[0008] Furthermore, in the innermost layer of working teeth, two adjacent working teeth form a water inlet of the drainage groove, and the width of the water inlet of the drainage groove is from wide to narrow along the flow direction of the cooling water. In the outermost layer of working teeth, two adjacent working teeth form a drainage outlet of the drainage groove, and the width of the drainage outlet of the drainage groove is from narrow to wide along the flow direction of the cooling water.

[0009] Furthermore, the gap between two adjacent layers of the working teeth serves as a part of the drainage groove, and its width is smaller than the water inlet and the drainage outlet of the drainage groove.

[0041] See also Figures 1 to 6 This embodiment provides a grinding wheel, including a base 1 and working teeth 2, the working teeth 2 are arranged on the mounting plane 11 of the base 1, there are multiple working teeth 2, and the multiple working teeth 2 are arranged at intervals along the circumference of the base 1, and drainage grooves 21 are formed between adjacent working teeth 2. A recessed water storage tank 12 is provided on the mounting plane 11 of the base 1, and the water storage tank 12 is located on the inner side of the working teeth 2. The drainage port 14 of the water storage tank 12 extends to the water inlet 22 of the drainage tank 21, so that the drainage tank 21 receives cooling water from the water storage tank.

[0042] The water reservoir 12 collects cooling water from the cooling water pipe 3 to prevent excessive loss of cooling water. It is located inside the working teeth 2, closer to the center of the grinding wheel. The reservoir 12 has one or more drain ports 14 connected to the water inlet 22 of the drain trough 21, ensuring that cooling water can flow from the reservoir 12 to the drain trough 21.

[0043] As the grinding wheel rotates, the cooling water in the water reservoir 12 is pushed toward the drain ports 14 due to centrifugal force. Through these ports 14, it enters the drain trough 21. The cooling water is then directed to the grinding area, where it acts on the working teeth 2, helping to reduce the grinding temperature and remove grinding debris. This allows the cooling water to be more evenly distributed throughout the grinding area, improving cooling efficiency.

[0044] See also Figure 1 and Figure 2 In this embodiment, the water inlet 13 and drain outlet 14 of the water tank 12 are spaced apart on the mounting surface 11, with the drain outlet 14 located outside the water inlet 13. The portion of the water tank 12 between the water inlet 13 and the drain outlet 14 is not linear but curved, with this curved portion located below the mounting surface 11. After entering the water tank 12, the cooling water first flows downward for a distance, then moves outward through the curved portion, ultimately reaching the drain outlet 14 of the water tank 12.

[0045] See also Figure 3 and Figure 4 In this embodiment, a plurality of working teeth 2 are arranged in multiple layers inside and outside, and the working teeth 2 in each layer are arranged at intervals along the circumference of the base 1. Figure 3 As shown, the base 1 is provided with two layers of working teeth 2: an inner layer and an outer layer. Within the same circumference (the same layer), there is a certain spacing between the working teeth 2. Between different layers, the working teeth 2 are staggered. During the grinding process, cooling water can flow through these gaps, better covering the entire grinding area and ensuring sufficient cooling.

[0046] See also Figure 4In this embodiment, the width of the drain groove 21 varies to enhance the flow rate and pressure of the cooling water. The drain groove 21 is not uniform in width, but widens or narrows in certain areas as needed to control the flow rate and pressure of the cooling water.

[0047] See also Figure 4 In this embodiment, in the innermost working teeth 2, adjacent working teeth 2 form water inlets 22 of drainage grooves 21. The width of the water inlets 22 of the drainage grooves 21 gradually narrows along the direction of cooling water flow. When the grinding wheel rotates, cooling water first enters the water inlets 22 between the innermost working teeth 2. This water inlet 22 is designed to be wide to facilitate smooth cooling water entry. In the outermost working teeth 2, adjacent working teeth 2 form drainage openings 23 of the drainage grooves 21. The width of the drainage openings 23 of the drainage grooves 21 gradually narrows along the direction of cooling water flow. Figure 4 The arrows in the figure show the direction of cooling water flow. Appropriate water flow rate and pressure help to better remove the debris generated during the grinding process, reduce debris accumulation, and improve chip removal performance.

[0048] See also Figure 4 In this embodiment, the gap 24 (also called the circumferential channel) between two adjacent layers of working teeth 2 serves as a part of the drainage groove 21 ( Figure 4 This portion, shown extending along the circumference of the base body 1 (the working teeth 2 are arc-shaped), is narrower than the water inlet 22 and outlet 23 of the drainage groove 21. This creates a pressure differential and a higher flow rate. When the grinding wheel is operating, the cooling water flows through the drainage groove 21 under the action of centrifugal force, enhancing the cooling effect on the grinding contact surface.

[0049] See also Figure 4 In this embodiment, the width of the gap 24 between two adjacent layers of working teeth 2 is between 1 cm and 2 cm. The width of the water inlet 22 of the drainage groove 21 is between 4 cm and 5 cm. Since the width of the water inlet of the drainage groove 21 is gradually narrower, that is, the wide part can be 5 cm and the narrow part can be 4 cm. The width of the drainage outlet of the drainage groove 21 is between 4 cm and 5 cm. The width of the drainage outlet 23 of the drainage groove 21 is gradually widened, that is, the wide part can be 5 cm and the narrow part can be 4 cm.

[0050] The design of the drainage groove 21 increases the flow rate and pressure of the cooling water, further improving the cooling effect and chip removal performance of the grinding contact surface, avoiding abnormal grinding quality of the workpiece 4 caused by lack of water in a wide grinding contact area, and possible burns of the grinding wheel caused by heat.

[0051] See also Figure 3 and Figure 4In this embodiment, the number of water inlets 22 of the drainage trough 21 is the same as the number of drain outlets 14 of the water storage tank 12, and they correspond one to one. Each drain outlet 14 of the water storage tank 12 has a corresponding water inlet 22 of the drainage trough 21 to match it, thereby ensuring that the flow path of cooling water from the water storage tank 12 to the drainage trough 21 is clear and orderly, realizing centralized distribution and uniform spraying of cooling water, and improving the effective utilization rate of cooling water.

[0052] See also Figure 5 and Figure 6 In this embodiment, the workpiece 4 is ground by a grinding wheel. Generally, during grinding, the grinding wheel and the workpiece 4 are in relative motion. The grinding wheel can be fixed at one position and rotated circumferentially (the direction of rotation is as follows: Figure 6 As shown by the arrow m), the workpiece 4 is translated (the translation direction is as shown in FIG. Figure 6 as indicated by the arrow n).

[0053] See also Figures 1 to 6 This embodiment further provides a grinding device, comprising:

[0054] A grinding wheel, wherein the grinding wheel is the grinding wheel described in any one of the above embodiments;

[0055] a rotating mechanism connected to the side of the base 1 of the grinding wheel facing away from the mounting plane 11 and used for driving the grinding wheel to rotate; and

[0056] The cooling mechanism includes a cooling water pipe 3, which is located on one side of the grinding wheel. The water outlet of the cooling water pipe 3 extends into the water inlet of the water storage tank 12 of the grinding wheel.

[0057] The rotating mechanism is responsible for driving the grinding wheel to rotate at high speed. Typically, the rotating mechanism includes a motor and a transmission device (such as a gear or pulley). The motor provides power, which is transmitted to the base 1 of the grinding wheel through the transmission device, causing it to rotate at high speed, thereby performing the grinding operation.

[0058] The cooling mechanism's primary function is to provide the necessary cooling water for the grinding process, reducing the temperature in the grinding area and removing grinding debris. The cooling mechanism comprises a cooling water pipe 3, the outlet of which is designed to extend into the inlet of the grinding wheel water reservoir 12. This design ensures that cooling water enters the water reservoir 12 directly and efficiently, and is evenly distributed through the drain outlet of the water reservoir 12 to the drain trough 21, ultimately reaching the grinding area.

[0059] A water tank 12 is provided in the middle of the aluminum base 1 of the grinding wheel, and cooling water is collected in the water tank 12 through the cooling water pipe 3. The cooling water pipe 3 is located directly above the water tank 12, and the end of the cooling water pipe 3 can extend into the water tank 12, so that all the water flow is concentrated in the water tank 12 to prevent the loss of cooling water.

[0060] When the grinding wheel is working and grinding the surface of the silicon rod, in the working area, the cooling water is concentrated in the water storage tank 12, and is sprayed into the drainage groove 21 through the drain port by centrifugal force, ensuring that the cooling water is evenly brought to the grinding area. The water storage tank 12 prevents the water flow from being dispersed, and the cooling water is effectively utilized. A certain flow rate is formed by centrifugal force to improve the flushing effect. The cooling water enters through the water inlet (wider) of the drainage groove 21, and is driven by centrifugal force to flow through the circumferential drainage groove 21 (thinner), forming a pressure difference and a higher flow rate. The water is then discharged from the drain port of the drainage groove 21, which enhances the cooling effect of the grinding contact surface and the chip removal effect of the grinding chips. Such a structure is ingenious, easy to manufacture and maintain, and can be widely used in the field of grinding processing of hard and brittle materials such as silicon rods, with significant economic and social benefits.

[0061] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present utility model. Therefore, based on the innovative concept of the present utility model, changes and modifications to the embodiments described herein, or equivalent structural or process transformations made using the contents of the present utility model specification and drawings, and direct or indirect application of the above technical solutions to other related technical fields are all included in the scope of protection of the present utility model patent.
