[0002] In new energy vehicles, the differential housing, or simply "differential housing," is the external structure of the differential. It is usually made of high-strength metal material and is generally produced by casting (material is ductile iron 600-3). It is used to protect the gears and other components inside the differential and prevent dust, moisture and other contaminants from entering.

[0003] After processing, cast iron parts have residual iron filings, oil stains, and dust on their surface. Due to the special structure of this product, there is a lack of special cleaning equipment on the market. The main method is to clean it manually with a special cleaning solution, then blow it dry with an air gun and let it air dry naturally.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-6 The present invention provides a technical solution: A special cleaning equipment for machining differential housing parts of new energy vehicles includes a cleaning tank 1, a conveying mechanism and a part picking platform 5. The part picking platform 5 is set on the side of the cleaning tank 1 and is used for workpiece transfer and connection. The cleaning tank 1 is equipped with a rotating disk 12 that can rotate around its own axis. Several sets of snap-fit ​​seats are evenly distributed along the circumferential direction on the upper surface of the rotating disk 12. The snap-fit ​​seats are used for internal support fixation from the inner cavity of the differential housing. The cleaning tank 1 is also equipped with a spray cleaning component and a drying component. The spray cleaning component is used to spray cleaning fluid onto the differential housing. The rotating disk 12 is equipped with an internal ventilation duct. The output end of the drying component is rotatably connected to the air inlet end of the internal ventilation duct. The air outlet end of the internal ventilation duct is correspondingly set at each set of locking seats to deliver drying airflow to the inner cavity of the fixed differential housing. The pickup platform 5 is equipped with a transfer frame 11. The conveying mechanism includes a first conveyor platform 3 and a second conveyor platform 6. The first conveyor platform 3 and the second conveyor platform 6 are arranged at a 90-degree angle around the pickup platform 5. The transfer frame 11 is used to transfer the differential housing to be cleaned from the first conveyor platform 3 to the pick-up platform 5 to the clamping seat in the cleaning tank 1, and to transfer the cleaned differential housing from the clamping seat to the pick-up platform 5 and then to the second conveyor platform 6.

[0022] In this invention, the differential housing is conveyed to the transfer frame 11 of the pick-up platform 5 via the conveyor platform 3. The transfer frame 11 conveys the differential housing to the clamping seat of the cleaning tank 1 (the lifting seat 13 of the transfer frame 11 rotates to adjust the angle, and a set of clamping rings 15 is responsible for grabbing the workpiece to be cleaned from the conveyor platform 3; at the same time, another set of clamping rings 15 are aligned with the empty clamping seat in the cleaning tank 1, and the workpiece to be cleaned falls onto the clamping seat by flipping the clamping rings 15). The clamping seat fixes the differential housing to the rotating disk 12 (the telescopic rod 18 extends, the support claw 19 pops out and tightens the inner wall of the housing to complete the fixation, realizing the simultaneous picking and unloading of one set of materials). By rotating the rotating disk 12, the clamping seat is rotated to the position of the movable door 101, thereby completing the fixation of multiple sets of differential housings in sequence, so that the cleaning tank 1 can clean multiple sets of differential housings at the same time. After loading multiple sets of differential housings, the movable compartment door 101 is closed, and the rotating differential housings are subjected to high-pressure spraying by the spray cleaning assembly to remove surface iron filings, oil stains and dust; after cleaning, the differential housings are dried by the drying assembly.

[0023] This invention addresses the challenges of complex internal structures and the tendency for iron filings and oil stains to accumulate in the corners of differential housings. It employs an internal support type clamping seat to fix the differential housing within the workpiece cavity, eliminating external surface clamping and obstruction. Combined with a rotating spray system, it achieves full-coverage cleaning of the housing's outer surface. Simultaneously, the internal ventilation pipes built into the rotating disc 12 directionally deliver drying airflow into the housing cavity, solving the problem of traditional manual air guns failing to thoroughly clean the corners. The cleaning and drying effects are uniform and controllable, resulting in high consistency in surface finish during batch processing and avoiding quality variations caused by manual operation.

[0024] The circular station rotating disk 12 structure in this invention can simultaneously load multiple differential housings for continuous cleaning and drying operations. Combined with the 90-degree layout of the loading and unloading conveyor line and the dual-station transfer frame 11, it can realize the fully unmanned operation of automatic workpiece loading, automatic clamping, automatic cleaning and drying, and automatic unloading, replacing the multiple steps of manual cleaning, air gun drying, and natural air drying, significantly shortening the processing time of a single workpiece, reducing labor costs, and adapting to the mass production line requirements of new energy vehicle parts.

[0025] The locking seat includes a positioning plate 17, a telescopic rod 18, and at least two sets of support claws 19. The positioning plate 17 is fixedly installed on the upper surface of the rotating plate 12, and a circular through groove is opened in the center of the positioning plate 17. The telescopic rod 18 is vertically fixed below the positioning plate 17, and the movable end of the telescopic rod 18 passes upward through the circular through groove. Each set of support claws 19 is rotatably installed on the top of the movable end of the telescopic rod 18 by a torsion spring. When the telescopic rod 18 drives the support claws 19 to move upward above the circular through groove, the support claws 19 unfold outward under the action of the torsion spring and are tightened against the inner wall of the differential housing to achieve fixation. In this invention, when the telescopic rod 18 is in the retracted state, the support claw 19 is housed in the circular through groove along with the movable end. The side wall of the through groove restricts the expansion of the support claw 19, and the overall outer diameter is smaller than the inner cavity opening of the differential housing. When the telescopic rod 18 extends and drives the support claw 19 to move upward above the circular through groove, the support claw 19 loses the side wall constraint and automatically expands outward under the action of the torsion spring, bracing against the inner wall of the differential housing, thereby achieving the centering and fixation of the workpiece.

[0026] The drying assembly includes a dryer 7 and an air inlet pipe 8. The dryer 7 is fixedly installed on the top of the cleaning tank 1 and is used to output hot drying air. The air inlet pipe 8 includes a wide-face mask 801 and a fixed pipe 802. The upper end of the fixed pipe 802 is connected to the output end of the dryer 7, and the lower end of the fixed pipe 802 is fixedly connected to the wide-face mask 801. The lower end of the wide-face mask 801 is embedded in the center of the rotating disk 12 and is rotatably and sealingly connected to the rotating disk 12. The air inlet ends of the internal ventilation pipes are all located within the coverage area of ​​the wide-face mask 801. The dryer 7 of this invention is fixedly installed on the outer side of the top wall of the cleaning tank 1 and is used to output heated hot drying air.

[0027] The internal ventilation system includes multiple sets of internal pipes 22 corresponding to the locking seats. One end of each set of internal pipes 22 converges at the center of the rotating disk 12 and communicates with the inner cavity of the wide-face mask 801, while the other end extends to the corresponding positioning disk 17 to form an air outlet. An elastic plug 16 is provided at the air outlet. The elastic plug 16 blocks the air outlet when there is no air pressure, and opens under the pressure of the drying airflow to guide airflow into the inner cavity of the differential housing. In this invention, each air outlet of the internal pipe 22 is provided with an elastic plug 16 at its end. The elastic plug 16 is reset by a spring. When there is no external air pressure, the spring pushes the elastic plug 16 to block the air outlet, preventing cleaning fluid and metal debris from entering the internal pipe 22.

[0028] The bottom of the cleaning tank 1 is fixedly provided with a lower mounting box 2. The interior of the lower mounting box 2 is divided into a first chamber and a second chamber by a partition. A drive motor 20 is fixedly installed in the first chamber. The output shaft of the drive motor 20 extends upward into the cleaning tank 1 and is fixedly connected to the center of the rotating disk 12. It is used to drive the rotating disk 12 to rotate at a uniform speed. A mechanical dynamic seal structure is provided between the output shaft and the cleaning tank 1 to seal this part. The mechanical dynamic seal structure adopts a conventional sealing structure in this field.

[0029] The second chamber contains cleaning fluid and a heating element 21, composed of multiple electric heating tubes, is fixedly installed inside. This heating element 21 heats the cleaning fluid. A water storage tank 9 is fixedly installed on the upper surface of the lower mounting box 2, and its bottom is connected to the second chamber via a connecting pipe. The second chamber and the cleaning tank 1 are connected by a water guide pipe 10, which transports the heated cleaning fluid to the spray cleaning assembly. The heating element 21, composed of multiple sets of parallel electric heating tubes, is fixedly installed inside the second chamber to maintain a constant temperature for the cleaning fluid, improving the oil stain cleaning effect. A water pump is installed on the water guide pipe 10, which drives water into the spray cleaning assembly.

[0030] The transfer frame 11 includes a lifting base 13, an intermediate connecting plate 14, and two sets of locking rings 15. The lifting base 13 is rotatably mounted on the picking platform 5, which is equipped with a transfer motor to drive the lifting base 13 to rotate horizontally. The intermediate connecting plate 14 is rotatably mounted on the upper end of the lifting base 13, and the two sets of locking rings 15 are rotatably mounted on both ends of the intermediate connecting plate 14. The locking rings 15 are annular structures with a constricted lower end. A micro motor is provided on the intermediate connecting plate 14 corresponding to each set of locking rings 15. The micro motor is used to drive the locking rings 15 to rotate up and down to grab or release the differential housing. The locking rings 15 of this invention are annular structures with a constricted lower end, and their constricted size is smaller than the maximum outer diameter of the differential housing, which can support the bottom of the housing to complete the grabbing. The design of the double sets of locking rings 15 can realize synchronous operation of picking and unloading materials, improving work efficiency.

[0031] The cleaning tank 1 has a movable door 101 on the side near the unloading platform 5. The edge of the movable door 101 is equipped with a sealing strip to close the cleaning tank 1 during cleaning operations. Both the first conveyor platform 3 and the second conveyor platform 6 are supported by the lower mounting frame 4. During cleaning operations, the movable door 101 is closed, forming a closed space inside the cleaning tank 1 to prevent cleaning fluid from splashing and heat loss.

[0032] The cleaning tank 1 has a control panel on its outer side. The control panel is electrically connected to the drive motor 20, dryer 7, heating element 21, and transfer frame 11, and is used to regulate the cleaning, drying, and transfer operation parameters of the equipment. The cleaning tank 1 of this invention has a control panel on its outer side, which is electrically connected to all electrical components inside the equipment, and is used to regulate operation parameters such as cleaning time, drying temperature, rotation speed, and transfer cycle time.
