Description

本発明は、加工面を研削するための研削砥石および研削装置に関する。   The present invention relates to a grinding wheel and a grinding apparatus for grinding a processed surface.

研削砥石としては、円板部材の側面の外周縁部に環状の砥石部材を突設させたものがある。この研削砥石を研削装置の回転軸に取り付け、円板部材を回転させながら、砥石部材の先端面を加工面に接触させることで、加工面を研削することができる。   As a grinding wheel, there is one in which an annular grinding stone member is projected from an outer peripheral edge portion of a side surface of a disk member. The processing surface can be ground by attaching the grinding wheel to the rotating shaft of the grinding apparatus and bringing the tip surface of the grinding wheel member into contact with the processing surface while rotating the disk member.

従来の研削砥石では、円板部材の中心を円中心とする円周上に、複数の取付穴が等間隔に配置されており、各取付穴に挿通したボルトを回転軸のねじ穴に螺合させることで、研削砥石が回転軸に取り付けられている（例えば、特許文献１参照）。   In conventional grinding wheels, a plurality of mounting holes are arranged at equal intervals on the circumference centered on the center of the disk member, and the bolts inserted into the mounting holes are screwed into the screw holes of the rotary shaft. By doing so, the grinding wheel is attached to the rotating shaft (for example, refer to Patent Document 1).

特開２００３−０１９６７１号公報JP 2003-019671 A

前記したような研削砥石を回転軸に取り付けたときには、加工面に対して砥石部材の平面出しを行う必要がある。既に研削に用いた研削砥石を再び回転軸に取り付けたときに、円板部材の周方向の位相がずれて取り付けられた場合には、加工面に対する研削砥石の平面出しが煩雑になる。そのため、研削砥石を回転軸に取り付けるときには、円板部材の周方向の位相を常に所定の位相に合わせることが望ましい。   When the grinding wheel as described above is attached to the rotating shaft, it is necessary to flatten the grindstone member with respect to the processing surface. When the grinding wheel already used for grinding is attached to the rotary shaft again, if the circumferential direction of the disk member is shifted, the leveling of the grinding wheel with respect to the work surface becomes complicated. Therefore, when attaching the grinding wheel to the rotary shaft, it is desirable to always match the circumferential phase of the disk member to a predetermined phase.

そこで、従来の研削砥石では、円板部材の一部にマークを付けたり、切り欠き部を形成したりして、円板部材の周方向の位相を認識することができるように構成されている。
しかしながら、円板部材にマークを付けた構成では、研削時にマークが汚れて見えなくなるという問題がある。また、円板部材に切り欠き部を形成した構成では、円板部材の重量バランスが不均衡になるという問題がある。 Therefore, the conventional grinding wheel is configured to recognize a phase in the circumferential direction of the disk member by marking a part of the disk member or forming a notch. .
However, in the configuration in which the mark is attached to the disk member, there is a problem that the mark becomes dirty and cannot be seen during grinding. Moreover, in the structure which formed the notch part in the disc member, there exists a problem that the weight balance of a disc member becomes imbalance.

本発明は、前記した問題を解決し、研削砥石を回転軸に取り付けたときに、円板部材の周方向の位相が所定の位相に合うように構成された研削砥石および研削装置を提供することを課題とする。   The present invention solves the above-described problems and provides a grinding wheel and a grinding apparatus configured so that a circumferential phase of a disk member matches a predetermined phase when the grinding wheel is attached to a rotating shaft.

また、前記した研削砥石と、前記研削砥石が取り付けられる回転軸と、を有する研削装置であって、前記回転軸の先端面には、前記各第一取付穴および前記各第二取付穴にそれぞれ連通する複数の取付穴が設けられている。 In order to solve the above problems, the present invention provides a grinding wheel comprising a disk member and a grindstone member protruding from a side surface of the disk member, wherein the disk member includes a plurality of first One mounting hole and a second mounting hole are provided, and the odd number of the first mounting holes are arranged at equal intervals on a circumference centered on the center of the disk member, and the first An even number of the second mounting holes excluding a number that is an even multiple of the number of mounting holes are arranged at equal intervals on a circumference centered on the center of the disk member.
Moreover, it is a grinding apparatus having the above-described grinding wheel and a rotating shaft to which the grinding wheel is attached, and each of the first mounting hole and each second mounting hole is provided at the tip surface of the rotating shaft.

また、第一取付穴および第二取付穴は、円板部材の中心を円中心とする円周上に配置されているため、円板部材の重量バランスを均等にすることができる。 In the present invention, the disc member of the grinding wheel has an odd number of first mounting holes arranged at equal intervals on the circumference, and an even number excluding a number that is an even multiple of the number of the first mounting holes. The second mounting holes are arranged at equal intervals on the circumference, and the first mounting of the disk member is formed on the rotating shaft of the grinding device by forming mounting holes communicating with the first mounting hole and the second mounting hole. The combination form of the hole and the second mounting hole and the mounting hole of the rotating shaft is limited to one. Therefore, when the grinding wheel is attached to the rotating shaft, the circumferential phase of the disk member can always be adjusted to a predetermined phase.

次に、研削装置２の回転軸５５に研削砥石１を取り付ける手順について説明する。
まず、図３（ｂ）に示すように、回転軸５５の先端面５５ａに、円板部材１０の他方の側面１０ｂを重ねて配置し、回転軸５５の取付穴５７ａ，５７ｂと第一取付穴１１および第二取付穴１２とを連通させる。
そして、一方の側面１０ａ側から第一取付穴１１および第二取付穴１２に挿通させたボルトＢの先端部を、回転軸５５の取付穴５７ａ，５７ｂに螺合させることで、回転軸５５の先端面５５ａに研削砥石１を取り付けることができる。 Next, a procedure for attaching the grinding wheel 1 to the rotating shaft 55 of the grinding apparatus 2 will be described.
First, as shown in FIG. 3 (b), the other side surface 10b of the disc member 10 is placed on the tip end surface 55a of the rotating shaft 55, and the mounting holes 57a, 57b and the first mounting holes of the rotating shaft 55 are arranged. 11 and the second mounting hole 12 are communicated with each other.
And the front-end | tip part of the volt | bolt B inserted in the 1st attachment hole 11 and the 2nd attachment hole 12 from the one side surface 10a side is screwed in the attachment holes 57a and 57b of the rotating shaft 55, The rotation shaft 55 The grinding wheel 1 can be attached to the front end surface 55a.

By doing so, the combination form of the 1st attachment hole 11 and the 2nd attachment hole 12 of the disc member 10, and the attachment holes 57a and 57b of the rotating shaft 55 is limited to one.
Therefore, when the grinding wheel 1 is attached to the rotary shaft 55, the circumferential phase of the disk member 10 can always be set to a predetermined phase (phase in FIG. 1A), so that a flat surface with respect to the processed surface can be obtained. Can be done easily.

また、第一取付穴１１および第二取付穴１２は、円板部材１０の中心Ｐを円中心とする円周上に配置されているため、円板部材１０の重量バランスが均等になっている。したがって、円板部材１０を回転させたときの振動を抑えることができ、加工面の研削を安定して行うことができる。   Moreover, since the 1st attachment hole 11 and the 2nd attachment hole 12 are arrange | positioned on the periphery centering on the center P of the disc member 10, the weight balance of the disc member 10 is equal. . Therefore, vibration when the disk member 10 is rotated can be suppressed, and the processing surface can be stably ground.
