To the head 10 'of the high information bolt 10, the vertically penetrates the air hole 12 through which air flows into the inner and outer sides of the rotating shaft 2 and is serrated in the rotary cutter 9; A plurality of air discharge grooves 13 are formed in the cutting part 70 and the guide ring 11 is installed so that the rotary cutter 9 and the air passage 14 are formed. The air introduced through the air hole 12 is reflected and discharged into the air discharge groove 13 of the rotary cutter 9 through the hole 15 and the air passage 14 of the high information bolt 10, and the guide flange ( 6) has a structure in which a magnetic force is released through a magnetic discharge hole 20 drilled in the guide flange 6 by embedding a magnet 16 covering the magnetic cap 19 for magnetic force blocking.

도면중 미설명 부호 17은 피가공물이고, 18은 구동축(1)과 회전축(2)을 치합한 베벨기어 이다.In the figure, reference numeral 17 denotes a workpiece, and 18 denotes a bevel gear in which the drive shaft 1 and the rotation shaft 2 are engaged with each other.

이와같이 된 본 발명은 면취기 본체에 베어링으로 회전되게 결합된 회전나사링과 회전캡의 안내플랜지를 피가공물의 상면에 당접시키면서 안내플랜지(6)의 중심 구멍으로 돌출된 로타리 컷터(9)의 호면(a)에 형성된 톱니형 절삭부(70)를 도 1과 같이 피가공물(17)의 모서리에 면접시켜 에어의 구동력으로 회전되는 회전축(2)에 의해 로타리 컷터(9)를 회전시키면서 피가공물(17)의 모서리를 면취가공을 하게 하면 피가공물(17)의 모서리가 로타리 컷터(9)의 톱니형 절삭부(70)에 형성된 호면 (a)과 동일한 라운드로 일정하게 간단하게 면취되고 이어서 로타리 컷터(9)를 피가공물(17)의 모서리에 긴밀히 면접시킨 상태로 옆으로 이동시키게 되면 피가공물 (17)의 수평면은 안내플랜지(6)가, 그리고 수직면은 로타리 컷터(9)의 하부에 베어링(5)으로 설치된 가이드 링(11)이 각각 면접되어 안내플랜지(6)는 베어링(5)으로 회전되는 회전캡(7)의 회전으로 또 가이드 링(11)은 베어링(5)의 회전으로 원활하게 회전되면서 옆으로 이동이 이루어지므로 피가공물(17)의 모서리를 일정하고 균일하게 면취함은 선출원의 작용과 동일하다.According to the present invention, the rotary screw ring rotatably coupled to the chamfering body and the guide flange of the rotary cap abut the upper surface of the workpiece while the arc surface of the rotary cutter 9 protrudes into the center hole of the guide flange 6. As shown in FIG. 1, the toothed cutting part 70 formed at (a) is interviewed at the edge of the workpiece 17 to rotate the rotary cutter 9 by the rotary shaft 2 rotated by the driving force of air. When the edge of the workpiece 17 is chamfered, the edge of the workpiece 17 is simply chamfered uniformly in the same round as the arc surface (a) formed in the toothed cutting portion 70 of the rotary cutter 9, and then the rotary cutter (9) is moved to the side in close contact with the edge of the workpiece (17), the horizontal surface of the workpiece (17) is the guide flange (6), and the vertical plane is a bearing ( 5) Installed guide ring (11) Each of the guide flanges 6 are interviewed and the guide ring 11 is smoothly rotated by the rotation of the bearing 5 and the guide ring 11 is rotated by the rotation of the bearing 5. Constant and uniform chamfering of the edges of the workpiece 17 is the same as the action of the prior application.

여기서 본 발명은 안내플랜지(6)의 내부 일단에 자석(16)을 부착하였으므로 면취시 안내플랜지(6)를 피가공물(17)의 상면에 면접시키게 되면 안내플랜지(6)는 자석(16)의 자력으로 피가공물(17)에 긴밀하게 밀착이 이루어져 면취시 안내플랜지 (6)가 피가공물(17)의 상면으로 부터 떨어지지 않게 됨에 따라 작업자가 안내플랜지(6)를 피가공물(17)에 면접시키기 위해 억지로 힘을 가하지 않아도 되므로 면취작업을 보다 용이하게 할 수 있는 바, 일반적으로 자석(16)은 분리시키기는 어려워도 부착된 상태에서 슬라이드 시키기는 용이하므로 안내플랜지(6)가 피가공물(17)에 부착된 상태에서 옆으로 이동시켜 가면서 실시하는 면취작업은 용이하게 이루어질 수 있게 되며, 자석(16)의 외부에는 자력차단용 동캡(19)이 덮어 씌워져 저부를 제외한 외부로는 자력이 차단되는 반면에 저면에 뚫은 자력방출공(20)으로만 자력이 방출되어 피가공물(17)과의 접착이 보다 강하게 이루어지게 된다.In the present invention, since the magnet 16 is attached to the inner end of the guide flange 6, when the guide flange 6 is interviewed on the upper surface of the workpiece 17 when chamfering, the guide flange 6 is connected to the magnet 16. Close contact with the workpiece 17 by magnetic force causes the guide flange 6 not to fall off from the upper surface of the workpiece 17 when chamfered, so that the operator interviews the guide flange 6 to the workpiece 17. The chamfering operation can be made easier because no force is applied to the bar. In general, the magnet 16 is difficult to separate, but the guide flange 6 is easy to slide in the attached state. The chamfering work carried out while moving to the side in the attached state can be made easily, and the magnetic shielding copper cap 19 is covered on the outside of the magnet 16 to block the magnetic force to the outside except the bottom. On the other hand, only the magnetic force release hole 20 is drilled into the bottom surface of the magnetic force is released will be written stronger than the adhesion of the workpiece (17).

그리고 회전축(2)에는 에어공(12)이 수직으로 관통되고 로타리 컷터(9)의 톱니형 절삭부(70)에 다수개의 에어 배출홈(13)이 형성되며, 로타리 컷터(9)의 하부에 유설된 가이드 링(11)과의 사이에 에어통로(14)가 형성되어 있으므로 회전축(2)이 에어로서 작동되는 구동축(1)에 의해 회전되면 이때 공급된 에어의 일부가 회전축(2)에 관통된 에어공(12)으로 유입되어 고정보울트(10)의 구멍(15)을 통해 에어통로(14)로 유입되는 데 이때 에어통로(14)로 유입된 압축에어는 가이드 링(11)에 부딪쳐 위로 반사됨과 동시에 상부에 위치한 로타리 컷터(9)의 톱니형 절삭부(70)의 에어 배출홈(13)으로 분사되면서 빠져 나가게 되므로 로타리 컷터(9)가 압축에어에 의해 공냉이 이루어지게 되고 이와 함께 면접된 피가공물(17)도 냉각시키게 됨에 따라 면취기와 피가공물(17)의 과열을 방지하게 되며 뿐만 아니라 로타리 컷터(9)에 의해 절삭된 절삭칩이 분사되는 압축에어에 의해 불어져 제거되므로 절삭면이 잘 보이게 되고 칩에 의해 절삭작업이 방해받는 폐단이 발생하지 않게 된다.In addition, the air shaft 12 penetrates vertically through the rotation shaft 2, and a plurality of air discharge grooves 13 are formed in the sawtooth cut portion 70 of the rotary cutter 9, and the lower portion of the rotary cutter 9 Since the air passage 14 is formed between the guide ring 11, which is installed, when the rotating shaft 2 is rotated by the driving shaft 1 operated as air, a part of the supplied air penetrates the rotating shaft 2 at this time. Flows into the air hole 12 and flows into the air passage 14 through the hole 15 of the high information bolt 10. At this time, the compressed air introduced into the air passage 14 hits the guide ring 11 and moves upward. At the same time it is reflected and exited by being injected into the air discharge groove 13 of the toothed cutting portion 70 of the rotary cutter 9 located on the upper side, the rotary cutter 9 is air-cooled by compressed air and interviewed with it. As the processed workpiece 17 is also cooled, overheating of the chamfer and the workpiece 17 is prevented. In addition, since the cutting chips cut by the rotary cutter 9 are blown out by the compressed air which is injected, the cutting surface is well visible, and the closed end is prevented from being interrupted by the chips.

여기서 로타리 컷터(9)에 형성된 에어 배출홈(13)은 톱니형 절삭부(70)의 요입홈을 따라 일정간격으로 형성하게 되고 회전축(2)에 뚫린 에어공(12)과 고정보울트(10)에 뚫은 구멍(15)은 한개 이상을 면취기의 크기에 따라 조절하여 관통시키면 되는 것이다.Here, the air discharge groove 13 formed in the rotary cutter 9 is formed at regular intervals along the recessed groove of the saw-tooth cutting part 70, and the air hole 12 and the high information bolt 10 drilled in the rotary shaft 2 are formed. Hole 15 drilled in the one or more to be adjusted to penetrate according to the size of the chamfering machine.

이와같이 본 발명은 면취장치의 로타리 컷터(9)를 자석(16)에 의해 피가공물 (17)에 긴밀하게 접착시킬 수 있어 면취작업을 용이하게 할 수 있고, 면취기와 피가공물을 압축에어로서 공냉시켜 작업자의 화상을 방지함과 동시에 기계의 수명을 연장시키며 절삭칩을 불어내 면취작업을 보다 용이하게 할 수 있는 등 그 효과가 매우 크다.As described above, the present invention can closely adhere the rotary cutter 9 of the chamfering apparatus to the workpiece 17 by the magnet 16, thereby facilitating the chamfering operation, and by cooling the chamfering and the workpiece as compressed air. It is very effective in preventing the burn of the operator and extending the life of the machine and making the chamfering work easier by blowing the cutting chips.
