Finishing ω1 polishing, welding bead removal, and
This invention relates to the improvement of abrasive disks used for various operations (hereinafter collectively referred to as polishing operations, etc.) such as deburring, corner removal, base finishing before painting, rust removal, and paint (paint film) stripping.

・構成した砥材を利用する方法が用いられる。This tool has a disc-shaped polishing (grinding) member removably attached to the tip of a rotating shaft such as a motor built into the main body.Is this tool used for polishing flat surfaces and circumferential surfaces? Since the heat dissipation method is air-cooled, there are problems with heat and burnout when using it.
Aiming at improving the heat dissipation effect and increasing the manufacturing efficiency of the abrasive material, a method is used that uses an abrasive material in which a large number of small pieces of sandpaper are stacked and arranged in a U-shape.

3 is a built-in motor, 3 is a motor rotation shaft, and 4 is attached to the rotation shaft 3 so as to rotate integrally therewith and to be detachable (J).
A disc-shaped polishing member 5 is tightened to harden the polishing member 4 on the tip of the rotating shaft 3 overnight (=J member, 6
is a cover with a cutout opening for protecting the human body from the rotational movement of the polishing member 4.

ａの下方鏡面に固着されることになる。The polishing member 4 is composed of a base 4a and a large number of lead paper pieces 4b arranged in an annular manner on the mirror surface (end surface) in a μ-shape. In this case, each piece of paper 4b, each formed in the shape of a long and thin plate, is stacked diagonally on top of each other in such a manner that its free end is dragged against the clockwise rotation of the shaft 3.

It will be fixed to the lower mirror surface of a.

劣化さＵる原因となっていた。Therefore, in the polishing member having such a structure, the abrasive grains and grinding powder that have fallen off during the polishing operation tend to get into the spaces between the sandpaper pieces 4b, causing the so-called "clogging" phenomenon. The heat dissipation effect of the sandpaper is also poor, which, together with the softness peculiar to sandpaper pieces, causes a significant deterioration in polishing accuracy.
（発明が解決しようとする問題点）
しかし乍ら、Ｕ１磨作業においては「砥粒の剥落」及び
「研磨屑粉」の発生それ自体は不可避な事柄であるので
、このことを前提として設計される研磨工具という観点
から考えると、前述の欠点は、従来の研磨部材の構造が
、これら「砥粒の剥落」及び「研磨されて被加工物から
分離した屑粉」の処理に対して適切な構造になっていな
かったことに、その原因があったと考えざるを得ない。(Problem to be Solved by the Invention) However, in the U1 polishing operation, "abrasive grain flaking" and "abrasive dust" generation itself are unavoidable, so the design was designed with this in mind. From the perspective of a polishing tool, the above-mentioned drawback is that the structure of the conventional polishing member is not suitable for handling these ``abrasive grain flakes'' and ``dust particles separated from the workpiece after polishing.'' I can't help but think that the reason for this was the lack of structure.
本発明は、この事情に鑑みてなされたもので、「放熱効

生かし乍ら、これら「砥粒の剥落」及び「研磨屑粉」の
処理をも適切に行い賀る構造をもつ新規な研磨部材を提
供することを目的としている。The present invention has been made in view of this situation, and while taking advantage of the aspects of "improvement of heat dissipation effect" and "self-growth effect of the cut surface of the abrasive piece U1", it is The object of the present invention is to provide a new polishing member having a structure that can appropriately perform and complete the processing of ``.

るものと考えられる、。[Structure of the Invention] (Means and Effects for Solving the Problems) The reason why conventional polishing members cause clogging is that the sandpaper pieces formed in plate shapes are arranged at narrow intervals from each other. When the flaked abrasive grains and 4Jt abrasive powder caught between the workpiece and the polishing member during polishing enter between each piece of paper, even if it is centrifuged due to rotation) Even if you move, it becomes difficult to release from that spot,
Furthermore, it is thought that the fact that each piece of sandpaper is closely held together is what is accelerating this phenomenon.

The two side surfaces /IIG 41d that connect both surfaces are j-planes (j-planes) that approach downwards, respectively, so that the width L4 of the ω1 cutter 41a is narrower than the width Q of the push surface 41b. Alternatively, one of the surfaces is formed as an aperture surface. That is, the width uWa of the U1 cutter 11a is formed to have a wedge-shaped cross section smaller than the width Wb of the press surface/11b.

The wedge-shaped claws +; It is formed in an oil shape and an annular shape with respect to the motor shaft 3.The inner taper of the through groove 42a is set to the same value as the taper ω set on the side surfaces 41C and 41d of the wedge-shaped abrasive material piece.

With the part protruding from the lower mirror surface of the base 42, the side surfaces 41G and 41d of the abrasive material piece come into contact with the tapered inner surface of the through groove 42a and prevent the wedge-shaped abrasive material piece 41 from protruding further. be.

先ず、褐色溶融アルミナを用いて素材円盤を成形するが
、この段階にｄ３いて２種のものが考えられる。First, a material disk is formed using brown molten alumina, and at this stage, two types of materials can be considered.

。In the material circle U S ' S ' obtained in this way,
During machining, make cuts in the radial direction and in the direction perpendicular to it, and cut out the desired shape of the material. The dimensions of the material disk 5-8- shall be determined and placed.

The thickness is constant and only the sides are sloped, or ([[Fig. 1 (D
), both sides are sloped and there is also a taper in the thickness direction.
尚、索材円盤５−８−を成形する際に用いる成形型には

Since the tapered inner surface of the conveyance groove 42a that is in contact with the side surfaces 41G and 41d of the abrasive material piece is received, the abrasive material 11 itself is subjected to more than one unreasonable force, and in the middle of the ω11 operation. The flaked abrasive grains and polishing powder try to get between the wedge-shaped abrasive material pieces 41, but since there is no structure or anything to stop the flaked abrasive grains and polishing powder, these separated particles are Due to the centrifugal force accompanying the rotation of the polishing part support 40, it is forcibly moved in the radial direction.

The pressing of AY1 has been explained assuming that the width of the surface is constant (parallel), but if we consider arranging the abrasive material pieces in an annular shape, we can leave the old side taper as is and use the pressing in Fig. 2. However, it is more effective to configure the inner width of the rim 41b to be narrower than the outer width, that is, to form a shape that is longer and thinner. In this example, the deviation in the degree of wear that occurs outside the circumferential speed between the outer circumference and the inner circumference on the rotating grinding surface is defined as "the grinding surface of the wedge-shaped abrasive material on the outer circumference and the inner circumference." This has the advantage that it becomes possible to correct the area difference by adjusting the area difference.
また、楔形砥材片のテーパ付き側面を第１実施例のよう

るという利点を生じる。Furthermore, when the tapered side surface of the wedge-shaped abrasive material piece is selected as in the first embodiment, the thickness of the abrasive material piece can be increased in the direction of grinding movement, and the mechanical strength of the abrasive material piece can be increased. It gives rise to the advantage of being enhanced.
更に、基盤に対する楔形砥材片の固定方法は、適宜の接
着剤による接着固定法でもよい。Further, the wedge-shaped abrasive material piece may be fixed to the base by an adhesive fixing method using an appropriate adhesive.

Although we have described an example of a Y''C-configuration, it is not limited to this; for example, as shown in FIG.
Even if it is possible to manufacture a large number of solid abrasive material parts connected to each other by the integral molding method of A and take it into a disc, it is also possible to It may also be manufactured by integral molding.
