(57) [Summary] [Purpose] To improve the durability and reduce operating costs of a device that supplies high-pressure cutting oil to a machine tool (carbide spiral oil hole drill). [Structure] Cutting oil D in an oil tank 1 is supplied to the lower part of a cylinder 2 by a pump P via a check valve 4 to fill the inside of the cylinder 2. This allows the cylinder 2 to be overlaid from the top.
The flowing cutting oil D' is circulated to the oil tank 1 via the normally open valve 6. When operating the machine tool (carbide spiral drill with oil hole) 10, the air compressor 7 is operated to supply air to the upper part of the cylinder 2 through the normally closed valve 9, thereby cutting the inside of the cylinder 2. Oil D' is pressed down and pressurized. As a result, the cutting oil D' in the cylinder 2 is pumped through the flexible hose 11 to the machine tool (carbide spiral drill with oil hole) 10. [Effect] Since the pump P is activated when necessary and circulates the cutting oil D, a low-pressure pump can be used. As a result, the problems of devices that pump cutting oil directly using a high-pressure pump are solved, and costs are also reduced. This reduces the production cost of the workpiece.

ポンプを始動すると、油槽内の切削油は送油管、逆止弁を通してシリンダ内下 部に送油される。 シリンダ内部が切削油で満たされると、シリンダ上部に配管した送油管にオ− バ−フロ−し、この時ノ−マルオ−プンバルブは開状態にあるので、余った切削 油は送油管、ノ−マルオ−プンバルブを通り油槽内へ還元される。 ポンプを停止すると、シリンダへの切削油供給が止まり、当該シリンダ内には 一定量の切削油が貯留される。 When the pump is started, the cutting oil in the oil tank flows down into the cylinder through the oil pipe and check valve. Oil is sent to the area. When the inside of the cylinder is filled with cutting oil, an oil pipe connected to the top of the cylinder is filled with oil. The bar flows, and at this time the normally open valve is in the open state, so the excess cutting The oil passes through the oil pipe and the normally open valve and is returned to the oil tank. When the pump is stopped, the supply of cutting oil to the cylinder is stopped, and the inside of the cylinder is A certain amount of cutting oil is stored.
【０００７】 工作機械を作動させる時は、エアコンプレッサ−を始動する。これによって送 気管に供給されるエアは、ノ−マルクロ−ズバルブが開状態にあるのでシリンダ の上部へ供給され、当該シリンダの上部空間部が加圧され、シリンダ内の切削油 を下方に加圧する。これによって切削油は可撓性ホ−スを通り工作機械（超硬ス パイラル油穴付ドリル）へ圧送される。 エアコンプレッサ−作動中は、ノ−マルオ−プンバルブは閉状態にあることで 、エアが油槽内へ漏れることはない。 また、ポンプとシリンダ間には逆止弁を配設してあるので、エアコンプレッサ −作動中にシリンダ内の切削油がポンプ側へ逆流することはない。[0007] When operating the machine tool, start the air compressor. This will send The air supplied to the trachea is supplied to the cylinder because the normally closed valve is open. The cutting oil in the cylinder is supplied to the upper part of the cylinder, and the upper space of the cylinder is pressurized. Pressurize downward. This allows the cutting oil to pass through the flexible hose to the machine tool (carbide hose). The oil is fed under pressure to a drill with a spiral oil hole. While the air compressor is operating, the normally open valve is closed. , air will not leak into the oil tank. In addition, a check valve is installed between the pump and cylinder, so the air compressor - Cutting oil in the cylinder will not flow back to the pump side during operation.

Oil is sent to the lower part of the oil tank 1 and cylinder 2 installed inside the machine tool body (not shown). A pipe 3 is installed to supply the cutting oil D inside the oil tank 1 to the lower part of the cylinder 2. In order to make it possible, a pump P and a check valve 4 are installed in the middle of the oil pipe 3. As a result, cutting oil D' is supplied into the cylinder 2. Then, the inside of cylinder 2 is set in advance. The cutting oil is filled by a set amount of oil, and then the amount of cutting oil is increased by supplying more than this set amount of oil. D' overflows, but with this overflow of cutting oil D', the above oil An oil pipe 5 is installed between the upper part of the cylinder 2 and the oil tank 1 so that the oil can be returned to the tank 1. It is shown.
【００１０】 上記切削油加圧手段Ｂは次のように構成されている。 エアコンプレッサ−７とシリンダ２の上部に送気管８が配設され、該送気管８ の途中には２ポ−ト２位置切換弁としてのノ−マルクロ−ズバルブ９が配設させ てあり、これによってエアをエアコンプレッサ−７によってシリンダ２の上部に 供給し、シリンダ２内の切削油Ｄ′を押し下げ加圧するよう構成されている。0010 The cutting oil pressurizing means B is constructed as follows. An air pipe 8 is disposed above the air compressor 7 and the cylinder 2. A normally closed valve 9 as a 2-port 2-position switching valve is installed in the middle of the valve. This allows air to be pumped into the upper part of cylinder 2 by air compressor 7. The cutting oil D' in the cylinder 2 is pressed down and pressurized.
【００１１】 さらに、上記切削油圧送手段Ｃは次のように構成されている。 上記シリンダ２の底部と工作機械、即ち超硬スパイラル油穴付ドリル１０を可 撓性ホ−ス１１で接続して構成されており、前記した切削油加圧手段Ｂによって 加圧されたシリンダ２内の高圧切削油Ｄ′は上記可撓性ホ−ス１１を通して超硬 スパイラル油穴付ドリル１０に圧送される。[0011] Furthermore, the cutting hydraulic pressure sending means C is constructed as follows. The bottom of the cylinder 2 and the machine tool, that is, the carbide spiral drill with oil hole 10 can be connected. It is connected by a flexible hose 11, and is operated by the cutting oil pressurizing means B mentioned above. The high-pressure cutting oil D' in the pressurized cylinder 2 passes through the flexible hose 11 to the carbide The oil is fed under pressure to the drill 10 with a spiral oil hole.
【００１２】 こゝで、前記したノ−マルオ−プンバルブ６は、通常は開状態にあるのに対し て前記したノ−マルクロ−ズバルブ９は閉状態に保持されており、エアコンプレ ッサ−７の始動にノ−マルクロ−ズバルブ９は連動して開き動作し、この時、ノ −マルオ−プンバルブ６が閉じ動作され、また、エアコンプレッサ−７を停止す るとノ−マルクロ−ズバルブ９が閉じ動作し、これによりノ−マルオ−プンバル ブ６は開状態に復帰するよう、上記ノ−マルオ−プン及びクロ−ズ両バルブ６、 ９は連動連結されている。0012 Here, while the normal open valve 6 mentioned above is normally in an open state, The normally closed valve 9 mentioned above is kept closed, and the air compressor is turned off. The normally closed valve 9 opens in conjunction with the start of the sensor 7, and at this time, the - The open valve 6 is closed and the air compressor 7 is stopped. Then, the normally closed valve 9 closes, which causes the normally open valve to close. Both the normally open and closed valves 6, 9 are interlocked and connected.
【００１３】 而して、エアコンプレッサ−７を停止している時はノ−マルクロ−ズバルブ９ は閉状態にあるので、シリンダ２への給油時、該シリンダ２内の切削油Ｄ′がエ アコンプレッサ−７側へ流されることはない。また、エアコンプレッサ−７作動 時は、ノ−マルオ−プンバルブ６は閉状態にあることで、エアが送油管５、油槽 １へ漏れることはない。 さらに、ポンプＰとシリンダ２間には逆止弁４が配設されているため、エアコ ンプレッサ−７によりシリンダ２内が加圧されても切削油Ｄ′がポンプＰ側へ逆 流することはない。 因に、工作機械として図示例の超硬スパイラル油穴付ドリル１０を使用する時 の切削油には、ＪＩＳＷ１種２号（エマルジョン）を５倍程度に希釈して使用さ れる。[0013] Therefore, when the air compressor 7 is stopped, the normally closed valve 9 is in the closed state, so when cylinder 2 is refueled, the cutting oil D' in cylinder 2 is It will not flow to the acompressor 7 side. In addition, air compressor 7 is activated. At this time, the normally open valve 6 is in the closed state, and air is supplied to the oil pipe 5 and the oil tank. It will not leak to 1. Furthermore, since a check valve 4 is provided between the pump P and the cylinder 2, the air Even if the inside of the cylinder 2 is pressurized by the compressor 7, the cutting oil D' will not flow back to the pump P side. It won't flow. Incidentally, when using the illustrated carbide spiral drill with oil hole 10 as a machine tool, JISW Class 1 No. 2 (emulsion) diluted approximately 5 times is used as the cutting oil. It will be done.

本考案は、以上説明したように構成されているので、ポンプＰを必要な時（シ リンダ内の切削油量が少なくなった時）に作動させ、切削油を循環させるので、 当該ポンプＰには低圧ポンプを使用でき、その結果、従来例の高圧ポンプで切削 油を工作機械に圧送することによる問題点が解消され、経費も節減されることで 、被工作物の生産コストを低減できる等の効果がある。 Since the present invention is configured as explained above, the pump P is activated when necessary (in the system). It operates when the amount of cutting oil in the cylinder is low) and circulates the cutting oil. A low-pressure pump can be used for the pump P, and as a result, cutting can be performed using a conventional high-pressure pump. Problems caused by pumping oil to machine tools are eliminated and costs are saved. This has the effect of reducing the production cost of the workpiece.
