【考案の詳細な説明】
（産業上の利用分野）
この考案は、マシニングセンターの砥石カバー
に関するものである。[Detailed description of the invention] (Field of industrial application) This invention relates to a grindstone cover for a machining center.
（従来の技術）
マシニングセンターの主軸に砥石を挿着して研
削作業等を行なうことがあるが、この作業中に砥
石が折損して欠片が飛散すると危険である。(Prior Art) A grinding wheel is sometimes inserted into the main shaft of a machining center to perform grinding work, but it is dangerous if the grinding wheel breaks during this work and fragments fly off.
ところが、従来は砥石カバーが設けられておら
ず、これは砥石のカバーを取付けると砥石の着脱
時および砥石以外の工具に交換する時に邪魔にな
るからである。 However, conventionally, a grindstone cover has not been provided, because if a grindstone cover is attached, it will get in the way when the grindstone is attached/detached or replaced with a tool other than the grindstone.

ある。(Problem that the invention aims to solve) This invention protects the grindstone safely during operations such as grinding in a machining center, and prevents it from getting in the way when attaching or removing the grindstone or replacing it with a tool other than the grindstone. The present invention aims to solve the above-mentioned conventional problems by providing a grindstone cover with a new structure.

とを要旨とするものである。(Means for Solving the Problems) In order to solve these problems, this invention proposes a method in which the cover body is rotatably attached to the spindle head to protect the grindstone that is attached to and removed from the main spindle of the machining center. The gist is that an opening/closing drive mechanism is provided which opens the cover main body to a position to avoid interference with the grindstone when the grindstone is attached or removed, and closes it when it is inserted into the main shaft.
（実施例）
以下、図示の実施例によりこの考案を具体的に

よび動作時に同期して作動し、前記カバー本体１
を開閉できるようにしてある。 In the figure, reference numeral 1 denotes a cover body, which is rotatably attached to a spindle head 2 of a machining center via a support member 3 and a shaft rod 4. This cover main body 1 has a cover portion 1a at the tip, and the main shaft head 2
The grinding wheel 5 inserted into the main shaft 2a of the grinding wheel 5 is covered from above so that it can be protected. Reference numeral 6 denotes a swing arm, one end of which is fixed to the end of the shaft rod 4, and the other end of which is provided with a long hole 6a. Reference numeral 7 denotes a drive device fixed to the spindle head 2, which in the illustrated example consists of an air cylinder.The tip of the plunger 7a engages with the long hole 6a of the swing arm 6, and the movement of the plunger causes the drive device to move. The swing arm 6 can be rotated. This drive device 7 operates in synchronization with the attachment/detachment and operation of the grindstone 5, and
It is designed so that it can be opened and closed.
即ち、砥石５の着脱時には、前記プランジヤー
７ａが伸び出て前記スイングアーム６を回動さ
せ、この回動に伴なつて前記軸棒４が回転するこ
とにより前記カバー本体１を回動させ、第３図に
示すようにカバー本体１を開いた状態に保持する
ことができる。 That is, when attaching or detaching the grindstone 5, the plunger 7a extends and rotates the swing arm 6, and in conjunction with this rotation, the shaft rod 4 rotates, thereby rotating the cover body 1. As shown in FIG. 3, the cover body 1 can be held in an open state.
一方、砥石５の動作時には、前記プランジヤー
７ａが徐々に引つ込んでスイングアーム６を前記

り、砥石の欠片等の飛散を未然に防止して作業の
安全を確保することができる。 On the other hand, when the grinding wheel 5 is in operation, the plunger 7a gradually retracts and rotates the swing arm 6 in the opposite direction to the above, and as shown in FIGS. The cover main body 1 can be held in a closed state. When the cover body 1 is closed, the grinding wheel 5 is sufficiently covered to the extent that it does not interfere with work such as grinding, and this prevents fragments of the grinding wheel from scattering, ensuring work safety. can do.
