Description

Technical Field

[0001] This utility model relates to the field of crankshaft processing technology, and more specifically, to an integrated crankshaft cleaning and drying device. Background Technology

[0002] The crankshaft is a crucial component of an engine. It bears the force transmitted from the connecting rod and converts it into torque, which is then output through the crankshaft to drive other accessories on the engine. The crankshaft requires sufficient strength and rigidity, as well as good balance during rotation. Therefore, the manufacturing precision of the crankshaft is very high. Currently, after the crankshaft is manufactured, it needs to undergo a cleaning process to remove contaminants from the surface and oil passages to ensure safe use in subsequent applications.

[0003] The announcement number CN212120991U proposed an integrated crankshaft cleaning and drying device, which solves the problems of high labor intensity and blind spots in manual cleaning; however, single high-pressure spray cleaning cannot guarantee the cleaning effect on oil stains in the crankshaft oil passage holes, so the cleaning process needs to be improved.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0033] like Figures 1 to 3 As shown, a crankshaft cleaning and drying integrated device includes a cleaning tank 1, an ultrasonic transducer 2, a rotating table 3, a placement trough, a telescopic cylinder 4, a cover plate 5, a connecting roller 6, a chuck 7, a drive assembly, a circumferential high-pressure spray assembly, and a sludge pump 8.

[0034] The ultrasonic transducer 2 is fixed inside the cleaning tank 1;

[0035] The rotating table 3 is rotatably set at the bottom of the cleaning tank 1, and the rotating table 3 is provided with a placement groove that matches one end of the crankshaft (the placement groove is not shown in the figure, but specifically matches the shape of the end face of the crankshaft away from the chuck).

[0036] Telescopic cylinders 4 are symmetrically fixed on the cleaning tank 1, and the telescopic cylinders 4 are connected to a cover plate 5 that cooperates with the cleaning tank 1.

[0037] One end of the connecting roller 6 is connected to the chuck 7 and the connecting roller 6 is rotatably connected to the cover plate 5; the other end of the connecting roller 6 is connected to the drive assembly.

[0038] The liftable circumferential high-pressure spray assembly is located on the outside of the crankshaft;

[0039] The sludge pump 8 is fixed on the cleaning tank 1 and connected to the bottom of the cleaning tank 1.

[0040] To increase the number of crankshafts cleaned in a single operation, further optimizations to the above solution are needed, such as... Figure 1 As shown, the bottom of the cleaning tank 1 is rotatably connected to three equally spaced rotating platforms 3 via bearings. The connecting rollers 6 correspond one-to-one with the rotating platforms 3, and the two ends of the connecting rollers 6 are respectively connected to the drive components and the chuck 7 located directly above the rotating platforms 3.

[0041] Specific implementation of the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the drive assembly includes a mounting plate 9, a main gear 10, a secondary gear 11, and a servo motor 12.

[0042] Mounting plate 9 is fixed on connecting roller 6 located in the middle;

[0043] The main gear 10 is fixed on the mounting plate 9;

[0044] Two auxiliary gears 11 are fixed on the connecting rollers 6 on both sides, and the auxiliary gears 11 mesh with the main gear 10;

[0045] The servo motor 12 is fixed on the cover plate 5, and the motor shaft of the servo motor 12 is fixedly connected to one end of the intermediate connecting roller 6 through a coupling.

[0046] Specific implementation of the embodiments of this utility model, such as Figures 1 to 3 As shown, the circumferential high-pressure spray assembly includes a telescopic component 13, a pipe structure 14, a nozzle 15, a high-pressure pump 16, and a flexible hose 17.

[0047] The telescopic component 13 is fixed on the cover plate 5, and the telescopic component 13 is connected to the pipe structure 14. A hollow water injection cavity is formed between the inner wall and the outer wall of the pipe structure 14 (the water injection cavity is not shown in the figure, and the cross section of the pipe structure 14 can be any kind of circle or rectangle, as long as it does not obstruct the crankshaft from rising and falling).

[0048] Several sets of nozzles 15 are spaced apart along the height of the inner wall of the pipe structure 14 and are connected to the inside of the water injection chamber;

[0049] The high-pressure pump 16 is fixed in the upper area of ​​the cleaning tank 1, and the output end of the high-pressure pump 16 is connected to the water injection chamber through the flexible hose 17, and the input end of the high-pressure pump 16 is connected to the water tank (not shown in the figure).

[0050] In the specific implementation of this utility model embodiment, the two ends of the flexible hose 17 are respectively connected to the output end of the high-pressure pump 16 and the water injection cavity inside the pipe structure 14 through sealing joints. The sealing joints are not shown in the figure.

[0051] In order to know the liquid level inside the cleaning tank 1 from the outside of the cleaning tank so that the crankshaft can be fully immersed in the cleaning fluid for the subsequent second ultrasonic cleaning process, the above embodiment is further refined by providing a transparent observation window in the upper half of the front outer wall of the cleaning tank 1, and the transparent observation window is lower than the high-pressure pump 16.

[0052] It should be noted that the ultrasonic transducer 2, telescopic cylinder 4, sludge pump 8, servo motor 12, telescopic component 13, and high-pressure pump 16 are all electrically connected to the controller, which is not shown in the figure and is specifically installed on the outer wall of the cleaning tank 1.

[0053] The working process of this utility model:

[0054] First, the controller operates the two telescopic cylinders 4 to extend, thereby moving the cover plate 5 to a preset height (the initial position of the pipe structure 14 is as shown in the instruction manual). Figure 2 As shown, when the telescopic cylinder 4 extends, the telescopic component 13 also extends to prevent the pipe structure 14 from leaving the inside of the cleaning tank 1. This means that it does not hinder the subsequent installation of the crankshaft. Then, a crankshaft can be installed on each chuck 7 in sequence. When one end of the crankshaft is firmly clamped by the chuck 7, the telescopic cylinder 4 drives the cover plate 5 to move down and the retraction rod of the telescopic component 13 also retracts to avoid the pipe structure from contacting the inner wall of the cleaning tank and thus affecting the reset of the cover plate 5. Then, the other end of the crankshaft can pass through the pipe structure and enter the placement groove. It should be noted that when the other end of the crankshaft contacts the placement groove, the cover plate 5 is just in contact with the upper surface of the cleaning tank 1.

[0055] Then, by controlling the operation of the drive components through the controller, the synchronous rotation of several crankshafts can be achieved. At the same time, the high-pressure pump 16 is started to inject water into the water injection chamber in the pipe structure 14. Then, water is sprayed out from several nozzles 15 in multiple directions to clean the oil stains on the surface of the crankshaft during the rotation process. While cleaning, the telescopic component 13 can drive the pipe structure 14 to perform reciprocating lifting and lowering movements to further expand the high-pressure spraying area of ​​the crankshaft. As the high-pressure spraying proceeds, the liquid level in the cleaning tank 1 will gradually rise. When it is seen from the transparent observation window that the liquid level in the cleaning tank 1 is higher than the chuck 7, the spraying will stop. At this time, the crankshaft is completely immersed below the cleaning liquid surface. Then, by controlling the operation of the ultrasonic transducer 2 through the controller, the oil stains in the crankshaft oil passage holes can be effectively cleaned, thus improving the cleaning effect of the crankshaft. Ultrasonic cleaning can also further improve the cleaning effect of oil stains on the surface of the crankshaft.

[0056] After the crankshaft cleaning is completed, the telescopic cylinder 4 extends to drive the cover plate 5 to move upward. At the same time, the telescopic component 13 also extends, causing the crankshaft to detach from the pipe structure 14 and move outside the cleaning box 1. Then it can be dried naturally, or the drying time can be shortened by using an external hot air blower.

[0057] After drying is completed, several crankshafts are unlocked from chuck 7 and removed one by one. Finally, the wastewater after cleaning is transferred to the purification equipment by sludge pump 8 for purification. The purified water can be returned to the water tank for reuse. The water purification is not improved and is not the focus of this application, so it will not be described. After the wastewater is removed, a new round of crankshaft installation, cleaning and drying process can begin.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
