Abstract
Description
Technical Field
[0001] The utility model relates to the field of stone processing machinery, in particular to a grinding disc used on a grinding machine. Background Art
[0002] With the improvement of people's living standards, stone balls are often used in various gardening landscapes, such as rockery or gate posts. After the stone ball is cut, it usually needs to be polished to make its surface shiny. In traditional production, this kind of polishing is mainly done manually, with relatively low production efficiency and difficult to guarantee the polishing quality, especially the spherical curvature of the stone ball.
[0003] A Chinese invention patent (Announcement No.: CN104942676B) discloses a linkage grinding device for processing multiple circular stone balls at the same time, which helps to improve the production efficiency of grinding stone balls to a certain extent. However, the above-mentioned invention patent drives the rotating ball seat and the stone ball to rotate through a motor, so as to grind through multiple diamond cutter heads arranged on the front side of the arc-shaped grinding disc. When the stone is being ground, each diamond cutter head is relatively still, and there are gaps between the conventionally arranged diamond cutter heads on the market. This results in that when grinding, the surface of the stone ball has an annular dividing line that has not been polished by the diamond cutter head, which affects the aesthetics of the stone ball. At present, workers usually perform secondary manual grinding to solve the annular dividing line. This manual method is not only slow, inefficient, and has high labor costs, but also the quality of the processed circular stone balls is uneven.
[0004] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which resulted in this case. Utility Model Content

[0022] A grinding disc for a grinder, used for grinding and polishing a stone ball 1. It is worth noting that the specific structure of a grinder in this embodiment can adopt the Chinese invention patent (Announcement No.: CN104942676B) which discloses a linkage grinding device for processing multiple circular stone balls at the same time. This embodiment only improves the multiple diamond bits set on the arc-shaped grinding disc in the technical scheme of the above-mentioned device. The rest of the structure is the same or similar to the above-mentioned patent and will not be described in detail here. In this embodiment, the stone ball 1 is rotatably set on the workbench, and the surface of the stone ball 1 is ground and polished by the diamond bit 3 set on the arc-shaped grinding disc 2 of the grinder.
[0023] The utility model discloses a grinding sheet for a grinding machine, comprising a plurality of diamond bits 3 sequentially attached to the surface of a curved grinding disc 2 from top to bottom, wherein the curvature of the curved grinding disc 2 along the transverse section is matched with the curvature of each diamond bit 3 along the transverse section, so that each diamond bit 3 can be more closely attached to the curved grinding disc with no gap therebetween.
[0024] Furthermore, the diamond bit 3 is in a sheet or plate structure and is attached to the arc-shaped grinding disc 2. Specifically, the diamond bit 3 can be fixed by bolts, snaps or adhesives, as long as the two can be detachably connected. In this embodiment, when replacing, the diamond bit 3 can be removed and replaced separately without affecting the use of the arc-shaped grinding disc 2.
[0025] Furthermore, the diamond bit 3 includes a first side 31 and a second side 32, both of which are concave-convex wave-shaped, and the concave-convex wave-shaped is composed of a plurality of wave crests and wave troughs alternatingly, that is, the first side 31 includes a first wave crest 311 and a first wave trough 312, and the second side 32 includes a second wave crest 321 and a second wave trough 322, the second wave crest 321 is arranged opposite to the first wave crest 311, and the second wave trough 322 is arranged opposite to the first wave trough 312, and when the diamond bit 3 is unfolded, the width along the vertical direction is the same everywhere.
[0026] like Figure 2As shown, the height (i.e. Figure 2 The position of the middle line segment b) is located at the height (i.e. Figure 2 The first wave valley 312 of the first side wall 31 always falls between the two adjacent second wave peaks 321 of the second side edge 32, thereby avoiding the appearance of annular lines on the surface of the stone ball 1 during polishing, achieving a non-polished discontinuity on the surface of the stone ball 1, optimizing the product appearance, and improving the aesthetics of the stone ball 1.
[0027] Furthermore, the second side 32 of the upper diamond bit 3 completely overlaps with the first side 31 of the other lower diamond bit 3 and fits tightly, so that they are arranged on the arc-shaped grinding disc 2 by means of threads, snaps or bonding, and the diamond bits 3 are pressed against each other.
[0028] Furthermore, when the diamond bit 3 is unfolded, the cross section along the vertical direction is a parallelogram structure, and two adjacent diamond bits 3 can be stacked together, connected to each other and closed along the side. Specifically, the first side 31 and the second side 32 are both provided with overlapping bevels (first overlapping bevels 313 and second overlapping bevels 323), the bevel angle of the first overlapping bevel 313 is 45 degrees, and the bevel angle of the second overlapping bevel 323 is -45 degrees. The second overlapping bevel 323 can perfectly match the first overlapping bevel 313 of the adjacent diamond bit. After the diamond bit 3 and the arc-shaped grinding disc 2 are positioned and installed, they are fixed by bolts, and each diamond bit 3 and the arc-shaped grinding disc 2 are locked and not easy to swing or disengage, so as to achieve an overall stable effect.
[0029] Furthermore, the thickness of the diamond segment 3 is 2-10 mm.
[0030] The beneficial effects of the utility model are: by setting the concave-convex wavy diamond bits 3, the appearance of annular lines on the surface of the stone ball 1 during grinding is avoided; at the same time, each diamond bit 3 is connected to the arc grinding disc 2 by connecting bolts or bonding, and there is no need to frequently replace the arc grinding disc 2, and the cost is relatively low; in addition, the first side edge 31 and the second side edge 32 of the overlapping bevel are provided, so that two adjacent diamond bits 3 overlap each other, so that each diamond bit 3 and the arc grinding disc 2 are locked and not easy to swing or separate, and the overall stability effect is achieved. The utility model has a simple and reasonable structure, high strength, uniform force, easy installation, strong stability, and long service life.
[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
