본 고안은 CNC 선바의 3축 제어를 구성하기 위하여 공구를 회전시키는 장치에 관한 것이다.The present invention relates to a device for rotating a tool to configure the three-axis control of the CNC sun bar.

더 상세하게는, 공구대에 설치된 각종 공구를 회전시키기 위한 구조와 동력전달 및 차단 기능을 부여함으로서 상대편의 주축에 척킹(chucking)된 공작물을 밀링 가공할 수 있도록 하려는 것이다.More specifically, it is intended to be able to mill the workpiece chucked (working) on the main shaft of the other side by providing a structure and power transmission and blocking functions for rotating the various tools installed on the tool post.

본 고안에 관련되는 3축 제어 CNC 선반에 관해서는 선출원된 특허출원 제 86-6758호에 기술된 바 있으며, 이의 주요 기능은 기존의 CNC 선반과는 달리 공구가 회전하면서 공작물의 모든 요소를 가공토록 하는 것이다.The three-axis control CNC lathe related to the present invention has been described in the previously filed patent application No. 86-6758, the main function of which is that unlike the conventional CNC lathe, the tool rotates to process all the elements of the workpiece. It is.

이 목적은, 종래의 선반이 수행할 수 없었던 밀링 가공 기능을 추가시킴으로서 CNC 선반의 단일기종만으로도 공작물에 대한 전반적인 가공을 달성할 수 있도록 연구된 것이었다.The purpose of this study was to add a milling function that a conventional lathe could not perform, so that a single machine of a CNC lathe could achieve the overall machining of a workpiece.

상기의 목적을 이룩하기 위해서는 공구대의 각종 공구가 자발적으로 회전되면서 상대편을 향하여 고정된 상태로 척킹된 공작물의 모든 가공부위를 자유롭게 가공할 수 있게 구성하는 것이다.In order to achieve the above object, various tools of the tool bar are spontaneously rotated so as to be able to freely process all the machining portions of the workpiece chucked in a fixed state toward the other side.

이하, 본 고안의 구조 및 작용을 첨부된 도면과 관련하여 상세히 설명하면 명백히 이해될 것이다.Hereinafter, the structure and operation of the present invention will be clearly understood with reference to the accompanying drawings in detail.

제1도는 본 고안의 적용되는 3축 제어 CNC 선반의 주요기능에 대한 개략 구성도로서 ＂A＂ 부분이 본 고안에 해당된다.1 is a schematic configuration diagram of the main functions of the three-axis control CNC lathe to which the present invention is applied.

즉, 공구대에 설치된 각종 공구가 선택되었을 때 제어부의 신호에 의하여 가공선상에 이르러 회전동력을 전달방게 되는 구성을 보인 것으로 그 구체적인 구성은 제2도 및 제3도와 같다.That is, when the various tools installed on the tool bar is selected, the rotational power is transmitted to the cutting line by the signal of the control unit. The specific configuration is shown in FIGS. 2 and 3.

모터(M)의 회전력이 벨트(1)를 통하여 구동기어(2)로 전달되고, 이외 구동축(3)은 베어링(4)(4')으로 유지되며, 내부에 스프링(5)이 탄입되어 종방향으로 키이(6) 및 키이홈이 결합된 완충축(7)을 구성하되, 선단에는 요철면을 갖는 클러치(8)를 형성하여 선택된 공구(t)의 클러치(9)가 접탈되도록 하고, 회전공구의 케이스(c) 내부에는 베어링(10)(10')(10'')으로 유지되는 2축(13)(14)을 구성하여 동력이 전달되도록 각각의 기어(11)(12)를 치합시켜서 된 것이다.The rotational force of the motor M is transmitted to the drive gear 2 through the belt 1, the other drive shaft 3 is maintained as a bearing (4) (4 '), the spring (5) inside the ball And a shock absorbing shaft (7) in which the key (6) and the key groove are coupled in the direction, and the clutch (8) having the uneven surface is formed at the front end thereof so that the clutch (9) of the selected tool (t) is detached and rotated. Inside the case c of the tool, two gears 13 and 14 are held by bearings 10, 10 'and 10 " to engage the respective gears 11 and 12 to transmit power. It was made.

이와 같이 구성된 본 고안은, 제어부(도시없음)의 신호에 의하여 공구(t)가 선택되면 공구대(k)가 회전하여 해당공구를 가공선상으로 위치 시키게 된다. 곧이어, 공구대(k)가 후퇴하여 선택된 공구(t)를 구동축(3)에 접속시키면 공구(t)의 후단에 있는 클러치(9)가 완충축의 클러치(8)와 결합되며, 이때의 상호간에 대한 충격은 완충축(7)이 후퇴되면서 상쇄될 수 있다.According to the present invention configured as described above, when the tool t is selected by a signal of a controller (not shown), the tool stage k is rotated to position the tool on the cutting line. Subsequently, when the tool post k is retracted and the selected tool t is connected to the drive shaft 3, the clutch 9 at the rear end of the tool t is engaged with the clutch 8 of the shock absorbing shaft. The impact on the vehicle may be offset by the retraction of the buffer shaft 7.

동시에 모터(M)가 동작하여 구동기어(2)를 회전시키고 구동축(3) 및 완충축(7)을 통하여 클러치(8)(9)로 이어진 공구측의 축(13)(14)과 기어(11)(12)를 회전시킴으로서 공구(t)의 회전이 이루어지게 되는 것이다.At the same time, the motor M operates to rotate the drive gear 2, and the shafts 13 and 14 and the gears on the tool side which are connected to the clutches 8 and 9 through the drive shaft 3 and the buffer shaft 7. 11) by rotating the tool 12 is to be rotated.

상기의 동력전달을 위한 클러치(8)(9)의 결합시에 있어서, 요철면의 결속이 단번에 이루어지지 않더라도 모터(M)가 구동되면서 완충축(7)에 회전력이 발생되면 스프링(5)력으로 탄압된 상태에 놓여 있게 되므로 회전이 시작됨과 동시에 즉시 결합될 수 있다.At the time of engagement of the clutches 8 and 9 for power transmission, the spring 5 force is generated when the rotational force is generated on the buffer shaft 7 while the motor M is driven even though the uneven surface is not engaged at once. It is placed in a suppressed state so that it can be immediately combined with the start of rotation.

이상과 같은 본 고안은 공구를 선택하여 해당공구의 회전력을 부여함에 있어서, 동력전달 및 차단동작이 확실하게 일어나며, 접촉시의 완충 용이한 결속에 의하여 3축 제어 CNC 선반의 목적을 달성할 수 있는 회전공구 장치를 제공하게 되는 것이다.The present invention as described above, when the tool is selected to give the rotational force of the tool, the power transmission and interruption action occurs reliably, and by the easy binding of the buffer during contact can achieve the purpose of the three-axis control CNC lathe It is to provide a rotary tool device.
