본 발명은 장축 공작물을 지지하는 장치에 관한 것으로, 특히 대향형 주축을 가진 CNC선반에서 서브스핀들에 설치되어 가공완료된 장축의 공작물을 지지하여 외부로 배출안내하는 장치에 관한 것이다. The present invention relates to a device for supporting a long-axis workpiece, and more particularly, to a device for supporting the finished long-axis workpiece to be discharged to the outside installed on the subspindle in the CNC lathe having an opposing spindle.                         

종래 메인스핀들(1)과 서브스핀들(2)이 서로 대향하게 배치된 CNC선반은 도 1에 도시된 바와 같이, 가공완료된 장축의 공작물(W)을 장비 외측에 구비된 테이블(도시생략함)로 배출시키기 위하여 그 서브스핀들(2)에, 가공완료된 장축의 공작물을 장비 외측으로 안내하는 긴 가이드튜브(8)가 설치된다.Conventionally, a CNC lathe in which main spindles 1 and subspins 2 are disposed to face each other is provided with a table (not shown) provided with a workpiece W having a long axis, as shown in FIG. In order to discharge, the subspindle 2 is provided with an elongated guide tube 8 for guiding the finished long axis workpiece out of the machine.

그런데 상기 종래의 가이드튜브(8)는 일정한 직경을 가진 1개의 튜브만으로 이루어져 있으므로 직경이 다른 공작물을 가공할 때에는 그 공작물을 안내하기에 적합한 다른 직경의 가이드튜브로 교체하여야 한다. 그러나 대향형 주축을 가진 CNC선반은 구조가 아주 복잡하여 서브스핀들에 장착된 가이드튜브를 다른 가이드튜브로 교체하는 작업이 까다롭고 시간이 많이 소요되며, 특히 분해조립작업이 어려우므로 숙련자만이 가능하였다. However, since the conventional guide tube 8 consists of only one tube having a constant diameter, when machining a workpiece having a different diameter, it should be replaced with a guide tube having a different diameter suitable for guiding the workpiece. However, CNC lathes with opposing spindles are very complicated in structure, which makes it difficult and time-consuming to replace the guide tubes mounted on the subspindles with other guide tubes. .

이에 본 발명은 상기 종래의 장축공작물 지지장치가 가진 문제점을 해소하기 위하여 고안된 것으로, 가공되는 공작물의 직경에 대응하는 튜브로 교체하는 작업이 간단하고 용이하여 비숙련공이라도 간단하고 정확하게 교체작업이 가능한 장축 공작물 지지장치를 제공함에 목적이 있다. The present invention is designed to solve the problems of the conventional long-axis workpiece support device, it is easy and easy to replace the tube corresponding to the diameter of the workpiece to be processed long axis that can be replaced easily and precisely even unskilled workers It is an object to provide a workpiece support device.

상기 목적을 달성하기 위한 본 발명은 주축과 동심축상에서 서로 대향하는 서브스핀들의 중심축방향으로 관통삽입되고 다수개의 서로 다른 직경의 긴 튜브들이 서로 동심축으로 슬라이드결합되고, 이들 복수개의 튜브들의 선단에는 결합링부재가 끼워져 각각의 체결나사로써 각각의 튜브들을 고정하게 되게 되어 있다. The present invention for achieving the above object is inserted through the central axis direction of the sub-spindle opposite to each other on the main axis and the concentric axis and a plurality of long tubes of different diameters are slide-coupled concentrically with each other, the tip of the plurality of tubes The coupling ring member is fitted to fix each tube with each fastening screw.

상기한 바와 같은 구조로 된 본 발명에 의해 다른 직경의 공작물을 가공하는 경우 복수개의 튜브들 선단에 결합된 결합링부재로부터 체결나사를 풀어 가공공작물의 직경에 대응하는 튜브를 서브스핀들의 중앙 관통구멍안으로 관통삽입시키면 간단히 튜브가 교체된다. 이로써 튜브교체에 따른 작업시간을 줄이고, 작업도 간편하며 튜브의 중심과 주축의 중심이 이미 맞추어져 있으므로 튜브교체시 중심맞추기 작업을 할 필요가 없어 가공공작물 직경변경에 따른 장비셋팅시간을 대폭 줄일 수 있다. When machining workpieces of different diameters according to the present invention having the structure as described above, loosen the fastening screw from the coupling ring member coupled to the ends of the plurality of tubes and open the tube corresponding to the diameter of the workpiece to the center through hole of the subspindle. Penetrating in simply replaces the tube. This reduces work time due to tube replacement, eases work, and the center of the tube and the center of the spindle are already aligned, eliminating the need for centering when replacing the tube. have.

이하, 본 발명에 따른 실시예를 첨부도면에 따라 상세히 설명한다.Hereinafter, embodiments according to the present invention will be described in detail according to the accompanying drawings.

도 1은 본 발명에 따른 장축 공작물의 지지장치가 설치되는 복합가공용 CNC선반의 개략적인 구조를 도시한 도면이다. 복합가공용 CNC선반은, 도 1에 도시된 바와 같이, 봉상의 재료를 물어서 회전시키는 메인스핀들(1)과 동일한 중심축상에 서브스핀들(2)이 상기 메인스핀들(1)과 서로 마주보게 배치되고, 상기 메인스핀들(1)과 서브스핀들(2)의 사이에는 복수개의 절삭공구(3)들이 원주상에 고정설치된 터렛(4)이 설치된다. 1 is a view showing a schematic structure of a CNC lathe for multi-processing is installed, the support device for a long-axis workpiece according to the present invention. In the CNC machining for multi-processing, as shown in FIG. 1, the subspins 2 are disposed to face the main spins 1 on the same central axis as the main spins 1 for biting and rotating the rod-like material. Between the main spins 1 and the subspins 2, a turret 4 is installed in which a plurality of cutting tools 3 are fixed on a circumference.

여기서 본 발명에 따른 공작물 지지장치(10)는, 도 2에 도시된 바와 같이,상기 서브스핀들(2)의 중심축 방향으로 관통된 관통구멍에 서로 다른 내경을 가진 복수개의 공작물 안내튜브(11,12,13)들이 조립되어 설치되고, 장비 외측으로 돌출된 상기 공작물 안내튜브(11,12,13)들의 선단에는 이들 공작물 안내튜브(11,12,13)들의 선단들을 한꺼번에 수용하는 결합링부재(15)가 끼워져 결합되고, 이 결합링부재(15)의 측벽을 가로질러 관통하는 체결나사(16)들이 결합링부재(15)안에 삽입되어 있는 공작물 안내튜브(11,12,13)들을 각각 고정하거나 고정해제하게 되어 있다. Here, the workpiece support device 10 according to the present invention, as shown in Figure 2, a plurality of workpiece guide tube 11 having a different inner diameter in the through hole penetrated in the direction of the center axis of the sub-spindle (2), 12, 13 are assembled and installed, the coupling ring member for accommodating the front ends of the workpiece guide tubes (11, 12, 13) at the front end of the workpiece guide tubes (11, 12, 13) protruding out of the equipment ( 15 is fitted and coupled, and fastening screws 16 penetrating across the side wall of the coupling ring member 15 fix the workpiece guide tubes 11, 12, 13 inserted in the coupling ring member 15, respectively. Or to be unlocked.

그리고 상기 복수개의 공작물 안내튜브(11,12,13)들은 적당한 위치마다 튜브홀더(17)로써 지지된다. The plurality of workpiece guide tubes 11, 12, 13 are supported by tube holders 17 at appropriate positions.

상기한 바와 같이 구성된 본 발명에 따르면, 일정한 직경을 가진 공작물을 가공완료한 후, 다른 직경의 공작물을 가공하고자 하는 경우에 이미 서브스핀들(2)에 설치된 공작물 안내튜브(11,12,13)를 변경된 직경에 알맞은 내경의 공작물 안내튜브(11,12,13)로 교체하여야 하는 데, 이 때 결합링부재(15)의 체결나사(16)를 풀고 기존 사용했던 공작물 안내튜브(11,12,13)를 장비 외측으로 끌어낸 다음, 교체하고자 하는 다른 직경의 안내튜브(11,12,13)를 서브스핀들(2)의 관통구멍안으로 밀어 넣고, 결합링부재(15)를 끼워 다시 체결나사(16)로 고정한다. According to the present invention configured as described above, after processing a workpiece having a constant diameter, the workpiece guide tube (11, 12, 13) already installed in the sub-spindle (2) in the case of processing a workpiece of a different diameter The guide tube (11, 12, 13) of the inner diameter suitable for the changed diameter should be replaced. At this time, loosen the fastening screw (16) of the coupling ring member (15) and the workpiece guide tube (11, 12, 13) ), The guide tubes 11, 12 and 13 of different diameter to be replaced are pushed into the through holes of the subspindle 2, and the coupling ring member 15 is inserted again to tighten the screw 16 )

그리고 나서 장비를 가동하여 가공작업을 하고 가공완료된 공작물은 서브스핀들(2)에 장착된 공작물 안내튜브(11,12,13)안으로 들어가게 되며, 이러한 공정을 반복함에 따라 공작물 안내튜브(11,12,13)에 일렬로 채워져 있는 가공완료된 공작물을 후속하여 진입하는 공작물에 점차 밀려서 순차적으로 장비 외측의 테이블로 배출되게 된다. 이러한 작동은 종래의 공작물 안내장치와 동일하다. Then, the machine is operated and machined, and the finished workpiece enters into the workpiece guide tubes 11, 12, and 13 mounted on the subspindles 2, and the workpiece guide tubes 11, 12, The finished workpieces, which are filled in line in 13), are gradually pushed by the subsequent entering workpieces and sequentially discharged to the table outside the equipment. This operation is the same as a conventional workpiece guide.

상기한 바와 같이 구성된 본 발명은 하나의 작업이 끝나고 다른 직경의 공작물을 가공할 때, 그 공작물을 배출안내하기에 적합한 새로운 안내튜브를 교체하는 데 커버를 분해조립하거나 튜브교체후 다시 중심맞추기 작업등을 할 필요가 없으므 로 장비 재셋팅에 소요되는 시간을 대폭 단축하여 생산성을 향상시킬 수 있고, 비숙련공이라도 어려움없이 튜브를 정확하게 교체할 수 있는 장점이 있다.According to the present invention configured as described above, when machining a workpiece of different diameter after finishing one operation, disassembling or replacing the cover to replace a new guide tube suitable for ejecting the workpiece, or realigning the tube after replacing the tube, etc. Since there is no need to do this, the time required for the equipment reset can be drastically shortened, thereby improving productivity, and even an unskilled worker can change the tube accurately without difficulty.
