As shown in fig. 1-3, an abrasive brush comprises a base 1, the base 1 is cylindrical, the bottom surface of the base 1 is a plane, and a ring of enclosing plate 2 is arranged at the edge of the bottom surface, in this embodiment, the enclosing plate 2 and the base 1 are integrally formed for convenience of manufacturing and processing. The bottom surface of the base 1 is also provided with a plurality of brush silk bundles 3 which are uniformly distributed, and the brush silk bundles 3 are formed by densely distributing a plurality of brush silk; specifically, the brush filament bundle 3 may be installed on the base 1 by drilling and flocking, or may be fixed on the base 1 by injection molding.
Two brush tow retaining sheets 4 are arranged below the base 1, the two brush tow retaining sheets 4 are distributed in an up-down laminated manner, and through holes 5 for the brush tows 3 to pass through are formed in the brush tow retaining sheets 4; meanwhile, the brush tow retaining pieces 4 are all provided with sliding blocks 6, and correspondingly, the inner side walls of the enclosing plates 2 are provided with sliding grooves (not shown in the figure) matched with the sliding blocks 6, and the sliding grooves are perpendicular to the bottom surface of the base 1.
In this embodiment, the bristle-bundle holding pieces 4 are circular, and the size of the circular bristle-bundle holding pieces is equivalent to the area of the circle surrounded by the surrounding plate 2, the above-mentioned sliding blocks 6 are installed at the edges of the bristle-bundle holding pieces 4, and each bristle-bundle holding piece 4 is installed with a plurality of the above-mentioned sliding blocks 6, for example, 4, and the 4 sliding blocks 6 are evenly distributed on the edges of the bristle-bundle holding pieces 4 in the circumferential direction. In this embodiment, there are also 4 sliding grooves on the inner side wall of the enclosing plate 2.
The structure enables the brush silk bundle holding piece 4 to adjust the position thereof through sliding, so that the brush silk bundle 3 is restrained through the through hole 5 arranged on the brush silk bundle holding piece, the brush silk bundle 3 keeps a linear shape when in use, and the phenomenon that the end part cannot be ground due to bending is prevented; however, in the above-described structural design, the brush filament bundle holding piece 4 also needs a mechanism capable of facilitating the sliding thereof and fixing the position thereof.
In order to improve the above structural design, in this embodiment, the brush filament bundle holding pieces 4 are provided with nuts 7, the nuts 7 are provided with driving screws 8 used in cooperation therewith, the driving screws 8 are rotatably connected to the base 1, and the driving screws 8 are parallel to the above sliding grooves. By rotating the transmission screw 8, the purpose of driving the brush wire bundle holding piece 4 to slide can be realized, and the function of fixing the brush wire bundle holding piece at any position can be realized.
In the implementation of the rotatable connection between the transmission screw 8 and the base 1, the transmission screw 8 is provided with a bearing 13, correspondingly, the base 1 is provided with a bearing mounting hole (not shown) adapted to the bearing 13, and the transmission screw 8 rotates relative to the base 1 through the bearing 13.
In this embodiment, since the bristle-tuft retention pieces 4 are arranged in two layers, one of the drive screws 8 (the upper portion of the drive screw 8 for driving the bristle-tuft retention piece 4 located at the lower layer) is blocked by the one of the bristle-tuft retention pieces 4 located at the upper layer from being connected to the base 2, and the bristle-tuft retention piece 4 located at the upper layer is provided with the through hole 9 through which the drive screw 8 passes. Furthermore, the lower bristle holding piece 4 is also provided with the above-mentioned through hole 9 for passing another drive screw 8 (the lower portion of the drive screw 8 for driving the upper bristle holding piece 4).
The two brush tow retaining pieces 4 are arranged, so that the two brush tow retaining pieces 4 can be distributed at intervals when the brush tow retaining device is used, and the interval distance is preferably increased along with the distance of the two brush tow retaining pieces 4 from the base 1; therefore, in the present embodiment, it is provided that the first gear 10 and the screw handle 12 are mounted on the drive screw 8 for driving the brush filament bundle holding piece 4 located at the lower layer, and the second gear 11 is mounted on the drive screw 8 for driving the brush filament bundle holding piece 4 located at the upper layer. The first gear 10 is meshed with the second gear 11, and the diameter of the first gear 10 is half of that of the second gear 11 (i.e. the number of teeth of the first gear 10 is half of that of the second gear 11); for the convenience of operation, the upper portion of the driving screw 8 for driving the lower bundle holding piece 4 penetrates the top surface of the base 1, and the handle 12 is installed on the upper portion of the driving screw 8 so as to hold the handle 12 on the top surface side of the base 1.
The above-mentioned restriction of the gears is such that, by turning the screw handle 12, the drive screw 8 on which the first gear 10 is located is turned one turn, while the drive screw 8 on which the second gear 11 is located is turned only one half turn, as represented on the bristle holder pieces 4, it can be seen that the distance by which the bristle holder pieces 4 located on the lower layer are lowered or raised is twice the distance by which the bristle holder pieces 4 located on the upper layer are lowered or raised. So that the interval distance between the two bristle tuft holding pieces 4 increases as the two bristle tuft holding pieces 4 are spaced apart from the base 1, or, the interval distance between the two bristle tuft holding pieces 4 decreases as the two bristle tuft holding pieces 4 approach the base 1; in order to facilitate the use, the invention is provided that when the interval between the two bristle bundle retaining pieces 4 is zero, the two bristle bundle retaining pieces 4 are in the position of being attached to the bottom surface of the base 1.
When the brush holder is used, according to the grinding requirement (namely the length of the unconstrained brush wires), the position of the brush wire bundle retaining sheet 4 positioned at the lower layer is adjusted by rotating the screwing handle 12 (the position of the brush wire bundle retaining sheet determines the length of the unconstrained brush wires), and meanwhile, due to the existence of the first gear 10 and the second gear 11, the brush wire bundle retaining sheet 4 positioned at the upper layer is always positioned at the middle position of the constrained brush wires, so that the constrained part of the brush wires is stressed more uniformly, and the constraint and protection effects of the brush wires are close to or even equal to those of a sleeve in the traditional technology. Compared with the application of the sleeve in the prior art, the grinding brush is more convenient in structure and installation, and is beneficial to improving the manufacturing and production efficiency of the grinding brush.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
