[0015] 1.

[0016] 2. Through the settings of the rough grinding layer and the fine grinding layer, the rough grinding layer can quickly remove a large amount of material, trimming the shape and size of the workpiece. This not only improves the processing efficiency but also can quickly complete the preliminary processing work, saving time and cost. The rough grinding layer has a large cutting force and is suitable for rough machining of the workpiece. The fine grinding layer is used for fine machining the surface of the workpiece, improving the accuracy and surface quality of the workpiece, enhancing the finish and accuracy of the workpiece. The design of the fine grinding layer enables more precise removal of defects on the surface of the workpiece, meeting the high - requirement processing needs. Through the setting of the positioning block, the positioning block helps to accurately position and fix the grinding wheel, avoiding the situation of poor grinding effect caused by loosening or offset of the grinding wheel during the working process, and improving the convenience and safety of the installation operation.

Detailed Description of the Preferred Embodiments

[0022] 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. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a cymbal - shaped fiber - reinforced resin grinding wheel disc as shown in Figures 1-4 which includes a grinding wheel 7 and a cymbal - shaped fiber layer 1 provided on the front - surface of the grinding wheel 7;

[0024] An installation groove 4 is provided at the middle position of the grinding wheel 7, an installation shaft 9 is provided at the middle position of the back surface of the grinding wheel 7, a bush 5 is provided on the installation shaft 9, and an installation through - hole 2 is provided on the bush 5;

[0025] On the back of the grinding wheel 7, there is a heat dissipation inner plate 6. There are multiple heat dissipation fins 10 on the heat dissipation inner plate 6. At the middle position of the heat dissipation inner plate 6, there is a heat dissipation ring 11. An air passage 12 is provided between the heat dissipation ring 11 and the heat dissipation fins 10. There is a heat dissipation outer plate 8 on the heat dissipation fins 10.

[0026] In this embodiment, a cymbal-shaped fiber layer 1 is attached to the surface of the grinding wheel 7. This cymbal-shaped fiber resin grinding wheel disc is a special type of grinding wheel disc, and its shape presents a cymbal-like appearance. This grinding wheel disc is usually composed of a fiber resin substrate and a particle binder, and has a strong grinding force and a long service life. The design of the cymbal-shaped fiber layer 1 enables better control of the feed speed and grinding pressure during grinding, and at the same time can provide higher grinding efficiency and better surface quality. The usage method of this cymbal-shaped fiber resin grinding wheel disc is as follows: First, install the cymbal-shaped fiber layer 1 of the grinding wheel disc outward, align the installation through hole 2 on the bushing 5 with the installation rod on the portable grinder and insert it, and then fix the grinding wheel disc on the portable grinder by fixing means such as bolts. Finally, the worker can use the cymbal-shaped fiber resin grinding wheel disc on the portable grinder to grind an object.

[0027] As Figure 2 、 Figure 3 and Figure 4 shown, the heat dissipation inner plate 6 is fixedly connected to the grinding wheel 7. The heat dissipation inner plate 6, the heat dissipation outer plate 8, and the heat dissipation fins 10 are all made of metal materials with good thermal conductivity. The heat generated during the operation of the grinding wheel 7 can be transferred to the heat dissipation inner plate 6. The heat dissipation fins 10 are integrally connected to the heat dissipation inner plate 6, and the heat dissipation fins 10 are welded to the heat dissipation outer plate 8. The heat transferred from the grinding wheel 7 to the heat dissipation inner plate 6 is transferred to the heat dissipation outer plate 8 via the heat dissipation fins 10. The heat dissipation ring 11 is integrally connected to the heat dissipation inner plate 6, and the heat dissipation ring 11 is welded to the heat dissipation outer plate 8. The air passage 12 formed by the heat dissipation ring 11 and the heat dissipation fins 10 allows air to circulate between the heat dissipation inner plate 6 and the heat dissipation outer plate 8.

[0028] Preferably, through the settings of the inner heat dissipation plate 6, the outer heat dissipation plate 8, the heat dissipation fins 10, the heat dissipation ring 11, and the air channel 12, when a large amount of heat is generated during the grinding process of the grinding wheel 7, the inner heat dissipation plate 6 attached to the back surface of the grinding wheel 7 will conduct the heat on the grinding wheel 7 to the heat dissipation fins 10 and the outer heat dissipation plate 8. The outer heat dissipation plate 8 can dissipate heat quickly through contact with the external air. When the grinding wheel 7 rotates, air will enter the gap between the inner heat dissipation plate 6 and the outer heat dissipation plate 8 and flow between the inner heat dissipation plate 6 and the outer heat dissipation plate 8 through the air channel 12. Through the flow of air, the heat exchange between the inner heat dissipation plate 6, the heat dissipation ring 11, the heat dissipation fins 10 and the external air can be accelerated, helping the grinding wheel 7 to dissipate heat. The setting of this device can improve the heat dissipation efficiency of the grinding wheel during the working process, prevent the cup-shaped grinding wheel from overheating during continuous use, resulting in partial softening or deformation of the grinding wheel, and ensure the grinding effect of the grinding wheel.

[0029] As Figure 4 shown, the rough grinding layer 13 is arranged below the cup-shaped fiber layer 1. The rough grinding layer 13 is fixedly connected to the cup-shaped fiber layer 1. A fine grinding layer 15 is arranged below the rough grinding layer 13. The rough grinding layer 13 is fixedly connected to the fine grinding layer 15. A substrate 14 is arranged below the fine grinding layer 15. The substrate 14 is fixedly connected to the fine grinding layer 15. The inner heat dissipation plate 6 is fixedly connected to the substrate 14. The grinding wheel 7 is composed of the cup-shaped fiber layer 1, the rough grinding layer 13, the fine grinding layer 15, and the substrate 14. A plurality of positioning blocks 3 are arranged inside the mounting through hole 2 on the shaft sleeve 5. The positioning blocks 3 are integrally connected to the shaft sleeve 5. The grinding wheel 7 can be positioned and installed through the positioning blocks 3.

[0030] Preferably, through the settings of the rough grinding layer 13 and the fine grinding layer 15, the rough grinding layer 13 is mainly used to quickly remove a large amount of materials on the surface of the workpiece, quickly trim the shape and size of the workpiece. The rough grinding layer 13 has a large particle roughness and a coarser grain size, with a higher cutting force, which is suitable for preliminary processing of the workpiece and effectively improves the processing efficiency. The fine grinding layer 15 is usually located inside the grinding wheel, used for fine processing of the workpiece surface to improve the accuracy and surface quality of the workpiece. The fine grinding layer 15 has a smaller particle size and a finer grain size, with a smaller cutting force, which can more finely remove the defects on the surface of the workpiece and improve the smoothness and accuracy of the workpiece. Through the setting of the positioning blocks 3, when the shaft sleeve 5 is installed on the portable grinder, the positioning blocks 3 can play a role in positioning and fixing the grinding wheel 7, preventing the grinding wheel 7 from loosening or shifting during work due to insecure fixation, thereby affecting the grinding effect.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
