Description

[Detailed description of the invention] The present invention is made by polymerizing a large number of circularly molded abrasive sheets, and making the abrasive blade axle by strongly press-forming the side surfaces at an appropriate angle with respect to the axis of the rotating shaft. When using it,
By displacing the surface of each sheet in contact with the surface of the object to be polished one after another, the vertical streaks caused by the gaps between the overlapping surfaces of the polishing blade axles are eliminated, and the entire surface of the object to be polished is uniformly polished. This is what I did.

Generally speaking, abrasive blade axles made by polymerizing coated abrasive paper include those in which a large number of circular abrasive sheets with a mounting hole in the center are fitted onto a rotating shaft, superimposed, and then pressed and fixed from both sides by presser plates. However, in such a polymerized abrasive blade axle, there is a gap between the overlapping parts of each sheet, and since these are on the same circumferential surface of the surface of the object to be polished, vertical streaks due to polishing leakage occur in that area. There are drawbacks.

The present invention aims to eliminate such drawbacks and polish the entire surface uniformly by making the side surface of the polymer such as abrasive coated paper in the structure of the abrasive blade axle inclined with respect to the axis of the rotating shaft. In addition to shifting the phase of the gap and polishing three times evenly, the holding pieces on both sides for tilting the polishing polymer with respect to the axis are made of the same material, and the outer diameter is adjusted to the polishing weight. The polymer is molded to have the same diameter as the coalescence, so that the polymer can be dressed at the same time, and the polymer can be held correctly. A base material such as coated abrasive paper with abrasive grains 2-1 coated on its surface. This is formed into a circular shape and a hole 3 is provided in the center to fit the rotating shaft. .

As this base material, cloth, paper, fiber, etc. are generally used, but mesh-shaped materials, non-woven fabrics, etc. are also used.

Next, reference numeral 4 is a rotating shaft, the abrasive sheet is superimposed on the center of the rotating shaft, and screws 5, 5 for screwing the tightening pieces are provided on both sides of the rotating shaft.

Further, 6 is a holding plate, and as shown in FIG. 3, for example, a sheet of the same quality as the abrasive sheet is polymerized and hardened with resin, and the inner surface thereof is an inclined surface 7 having an appropriate angle α0 with respect to the axis.
Its outer surface 7' is shaped at a right angle, and its outer diameter Y is the same diameter as the outer diameter X of the inclined abrasive polymer, and a hole 8 into which the rotating shaft 4 is inserted is provided in the center. It is something.

Further, reference numeral 9 denotes a tightening piece that is screwed into a screw 5 provided on the rotating shaft 4.

To construct each member as described above, first fit an appropriate number of abrasive sheets onto the rotating shaft 4 as shown in FIG. Insert,
Finally, by screwing the clamping pieces 9, 9 onto the screw 5°5 of the rotating shaft 4 and tightening them strongly, the polymerized abrasive sheet is rotated following the inclined surface 7 of the holding plate 6, as shown in FIG. It is set to be inclined by α0 with respect to the axis of the shaft 4.

By performing the polishing work using the polishing blade axle configured in this way, the seams of each polishing sheet are successively shifted in phase with respect to the surface of the object to be polished, and then the next polishing sheet comes into contact with the seam. Vertical streaks caused by polishing leakage are sequentially erased, allowing uniform and smooth polishing work to be performed on the entire surface.

Moreover, on both sides of this abrasive sheet polymer are presser plates made of the same or similar abrasive sheet hardened with a relatively flexible and easy-to-shave adhesive such as resin, and molded to have the same outer diameter as the polymer. Since the pressure is set by 1, the main body can be held correctly and the dressing can be performed at the same time.

In addition, the structure is extremely simple, easy to manufacture, and can be provided at low cost, which has practical effects.
