Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The coolant used in machine tools evaporates due to the processing heat during operation and is not chipped, and it adheres to the work and is reduced. This phenomenon is particularly noticeable in recent years due to improved workability, and the coolant must be replenished frequently. On the other hand, the water-soluble coolant automatic replenishing device of the present invention can supply the necessary coolant to multiple machine tools only by piping, so that machining problems due to the coolant can be prevented.

[0002]

[Prior art]

 In the past, as shown in Fig. 3, the coolant was replenished by mixing it in the main coolant diluting mix tank to form a diluting liquid, which was automatically replenished to each of the multiple machining mother machines via the control valve. Therefore, a level switch for detecting the liquid level insufficiency of the coolant tank of the processing mother machine to open and close the control valve, and the electrical wiring accompanying it are required.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional automatic replenishment is supplied to the coolant tanks of multiple machine tools, but a level switch for starting and stopping the pump of this device at the end of the pipe, and a plurality of its arrangement and wires are required. It is troublesome and expensive. This is solved and the level switch and its wiring are unnecessary.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and is a float type level device for quantitative detection in a tank device that automatically distributes and replenishes coolant to multiple machine tools that use water-soluble coolant. A switch is provided for each tank for diluting the coolant and for the undiluted solution of the coolant, and this tank is placed on the coolant diluting tank. In the automatic water replenishment device for water-soluble coolant that keeps the coolant concentration in the coolant diluting tank constant through a control valve, a coolant supply pump, pressure tank, and pressure switch are provided, and the machining mother machine coolant When the tank's manual or automatic valve is opened, the pressure switch operates and activates the coolant supply pump, It is a mechanism for supplying the door to more of the working mother machine coolant tank.

[0005]

[Work]

 The automatic replenisher for water-soluble coolant of the present invention is mainly composed of a coolant diluting tank, is equipped with an air pressure type coolant stock solution tank on the side of the tank, and is also equipped with a tank for the coolant stock solution on the tank. . An injection pipe via a control valve is installed in the upper mouth of each of these tanks, and this control valve is operated by a float type level switch provided in each tank. In the lower part, a pipe is connected to the coolant dilution tank via a control valve. In addition, a coolant supply pump that distributes the coolant to multiple mother machines, a pressure switch, and a pressure tank are mounted on the main coolant tank, and dedicated piping is prepared for each mother machine.

In the automatic replenishing device for the water-soluble coolant having such a structure, when a replenishment sign is issued from the float type level switch of the coolant diluting tank to the tank, both the water tank and the coolant stock solution tank are supplied. The control valves at the upper mouths of the tanks are opened, and injection into the respective tanks is started. The control valves at the upper mouths of the tanks are operated by the signs of the float type level switches to ensure the fixed amount of each tank. When the volume of both tanks reaches a fixed amount, the control valve under the stock solution tank opens and drops it into the coolant diluting tank to replenish it as a diluting solution with a certain concentration. When the liquid level in the coolant tank of the multi-processing mother machine is insufficient, the manual or automatic control valve is opened and liquid is supplied to the coolant tank. When the pressure drops below a certain level, the pressure switch operates and the coolant pump starts, and liquid is supplied to the coolant tank of the processing machine until the liquid level is sufficient.

【Example】

 An embodiment of an automatic replenisher for water-soluble coolant of the present invention will be described with reference to FIGS. 1 and 2. A float type level switch 2 is installed on the coolant dilution tank 1, a stirrer 3 is installed, a coolant stock solution tank 4 is installed, a float level switch 5 is installed, and the top of the tank is opened. A pipe 8 via a control valve 6 is connected to the. Others On the side surface of the coolant dilution tank 1, a coolant stock solution tank 12 into which a pressure air pipe 11 is inserted is housed in a reinforcing frame 13, and a coolant stock solution discharge pipe 14 is connected to an upper opening control valve 6 of the stock solution tank 4 described above. Has been done. On the other hand, the coolant pump 16 on the coolant diluting tank 1 is a pump that pumps the coolant to each processing mother machine through a plurality of control valve groups 17, and between the coolant pump 16 and the control valve group 17 is in front of the valve group. Distribution pipes are provided, and each valve of the control valve group 17 is provided with a dedicated pipe for each processing mother machine. The stirrer 3 is constantly operated so that the dilution concentration of the coolant in the coolant dilution tank 1 is always kept uniform. When the control valve 17 is opened automatically or manually, the pressure switch 19 outputs a signal of pressure drop, starts the pump and supplies the coolant to the machining mother machine coolant tank. The pressure tank 20 is used to pump the supply liquid without pulsation.

In the automatic water-soluble coolant replenishing device having the above-described structure, when the coolant diluting work start sign is first issued to the coolant diluting tank 1, the coolant diluting tank 1 and the coolant stock solution tank 4 are The upper mouth control valve 67 of both tanks is opened, and the water and the coolant stock solution are injected into the both tanks 1 and 4. Then, each float type level switch 2 and 5 catches the fixed amount of each tank 1 and 4, and a sign is given to each upper mouth control valve 6 and 7 to stop the injection as appropriate, and both tanks 1 and 4 are fixed. At this point, the control valve 9 at the bottom of the stock solution tank is opened, and the stock solution is dropped into the coolant dilution tank 1 through the pipe 10 and is stirred by the stirrer 3 to dilute the coolant to a certain concentration. To create. Further, the stock solution in the stock solution tank 12 contained in the reinforcing frame 13 is constantly applied with the air pressure from the pressure air pipe 11 to the surface 15 of the stock solution, and the stock solution is discharged to the control valve 6 by the pipe 14. The pressure is fed, and the injection amount into the coolant liquid tank 4 is controlled by the control valve 6 by the catch of the float type level switch 5. This may be sucked by a pump instead of air pressure. In addition, the coolant is automatically replenished to each machining mother machine by operating the corresponding valve of the control valve group 17 by the replenishment sign from the machining mother machine and replenishing the machining mother machine with a dedicated pipe. Note that these automatic operations are performed by the electric control device mounted on the coolant dilution tank 1 and the operation panel thereof.
