Description

本発明は、ハンディタイプのグラインダーに使用する研磨ディスクに関するものである。   The present invention relates to an abrasive disc for use in a handheld grinder.

ハンディタイプのグラインダーは、モータを内蔵した本体の先部に、ネジ軸となっている回転軸を備え、当該回転軸に研磨ディスクやその他の回転砥石を装着するようにしているものである。   The hand-held type grinder is provided with a rotating shaft serving as a screw shaft at the tip of a main body incorporating a motor, and a polishing disk or other rotating grindstone is mounted on the rotating shaft.

研磨ディスクの具体的形状として、特開平９−１７４４４４号公報（特許文献１）には、中央部に回転工具本体の回転軸に取り付けるための取付孔を有する支持基盤の一方の面に、研磨部が設けられており、この研磨部は、研磨布の多数を傾斜させた状態で且つその一部を重合させた状態で放射状に配列して高圧力でプレスし、重合状態で前記基板に接着剤により接着されている研磨ディスクが開示されている。   As a specific shape of the polishing disk, Japanese Patent Application Laid-Open No. 9-174444 (Patent Document 1) discloses that a polishing portion is provided on one surface of a support base having an attachment hole for attachment to a rotating shaft of a rotary tool body at a central portion. The polishing part is arranged in a radial state in a state where a large number of polishing cloths are inclined and a part of the polishing cloth is polymerized, and is pressed with high pressure, and the adhesive is applied to the substrate in a polymerized state. Abrasive discs that are bonded together are disclosed.

また特開平１１−１９８７６号公報（特許文献２）には、中心に取付孔を設けた支持基盤の一面に、平織りガラス繊維を樹脂で固めて形成した弾性砥石基材を、中心を大きく開けたリング状にして接着した研磨ディスクが開示されている。   In JP-A-11-19876 (Patent Document 2), an elastic grindstone base material formed by solidifying a plain weave glass fiber with a resin on one surface of a support base provided with a mounting hole at the center has a large center. An abrasive disc bonded in a ring shape is disclosed.

また特開２００２−３６１２７号公報（特許文献３）には、前記の研磨布を傾斜重合した研磨部を、支持基盤の表裏に接着している研磨ディスクが開示されている。   Japanese Patent Laid-Open No. 2002-36127 (Patent Document 3) discloses a polishing disk in which a polishing portion obtained by gradient polymerization of the polishing cloth is bonded to the front and back of a support base.

特開平９−１７４４４４号公報。JP-A-9-174444. 特開平１１−１９８７６号公報。Japanese Patent Application Laid-Open No. 11-19876. 特開平２００２−３６１２７号公報。Japanese Patent Laid-Open No. 2002-36127.

前記の研磨ディスクの取り付け手段は、機体（回転工具本体）の回転軸に、座金体（受け部材）を装着し、そしてディスク支持基盤の取付孔を挿通して装着し、緊締ナットを回転軸に螺合して研磨ディスクを回転軸に固定するものであり、研磨部が磨耗するとディスク全体を取り替えるものである。   The means for attaching the abrasive disc is to attach a washer body (receiving member) to the rotating shaft of the machine body (rotating tool body), insert it through the mounting hole of the disc support base, and attach a tightening nut to the rotating shaft. The polishing disk is fixed to the rotating shaft by screwing, and the entire disk is replaced when the polishing portion is worn.

従って取り替え作業の煩雑さがあり、而も前記したとおり従前の研磨ディスクの研磨部は、研磨布の傾斜重合体や、平織りガラス繊維を樹脂で固めた部材を採用しており、金属面研磨などを前提としているもので、木材等の柔らかい対象物に対しては直ぐに目詰まりしたりして不都合であるし、且つ消耗品として高価であるという問題もある。   Therefore, the replacement work is complicated, and as described above, the polishing part of the conventional polishing disk employs a gradient polymer of polishing cloth or a member obtained by solidifying plain weave glass fiber with a resin, such as metal surface polishing. This is inconvenient for a soft object such as wood, which is immediately clogged, and is also expensive as a consumable item.

そこで本発明は、着脱自在とした回転軸装着体と研磨体とで構成した新規な研磨ディスクを提案したものである。   Accordingly, the present invention proposes a novel polishing disk composed of a rotary shaft mounting body and a polishing body that are detachable.

本発明に係る研磨ディスクは、適宜なクッション機能を備えたベース部の上部に、回転軸への装着螺孔を設け、下部底面に多数の鉤状小突起で形成された絡着面を設けた回転軸装着体と、背面を前記絡着面に絡着可能な布面で形成し、表面を、砥粒を付着させて形成したヤスリ面とした研磨体とで構成したことを特徴とするものである。   The polishing disk according to the present invention is provided with a mounting screw hole to the rotating shaft in the upper part of the base part having an appropriate cushion function, and provided with an entangled surface formed by a large number of hook-shaped small protrusions on the lower bottom surface. A rotating shaft mounting body and a polishing body having a back surface formed of a cloth surface that can be entangled with the entangled surface and a surface formed by attaching abrasive grains. It is.

而して市販されているハンディタイプの回転工具本体（機体）の回転軸（螺軸）に回転軸装着体を螺合装着し、回転軸装着体の絡着面に、研磨体を絡着固定し、機体を駆動すると、ヤスリ面での研磨加工作業が可能となるものであり、研磨体のヤスリ面が磨耗すると研磨体を剥がし、新しい研磨体と取り替えれば、再度研磨加工作業が可能となる。   Thus, the rotating shaft mounting body is screwed onto the rotating shaft (screw shaft) of a handy-type rotary tool body (machine body) that is commercially available, and the abrasive body is fixedly attached to the tangling surface of the rotating shaft mounting body. However, when the machine is driven, it is possible to perform polishing work on the file surface.If the file surface of the polishing body is worn, the polishing body is peeled off, and if it is replaced with a new one, polishing work can be performed again. Become.

本発明は以上の構成であり、座金体や緊締ナットを必要とせずに、回転軸装着体を機体の回転軸に装着するのみで機体に取り付けられ、取り付け作業自体が簡単であると共に、研磨部の磨耗においては研磨体を剥離して新規な研磨体を貼付（絡着）すれば良いもので、研磨部の取替えも容易になされるものである。   The present invention has the above-described configuration, and can be attached to the airframe simply by attaching the rotating shaft mounting body to the rotating shaft of the airframe without the need for a washer body or a tightening nut. In this wear, the polishing body can be peeled off and a new polishing body can be attached (entangled), and the polishing part can be easily replaced.

次に本発明の実施形態について説明する。実施形態に示した研磨ディスクは、回転軸装着体Ａと研磨体Ｂとで構成されているものである。   Next, an embodiment of the present invention will be described. The polishing disk shown in the embodiment is composed of a rotating shaft mounting body A and a polishing body B.

回転軸装着体Ａは、装着部１と、ベース部２と、絡着部３を積層一体化したもので、装着部１は、上端中心に装着螺孔１１を備えたナット部１２を突出保持すると共に、ナット部１２の対向面を露出させて工具受け面１３として、且つ下方部分を円板形状に一体成形で製出したものである。ベース部２は、装着部１の底面に接着したもので、所定の厚みを有せしめた発泡樹脂で形成して、適宜なクッション性を備えさせたものである。また絡着部３は、マジックテープ（登録商標）のような多数の鉤状小突起を設けた薄板状で、前記ベース部２の底面に接着固定してなるものである。   The rotary shaft mounting body A is an integrated stacking unit 1, base unit 2, and entangled unit 3, and the mounting unit 1 projects and holds a nut portion 12 having a mounting screw hole 11 at the center of the upper end. At the same time, the opposing surface of the nut portion 12 is exposed to form a tool receiving surface 13 and the lower portion is produced in a disk shape by integral molding. The base portion 2 is bonded to the bottom surface of the mounting portion 1 and is formed of a foamed resin having a predetermined thickness so as to have appropriate cushioning properties. The entangled portion 3 is a thin plate provided with a number of hook-shaped small protrusions such as Velcro (registered trademark), and is bonded and fixed to the bottom surface of the base portion 2.

研磨体Ｂは、所謂サンドペーパー状のもので、背面を前記絡着部３に絡着可能な布面４で形成し、表面を、砥粒を付着させて形成したヤスリ面５としたものである。   The abrasive body B has a so-called sandpaper-like shape, the back surface is formed of a cloth surface 4 that can be entangled with the entangled portion 3, and the surface is a filed surface 5 formed by adhering abrasive grains. is there.

而して市販されている既存のハンディタイプのグラインダー（回転工具：機体）Ｃのアタッチメントの一種として使用するものであるが、前記の機体Ｃは他の部材を使用する際の保護カバー６を備えているので、図３に例示するように保護カバー６を外し、回転軸７に回転軸装着体Ａを螺合装着する。   Thus, although it is used as a kind of attachment of an existing handheld grinder (rotary tool: machine body) C that is commercially available, the machine body C has a protective cover 6 when other members are used. Therefore, as illustrated in FIG. 3, the protective cover 6 is removed, and the rotary shaft mounting body A is screwed to the rotary shaft 7.

そして次に研磨体Ｂを、前記回転軸装着体Ａの絡着面（絡着部）に貼り付ける（絡着）ことで固定されるので、図５に例示するとおり、回転工具を駆動すると、研磨体Ｂのヤスリ面での研磨加工作業が可能となるものである。そして研磨体Ｂのヤスリ面が磨耗したり目詰まりを起こすと、使用済みの研磨体を剥がし、新しい研磨体と取り替えれば 、再度研磨加工作業が可能となるものである。   And then, because the polishing body B is fixed by being attached (entangled) to the entangled surface (entangled portion) of the rotary shaft mounting body A, as illustrated in FIG. Polishing work on the file surface of the polishing body B is possible. When the file surface of the polishing body B is worn or clogged, the used polishing body is peeled off and replaced with a new polishing body, so that the polishing work can be performed again.
