본 고안은 다축 탭핑이나 다축 드릴링작업을 위해 드릴링 머신(MACHINE)에 부착하는 다축해드의 구조에 관한 것으로, 더축 구체적으로는 다축기의 기어박스 하단장치실에 장치되는 회전축의 구동기어 하측에 단턱을 만들어 와셔를 끼우고 와셔와 하측 베어링 사이에 코일스프링 장치하고 회전축의 구동기어가 치합되는 연결기어의 전달기어 길이를 상하로 현저히 길게하여 회전축이 승강하여도 치합상태가 유지되게 하므로서 드릴링 작업시에 드릴링 공구가 천공부에 끼이거나 작업시 드릴링공구에 무리한 저항이 가해지면 회전축이 상하로 미동하면서 저항을 해소시켜 공구의 파손을 방지하고 천공 작업속도를 높힐 수 있게 한 것이다.The present invention relates to the structure of a multi-axis head attached to a drilling machine (MACHINE) for multi-axis tapping or multi-axis drilling work, more specifically, the stepped bottom of the drive gear of the rotating shaft installed in the gearbox lower device room of the multi-axis machine. Make a washer, insert a coil spring between the washer and the lower bearing, and remarkably lengthen the transmission gear length of the connecting gear where the drive gear of the rotating shaft is engaged up and down to maintain the engagement state even when the rotating shaft is elevated. If the tool is caught in the drilling part or excessive resistance is applied to the drilling tool during the operation, the rotating shaft may move up and down to solve the resistance to prevent the damage of the tool and to increase the drilling speed.

종래의 드릴링 머신은 전달기와 치합하는 회전축의 구동기어가 일정위치에서 치합되어 있어서 회전축에 장착된 드릴링 공구로 피가공물에 천공작업을 한다음 천공부에서 공구를 빼낼때 공구가 천공부에 끼이게 되면 기계본체에 약간의 충격을 가하거나 요동시켜서 공구를 빼내게 되므로 공구가 쉽게 손상되고 수명이 단축될 뿐 아니라 작업속도도 느려지는 등의 결점이 있었다.In conventional drilling machines, the driving gear of the rotary shaft meshing with the transmitter is engaged at a certain position, and the drilling tool is mounted on the rotary shaft to drill the workpiece, and then the tool is caught in the drilling portion when the tool is removed from the drilling portion. Since the tool is removed by applying a slight impact or rocking to the machine body, the tool is easily damaged, shortened the lifespan, and the work speed is slowed.

본 고안은 위와 같은 종래의 결점을 해결하기 위해 고안된 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve the above conventional drawbacks and will be described in detail with reference to the accompanying drawings.

드릴링 머신 주축대(A) 하측으로 다축기(1)를 부착하여 그 연결관(3) 하단에 기어박스(2)를 장치하고 연결관(3) 내부에 원동축(A1)과 접속되는 종동축(5)을 설치하여 종동축(5) 하단의 기어(6)가 기어박스(2)에 설치된 연결기어(7)와 치합하며 연결기어(7)의 동일축선 하측에 형성된 전달기어(7a)는 기어박스(2) 하측 장치관(9)에 설치한 회전축(11)의 구동기어(10)에 치합하여 회전축(11)을 회전시킬 수 있게한 공지된 것에 있어서, 기어박스내의 연결기어(7)에 형성되는 전달기어(7a)는 그 길이를 현저히 길게하여 회전축(11)의 구동기어(10)가 치합상태에서 상하로 슬라이드될 수 있게하고 회전축(11)은 기어박스(2) 하부의 장치관(9)내에서 상·하측에 베어링(12)(13)을 끼워 장치하되 회전축(11)의 상측 축관부 하측에 단턱(11a)을 형성하여 와셔(14)를 끼운다음 와셔(14) 저부와 하부베어링(13) 사이에 코일스프링(15)을 끼워 회전축(11)이 탄력을 받으면서 승강되고 회전할 수 있게한 구조이다.Attached to the lower side of the drilling machine spindle (A), the multi-axis machine (1) is attached to the gear box (2) in the lower end of the connecting pipe (3) and the driven shaft connected to the driving shaft (A1) inside the connecting pipe (3) (5) is installed so that the gear 6 at the bottom of the driven shaft 5 meshes with the connecting gear 7 installed in the gear box 2, and the transmission gear 7a formed under the same axis of the connecting gear 7 is In connection with the drive gear 10 of the rotating shaft 11 provided in the lower apparatus pipe 9 of the gear box 2, the connecting gear 7 in the gear box is known. The transmission gear 7a formed in the shaft is made to lengthen remarkably long so that the drive gear 10 of the rotary shaft 11 can slide up and down in the engaged state, and the rotary shaft 11 is a device tube under the gear box 2. (9), the bearings 12 and 13 are inserted into the upper and lower sides, but the stepped portion 11a is formed below the upper shaft pipe part of the rotary shaft 11 to insert the washer 14, and then the bottom of the washer 14 and The coil spring 15 is sandwiched between the lower bearings 13 to allow the rotating shaft 11 to be lifted and rotated while receiving elasticity.

이와 같이된 본 고안은 드릴링머신을 작동시키고 주축대(A)를 하강시키면 드릴링공구(19)가 하강하여 피가공물(20)에 구멍을 형성하게 되고 이때 드릴링 공구에 가해지는 저항이 회전축(11)을 상승시켜 약간 상승된 위치에서 천공작업이 이루어지며 드릴링공구(19)를 뽑아낼때는 드릴링 공구가 천공부에 끼이게 되므로 주축대(A)가 상승할때 드릴링공구(19)는 제자리에 남으려는 힘이 생기게 되어 그것이 회전축(11)을 아래로 끌어 내리게 되고 동시에 회전축(11)의 단턱(11a)에 끼워진 와셔(14)를 통해 코일스프링(15)을 압축시키게 된다.When the drilling machine is operated and the main shaft A is lowered, the present invention as described above, the drilling tool 19 is lowered to form a hole in the workpiece 20, and the resistance applied to the drilling tool is the rotary shaft 11 When the drilling tool 19 is pulled out and the drilling tool 19 is pulled out, the drilling tool is caught in the drilling portion, so that the drilling tool 19 remains in place when the spindle A is raised. The force is generated so that it pulls down the rotating shaft 11 and simultaneously compresses the coil spring 15 through the washer 14 fitted in the step 11a of the rotating shaft 11.

따라서 코일스프링(15)은 긴장된 상태가 되고 즉시에 복원하려는 힘이 장진된다.Therefore, the coil spring 15 is in a tense state and the force to restore immediately is loaded.

따라서 코일스프링(15)의 복원력은 드릴링공구(19)가 피가공물의 천공부에 끼이는 힘보다 크게 설계되기 때문에 즉시 드릴링공구(19)를 상승시키려는 힘으로 작용하기 때문에 주축대를 하강시키는 힘이 제거되면 즉시 드릴링공구를 상승시키게 되므로 이러한 힘의 생성으로 인해 드릴링공구가 피가공물의 천공구멍속에 끼이는 일이 거의 없게 되어 천공작업이 용이하고 신속하게 되므로 공구를 보호할 수 있고 작업능률도 향상시킬 수 있는 이점을 얻게 되는 것이다.Therefore, since the restoring force of the coil spring 15 is designed to be larger than the force of the drilling tool 19 to be pinched in the perforated part of the workpiece, the force for lowering the main shaft is acted as a force to raise the drilling tool 19 immediately. As soon as it is removed, the drilling tool is raised immediately, so the generation of this force almost eliminates the drilling tool being caught in the drilled hole of the workpiece, making drilling easier and faster, thus protecting the tool and improving work efficiency. You will get the benefits.
