Cutting formed to extend to the upper portion of the fixed chuck 9 and is mounted to protrude with a predetermined inclination angle from the outer peripheral surface of the fixed chuck 9 to the shaft portion 10 and the fixed recessed portion (8) inserted into the main shaft of the drill machine Chamfer consisting of bite 11 It has a material (12).

또한, 상기한 모떼기부재(12)의 축부(10)는 상기 고정척부(9)보다 작은 직경을 가지며 고정척부(9)와 단부(13)를 이루도록 연장형성되며 상기 축부(10)의 일부위에는 나사부(14)가 구비되고, 상기 단부(13)에 베어링(15)과 상기 나사부(14)에 나사고정되는 너트체(16)에 의해 공회전되도록 고정되며 상기 고정척부(9)의 외주면이 밀착 삽입되는 수용부(17)가 형성되고 상단은 상기 축부(10)의 외경크기의 삽착공(18)이 마련된 턱(19)을 가지는 관상의 지지부재(20)를 가지고 있다.In addition, the shaft portion 10 of the chamfering member 12 has a smaller diameter than the fixed chuck portion 9 and is formed to extend to form the fixed chuck portion 9 and the end portion 13 and on a portion of the shaft portion 10. A threaded portion 14 is provided and fixed to the end 13 by a bearing 15 and a nut body 16 screwed to the threaded portion 14, and the outer circumferential surface of the fixing chuck 9 is tightly inserted. The receiving portion 17 is formed and the upper end has a tubular support member 20 having a jaw 19 provided with the insertion hole 18 of the outer diameter size of the shaft portion 10.

이와 같이 이루어지는 본 발명의 렌치볼트용 홀 절삭공구(1)는 도 3 내지 도 6에서 도시된 바와 같이 드릴머신의 주축(21)에 장착고정되어 센터구멍이 형성된 공작물(m)의 센터구멍에 드릴링하여 한 공정으로 나사탭을 형성하기 위한 렌치볼트구멍과 렌치볼트머리홈과 모떼기 작업을 수행하게 되어 있다.As described above, the wrench bolt hole cutting tool 1 of the present invention is mounted on the main shaft 21 of the drill machine and drilled in the center hole of the work piece m having a center hole, as shown in FIGS. In this process, the wrench bolt hole, the wrench bolt head groove, and the chamfering work for forming the screw tab are performed.

이와 같은 것은 도면에서 표현된 바와 같이 먼저 드릴머신의 주축(21)에 모떼기부재(12)의 축부(10)를 삽착하여 드릴머신에 본 발명의 렌치볼트용 홀 절삭공구(1)를 고정하고 센터구멍이 형성된 공작물(m)의 센터구멍을 중심으로 회전하면서 하강시키면 도 6에서 도시된 바와 같이 먼저 드릴부재(6)의 비틀림홈(2)에 의해 드릴구멍(h)이 공작물(m)에 형성되고 절삭공구(1)를 더욱 하강시키면 렌치볼트머리홈 절삭날(5)에 의해 상기 드릴구멍(h)의 상측의 직경이 확장되어 렌치볼트머리의 수용 공간인 렌치볼트머리홈(s)이 생성된다.As such, as shown in the drawings, the shaft 10 of the chamfering member 12 is first inserted into the main shaft 21 of the drill machine to fix the hole cutting tool 1 for the wrench bolt of the present invention. When the center hole is formed while descending while rotating about the center hole of the work m, the drill hole h is first introduced into the work piece m by the torsion groove 2 of the drill member 6, as shown in FIG. When the cutting tool 1 is further lowered, the diameter of the upper side of the drill hole h is expanded by the wrench bolt head groove cutting edge 5 so that the wrench bolt head groove s, which is an accommodation space of the wrench bolt head, is formed. Is generated.

상기와 같이 렌치볼트머리홈(s)이 형성된 후 더욱 계속하여 절삭공구(1)를 더욱 하강시키면 모떼기부재(12)의 고정척부(9)에 고정된 절삭바이트(11)에 의해 렌치볼트머리홈(s)의 상단 내주면에 일정한 각도로 파여 모떼기(r)처리가 되어 작업이 완료된다.After the wrench bolt head groove s is formed as described above, if the cutting tool 1 is further lowered further, the wrench bolt head is cut by the cutting bit 11 fixed to the fixed chuck 9 of the chamfering member 12. Work is completed by digging at a predetermined angle on the upper inner peripheral surface of the groove (s) (r).

이와 같이 공작물(m)에 렌치볼트머리홈(s)과 드릴구멍(h)과 모떼기(r)작업이 완료되면 절삭공구(1)를 상승시키어 공작물(m)에서 이탈을 시키고, 또다른 공작물을 드릴머신의 홀더에 고정시킨후 상기와 같은 방법을 순차적으로 수행하여 계속해서 공정을 수행하면 된다.Thus, when the wrench bolt head groove (s), the drill hole (h) and the chamfer (r) work is completed on the workpiece (m), the cutting tool (1) is raised to separate from the workpiece (m), and another workpiece After fixing to the holder of the drill machine may be carried out by continuing the process by performing the same method sequentially.

물론 상기에서 모떼기부재(12)의 고정척부(12)에 상기한 지지부재(20)를 마련하여 작업을 수행하면 특히 핸드드릴링 머신의 이용시에 센터의 중심에서 절삭공구의 회전축심이 이동을 하지 않도록 하면서 하강하여 작업을 함으로써 보다 정확하고 안정되게 작업을 수행할 수가 있다.Of course, when the support member 20 is provided on the fixed chuck 12 of the chamfering member 12 to perform the operation, the rotation axis of the cutting tool is not moved in the center of the center, especially when using the hand drilling machine. By working while descending, you can work more accurately and reliably.

상기한 바와 같이 본 발명의 렌치볼트용 홀 절삭공구는 여러개의 공구를 순차적으로 탈부착하여 각각의 공정을 수행하지 않고 한번의 탈부착과 작업을 통하여드릴링공정과, 렌치볼트머리홈공정과 모떼기공정을 수행할 수 있어 작업이 간편하고 작업시간이 적게 소요되는 등 그 제작공정을 능률적으로 수행하므로써 생산성이 향상되고 경제적인 효과가 있다.As described above, the wrench bolt hole cutting tool of the present invention performs a drilling process, a wrench bolt head groove process, and a chamfering process through a single detachment and work without performing each process by detaching and attaching several tools sequentially. Because it can be performed, the work is simple and the working time is short, so that the production process is performed efficiently, thereby improving productivity and economic effect.
