Technical Field

The invention belongs to the field of grinding wheels, and particularly relates to a novel grinding wheel block forming a working surface of a consolidation grinding disk.

Background

The grinding wheel has a wide position in the field of grinding processing as a cutter, the quality of a processed workpiece is determined by the structure and the preparation process of the grinding wheel, and the grinding wheel can be composed of two parts: a base body and a grinding wheel block. The base body is usually a metal disc-shaped part and is used for supporting and bonding a grinding wheel block to form a working surface; a certain number of grinding wheel blocks are spliced and adhered to the base body, and the grinding wheel blocks are in direct contact with a workpiece in grinding processing to finish the grinding processing.

The grinding disk is a grinding wheel family, the grinding wheel block of present constitution consolidation grinding disk working face, mostly regular polygon or cylindrical, all adopt resin bond to use on the base member, the bonding needs certain area, when the thickness of grinding wheel block is too big, the upset moment that frictional force between work piece and the grinding wheel block caused during the grinding is too big, peel off the grinding wheel block from the base member easily, cause the grinding disk inefficacy, no matter how the grinding wheel block of this kind of shape is arranged simultaneously, it is not very smooth and easy to grind the chip removal, thereby influence grinding quality.

Disclosure of Invention

Aiming at the defects, the invention provides a novel grinding wheel block forming a working surface of a consolidation grinding disk, wherein the grinding wheel block is a triangular-evolution grinding wheel block with a polygonal special-shaped structure or a herringbone structure.

Furthermore, the side line connecting two adjacent top ends of the grinding wheel block is an inwards concave smooth arc line and/or a straight line, and the radian of the inwards concave smooth arc line is an obtuse angle.

Further, the radian of the concave smooth arc line is 120 degrees.

Further, three top ends of the grinding wheel block are round corners or straight corners.

Further, three top ends of the grinding wheel block are round corners and/or acute angles.

Furthermore, the geometric center of the grinding wheel block is positioned on the center of a circle formed by the three top ends.

Furthermore, the grinding wheel block and the grinding disc base body are connected in a bonding mode through resin bonding glue.

Furthermore, the grinding wheel block is of a polygonal special-shaped structure, the grinding wheel block of the polygonal special-shaped structure is of a special-shaped quadrilateral structure formed by folding the base edge of an equilateral triangle inwards, and the geometric center of the grinding wheel block is located at the center of a circle formed by the three top ends.

Furthermore, the grinding wheel block and the grinding disc base body are connected in a bonding mode through resin bonding glue.

Compared with the prior art, the invention has the following beneficial effects:

(1) the novel grinding wheel block forming the working surface of the consolidation grinding disk reduces the self weight of the grinding wheel block by changing the shape, reduces the falling-off condition caused by overlarge thickness during grinding, prolongs the service life of the grinding disk, and simultaneously ensures that the chips can be more smoothly removed during grinding due to the special design of the grinding wheel block.

(2) According to the novel grinding wheel block forming the working surface of the consolidation grinding disk, gaps among the grinding wheel blocks are increased by arranging the grinding wheel blocks in a polygonal or herringbone shape with triangular evolution, abrasive dust is prevented from being accumulated, grinding efficiency is influenced, various use requirements can be met, the self weight is reduced compared with the grinding wheel blocks in original shapes such as a cylindrical shape, the thickness of the grinding wheel block can be increased under the condition that the same resin adhesive is used for adhesion, and therefore the service life is prolonged.

In summary, the special structure of the present invention has many advantages and practical values, and similar methods are not published or used in the similar products, so that the present invention is innovative, has a practical and useful effect, and has a plurality of enhanced effects compared with the prior art, thereby being more practical and having a wide industrial value.
