Description

절삭 공구{CUTTING TOOL}Cutting tool {CUTTING TOOL}

본 발명은 본 출원인의 대한민국 특허출원 제10-2011-0105016호의 "절삭 공구"를 개선한 것이다.
The present invention is an improvement of the "cutting tool" of the applicant's Korean Patent Application No. 10-2011-0105016.

본 출원인의 대한민국 특허출원 제10-2011-0105016호(2011년 10월 14일, 출원)에 "절삭 공구"가 소개되어 있다.A "cutting tool" is introduced in the applicant's Korean Patent Application No. 10-2011-0105016 (filed October 14, 2011).

상기 절삭 공구는 본체의 선단에 절삭날이 형성되고, 본체의 후단에 연결부가 형성되고, 연결부에 절개부가 형성되고, 절개부의 측부로 인서트 수단가 끼워지면, 인서트 부재가 축방향으로 빠지지 않고 걸리는 구조를 갖도록 절개부가 형성되며, 본체의 절개부에 텐셔닝 로드의 인서트부가 끼워져 축방향으로 걸리게 되고, 본체의 연결부가 자루 홀더의 결합구멍에 끼워지면, 결합구멍에 배치된 키이가 절개부의 측단에 각각 걸려, 본체에 대한 자루 홀더의 상대 회전이 방지되고, 자루 홀더에 형성된 결합구멍과 중공부가 중간 격막에 의해 차단되고, 격막에 관통구멍이 형성되어, 절개부에 인서트부가 결합된 텐셔닝 로드가 자루 홀더의 관통구멍을 통해 자루 홀더의 중공부로 돌출되고, 자루 홀더의 중공부로 인입되는 너트부재가 텐셔닝 로드의 볼트 나선부에 체결된다.The cutting tool has a structure in which a cutting edge is formed at the front end of the main body, a connecting part is formed at the rear end of the main body, a cutting part is formed at the connecting part, and an insert member is caught without being pulled out in the axial direction when the insert means is inserted into the side of the cutting part. An incision is formed so that the insert part of the tensioning rod is hung in the axial direction, and when the connecting part of the main body is fitted into the coupling hole of the bag holder, the key disposed in the coupling hole is hooked to the side end of the incision. The rotation of the bag holder relative to the main body is prevented, the coupling hole and the hollow part formed in the bag holder are blocked by the intermediate diaphragm, the through hole is formed in the diaphragm, and the tension rod having the insert portion coupled to the cutout is a bag holder. The nut member protrudes through the through hole of the bag holder into the hollow part of the bag holder and is introduced into the bag holder hollow part. It is fastened to the helix.

그러나, 상기 절삭 공구는 자루 홀더에 장착된 본체를 교체하기 위해 텐셔닝 로드에 체결된 너트부재를 풀러도, 본체의 연결부와 자루 홀더의 결합구멍에 압착되어 있어, 본체의 연결부가 자루 홀더의 결합구멍에서 잘 분리되지 않으며, 본체의 연결부를 자루 홀더의 결합구멍에서 분리하기 위해 별도의 도구가 요구된다.
However, the cutting tool is squeezed into the coupling part of the main body and the bag holder, even if the nut member fastened to the tensioning rod is removed to replace the main body mounted on the bag holder. It does not separate well from the hole, and a separate tool is required to separate the connection of the body from the coupling hole of the bag holder.

따라서, 본 발명의 목적은 자루 홀더의 중공부 후단에 무드볼트를 체결함으로써, 무드볼트를 이용하여 자루 홀더의 결합홈에 압착된 본체의 연결부를 쉽게 분리할 수 있고, 분리 과정에서 본체의 연결부가 파손되는 것을 방지할 수 있는 절삭 공구를 제공하는 것이다.
Accordingly, an object of the present invention is to fasten the mood bolt to the rear end of the hollow portion of the bag holder, it is possible to easily separate the connection of the main body pressed to the coupling groove of the bag holder using the mood bolt, the connection portion of the body in the separation process It is to provide a cutting tool that can prevent breakage.

상기와 같은 목적을 달성하기 위한 본 발명은 절삭날이 형성된 본체의 후단에 연결부가 테이퍼지게 형성되고, 연결부에 절개부가 형성되고, 절개부에 텐셔닝 로드의 인서트부가 끼워져 축방향으로 걸리게 되고, 본체의 연결부가 자루 홀더의 결합홈에 끼워지면, 결합홈에 배치된 키이가 절개부의 측단에 각각 걸려, 본체에 대한 자루 홀더의 상대 회전이 방지되고, 자루 홀더에 형성된 결합홈과 중공부가 중간 격막에 의해 차단되고, 중간 격막에 관통구멍이 형성되어, 절개부에 인서트부가 결합된 텐셔닝 로드의 나선체결부가 자루 홀더의 관통구멍을 통해 자루 홀더의 중공부로 돌출되고, 텐셔닝 로드의 나선체결부가 자루 홀더의 중공부로 인입되는 조임부재의 너트부에 체결되는 절삭 공구에 있어서, 상기 조임부재의 후단(너트부의 반대편)에 제 1 렌치홈이 형성되고, 자루 홀더의 중공부에 나선체결부가 형성되고, 나선체결부에 무드볼트가 체결되고, 무드볼트에 렌치구멍과 제 2 렌치홈이 형성되는 것을 특징으로 한다.
In order to achieve the above object, the present invention provides a tapered connection portion at the rear end of the main body on which the cutting edge is formed, an incision portion is formed in the connection portion, and an insert portion of the tensioning rod is inserted into the incision portion and hung in the axial direction. When the connecting portion of the bag is fitted into the coupling groove of the bag holder, the keys arranged in the coupling groove are caught on the side ends of the incision, respectively, to prevent relative rotation of the bag holder with respect to the main body, and the coupling groove and the hollow portion formed in the bag holder are placed in the middle diaphragm. Through-holes are formed in the middle diaphragm, the helical fastening portion of the tensioning rod having the insert portion coupled to the incision portion projects through the through-hole of the sack holder into the hollow portion of the sack holder, and the helical fastening portion of the tensioning rod A cutting tool fastened to a nut part of a tightening member introduced into a hollow part of a holder, the first tool of which is connected to a rear end of the tightening member (opposite to a nut part). Chihom is formed, the additional tightening spiral to the hollow portion of the bag holder is formed, and the mood bolt being fastened to the connection part helical, it characterized in that the hole in the wrench and a second wrench groove formed on mood bolt.

이것에 의해, 본 발명에 따른 절삭 공구는 텐셔닝 로드에 체결되어 조여진 조임부재을 느슨하게 푼 다음, 무드볼트를 조이면, 무드볼트가 조임부재를 가압하게 되고, 조임부재가 텐셔닝 로드를 밀게 되어, 텐셔닝 로드가 본체의 연결부를 밀게 됨으로써, 자루 홀더의 결합홈에 압착된 본체의 연결부가 자루 홀더의 결합홈에서 쉽게 분리되고, 별도의 도구를 요구하지 않는 효과가 있다.
As a result, the cutting tool according to the present invention loosens the tightening member fastened to the tensioning rod, and then tightens the mood bolt, which causes the mood bolt to pressurize the tightening member, and the tightening member pushes the tensioning rod. By pushing the coupling rod of the body, the connecting portion of the main body pressed into the coupling groove of the bag holder is easily separated from the coupling groove of the bag holder, there is an effect that does not require a separate tool.
