[0021] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Those skilled in the art should know that the following-described embodiments are a part of the present disclosure, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present utility model.

[0022] The quantity of any element in the accompanying drawings is for illustration rather than limitation, and any naming is only for distinction without any limiting meaning.

[0023] Next, with reference to several representative embodiments of the present utility model, the principles and spirits of the present utility model will be elaborated in detail.

[0024] A vertical abrasive disc for polishing provided by the present utility model, as Figures 1 to 3 shown, includes a disc body 1. The bottom of the disc is set as a bowl-shaped structure. An elastic base 2 and abrasive pages 3 are arranged on the bottom end face of the disc body 1. The elastic base 2 is abutted and bonded between the bottom end face of the disc body 1 and the abrasive pages 3. The abrasive pages 3 are inclined. There are several abrasive pages 3, and the several abrasive pages 3 are stacked in a circumferential direction. The abrasive pages 3 are set as a parallelogram structure, and grooves 31 are arranged on the abrasive pages 3.

[0025] By adopting the above technical solution, the abrasive disc 3 realizes an efficient and stable polishing effect, has stronger practicability. The grooves 31 can change the movement track of abrasive particles during the polishing process, making the abrasives more evenly distributed on the surface of the workpiece, thereby improving the uniformity and smoothness of the polished surface. The grooves 31 can also accommodate the tiny particles and debris generated during the polishing process, preventing them from reattaching to the surface of the workpiece and affecting the polishing quality, and also helps to guide the flow of debris, dust and coolant, enabling them to be discharged smoothly and keeping the working surface clean. The setting of the grooves 31 also helps to increase the contact area between the abrasive pages 3 and the air, improve the heat dissipation efficiency, reduce the damage to the material of the abrasive pages 3 caused by the high temperature generated by friction, and the elastic base 2 endows the abrasive pages 3 with a certain elasticity. This elasticity enables the abrasive pages 3 to make adaptive adjustments according to different surface shapes and textures during the polishing process, so as to achieve a better polishing effect.

[0026] In this embodiment, the grooves 31 are set as an inclined structure parallel to the side of the abrasive pages 3. In other embodiments, by adjusting the size, shape and distribution of the grooves 31, such as various forms of longitudinal, transverse, longitudinal and transverse combinations, etc., it is possible to adapt to different materials and processing requirements, and helps to guide the flow of the grinding medium and coolant during the grinding process, enabling them to better penetrate the surface of the workpiece and further improving the grinding quality and precision.

[0027] In this embodiment, the inclined side of the abrasive sheet 3 inclines towards the inner side of the disc body 1, so that the abrasive sheet 3 can maintain a certain stability during polishing and is not prone to deviation or detachment.

[0028] In this embodiment, the disc body 1 includes a mounting portion 11 and a connecting portion 12. The mounting portion 11 is provided with a first ventilation hole 111, and the connecting portion 12 is provided with a second ventilation hole 121. The diameter of the second ventilation hole 121 is larger than that of the first ventilation hole 111. In this embodiment, both the first ventilation hole 111 and the second ventilation hole 121 include a plurality of holes, and the plurality of first ventilation holes 111 and the plurality of second ventilation holes 121 are both evenly distributed along the circumferential direction. The connecting portion 12 plays a role of transition and support. The setting of the first ventilation hole 111 and the second ventilation hole 121 can make the heat dissipation effect of the disc body 1 better, which helps to better control the temperatures of the abrasive sheet 3 and the disc body 1 during the polishing process, ensuring the stability of the polishing process. Moreover, the increase in the diameter of the second ventilation hole 121 also helps to balance the air flow distribution inside the entire abrasive sheet 3 disc, realizing the effective guidance and distribution of the air flow, ensuring uniform heat dissipation, and the design of the larger ventilation holes can also reduce the noise generated when the air flows, improving the use experience.

[0029] In this embodiment, the disc body 1 is set as an annular structure. An extension section 13 is provided on the side of the mounting portion 11 facing the inner wall, and the extension section 13 extends vertically along the upper and lower sides of the mounting portion 11. It should be noted that during the use of the abrasive sheet 3 disc, the disc body 1 needs to be connected in a linkage manner to the transmission shaft that drives its rotation. The setting of the extension section 13 can increase the connection area between the mounting portion 11 and the transmission shaft, thereby improving the structural stability of the entire abrasive sheet 3 disc.

[0030] In this embodiment, a reinforcing member 14 is fixedly connected to the extension section 13. The reinforcing member 14 is inclined, and the end of the reinforcing member 14 away from the extension section 13 is fixedly connected to the connecting portion 12, which can further enhance the stability of the abrasive sheet 3 disc. During the polishing process, the abrasive sheet 3 and the disc body 1 need to bear large frictional forces and impact forces. The presence of the reinforcing member 14 can effectively disperse these forces and prevent the abrasive sheet 3 disc from deforming or being damaged.

[0031] In this embodiment, the reinforcing member 14 is set as a rod-shaped structure, and the reinforcing member 14 includes a plurality of members, avoiding affecting the air flow inside the disc body 1 and the first ventilation hole 111 and ensuring the practicability of the abrasive sheet 3 disc.

[0032] Based on the above description of this specification, those skilled in the art can also understand the terms used as follows. For example, terms indicating orientation or positional relationships such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings of this specification. They are only for the purpose of facilitating the description of the solution of the present utility model and simplifying the description, rather than explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operate in the specific orientation. Therefore, the above terms of orientation or positional relationships cannot be understood or interpreted as limitations on the solution of the present utility model.

[0033] In addition, in the description of this specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise specifically and clearly defined.
