Description

절삭유 공급 장치{Device for supplying cutting oil}[0001] The present invention relates to a device for supplying cutting oil,

본 발명의 일 실시예는 절삭유 공급 장치에 관한 것이다.One embodiment of the present invention relates to a coolant supply device.

일반적으로 CNC 선반과 같은 공작기계는 가공하고자 하는 공작물을 클램핑하여 고속으로 회전시키는 스핀들과, 상기 스핀들의 척에 클램핑된 공작물의 중심을 지지하여 고속회전을 돕는 심압대, 베드에 설치된 구동수단에 의해 가변하면서 공작물을 가공하는 터렛을 포함하는 공구대 등으로 구성된다.In general, a machine tool such as a CNC lathe includes a spindle for clamping and rotating a workpiece to be machined at a high speed, a tailstock for supporting a center of the workpiece clamped by the chuck of the spindle, And a tool base including a turret for processing the workpiece while varying the workpiece.

상기한 구성의 공작기계는, 공작물을 가공하는 경우에 공구와 그 공구에 의해 가공되는 공작물에 높은 열이 발생됨과 함께 가공 부산물인 절삭칩이 발생하게 된다.In the above-described machine tool, when machining a workpiece, high heat is generated in a tool and a workpiece processed by the tool, and a cutting chip, which is a by-product of machining, is generated.

상기한 열의 발생은 공구의 내구성에 악영향을 끼치고, 절삭칩의 잔류는 가공면의 정밀도에 악영향을 끼치므로 가공부위의 냉각과 절삭칩의 제거를 위하여 공작물의 가공부위로 일정압의 절삭유가 공급된다. 상기한 절삭유는 공작기계에 따라 다르지만 절삭유 공급장치에 의해 일정한 압력으로 분사된다.The generation of the above-described heat adversely affects the durability of the tool, and the residual of the cutting chip adversely affects the precision of the machined surface, so that a certain amount of cutting oil is supplied to the machined portion of the workpiece for cooling the machined portion and removing the cutting chip . The above-mentioned cutting oil varies depending on the machine tool, but is sprayed at a constant pressure by the coolant supply device.

하지만, 종래의 절삭유 공급장치에서는 펌프에서 토출된 절삭유가 On / Off 기능이 없어 항상 On인 상태를 유지한다. 또한, 절삭유가 연속으로 토출되고 있으므로 절삭유를 인접공구나 다른 부위로의 누유되는 사태를 방지하기 위해서는 부싱 부품이 터렛 디스크 회전면에 항상 밀착하고 있어야 한다. 밀착하는 힘은 스프링력에 의해 결정된다. 부싱과 터렛디스크가 항상 밀착된 상태를 유지하기 때문에 터렛 디스크가 인덱스(툴 교환)를 위하여 회전할 때 접촉면은 마찰이 발생하여 편마모 현상이 생길 수 있다. 이런 식으로 편마모가 발생하면 부싱 부품의 수명이 줄어들고 인접공구나 공구대 내부의 다른 부위로 절삭유 누유 현상도 발생하게 되는 문제점이 있다.However, in the conventional coolant supply device, the coolant discharged from the pump does not have an On / Off function and thus is always kept in the On state. In addition, since the cutting oil is continuously discharged, the bushing parts must always be in close contact with the turret disk rotation surface in order to prevent the cutting oil from leaking to the adjacent tool or other parts. The tightening force is determined by the spring force. Since the bushing and the turret disk are kept in close contact with each other, when the turret disk rotates for indexing (tool exchange), friction of the contact surface may occur, resulting in uneven wear. If the uniaxial abrasion occurs in this way, the life of the bushing part is shortened, and there is a problem that the cutting oil leaks to other parts of the adjacent tool or the tool base.

It should be interpreted in accordance with the meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined.

도 1은 본 발명의 일 실시예에 따른 절삭유 공급 장치를 포함한 공구대를 도시한 단면도이고, 도 2 및 도 3은 본 발명의 일 실시예에 따른 절삭유 공급 장치의 동작을 설명하기 위한 동작도이다.FIG. 1 is a sectional view showing a tool holder including a coolant supply device according to an embodiment of the present invention, and FIGS. 2 and 3 are operation diagrams for explaining the operation of a coolant supply device according to an embodiment of the present invention .

도 1 내지 도 3에 도시된 바와 같이, 본 발명에 따른 절삭유 공급 장치는 공구대 몸체(10), 절삭유로(20), 클램핑 유닛(30), 개폐 부재(40), 부싱(50), 스프링(60) 및 터렛 디스크(70)를 포함한다.1 to 3, the cutting oil supply device according to the present invention includes a tool body 10, a cutting oil passage 20, a clamping unit 30, an opening and closing member 40, a bushing 50, (60) and turret disk (70).

여기서, 도 1에는 설명의 편의를 위하여, 공구대의 구성 중 본 발명에 따른 절삭유 공급 장치의 필요 구성에만 도면 부호를 기재하였고, 이하에서는 필요 구성만을 설명하고, 공구대의 공지된 구성에 대해서는 자세한 설명은 생략한다.Here, for convenience of explanation, only the necessary components of the coolant supply device according to the present invention among the components of the tool stand are denoted by the same reference numerals in FIG. 1, and only the necessary components are described below. It is omitted.

상기 절삭유로(20)는 공구대 몸체(10)를 관통하도록 내부에 형성된 것으로, 절삭유(도 2 및 도 3의 화살표 참조)의 이동 경로를 제공한다. 여기서, 상기 절삭유는 기름, 기름과 물의 혼합물, 페이스트, 젤, 미스트 등으로 구성될 수 있으나, 본 발명에서 상기 절삭유의 종류를 한정하는 것은 아니다.The cutting oil passage 20 is formed internally to penetrate the tool rest body 10 and provides a movement path of the cutting oil (see the arrows in FIGS. 2 and 3). Here, the cutting oil may be composed of a mixture of oil, oil and water, paste, gel, and mist, but the kind of the cutting oil is not limited in the present invention.

상기 절삭유로(20)의 출구 측에서는 공작물의 가공을 위해 회전 가능하도록 설치된 터렛 디스크(70)가 배치되어 있다. 즉, 절삭유는 상기 절삭유로(20)를 따라 터렛 디스크(70)로 배출되며, 가공 공정에 사용된다. On the outlet side of the cutting oil passage 20, a turret disk 70 rotatably installed for machining a workpiece is disposed. That is, the cutting oil is discharged to the turret disk 70 along the cutting oil passage 20, and is used in the machining process.

여기서, 도 2를 참조하면, 절삭유로(20)와 터렛 디스크(70)의 연결부에는 부싱(50) 및 스프링(60)이 배치된다. 절삭유로(20)가 개방되었을 경우, 절삭유는 절삭유로(20)를 따라 흐르며, 절삭유로(20) 끝단에 설치된 부싱(50)을 가압하게 된다. 이로써, 부싱(50)은 탄성의 스프링(60)을 밀어내게 되고, 절삭유의 토출 채널이 형성된다.Referring to FIG. 2, a bushing 50 and a spring 60 are disposed at a connection portion between the cutting oil passage 20 and the turret disk 70. When the cutting oil passage 20 is opened, the cutting oil flows along the cutting oil passage 20 and presses the bushing 50 installed at the end of the cutting oil passage 20. Thereby, the bushing 50 pushes the elastic spring 60, and the discharge channel of the coolant is formed.

상기 클램핑 유닛(30)은 공구대 몸체(10)의 일측에 설치되며, 터렛 디스크(70)를 공구대 몸체(10)에 클램핑하는 역할을 수행한다. 여기서, 상기 클램핑 유닛(30)은 제1커빅 커플링(31), 제2커빅 커플링(32) 및 제3커빅 커플링(33)의 3-피스 커빅 커플링으로 형성된다.The clamping unit 30 is installed at one side of the tool rest body 10 and serves to clamp the turret disk 70 to the tool rest body 10. Here, the clamping unit 30 is formed by a three-piece conic coupling of a first conic coupling 31, a second conic coupling 32 and a third conic coupling 33.

상기 개폐 부재(40)는 절삭유로(20)를 관통하도록 설치되며, 절삭유로(20)의 수직인 방향으로 배치된다. 또한, 상기 개폐 부재(40)의 일단이 상기 클램핑 유닛(30)에 연결되어 있어, 상기 클램핑 유닛(30)의 클램핑 동작에 의해 전, 후 방향으로 이동하는 것이 가능하다. 여기서, 상기 개폐 부재(40)의 전방향은 클램핑 유닛(30)을 향한 방향이고, 상기 개폐 부재(40)의 후 방향은 절삭유로(20)를 향한 방향이라 지칭한다.The opening and closing member 40 is installed to pass through the cutting oil passage 20 and is disposed in a direction perpendicular to the cutting oil passage 20. One end of the opening and closing member 40 is connected to the clamping unit 30 so that the clamping unit 30 can be moved forward and backward by the clamping operation. Here, the forward direction of the opening and closing member 40 is a direction toward the clamping unit 30, and the rear direction of the opening and closing member 40 is referred to as a direction toward the cutting oil passage 20.

이하에서는 도 2 및 도 3을 참조하여, 본 발명의 일 실시예에 따른 절삭유 공급 장치의 동작을 설명한다.Hereinafter, the operation of the coolant supply apparatus according to one embodiment of the present invention will be described with reference to FIGS. 2 and 3. FIG.

여기서, 자세히는 도 2는 절삭유로(20)가 개방되었을 경우의 절삭유의 흐름을 도시한 단면도이며, 도 3은 절삭유로(20)가 폐쇄되었을 경우의 절삭유의 흐름을 도시한 단면도이다.2 is a sectional view showing the flow of cutting oil when the cutting oil passage 20 is opened, and FIG. 3 is a sectional view showing the flow of the cutting oil when the cutting oil passage 20 is closed.

우선, 도 2를 참조하여 절삭유로(20)가 개방되는 동작을 설명하면, 공작물 가공 시 공작대 본체(10)의 일측에 설치된 클램핑 유닛(30)은 터렛 디스크(70)를 클램핑 하게 된다. 여기서, 클램핑 유닛(30)은 터렛 디스크(70)를 클램핑 시 절삭유로(20)를 관통하도록 배치된 개폐 부재(40)를 절삭유로(20) 측(전 방향)으로 이동시킨다.Referring to FIG. 2, the operation of opening the cutting oil passage 20 will be described. The clamping unit 30 installed on one side of the workpiece body 10 clamps the turret disk 70 when the workpiece is machined. Here, the clamping unit 30 moves the opening / closing member 40 arranged to pass through the cutting oil passage 20 on the cutting oil passage 20 side (forward direction) when the turret disk 70 is clamped.

상기 개폐 부재(40)에는 절삭유로(20)의 직경에 대응되는 크기로 형성되는 관통홀(41)이 형성된다. 여기서, 상기 개폐 부재(40)는 클램핑 유닛(30)에 의해 절삭유로(20) 측으로 이동될 경우, 상기 관통홀(41)이 절삭유로(20)에 대응되는 위치에 배치된다. 따라서, 절삭유로(20)는 개방되고, 상기 관통홀(41)을 통해 절삭유의 경로가 제공된다. 즉, 도 2의 화살표와 같이 절삭유는 절삭유로(20)의 끝단에 설치된 부싱(50)까지 도달한다.The opening and closing member 40 is formed with a through hole 41 having a size corresponding to the diameter of the cutting oil passage 20. The through hole 41 is disposed at a position corresponding to the cutting oil passage 20 when the opening and closing member 40 is moved toward the cutting oil passage 20 by the clamping unit 30. [ Thus, the cutting oil passage 20 is opened, and the path of the coolant is provided through the through hole 41. [ 2, the cutting oil reaches the bushing 50 provided at the end of the cutting oil passage 20. [

즉, 상기 개폐 부재(40)는 절삭유로(20)의 개폐를 담당하여 공작물 가공 시에만 절삭유가 부싱(50)을 가압하고, 또한, 터렛 디스크(70)를 통해 토출되도록 한다. 물론, 밀려난 부싱(50)은 터렛 디스크(70)에 밀착하게 된다.That is, the opening / closing member 40 is responsible for opening and closing the cutting oil passage 20, so that the cutting oil presses the bushing 50 only when the workpiece is machined, and is discharged through the turret disk 70. Of course, the pushing bushing 50 is brought into close contact with the turret disk 70.

다음은, 도 3을 참조하여 절삭유로(20)가 폐쇄되는 동작을 설명하면, 공작물 비 가공 시 공작대 본체(10)의 일측에 설치된 클램핑 유닛(30)은 언클램핑 상태에 놓인다. 여기서, 클램핑 유닛(30)은 언클램핑 상태 시 절삭유로(20)를 관통하도록 배치된 개폐 부재(40)를 클램핑 유닛(30) 측(후 방향)으로 이동시킨다.Next, referring to Fig. 3, the operation of closing the cutting oil passage 20 will be described. When the workpiece is not machined, the clamping unit 30 provided on one side of the workpiece machine body 10 is placed in the unclamping state. Here, the clamping unit 30 moves the opening / closing member 40 arranged to pass through the cutting oil passage 20 in the unclamping state to the clamping unit 30 side (backward direction).

따라서, 상기 개폐 부재(40)가 클램핑 유닛(30) 측으로 이동될 경우, 상기 관통홀(41)이 절삭유로(20)에 대응되는 위치에서 벗어나도록 배치된다. 따라서, 절삭유로(20)는 개폐 부재(40)의 일면에 의해 폐쇄되고, 절삭유의 경로는 폐쇄된다. 즉, 도 3의 화살표와 같이 절삭유는 절삭유로(20) 내에서 개폐 부재(40)하단으로는 흐르지 못한다.
Therefore, when the opening and closing member 40 is moved to the side of the clamping unit 30, the through hole 41 is disposed so as to deviate from the position corresponding to the cutting oil passage 20. Thus, the cutting oil passage 20 is closed by one surface of the opening and closing member 40, and the path of the cutting oil is closed. 3, the cutting oil can not flow to the lower end of the opening / closing member 40 in the cutting oil passage 20. [

이상에서 설명한 것은 본 발명에 따른 절삭유 공급 장치를 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 발명은 상기한 실시예에 한정되지 않고, 이하의 특허청구범위에서 청구하는 바와 같이 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능한 범위까지 본 발명의 기술적 정신이 있다고 할 것이다.It is to be understood that the present invention is not limited to the above-described embodiment, and that various modifications and changes may be made without departing from the scope of the present invention as defined in the appended claims. 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.
