Description

Technical Field

[0001] The utility model relates to an industrial brush, in particular to a diamond industrial brush used for polishing and thinning hard and brittle materials, belonging to the technical field of industrial brushes. Background Art

[0002] For grooves, flat surfaces or curved edges of products made of hard and brittle materials such as sapphire, ceramics, and glass, diamond brushes are needed for polishing and grinding. Diamond brushes are a very common product. As an efficient, durable, and high-quality abrasive tool, diamond brushes have unparalleled advantages over other abrasive tools in polishing. They have the functions of polishing, cleaning, and thinning. Compared with ordinary brush wires, their higher hardness makes them very wear-resistant during grinding.

[0003] As for the prior art, a high-strength diamond brush disclosed in announcement number CN220074350U includes a brush plate, a plurality of plug-in slots are provided at the bottom of the brush plate, plug-in blocks are plugged into the plug-in slots, and a plurality of diamond brush wires are fixedly connected to the bottom end of the plug-in block; the plug-in block is used in conjunction with the plug-in slot, so that the diamond brush wires fixed to the plug-in block can be replaced, and then when the local diamond brush wires are damaged, the damaged area can be replaced conveniently. However, in actual use, the existing diamond brush adopts a plurality of diamond brush wires arranged on the brush plate, which can be used for flat surfaces or arc edges. It can perform better polishing and grinding treatment, but for the groove parts of some hard and brittle material products, the brush disc often cannot penetrate into the bottom of the groove, so it is impossible to achieve better polishing and grinding treatment of the groove parts. Secondly, the existing technology uses a plug-in connection to fix the diamond brush wire, but the brush wire will rotate at high speed when polishing the product, which can easily make the diamond brush wire loose under the action of centrifugal force, resulting in the plug-in connection cannot achieve fixed connection of the diamond brush wire, and it is also easy to make the diamond brush wire deviate from the initial installation position, which will also have a certain impact on the actual polishing and grinding effect.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0022] like Figures 1 to 6 As shown, a diamond industrial brush for polishing and thinning hard and brittle materials comprises a sleeve 1, an industrial brush 2 and a fixing rod 3, wherein the industrial brush 2 is mounted at the front end of the sleeve 1, and the industrial brush 2 is fixedly assembled with the sleeve 1 through the fixing rod 3;

[0023] The industrial brush 2 comprises a plurality of brush filaments 22, wherein the brush filaments 22 are woven from nylon material and contain agglomerated diamond abrasives. Example

[0024] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0025] The sleeve 1 includes a sleeve installation section 11 and a sleeve clamping section 12, which are integrally connected and are stepped. When the industrial brush is used, the sleeve clamping section 12 with a small diameter can be clamped and fixed to the clamping end of the driving setting. Since the connection between the sleeve installation section 11 and the sleeve clamping section 12 has a stepped surface, the clamping length of the sleeve 1 can be accurately controlled, thereby ensuring the firmness of the clamping part.

[0026] An installation cavity 15 and a tapered hole 14 are provided in the sleeve installation section 11. The inner end of the installation cavity 15 is connected to the tapered hole 14. One end of the threaded hole 13 is connected to the installation cavity 15. The other end of the threaded hole 13 extends into the sleeve clamping section 12. When the industrial brush 2 is fixed by the fixing rod 3, the fixing rod 3 can be deeply connected to the sleeve clamping section 12, that is, a deeper connection hole is provided to ensure that the industrial brush 2 is not easily loosened during use after connection.

[0027] The industrial brush 2 also includes a base plate 21 which is in a circular ring shape, and the tail ends of a plurality of brush filaments 22 are fixedly connected to the base plate 21 so that the plurality of brush filaments 22 can be combined through the base plate 21, thereby facilitating the installation of the plurality of brush filaments 22 on the sleeve 1. Example

[0028] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0029] The fixing rod 3 includes a rotating rod section 31 and a threaded rod section 32. The rotating rod section 31 and the threaded rod section 32 are coaxially connected, and the threaded rod section 32 is screwed into the threaded hole 13 of the sleeve 1. The fixing rod 3 and the sleeve 1 can be assembled by threaded engagement, and the industrial brush 2 can be fixedly installed on the sleeve 1.

[0030] The front end of the rotating rod segment 31 is integrally connected with a rotating end head 34, the inner side surface of the rotating end head 34 is conical, and the outer side surface of the rotating end head 34 is provided with an inner hexagonal groove 35, which can be inserted into the inner hexagonal groove 35 through an external hexagonal wrench to drive the rotating rod segment 31 to rotate, thereby providing a screwing force to the threaded rod segment 32, and while fixing the industrial brush 2, the rotating end head 34 with a conical surface can expand the brush filaments 22 outward to increase the coverage area of ​​the industrial brush on the workpiece, and the brush filaments 22 are evenly distributed around the rotating end head 34, so that the industrial brush can ensure a more uniform polishing of the workpiece during use.

[0031] A conical hole 14 is connected between the threaded hole 13 opened in the sleeve 1 and the installation cavity 15, and a conical rod segment 33 is provided between the rotating rod segment 31 and the threaded rod segment 32 of the fixing rod 3. When the fixing rod 3 is screwed on the sleeve 1, the conical rod segment 33 is clamped on the conical hole 14 to limit the final position of the fixing rod 3, so that the amplitude of the outward diffusion of each brush filament 22 is the same, that is, the overall appearance of the prepared industrial brushes is not much different, so as to meet the standardized production and processing.

[0032] Working principle: The industrial brush 2 is placed in the installation cavity 15 provided in the sleeve installation section 11 to achieve a preliminary connection between the industrial brush 2 and the sleeve 1, and then the fixing rod 3 is installed. The fixing rod 3 and the sleeve 1 are assembled by means of a threaded engagement connection, so that the industrial brush 2 can be fixedly installed on the sleeve 1, and the rotating end 34 provided on the fixing rod 3 can expand the brush filaments 22 outward to increase the coverage area of ​​the workpiece by the industrial brush, and the brush filaments 22 are evenly distributed around the rotating end 34, so that the industrial brush can ensure a more uniform polishing of the workpiece during use.
