【0003】
この種の砥石フランジ組立体の先行技術として、本出願人と同一出願人が先に出願した特願2000−167784、特願2000−167785、特願2000−215343がある。

本発明は、前記のような各砥石フランジ組立体をさらに改良することを課題としたものである。
【0005】
【課題を解決するための手段】
前記課題を達成するために、請求項1に係る発明は、筒状の外周曲面1aの回転軸に対して回転対称な複数の位置に縦方向の凹溝1bおよびその凹溝1bの中央部にネジ穴1cが設けられた砥石支持フランジ1と、この砥石支持フランジ1の筒状の外周曲面1aと同一曲面の内面2aを有し、中央部に外面2a′から内面2aに貫通するボルト貫通用の縦方向の長孔2bが穿設され、その長孔2bの上下位置の内面から直角方向に前記砥石支持フランジ1の凹溝1bに嵌合する位置決めピン2cが設けられた砥石ホルダー2と、この砥石ホルダー2の下面に接着固定した砥石チップ3とよりなり、この砥石ホルダー2の前記位置決めピン2cを前記砥石支持フランジ1の筒状の外周曲面1aに形成した縦方向の凹溝1bに嵌合するとともに、前記砥石ホルダー2に形成した縦方向の長孔2bに貫通させたボルト4を、前記砥石支持フランジ1の凹溝1bの中央部に形成したネジ穴1cに締め付けて構成した砥石フランジ組立体としたものである。
【0006】
また、請求項2に係る発明は、前記砥石ホルダー2の下面に砥石チップ3を複数個接着固定した砥石フランジ組立体としたものである。
また、請求項3に係る発明は、前記砥石ホルダー2の下面に異種の砥石チップ3を複数個接着固定した砥石フランジ組立体としたものである。
また、請求項4に係る発明は、前記砥石ホルダー2の上面にも砥石チップ3を予備に接着固定した砥石フランジ組立体としたものである。
【0007】
【発明の実施の形態】
以下、本発明の砥石フランジ組立体の実施の形態を図面を参照して詳細に説明する。
図1は砥石フランジ組立体の平面図、図2は図1のA−A線おける断面図、図3は砥石チップを接着固定した砥石ホルダーを内面側から見た斜視図である。
【0008】
請求項1に係る発明の砥石フランジ組立体の構成部材である砥石支持フランジ1は、例えば金属製の筒状の外周曲面1aの回転軸に対して回転対称な複数の位置に、縦方向の凹溝1bおよびその凹溝1bの中央部にネジ穴1cが設けられている。なお、砥石支持フランジ1の上面中央に、この砥石支持フランジ1が平面研削盤や平面研磨盤の回転軸(図示しない)に取り付けられる取付孔1dが穿設されている。
【0009】
また、砥石フランジ組立体の構成部材である砥石ホルダー2は、図3に詳細に示すように、例えば金属製で、前記砥石支持フランジ1の筒状の外周曲面1aと同一曲面の内面2aを有し、中央部に外面2a′から内面2aに貫通するボルト貫通用の縦方向の長孔2bが穿設され、その長孔の上下位置の内面から直角方向に前記砥石支持フランジ1の凹溝1bに嵌合する位置決めピン2c,2cが設けられている。
【0010】
前記のように形成された砥石ホルダー2の下面に、例えば炭化珪素、窒化ボロン、ダイヤモンド等の砥粒をバインダを添加して長方形に形成した砥石チップ3が接着固定されている。なお、前記砥石チップ3は長方形に限定されるものでは無く、砥石ホルダー2の下面と同様な曲面に形成されたものであってもよい。
【0011】
前記のように形成された砥石支持フランジ1の外周曲面1aに、下面に砥石チップ3を接着固定した砥石ホルダー2を取り付けるには、この砥石ホルダー2の内面に設けた位置決めピン2c,2cを、前記砥石支持フランジ1の外周曲面1aに形成した縦方向の凹溝1bに嵌合するとともに、砥石ホルダー2の中央部に形成したボルト貫通用の縦方向の長孔2bに貫通させたボルト4を、前記凹溝1bの中央部に形成したネジ穴1cに締め付けて砥石フランジ組立体を組立構成したものである。前記ボルト4の頭には、図示していないが、6角凹穴が形成されたり、ボルト4の頭を6角形に形成している。
【0012】
このような構成としたことにより、砥石フランジ組立体の構成部材の点数および組立工数が少なくなり、製造コストを安くすることができる。また、前記砥石ホルダー2の内面2aに設けた位置決めピン2c,2cを、前記砥石支持フランジ1の外周曲面1aに形成した縦方向の凹溝1bに嵌合することにより、前記砥石ホルダー2に回転方向の大きな応力が掛かっても、砥石ホルダー2の取り付けが狂うことがない。また、砥石ホルダー2の中央部に形成したボルト貫通用の縦方向の長孔2bに貫通させたボルト4を、前記凹溝1bの中央部に形成したネジ穴1cに締め付ける構成にすることにより、各砥石ホルダー2の下面に接着固定した砥石チップ3の下面が被研磨ワークに正確に当接するように、各砥石ホルダー2を前記砥石支持フランジ1の外周曲面1aに取り付けることが簡単になる。また、前記砥石ホルダー2の横幅を、図1に示すように、これらの砥石ホルダー2を前記砥石支持フランジ1の外周曲面1aに取り付けたときに、円形に接合されるように設定することにより、前記砥石ホルダー2の取り付け狂いがさらに無くなる。
【0013】
図4は本発明の他の実施の形態の砥石フランジ組立体の構成部材である、砥石チップ3を接着固定した砥石ホルダー2を示す斜視図であり、(a)図は前記砥石ホルダー2の上面にも1個の砥石チップ3を予備に接着固定したものであり、(b)図は前記砥石ホルダー2の上面にも数個(この図においては同種または異種の2個)の砥石チップ3を予備に接着固定したものである。このようにすることにより、一方の砥石チップ3が摩滅すると、砥石ホルダー2を上下反転させて取り付け変えて使用することができる。
【0014】
【発明の効果】
請求項1に係る発明は、前記のように構成としたことにより、砥石フランジ組立体の構成部材の点数および組立工数が少なくなり、製造コストを安くすることができる。
また、前記砥石ホルダーの内面に設けた位置決めピンを、前記砥石支持フランジの外周曲面に形成した縦方向の凹溝に嵌合することにより、前記砥石ホルダーに回転方向の大きな応力が掛かっても、砥石ホルダーの取り付けが狂うことがない。
また、砥石ホルダーの中央部に形成したボルト貫通用の縦方向の長孔に貫通させたボルトを、前記凹溝の中央部に形成したネジ穴に締め付ける構成にすることにより、各砥石ホルダーの下面に接着固定した砥石チップの下面が被研磨ワークに正確に当接するように調整して、各砥石ホルダーを前記砥石支持フランジの外周曲面に取り付けることが簡単になる。
【0015】
また、請求項2または請求項3に係る発明のように、砥石フランジ組立体の構成部材である砥石ホルダーの下面に複数個の砥石チップを接着固定することにより、砥石チップのワークとの当接面積を広くして、作業効率を良くすることができる。
また、砥石ホルダーの下面に、砥粒の硬さや粒径の異なる異種の砥石チップを複数個接着固定することにより、ワークの粗研削から仕上げ研削までを効率良く行うことができる。
【0016】
また、請求項4に係る発明のように、前記砥石ホルダーの上面にも1個または複数個の砥石チップを予備に接着固定することにより、一方の砥石チップが摩滅すると、砥石ホルダーを上下反転させて取り付け変えて使用することができる。

A longitudinal slot 2b for bolt penetration penetrating from the outer surface 2a 'to the inner surface 2a is formed in the center portion, and the groove 1b of the grinding wheel support flange 1 is perpendicular to the inner surface of the elongated hole at a vertical position. Are provided with positioning pins 2c, 2c to be fitted to the boss.
[0010]
On the lower surface of the grinding wheel holder 2 formed as described above, a grinding wheel chip 3 formed by adding a binder such as silicon carbide, boron nitride, diamond or the like to a rectangular shape by adding a binder is bonded and fixed. The grinding wheel tip 3 is not limited to a rectangular shape, and may be formed on a curved surface similar to the lower surface of the grinding wheel holder 2.
[0011]
To attach the grindstone holder 2 having the grindstone tip 3 adhered and fixed to the lower surface to the outer peripheral curved surface 1a of the grindstone support flange 1 formed as described above, the positioning pins 2c, 2c provided on the inner surface of the grindstone holder 2 are attached. A bolt 4 fitted in a longitudinal concave groove 1b formed in an outer peripheral curved surface 1a of the grinding wheel support flange 1 and passed through a longitudinal long hole 2b for bolt penetration formed in a central portion of the grinding wheel holder 2 is provided. The whetstone flange assembly is assembled by tightening the screw holes 1c formed in the center of the concave groove 1b. Although not shown, a hexagonal concave hole is formed in the head of the bolt 4, or the head of the bolt 4 is formed in a hexagonal shape.
[0012]
With this configuration, the number of components and the number of assembly steps of the grinding wheel flange assembly are reduced, and the manufacturing cost can be reduced. In addition, the positioning pins 2c, 2c provided on the inner surface 2a of the grinding wheel holder 2 are fitted into the vertical concave grooves 1b formed on the outer peripheral curved surface 1a of the grinding wheel support flange 1, thereby rotating the grinding wheel holder 2.
