[0002] A wheel grinding and polishing machine is a specialized piece of machinery designed to grind and polish the surface of wheels to improve their appearance and surface finish. Driven by a motor, it uses various types of abrasives and polishing materials, such as grinding wheels, sandpaper, polishing discs, and polishing wax, to remove imperfections, casting marks, scratches, and other defects from the wheel surface. Through grinding and polishing, the wheel surface gradually becomes smooth and even, ultimately achieving a bright, new-looking finish. It is widely used in automobile manufacturing, repair and maintenance, and wheel refurbishment.

[0003] For example, the polishing machine disclosed in Chinese Patent Publication No. CN219094634U includes a fixed frame, a motor fixedly connected inside the fixed frame, and a polishing wheel detachably and fixedly connected to the drive shaft of the motor; a water spraying component, which is set inside the fixed frame and is used to spray liquid when the polishing wheel rotates; and an angle adjustment component, which is set inside the fixed frame and is used to adjust the circumferential angle of the water spraying component inside the fixed frame.

[0004] Existing integrated grinding and polishing machines require a dust removal operation after grinding wheel hubs. During this process, the dust removal air carries metal debris and dust from the wheel hub surface into the rotary drive assembly. Over time, a certain amount of metal debris and dust accumulates inside the rotary drive assembly, which adversely affects the normal operation of the assembly, leading to malfunctions, severely impacting the stability and lifespan of the equipment, and increasing maintenance costs and downtime.

A shavings collection assembly 62 is fixedly connected to one side of the shavings collection groove 61. A wheel hub support ring 3 is fixedly installed on the outer side of one end of the wheel hub positioning rod 3. 1. One end of the hub positioning rod 3 is threadedly connected to the hub pressing plate 32. The hub support ring 31 is set between the metal debris collection plate 6 and the hub pressing plate 32. The wind-powered dust removal assembly 7 includes a drive cylinder 71, a mounting platform 72 and a wind-powered dust collector 73. The drive end of the drive cylinder 71 is fixedly connected to one end of the mounting platform 72. The wind-powered dust collector 73 is fixedly welded to the other end of the mounting platform 72. The wind-powered dust collector 73 includes a mounting frame 731 and an air supply pipe 732. The air supply pipe 732 is fixedly connected to one end of the mounting frame 731. The other end of the air supply pipe 732 is fixedly connected to an air storage chamber 733. Several branch air pipes 734 are fixedly connected to the outside of the air storage chamber 733.

[0023] The specific settings and functions of this embodiment are described below. The wheel hub to be polished is placed above the wheel hub support ring 31. Then, the wheel hub pressing plate 32 is rotated to position the wheel hub. The polishing robot arm 4 performs the polishing operation on the wheel hub. At the same time, the drive motor in the rotary drive assembly 2 drives the wheel hub positioning rod 3 to rotate and adjust the wheel hub. After the polishing operation is completed, the drive cylinder 71 drives the wind dust collector 73 to slide forward, so that the output end of the air supply pipe 732 is located at the center of the wheel hub. The wind dust is used to remove dust from the surface of the wheel hub, blowing the metal debris and dust attached to the surface of the wheel hub into the interior of the metal debris collection plate 6. The metal debris and dust will accumulate inside the debris collection groove 61 and enter the interior of the debris collection assembly 62, thereby preventing dust from falling into the interior of the rotary drive assembly 2, protecting the rotary drive assembly 2, and thus improving the stability and service life of the equipment.

[0024] Example 2: Figure 1 - Figure 4 As shown, the debris collection assembly 62 includes several debris collection pipes 621, a debris collection ring 622, and a debris discharge pipe 623.

Several discharge ports 611 are provided inside the debris collection trough 61, and the other ends of the debris collection pipes 621 are fixedly connected to the several discharge ports 611 respectively.

[0025] The overall effect of this embodiment is that metal shavings enter the interior of the shavings collection pipe 621 through the discharge port 611, and then enter the interior of the shavings collection ring 622 through the shavings collection pipe 621. After the individual hub has been polished, the piston at the other end of the shavings discharge pipe 623 is removed, and the metal shavings dust inside the shavings discharge pipe 623 is poured out. Workers collect the metal shavings dust to prevent the shavings collection component 62 from storing excessive metal shavings dust and spraying it out in reverse from the discharge port 611.

[0026] The device is used and works as follows: Place the wheel hub to be polished above the wheel hub support ring 31, then rotate the wheel hub pressing plate 32 to position the wheel hub. The polishing robot arm 4 polishes the wheel hub. At the same time, the drive motor in the drive assembly 2 drives the wheel hub positioning rod 3 to rotate and adjust the wheel hub. After the polishing operation is completed, the drive cylinder 71 drives the wind dust collector 73 to slide forward, so that the output end of the air supply pipe 732 is located at the center of the wheel hub, and the surface of the wheel hub is dusted by wind. The metal debris and dust attached to the surface of the wheel hub are blown into the interior of the metal debris collection plate 6. The metal debris and dust will accumulate in the interior of the debris collection groove 61 and enter the interior of the debris collection assembly 62.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
