Description

절삭공구 체결홀더{The Holder for Cutting Tool}Cutting tool fastening holder {The Holder for Cutting Tool}

본 발명은 공작기계에 장착되어 금속가공물을 선삭하거나 절단할 때 사용되는 절삭공구를 장착하는 체결홀더에 관한 것으로, 특히 블럭몸체를 분할 조립형태로 구성하여 블럭 마모시 해당 부위만 신속하게 교체할 수 있도록 하고 체결볼트를 이용한 테이퍼팁을 구비하여 절삭공구를 용이하게 탈·장착할 수 있도록 하는 절삭공구 체결홀더에 관한 것이다. The present invention relates to a fastening holder for mounting a cutting tool used for turning or cutting a metal workpiece in a machine tool, and in particular, the block body is configured in a divided assembly form so that only the corresponding parts can be quickly replaced when the block wears. The present invention relates to a cutting tool fastening holder having a tapered tip using a fastening bolt to easily remove and mount the cutting tool.

일반적으로 공작기계를 이용하여 선삭가공이나 절단가공 등을 수행하는 경우, 금속가공물을 가공하는 공구 즉 바이트 등을 체결하는 체결홀더를 공작기계에 장착하여 가공작업을 수행하게 된다. 이와 같이 금속가공물을 가공하는 절삭공구를 체결하여 공작기계 등에 장착하는 종래의 절삭공구 체결홀더(30)는 도5와 도6에 도시되어 있는 바와 같이, 공작기계의 클램프(도시안됨)에 장착되는 블럭몸체장착부(31)와 절삭공구(32)가 끼워 설치되는 블레이드장착부(33)가 하나의 단일 몸체로 구성되어 상기 블레이드장착부(33)에 절삭공구(32)를 끼워 체결볼트(34)로 체결하는 구조로 이루어지되 상기 블레이드장착부(33)에는 상기 블레이드장착부(33)와 수직하게 일정 길이만큼 절개홈부(35)가 형성된 구조로 되어있다.In general, in the case of performing turning or cutting by using a machine tool, a tool for processing a metal workpiece, that is, a fastening holder for fastening a bite, etc. is mounted on the machine tool to perform a machining operation. Thus, the conventional cutting tool fastening holder 30 for fastening a cutting tool for processing a metal workpiece and mounting it on a machine tool is mounted on a clamp (not shown) of the machine tool, as shown in FIGS. 5 and 6. The block mounting portion 31 into which the block body mounting portion 31 and the cutting tool 32 are installed is configured as a single body, and the cutting tool 32 is inserted into the blade mounting portion 33 to be fastened by a fastening bolt 34. The blade mounting portion 33 has a structure in which the cutting groove 35 is formed by a predetermined length perpendicular to the blade mounting portion 33.

그리고 상기 절삭공구(32)는 몸체를 형성하는 블레이드(321)와 절삭날을 이루는 인서트(322,insert)로 구성된다.The cutting tool 32 is composed of a blade 321 forming a body and an insert 322 forming a cutting edge.

상기와 같이 구성된 종래의 절삭공구 체결홀더(30)는 상기 블럭몸체장착부(31)와 일체로 형성된 상기 블레이드장착부(33)에 상기 블레이드(321)를 삽설한 후 상기 체결볼트(34)로 체결하면 상기 블레이드(321)가 견고하게 체결 고정된다.In the conventional cutting tool fastening holder 30 configured as described above, when the blade 321 is inserted into the blade mounting portion 33 formed integrally with the block body mounting portion 31 and then fastened with the fastening bolt 34. The blade 321 is firmly fastened.

이는 상기 블레이드장착부(33)의 상하부에 각각 상부턱(331)과 하부턱(332)이 구비되어 있어, 상기 블레이드(321)를 상기 상부턱(331)과 하부턱(332)에 삽설하게 되면 이에 형성된 테이퍼부에 의해 상기 블레이드(321)의 상하면이 걸려지게 되고, 이때 상기 체결볼트(34)를 체결하게 되면 상기 절개홈(35)의 일단이 탄력적으로 눌려지는 텐션(tension)작용에 의해 상기 블레이드(321)가 견고하게 고정될 수 있게 된다. This is because the upper jaw 331 and the lower jaw 332 is provided at the upper and lower portions of the blade mounting portion 33, respectively, when the blade 321 is inserted into the upper jaw 331 and the lower jaw 332 The upper and lower surfaces of the blade 321 are caught by the formed taper, and when the fastening bolts 34 are fastened, one end of the cutting groove 35 is elastically pressed by the tension (tension) action. 321 can be firmly fixed.

상기와 같은 종래의 절삭공구체결홀더(30)는 공작물 가공시 블레이드에 많은 하중이 가해지게 되는데 이때 상기 블레이드가 접촉되는 접촉부위인 블럭이 쉽게 마모되게 된다. 이는 상기 절삭공구체결홀더(30)가 일체형으로 되어 있어 전체를 교환하여야 하고 이로 인한 경제적인 손실이 매우 크다.In the conventional cutting tool fastening holder 30 as described above, a large load is applied to a blade when a workpiece is processed, and the block, which is the contacting portion where the blade contacts, is easily worn. This is because the cutting tool fastening holder 30 is integrated, so that the whole must be replaced and the economic loss is very large.

또한 공작물 가공형태가 바뀔 경우 상기 블레이드를 해당 작업에 맞게 교환하여야 하는바, 이러한 블레이드의 빈번한 교환작업으로 상기 절개홈의 텐션기능이 약화되어 텐션작용에 의한 블레이드의 체결력이 떨어져 가공효율이 저하되는 문제가 있다.In addition, when the workpiece processing form is changed, the blade should be replaced according to the corresponding work. The frequent replacement of such blades weakens the tension function of the incision groove, and thus, the clamping force of the blade due to the tension action is reduced, thereby reducing the machining efficiency. There is.

이에 본 발명은 상기와 같은 문제를 해결하기 위해 안출된 것으로, 절삭공구 체결홀더를 공작기계에 장착되는 부분과 절삭공구를 장착하는 부분으로 나누어 분해 조립이 가능하도록 하고, 상기 절삭공구를 용이하게 탈·장착할 수 있도록 하는 테이퍼칩을 구비하여 줌으로써 절삭공구 체결홀더와 블레이드의 체결 및 교환 효율성을 획기적으로 향상시킬 수 있도록 된 절삭공구 체결홀더를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in order to solve the above problems, divided into a cutting tool fastening holder and a mounting portion for mounting the cutting tool and the mounting tool for disassembly and assembly, and easy to remove the cutting tool · The purpose of the present invention is to provide a cutting tool fastening holder which can improve the fastening and exchange efficiency of the cutting tool fastening holder and the blade by providing a taper chip for mounting.

상기와 같은 목적을 달성하기 위한 절삭공구 체결홀더는 공작기계나 선반의 클램프에 장착되는 고정몸체(11)와, 상기 고정몸체(11)에 체결볼트(12)로 장착되는 동시에 절삭공구(13)가 체결되는 절삭공구 체결몸체(14) 및 상기 절삭공구 체결몸체(14)의 상부측에 구비되면서 체결볼트(15)에 의해 상기 절삭공구(13)를 탈·장착할 수 있도록 된 테이퍼팁(16)으로 구성된 것을 특징으로 한다.Cutting tool fastening holder for achieving the above object is a fixed body 11 is mounted to the clamp of the machine tool or lathe, and the mounting tool (12) to the fixed body 11 at the same time cutting tool 13 Is provided on the cutting tool fastening body 14 and the upper side of the cutting tool fastening body 14 to which the taper tip 16 can be detached and mounted by the fastening bolt 15. It is characterized by consisting of).

따라서 본 발명에 따른 절삭공구 체결홀더는 고정몸체와 절삭공구 체결몸체 및 테이퍼팁이 별개로 구성되어 있어, 마모시 해당 부분만 교환할 수 있기 때문에 비용절감이 획기적으로 향상됨은 물론 블레이드 교환이 체결볼트에 의해 신속하고도 효율적으로 이루어지는 장점이 있다.Therefore, the cutting tool fastening holder according to the present invention is composed of a fixed body and the cutting tool fastening body and the taper tip separately, so that only the corresponding parts can be replaced when worn, as well as the cost savings significantly improved, as well as the fastening bolt blade replacement There is an advantage that is made quickly and efficiently by.
