[0002] An assembled crankshaft is composed of multiple parts, including the left half-shaft, right half-shaft, crank pin, and connecting rod, all press-fitted together. A composite camshaft is composed of parts such as the cam and camshaft, all press-fitted together. Some motorcycle engines are assembled from parts such as assembled crankshafts and composite camshafts. Before press-fitting, the parts of assembled crankshafts and composite camshafts need to be cleaned and dried to ensure cleanliness, thereby guaranteeing press-fitting quality and preventing impurities from affecting press-fitting accuracy.

[0003] Currently, the cleaning methods for assembled crankshaft components and camshafts can be carried out using most industrial cleaning machines, such as spray cleaners, ultrasonic cleaners, and surge cleaners. However, existing cleaning machines do not have drying functions, requiring other measures for drying, such as manual drying with a handheld air gun. Utility Model Content

A multi-station rotary table cleaning machine includes a frame 1, tool clamps 2, a rotating device 3, a feeding device 4, a cleaning device 5, an air blowing device 6, a drying device 7, and a discharging device 8. Five stations are equally spaced on the frame 1, arranged in a circle. The five stations are a feeding station, a cleaning station, an air blowing station, a drying station, and a discharging station. Five tool clamps 2 are provided, each equipped with a clamping assembly for holding different parts. The rotating device 3 is mounted on the frame 1 and connects to the five tool clamps. 2.

[0069] Please refer to the following: Figure 15 , Figure 15This is a schematic diagram of the air blowing box in the multi-station rotary table cleaning machine of this utility model. In one embodiment, the air blowing device 6 includes an air blowing box 61, an air inlet pipe, and an air blowing lifting assembly 62. The bottom of the air blowing box 61 is open, and multiple air blowing nozzles 63 are provided at the top inside the air blowing box 61. The air inlet pipe is connected to the multiple air blowing nozzles for connecting to an air source. The air blowing lifting assembly 62 is connected to the air blowing box 61 for driving the air blowing box 61 to rise and fall. When the cleaned parts move to the air blowing station, the air blowing lifting assembly 62 drives the air blowing box 61 to fall, so that the air blowing box 61 contacts the rotary table 31 and is fitted onto the outside of the tool clamp 2 located at the air blowing station, sealing the air blowing station to prevent water splashing during the air blowing process and reduce the environmental noise of the air blowing process. The air inlet pipe includes an air source that can provide compressed air as power. The air source can be an existing air compressor on the market. Compressed air is then supplied through the air inlet pipe, and high-pressure airflow is blown out through the air nozzle 63 to initially dry the cleaned parts, blowing away some water droplets. The air nozzle 63 uses the same fan-shaped nozzle as the cleaning nozzle 55, achieving high-pressure blowing while saving airflow. Multiple air nozzles 63 are located at the top of the air blowing box 61. The air nozzles 63 can be arranged according to the shape and arrangement of the parts, so that each part has several corresponding air nozzles 63 for blowing, ensuring that each position of each part is blown in place. After blowing is completed, the air blowing lifting assembly 62 drives the air blowing box 61 to rise, so that the air blowing box 61 is no longer in contact with the turntable 31, and the rising height of the air blowing box 61 should not affect the rotation of the tool clamp 2.

[0070] To ensure a more thorough cleaning of all components, in one embodiment, the right half-shaft clamp assembly 22 further includes a nozzle holder 223. The nozzle holder 223 is located on the side of the second fixed support 221 away from the second movable support 222 and is mounted on the tool clamp 2.

The structure of 53 is the same. The air nozzle 63 is connected to the fourth conveying channel of the air blowing box 61, and the air inlet pipe is connected to the fourth inlet of the air blowing box 61. The tool clamp 2 is provided with a third through hole connected to the first inlet, a fourth through hole connected to the second inlet, a fifth through hole connected to the third inlet, and a sixth through hole 220 for connecting to the conveying pipe 534. The tool clamp 2 is provided with a fifth conveying channel 28, which is connected to the third through hole, the fourth through hole, the fifth through hole and the sixth channel 220 respectively. During the cleaning process, when the cleaning box 53 descends to contact the tool clamp 2, the conveying pipe 534 inside the cleaning box 53 connects to the sixth through hole 220 of the tool clamp 2 located within the cleaning process. At this time, the water pump 52 is turned on, and the water pump 52 conveys water to the fourth conveying channel 532 through the water supply pipe. The fourth conveying channel 532 then conveys water to each cleaning nozzle 55, and the water in the fourth conveying channel 532 is conveyed to the fifth conveying channel 28 through the conveying pipe 534. The fifth conveying channel 28 then conveys water to the first conveying channel 2231, the second conveying channel 2311, and the third conveying channel 2511, respectively. The centerline of the crankshaft nozzle 224 is slightly higher than the centerline of the right half-shaft, and the nozzle orifice of the crankshaft nozzle 224 is aligned with the keyway on the right half-shaft for cleaning the keyway and the oil hole at the top of the right half-shaft. The first outlet 2312 on the third fixed bracket 231 is aligned with the inside of the crank pin for cleaning the inside of the crank pin.The second outlet 2512 of the front bracket 251 is aligned with the front end of the camshaft for cleaning the front end of the camshaft, thereby avoiding cleaning dead spots in various parts and making the cleaning of each part more thorough. During the air blowing process, when the air blowing box 61 descends to contact the tool clamp 2, the delivery pipe 534 inside the air blowing box 61 connects with the sixth through hole 220 on the tool clamp 2 located in the air blowing process. The subsequent gas delivery process is the same as the water delivery process in the cleaning process, and will not be described again here.

[0071] Please refer to the following: Figure 17 , Figure 17 This is a schematic diagram of the water return device in the multi-station rotary table cleaning machine of this utility model. In one embodiment, the multi-station rotary table cleaning machine of this utility model further includes a water return device 9. A first through hole 26 is provided on the tool clamp 2, and a water collection connector 29 communicating with the first through hole 26 is provided at the bottom of the tool clamp 2. A second through hole for the water collection connector 29 to pass through is provided on the rotary table 31. The water return device 9 includes a first water return pipe 91 and a second water return pipe 92. The first water return pipe 91 is located directly below the water collection connector 29 located at the cleaning station, and the second water return pipe 92 is located directly below the water collection connector 29 located at the air blowing station. The diameters of the first return water pipe 91 and the second return water pipe 92 are larger than the diameter of the water collection connector 29. The distances between the first return water pipe 91 and the second return water pipe 92 and the corresponding water collection connector 29 are small. Water generated in the cleaning and blowing processes flows into the water collection connector 29 through the first through hole 26 on the tool clamp 2 and the second through hole on the turntable 31. After being collected by the water collection connector 29, it flows into the first return water pipe 91 or the second return water pipe 92 and is discharged through the first return water pipe 91 or the second return water pipe 92. In one embodiment, a water receiving tray 93 is sleeved on the outer side of the first return water pipe 91 and the second return water pipe 92. The water receiving tray 93 is to prevent water droplets from splashing from the cleaning and blowing stations when the turntable 31 rotates.

[0072] Please refer to the following: Figure 16 , Figure 16This is a schematic diagram of the drying box in the multi-station rotary table cleaning machine of this utility model. In one embodiment, the drying device 7 includes a drying box 71, a drying lifting assembly 72, a vacuum suction cup 73, a vacuum pump, and a vacuum lifting assembly 74. A heating assembly 75 is provided at the top of the box. The drying lifting assembly 72 is connected to the drying box 71 and is used to drive the drying box 71 to rise and fall. The vacuum suction cup 73 is located directly below the water collection connector 29 at the drying station. An air extraction hole is opened on the side wall of the vacuum suction cup 73. The vacuum pump is connected to the air extraction hole. The vacuum lifting assembly 74 is connected to the vacuum suction cup 73 and is used to drive the vacuum suction cup 73 to rise and fall, so that the vacuum suction cup 73 abuts or separates from the rotary table 31. When the parts after the air blowing process move to the drying station, the drying lifting assembly 72 drives the drying box 71 to fall, so that the drying box 71 contacts the rotary table 31 and is fitted onto the outside of the tool clamp 2 located at the drying station to seal the drying station. Then, the vacuum lifting assembly 74 drives the vacuum suction cup 73 to rise, causing it to contact the turntable 31. At this time, the vacuum suction cup 73 is fitted onto the outside of the water collection connector 29 located at the drying station. The vacuum pump is started to evacuate the inside of the drying box 71, creating a negative pressure environment inside the drying box 71. This lowers the boiling point of the cleaning liquid. Simultaneously, the heating assembly 75 is activated to heat the inside of the drying box 71, evaporating the liquid on the surface of the parts, thereby achieving the drying purpose. After drying, the drying lifting assembly 72 drives the drying box 71 to rise, causing it to detach from the turntable 31. The rising height of the drying box 71 should not affect the rotation of the tool clamp 2. The vacuum lifting assembly 74 then drives the vacuum suction cup 73 to descend, separating the vacuum suction cup 73 from the turntable 31. The descending height of the vacuum suction cup 73 should not affect the rotation of the turntable 31. Furthermore, the cleaning lifting assembly 54, the air blowing lifting assembly 62, and the drying lifting assembly 72 can adopt commonly used existing lifting devices, such as motor and ball screw structures or telescopic cylinders, which will not be elaborated here.

[0073] In one embodiment, the cleaning box 53, the air blowing box 61, and the drying box 71 have the same structure. A pressure-sealing ring 27 is provided on the tool clamping plate 2, and a rubber ring 210 is provided between the pressure-sealing ring 27 and the tool clamping plate 2. The internal dimensions of the pressure-sealing ring 27 are larger than the external dimensions of the cleaning box 53, while the internal dimensions of the rubber ring 210 are smaller than the internal dimensions of the cleaning box 53. Several clamping components are located within the rubber ring 210. The pressure-sealing ring 27 is used to fix the rubber ring to the tool clamping plate 2. The cleaning box 53, the air blowing box 61, or the drying box 71 descends to contact the rubber ring 210 on the tool clamping plate 2. The function of the rubber ring is to prevent water or air leakage at the workstation during processing, ensuring the sealing effect of the process. In one embodiment, baffles are provided on both sides of the tool clamping plate 2 in the radial direction of the turntable 31. The baffles further ensure the sealing effect of the process. In one embodiment, grooves for placing the rubber ring 210 are provided on the tool clamping plate 2.
