Description

앤드밀의 팁 체결장치{CONCLUSION EQUIPMENT CHIP INSERT BALL ENDMILL}End mill tip fasteners {CONCLUSION EQUIPMENT CHIP INSERT BALL ENDMILL}

본 고안은 인서트 볼 앤드밀(INSERT BALL ENDMILL)에 체결하여 사용하는 팁(CHIP)과 그 체결장치에 관한 것으로, 팁 자체를 ″S ″형 곡선이 되게하여 절삭저항을 최소로 할수 있도록 하는데 그 목적이 있는 것이다.The present invention relates to a tip (CHIP) used in fastening to an insert ball end mill (INSERT BALL ENDMILL) and its fastening device, and to make the tip itself a ″ S ″ curve to minimize the cutting force. It is.

종래에 사용되어온 앤드밀은 팁과 앤드밀을 체결할때 앤드밀의 체결부에 앤드밀의 길이와 같은 방향으로 돌출부가 형성되고 팁에는 길이방향으로 체결홈이 형성되어 있기 때문에 앤드밀이 작동될 경우 팁이 절삭저항에 의하여 유동되어 정확한 작업을 할수가 없는 단점이 있었다.In the conventional end mill, when the tip and the end mill are engaged, a protrusion is formed at the end of the end mill in the same direction as the length of the end mill, and a fastening groove is formed at the tip in the longitudinal direction, so that the tip has a cutting force when the end mill is operated. There was a drawback that can not be precisely moved by the flow.

즉 앤드밀은 그 성격상 절삭 부하변동이 심한 단점이 있으며, 이로 인하여 종래에 사용되어 온 앤드밀과 팁은 그 체결방식이 앤드밀의 길이 방향으로 되어 있음으로 흔들림이 발생되는 단점이 있었으며, 또한 팁 자체가 수평으로 구성되어 있기 때문에 작업중 절삭저항이 심한 문제점이 있었다.In other words, the end mill has a disadvantage in that the cutting load fluctuates severely. Therefore, the end mill and the tip used in the related art have a disadvantage in that shaking occurs because the fastening method is in the longitudinal direction of the end mill. Due to the horizontal configuration, cutting resistance was severe during the operation.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서, 앤드밀의 팁 체결부에 앤드밀의 폭방향으로 체결돌기를 형성하고 팁의 저면에는 앤드밀의 체결돌기와 같은 방향으로 체결홈을 형성하며, 팁 자체를 만곡지게 형성하여 절삭저항을 최소로 할수 있도록한 것으로서, 이하 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been made in order to solve the above problems, forming a fastening protrusion in the width direction of the end mill in the tip fastening portion of the end mill and a fastening groove in the same direction as the fastening protrusion of the end mill on the bottom of the tip, the tip itself As to be formed to be curved to minimize the cutting resistance, the present invention will be described in detail by the accompanying drawings as follows.

팁이 체결되는 앤드밀에 있어서, 앤드밀(1)의 체결부에 앤드밀의 폭방향(45°)으로 2줄의 체결돌기(2)를 형성하고, 만곡지게 형성된 팁(3)의 저면에는 폭방향으로 체결홈(4)을 형성하여 체결돌기(2)가 체결되게 하여서 된 것으로서 미 설명 부호 5는 고정공, 6은 팁을 고정하는 고정나사를 보인 것이다.In the end mill to which the tip is fastened, two fastening protrusions 2 are formed in the fastening portion of the end mill 1 in the width direction (45 °) of the end mill, and the width of the bottom surface of the tip 3 is formed to be curved in the width direction. As the fastening groove 2 is formed by forming the fastening groove 4, the reference numeral 5 is a fixing hole, and 6 shows a fixing screw for fixing the tip.

상기와 같이 된 본 고안의 사용방법을 설명하면 다음가 같다.Referring to the use of the present invention made as described above is as follows.

앤드밀(1)의 체결돌기(2)에 팁(3)의 저면에 형성되어 있는 체결홈을 댄 다음 팁의 중앙부에 형성되어 있는 고정공에 고정나사를 체결하면 팁 자체가 앤드밀의 체결돌기(2)에 밀착되면서 견고하게 고정됨으로서, 앤드밀이 사용도중 팁(3)이 떨리거나 흔들리는 것을 방지할수가 있는 것이다.Put the fastening groove formed on the bottom surface of the tip 3 to the fastening protrusion 2 of the end mill 1, and then fasten the fixing screw to the fixing hole formed in the center of the tip. By being firmly fixed in close contact with the end), the end mill can prevent the tip 3 from shaking or shaking during use.

한편 앤드밀(1)에 팁(3)을 체결할 경우 전후면에 체결되는 팁(3) 자체가 ' S ' 모양으로 형성되기 때문에 절삭저항을 최소로 줄일수가 있으며, 또한 팁의 전체 형성이 거의 만곡지게 형성되어 있기 때문에 흔들림과 저항을 최소로 할수강ㅆ는 것이다.On the other hand, when the tip 3 is fastened to the end mill 1, since the tip 3 itself fastened to the front and rear surfaces is formed in an 'S' shape, cutting resistance can be reduced to a minimum, and the overall formation of the tip is almost curved. Because it is formed plentifully, the shaking and resistance can be minimized.

이상과 같이 본 고안은 앤드밀의 팁 체결부에 앤드밀의 폭방향으로 체결돌기를 형성하고 팁의 저면에는 앤드밀의 체결돌기와 같은 방향으로 체결홈을 형성하며, 팁 자체를 만곡지게 형성하여 절삭저항을 최소로 할수 있도록한 것으로서, 구조가 간단하여 제작이 용이하고, 앤드밀에 팁이 3점의 접촉면으로 안정되게 고정되기 때문에 흔들림이나 떨림을 방지할수가 있으며 팁자체가 만곡지게 형성됨으로서 절삭저항을 최소로 줄일수가 있는 유용한 고안인 것이다.As described above, the present invention forms a fastening protrusion in the end mill in the width direction of the end mill, and a fastening groove is formed on the bottom of the tip in the same direction as the fastening protrusion of the end mill. The structure is simple and easy to manufacture. Since the tip is fixed to the end mill with 3 points of contact stably, it can prevent shaking or shaking. The tip itself is curved to reduce cutting resistance. It is a useful design that can.
