DETAILED DESCRIPTION

[0017] Reference Attachment Figure 1-3 The utility model discloses a three-chamber combined cleaning device for automobile axles before painting, which is used to clean the axles before painting. The device comprises a combined body 1, wherein a feed port 5 and a discharge port 6 for feeding and discharging workpieces 20 are respectively provided at both ends of the combined body, and a cleaning channel 7 is provided along the length direction inside the combined body, wherein the feed port and the discharge port are respectively provided at both ends of the cleaning channel;

[0018] The combined machine body is provided with a degreasing chamber 2, a hot water washing chamber I 3, a hot water washing chamber II 4, and a conveying system for lifting the automobile axle. Under the action of the conveying system, the axle passes along the cleaning channel and sequentially passes through the degreasing chamber, the hot water washing chamber I, and the hot water washing chamber II to complete the cleaning and rinsing process.

[0019] The degreasing chamber, hot water wash chamber I, and hot water wash chamber II are each equipped with a water tank 8, a spray pipe 9, and a nozzle 10. The water tank is located outside the combined machine body. Multiple spray pipes are provided, each equipped with multiple nozzles directed toward the workpiece. Each spray pipe is secured to the combined machine body and connected to the corresponding water tank via a pipeline equipped with a high-pressure water pump 11 and a control valve. The water tank corresponding to the degreasing chamber contains a degreaser to effectively clean grease and other substances from the workpieces. The water tank corresponding to hot water wash chamber I can contain a standard detergent to improve cleaning effectiveness against common stains, or, like the water tank corresponding to hot water wash chamber II, can be filled with clean water to rinse the workpieces.

[0020] Preferably, the conveying system includes a track 12 disposed on a combined machine body, a roller assembly cooperating with the track, and a suspension chain 13 cooperating with the roller for suspending the axle; and also includes a drive chain for driving the roller assembly, the drive chain being connected to the roller assembly. The track can be I-shaped, the roller assembly includes two rollers 14 cooperating with the track, and a C-shaped roller frame 15 connecting the two rollers. The upper end of the suspension chain is fixed to the roller frame, and the lower end is connected to the workpiece via a lock or hook 16. The drive chain can be connected to the roller frame of the roller assembly, and the drive chain is connected to a drive motor with a drive sprocket. The specific connection method of the drive chain, the drive motor, and the roller assembly is based on existing technology and is preferably not affected by the drive.

[0026] The specific working process of the utility model structure is as follows:

[0027] The axle is manually suspended from a suspension conveyor chain and automatically conveyed by a conveyor system into the cleaning area's feed port, the degreasing chamber. After the degreasing chamber's water tank temperature and spray pressure are set, the spray system begins operating, spraying the axle from adjustable nozzles located on the upper, lower, left, right, front, and rear spray pipes. The axle is then driven by the conveyor system into the rinsing area, namely Hot Water Wash I and Hot Water Wash II. First, Hot Water Wash I undergoes a full-scale hot water spray wash. After Hot Water Wash I, the conveyor system automatically transfers the axle to Hot Water Wash II, where it undergoes a full-scale hot water spray wash, similar to Hot Water Wash I. Mist generated during the degreasing / hot water wash I / II processes is exhausted to the outside by exhaust fans at both ends of the combined unit. The axle is then transported by the conveyor system to the subsequent pre-painting station, completing the entire pre-painting cleaning process. After cleaning, the workpiece can be dried as needed and then transferred to the next step.
