulation of cleaning fluid. It also reduces manual intervention, improves work efficiency, ensures the continuity and stability of filtration, and thus extends the service life of the filter screen.

[0015] 2. In use, this utility model employs an oblique through-hole connection between the connecting pipe and the filter box. The oblique through-hole guides the cleaning fluid to flow towards the filter screen at a specific angle. On one hand, this avoids the cleaning fluid directly impacting the filter screen vertically, preventing excessive local pressure and allowing the cleaning fluid to be more evenly dispersed on the filter screen, thus improving filtration efficiency. On the other hand, the scouring effect generated by the oblique through-hole reduces the accumulation of impurities at the connection between the connecting pipe and the filter box, ensuring smooth operation of the cleaning fluid circulation system and optimizing the flow of the cleaning fluid throughout the entire device.

[0016] 3. In use, the springs installed above and below the center of the cross-shaped sliding plate provide cushioning and stability. The spring structure effectively reduces impact, wear, and noise, making the movement of the cross-shaped sliding plate smoother and ensuring the accuracy and reliability of the filter's reciprocating motion, thereby further improving the stability of the entire cleaning and filtration process.

[0023] 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.

[0024] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: an automated cleaning device for precision parts, including a cleaning box 1 and a filter box 2. The filter box 2 is fixedly connected to one end of the cleaning box 1. A connecting pipe 21 is fixedly connected to the middle of one side of the cleaning box 1. One end of the connecting pipe 21 is connected to one end of the filter box 2. A fixing plate 22 is fixedly installed at the middle end of the filter box 1. An oblique through hole 23 is opened in the middle of the fixing plate 22. One end of the connecting pipe 21 is connected to the oblique through hole 23. Sliding grooves 24 are opened on both sides of the middle of one end of the fixing plate 22. A filter screen 25 is slidably engaged in the middle of the sliding groove 24. The area of ​​the filter screen 25 is larger than the smaller opening of the oblique through hole 23. Sliding blocks 26 are fixedly installed on both sides of the middle of one end of the filter screen 25. The filter screen 25 is slidably engaged with the fixing plate 22 through the sliding blocks 26. The other side of the filter box 2... A water pump 36 is fixedly connected to the middle of the end of the filter box 2. A return water pipe 37 is fixedly installed in the middle of the water pump 36. The other end of the return water pipe 37 is fixedly connected to the middle of the other side of the cleaning box 1. A fixing rod 35 is fixedly installed on the upper end of the filter screen 25. A bracket 27 is fixedly installed on one side of the upper end of the filter box 2. A rotating drum 28 is rotatably installed in the middle of the bracket 27. A rotary groove 29 is opened on the surface of the rotating drum 28. A motor 30 is fixedly installed on the upper end of the bracket 27. The output end of the motor 30 is fixedly connected to the upper end of the rotating drum 28. A support plate 31 is fixedly installed on one side of the bracket 27. A cross slide plate 32 is slidably engaged in the middle of the support plate 31. A connecting rod 34 is fixedly installed on one end of the cross slide plate 32. The connecting rod 34 is slidably engaged with the rotary groove 29. The other end of the cross slide plate 32 is fixedly connected to the upper end of the fixing rod 35.

[0025] In this embodiment, the cleaning fluid circulates between the cleaning tank 1 and the filter tank 2 through components such as the connecting pipe 21, the filter box 2, the water pump 36, and the return water pipe 37. The inclined angle of the oblique through-hole 23 allows the cleaning fluid flowing from the connecting pipe 21 into the filter box 2 to flow in a specific direction, enabling it to more evenly impact the filter screen 25. This avoids the cleaning fluid directly impacting the filter screen 25 vertically, preventing excessive local pressure and thus improving the filtration efficiency and service life of the filter screen 25. The filter screen 25 filters impurities in the cleaning fluid, ensuring its cleanliness, thereby improving the cleaning effect, extending the service life of the cleaning fluid, and reducing costs. The motor 30 drives the rotating drum 28 to rotate. The rotating groove 29 on the surface of the rotating drum 28 drives the cross slide plate 32 to reciprocate on the support plate 31 via the connecting rod 34, which in turn drives the fixed rod 35 and the filter screen 25 to reciprocate. This effectively prevents impurities from clogging the filter screen. When the filter screen 25 reciprocates, impurities attached to it are removed by the filter screen. The shaking and trembling make it easier for impurities to fall off, preventing them from accumulating on the filter screen and causing blockages. This ensures the filtration effect and flow rate of the cleaning fluid, allowing it to maintain good cleanliness. This is beneficial for improving the cleaning quality of precision parts and extending the service life of the filter screen 25. The timely removal of impurities reduces the pressure and corrosion on the filter screen, lowering the risk of filter screen breakage and extending its service life, thereby reducing the maintenance cost of the device. At the same time, it enhances the filtration effect. The reciprocating motion of the filter screen 25 allows for more thorough interception and filtration of impurities in the cleaning fluid. The reciprocating motion of the filter screen causes disturbance in the cleaning fluid near the screen, giving impurities in different locations more opportunities to be captured, improving the comprehensiveness and thoroughness of filtration. The motor 30 drives the rotating drum 28 to rotate and the water pump 36 circulates the cleaning fluid, making the entire device highly automated, reducing manual labor, lowering labor intensity, and improving the stability and consistency of cleaning and filtration.

[0026] Example 2: Figure 1-4 As shown, springs 33 are fixedly installed on the upper and lower sides of the cross slide plate 32. The two ends of the two springs 33 are fixedly connected to the upper and lower sides of the support plate 31, respectively. A cover plate 20 is fixedly connected to the other side of the upper middle part of the filter box 2 by screws. A fixing rod 35 passes through and connects to the middle of one end of the cover plate 20. Multiple ultrasonic output terminals 17 are evenly fixedly installed on the lower part of the middle of the cleaning box 1. Limiting blocks 14 are fixedly installed on all four sides of the upper part of the middle of the cleaning box 1. A cleaning filter frame 15 is provided on the upper end of the four limiting blocks 14. A hanging ring 16 is fixedly installed on the four corners of the upper end of the cleaning filter frame 15. The cleaning filter frame 15 is slidably snapped into the middle of the cleaning box 1. A water injection pipe 11 is fixedly connected to one side of the middle of the other end of the cleaning box 1. A drain pipe 12 is fixedly connected to the other side of the middle of the other end of the cleaning box 1. A valve 13 is fixedly installed on the upper end of both the water injection pipe 11 and the drain pipe 12.

[0027] In this embodiment, the springs 33 installed above and below the middle of the cross slide plate 32 act as a buffer when the cross slide plate 32 reciprocates, effectively reducing the impact force between the cross slide plate 32 and the support plate 31, reducing wear and noise caused by collisions, and extending the service life of the cross slide plate 32 and the support plate 31. They also reduce the impact of vibrations generated during device operation on other components. The cover plate 20 on the other side of the upper middle of the filter box 2 is installed with screws, facilitating disassembly and installation. When it is necessary to inspect, maintain, or replace components inside the filter box 2, such as the filter screen 25 and connecting rod 34, the cover plate 20 can be easily opened, thereby improving the maintainability of the device. Multiple sets of ultrasonic output terminals 17 are evenly fixedly installed below the middle of the cleaning tank 1, which can generate ultrasonic vibrations. The cavitation effect generated when the ultrasonic waves propagate in the cleaning fluid can generate a large number of tiny bubbles in the cleaning fluid. When these bubbles burst instantaneously, they produce… The powerful impact force allows it to penetrate deep into the tiny gaps and holes of precision parts, peeling away dirt and impurities from the surface of the parts, greatly improving cleaning efficiency and quality. It is especially suitable for cleaning precision parts with complex shapes and high precision requirements, achieving comprehensive cleaning of precision parts and avoiding cleaning dead corners. The limiting blocks 14 fixedly installed around the upper part of the middle of the cleaning tank 1 can position and limit the cleaning filter frame 15, ensuring that the cleaning filter frame 15 is accurately placed in the middle of the cleaning tank 1, preventing it from shaking or shifting during the cleaning process, and ensuring the stability and reliability of the cleaning process. The lifting rings 16 fixedly installed at the four corners of the upper end of the cleaning filter frame 15 make it convenient to use lifting equipment to put the cleaning filter frame 15 into or take it out of the cleaning tank 1. The water injection pipe 11 and drain pipe 12 connected to the other end of the cleaning tank 1, as well as the valve 13 installed at the upper end, allow the operator to flexibly control the injection and discharge of cleaning fluid as needed.

[0028] like Figure 1-5As shown, during use, first open valve 13 on water inlet pipe 11 to introduce cleaning solution into cleaning tank 1. Once the cleaning solution reaches the appropriate level, close valve 13, place the precision parts to be cleaned into cleaning filter frame 15, and use lifting ring 16 to hoist them above the limiting block 14 inside cleaning tank 1. Then, activate multiple ultrasonic output terminals 17 in the lower middle part of cleaning tank 1. The ultrasonic output terminals 17 generate ultrasonic vibrations, creating a cavitation effect in the cleaning solution. The numerous tiny bubbles generated by the cavitation effect burst instantaneously, generating a powerful impact force that penetrates deep into the tiny gaps and holes of the precision parts, peeling away dirt and impurities from the surface of the parts, thus cleaning the precision parts. Under the action of water pump 36, the cleaning solution flows into filter tank 2 through connecting pipe 21. When the cleaning solution passes through the oblique through-hole 23 on fixed plate 22, the oblique through-hole 23 guides the cleaning solution to flow at a specific angle towards filter screen 25, uniformly impacting the filter screen 25. Simultaneously, the flushing effect of the oblique through-hole 23 reduces the accumulation of impurities at the connection between connecting pipe 21 and filter tank 2. Impurities in the cleaning fluid are intercepted by the filter screen 25. The filtered cleaning fluid continues to flow to the other end of the filter box 2, and then the motor 30 is started to drive the rotating drum 28 to rotate. The rotary groove 29 on the surface of the rotating drum 28 drives the cross slide plate 32 to slide back and forth on the support plate 31 through the connecting rod 34. The reciprocating motion of the cross slide plate 32 is transmitted to the filter screen 25 through the fixed rod 35, causing the filter screen 25 to reciprocate within the sliding groove 24. This reciprocating motion can prevent impurities from clogging the filter screen, improve the filtration effect and service life of the filter screen, and also enhance the interception and filtration capacity of impurities in the cleaning fluid. The springs 33 above and below the middle of the cross slide plate 32 play a buffering and stabilizing role during the movement of the cross slide plate 32. Spring 33 reduces the impact force between the cross slide plate 32 and the support plate 31, reducing wear and noise, while making the movement of the cross slide plate 32 more stable, ensuring the stability and reliability of the reciprocating motion of the filter screen 25. The filtered cleaning liquid is drawn by the water pump 36 at the other end of the filter box 2 and sent back to the cleaning box 1 through the return water pipe 37, realizing the recycling of the cleaning liquid and thus extending the service life of the cleaning liquid. After cleaning, the ultrasonic output end 17 and the motor 30 are turned off, the valve 13 on the drain pipe 12 is opened to drain the cleaning liquid, and then the cleaning filter frame 15 is taken out of the cleaning box 1 through the lifting ring 16. Finally, the filter screen 25 and other components in the filter box 2 can be inspected and maintained as needed by disassembling the cover plate 20.
