Wl=k · Q1 · (P0 + P1) 式中k是常數；（P0 + P1)是泵21的輸出壓力。 在實際的工具機例子中，上述Q1大致爲200L/miii左 右，上述（P0 + P1)大致爲0.3MPa左右，因此，上述泵的消 耗功率較大，超過1台工具機的全部消耗功率的2 5 %左右 的情況不少。 【發明內容】 本發明是考慮這種情況而提出的，其目的是要在保持因 機械加工而產生的切屑的沖掉能力和加工時對需要潤滑部 位的潤滑能力的同時，減少供給處理液（處理液或洗滌液） 所需要的功率。 爲了達到上述目的’利用本發明的處理液供給方法，按 照如下方式實施：在工具機上，當間歇地向工件固定台和 固定在其上的工件等必要的部位，提供處理液或洗滌液等 的處理液時’使設置在適當筒度上的副液箱內所蓄存的處 理液，依靠重力作用流下而提供給上述必要的地方；另一 方面，將這樣供給的處理液回收至主液箱內，再用栗將該 主液箱內的處理液輸送至副液箱中。 在本發明中，在副液箱中蓄存的處理液的量，與每一次 開始供給處理液時的一次供給量大致一致。從而，該蓄存 312/發明說明書(補件)/92-03/91137461 7 200410786 的處理液’在重力作用下，在確保與必要的輸出壓力相當 的全揚程（例如’約爲〇·5〜l〇m)的狀態下，且以大於必要 的瞬時最大流量的方式，維持流動的狀態，並供給至工件 固定台和固定在其上的工件等。這種供給對沖去附著在工 件固定台和工件上的切屑特別有效。 另外’即使在停止從副液箱向工件固定台和工件供給處 理液的狀態下，也可以用泵將處理液輸送至副液箱，因此， 即使泵的輸出流量較小，到必要時，也可將必要量的處理 液輸送至副液箱內。 ^ 因此，採用以上這樣結構的本發明，泵只有較小的輸出 流量’但是即使副液箱內的任意點的處理液的全揚程較 小，也可以與現有同樣可靠地沖掉切屑，並且可以和以前 同樣可靠地對需要用處理液潤滑的部位進行潤滑。這樣， 在保持現有處理液的作用的情況下，與現有相比，可以大 大減小泵的消耗功率。 這時’利用本發明，當在副液箱內蓄存了必要的處理液 時，可以使利用泵進行的處理液輸送停止。這樣，就不會 再有多餘的處理液被輸送至副液箱內的情況，可進一步減 少泵的消耗功率量。 上述的本發明的裝置的結構爲，具有：主液箱，作爲供 向工件固定台或固定在其上的工件的需要供給處理液的部 位的處理液或洗滌液等處理液流入的容器；副液箱，作爲 容器設置在僅比上述工件固定台高一特定距離的位置上， 且蓄存有的處理液量與向上述需要供給處理液的部位的一 8 312/發明說明書(補件)/92-03/91137461 200410786 次供給量大約一致；泵，用於將上 送至上述副液箱；和液體流通管路裝 的處理液，依靠重力作用，隨時流出 液的部位。 在本發明中，蓄存在副液箱內的 致的處理液量，經過液體流通管路裝 的全揚程的狀態下，並且在以大於必 流出的狀態下，供給至需要供給處理 這種供給對沖去附著在工件固定台和 效。 在副液箱內的一次供給量的處理液 暫時停止從副液箱內供給，但是利用 液的方法，泵可以連續或不連續地將 送至副液箱內。這時，由於利用泵向 使是在停止從副液箱供給處理液時’ 使泵的輸出能力較小，泵也可以在供 次供給量大的處理液輸送至副液箱中 因此，採用以上這樣結構的本發明 能力，但是即使副液箱內的處理液的 與以前一樣可靠地進行切屑的沖.洗 滑。因此，在保持現有的處理液的作 相比，可以大幅度地減小泵的消耗功 上述發明能夠具體化爲如下方式。 即：這個裝置的結構如下：若將向 312/發明說明書(補件)/92-03/91137461 :主液箱內的處理液輸 :置，用來使副液箱內 至上述需要供給處理 大致與一次供給量一 置，可以在具有較小 要的瞬時最大流量而 液的部位。如上所述， 工件上的切屑特別有 流出後，雖然處理液 這種間歇式供給處理 主液箱內的處理液輸 副液箱內的輸送，即 也可進行，因此，即 給開始之前，將比一 〇 ’栗只有較小的輸出 全揚程較小’也可以 或需要潤滑部位的潤 用的情況下，與現有 率。 需要供給處理液的部 9 200410786 位間歇地供給處理液時的處理液的一次供給量記爲Q 1，將 該一次供給量的處理液從副液箱流向工件所用的流出時間 記爲T 1，而將從上述一次供給量的處理液流出開始至下一 次的一次供給量的處理液流出之前的時間記爲T2，則泵的 輸出流量Q，是在由式Qmin = Ql XT1/T2所算出的値以上， 但又比上述一次供給量的處理液的最大流量小。 這樣，在一次供給量的處理液流出後，在下次供給開始 前，泵將主液箱內的處理液輸送至副液箱。這時，泵的輸 出流量Q比一次供給量的處理液的最大流量還小，可減少 泵的功率消耗的浪費。 另外，形成如下的結構，將副液箱設置成其底面比工件 固定台的上面高0.5m〜10m左右。這樣，泵將處理液從主 液箱輸送至副液箱時的輸出壓力，可減少至例如先前的 1 /1 0左右，即使在這種情況下，仍能毫無妨礙地將處理液 提供給需要供給處理液的部位。另外，這時，泵的輸出壓 力降低會有助於大幅度地減少泵的消耗功率。 【.實施方式】 爲了更詳細地說明本發明，參照所附圖式而加以說明。 圖1〜圖3顯示本發明的工具機處理液供給裝置，圖1是 將一部分省略後的前視圖，圖2是側視圖，圖3是顯示處 理液供給系統的圖。 在這些圖中，1是基座，2是固定在基座1上的工件固 定台，3是用於將工件w固定在工件固定台2上的夾具，4 是形成於基座1上的工件加工裝置。 10 312/發明說明書(補件)/92·03/91137461 200410786 上述工件固定台2的結構是：將支承工件w用的支承部 件5、5固定在工作台上面，從而依靠重力作用’將流落在 工件w和工作台2上面的處理液s收集起來，使其流至其 他地方。 夾具3的結構是這樣的：利用左右的直立部件6、ό和I 藉助於軸7及固定裝置8而架設在部件6、6的上端之間的 水平部件 9，從而形成一個門型的壓緊結構；同時’ & #

In an actual machine tool example, the Q1 is approximately 200 L / miii and the (P0 + P1) is approximately 0.3 MPa. Therefore, the power consumption of the pump is large, exceeding 2% of the total power consumption of a machine tool. There are many cases around 5%. [Summary of the Invention] The present invention was made in consideration of this situation, and its purpose is to reduce the supply of processing liquid (while maintaining the ability to remove chips generated by machining and the ability to lubricate the parts that need lubrication during processing) Treatment fluid or washing fluid) required power. In order to achieve the above-mentioned purpose, the method for supplying a processing liquid according to the present invention is implemented as follows: On a machine tool, a processing liquid or a washing liquid is intermittently provided to necessary parts such as a workpiece fixing table and a workpiece fixed thereon. When the processing liquid is used, the processing liquid stored in the sub-tank provided at an appropriate cylinder is allowed to flow down to the above-mentioned necessary places by gravity; on the other hand, the processing liquid thus supplied is recovered to the main liquid. Inside the tank, the processing liquid in the main tank is transported to the sub tank by using chestnuts. In the present invention, the amount of the processing liquid stored in the sub-tank is substantially the same as the one-time supply amount each time the supply of the processing liquid is started. Therefore, the storage liquid of 312 / Invention Specification (Supplement) / 92-03 / 91137461 7 200410786 'under the action of gravity ensures a full head equivalent to the necessary output pressure (for example,' approximately 0.5 ~ 5 ~ l0m), and maintain a flowing state in a manner greater than the necessary instantaneous maximum flow rate, and supply it to the workpiece fixing table and the workpiece fixed thereon. This kind of supply hedge is particularly effective for removing chips adhering to the workpiece holding table and the workpiece. In addition, even when the supply of the processing liquid from the auxiliary liquid tank to the workpiece fixing table and the workpiece is stopped, the processing liquid can be delivered to the auxiliary liquid tank by the pump. Therefore, even if the output flow rate of the pump is small, when necessary, The necessary amount of processing liquid can be transferred to the sub tank. ^ Therefore, with the present invention having the above structure, the pump has only a small output flow rate, but even if the total head of the treatment liquid at any point in the sub-tank is small, the chips can be washed away as reliably as before, and Lubricate the parts that need to be lubricated with the treatment liquid as reliably as before. In this way, the power consumption of the pump can be greatly reduced compared with the conventional technology while maintaining the effect of the existing treatment liquid. In this case, according to the present invention, when the necessary processing liquid is stored in the sub-tank, the processing liquid transportation by the pump can be stopped. This eliminates the need for excess process liquid to be delivered to the sub-tank, and further reduces the power consumption of the pump. The above-mentioned apparatus of the present invention has a structure including: a main liquid tank, which is a container into which a processing liquid such as a processing liquid or a washing liquid is supplied to a part on which a processing liquid is to be supplied to a workpiece fixing table or a workpiece fixed to the workpiece; The liquid tank is set as a container only at a certain distance higher than the above-mentioned workpiece fixing table, and the amount of the stored processing liquid and the above-mentioned place where the processing liquid is to be supplied are required. 8 312 / Invention Specification (Supplement) / 92-03 / 91137461 200410786 The supply amount is approximately the same; the pump is used to send the liquid to the above auxiliary tank; and the processing liquid in the liquid circulation pipeline depends on the gravity, and the liquid flows out at any time. In the present invention, the amount of the treatment liquid stored in the auxiliary liquid tank is supplied to the supply hedging process that requires supply processing in a state of full head installed in the liquid circulation pipeline, and in a state of greater than necessary flow. De-attach to the workpiece fixing table and effect. The supply amount of the processing liquid in the auxiliary liquid tank is temporarily stopped from the auxiliary liquid tank. However, with the liquid method, the pump can continuously or discontinuously send the liquid to the auxiliary liquid tank. At this time, because the pump is used to stop the supply of the processing liquid from the auxiliary tank, the output capacity of the pump is small, and the pump can also deliver the processing liquid with a large supply amount to the auxiliary tank. Therefore, the above is adopted. The structure of the present invention is capable, but even if the processing liquid in the sub-tank is as reliable as before, the chips are washed and slipped. Therefore, the power consumption of the pump can be greatly reduced compared with the operation of the conventional treatment liquid. The above invention can be embodied as follows. That is, the structure of this device is as follows: If the processing liquid in the main tank is transferred to 312 / Invention Manual (Supplements) / 92-03 / 91137461: it is used to make the supply from the auxiliary tank to the above-mentioned need for processing. It can be placed at the same position as the one-time supply, and it can be used at the part with the smaller instantaneous maximum flow rate. As mentioned above, after the chips on the workpiece have flowed out, although the process liquid is intermittently supplied to the main liquid tank, the process liquid can be transported to the sub liquid tank. Therefore, before the start, The output is lower than the 10 'chestnut with only a smaller total head and it can also be used in the case of lubrication of the lubricating parts, with the existing rate. The number of parts required to supply the processing liquid is 200410786. When the processing liquid is intermittently supplied, the primary supply amount of the processing liquid is recorded as Q1, and the outflow time for the processing liquid to flow from the auxiliary tank to the workpiece is recorded as T1. The time from the start of the supply of the process liquid to the time of the next supply of the process liquid is denoted as T2, and the output flow rate Q of the pump is calculated by the formula Qmin = Ql XT1 / T2値 above, but it is smaller than the maximum flow rate of the processing liquid in the above-mentioned one-time supply. In this way, after the first supply of the processing liquid flows out, before the next supply is started, the pump transfers the processing liquid in the main tank to the sub tank. At this time, the output flow rate Q of the pump is smaller than the maximum flow rate of the processing liquid supplied at one time, and waste of power consumption of the pump can be reduced. In addition, a sub-tank is formed so that its bottom surface is about 0.5 m to 10 m higher than the top surface of the work fixing table. In this way, the output pressure of the pump when the processing liquid is transferred from the main tank to the auxiliary tank can be reduced to, for example, about 1/10 of the previous one. Even in this case, the processing liquid can be supplied to the tank without any hindrance. The part where the processing liquid needs to be supplied. In addition, at this time, a decrease in the output pressure of the pump will help to greatly reduce the power consumption of the pump.

Element symbol 23 is a pipeline that connects the filter tank 18 with the main liquid tank 19, so that the processing liquid s in the filter tank 18 flows into the main liquid tank under the action of gravity! 9 within. In addition, 24 is a suction pipe of the pump 21, and 25 is a funnel port fixed to the lower end of the suction pipe 24. The output flow rate Q of the above pump 21 can be determined as follows: when the processing liquid is intermittently supplied to the portion where the processing liquid is to be supplied, if the primary supply amount of the processing liquid s is Q 1; the primary supply amount of the processing liquid The outflow time of s from the sub-tank 20 to the workpiece w is T1; the time from the outflow of the processing liquid s from the first supply amount to the time before the outflow of the processing liquid s of the next supply amount is T2; then Q should be It is larger than Qmin 値 calculated from the formula Qmin = Qlx T 1 / T2, but smaller than the supply flow rate of the processing liquid of the above-mentioned primary supply; it is preferably approximately the same as Qmin 値. The component symbol 26 is a pipeline from the pump 21 to the auxiliary tank 20. A float-type on-off valve 27 is installed at the end of the pipe 26. When the amount of the processing liquid s in the sub-tank 20 substantially reaches the above-mentioned primary supply amount, the float on-off valve 2 7 stops the flow of the processing liquid from the pump 21 into the sub-tank 20. 2 8 is a bypass for overflowing the excess processing liquid s to the liquid tank 19 when the auxiliary liquid 12 312 / invention specification (Supplement) / 92-03 / 91137461 200410786 tank 2 is supplied with excess processing liquid s Pipeline. As shown in the example (Fig. 1, Fig. 3), this bypass line is injected around the fixture on the workbench (perimeter of the workbench), and chips and other debris scattered around the workbench are flushed out and removed. The upper side of the auxiliary liquid tank 20 is open to the atmosphere, and at the same time, its bottom surface 20 a is installed at a position h approximately 0.5 m to 10 m higher than the upper surface of the work fixing table 2 by a pair of left and right stays 29 and 29. In fact, in order to reduce the power consumption of the pump 21, this distance h can be about 2.5 m to 3 m; the capacity of the auxiliary tank is about 10L to 100L. The liquid flow line device 22 has a liquid flow line opening / closing device 30 formed on the bottom surface 20a of the sub-tank 20, and a tube extending downward from an outflow hole a of the liquid flow line opening / closing device 30. A pair of branch pipes 3 2, 3 2 formed by dividing the pipe 31 into two branches; and a nozzle 3 3 formed at the end of each branch pipe 32. When 30 is in the open state, the primary supply of the processing liquid s in the sub-tank 20 flows into the pipeline 31 and the branch pipeline 3 2 5 3 2 under the action of gravity, and then from each nozzle 3 3 in It is ejected within tens of seconds. When the liquid circulation pipeline device 30 is closed, the processing liquid s in the sub-tank 20 is prevented from flowing into the pipeline 31. At this time, the 'liquid circulation line opening / closing device 30' has a valve body 34 for closing the outflow hole a formed in the bottom surface 20a of the sub-tank 20, a link 35 fixed to the valve body 34, and the link for driving the link up and down. 3 5 Using the cylinder device 3 6. The valve body 34 is moved and raised by the shortening operation of the cylinder device 36, and the outflow hole a is opened. In addition, the cylinder device 36 is extended 13 312 / Invention Manual (Supplement) / 92-03 / 91137 1 200410786 actuated, the valve body 34 was lowered, and the outflow hole a was closed. The above-mentioned cylinder device 36 supplies compressed air through an air supply reversing valve (not shown), and the control operation of the control device 37 installed at the rear end of the base 1 can switch the air supply reversing valve. And for telescopic movement. In addition, each of the nozzles 33 can be a circular nozzle having a circular nozzle having a diameter of 6 to 8 mm, or a flat nozzle having a rectangular nozzle having a length of 4 mm and a width of 80 mm. Next, a usage example of the apparatus of the present invention and its operation will be described. In this example, multiple workpieces w are processed in sequence. The work of each working part can be performed automatically or manually by using the control action of the control device 37. After the first work w is fixed on the work fixing table 2 by the jig 3, the work is started while the pump is kept rotating. In this way, each of the main shafts 14 is rotated, and the combined chuck 13 is moved to the left in FIG. 2. The tool 16 fixed on each of the main shafts 14 starts to cut the workpiece w. Before the tool 16 starts to cut the workpiece w, The liquid flow line opening / closing device 30 of the liquid flow line device 22 is operated. In this way, the processing liquid s stored in the auxiliary liquid tank 20 in advance flows out from the nozzles 33 through the outflow hole a, the pipe 31, and the branch pipes 3, 3 2 under the action of gravity, and is continuously provided to the workpiece for fixing. The place where the stage 2 or the workpiece w fixed on it needs to be supplied _ liquid. Here, the part that requires the supply of the treatment liquid means that the stomach has washed away the chips generated by cutting the workpiece W with the tool 16 and needs to be supplied 312 / Invention Manual (Supplement) / 92-03 / 91137461 14 200410786 Treatment liquid S And a part where the processing liquid S needs to be supplied in order to lubricate the friction part between the workpiece w and the tool i 6. The flow rate of the process liquid s during the supply process is approximately the same as the instantaneous maximum flow rate required when the process liquid S is supplied to the place where the process liquid is to be supplied. The supply of the process liquid S is performed by using the tool 16 on the workpiece W. Continuously during cutting. The supplied processing liquid s flushes the chips adhering to the work fixing table 2 or the work w fixed thereon into the filter box 18, and simultaneously lubricates the parts that must be lubricated as the friction parts of the work and the tool. The chips and the processing liquid s flowing into the filter tank i 8 are separated and removed there, and the processing liquid s after the chips are removed flows into the main liquid tank 19 and is then conveyed to the auxiliary liquid tank 20 by the pump 21. When the cutting of the workpiece w by the tool 16 is completed, the liquid flow path opening and closing device 30 is operated, and the supply of the processing liquid s in the sub-tank 20 is stopped. In this way, the process liquid s in the sub-tank 20 continuously flows from the opening operation of the front liquid circulation pipeline opening and closing device 30 to its closing operation, and the continuous outflow is the above-mentioned one-time supply. the amount. When the supply of the processing liquid s is stopped, the fixation of the workpiece w by the jig 3 is released, and the processed workpiece w is sent to the next stroke. Then, the next work piece w is sent to the work piece fixing table 2, and the work piece w is fixed by the fixture 3 in the same manner as the previous work piece w. After that, the same processing is repeated. In the above embodiment, the necessary instantaneous maximum flow rate Q1 of the processing liquid s flowing from the sub-tank 20 is 200 L / min, and the primary supply amount of the processing liquid s flowing from the sub-tank 20 flows from the sub-tank 20 The required time T 1 is 20 seconds, starting from the outflow of the processing liquid from the above-mentioned one-time supply to the next one

The output flow Q of the pump 2 1 and the Qmin 値 calculated by the formula Qmin = Ql χΤ1 / Τ2, ie 40 L / mi η, are the same, the output pressure of the pump 2 1 (including the resistance of the pipeline) is 0 · 0 6 Μ P a 〇 In the conventional processing liquid supply device shown in FIG. 4 corresponding to the above embodiment, the flow rate when the processing liquid s is supplied to the place where the processing liquid needs to be supplied is usually 200 L / min, which is the instantaneous maximum flow rate Q1. The output pressure of the pump 21 is approximately 0.3 MPa. Under this condition, comparing the power consumption of the pump 21 with the above embodiment and the existing situation, the following results can be obtained. When the output pressure of the pump 21 is Pt (MPa) and the flow rate is Qt (L / min), the power consumption W (kw) of the pump 21 can be displayed by the formula: W = k · Pt · Qt. Therefore, the ratio of the power consumption W1 of the existing pump to the power consumption W2 of the pump of the above embodiment is: W1: W2 = (kx0.3x200): (kx0.06x 40) = 60: 2.4 ° From this result, The pump power W2 in the above embodiment is only 4% of the current pump power W1. Next, a modification example of the implementation example of the present invention will be described. In the above-mentioned embodiment, although the processing liquid s from the auxiliary tank 20 is also provided to the friction portion of the workpiece w and the tool 16, the lubrication of the workpiece w and the tool friction portion 16 is made by using the main shaft 1 4 When the processing liquid is supplied from the inside, the processing liquid s flowing out of the sub-tank 20 is not supplied to the friction portion of the workpiece w and the tool 16 but is only used for chip washing. In addition, in the case where it is not necessary to perform lubricating dry cutting of the friction part 16 312 / Invention specification (Supplement) / 92-03 / 91137461 200410786 of the workpiece w and the tool 16, it is not necessary to use a lubricant The processing liquid S is used to wash away the chips. In this case, as the processing liquid, a well-known washing liquid that emphasizes detergency can be used. When the output flow rate of the pump 21 is larger than the above Q m i n, the 'pump 2 1 does not need to be rotated continuously during the use of the machine tool. In this case, when the processing liquid s stored in the sub-tank / 20 is more than the appropriate amount of the primary supply of the processing liquid supplied from the sub-tank 20 at one time, it can be automatically made The rotation of the pump is stopped; however, when the processing liquid s stored in the sub-tank 20 is smaller than the one-time supply amount, the pump can be automatically started to rotate. In this case, the float-type on-off valve 27 can be omitted. In addition, it may be implemented as follows. The pump with a small output flow rate is continuously operated. During the operation, a slightly larger amount of processing liquid than the primary supply required when the workpiece is operating is supplied to the auxiliary tank 20. A little more treatment liquid can also be returned to the main liquid tank through the bypass line, which are all within the scope of the present invention. (Industrially available) With the present invention having the above structure, the pump has only a small output flow rate, and even if the total head of the treatment liquid in the sub-tank at any point is small, the chips can be washed away reliably, and It can reliably lubricate the place that needs to be lubricated with the treatment liquid. Therefore, in the case where the flushing effect and the lubricating effect of the treatment liquid are kept the same, the rated output of the pump or its power consumption and power consumption can be greatly reduced compared with the existing devices.
