DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] Refer to Figures 1 - 4, A metal diamond grinding wheel for quartz stone grinding, comprising a hub 1 and a mounting ring 4. The side surface of the hub 1 is penetrated with a mounting hole 2, and a keyway 3 is penetrated therein. Eight first threaded holes 15 are evenly arranged on the annular surface of the hub 1. First hexagon socket head cap screws 5 are threadedly connected in the eight first threaded holes 15. Eight counterbore holes 6 are evenly arranged on the annular side surface of the mounting ring 4. The inner diameters of the eight counterbore holes 6 are concentric with the inner diameters of the first threaded holes 15. The eight first hexagon socket head cap screws 5 are slidably connected in the counterbore holes 6. Through the threaded connection of the first hexagon socket head cap screws 5, the mounting ring 4 can be disassembled and assembled, which is convenient for replacement and prevents waste of resources. A spring 8 is slidably connected on the first hexagon socket head cap screws 5. One end of the spring 8 is fixedly connected to the annular outer surface of the hub 1, and the other end of the spring 8 is fixedly connected to the annular inner surface of the mounting ring 4. A certain gap is left between the hub 1 and the mounting ring 4. By providing the spring 8, when the grinding wheel is collided by the quartz stone, through the cooperation of the spring and the first screw 5, the spring deforms on the first screw 5 to buffer it, thereby prolonging the service life of the diamond grinding wheel.

[0021] In the present utility model, a first diamond grinding wheel 9 is sleeved on the annular outer surface of the mounting ring 4, and a second diamond grinding wheel 10 is sleeved on the annular outer surface of the first diamond grinding wheel 9. Four connecting holes 12 are evenly penetrated through the connection part of the first diamond grinding wheel 9 and the second diamond grinding wheel 10. A first annular notch 11 is arranged on the annular outer surface of the first diamond grinding wheel 9, and a second annular notch 14 is arranged on the annular outer surface of the second diamond grinding wheel 10. The two annular notches are provided to allow chips to flow out through the annular notches during the grinding process, preventing blockage and reducing the chip removal ability. Four second threaded holes 7 are evenly penetrated through the annular surface of the mounting ring 4. The four second threaded holes 7 are concentric with the connecting holes 12. Second hexagon socket head cap screws 13 are threadedly connected in the second threaded holes 7. The second hexagon socket head cap screws 13 are slidably connected in the connecting holes 12. The outer diameters of the hub 1, the mounting ring 4, the first diamond grinding wheel 9, and the second diamond grinding wheel 10 are all concentrically installed. When the upper diamond grinding wheel needs to be trimmed, the upper diamond grinding wheel is removed through the second screw 13 for trimming, and then the lower diamond grinding wheel is used to continue working. By providing a double-layer diamond grinding wheel, the problem that the grinding wheel cannot work during the trimming period and thus affects the work efficiency is solved.

[0022] The functional principle of the present utility model can be elaborated through the following operation methods:

[0023] When the diamond grinding wheel on the upper layer needs to be dressed, the diamond grinding wheel on the upper layer is removed through the second stud 13 for dressing, and then the diamond grinding wheel on the lower layer is used to continue working. By setting a double-layer diamond grinding wheel, the problem that the grinding wheel cannot work during the dressing period and thus affects the working efficiency is solved. If the quartz stone and the diamond grinding wheel collide during the working process, the spring arranged between the hub 1 and the mounting ring 4 is used to reduce the impact force brought by the collision and prevent the wear of the diamond grinding wheel caused by the collision. The internal spring is used to buffer it, thereby prolonging the service life of the diamond grinding wheel.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
