[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without making creative efforts fall within the protection scope of the present utility model.

[0020] The number of any elements in the drawings is for illustration rather than limitation, and any naming is only for distinction without any limiting meaning.

[0021] Next, the principles and spirit of the present utility model will be elaborated in detail with reference to several representative embodiments of the present utility model.

[0022] A drum - type abrasive - paper polishing wheel provided by the present utility model, as Figures 1 to 3 shown, includes a wheel core 1 and a transmission shaft 2. The wheel core 1 is arranged in a hemispherical structure. Both the upper and lower end faces of the wheel core 1 are flat planes, and the side wall of the wheel core 1 is an arc - shaped curved surface. The outer wall of the wheel core 1 is sequentially provided with an elastic base 11 and abrasive papers 12 from the inside to the outside. Both the elastic base 11 and the abrasive papers 12 are arranged in arc - shaped structures corresponding to the outer wall of the wheel core 1. There are several abrasive papers 12, and the several abrasive papers 12 are evenly distributed along the circumferential direction on the outer wall of the elastic base 11 layer. The wheel core 1 is sleeved on the outer wall of the transmission shaft 2 and is detachably connected to the transmission shaft 2.

[0023] By adopting the above - mentioned technical solution, the polishing wheel can better meet the polishing requirements of various irregular surfaces. The hemispherical structure can better fit the curved surface, improve the polishing efficiency and uniformity, enable the polishing quality of the workpiece to be higher and the polishing effect to be better. And the elastic base 11 can enable the abrasive papers 12 to have a certain buffering effect during the polishing process, reduce the possible scratches or damages caused by hard contact. At the same time, the elastic base 11 can also enable the abrasive papers 12 to better fit the surface of the workpiece, further improve the polishing effect, and make the practicability of the polishing wheel stronger.

[0024] In this embodiment, both the inner and outer end faces of the abrasive paper 12 are arc - shaped structures. The arc - shaped curves in the vertical cross - sections of the outer wall of the wheel core 1, the elastic base 11, and the outer wall of the abrasive paper 12 are all semi - circular curves, which further improves the polishing effect, service life, and structural stability of the drum - type abrasive - paper 12 polishing wheel. In other embodiments, according to the actual use situation, the arc - shaped curves in the vertical cross - sections of the outer wall of the wheel core 1, the elastic base 11, and the outer wall of the abrasive paper 12 can also be set as major - arc curves or minor - arc curves.

[0025] In this embodiment, the wheel core 1, the elastic base 11, and the abrasive sheet 12 are all adhesively connected to ensure the practicability of the polishing wheel. The adhesive connection can achieve a tight fit between layers, so that during the polishing process, stress can be evenly distributed among the layers, which helps to reduce damage caused by stress concentration and improve the durability of the polishing wheel. It should be noted that when selecting an adhesive, it is necessary to ensure that it has sufficient adhesive strength and durability. At the same time, attention should also be paid to controlling factors such as temperature and pressure during the adhesive process to ensure the quality and stability of the connection.

[0026] In this embodiment, the wheel core 1 includes a first mounting portion 13 and a second mounting portion 14. The first mounting portion 13 is a hemispherical structure, and the first mounting portion 13 is symmetrically distributed on both sides of its horizontal central axis. The second mounting portion 14 is located at the end of the first mounting portion 13. The second mounting portion 14 is provided with a mounting hole 141. The transmission shaft 2 passes through the wheel core 1, and a first mounting groove 21 corresponding to the mounting hole 141 is provided on the transmission shaft 2. A locking screw 142 is threadedly connected in the mounting hole 141, and the locking screw 142 is in abutting cooperation with the first mounting groove 21 to achieve a detachable connection between the wheel core 1 and the transmission shaft 2. Moreover, the mounting hole 141 penetrates through the second mounting portion 14, which can hide the locking screw 142 and further increase the practicability of the polishing wheel.

[0027] In this embodiment, there are several first mounting grooves 21. The several first mounting grooves 21 are evenly distributed along the vertical direction on the outer wall of the transmission shaft 2. The transmission shaft 2 passes through the wheel core 1, and the accurate positioning of the wheel core 1 during installation is achieved through the first mounting grooves 21 corresponding to the mounting holes 141. The wheel core 1 can be replaced with different sizes according to actual use requirements. The wheel cores 1 of different sizes are fixedly connected to different first mounting grooves 21 through the locking screws 142.

[0028] In this embodiment, a second mounting groove 131 is provided on the inner wall of the first mounting portion 13, and a third mounting groove 22 corresponding to the second mounting groove 131 is provided on the outer wall of the transmission shaft 2. An anti - detachment member 132 is provided in the second mounting groove 131. The anti - detachment member 132 is in an interference fit with both the second mounting groove 131 and the third mounting groove 22, which can effectively increase the stability of the wheel core 1 mounted on the transmission shaft 2. It should be noted that the position of the second mounting groove 131 in the wheel cores 1 of different sizes is fixed, and there is no need to provide multiple third mounting grooves 22 on the transmission shaft 2.

[0029] In this embodiment, a limiting member 23 is provided at one end of the transmission shaft 2 facing the wheel core 1. The diameter of the limiting member 23 is larger than the inner diameter of the wheel core 1 and smaller than the outer diameter of the wheel core 1. The wheel core 1 is in abutting cooperation with the limiting member 23, which can further increase the stability of the connection between the wheel core 1 and the transmission shaft 2.

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 invention 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 invention.

[0031] 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 defined.
