Description

터렛공구대의 절삭유 공급장치 {Supplyung device for cutting oil of the turret}Cutting oil feeder for turret tool {Supplyung device for cutting oil of the turret}

본 발명은 터렛공구대의 절삭유 공급장치에 관한 것으로서, 보다 상세하게는 터렛에 설치되어 있는 절삭가공용 공구에 절삭유를 공급하기 위한 터렛공구대의 절삭유 공급장치에 관한 것이다.
The present invention relates to a cutting oil supply device for a turret tool, and more particularly, to a cutting oil supply device for supplying cutting oil to a cutting tool installed in a turret.

이하, 도면을 참조하여 종래의 터렛공구대의 절삭유 공급장치에 대해 살펴본다.Hereinafter, a cutting oil supply device of a conventional turret tool tool will be described with reference to the accompanying drawings.

도 1에 도시된 바와 같이, 종래의 터렛공구대의 절삭유 공급장치는 회전하는 디스크(2) 내에 다수의 유로가 형성되고, 회전하지 않는 아답터(4)에는 하나의 유로(4a)가 형성된다. As shown in FIG. 1, the cutting oil supply device of the conventional turret tool bench has a plurality of flow paths formed in the rotating disk 2, and one flow path 4a is formed in the adapter 4 which does not rotate.

여기서, 상기 디스크(2) 내의 다수의 유로는 하나의 활성화된 유로(2a)와 다수의 활성화되지 않은 유로(도시 생략)로 나뉜다. 즉, 정상적으로 절삭유가 공급되어야 되는 유로가 활성화된 유로(2a)이며, 절삭유 공급이 필요하지 않은 유로가 활성화되지 않은 유로이다.Here, the plurality of flow paths in the disc 2 are divided into one activated flow path 2a and a plurality of unactivated flow paths (not shown). That is, the flow path 2a in which the cutting oil is to be supplied normally is activated, and the flow path in which the cutting oil supply is not required is the flow path in which it is not activated.

또한, 상기 아답터(4)의 유로(4a) 끝단과 상기 디스크(2)와의 사이에는 회전을 위한 틈새가 존재하며, 절삭유 라인 상의 누유를 방지하기 위해 부싱(11)이 조립된다. 이 부싱(11)은 상기 디스크(2)가 고정 또는 회전시에 절삭유가 틈새로 누유되는 것을 효과적으로 방지하기 위해 스프링(12)에 의해 상기 디스크(2) 면에 밀착되게 설치된다.In addition, a gap for rotation exists between the end of the flow passage 4a of the adapter 4 and the disk 2, and the bushing 11 is assembled to prevent leakage on the cutting oil line. The bushing 11 is installed in close contact with the disk 2 surface by a spring 12 in order to effectively prevent leakage of cutting oil into a gap when the disk 2 is fixed or rotated.

상기 디스크(2)에는 피삭재를 가공하기 위한 다양한 절삭공구(도시 생략)가 장착되며, 상기 절삭공구 중에서 바이트(bite)가 피삭재를 가공할 시에는 다양한 칩이 발생하며 공구, 칩 및 피삭재에는 열이 발생하게 되는데, 전단면에서 전단변형을 일으킬 때의 칩의 변형, 공구 표면의 절삭에 의한 마찰, 공구 선단이 절삭표면을 통과할 때 생기는 마찰 등으로 인해 열이 발생하게 된다.The disk 2 is equipped with a variety of cutting tools (not shown) for processing the workpiece, a variety of chips are generated when the bite of the cutting tools to process the workpiece, and the heat to the tool, chip and workpiece The heat is generated due to the chip deformation, the friction caused by the cutting of the tool surface, the friction generated when the tip of the tool passes through the cutting surface, and the like.

이때 발생된 열의 일부는 칩에 의해 제거되고 일부는 공구에 전달되며, 나머지 일부는 피삭재의 내부로 들어가서 일정한 양의 절삭부 온도를 높여준다. 이로 인해 구성인선(built-up edge)이 생겨 가공면을 거칠게 하고 공구의 마모를 크게 하여 공구수명을 단축시킨다.Some of the heat generated is removed by the chip, some is transferred to the tool, and some of the heat enters the workpiece to raise the amount of cutting temperature. This creates a built-up edge, which roughens the machining surface and increases the wear of the tool, thereby shortening the tool life.

따라서, 절삭가공에서는 날끝을 냉각하고 절삭열에 의한 날끝의 경도가 감소되는 것을 방지하며, 피삭재를 냉각하고 온도상승에 의한 치수정밀도의 저하를 방지하며, 가공된 칩의 흐름(chip flow)을 도와서 절삭작용을 용이하게 하기 위해 절삭유의 사용이 필수이다.Therefore, in the cutting process, the cutting edge is cooled and the hardness of the cutting edge is prevented from being reduced, the workpiece is cooled, the dimensional precision is prevented from rising due to the temperature rise, and the chip flow is helped by cutting. The use of coolant is essential to facilitate the action.

특히, 자동선반, 머시닝센터 등에 사용되는 터렛공구대에는 필수적으로 절삭유 공급장치를 포함하고 있으며, 제품의 고급화를 위해 보다 빠른 냉각과 보다 원활한 절삭유의 공급을 위해 점차 고압 절삭유 공급장치가 요구되는 실정이다.In particular, turret tools used in automatic lathes, machining centers, etc. essentially include a coolant supply device, and a high pressure coolant supply device is increasingly required for faster cooling and smoother coolant supply for high quality products. .

이처럼 종래의 절삭유 공급장치는 절삭가공시 항상 절삭유 공급이 가능한 상태로 되어 있는 절삭유로로 인해 절삭가공을 할 때뿐만 아니라, 공구교환을 위해 디스크(2)가 회전할 때에도 절삭유가 공급된다.As described above, the conventional cutting oil supply device is supplied with cutting oil not only when cutting, but also when the disk 2 rotates for tool change, due to the cutting oil path which is always in a state where cutting oil can be supplied during cutting.

그러나, 이와 같은 종래의 터렛공구대의 절삭유 공급장치는 절삭유압이 고압일 경우, 절삭유가 스프링(12)의 탄성력을 이기고 부싱(11)과 디스크(2) 사이의 틈새로 침투되어 누유되는 문제가 발생된다.
However, the cutting oil supply device of such a conventional turret tool, when the cutting hydraulic pressure is high pressure, the cutting oil is overcome the elastic force of the spring 12 and the oil leaks into the gap between the bushing 11 and the disk (2) occurs do.

본 발명은 상기한 문제점을 해결하기 위하여 창출된 것으로서, 고압의 절삭유가 공급될 시에도 부싱과 디스크 사이의 틈새를 방지할 수 있는 터렛공구대의 절삭유 공급장치를 제공하는데 그 목적이 있다.

Therefore, It should be understood that various equivalents and modifications may be present.

도 2 및 도 3에 도시된 바와 같이, 본 발명의 일 실시예에 따른 터렛공구대의 절삭유 공급장치는 공구에 회전력을 전달하는 메인모터(도시 생략)와, 복수의 공구홀더(3)를 회전시키기 위한 서보모터(도시 생략)와, 상기 복수의 공구홀더(3)가 장착되며 내부에는 상기 다수의 공구홀더(3)와 대응하는 절삭유 공급용 유로(18a)가 각각 형성되는 디스크(18)와, 상기 디스크(18)의 어느 하나의 유로와 선택적으로 대응하는 단일의 절삭유 공급용 유로(17a)가 형성되며 상기 단일의 유로(17a)와 연결되는 유압라인(14)이 연통형성되는 아답터(17)와, 상기 아답터(17)의 유로(17a) 상에 상기 디스크(18)의 일면과 밀착되게 설치되는 부싱(13)을 포함하여 구성된다.As shown in Figure 2 and 3, the cutting oil supply device of the turret tool according to an embodiment of the present invention is to rotate the main motor (not shown) and a plurality of tool holder (3) for transmitting a rotational force to the tool A servo motor (not shown), a plurality of tool holders 3 mounted therein, and a disk 18 having a plurality of tool holders 3 and cutting oil supply flow paths 18a respectively formed therein; An adapter 17 in which a single cutting oil supply flow passage 17a, which selectively corresponds to any one flow path of the disk 18, is formed and a hydraulic line 14 connected to the single flow passage 17a is formed in communication. And a bushing 13 mounted on the flow path 17a of the adapter 17 to be in close contact with one surface of the disk 18.

상기 아답터(17)는 고정되며, 통상 상기 유로(17a)가 상기 디스크(18)의 유로(18a)와 서로 연통될 때에 절삭유가 공급되게 된다.The adapter 17 is fixed, and cutting oil is supplied when the flow path 17a communicates with the flow path 18a of the disk 18.

상기 부싱(13)과 상기 디스크(18)의 일면 사이에는 수지 재질의 개스킷(15)이 설치될 수 있다. 이 개스킷(15)은 상기 부싱(13)을 탄성 지지할 수 있는 재질이면 다양하게 선택 가능하다.A resin gasket 15 may be installed between the bushing 13 and one surface of the disk 18. The gasket 15 may be variously selected as long as it is a material capable of elastically supporting the bushing 13.

한편, 상기 부싱(13)은 상기 개시킷(15)과 접촉하는 밀착부(13-1)와, 상기 밀착부(13-1)와 단차지게 일체로 설치되며 상기 아답터(17)의 유압라인(14)이 연통되는 공간부(13a)를 형성하는 연장부(13-2)로 이루어진다.On the other hand, the bushing 13 is installed integrally with the contact portion 13-1 and the contact portion 13-1 in contact with the start kit 15, the hydraulic line of the adapter 17 ( It consists of the extension part 13-2 which forms the space part 13a which 14 is communicated with.

또한, 본 발명은 상기 디스크(18)의 일면에 형성되어 누유를 방지하기 위한 쿼드링(16)을 더 포함할 수 있다. 즉, 상기 아답터(17)의 유로(17a)로 절삭유가 계속하여 공급되므로 아답터(17)의 외면을 따라 절삭유가 흘러 활성화되지 않은 공구 쪽으로도 절삭유가 분출될 수 있는데 이를 상기한 쿼드링(16)으로서 새는 것을 방지할 수 있다.In addition, the present invention may further include a quad ring 16 formed on one surface of the disk 18 to prevent leakage. That is, since the coolant is continuously supplied to the flow path 17a of the adapter 17, the coolant flows along the outer surface of the adapter 17 so that the coolant may be ejected toward the tool that is not activated. As a result, leakage can be prevented.

본 발명은 커빅커플링들(5)(6)(7)의 결합 유무에 따라 상기한 디스크(18)가 회전 가능하거나 회전 불가능하게 되는데, 상기 피스톤커빅커플링(5)이 도면의 우측 방향으로 이동하게 되면 고정커빅커플링(7) 및 선회커빅커플링(6)과 결합되게 되어 디스크(18)가 회전되지 않는 상태가 되며, 반대로 피스톤커빅커플링(5)이 도면의 좌측 방향으로 이동하게 되면 고정커빅커플링(7) 및 선회커빅커플링(6)과 결합이 해제되어 디스크(18)가 회전 가능한 상태가 된다.According to the present invention, the above-mentioned disk 18 is rotatable or non-rotable depending on whether the cubic couplings 5, 6, and 7 are coupled, and the piston cubic coupling 5 is moved in the right direction of the drawing. When it moves, the fixed curvature coupling 7 and the turning curvature coupling 6 are coupled to each other so that the disk 18 is not rotated. On the contrary, the piston curvature coupling 5 moves in the left direction of the drawing. In this case, the coupling with the fixed cubic coupling 7 and the turning cubic coupling 6 is released, and the disk 18 is rotatable.

즉, 커빅커플링들(5)(6)(7) 간의 결합이 해제된 상태는 디스크(18)의 회전이 가능한 상태이므로 공구교환이 이루어지고, 반대로 커빅커플링들(5)(6)(7) 간 결합이 이루어진 상태에서는 디스크(18)의 회전이 불가능한 상태이므로 절삭가공이 이루어지는 상태이다.That is, the state in which the coupling between the cubic couplings 5, 6, 7 is released is a state in which the rotation of the disk 18 is possible, so that a tool change is performed. 7) In the state where the coupling is made, it is a state that the cutting process is performed because the disk 18 is impossible to rotate.

상기 피스톤커빅커플링(5)을 이동시키는 것은 클램프 유압공급유로(도시 생략) 및 언클램프 유압공급유로(도시 생략)에 유압을 인가함으로써 오일이 입출되어 구동시켜주게 된다. 즉, 클램프 유압공급유로로 유압이 충전되면 피스톤커빅커플링(5)이 도면의 우측 방향으로 이동하여 커빅커플링들(5)(6)(7) 간에 결합된 상태가 되며, 반대로 언클램프 유압공급유로로 유압이 충전되면 피스톤커빅커플링(5)이 도면의 우측 방향으로 이동하여 커빅커플링들(5)(6)(7) 간에 결합이 해제된 상태가 된다.In order to move the piston cubic coupling 5, oil is extracted and driven by applying hydraulic pressure to the clamp hydraulic supply passage (not shown) and the unclamp hydraulic supply passage (not shown). That is, when the hydraulic pressure is filled into the clamp hydraulic supply flow path, the piston cubic coupling 5 moves in the right direction of the drawing to be coupled between the cubic couplings 5, 6, and 7, and vice versa. When the hydraulic pressure is filled into the supply passage, the piston cubic coupling 5 moves in the right direction of the drawing, and the coupling between the cubic couplings 5, 6 and 7 is released.

또한, 아답터(17)에 형성된 유압라인(14)은 클램프 유압공급유로와 연통되어 상기 커빅커플링들(5)(6)(7) 간의 결합을 위한 클램프 시의 유압이 공급된다.In addition, the hydraulic line 14 formed in the adapter 17 is in communication with the clamp hydraulic supply flow path is supplied with the hydraulic pressure at the time of the clamp for coupling between the cubic couplings (5) 6 (7).

따라서, 본 발명의 터렛공구대의 절삭유 공급장치에 의하면, 절삭유압이 고압일 경우에도 클램프 시의 압력을 아답터(17)에 연통 형성된 유압라인(14)을 통해 공간부(13a)로 제공하여 부싱(13)과 디스크(18) 사이에 틈새를 방지하여 고압의 절삭유가 누유되는 것을 차단할 수 있게 된다.Therefore, according to the cutting oil supply apparatus of the turret tool according to the present invention, even when the cutting hydraulic pressure is a high pressure, the pressure at the time of the clamp is provided to the space portion 13a through the hydraulic line 14 formed in communication with the adapter 17 to the bushing ( It is possible to prevent the leakage of high-pressure cutting oil by preventing the gap between the 13) and the disk 18.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나 이에 한정되지 않으며, 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술 사상과 아래에 기재될 청구범위의 균등범위 내에서 다양한 수정 및 변형 가능함은 물론이다.While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It is to be understood that various changes and modifications may be made without departing from the scope of the present invention.
