머시닝 센터의 절삭유 필터링장치Coolant filtering device of machining center

본 발명은 머시닝 센터의 절삭유 필터링장치에 관한 것으로서, 더욱 상세하게는 공작물의 가공을 위한 잘삭유가 칩(chip)을 함유한 상태로 회유되면서 걸르는 필터를 다양하게 적용시키도록 하고, 필터링을 위한 구조를 보다 간단하게 구성하도록 하는 머시닝 센터의 절삭유 필터링장치에 관한 것이다.The present invention relates to a coolant filtering device of a machining center, and more particularly, to allow various applications of a filter to be filtered while lubricating oil for machining a workpiece containing chips. It relates to a coolant filtering device of a machining center to make a simpler.

일반적으로 공작물의 3차원 가공을 위한 머시닝 센터는 절삭공구의 발달과 공구의 보호, 가공성 향상 및 표면조도 개선 등을 목적으로 고압(30bar)의 절삭유를 사용하고 있다.In general, the machining center for the three-dimensional machining of the workpiece uses a high pressure (30bar) of cutting oil for the purpose of development of cutting tools, protection of the tool, improving workability and surface finish.

고압용 절삭유를 사용하기 위해서는 고압을 발생시키도록 하는 펌프와 가공중에 사용된 절삭유를 여과하는 필터링장치가 필수적으로 구비된다.In order to use high pressure coolant, a pump for generating high pressure and a filtering device for filtering the coolant used during processing are essentially provided.

필터링장치의 구비목적은 공작물의 절삭가공 중에 발생되는 칩(chip)이 절삭유에 함유되는데 절삭유는 재사용을 목적으로 순환시키게 구성되어 있기 때문에 순수한 절삭유만을 채집하여 재순환하도록 하기 위함이다.The purpose of the filtering device is to collect chips that are generated during cutting of the workpiece in the cutting oil. The cutting oil is configured to circulate for the purpose of reuse, so that only pure cutting oil is collected and recycled.

한편, 종래 머시닝 센터의 절삭유 필터링장치는 도 1A 에서와 같이 메인탱크(10)로부터 펌핑된 절삭유가 머시닝 센터(12)의 공작물 절삭부분으로 유입되면서 냉각 또는 윤활시키고, 칩이 함유된 절삭유는 보조탱크(14)로 모인다.Meanwhile, the coolant filtering apparatus of the conventional machining center cools or lubricates the coolant pumped from the main tank 10 as it flows into the workpiece cutting part of the machining center 12 as shown in FIG. 1A, and the coolant containing the chip is stored in the auxiliary tank. Gather with (14).

상기 보조탱크(14)에는 유입된 절삭유의 수위를 감지하는 수위감지센서(16)가 설치되어 있고, 이 센서(16)가 상한수위를 감지하게 될 때 회수용 펌프(18)를 작동시킨다. 상기 보조탱크(14)의 절삭유는 회수용 펌프(18)에 의해 다시 메인탱크(10)로 보내지게 되는 한편, 상기 회수용 펌프(18)와 메인탱크(10) 사이의 유로에는 상기 보조탱크(14)로부터의 칩이 함유된 절삭유를 여과시키도록 하는 필터링장치(20)가 구비되는데, 도 1B 에서 상기 필터링장치는 권취 로울러(21)에 감긴 페이퍼 필터(22)가 아이들러(23) 및 구동 로울러(24)를 거치게 되는데 상기 아이들러(23)와 구동 로울러(24) 사이의 필터 부분으로 칩이 함유된 절삭유가 회수용 펌프(18)에 의해 유입되면서 칩이 여과되어 메인탱크(10)로 순수한 절삭유만 포집된다. 한편, 상기 필터(22)의 여과능력이 저하되면 필터를 통과한 절삭유가 통과하지 못한 절삭유가 많게 되어 압력차가 발생하게 된다. 그 차이를 감지하여 사용한 필터(22)를 일정구간 밀어내어 새로운 부분으로 위치시키게끔 로울링시킨다.The auxiliary tank 14 is provided with a water level detection sensor 16 for detecting the level of the cutting oil introduced, and when the sensor 16 detects the upper limit water level, the recovery pump 18 is operated. The cutting oil of the auxiliary tank 14 is sent back to the main tank 10 by the recovery pump 18, while the flow path between the recovery pump 18 and the main tank 10 is in the auxiliary tank ( 14 is provided with a filtering device 20 for filtering the cutting oil containing chips from the filter device. In FIG. 1B, the filtering device has a paper filter 22 wound around a winding roller 21 with an idler 23 and a driving roller. The cutting fluid containing chips is introduced into the filter portion between the idler 23 and the driving roller 24 by the recovery pump 18, and the chips are filtered and the pure cutting oil is supplied to the main tank 10. Only is collected. On the other hand, when the filtration capacity of the filter 22 is lowered, there is a large amount of cutting oil that has not passed through the cutting oil that has passed through the filter, resulting in a pressure difference. By detecting the difference, the used filter 22 is pushed out for a certain period and rolled so as to be positioned as a new part.

그러나, 이와같은 종래의 필터링장치에서 여과의 능력이 저하된 필터로 절삭유가 다량으로 계속 회수되면 잘 여과되지 못하여 오버 플로어(over flow)현상이 발생되는 문제점이 발생되었고, 또한 여과되는 절삭유의 정도에 따라 10㎛, 25㎛, 50㎛, 100㎛ 등 여과정도를 다양하게 조정할 필요가 있을 때 대처하지 못하게 되는 문제점이 발생하였다.However, in the conventional filtering device, if a large amount of cutting oil continues to be recovered by the filter having reduced filtration ability, it may not be filtered well, resulting in an overflow phenomenon. Accordingly, there is a problem that can not cope when it is necessary to adjust the degree of filtration variously, such as 10㎛, 25㎛, 50㎛, 100㎛.

또한, 종래의 필터링구조는 복잡하게 구성되어 있기 때문에 설치비용이 상승되면서 생산성이 저하되는 문제점이 발생하였다.In addition, since the conventional filtering structure is complicated, there is a problem in that the productivity is reduced while the installation cost is increased.

따라서, 본 발명은 상기와 같은 제반문제를 해결하기 위해 안출된 것으로서 그 목적은 공작물의 가공을 위한 잘삭유가 칩(chip)을 함유한 상태로 회유되면서 걸르는 필터를 다양하게 적용시키도록 하고, 필터링을 위한 구조를 보다 간단하게 구성하도록 하는 머시닝 센터의 절삭유 필터링장치를 제공함에 있다.Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to apply various filters to filter while the cutting oil for the processing of the workpiece whilst containing a chip (chip), filtering It is to provide a coolant filtering device of a machining center to more simply configure the structure for.

본 발명의 구성은, 메인탱크의 절삭유가 머시닝 센터의 절삭부로 분사되면서 1차 집수되고, 집수된 절삭유의 만수위를 감지할 때 펌핑하여 필터링하고 다시 메인탱크로 유입시키며 순환하도록 하는 머시닝 센터의 필터링장치에 있어서,The configuration of the present invention, when the coolant of the main tank is injected into the cutting portion of the machining center is first collected, when detecting the full water level of the collected coolant pumping and filtering the filter back to the main tank to circulate and circulate again To

머시닝 센터(12)의 절삭부로 분사되는 절삭유를 1차로 집수하는 보조탱크(14)와 연결되는 봉형의 필터링 탱크(30)를 구비설치한다.It is provided with a rod-shaped filtering tank 30 connected to the auxiliary tank 14 for collecting the cutting oil injected into the cutting portion of the machining center 12 first.

상기 필터링 탱크(30)내에는 내향되는 돌출턱(32)이 환설되어 있으며, 그 돌출턱(32)에는 여과되는 절삭유의 정도에 따라 10㎛, 25㎛, 50㎛, 100㎛ 등 여과정도를 다양하게 조정할 필요가 있을 때 교체가 가능한 필터수단(34)이 개재된다.The projection jaw 32 is inwardly provided in the filtering tank 30, and the projection jaw 32 has various filtration degrees such as 10 μm, 25 μm, 50 μm, and 100 μm depending on the amount of cutting oil to be filtered. Interchangeable filter means 34 are interposed when it is necessary to make adjustments.

또한, 상기 필터링 탱크(30)의 외측으로는 탱크(30) 내부의 차압을 감지하고, 감지한 값을 작업자로 하여금 인지하도록 하는 차압감지센서(36)가 부설된다.In addition, the differential pressure detecting sensor 36 is installed outside the filtering tank 30 to detect the differential pressure inside the tank 30 and allow the operator to recognize the detected value.

상기 차압감지센서(36)는 필터수단(34)을 통과하지 못한 절삭유 압력과 필터수단(34)을 통과한 절삭유 압력을 설정압력과 비교하여 표시하는 감지수단이다.The differential pressure sensor 36 is a sensing means for displaying the cutting oil pressure that has not passed through the filter means 34 and the cutting oil pressure that has passed through the filter means 34 in comparison with the set pressure.

상기와 같이 구성된 본 발명의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the present invention configured as described above are as follows.

메인탱크(10)에서 펌핑된 절삭유가 머시닝센터(12)의 절삭부로 분사하게 되고, 공구대(도시안됨)에 의한 절삭작업으로 발생되는 칩이 절삭유에 함유된 상태에서 보조탱크(14)로 집수된다.Cutting oil pumped from the main tank 10 is injected into the cutting portion of the machining center 12, and the chips generated by the cutting operation by the tool stage (not shown) are collected in the auxiliary tank 14 while the cutting oil is contained in the cutting oil. do.

상기 보조탱크(14)는 내설된 수위감지센서(16)에 의해 그 양을 조절하게 되고, 조절된 양만큼 회수용 펌프(18)의 펌핑으로 인해 필터링장치(20)로 보내지게 된다. 여기까지의 순환과정은 종래와 동일하다.The auxiliary tank 14 is controlled by the built-in water level sensor 16, and is sent to the filtering device 20 due to the pumping of the recovery pump 18 by the adjusted amount. The circulation process up to this point is the same as before.

본 발명의 필터링장치는 필터링 탱크(30)를 의미하며, 상기 필터링 탱크(30)로 유입된 절삭유는 그 내부에 환설된 돌출턱(32)으로 얹혀지고 교환이 자유로운 필터수단(34)에 의해 칩이 걸르면서 순수한 절삭유만을 다시 메인탱크(10)로 환수시킨다.The filtering device of the present invention means a filtering tank 30, the cutting oil introduced into the filtering tank 30 is chipped by a filter means 34, which is mounted on the projection jaw (32) that is recirculated therein and is free to exchange. While filtering, only pure cutting oil is returned to the main tank 10 again.

그러나, 순환을 반복하는 과정에서 필터수단(34)의 여과능력이 저하되면 아무리 보조탱크(14)의 회수용 펌프(18)가 펌핑을 시키더라도 회수되는 절삭유량이 적어지게 되는데, 이를 차압감지센서(36)에서 감지하여 교환의 시기를 작업자로 하여금 인지되게 알려주게 된다. 본 발명의 필터수단(34)은 언제나 교체가능하게 구성되어 있기 때문에 필요에 의해 교환만 하면 되는 것이다.However, if the filtration capacity of the filter means 34 decreases in the course of repeating the circulation, no matter how much the recovery pump 18 of the auxiliary tank 14 pumps, the amount of cutting flow recovered is reduced. In step 36), the operator is informed of the timing of the exchange. Since the filter means 34 of the present invention is configured to be replaceable at all times, it is only necessary to replace the filter as necessary.

한편, 절삭유에서 함유되는 칩의 함유도에 따라 다양한 메쉬를 갖는 필터수단(34)을 사용할 수 있으므로 절삭유의 순환을 원활하게 할 수 있다.On the other hand, since the filter means 34 having various meshes can be used according to the degree of chip content contained in the cutting oil, it is possible to smooth the circulation of the cutting oil.

이상에서와 같은 본 발명을 필터링장치에 적용하게 되면, 필터수단이 교체가 자유롭게 구성되어 있을 뿐 아니라 필터링 정도에 따라 압력을 감지하여 교체시기를 작업자에게 인지시키게끔 구성되어 있기 때문에 절삭유가 보조탱크로부터 넘치는 현상을 방지하게 되고, 절삭유의 순환을 원활하게 할 수 있는 매우 유용한 효과가 발생된다.When the present invention is applied to the filtering device as described above, since the filter means is not only configured to be freely replaced but also configured to detect the pressure according to the degree of filtering, the operator knows the replacement time from the auxiliary tank. The overflow phenomenon is prevented, and a very useful effect of smoothing the circulation of the cutting oil is generated.
