[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0027] In this technical solution, a cleaning and drying device for a crankshaft includes a bottom plate 1, an ultrasonic cleaning box body 2, and a dryer 3. The ultrasonic cleaning box body 2 is fixedly installed at the upper end of the bottom plate 1, and the dryer 3 is fixedly installed on one side of the ultrasonic cleaning box body 2. An adjusting and lifting structure is provided at the rear wall surface of the ultrasonic cleaning box body 2. The adjusting and lifting structure includes an adjusting frame 4, two lifting auxiliary rods 5, a first motor 6, a first lead screw 7, a moving block 8, and an installation vertical plate 9;

[0028] The adjustment frame 4 is fixedly installed at the rear wall surface of the ultrasonic cleaning box body 2. Two lifting auxiliary rods 5 are respectively installed on both sides inside the adjustment frame 4. The first motor 6 is fixedly installed at the lower end of the rear wall surface of the ultrasonic cleaning box body 2. One end of the first lead screw 7 is connected to the driving end of the first motor 6, and the other end is movably installed at one side of the upper end of the adjustment frame 4 through a bearing. Both ends of the moving block 8 are movably sleeved on the upper ends of the two lifting auxiliary rods 5, and the rear wall surface is movably connected to the first lead screw 7. The installation vertical plate 9 is fixedly installed at the front wall surface of the moving block 8.

[0029] In this technical solution, the ultrasonic cleaning box body 2 is provided to store the cleaning liquid. When cleaning the crankshaft, the first motor 6 drives the first lead screw 7 to rotate, changing the height of the moving block 8 on the first lead screw 7 and the upper ends of the two lifting auxiliary rods 5. Lowering the moving block 8 and the installation vertical plate 9 to the lowest end can completely lower the crankshaft into the ultrasonic cleaning box body 2. By energizing the ultrasonic cleaning box body 2 to work, the crankshaft can be cleaned.

[0030] In some technical solutions, refer to Figure 1 , an adjustment clamping structure is provided at the front end of the installation vertical plate 9. The adjustment clamping structure includes two fixed plates 10, a double-headed motor 11, a guide rod 12, two second lead screws 13, and two moving installation blocks 14;

[0031] The two fixed plates 10 are respectively installed on both sides at the front end of the installation vertical plate 9. The double-headed motor 11 is fixedly installed at the lower side at the front end of the installation vertical plate 9. Both ends of the guide rod 12 are connected to the two fixed plates 10 respectively. One end of each of the two second lead screws 13 is connected to the driving ends on both sides of the double-headed motor 11 respectively, and the other ends are respectively movably embedded in the two fixed plates 10. The two moving installation blocks 14 are respectively movably sleeved on both sides of the upper ends of the two second lead screws 13 and the guide rod 12.

[0032] In this technical solution, when cleaning crankshafts of different specifications, the double-headed motor 11 provided at the center of the front end of the installation vertical plate 9 works to synchronously drive the two second lead screws 13 to rotate in the two fixed plates 10. Under the meshing action of the second lead screws 13 and the moving installation blocks 14, the two moving installation blocks 14 move relatively, thus changing the overall distance between the two moving installation blocks 14 to meet the installation requirements for cleaning crankshafts of different specifications.

[0033] In some technical solutions, refer to Figure 1 , a moving support structure is provided at the front ends of the two moving installation blocks 14. The moving support structure includes two connecting frames 15 and two support blocks 16;

[0034] The two connecting frames 15 are respectively installed at the front ends of the two moving installation blocks 14. The two support blocks 16 are respectively fixedly installed at one side of the lower ends of the two connecting frames 15.

[0035] In this technical solution, two connecting brackets 15 are connected to two movable mounting blocks 14, and the two support blocks 16 at the bottom support the two ends of the crankshaft respectively.

[0037] One end of the connecting pipe 17 is connected to the air outlet end of the dryer 3, and the two drying covers 18 are respectively fixedly installed at the upper ends of the two side walls inside the ultrasonic cleaning box body 2 and are both connected to the connecting pipe 17.

[0038] In this technical solution, after the crankshaft cleaning is completed, the crankshaft is lifted by the rotation of the first motor 6. Subsequently, the dryer 3 on one side of the ultrasonic cleaning box body 2 works, and the hot air is respectively conveyed into the two drying covers 18 through the connecting pipe 17, and the crankshaft is dried by blowing through the two drying covers 18.

[0039] In some technical solutions, refer to Figure 1 , a support groove 19 is opened at the upper end of the support block 16, and the two movable mounting blocks 14 are both movably sleeved on the upper ends of the two second lead screws 13 through internal threads, and the moving block 8 is movably sleeved on the upper end of the first lead screw 7 through internal threads.

[0040] Working principle: When cleaning crankshafts of different specifications, the double-headed motor 11 arranged at the center of the front end of the installation vertical plate 9 works to synchronously drive the two second lead screws 13 to rotate in the two fixing plates 10. Under the meshing action of the second lead screw 13 and the movable mounting block 14, the two movable mounting blocks 14 move relatively, so as to change the overall distance between the two movable mounting blocks 14, and thus meet the cleaning and installation requirements of crankshafts of different specifications. The two connecting brackets 15 are connected to the two movable mounting blocks 14, and the two support blocks 16 at the bottom support the two ends of the crankshaft respectively, realizing the cleaning and installation operation of the crankshaft. During cleaning, the ultrasonic cleaning box body 2 is used to store the cleaning liquid. When cleaning the crankshaft, the first motor 6 drives the first lead screw 7 to rotate, changing the height of the moving block 8 on the first lead screw 7 and the upper ends of the two lifting auxiliary rods 5, and lowering the moving block 8 and the installation vertical plate 9 to the lowest end, so that the crankshaft can be completely lowered into the ultrasonic cleaning box body 2. The ultrasonic cleaning box body 2 is powered on to work to clean the crankshaft. After the crankshaft cleaning is completed, the crankshaft is lifted by the rotation of the first motor 6. Subsequently, the dryer 3 on one side of the ultrasonic cleaning box body 2 works, and the hot air is respectively conveyed into the two drying covers 18 through the connecting pipe 17, and the crankshaft is dried by blowing through the two drying covers 18.
