본 발명은 와이어와 공작물과의 사이에서 불꽃방전을 시킴과 동시에 공작물을 목적으로 하는 형태에 따라 이동시키면서 가공하는 와이어 컷트 방전 가공기에 있어서 보빈(Bobbin)축을 보빈의 폭에 관계없이 설치할 수 있도록 구성된 보빈축 및 그의 취부 구조에 관한 것이다.The present invention provides a beam configured to install a bobbin axis irrespective of the bobbin width in a wire cut electric discharge machine for processing while discharging a spark discharge between a wire and a workpiece and simultaneously moving the workpiece according to a desired shape. It relates to a hollow shaft and its mounting structure.

종래에는 제 3 도에서 보는 바와같이 보빈축(31')의 길이가 한정되어 있어서 이에 알맞는 폭의 보빈 밖에는 사용할 수 없는 제한성이 있었다. 따라서 와이어의 이송량이 많은 작업이라 적은 작업에도 항상 동일한 크기의 보빈(30)을 사용하므로서 와이어의 이송량이 많은 작업시에는 해당량을 모두 수용하지 못하여 번번히 교체해야 하는 문제점이 있었으며, 반대로 적은 작업시에는 보빈(30)의 전부를 활용치 못하고 일부분만이 활용 되므로서 비 경제적이고 비 능률적인 요소가 많았다. 또한 보빈축(31)의 고정이 제 1 도와 같이 한쪽으로만 고정되어 있어 보빈축(31)에 부하가 걸린 상태에서 회전을 하게 되므로 처짐이 발생되며, 고속 회전시에는 원심력에 의하여 축선을 벗어나게 되어 진동과 소음이 발생됨과 동시에 보빈축(31)의 굽힙이 발생되는 정적 평형의 불균형으로 인해 와이어의 이송속도가 불규칙하게 이루어져 정밀 가공에 많은 오차가 생길 수 있었다.Conventionally, as shown in FIG. 3, the length of the bobbin shaft 31 'is limited, and only a bobbin having a suitable width can be used. Therefore, since the bobbin 30 of the same size is always used even for a small amount of work because of a large amount of wire feeding, there was a problem that the quantity cannot be accommodated in the case of a large amount of wire feeding. Since only a part of the bobbin 30 was not used, there were many inefficient and inefficient factors. In addition, since the bobbin shaft 31 is fixed to only one side as the first diagram, the bobbin shaft 31 is rotated while the load is applied to the bobbin shaft 31, and sag occurs. Due to the imbalance of static equilibrium in which the vibration and noise are generated and the bending of the bobbin shaft 31, the feeding speed of the wire is irregular, which may cause a lot of errors in precision machining.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위한것으로서 축의 길이를 조절 하도록 구성하고 또한 양단에는 축의 지지점을 부여 하므로서 상기에 기술한 불 완전한 요소를 해소 시킨 것이다.The present invention is to solve the conventional problems as described above is to adjust the length of the shaft and to solve the incomplete element described above by giving a support point of the shaft at both ends.

본 발명을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

기판(15)상에 보빈축(2) 및 보빈(1)을 축으로 설치할 수 있는 지지대(18)(18')를 설치함에 있어서 일측지지대(18)에는 축지지흠을 형성하여 내부에 부시가 결합된 볼 베어링(6), 코일 스프링(9)순으로 설치하고, 타측 지지대(18')에는 힌지(13)를 체결점으로 하는 회동간(19)을 설치하되 상부에 부시가 결합된 볼 베어링(6'), 지지판(11), 판스프링(10)순으로 설치하며 그 하부 주변에는 잠금수단을 갖도록 하기 위하여 힌지(13')로 결합된 감금판(20)을 구성하고, 상부에는 레버(12), 축부에는 롤러(17)를 구성하며 상기의 양측 베어링 지지부에 대하여 보빈축(2)을 설치하되 일측은 고정판(5)을 형성하고 타측은 스크류(3)를 형성하여 조절너트(4)를 나사상으로 이동케 하므로 공지의 보빈축을 고정 시키도록 구성한 것이다.In installing the support 18 and 18 'which can install the bobbin shaft 2 and the bobbin 1 as the shaft on the board | substrate 15, the one side support 18 forms a shaft support flaw, and a bush is formed inside. The ball bearing 6, the coil spring (9) is installed in order, and the other side of the support (18 ') is provided with a pivoting period (19) having a hinge 13 as a fastening point, but the bush is coupled to the upper ball bearing (6 '), the support plate 11, the leaf spring (10) in order to install a confinement plate 20 coupled by a hinge (13') in order to have a locking means around the lower portion, the upper lever ( 12), a roller 17 is formed in the shaft portion, and the bobbin shaft 2 is installed on both bearing support portions, one side of which forms a fixing plate 5 and the other side of which forms a screw 3 to adjust the adjusting nut 4. It is configured to fix the known bobbin shaft because it moves on the screw.

위와같은 본 발명은 보빈(1)을 축상에 수평으로 지지시킴에 있어서 양측 지지점을 제공하므로 진동 및 떨림 발생이 방지되며 본 발명에 의하여 보빈의 설치 방법을 설명하면 아래와 같다.As described above, the present invention provides both support points in supporting the bobbin 1 horizontally on the shaft, thereby preventing the occurrence of vibration and vibration, and explaining the installation method of the bobbin according to the present invention.

양측힌지의 고정 볼트(14)(14')를 풀고 레버(12)를 우측 아래로 당기면 회동간이 힌지(13)를 중심으로 우측으로 기울게되어 보빈축의 타측이 개방되어 보빈축(2)에 보빈을 끼우고 조절 너트(4)을 조임으로서 보빈(1)이 고정되고 회동간(19)을 상승시켜 보빈축(2)의 타측과 조립 지지되며 레버(12)를 상승시키면 잠금판 힌지(13') 앞쪽의 롤러(17)가 회동간(19)의 벽면을 밀게 되어 고정 되면 양 힌지(13)(13')의 고정 볼트(14)(14')를 조여 고정하게 된다. 이때 양 지지부의 코일 스프링(9)과 판스프링(10)은 보빈(1)의 설치시 충격을 완화시키며 보빈축(2)의 회전시 양 부쉬(7)(7')의 풀림을 방지하게 된다. 따라서 본 발명은 종래의 것 보다는 달리 보빈축(2)이 양쪽으로 지지되므로서 회전에 대한 정적평형이 불균형이 나타나지 않아 회전 속도에 균일하며 정밀 가공을 할 수 있으며 작업량에 알맞는 보빈을 사용함으로서 경제적이고 능률적인 작업을 할 수 있는 효과가 제공된다.Loosen the fixing bolts 14 and 14 'of both hinges and pull the lever 12 downward to the right, the pivoting angle is tilted to the right about the hinge 13 to open the other side of the bobbin shaft to bobbin on the bobbin shaft 2 The bobbin 1 is fixed by tightening the adjusting nut 4, and the bobbin 1 is fixed and the pivot 19 is raised to be assembled and supported with the other side of the bobbin shaft 2, and the lever 12 is raised to lock the hinge 13 ′. When the front roller 17 is pushed to the wall surface of the pivot 19, it is fixed by tightening fixing bolts 14 and 14 'of both hinges 13 and 13'. At this time, the coil springs 9 and the leaf springs 10 of both supports alleviate the shock when the bobbin 1 is installed and prevent the loosening of both bushes 7 and 7 'when the bobbin shaft 2 is rotated. . Therefore, the present invention, unlike the conventional one, because the bobbin shaft (2) is supported on both sides, the static equilibrium about rotation does not appear uneven, it is uniform in the rotational speed and can be precisely processed and by using a bobbin suitable for the workload The effect is to make the work efficient and efficient.
