[0039] Please refer to Figures 1 to 5, this embodiment provides a grinding wheel, which includes a base body 1 and grinding blocks 2. A plurality of grinding blocks 2 arranged in a circumferential array are provided on one end face of the base body 1. The grinding wheel further includes a plurality of positioning devices 3. The positioning devices 3 are arranged on the end face of the base body 1 that supports the grinding blocks 2. One positioning device 3 corresponds to one grinding block 2. The positioning device 3 contacts the grinding block 2 and is used to determine the position of the grinding block 2.

[0040] First, install the positioning device 3 on one end face of the base body 1. Then, determine the position of the grinding block 2 according to the position of the positioning device 3, and install the grinding block 2 on one end face of the base body 1 so that it contacts one side of the positioning device 3. The presence of the positioning device 3 greatly improves the positioning accuracy of the grinding block 2, enabling the grinding wheel to maintain higher stability and consistency during the processing. Since the position of the grinding block 2 is precisely controlled, the processing errors caused by the inaccurate position of the grinding block 2 are reduced, the processing quality is improved, and thus the quality of the product can be improved.

[0041] Please refer to Figures 1 to 4 , in this embodiment, the positioning device 3 includes a plurality of positioning pins 31. One positioning pin 31 corresponds to one grinding block 2. The positioning pin 31 is threadedly connected to the end face of the base body 1 that supports the grinding block 2. The positioning pin 31 is designed as a cylindrical component with an external thread. A plurality of internal threaded holes matching the positioning pins 31 are provided on one end face of the base body 1 for fixing the positioning pins 31. The threadedly connected positioning pins 31 can provide very precise positioning, which helps to improve the processing accuracy of the grinding wheel.

[0042] In some embodiments, the positioning device includes a snap structure made of an elastic material. The snap can be embedded in the end face of the base body and has certain elasticity and self-locking function. The fixing part of the grinding block is designed in a shape with a slot, which can match the snap part of the positioning device. During assembly, align the fixing part of the grinding block with the snap part of the positioning device, and then press it in. Use the self-locking function of the elastic snap to fix it.

[0043] In this embodiment, the positioning device 3 further includes a magnetic attraction structure, which is used to magnetically attract the positioning device 3 and the grinding block 2. The magnetic attraction structure allows the grinding block 2 to be quickly attracted to the positioning pin 31, improving the positioning accuracy of the grinding block 2 and the assembly efficiency.

[0044] Please refer to Figure 4 , in this embodiment, the magnetic attraction structure includes a plurality of magnetic stickers 32. The magnetic stickers 32 that match each other are adhesively attached to the positions of the positioning pin 31 corresponding to the grinding block 2. One positioning pin 31 and one grinding block 2 are magnetically attracted by two magnetic stickers 32. Magnetic stickers 32 are respectively provided on the side surfaces (such as the upper side surfaces) of the positioning pin 31 and the module away from the base body 1. The position where the magnetic sticker 32 is provided on the positioning pin 31 can be on the outer periphery of its head. The two magnetic stickers 32 attract each other to form magnetic attraction, thereby firmly fixing the grinding block 2 on the positioning pin 31.

[0045] In this embodiment, a groove is provided on one end face of the base body 1, and the grinding block 2 is adhesively bonded in the groove. The design of the groove can ensure that the grinding block 2 can be stably installed therein. The positioning device 3 is also located in the groove and on one side of the grinding block 2 along the rotation direction of the base body 1. The positioning device 3 serves as a reference for the position of the grinding block 2. By contacting the grinding block 2, it can provide additional support when the grinding block 2 is subjected to centrifugal force, preventing the grinding block 2 from displacing.

[0046] In this embodiment, the grinding wheel further includes a sound-absorbing sheet, which is embedded in the base body 1. The base body 1 is designed to have a structure with an internal space or cavity, and these spaces or cavities can be used to embed the sound-absorbing sheet. The sound-absorbing sheet can be in the form of a sheet or other suitable form. The sound-absorbing sheet can be a thin sheet or filler made of sound-absorbing materials, which can absorb or attenuate noise.

[0047] Please refer to Figure 1 、 Figure 2 and Figure 5 , in this embodiment, the grinding wheel further includes a plurality of sound-absorbing lines 4 for absorbing and dispersing the noise generated during the grinding process. The plurality of sound-absorbing lines 4 are annularly arrayed on the end face of the base body 1 that supports the grinding block 2 and in the direction of the plurality of grinding blocks 2 close to the center of the base body 1. The center of the annular array of the plurality of sound-absorbing lines 4 is preferably the center of the base body 1. Preferably, there are at least four groups of sound-absorbing line groups, and each group of sound-absorbing line groups is provided with at least four arc-shaped sound-absorbing lines 4 arranged in sequence from the outside to the inside (close to the center of the base body 1 is the inside, and the shorter the arc length of the sound-absorbing line 4 is as it is closer to the inside). Figure 5 As shown in

[0048] Please refer to Figure 1 、 Figure 2 and Figure 5 , in this embodiment, the sound-absorbing line 4 is arc-shaped, and heat dissipation holes 5 are respectively provided at the head and tail thereof. These holes can be circular, elliptical or other suitable shapes to facilitate air circulation. The heat dissipation holes 5 have a heat dissipation function. During the cutting process, the aluminum base body 1 expands thermally due to heat, and the heat dissipation holes 5 also effectively relieve the thermal expansion deformation to keep the aluminum base body 1 of the grinding wheel flat.

[0049] Please refer to Figure 1 , in this embodiment, the base body 1 is provided with drain holes 6 penetrating through both end faces to facilitate the discharge of the grinding fluid and prevent accumulation. The drain holes 6 can have different diameters and quantities and are designed according to actual needs. The aperture size should be appropriate, ensuring sufficient drainage capacity while avoiding affecting the structural strength of the base body 1.

[0050] Please refer to Figure 1, in this embodiment, a slot hole 11 penetrating both end faces is provided at the center of the base body 1. The slot hole 11 is used to connect a rotating mechanism, such as the rotating shaft of a motor, to ensure that the grinding wheel can be stably connected to the driving device and obtain rotational power.

[0051] Please refer to Figure 1 , in this embodiment, an aluminum base body 1 can be selected. The aluminum base body 1 is light in weight per unit volume and has a small centrifugal force, which is beneficial to reducing the burden on the main shaft and is better and lighter for grinding silicon rods.

[0052] Please refer to Figure 1 , in this embodiment, a diamond grinding block 2 can be selected. It is mainly made of synthetic diamond, such as 300-mesh copper-tin alloy powder, and uses nano tungsten powder as a binder in a 2:1 mixing ratio and is sintered under high temperature and high pressure. It has better toughness and impact resistance and is also more environmentally friendly.

[0053] This application has the following beneficial effects:

[0054] 1. Through the setting of positioning pins and magnetic stickers, accurate positioning of the grinding block is achieved, improving the processing quality.

[0055] 2. The combined use of sound-absorbing lines, drain holes and sound-absorbing sheets effectively reduces the working noise during grinding and realizes the timely discharge of grinding fluid.

[0056] 3. The structure of this application is ingenious and easy to implement, improving the overall efficiency and quality of grinding processing.

[0057] It should be noted that although the above embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby.
