Description

Technical Field

[0001] The utility model belongs to the technical field of diamond brushes, in particular to a diamond industrial brush which is easy to replace. Background Art

[0002] Diamond industrial brushes, as the name suggests, are made with diamond as the primary abrasive or filament. Diamond, one of the hardest substances in nature, endows these brushes with exceptional hardness, wear resistance, and high-temperature resistance. These characteristics give diamond industrial brushes significant advantages in industrial applications such as cleaning, polishing, and grinding.

[0003] After searching, the Chinese patent with announcement number CN207548540U discloses a diamond disc brush for PCB grinding, which includes an aluminum alloy disc. A grinding disc is provided on the outer side of one end face of the aluminum alloy disc. The grinding disc includes a plurality of fan-shaped grinding units, each grinding unit including a fan-shaped diamond grinding block and a fan-shaped non-woven fabric block; adjacent grinding units are connected by fan-shaped elastic silicone blocks; a connection structure for installation and driving of an external drive device is provided at the center of the other end face of the aluminum alloy disc.

[0004] Although the diamond disc brush in the above-mentioned prior art can facilitate the replacement of diamond industrial brushes by adding a connecting key with a connecting hole, there are still some shortcomings in actual use. For example, the diamond grinding block is fixed on the aluminum alloy disc and cannot be disassembled. When the diamond grinding block needs to be replaced later, the entire aluminum alloy disc needs to be replaced together, and the replacement cost is high. Secondly, the aluminum alloy disc lacks a good heat dissipation structure. When the diamond disc brush is working, especially when performing high-speed or high-intensity operations, a large amount of frictional heat will be generated. The heat cannot be dissipated, and the high temperature will have a certain adverse effect on the physical properties of the diamond grinding block, such as reduced hardness, thermal expansion, etc., which will further affect its service life and processing effect.
