일반적으로 자동차용 엔진이나 각종 산업용 엔진등에는 오일의 여과를 위한 오일필터가 분리가능케 결합되며, 가장 흔히 이용되는 오일필터는 카트리지의 중앙부에 나사공을 형성하여 어댑터를 이용하여 엔진이 갖는 하우징에 나사결합고정해 주도록 하고 있다.In general, an oil filter for filtration of oil is detachably coupled to an automobile engine or various industrial engines, and the most commonly used oil filter is a screw hole formed at the center of the cartridge to be screwed into a housing of the engine using an adapter. I'm going to fix it.

이러한 오일필터를 엔진에 나사결합고정하는데 이용되는 어댑터는 도 1에서와 같이 내부에는 오일순환을 위한 연통공이 형성되고 또 외면에는 죄임을 위한 육각의 죄임부를 사이에 두고 상하에 나선부가 형성되는 특수한 형태를 지니게 된다.The adapter used to screw the oil filter to the engine has a specially formed spiral hole at the top and bottom with a communication hole for oil circulation inside and a hexagonal clamp for clamping on the outside, as shown in FIG. Form.

이에 이제껏 이용되어 오고 있는 오일필터용 어댑터는 도 1에서와 같이 긴 육각봉체(200)를 소정길이로 컷팅하여 소재(300)를 얻고, 소재(300)에 드릴을 이용하여 연통공(420)을 천공하여 1차가공품(400)을 얻고, 1차가공품(400) 중앙부에 육각의 죄임부(520)를 남겨두고 상하를 절삭가공하여 상하원통부(540)(560)를 갖는 2차가공품(500)을 얻은 다음 2차가공품(500)의 상하원통부(540)(560) 외면을 나사가 공하여 내부에 연통공(620)이 형성되고 또 외면에는 육각의 죄임부(640)를 사이에 두고 상하에 나선부(660)(680)를 갖는 완성된 형태의 어댑터(600)를 얻도록 하고 있다.The oil filter adapter that has been used so far is to cut the long hexagon bar 200 to a predetermined length as shown in Figure 1 to obtain the material 300, using a drill in the material 300 to the communication hole 420 Punched to obtain the primary processed product 400, the secondary processed product 500 having the upper and lower cylindrical portions 540, 560 by cutting the upper and lower, leaving a hexagonal clamping portion 520 in the center of the primary processed product 400 After obtaining the upper and lower cylindrical parts 540, 560 of the secondary processed product 500, the communication hole 620 is formed inside the screw and the upper and lower sides of the hexagonal clamping part 640 between the outer surface.
