이때, 상기 공급/배출홀(41)에 연결되는 튜브(s1)는 기계장치(100)와 연결되면서, 상기 기계장치(100)는 상기 전극(30)으로 방전액을 공급함은 물론, 방전가공 시 발생하는 유해가스를 상기 공급/배출홀(41)과 튜브(s1)를 통해 강제 흡입하게 되는 것이다.At this time, the tube (s1) connected to the supply / discharge hole 41 is connected to the mechanical device 100, the mechanical device 100, as well as supplying the discharge liquid to the electrode 30, during discharge processing The harmful gas generated is forced to be suctioned through the supply / discharge hole 41 and the tube s1.

상기 척 본체(20)는 상기 프레임(10)에 결합 구성되며, 서로 다른 직경을 가지는 상기 전극(30)들의 교체 장착이 가능하도록 그 내부에는 서로 다른 직경을 가지는 장착부(21)를 다단 구성한다.The chuck body 20 is configured to be coupled to the frame 10, and the mounting portion 21 having different diameters is configured in multiple stages to allow replacement of the electrodes 30 having different diameters.

상기 전극(30)은 상기 척 본체(20)에 장착된 상태에서, 방전액 공급이 이루어질 때 작업테이블(1) 위에 올려진 공작물(W)을 방전가공을 하며, 상기 방전액 공급이 이루어지도록 내부에는 미세구멍(미도시)이 마련된다.In the state where the electrode 30 is mounted on the chuck body 20, when the discharge liquid is supplied, the workpiece 30 is discharge-processed on the work table 1, and the discharge liquid is supplied inside. The fine hole (not shown) is provided in this.

즉, 본 발명은 첨부된 도 1 내지 도 3에서와 같이, 척 본체(20)에 전극(30)을 장착한 상태에서 방전가공기를 작동시키면, 방전가공기의 헤드부(2)에 설치되는 프레임(10)에 고정된 상기 척 본체(20)가 고정되며, 이때 상기 척 본체(20)에 장착된 전극(30)이 공작물(W)과 접촉하여, 상기 공작물(W)을 가공한다.That is, according to the present invention, as shown in FIGS. 1 to 3, when the electric discharge machine is operated in a state in which the electrode 30 is mounted on the chuck body 20, the frame installed on the head part 2 of the electric discharge machine ( The chuck body 20 fixed to 10 is fixed, and at this time, the electrode 30 mounted on the chuck body 20 comes into contact with the workpiece W to process the workpiece W.

이때, 기계장치(100)를 통해 상기 프레임(10)의 측부에 마련되는 공급/배출홀(41)로 방전액을 공급하면, 상기의 방전액은 전극(30)의 단부로 이송되면서, 상기 전극(30)의 방전가공을 원활하게 한다.At this time, when the discharge liquid is supplied to the supply / discharge hole 41 provided on the side of the frame 10 through the mechanical device 100, the discharge liquid is transferred to the end of the electrode 30, the electrode Smooth discharge processing of (30).

여기서, 본 발명에서는 상기 공급/배출홀(41)을 통해 방전액을 공급하는 한편, 유해가스를 강제 배출시키는 것으로 설명이 이루어졌지만, 상기 공급/배출홀(41)을 통해서는 유해가스만 강제 배출시키고, 방전액은 별도의 장치를 통해 공급이 이루어지도록 할 수도 있는 것이다.Here, although the present invention has been described as forcibly discharging harmful gas while supplying a discharge liquid through the supply / discharge hole 41, only harmful gas is forcibly discharged through the supply / discharge hole 41. The discharge liquid may be supplied through a separate device.

한편, 상기와 같이 전극(30)에 의한 방전가공시에는 유해한 가스가 발생하게 되는데, 상기의 유해가스는 전극(30)의 미세구멍을 통해 척 본체(20)의 내부를 따라 공급/배출홀(41)로 안내되면서, 작업공간으로 배출하지 않고, 상기 기계장치(100)의 내부에 형성되는 방전유에 녹으면서 자동 배출되어, 유해가스가 작업자에 미치는 영향을 최소화시키게 된다.On the other hand, as described above, during the discharge processing by the electrode 30, harmful gas is generated, the harmful gas is supplied / discharge hole along the inside of the chuck body 20 through the micro-holes of the electrode 30 ( While being guided to 41, it is automatically discharged while melting in the discharge oil formed in the interior of the machine 100, without discharging to the work space, thereby minimizing the impact of harmful gases on the worker.

즉, 상기 공급/배출홀(41)에는 튜브(s1)를 통해 기계장치(100)가 연결되는 바, 상기 기계장치(100)는 방전가공을 위한 제어부(미도시)의 제어를 받아 상기 전극(30)의 방전가공의 동작이 이루어질 때 동작하면서 흡입력을 발생시킨다.That is, the mechanical device 100 is connected to the supply / discharge hole 41 through a tube s1, and the mechanical device 100 is controlled by a controller (not shown) for electric discharge machining. The suction force is generated while the electric discharge machining of 30) is performed.

그러면, 상기의 흡입력으로부터 전극(30)의 방전가공시 발생하는 유해가스는 상기 전극(30)의 미세구멍과 상기 척 본체(20)의 내부 공간을 따라 공급/배출홀(41)로 안내되고, 이와동시에 상기 공급/배출홀(41)에 연결되는 튜브(s1)를 통해 상기 기계장치(100)의 내부 방전유 보관 탱크로 보내지면서 집진되는 것이다.Then, the harmful gas generated during the discharge machining of the electrode 30 from the suction force is guided to the supply / discharge hole 41 along the micropores of the electrode 30 and the inner space of the chuck body 20. At the same time it is collected while being sent to the internal discharge oil storage tank of the mechanical device 100 through the tube (s1) connected to the supply / discharge hole (41).

이에따라, 작업장 내부에는 유해한 가스가 존재하지 않게 되어 항시 청정한 상태의 실내공기를 유지하게 되면서 작업환경의 개선 향상 및 작업자의 건강을 유지시켜 줄 수 있게 되는 것이다.Accordingly, there is no harmful gas inside the workplace to maintain the indoor air in a clean state at all times to improve the working environment and maintain the health of the worker.
