Description

디버링커터Deburring Cutter

본 고안은 디버링 커터에 관한 것으로, 특히 기어가공에 있어서 후처리로서 치형의 모서리 부분에 발생되는 버(burr)의 제거를 효율적으로 하기 위한 디버링 커터의 개선에 관한 것이다.The present invention relates to a deburring cutter, and more particularly, to an improvement of a deburring cutter for efficiently removing burrs generated at edge portions of teeth as a post-treatment in gear processing.

일반적으로, 기어가공에 있어서 세이퍼 또는 호빙가공에 의해 기어 치형부를 적삭가공하고, 모서리부분에 형성되는 버를 제거한 다음 세이빙가공한다. 이러한 기어가공에 있어서, 버를 제거하기 위하여 도 1에 도시된 바와같은 디버링커터(deburring cutter)를 사용하게 되며 디버링 커터(1)는 피가공 기어(2)의 양측 모서리 위에 배치되어 누르면서 피가공기어(2) 모서리부분의 버 및 날카로운 부분을 탈락시키는 것으로 디버링 커터(1)가 피가공기어(2) 위에 배치되어 함께 회전되도록 표면이 피가공기어(2)의 치형과 동일한 형상을 갖도록 가공되어야 함으로 디버링커터 가공에 따른 기어가공 작업효율의 저하가 초래되는 문제가 있었다.In general, in gear processing, gear teeth are roughly machined by a scraper or hobbing process, and burrs formed at corners are removed and then shaved. In this gear processing, a deburring cutter as shown in FIG. 1 is used to remove the burr, and the deburring cutter 1 is disposed on both edges of the gear 2 to be pressed while being pressed. (2) The burrs and sharp edges of the corners are dropped, so that the surface of the deburring cutter 1 is to be disposed on the gear 2 and rotated together so that the surface has the same shape as the teeth of the gear 2 to be rotated. There was a problem that the deterioration of the gear working efficiency caused by the deburring cutter processing.

본 고안은 상술한 종래 디버링커터에 따른 문제를 해소하도록 안출된 것으로, 피가공기어의 치형과 같은 형상으로 표면을 기어가공하지 않고 피가공기어의 측면에 배치되어 버를 간편하게 제거하도록 개선된 디버링커터의 제공을 목적으로 한다.The present invention is devised to solve the problem according to the conventional deburring cutter described above, the deburring cutter is improved to easily remove the burr is disposed on the side of the gear to be processed without gear surface in the same shape as the teeth of the gear to be processed For the purpose of providing

상기한 목적을 달성하기 위한 본 고안의 디버링 커터는 피가공기어의 양측면 각각에 접촉하도록 이격 배치되는 2개의 원판부재를 포함하며 상기 원판부재 각각은 피가공기어의 측면과 부분적으로 중첩되어 피가공물이 회전될 때 상기 원판부재의 모서리에 의해 피가공기어의 버를 탈락시키도록 구성된다.The deburring cutter of the present invention for achieving the above object includes two disk members spaced apart to contact each of both side surfaces of the gear to be processed and each of the disk members is partially overlapped with the side of the gear to be processed. It is configured to drop the bur of the gear to be processed by the edge of the disc member when rotated.

이하, 본 고안의 실시예를 도시한 첨부 도면을 참고하여 본 고안을 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in detail the present invention.

도 2는 본 고안에 따른 디버링커터(10)로 피가공기어(11) 모서리에서 날카롭게 형성된 버(12)를 제거하는 것을 보여주고 있다. 기어, 특히 헬리컬기어나 스퍼(spur)기어 가공시에 세이퍼 또는 호빙기로 치형가공하면 피가공기어(11)의 양측면의 모서리가 날카롭게 되며 버가 발생되는데 이를 제거하지 않게 되면 다른 기어와 맞물리게 될 때 원활하지 못하게 되는 문제가 발생되므로 고정밀의 기어를 얻을 수 없고 마모가 빠르게 되어 손상되는 문제가 있다. 이와같이 피가공기어(11)의 양측 모서리에서 버(12)를 제거하기 위하여 본 고안에 따른 디버링커터(10)는 소정 두께만큼 이격된 2개의 원판부재(13,14)가 축(15)으로 연결되어 있다. 통상의 선반에서 척에 피가공기어(11)를 물려놓고 원판부재(13)의 모서리가 피가공기어(11)의 양측면에 접촉되게 클램핑시켜놓고 피가공기어(11)를 회전시키면 피가공물(11)의 치형가공시 모서리에 형성된 버(12)가 원판부재(13,14)의 모서리에 의해 탈락된다. 원판부재(14)는 피가공기어(11)위에서 맞물려 회전되면서 지지된다. 이때 도 3에 도시된 바와같이 버(12)가 탈락될 때 극히 일부분의 버(13)가 새로이 치형부분쪽으로 형성될 수도 있으나 이러한 것은 피가공기어(11)의 후공정인 세이빙가공에서 모두 제거되므로 문제가 되지 않는다. 이와같이 표면에 피가공기어와 같은 치형을 원판부재(13)에 형성하지 않고도 피가공기어의 버가 형성된 모서리부분에 접촉배치된 원판부재(13)에 의해 버가 탈락되므로 간편하게 디버링가공을 수행할 수 있어 고정도의 기어를 얻을 수 있다.Figure 2 shows that the deburring cutter 10 according to the present invention to remove the burr 12 is formed sharply at the edge of the gear to be processed (11). When gears, especially helical gears or spur gears, are toothed with a shaper or hobbing machine, the edges of both sides of the gear 11 are sharpened and burrs are generated. If they are not removed, they are engaged with other gears. There is a problem that can not be obtained because the high accuracy of the gears can not be obtained and wear is quickly damaged. As described above, the deburring cutter 10 according to the present invention has two disc members 13 and 14 spaced apart by a predetermined thickness in order to remove the burrs 12 from both edges of the gear 11 to be connected to the shaft 15. It is. In a conventional lathe, the work gear 11 is held by the chuck and the edge of the disc member 13 is clamped to contact both sides of the work gear 11, and the work gear 11 is rotated. The burr 12 formed at the corners of the tooth is removed by the corners of the disc members 13 and 14. The disc member 14 is supported while being rotated in engagement on the gear to be processed (11). At this time, when the burr 12 is dropped as shown in FIG. 3, a very small part of the burr 13 may be newly formed toward the toothed part, but these are all removed from the shaving process, which is a post-process of the gear 11 to be processed. It doesn't matter. In this way, the burrs are dropped by the disc member 13 placed in contact with the edge of the burr of the gear to be formed without forming a tooth such as a gear on the surface of the disc member 13 so that deburring can be easily performed. There is a high accuracy gear.

본 고안에 따라, 기어가공시 피가공기어의 모서리에 형성되는 버를 제거하도록 원판부재를 피가공기어의 측면에 모서리부분이 접촉되게 배치시켜 피가공기어를회전시킴에 따라 간편하게 버를 제거할 수 있으며, 원판부재의 표면에 기어부를 형성하지 않음에 따라 디버링커터의 제작을 매우 간편하게 할 수 있어 기어가공시 디버링 가공을 매우 효율적이고 경제적으로 수행하는 효과가 있다.According to the present invention, it is possible to easily remove the burrs by rotating the gears by arranging the disc member in contact with the side of the gears so as to remove the burrs formed at the corners of the gears when machining the gears. In addition, since the gear part is not formed on the surface of the disc member, the deburring cutter can be manufactured very easily, and thus the deburring process can be performed very efficiently and economically.
