도 1 내지 도 3에는 종래에 일반적으로 사용되어온 각도 절단기가 도시되어 있다.1 to 3 illustrate an angle cutter that has been commonly used in the prior art.

각도 절단기는 도 1과 같이 베이스(1)에 축(2)으로 회전가능하게 결합된 프레임(3)과, 상기 프레임에 설치된 톱날(5)과, 상기 프레임에 일체형으로 형성된 손잡이(4) 및 스위치(6)와, 상기 베이스에 설치된 각도 조절 손잡이(7)와, 상기 베이스위에 설치되어 피가공물을 고정하는 고정장치로 구성되어 있다.As shown in FIG. 1, the angle cutter includes a frame 3 rotatably coupled to a shaft 2 to the base 1, a saw blade 5 installed on the frame, a handle 4 integrally formed on the frame, and a switch. (6), an angle adjusting knob (7) provided on the base, and a fixing device provided on the base to fix the workpiece.

또한 상기 고정장치는 도 2와 같이 베이스에 수직상으로 설치된 샤프트(8)와, 상기 샤프트에 회동가능하게 결합된 회동편(9)과, 상기 회동편을 원하는 회전각도에서 고정하기 위한 나비너트(10)와, 상기 회동편에 수직상으로 나사결합된 나사축(11)과, 상기 나사축의 상단에 고정된 원통손잡이(12)와, 상기 나사축의 하단에 고정된 지지판(13)으로 이루어져 있다.In addition, the fixing device is a shaft (8) installed perpendicular to the base as shown in Figure 2, a rotating piece (9) rotatably coupled to the shaft, and a butterfly nut for fixing the rotating piece at a desired rotational angle ( 10), a screw shaft 11 screwed vertically to the pivoting piece, a cylindrical handle 12 fixed to the upper end of the screw shaft, and a support plate 13 fixed to the lower end of the screw shaft.

따라서, 절단작업시 베이스(1)위에 피가공물(14)을 올려 놓고 회동편(9)을 움직여 지지판(13)이 피가공물의 상부에 위치되게 한 후 나비서트(10)를 조이고, 원통손잡이(12)를 돌려 나사축(11)을 하강시키면 나사축(11)하단에 고정된 지지판(13)이 피가공물에 밀착되면서 피가공물은 베이스 위에 고정된다.Therefore, in the cutting operation, the workpiece 14 is placed on the base 1 and the pivoting piece 9 is moved so that the support plate 13 is positioned on the upper part of the workpiece. Then, the butterfly 10 is tightened and the cylindrical handle ( 12) When the screw shaft 11 is lowered by turning, the support plate 13 fixed to the lower end of the screw shaft 11 is in close contact with the workpiece, and the workpiece is fixed on the base.

또한 상기와 같이 피가공물이 고정된 상태에서 손잡이(4)를 잡고 스위치(6)를 온 시킨 후 하방으로 누르면 프레임(3)이 축(2)을 중심으로 회동을 하면서 톱날(5)이 함께 움직여 피가공물이 톱날(5)에 의해 절단된다.In addition, while holding the handle (4) in the state in which the workpiece is fixed as described above and pressing the switch 6 downwards, the saw blade (5) moves together while the frame (3) is rotated about the axis (2) The workpiece is cut by the saw blade 5.

한편 절단작업이 끝나면 원통손잡이(12)를 돌려 지지판(13)을 상승시키고 나비너트(10)를 풀어 회동편(9)을 회전시킴에 의해 지지판(13)이 피가공물의 상부에서 벗어나게 한 후 가공된 제품을 빼내고 다시 새로운 피가공물을 고정하여 절단작업을 하게 된다.On the other hand, after the cutting operation is completed, turn the cylindrical handle 12 to raise the support plate 13, loosen the butterfly nut 10, and rotate the pivoting piece 9 so that the support plate 13 is released from the upper part of the workpiece. The product is removed and the new work piece is fixed and cut.

그러나 상기와 같은 종래의 각도 절단기는 피가공물을 고정할때마다 나비너트(10)를 풀어 회동편(9)을 회전시킨 후 다시 조이고 원통손잡이(12)를 돌려 지지판(13)을 피가공물에 밀착시켜야 하는 조작상의 번거로움이 있으며, 가공된 제품을 빼낼 때에도 상기와 같은 조작을 역순으로 반복해야 하므로 작업성이 저하되는 문제가 있다.However, in the conventional angle cutter as described above, each time the workpiece is fixed, the butterfly nut 10 is released to rotate the rotating piece 9, and then is tightened again. The cylindrical knob 12 is rotated to closely adhere the support plate 13 to the workpiece. There is an operation troublesome to be done, there is a problem that the workability is deteriorated because the above operation must be repeated in the reverse order even when removing the processed product.

상기 베이스(1)의 전방에는 고정구 몸체(21)가 축(22)으로 회전가능하게 설치되어 있고 상기 고정구 몸체(21)의 선단부에는 지지판(23)이 구(球) 형상의 볼(Ball)부 (23a)에 의해 회전자유롭게 설치되어 있으며, 상기 지지판의 후방에는 지지판에 탄력성을 부여하기 위한 스프링(24)이 설치되어 있다.In the front of the base 1, the fixture body 21 is rotatably installed on the shaft 22, and the support plate 23 is a ball-shaped ball portion at the tip of the fixture body 21. Rotation is provided freely by 23a, and the back 24 of the said support plate is provided with the spring 24 for giving elasticity to a support plate.

상기 고정구 몸체(21)와 손잡이(4) 사이에는 고정구 몸체(21)를 손잡이(4)의 작동과 연동시키기 위한 와이어(25)가 연결되어 있으며, 상기 와이어(25)는 도르레 역할을 하는 제 1 활차(2b)과 제 2 활차(27) 및 제 3 활차(28)를 경유하여 손잡이와 고정구 몸체 사이에 연결되어 있다.A wire 25 is connected between the fixture body 21 and the handle 4 to interlock the fixture body 21 with the operation of the handle 4, and the wire 25 serves as a pulley. It is connected between the handle and the fixture body via the pulley 2b, the second pulley 27 and the third pulley 28.

상기 각 활차중 프레임(3)에 설치된 제 1 활차(26)는 프레임의 회전중심축(2)보다 일정거리(L)만큼 높게 위치되어 손잡이(4)를 누를 때 와이어(25)가 당겨지도록 되어 있으며, 제 3 활차(28)는 고정구 몸체(21)에 고정된 와이어(25)의 끝단부보다 낮게 위치되어 와이어(25)가 당겨질 때 고정구 몸체(21)가 축(22)을 중심으로 하여 피가공물(14) 방향으로 회전하도록 되어 있다.The first pulley 26 installed on each of the pulleys 3 is positioned higher by a distance L than the center of rotation shaft 2 of the frame so that the wire 25 is pulled when the handle 4 is pressed. The third pulley 28 is positioned lower than the end of the wire 25 fixed to the fixture body 21 such that the fixture body 21 is centered about the shaft 22 when the wire 25 is pulled. It is made to rotate to the workpiece | work 14 direction.

각 활차중 제 2 활차(27)는 제 1 활차와 제 3 활차 사이에 위치하여 와이어(25)의 안내역할을 한다.The second pulley 27 of each pulley is positioned between the first pulley and the third pulley to serve as a guide of the wire 25.

상기와 같이된 본 발명의 각도 절단기는 피가공물(14)을 베이스(1)위에 올려 놓고 절단하기 위해 손잡이(4)를 누르면 프레임(3)과 일체로 형성된 손잡이(4)가 축(2)을 중심으로 회전함과 동시에 와이어(25)가 당겨지고 와이어(25)가 당겨짐에 따라 고정구 몸체(21)는 축(22)을 중심으로 도 2의 반시계 방향으로 회전을 하게 된다.In the angle cutter of the present invention as described above, the handle (4) formed integrally with the frame (3) by pressing the handle (4) to put the workpiece 14 on the base (1) and cut the shaft (2) As the wire 25 is pulled and the wire 25 is pulled at the same time, the fixture body 21 rotates about the shaft 22 in the counterclockwise direction of FIG. 2.

이때, 고정구 몸체(21)의 선단부에 설치된 지지판(23)이 도 5과 같이 피가공물(14)의 표면에 밀착하면서 피가공물을 고정하게 되는데, 전술한 바와 같이 상기 지지판(23)은 둥근 형상의 볼부(23a)에 의해 고정구 몸체(21)와 연결되어 있기 때문에 자유롭게 회전운동을 하면서 피가공물의 표면에 긴밀하게 밀착되고 지지판의 후방에 설치된 스프링(24)은 지지판(23)에 스프링력을 가해 피가공물을 보다 견고히 고정할 수 있게 하여 준다.At this time, the support plate 23 installed at the distal end of the fixture body 21 is fixed to the workpiece while being in close contact with the surface of the workpiece 14 as shown in Figure 5, the support plate 23 has a round shape Since it is connected to the fixture body 21 by the ball portion 23a, the spring 24, which is closely attached to the surface of the workpiece while being freely rotated and installed behind the support plate, applies a spring force to the support plate 23 to avoid This makes it possible to fix the workpiece more firmly.

또한 상기와 같이 손잡이(4)의 회전에 따라 피가공물이 고정된 상태에서 손잡이(4)를 더욱 누르면 톱날(5)에 의해 피가공물이 절단된다.In addition, the workpiece is cut by the saw blade 5 when the handle 4 is further pressed in the state where the workpiece is fixed as the handle 4 rotates as described above.

그리고 피가공물의 절단 작업이 완료된 후 손잡이(4)의 누르는 힘을 제거하면 손잡이가 원위치로 복귀하면서 와이어(24)를 당기는 힘이 소멸되어 와이어(24)도 원위치로 이동하고 와이어의 이동에 따라 고정구 몸체(21)도 원위치로 회전하여 피가공물의 고정을 해제하게 된다.After the cutting work is completed, the pressing force of the handle 4 is removed, and the force of pulling the wire 24 disappears as the handle returns to the original position, so that the wire 24 moves to the original position and the fixture is moved according to the movement of the wire. The body 21 also rotates to its original position to release the workpiece.

상기에서와 같이 본 발명은 피가공물의 절단작업을 위해 손잡이를 누르면 손잡이와 연동하는 고정구 몸체에 의해 피가공물이 자동적으로 고정되도록 되어 있으므로 절단작업시마다 매번 나비너트를 풀거나 조이고 원통손잡이를 회전시켜 주어야 하는 조작의 번거로움이 해소되고, 이에 따라 피가공물의 고정 및 해제 작업에 소요되는 시간을 줄어 생산성을 향상시킬 수 있게 된다.As described above, the present invention is to press the handle for cutting the workpiece, the workpiece is to be automatically fixed by the fixture body interlocking with the handle, so each time the cutting operation to loosen or tighten the butterfly nut and to rotate the cylindrical handle The troublesome operation is eliminated, thereby reducing the time required for fixing and releasing the workpiece, thereby improving productivity.
