중앙집중식 절삭유 자동보충시스템{centralized cutting fluid auto supplement system}Centralized cutting fluid auto supplement system

본 발명은 공작기계용 절삭유(Coolant)공급장치에 관한 것으로, 보다 상세하게는 공작기계별로 구비된 절삭유공급장치에서 절삭유가 부족해지면 저장탱크에 절삭유를 자동으로 보충하는 중앙집중식 절삭유 자동보충시스템에 관한 것이다.The present invention relates to a coolant supply device for a machine tool, and more particularly, to a centralized coolant automatic replenishment system for automatically replenishing cutting oil to a storage tank when the coolant is insufficient in a coolant supply device provided for each machine tool. will be.

공작기계에서는 가공속도를 높이기 위하여 가공물과 공구의 접촉에 따른 발열로 공구가 소손되는 것을 방지하고 가공물의 가공면을 보호하기 위하여 가공부위의 온도를 낮출 수 있도록 공구와 가공물의 접촉되는 부위에 절삭유가 자동으로 공급되게 하는 장치를 구비하고 있다.In the machine tool, cutting oil is applied to the contact area between the tool and the workpiece to prevent the tool from being burned due to heat generated by the contact between the workpiece and the tool, and to lower the temperature of the workpiece to protect the machining surface of the workpiece. It is provided with a device for automatically supplying.

절삭유는 방청제, 계면활성제 등을 물로 일정비율 희석한 것으로 사용한 절삭유는 회수하여 여과장치를 거쳐 재사용하나 가공작업 중의 발열로 인한 증발이나 비산 및 절삭칩 등에 의하여 손실이 발생한다.Cutting oil is obtained by diluting a certain ratio of rust inhibitor, surfactant, etc. with water. The cutting oil is recovered and reused through a filtration device, but loss occurs due to evaporation, scattering, and cutting chips due to heat generated during processing.

가공작업 중에 절삭유공급이 중단되면 공구의 소손이나 가공면에 훼손이 발생할 수 있으므로 공작기계의 가동을 즉시 중단하고 절삭유를 보충한 후 가공을 재개하면 가공정지 전·후의 가공면에 미세한 가공 정도의 차이가 발생하므로 공작기 계에서는 절삭유가 중단없이 공급되는 것이 필요하다.If the coolant supply is interrupted during machining, damage to the tool or damage may occur.If the machine tool is stopped immediately and the coolant is replenished, the machine can be restarted after resuming the machining. In the machine tool system, it is necessary that the coolant is supplied without interruption.

근래 공작기계에서의 무인화, 자동화가 진행됨에 따라 한 사람이 여러 대의 공작기계를 담당하거나 작업자가 고정배치되지 않는 경우가 있으므로 공작기계별로 구비된 절삭유공급장치에서 절삭유가 정상적으로 공급되는지의 여부를 확인하기 어려웠다.In recent years, as unmanned and automated machine tools are in progress, a person may be in charge of several machine tools or operators may not be fixedly arranged. Therefore, check whether the coolant is normally supplied from the coolant supply device provided for each machine tool. It was difficult.

종래 공작기계의 절삭유를 자동으로 보충할 수 있는 시스템으로는 알려진 것이 없었으므로 공작기계에 대한 절삭유의 보충은 작업자가 공작기계별로 절삭유저장탱크를 수시로 확인하고 부족분을 보충하고 있었다.Since there is no known system that can automatically replenish the cutting oil of the conventional machine tool, the replenishment of the cutting oil for the machine tool has been made by the operator from time to time to check the cutting oil storage tank for each machine tool and make up for the shortage.

본 발명은 공작기계별로 구비된 절삭유저장탱크에 부족한 절삭유를 자동으로 보충할 수 있게 하는 시스템을 구비하여 절삭유의 공급부족으로 공작기계의 가동중지나 공구 또는 가공물이 훼손되는 것을 방지하는 것이다.The present invention is provided with a system for automatically replenishing the cutting oil lacking in the cutting oil storage tank provided for each machine tool to prevent the operation of the machine tool or damage to the tool or workpiece due to the lack of cutting oil supply.

본 발명은 절삭유의 보충작업을 무인·자동화할 수 있도록 방청제, 계면활성제와 물을 혼합·희석하여 절삭유를 생산하는 장치를 중앙집중식으로 설치하고 절삭유생산장치에서 생산된 절삭유는 배관을 통하여 개별공작기계에 구비된 절삭유 저장탱크로 공급될 수 있게 구성하고 절삭유저장탱크에는 수위에 따라 밸브가 개폐되는 볼탑장치를 구비하여 절삭유저장탱크에 일정한 수위의 절삭유가 저장될 수 있게 구성한다.The present invention centrally installs a device for producing cutting oil by mixing and diluting rust inhibitor, surfactant and water so that cutting oil can be unattended and automated, and the cutting oil produced in the cutting oil production device is machined through a pipe. It is configured to be supplied to the cutting oil storage tank provided in the cutting oil storage tank is provided with a ball top device to open and close the valve in accordance with the water level is configured to be stored in the cutting oil storage tank to a certain level of cutting oil.

본 발명은 공작기계에서 절삭유의 공급중단으로 가동을 중지하거나 공구가 소손되는 것을 방지할 수 있을 뿐 아니라 공작기계별로 절삭유의 잔량확인이나 보충하는 작업을 생략하게 할 수 있어 작업자의 부주의나 태만 등에 의한 작업불량을 방지할 수 있고 인력을 절감하게 할 수 있게 하는 효과가 있다.The present invention can not only stop the operation due to the supply of cutting oil in the machine tool or prevent damage to the tool, but also can omit the remaining amount of cutting oil or replenishing the cutting oil for each machine tool. There is an effect that can prevent bad work and save manpower.

절삭유생산장치(1)에서 생산되는 절삭유는 절삭유저장탱크(6)로 이송되어 일정한 량이 저장되게 하고, 저장된 절삭유는 절삭유공급배관(7)을 통하여 배출된다.The cutting oil produced in the cutting oil production apparatus 1 is transferred to the cutting oil storage tank 6 to store a predetermined amount, and the stored cutting oil is discharged through the cutting oil supply pipe 7.

절삭유저장탱크(6)에는 절삭유의 수위를 감지하는 수위센서(8)가 구비되며 수위센서(8)의 신호에 의하여 절삭유생산장치(1)의 전원은 온·오프되게 하여 상시 자동으로 일정량의 절삭유가 저장되게 구성한다.The cutting oil storage tank 6 is provided with a level sensor 8 for detecting the level of cutting oil, and the power of the cutting oil production device 1 is turned on / off by a signal of the level sensor 8 so that a certain amount of cutting oil is always automatically. Configure to save.

절삭유저장탱크(6)에 저장된 절삭유는 절삭유공급배관(7)으로 배출되며 절삭 유공급배관(7)은 항상 일정한 압력을 유지하게 하는 가압펌프(9)로 압력을 가하거나 절삭유저장탱크(6)의 설치위치를 높게 하여 중력에 의하여 가압되게 하면 가압펌프(9)는 생략할 수도 있다.The cutting oil stored in the cutting oil storage tank 6 is discharged to the cutting oil supply pipe 7 and the cutting oil supply pipe 7 is pressurized by a pressurized pump 9 which maintains a constant pressure at all times, or the cutting oil storage tank 6. The pressurized pump 9 may be omitted if the installation position of the pressurizer is increased by gravity.

절삭유저장탱크(6)에서 절삭유공급배관(7)을 따라 배출되는 절삭유는 각각의 공작기계에 구비된 절삭유공급장치(도면미도시)의 저장탱크(10)로 공급된다.The cutting oil discharged along the cutting oil supply pipe 7 from the cutting oil storage tank 6 is supplied to the storage tank 10 of the cutting oil supply device (not shown) provided in each machine tool.

공작기계에 설치되는 절삭유공급장치는 통상 저장탱크와 사용한 절삭유를 회수하는 장치 및 회수된 절삭유를 여과하는 필터를 구비하고 절삭유를 가공부위에 토출하는 토출부로 구성되어 있다.A cutting oil supply device installed in a machine tool is usually composed of a storage tank, an apparatus for recovering used cutting oil, and a discharge part including a filter for filtering the recovered cutting oil and discharging the cutting oil to a machining portion.

절삭유공급장치의 저장탱크(10)에는 절삭유의 수위에 따라 절삭유공급배관(7)에서 공급되는 절삭유의 공급을 차단할 수 있게 하고 적정수위를 유지할 수 있게 하는 볼탑밸브(11)가 구비되어 저장탱크(10)의 수위를 항상 일정하게 유지할 수 있게 구성한다.The storage tank 10 of the cutting oil supply device is provided with a ball top valve 11 for cutting off the supply of cutting oil supplied from the cutting oil supply pipe 7 according to the cutting oil level and maintaining an appropriate level. It is configured to keep the water level in 10 always constant.

절삭유생산장치(1)의 절삭유저장탱크(6)에서 각각의 공작기계의 저장탱크(10)로 공급되는 절삭유공급배관(7)은 공급되는 절삭유에 가해지는 압력이 높지 않고 개별공작기계에서 소모되는 절삭유의 양이 많지 않으므로 대략 6mm정도의 내경을 갖는 호스 또는 파이프로 배관하는 것이 바람직하며, 절삭유공급배관(7)은 공작기계에 동력을 공급하는 전원선과 함께 배관하는 것이 설치 및 관리상 편리하다.The cutting oil supply pipe (7) supplied from the cutting oil storage tank (6) of the cutting oil production device (1) to the storage tank (10) of each machine tool does not have high pressure applied to the supplied cutting oil and is consumed by the individual machine tool. Since the amount of cutting oil is not large, it is preferable to pipe with a hose or a pipe having an inner diameter of about 6 mm, and the cutting oil supply pipe 7 may be conveniently connected with a power line for supplying power to the machine tool.

아울러 절삭유공급배관(7)은 경질의 재료인 금속 또는 합성수지재의 파이프를 사용할 수 있으나 설치의 편의를 위하여 유연한 합성수지재의 호스를 사용하여도 무방하다.In addition, the cutting oil supply pipe 7 may use a pipe of metal or synthetic resin, which is a hard material, but may be a flexible synthetic resin hose for convenience of installation.
