Description

Technical Field

[0001] This utility model relates to the field of polishing discs, and more particularly to an electric polishing disc. Background Technology

[0002] Polishing machines, also known as grinding machines, are often used for mechanical grinding, polishing, and waxing. Their working principle is as follows: an electric motor drives a polishing disc mounted on the polishing machine to rotate at high speed. Due to the combined action of the polishing disc and polishing agent, and the friction between them and the surface to be polished, the purpose of removing contaminants, oxide layers, and shallow scratches can be achieved, thereby improving surface cleanliness and surface quality. Depending on the material to be polished, polishing discs of different hardness can be selected as needed, such as crystal polishing discs, wool polishing discs, and velvet polishing discs.

[0003] Existing polishing pads typically have the following problems:

[0004] Firstly, when the polishing disc is used in conjunction with the polishing machine, uneven weight distribution can easily occur during high-speed rotation, causing significant vibration of the polishing machine body and preventing it from working properly.

[0005] Secondly, during the high-speed rotation of the polishing disc in conjunction with the polishing machine, the mating surfaces may not be parallel, resulting in significant vibration of the polishing machine body and preventing it from working properly.

[0006] Third, polishing discs need to be used with sandpaper. The dust extraction holes of existing polishing discs on the market are generally simple and the sandpaper is not well compatible.

[0007] Fourth, dust often adheres to the sandpaper during the operation of existing polishing pads, resulting in a decrease in cutting force and a reduction in the lifespan of the sandpaper. Utility Model Content

The external polishing machine drives the transmission wheel to rotate, and the transmission wheel drives the main body to rotate.

[0012] Preferably, the inner wall of the mounting interface and the inner wall of the transmission wheel are connected to form a recessed structure for smooth rotation of the body, and the recessed structure is compatible with various external polishing machine connectors.

[0013] Preferably, the suction hole unit includes a first suction hole on the suction plate, a second suction hole on the polishing plate, a third suction hole on the fixed plate, and a fourth suction hole on the chassis.

[0025] like Figures 1 to 3As shown, this utility model provides an electric polishing disc, including a body, which includes a polishing disc 1. On one side of the polishing disc 1, an air suction disc 2 and an outer ring disc 3 are fixed sequentially from the inside to the outside. On the other side of the polishing disc 1, a fixing disc 4 and a base plate 5 are fixed sequentially from the inside to the outside. Specifically, a gravity adjustment unit is embedded and fixed in the air suction disc 2 to make the weight distribution of the body uniform and the rotation stable, so as to achieve a more stable high-speed rotation. An air suction channel 6 is formed between the inner side of the outer ring disc 3 and the surface of the air suction disc 2 to disperse the suction force at the center of the body, further stabilizing the high-speed rotating body.

[0026] The main body is provided with several suction hole units for air and dust extraction. The back of the polishing disc 1 and the fixing disc 4 are provided with groove units for forming air circulation and preventing dust from adhering to the sandpaper. Specifically, the groove unit extends from the center to the outside and includes at least two arc-shaped recesses 7 that communicate with the suction hole units. The side of the polishing disc 1 and the fixing disc 4 near the base 5 is the working surface for connecting the sandpaper and performing polishing work. The arc-shaped recesses 7 are formed on the working surface and communicate with the suction channel at the front end to form air circulation, achieving a better dust extraction effect on the working surface, making it less likely for dust to adhere to the working surface, and improving the service life of the sandpaper.

[0027] The suction plate 2 has a mounting interface 8 at its center for connecting to an external polishing machine. A transmission wheel 9 that cooperates with the mounting interface 8 is fixed inside the suction plate 2. Specifically, the transmission wheel 9 has a through hole 10. The external polishing machine is connected to the through hole 10. The external polishing machine drives the transmission wheel 9 to rotate, and the transmission wheel 9 drives the main body to rotate.

[0028] The inner wall of the mounting interface 8 and the inner wall of the transmission wheel 9 are connected to form a recessed structure 11 for stabilizing the rotation of the main body. The recessed structure 11 is compatible with various external polishing machine connectors, avoiding the situation where the polishing machine body shakes significantly and cannot work properly due to the non-parallel connection surfaces between the polishing machine and the main body. This makes the high-speed rotation of the main body more stable and also adapts to more polishing machine models.

[0029] The suction hole unit includes a first suction hole 12 on the suction plate 2, a second suction hole 13 on the polishing plate 1, a third suction hole 14 on the fixing plate 4, and a fourth suction hole 15 on the base plate 5. Specifically, the first suction hole 12, the second suction hole 13, the third suction hole 14, and the fourth suction hole 15 are arranged correspondingly, and the suction hole unit includes multiple suction hole types. The arc recess 7 is connected to the second suction hole 13 and the third suction hole 14 respectively. The multi-position and multi-hole design improves the adaptability of sandpaper installation.

[0030] The suction disk 2 is provided with a first suction channel 16 that cooperates with the first suction hole 12, and the polishing disk 1 is provided with a second suction channel 17 that cooperates with the second suction hole 13. Both the first suction channel 16 and the second suction channel 17 are connected to the arc recess 7. Specifically, the first suction channel 16 is arranged on the side close to the outer ring disk 3, and the second suction channel 17 is arranged on the side close to the suction disk 2.

[0031] The advantages of this utility model are:

[0032] 1. The machine body rotates smoothly during operation, which helps to improve grinding efficiency;

[0033] 2. The polished surface design meets the requirements of various scenarios and is compatible with most sandpapers;

[0034] 3. Increased sandpaper lifespan reduces customer usage costs.
