In particular, the present invention provides a distribution block having a spray nozzle connected to a liftable main shaft side and through the distribution block. The present invention relates to an air / cutting oil injector of a machining center that selectively supplies and sprays air by a hydraulic circuit to effectively remove the cutting chips of the workpiece and simplify the injector regardless of the shape and size of the workpiece. .
머시닝센터와 같은 공작기계에 있어서 테이블 상면에 재치된 공작물을 가공하다 보면 절삭칩이 발생되고, 이러한 절삭칩을 제거하기 위해서는 가공중이나 가공완료후 공기노즐로부터 압축된 공기를 공작물의 가공면으로 분사시키게 되는데, 종래에는 제2도에 도시한 바와 같이 테이블(10)의 후방측에 스플래시 가드(12)가 설치되고, 주축대(14)가 설치되는 컬럼(16)의 일측인 상기 스플래시 가드(12)의 상단에 공압실린더(20)가 설치되고, 이 공압실린더(20)에 분배블록(22)이 연결되어 이 공압실린더(20)의 로드를 따라 승강이동 가능하고, 이 분배블록(22)에 다수개의 분사노즐(24)이 접속되고, 상기 공압실린더(20)는 공압원(25)에서 토출되는 압축공기의 방향을 절환시키는 실린더작동용 솔레노이드밸브(26)와 연결되고 또 상기 분배블록(22)은 같은 공압언(25)에서 토출되는 압축공기의 흐름을 개폐시키는 공기개폐용 솔레노이드밸브(28)에 연결되어 있는 구조로 되어 있다.In a machine tool such as a machining center, cutting chips are generated when machining the workpiece placed on the upper surface of the table.In order to remove the cutting chips, compressed air is injected from the air nozzle to the workpiece surface during or after machining. Conventionally, as shown in FIG. 2, the splash guard 12 is installed at the rear side of the table 10, and the splash guard 12, which is one side of the column 16 on which the headstock 14 is installed, is provided. Pneumatic cylinder 20 is installed at the top of the distribution block 22 is connected to the pneumatic cylinder 20 is movable up and down along the rod of the pneumatic cylinder 20, a plurality of the distribution block 22 Two injection nozzles 24 are connected, and the pneumatic cylinder 20 is connected to a solenoid valve 26 for cylinder operation for switching the direction of the compressed air discharged from the pneumatic source 25 and the distribution block 22 In the same pneumatic language (25) It has a structure connected to the air opening and closing solenoid valve 28 for opening and closing the flow of compressed air discharged.
미설명부호 M1은 테이블구동용 이송모터; M2는 주축대구동용 이송모터; S1,S2는 이송스크류이다.Reference numeral M1 denotes a transfer motor for driving a table; M2 is the feed motor for the main shaft drive; S1 and S2 are transfer screws.
이와 같이 구성된 종래의 머시닝 센터의 공기분사장치는 실린더작동용 솔레노이드밸브(26)가 전기적인 온/오프 제어신호에 의해 절환되면 공압원(25)에서 토출되는 압축공기의 흐름방향이 바뀜에 따라 공압실린더(20)의 로드가 상하로 이동하면서 분배블록(22)이 함께 상하이동하게 된다.When the air injection device of the conventional machining center configured as described above is switched by the solenoid valve 26 for cylinder operation by the electric on / off control signal, the pneumatic pressure is changed as the flow direction of the compressed air discharged from the pneumatic source 25 changes. As the rod of the cylinder 20 moves up and down, the distribution block 22 moves together.
이때 공기개폐용 솔레노이드밸브(28)의 절환위치에 따라 상기 분배블록(22)에 접속된 분사노즐(24)을 통해 압축공기가 분사된다.At this time, the compressed air is injected through the injection nozzle 24 connected to the distribution block 22 according to the switching position of the air opening and closing solenoid valve 28.
그러나 이같이 상기 공기실린더(20)의 로드가 제한된 행정거리 만큼만 이동가능하므로 분사노즐(24)의 이동위치가 제한을 받게되고 특히 가공공작물의 높이가 작을 경우에는, 공압실린더(20)의 로드가 최하부로 작동하여도 분사노즐(24)을 통한 분사압력이 가공공작물의 표면에 미치지 못하므로 사용의 효과가 없게될 뿐만 아니라, 다시 공압실린더(20)의 위치를 변경해야 하는 불편이 따르게 된다.However, since the rod of the air cylinder 20 can be moved only by a limited stroke distance, the movement position of the injection nozzle 24 is limited, especially when the height of the workpiece is small, the rod of the pneumatic cylinder 20 is the lowest. Even if it is operated as the injection pressure through the injection nozzle 24 does not reach the surface of the workpiece, not only does not have an effect of use, but also has the inconvenience of changing the position of the pneumatic cylinder 20 again.

In accordance with the rotation of the feed screw S2, a distribution block 40 having a spindle head 14 which is movable and having a plurality of lubricating oil injection nozzles 30 is installed. In the machining center in which the cutting oil supply pipe 51 connected to the cutting oil source 50 is provided, the T-type branch pipe 52 is connected to the middle of the cutting oil supply pipe 51, and the branch pipe ( An air backflow prevention check valve 54 is provided between the first inlet side 51a and the cutting oil source 50 of 52, and at the same time, the cutting flow backflow is between the second inlet side 52b and the pneumatic source 25. Prevent check valve 55 and the air opening and closing solenoid valve 28, but the cutting flow check valve (55) for air opening and closing solenoid It is a configuration hayeoseo installed on the exit side of the de valve 28.
이와 같이 구성된 본 발명의 작용효과를 살펴보면 다음과 같다.Looking at the effects of the present invention configured as described above are as follows.
제1도에 도시한 바와 같이 테이블(10)의 상면에 재치된 공작물(P)은 가공 도중 또는 가공완료 후 미리 입력된 프로그램의 지령에 따라 테이블구동용 이송 모터(M1)의 출력축과 연결된 이송스크류(S1)가 회전함에 따라 테이블(10)이 이송되어 공작물(P)이 분사노즐(30)의 직하방의 위치에 도달하게 되고, 동시에 주축대 구동용 이송모터(M2)와 직결된 이송스크류(S2)의 회전에 따라 주축대(14)가 일정위치 만큼 수직하강하고 동시에 주축대(14)에 결합되어 있는 분배블록(40)이 함께 하강하여 분사노즐(30)이 공작물(P)의 상면과 근접하게 된다. 이후 지정된 프로그램의 명령에 의해 공기개폐용 솔레노이드밸브(28)가 도면에서 좌측으로 절환되면 공압원(25)에서 토출되는 압축공기는 열려진 공기개폐용 솔레노이드밸브(28)를 거쳐 절삭유역류방지용 체크밸브(55)를 통하고 분기관(52)에서 분기되어 공급배관(51)을 따라 분배블록(40)에 설치된 각 분사노즐(30)로 분배되고, 이 분사노즐(30)을 통하여 압축공기가 공작물(P)의 표면을 향하여 분사된다.As shown in FIG. 1, the workpiece P placed on the upper surface of the table 10 is connected to an output shaft of the table driving feed motor M1 according to a program command input in advance during or after machining. As S1 rotates, the table 10 is conveyed so that the work P reaches a position directly below the injection nozzle 30, and at the same time, the feed screw S2 directly connected to the feedstock driving motor M2 for the headstock drive. In accordance with the rotation of the spindle head 14 is vertically lowered by a predetermined position and at the same time the distribution block 40 coupled to the spindle head 14 is lowered together, the injection nozzle 30 is close to the upper surface of the workpiece (P) Done. Thereafter, when the air opening / closing solenoid valve 28 is switched to the left in the drawing by the command of the designated program, the compressed air discharged from the pneumatic source 25 passes through the open air opening / closing solenoid valve 28 to check the cutting flow flow. 55 through the branch pipe 52 and distributed to the respective injection nozzles 30 installed in the distribution block 40 along the supply pipe 51, and the compressed air through the injection nozzle 30 to the workpiece ( Sprayed toward the surface of P).
이때 공기역류방지용 체크밸브(54)는 절삭유역류방지용 체크밸브(55)를 통과한 공기압력이 절삭유원(50)에 작용하는 것을 막게 된다.At this time, the air backflow prevention check valve 54 prevents the air pressure passing through the cutting backflow prevention check valve 55 from acting on the cutting oil source 50.
따라서 공작물의 형태에 따라 높이가 작더라도 주축대(14)를 필요한 만큼만 더 하강시키면 공작물(P)의 표면에 가까이 접근시켜 압축공기의 칩제거할 분사력이 효과적으로 미치게 할 수 있는 것이다.Therefore, even if the height is small according to the shape of the workpiece, if the main shaft 14 is lowered by only as much as necessary to approach the surface of the workpiece (P) close to it can effectively effect the blowing force to remove the chip of the compressed air.
한편, 공작물(P)에 절삭유가 공급되기 위해서는 공기개폐용 솔레노이드밸브(28)가 오프된 상태에서 절삭유 펌프(도시안됨)가 작동을 개시하면 절삭유원(50)으로부터 토출되는 절삭유는 공기역류방지용 체크밸브(54)를 통과하여 분기관(52)의 일측에 연결된 절삭유역류방지용 체크밸브(55)에 차단되고 동시에 공급배관(51)을 지나 분배블록(40)에 설치된 분사노즐(30)로 절삭유가 분사된다.On the other hand, in order to supply the cutting oil to the workpiece P, the cutting oil discharged from the cutting oil source 50 is checked for preventing air flow back when the cutting oil pump (not shown) starts to operate with the air-opening solenoid valve 28 turned off. Cutting oil flows to the injection nozzle 30 installed in the distribution block 40 by passing through the valve 54 and blocked by the cutting flow check valve 55 connected to one side of the branch pipe 52 and passing through the supply pipe 51. Sprayed.
이와 같이 본 발명에 의하면 분사노즐이 연결된 분배블록에 하나의 공급 배관을 연결시켜 절삭유와 압축공기를 선택적으로 공급시키고, 이 분배블록을 승강이동가능한 주축대에 설치시킴으로써 공작물의 크기 즉 높이의 변화에 대응되게 분사노즐을 공작물에 가까이 접근시킬 수가 있어 효과적인 절삭칩제거 및 청소를 수행할 수 있을 뿐만 아니라 절삭유공급을 공용으로 수행할 수 있어 분사장치의 단순화를 꾀할 수 있는 장점이 있다.As described above, according to the present invention, one supply pipe is connected to the distribution block to which the injection nozzle is connected to selectively supply cutting oil and compressed air, and the distribution block is installed on the movable headstock for lifting and lowering to change the size or height of the workpiece. Correspondingly, the injection nozzle can be approached close to the workpiece to effectively remove the cutting chips and to clean, as well as to supply the cutting oil in common, thereby simplifying the injection device.
