[0002] Aluminum alloy wheels typically refer to car wheel rims made of aluminum alloy materials. Due to their advantages such as lightweight, high strength, and aesthetics, they are widely used in vehicles such as cars and motorcycles. Polishing is one of the processes in the manufacturing of aluminum alloy wheels, and its purpose is to remove the surface oxide layer and scratches and create a mirror effect.

Over time, this can lead to wheel positioning deviations, affecting polishing accuracy. Furthermore, manual cleaning of the aluminum shavings is required periodically, reducing production efficiency. Therefore, a new aluminum alloy wheel polishing jig is proposed to address these issues. Utility Model Content

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] Reference Figures 1-5 As shown, an aluminum alloy wheel polishing fixture includes a frame 1, a clamping table 2 fixedly connected to the upper end of the frame 1, a three-jaw chuck 3 fixedly connected to the upper end of the clamping table 2, a baffle 4 fixedly connected to the upper edge of the clamping table 2, a blower plate 5 fixedly connected between the front inner wall and the rear inner wall of the baffle 4, the lower end of the blower plate 5 fixedly connected to the upper end of the clamping table 2, an air conveying hood 7 fixedly connected to the right end of the blower plate 5, a connecting pipe 8 fixedly connected to the right end of the air conveying hood 7, a centrifugal fan 9 fixedly connected to the right end of the connecting pipe 8, and the centrifugal fan 9 fixedly connected to the upper end of the frame 1. A chip collection groove 10 and a through groove 11 are both opened through the upper ends of the frame 1 and the clamping table 2. A telescopic groove 12 is opened on the left inner wall of the frame 1, and a material guiding component 13 is arranged inside the telescopic groove 12. A slot is opened through the right end of the frame 1, and a collection box 16 is inserted into the slot.

[0026] The material guiding assembly 13 includes several springs 1301 fixedly connected to the bottom of the inner side of the telescopic groove 12, and a material guiding plate 1302 fixedly connected to the upper end of the springs 1301.

[0027] Furthermore, the three-jaw chuck 3 utilizes the radial movement of three movable jaws evenly distributed on the chuck to abut against the inner ring of the wheel, thereby clamping and fixing the wheel.

[0028] Furthermore, the baffle 4 has a certain height to shield the aluminum chips generated during the polishing process and prevent the chips from splashing and scattering onto the clamping table 2.

[0029] Furthermore, the blower plate 5 has a hollow structure, with several evenly distributed air outlets 6 extending through the left end of the blower plate 5. The air supply hood 7 is connected to the interior of the blower plate 5. When the centrifugal fan 9 is working, the high-speed airflow generated enters the air supply hood 7 through the connecting pipe 8, and then enters the internal cavity of the blower plate 5. Since the blower plate 5 has evenly distributed air outlets 6 at the left end, the airflow is blown out at high speed from the air outlets 6, forming an air curtain. When the aluminum chips generated during polishing fall onto the clamping table 2, the air curtain blows the aluminum chips toward the chip collection groove 10. Through this air blowing method, the aluminum chips are prevented from accumulating on the clamping table 2 and the three-jaw chuck 3, ensuring the positioning accuracy and polishing quality of the wheel.

[0030] Furthermore, the position of the through groove 11 corresponds to the hollow part in the middle of the three-jaw chuck 3, to prevent debris from accumulating in the hollow part.

[0031] Furthermore, a drive groove 14 is provided at the upper end of the telescopic groove 12, a motor 1304 is fixedly installed at the front end of the frame 1, a rotating shaft 1305 is fixedly connected to the output end of the motor 1304, the other end of the rotating shaft 1305 passes through the front inner wall of the drive groove 14 and is rotatably connected to the rear inner wall of the drive groove 14, an eccentric wheel 1306 is fixedly connected to the outer surface of the rotating shaft 1305, and the eccentric wheel 1306 is rotatably connected to the inside of the drive groove 14, and a blocking block 1303 is fixedly connected to the upper end of the guide plate 1302 near the telescopic groove 12.

[0032] Furthermore, after the debris is blown towards the chip collection trough 10 by the air curtain, it will fall onto the guide plate 1302 through the chip collection trough 10. When the motor 1304 starts, it will drive the rotating shaft 1305 and the eccentric wheel 1306 to rotate. Due to the eccentric structure of the eccentric wheel 1306, it will generate a periodic force on the guide plate 1302 during rotation. Combined with the elastic force of the spring 1301, the guide plate 1302 will generate a high-frequency vibration amplitude, so that the aluminum chips can smoothly slide down the guide plate 1302 to the collection box 16. The baffle block 1303 is installed at the upper end of the guide plate 1302 near the telescopic groove 12, which can prevent the aluminum chips from splashing into the telescopic groove 12 during vibration and ensure the stability of the guide assembly 13 during long-term use.

[0033] Furthermore, a positioning plate 15 is fixedly connected to the bottom inner side of the frame 1, and the left end of the collection box 16 abuts against the right end of the positioning plate 15.

[0034] Furthermore, the collection box 16 is used to collect debris during the processing. The debris can be removed by pulling the collection box 16 outward, which facilitates the unified cleaning and recycling of the debris.

[0035] Working principle: During use, the wheel is placed on the outside of the three-jaw chuck 3. The wheel is fixed by the three jaws of the three-jaw chuck 3 abutting against the inner ring of the wheel. Then, the polishing assembly is activated to polish the front of the wheel. During the polishing process, the high-speed airflow generated by the centrifugal fan 9 enters the air supply hood 7 through the connecting pipe 8, and then enters the internal cavity of the blower plate 5. Since the blower plate 5 has evenly distributed air outlets 6 at the left end, the airflow is blown out at high speed from the air outlets 6, forming an air curtain. When the aluminum chips generated during polishing fall onto the clamping table 2, the air curtain blows the aluminum chips towards the chip collection groove 10. After the debris is blown by the air curtain to the chip collection trough 10, it falls onto the guide plate 1302. At this time, the motor 1304 drives the rotating shaft 1305 and the eccentric wheel 1306 to rotate. Due to the eccentric structure of the eccentric wheel 1306, it will generate a periodic force on the guide plate 1302 during rotation. Combined with the elastic force of the spring 1301, the guide plate 1302 will generate high-frequency vibration amplitude, so that the aluminum chips can smoothly slide down the guide plate 1302 into the collection box 16, which not only ensures the processing environment, but also facilitates the recycling of the debris.

[0036] 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 embodiments and descriptions in the specification are merely 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 the claimed utility model.
