[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] A new type of granite polishing disc, such as Figure 1 , 2As shown in Figures 3, 4, 5, 6, and 7, the invention includes a substrate 9 on which polishing discs 10 are mounted. Mounting holes 8 are formed on the substrate 9. In this embodiment, the mounting holes 8 are stepped holes. The polishing discs 10 are fan-shaped, and several are provided, forming a circular disc. The polishing discs 10 are evenly distributed circumferentially. Dovetail sliders 11 are fixedly mounted on each polishing disc 10. Several dovetail grooves 12 are formed on the substrate 9, allowing the dovetail sliders 11 to engage with the dovetail grooves 12. A limiting mechanism is provided on the substrate 9 to prevent the dovetail sliders 11 from disengaging. This invention has a simple structure and ingenious design. By designing the polishing discs 10 as fan-shaped and providing several, forming a circular disc, when a polishing disc 10 wears out and needs replacement, only the corresponding fan-shaped polishing disc 10 needs to be replaced, eliminating the need for overall replacement. This reduces material consumption and maintenance costs, meets practical needs, and is suitable for widespread application. When using this utility model, the dovetail sliders 11 on several polishing discs 10 are inserted into the corresponding dovetail grooves 12. Then, the sliding of the dovetail sliders 11 is restricted by the limiting mechanism. Then, the substrate 9 is mounted on the output shaft of the polishing machine through the mounting hole 8 and clamped with a nut. The polishing machine drives the substrate 9 and the polishing discs 10 to rotate, thereby performing polishing. When it is necessary to replace one of the fan-shaped polishing discs 10, the restriction of the limiting mechanism is released, the dovetail sliders 11 on the corresponding polishing disc 10 are pulled out from the dovetail grooves 12, and then a new polishing disc 10 is installed.
[0017] Specifically, such as Figure 6 As shown, the limiting mechanism in this embodiment includes a retaining ring 20, which is fitted onto a base plate 9. The base plate 9 and the retaining ring 20 are coaxially arranged. Several grooves 21 are formed on the base plate 9. Slider blocks 23 are elastically connected to the grooves 21 by first springs 22. The sliders 23 are fixedly mounted on the retaining ring 20. One end of the first spring 22 is fixedly connected to the inner wall of the groove 21, and the other end of the first spring 22 is fixedly connected to the slider 23. Under the elastic force of the first spring 22, the slider 23 abuts against the top of the groove 21, so that the retaining ring 20 blocks the outer end of the dovetail slide groove 12, and the dovetail slider 11 cannot slide out of the dovetail slide groove 12. When it is necessary to remove the polishing sheet 10, the retaining ring 20 is pressed down, and the slider 23 slides down along the groove 21. The first spring 22 is compressed. When the top of the retaining ring 20 is lower than the bottom of the dovetail slide groove 12, the dovetail slider 11 can move out of the dovetail slide groove 12, and the polishing sheet 10 can be removed.
[0018] Specifically, such as Figure 7As shown, in this embodiment, a circular hole 30 is formed on the substrate 9. A second spring 31 elastically connects to the insertion rod 32 within the circular hole 30. One end of the second spring 31 is fixedly connected to the inner wall of the circular hole 30, and the other end is fixedly connected to the insertion rod 32. A slot 33 is formed on the retaining ring 20. When the substrate 9 rotates at high speed, the insertion rod 32 slides outward under centrifugal force and inserts into the slot 33, thereby further preventing the retaining ring 20 from moving downward. This avoids the retaining ring 20 moving and causing the dovetail slider 11 to disengage when the substrate 9 and retaining ring 20 rotate at high speed, increasing safety during use.
[0019] Furthermore, as shown in the figure, the outer periphery of the retaining ring 20 in this embodiment is provided with anti-slip texture, which is not shown in the figure. The anti-slip texture facilitates manual pressing of the retaining ring 20.
[0020] Furthermore, as shown in the figure, in this embodiment, the end of the insertion rod 32 furthest from the second spring 31 is spherical. This spherical end of the insertion rod 32 makes it easier to insert into the slot 33, preventing it from getting stuck.
[0021] Furthermore, as shown in the figure, a guide rod 60 is fixedly installed on the insertion rod 32 in this embodiment, and a guide groove 61 is formed on the inner wall of the circular hole 30. The guide rod 60 and the guide groove 61 are slidably engaged. Through the engagement of the guide rod 60 and the guide groove 61, the movement direction of the insertion rod 32 can be restricted, preventing the retaining ring 20 from shifting during pressing or resetting.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
