본 발명은 터렛이 장착된 공작기계에서 공작물을 지지하기 위한 지지장치에 관한 것으로, 특히 터렛에 공작물의 방진을 위해 장착된 간이형 방진구에 관한 것이다.The present invention relates to a support device for supporting a workpiece in a machine tool equipped with a turret, and more particularly, to a simple dustproof device mounted for dust protection of a workpiece in a turret.

종래 공작기계는 도 1과 같이 대향형 주축에서 긴 공작물을 가공하고자 할 경우 종래에는 서보구동 방진구(auto centering)(5)를 사용한다. 서보구동 방진구(5)는 주축의 하부에서 주축과 나란한 방향으로 이동가능하게 설치되어 있다.Conventional machine tools conventionally use a servo-driven anti-vibration (auto centering) (5) if you want to machine long workpieces on the opposite spindle as shown in FIG. The servo drive vibration isolator 5 is provided so as to be movable in the direction parallel to the main axis in the lower part of the main axis.

따라서 공작물(W)의 길이가 긴 경우 서보구동 방진구를 공작물에 지지시켜서 공작물의 선삭시 발생되는 회전 진동을 억제하게 되어 있다.Therefore, when the length of the workpiece | work W is long, the servo drive antivibration support is supported by a workpiece | work, and the rotational vibration which arises at the time of turning of a workpiece | work is suppressed.

선삭가공과 함께 밀링, 드릴링 가공을 수행하는 복합가공기의 경우 해당 가공에 필요한 공구를 선택할 수 있도록 터렛(turret)을 갖는다. 따라서 터렛을 적용하는 경우 종래와 같이 서보구동 방진구를 사용할 수 없는 문제가 있다. 즉, 터렛이 주축의 하방에 배치된 경우 종래의 서보구동 방진구를 사용할 수 없는 것이다.In the case of a multi-task machine that performs milling and drilling along with turning, it has a turret to select a tool for the machining. Therefore, when the turret is applied, there is a problem in that the servo drive vibration isolation device cannot be used as in the prior art. That is, when the turret is disposed below the main shaft, it is impossible to use a conventional servo drive anti-vibration port.

따라서 본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위한 것으로, 터렛이 설치된 공작기계에서 긴 공작물을 가공시 발생되는 진동을 억제하기 위한 터렛 장착 간이형 방진구를 제공함에 그 목적이 있다.Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to provide a turret-mounted simple dustproof tool for suppressing vibration generated when machining a long workpiece in a machine tool having a turret.

상기의 목적을 달성하기 위한 본 발명의 구체적인 수단은,Specific means of the present invention for achieving the above object,

대향되는 양 주축의 하부에 공구가 장착되는 터렛을 구비한 공작기계에 있어서, In a machine tool having a turret in which a tool is mounted on a lower portion of opposite main shafts,                         

상기 터렛의 헤드 외주면에 일단이 장착되는 롤러 지지용 브래킷과;A roller support bracket having one end mounted on an outer circumferential surface of the turret;

상기 롤러 지지용 브래킷의 타단 양단에 축지되어 공작물의 회전을 구름운동으로 지지하는 베어링수단과;Bearing means which is supported at opposite ends of the roller support bracket to support rotation of the workpiece by rolling motion;

상기 베어링수단을 상기 롤러 지지용 브래킷에 지지하도록 상기 주축과 나란하게 설치된 지지축을 포함한 것을 특징으로 한다.And a support shaft installed in parallel with the main shaft to support the bearing means on the roller support bracket.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 터렛에 장착된 간이형 방진구의 사시도이고, 도 3은 본 발명의 터렛에 장착된 간이형 방진구의 사용상태도이다.Figure 2 is a perspective view of a simple dustproof device mounted on the turret of the present invention, Figure 3 is a state diagram of a simple dustproof device mounted on the turret of the present invention.

도 2,3에서와 같이 대향되는 양 주축(12,14)의 하부에 공구가 장착되는 터렛(20)을 갖는 공작기계에 있어서, 상기 터렛(20)의 헤드 외주면에 간이형 방진구(30)가 장착되어 있다.In a machine tool having a turret 20 in which a tool is mounted on both opposing main shafts 12, 14 as shown in FIGS. Is equipped.

상기 간이형 방진구(30)는 롤러지지용 브래킷(32)과, 베어링수단(34), 베어링수단(34)을 롤러지지용 브래킷(32)에서 지지하는 지지축(36)으로 구성되어 있다.The simple anti-vibration opening 30 is composed of a roller support bracket 32, a bearing means 34, and a support shaft 36 for supporting the bearing means 34 in the roller support bracket 32. As shown in FIG.

상기 롤러지지용 브래킷(32)은 터렛 헤드의 외주면에 장착되는 평탄한 베이스부(32a)와 이 베이스부(32a)의 중앙에서 입설된 수직부(32b)로 구성되어 있고, 수직부(32b)의 양단에는 축지지공(33)이 형성되어 있다.The roller support bracket 32 is composed of a flat base portion 32a mounted on the outer circumferential surface of the turret head and a vertical portion 32b mounted at the center of the base portion 32a. Axial support holes 33 are formed at both ends.

상기 축지지공(33)에는 상기 주축(12 또는 14)과 나란한 지지축(36)이 설치되고, 상기 지지축(36)에는 공작물의 회전을 구름운동으로 지지하는 베어링수단 (34)이 설치되어 있다.The shaft support hole 33 is provided with a support shaft 36 in parallel with the main shaft 12 or 14, and the support shaft 36 is provided with bearing means 34 for supporting the rotation of the workpiece in rolling motion. .

본 실시예에서 베어링수단은 롤러베어링으로 구성하였으나 본 발명은 롤러 베어링에 한정되는 것은 아니며 In the present embodiment, the bearing means is composed of a roller bearing, but the present invention is not limited to the roller bearing.

이와 같이 구성된 본 실시예의 작용을 설명한다.The operation of this embodiment configured as described above will be described.

도 3과 같이 공작물(W)이 긴 경우 터렛(20)에는 본 발명의 방진구(30)가 설치된다.When the workpiece W is long as shown in Figure 3, the turret 20 is provided with a dustproof port 30 of the present invention.

먼저, 롤러지지용 브래킷(32)의 베이스(32a)를 4개소에 각기 볼트(40)를 이용하여 터렛(30)의 헤드 외주면에 장착한다. 이렇게 되면 터렛(20)은 롤러지지용 브래킷(32)에 설치된 한쌍의 롤러베어링(34)을 갖게 된다.First, the base 32a of the roller support bracket 32 is attached to the head outer peripheral surface of the turret 30 using the bolt 40 in each place. In this case, the turret 20 has a pair of roller bearings 34 installed on the roller support bracket 32.

가공 프로그램에 의해 방진구(30)는 공작물에 가까운 위치로 설정되고, 터렛(20)의 위치 제어에 의해 한쌍의 롤러 베어링(34)은 공작물에 면접촉하게 된다.The dustproof opening 30 is set to a position close to the workpiece by the machining program, and the pair of roller bearings 34 are in surface contact with the workpiece by the position control of the turret 20.

이 상태에서 주축(12)의 회전 구동에 의해 공작물이 회전되면 공작물에 접촉된 롤러베어링(34)도 동시에 회전을 하게 되고, 이때 공작물에서 발생되는 진동은 롤러지지용 브래킷(32)을 매개로 터렛(20)에서 억제하게 되고, 그 결과 공작물이 가공중 휘어지거나 부러지는 일은 물론 진동 발생을 억제하게 된다.In this state, when the workpiece is rotated by the rotational drive of the spindle 12, the roller bearing 34 in contact with the workpiece is also rotated at the same time, and the vibration generated in the workpiece is the turret through the roller support bracket 32. At 20, as a result, the workpiece is not only bent or broken during processing, but also the vibration is suppressed.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

상술한 바와 같이 본 발명의 터렛 장착 간이형 방진구에 따르면, 종래의 서브구동 방진구가 없이도 주축의 하부에 배치된 터렛에 설치된 지지장치로서 긴 공작물의 가공중 발생되는 진동이나 휨을 억제할 수 있다. As described above, according to the turret-mounted simple anti-vibration device of the present invention, it is possible to suppress vibrations and warpage generated during the processing of long workpieces as a support device installed on the turret disposed under the main shaft without the conventional sub-driven anti-vibration port. .
