Description

Technical Field

[0001] The utility model relates to the technical field of diamond grinding wheels, in particular to a ceramic diamond grinding wheel for processing jewelry-grade high-temperature and high-pressure synthetic diamonds. Background Art

[0002] Diamond grinding wheel is a super-hard abrasive grinding wheel, mainly used for grinding difficult-to-process materials such as cemented carbide, glass, ceramics, etc. It is composed of diamond abrasive, binder (such as metal powder, resin powder, ceramics) and filler, and is divided into three parts: working layer (diamond layer), transition layer and matrix. Diamond grinding wheel has the characteristics of high hardness, low wear and strong wear resistance. It is suitable for high-precision processing and has high production efficiency.

[0003] During the high-temperature and high-pressure processing of synthetic diamonds, the grinding wheel will wear faster due to the high hardness of diamonds. On this basis, the common grinding wheel body and metal sheet are mainly fixed by adhesion, which makes it difficult to disassemble them independently. Therefore, when replacing the grinding wheel, the grinding wheel body and metal disc need to be replaced as a whole, which leads to higher overall consumables costs and increased processing costs.

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Example

[0019] like Figure 1-4 As shown, the utility model proposes a jewelry-grade ceramic diamond grinding wheel for high-temperature and high-pressure synthetic diamond processing, comprising a metal disc 1 and a grinding wheel body 2, an epitaxial plate 11 is fixed on the outer side of the metal disc 1, the grinding wheel body 2 is sleeved on the metal disc 1, and the rear side is against the epitaxial plate 11, a group of positioning columns 12 are fixed on the epitaxial plate 11, and the grinding wheel body 2 is provided with positioning holes 23 aligned with the positioning columns 12, a pair of fixing columns 13 are installed on the outer periphery of the front side of the metal disc 1, and fixing holes 24 corresponding to the fixing columns 13 are opened on the inner side wall of the grinding wheel body 2, heat sinks 3 are fixed on the back of the metal disc 1 and are distributed in a circle, a chamfer 21 is opened on the outer periphery of the front side of the grinding wheel body 2, a heat dissipation groove 22 is opened on the outer side wall of the grinding wheel body 2, wave patterns 31 are opened on both sides of the heat sink 3, and through holes 32 are evenly opened on the heat sink 3, and a shaft mounting hole 4 is opened at the center of the metal disc 1.

[0020] An installation frame 14 is fixed on the front side of the metal plate 1 and at a position corresponding to the fixed column 13. A telescopic block 16 is slidably connected inside the installation frame 14. One end of the outer side of the telescopic block 16 is fixedly connected to the end of the fixed column 13. A telescopic spring 15 is fixed between one end of the inner side of the telescopic block 16 and the inner wall of the telescopic groove. A pull plate 17 is slidably connected to the outer side of the installation frame 14. The pull plate 17 and the telescopic block 16 are fixed by a connecting block.

[0021] In this embodiment, the positioning hole 23 on the grinding wheel body 2 is first aligned with the positioning column 12 on the extension plate 11, and the grinding wheel body 2 is sleeved on the outer periphery of the metal disk 1 to ensure that the position of the fixing column 13 is aligned with the position of the fixing hole 24. Then, the fixing column 13 is inserted into the fixing hole 24 by the push of the telescopic spring 15, so that the grinding wheel body 2 and the metal disk 1 can be fixed. On this basis, for the disassembly of the grinding wheel body 2, it is only necessary to pull the pull plate 17, and when the telescopic spring 15 is compressed, the telescopic block 16 is driven to slide, so that the fixing column 13 can be pulled out of the fixing hole 24 for quick disassembly operation. When replacing, it is convenient to replace the grinding wheel body 2 independently, reduce consumables, and thus achieve the purpose of reducing processing costs. At the same time, when the grinding wheel body 2 rotates for processing, its heat sink 3 and heat dissipation groove 22 can increase the heat dissipation area of ​​the grinding wheel body 2 and the metal disk 1, thereby improving the heat dissipation effect.
