DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0019] The utility model discloses an easy-to-grind diamond grinding wheel which is mainly used to generate a large amount of heat during the working process. The heat will cause the binder in the diamond grinding wheel to decompose or even carbonize. The large amount of heat generated by the diamond grinding wheel will also burn the surface of the workpiece being processed, causing tiny cracks, which greatly reduces the processing quality and makes it inconvenient for the diamond grinding wheel to perform long-term grinding, greatly affecting the processing efficiency.

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A diamond grinding wheel that is easy to grind includes a base 1, which is bowl-shaped. A lower surface 2 extending outward is arranged at the bottom of the surface of the base 1. A plurality of limiting holes 3 are opened at the top of the lower surface 2. A plurality of diamond grinding blocks 4 are arranged at the bottom of the lower surface 2. Two heat dissipation fins 5 are fixedly connected to the top of the diamond grinding block 4. The size of the heat dissipation fins 5 is consistent with the size of the limiting holes 3. A protective cover 6 is arranged at the top of the base 1. A spray piece 7 is fixedly connected to the inner wall of the protective cover 6. A plurality of spray ports are opened at the bottom of the spray piece 7. The spray piece 7 is connected to an external device through a pipeline.

[0021] In this solution, the diamond grinding block 4 can be positioned by setting the limit hole 3, and the heat dissipation performance of the diamond grinding wheel can be effectively improved by setting the heat dissipation fins 5 and the spray part 7, so that the diamond grinding wheel can be ground for a longer time, greatly improving the processing efficiency and quality. The protective cover 6 can prevent the sparks generated by the diamond grinding block 4 during grinding from flying.

[0022] Among them, a chip groove 11 is arranged between the diamond grinding blocks 4, and a plurality of air holes 12 distributed in a circle are opened on the side wall of the base 1. The air holes 12 are circular, and the protective cover 6 is semicircular. The protective cover 6 is made of polycarbonate. By setting the air holes 12, not only the heat dissipation performance of the diamond grinding block 4 can be further enhanced, but also the weight of the diamond grinding wheel is reduced, which is convenient for transporting the diamond grinding wheel. By setting the chip groove 11, the ground debris can be cleaned, so that a small part of the heat generated when the diamond grinding wheel is working can be discharged together with the ground debris. The protective cover 6 is semicircular, which is convenient for disassembly and assembly of parts in the protective cover 6. The protective cover 6 is made of polycarbonate so that it has good heat resistance and corrosion resistance.

[0023] Reference Figure 2 In a preferred embodiment, a first locking hole 8 is opened at the top of the lower surface 2, a second locking hole 9 is opened at the top of the diamond grinding block 4, the inner wall of the first locking hole 8 is smooth, the inner wall of the second locking hole 9 is provided with a thread, the inner thread of the second locking hole 9 is connected to a locking bolt 10, a mounting screw hole 13 is opened at the top of the base 1, and a mounting ring 14 is fixedly connected to the inner wall of the protective cover 6.

[0024] Specifically, first align the heat dissipation fin 5 at the top of the diamond grinding block 4 and insert it into the limiting hole 3 opened on the lower surface 2, then tighten the locking bolt 10 to make it pass through the first locking hole 8 and finally enter the second locking hole 9, thereby completing the installation of the diamond grinding block 4, and finally pass the equipment main shaft through the mounting ring 14 and finally enter the mounting screw hole 13 to connect the protective cover 6, the diamond grinding wheel and the main shaft together. The whole installation process is simple and convenient, which is convenient for repairing the diamond grinding wheel. The radius of the mounting ring 14 is larger than the radius of the mounting screw hole 13.

[0025] Among them, the mounting ring 14 is integrally formed with the protective cover 6, and the radius of the mounting ring 14 is larger than the radius of the mounting screw hole 13; the mounting ring 14 and the protective cover 6 are integrally formed to improve the firmness of the connection, and the radius of the mounting ring 14 is larger than the radius of the mounting screw hole 13 to prevent the protective cover 6 from rotating with the main shaft.

[0026] Furthermore, two lighting lamps 15 are fixedly connected to the top of the protective cover 6, which can be used for nighttime operation for easy viewing, and they share a set of power supply with the grinding wheel.

[0027] Working principle: When in use, the diamond grinding block 4 can be positioned when installed through the set limit hole 3. The diamond grinding block 4 can perform efficient heat exchange with the air through the heat dissipation fins 5 during daily use, effectively improving the heat dissipation performance of the diamond grinding wheel. During this process, the protective cover 6 can not only prevent the sparks generated by the diamond grinding block 4 during grinding from splashing toward the user, effectively improving the safety of the diamond grinding wheel, but also connect the spray part 7 located inside it with the external water source or coolant. The spray part 7 will continuously spray the heat dissipation fins 5 through the spray port located below it, further improving the heat dissipation performance of the diamond grinding wheel, allowing the diamond grinding wheel to be ground for a longer time, greatly improving the processing efficiency and quality.

[0028] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited to them. The replacement can be a replacement of part of the structure, device, method steps, or a complete technical solution. Equivalent replacement or changes based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
