[0002] In the field of automotive engine repair and maintenance, the crankshaft, as a core component, directly affects the engine's performance and lifespan due to its cleanliness. Ultrasonic cleaning machines are widely used for crankshaft cleaning due to their high-efficiency cleaning capabilities. However, the crankshaft structure of automotive engines is complex, and oil and impurities easily remain on its surface grooves and threaded holes. Traditional cleaning machines often suffer from problems such as insecure workpiece fixation, inconvenient disassembly after cleaning, and difficult equipment maintenance, resulting in incomplete cleaning or damage to the crankshaft surface. There is an urgent need to improve cleaning efficiency and equipment practicality through structural optimization.

[0003] Existing ultrasonic cleaners for automotive engine crankshafts have significant technical defects: First, the workpiece fixing method is unreasonable. Traditional devices often use bolts for rigid fixing or simple slots, making the crankshaft prone to shaking after placement. This not only affects the ultrasonic cleaning effect but may also damage the crankshaft surface due to impact. Second, cleaning the base plate is difficult. Oil and impurities that fall off during the cleaning process easily accumulate on the base plate. Traditional base plates are mostly fixed designs, making them difficult to disassemble and clean. Long-term use can lead to bacterial growth, affect the cleaning water quality, and even cause equipment failure. In addition, the non-sealed base plate design may cause water leakage problems, affecting the safety and service life of the cleaner. Utility Model Content

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.

[0025] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an ultrasonic cleaner for automobile engine crankshafts, comprising a housing 1. Grooves are provided on both the left and right sides of the housing 1, and through holes are provided on adjacent sides of the grooves at both ends. A spring 14 is installed inside the grooves. A base plate 18 is provided on the bottom side inside the housing 1. A sealing ring 22 is fixedly connected to the top side of the base plate 18. Connecting strips 19 are provided at both the front and rear ends of the bottom side of the base plate 18. Two positioning grooves are provided on the left end of the bottom side of the housing 1, and two threaded grooves are provided on the right end of the bottom side of the housing 1. A control panel 2 is provided on the front side of the housing 1. A water outlet pipe 5 is fixedly connected to the bottom right side of the housing 1. A valve 6 is installed on the outer wall of the water outlet pipe 5. One end of the spring 14 is connected to the grooves at both ends. The two ends of the housing 1 are connected to each other on the same side, and the other end is connected to the inclined slider 7. The outer wall of the inclined slider 7 is slidably connected to the inside of the groove. The two ends of the inclined slider 7 are fixedly connected to the same side of the inclined slider 7. The outer wall of the inclined slider 13 is slidably connected to the inside of the through hole. The rear ends of the left and right sides of the housing 1 are slidably connected to the inclined slider 8. The bottom of the housing 1 is fixedly connected to the filter frame 17. The top side of the filter frame 17 is provided with a filter 15. The top side of the filter 15 is fixedly connected to the filter frame 9. The left and right sides of the filter frame 9 are provided with the limiting groove 12. The top of the left and right sides of the filter frame 9 are fixedly connected to the frame 11. The bottom side of the frame 11 abuts against the top side of the housing 1. The top side of the frame 11 is fixedly connected to the handle 10.

[0026] Specifically, when using this ultrasonic cleaner for automotive engine crankshafts, the operation process revolves around fixing the filter screen and cleaning the base plate. First, clean water is injected into the housing 1. The crankshaft to be cleaned is placed into the filter screen 15, and the two inclined slide bars 8 are pushed forward, their inclined surfaces abutting against the inclined slider 7. This causes the inclined slider 7 to slide into the groove and drive the limiting post 13 into the limiting groove 12, thereby fixing the filter screen frame 9 and the filter screen 15. During this process, the spring 14 is compressed. After cleaning, the inclined slide bars 8 are removed, and the spring 14 drives the inclined slider 7 and the limiting post 13 to reset, releasing the limitation on the filter screen frame 9. The filter screen frame 9, filter screen 15, and crankshaft can then be removed through the handle 10. Subsequently, the valve 6 is opened to drain the wastewater.

[0027] Reference Figure 1 , Figure 3 and Figure 5 The middle end of the top side of the connecting strip 19 is fixedly connected to the bottom side of the base plate 18. The left end of the top side of the connecting strip 19 is fixedly connected to the positioning strip 16. The right end of the top side of the connecting strip 19 is rotatably connected to the bolt 21. The outer wall of the positioning strip 16 is slidably connected to the inside of the positioning groove. The outer wall of the bolt 21 is threadedly connected to the inner wall of the threaded groove. The bottom side of the bolt 21 passes through the bottom side of the connecting strip 19 and is fixedly connected to the knob 20. The bottom ends of the front and rear sides of the housing 1 are fixedly connected to the mounting strip 3. The left and right ends of the bottom side of the mounting strip 3 are provided with wheels 4.

[0028] Specifically, if residual dirt on the top side of the base plate 18 affects its use after prolonged use, it needs to be cleaned and replaced. Turning the knob 20 moves the bolt 21, causing the connecting strip 19 to move the base plate 18 downwards, detaching it from the housing 1 for disassembly. During installation, first align the positioning strip 16 with the positioning groove and the bolt 21 with the threaded groove. Then, turn the knob 20 to screw the bolt 21 into the threaded groove, moving the base plate 18 upwards so that the positioning strip 16 is embedded in the positioning groove. Because the top side of the base plate 18 has a sealing ring 22, there will be no leakage. This cleaning machine, through its design of inclined slider fixing, spring return, and positioning bolt connection, achieves stable crankshaft cleaning, convenient filter fixing, and easy cleaning and replacement of the base plate.

[0029] Working Principle: In use, first, clean water is placed inside the housing 1. Then, the crankshaft of the car engine to be cleaned is placed inside the filter screen 15. The two inclined slide bars 8 are pushed forward, causing their inclined surfaces to abut against the inclined surfaces of the inclined slider 7. As the inclined slide bars 8 move forward, they push the inclined slider 7 into the groove, moving the spring 14 into the limiting groove 12. This fixes the filter screen frame 9 and the filter screen 15. Simultaneously, the movement of the inclined slider 7 compresses the spring 14. After cleaning the car engine crankshaft, moving the inclined slide bars 8 resets the spring 14, causing the inclined slider 7 and the limiting post 13 to return to their original positions, releasing the limiting effect on the filter screen frame 9. The filter screen frame 9, filter screen 15, and the internal car engine crankshaft can then be removed using the handle 10. Finally, the valve 6 is opened to drain the wastewater from the housing 1. After the device has been used for a long time, a lot of dirt may remain on the top side of the base plate 18, which will affect the normal use of the device. Therefore, the base plate 18 needs to be cleaned and replaced. First, turn the knob 20 to move the bolt 21, so that the connecting strip 19 can move the base plate 18 downward, so that the base plate 18 can be removed from the inside of the housing 1, and the base plate 18 can be disassembled for cleaning and replacement. The top side of the base plate 18 is provided with a sealing ring 22, so there will be no leakage. When installing the base plate 18, first align the positioning strip 16 with the positioning groove and align the bolt 21 with the thread groove. Then turn the knob 20 to rotate the bolt 21, so that the bolt 21 is installed into the inside of the thread groove. At the same time, the base plate 18 is moved upward, so that the positioning strip 16 enters the inside of the positioning groove, thus completing the installation of the base plate 18.

[0030] 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.
