엔진 흡기매니폴드의 인젝터삽입공구조Injector Insertion Structure of Engine Intake Manifold

본 발명은 엔진 흡기매니폴드의 인젝터삽입공구조에 관한 것으로, 특히 요구되는 형상의 내측형상을 가진 고무관이 삽입공에 삽입되어, 이 고무관으로 인젝터가 삽입고정될 수 있게 됨으로써 흡기매니폴드에 삽입공을 직접 형성시 가공의 난해함이 해결될 수 있도록 된 엔진흡기매니폴드의 인젝터삽입공구조에 관한 것이다.The present invention relates to an injector insertion hole structure of an engine intake manifold. In particular, a rubber tube having an inner shape of a required shape is inserted into an insertion hole so that the injector can be inserted into and fixed to the rubber intake manifold. It relates to the injector insertion hole structure of the engine intake manifold, which can solve the difficulty of processing when directly formed.

일반적으로 자동차의 엔진에서 연료는 인젝터를 통해 연소실내로 분사되며, 이 인젝터는 엔진의 측부에 취부되는 흡기매니폴드를 통해 삽입되어 끝부분이 흡기포트의 내부에 위치하도록 되어 있다.In general, in the engine of a vehicle, fuel is injected into the combustion chamber through an injector, and the injector is inserted through an intake manifold mounted to the side of the engine so that the end is located inside the intake port.

따라서, 상기 인젝터를 삽입고정하기 위한 인젝터삽입공이 흡기매니폴드에 형성되어지는데, 종래의 인젝터삽입공은 도 1에 도시된 바와 같이, 흡기매니폴드(1)의 엔진측 부분의 상단부(1a)에 경사지게 원형의 구멍 즉, 삽입공(2)이 형성되되, 이 삽입공(2)의 내부에는 인젝터가 걸려질 수 있는 걸림턱(2a)이 형성되어 있다.Therefore, an injector insertion hole for inserting and fixing the injector is formed in the intake manifold, and the conventional injector insertion hole is formed in the upper end portion 1a of the engine side portion of the intake manifold 1 as shown in FIG. A circular hole is formed obliquely, that is, the insertion hole (2) is formed, the engaging jaw (2a) is formed in the interior of the insertion hole (2) can be caught.

따라서, 상기 삽입공(2)으로 인젝터가 삽입고정되어 인젝터의 노즐부분이 흡기포트쪽에 위치하게 됨으로써 연료가 연소실내로 분사될 수 있게 된다.Accordingly, the injector is inserted into the insertion hole 2 so that the nozzle portion of the injector is positioned on the intake port side, so that fuel can be injected into the combustion chamber.

한편, 상기 삽입공(2)은 회전절삭가공에 의해 성형되는데, 상기 흡기매니폴드(1)의 형상적 특징에 의해 즉, 돌출부(1b)와 상부로 굽어진 흡입구(1c)의 간섭으로 인해 공구가 삽입공(2)의 위쪽에서는 접근될 수 없으므로, 흡기포트와 연결되는 아래쪽 개구부를 통해 위쪽으로 진행되면서 가공을 실시해야만 하고, 또한 걸림턱(2a)을 성형해야만 하는 관계로 1차 가공에서 삽입공(2)의 형상성형이 완료되지 않고 1차적으로는 리이밍가공을 한 후, 2차적으로 백페이싱가공을 실시해야만 하는 번거로움이 있어, 작업이 난해하고 작업효율이 떨어지게 되는 문제점이 있었다.On the other hand, the insertion hole (2) is formed by a rotary cutting process, due to the shape of the intake manifold (1), that is, the tool due to the interference of the projection (1b) and the inlet 1c bent upwards Is not accessible from the upper side of the insertion hole 2, the process must be carried out while proceeding upward through the lower opening connected to the intake port, and also inserted in the primary processing since the locking jaw 2a must be formed. There was a problem in that the shape of the ball 2 was not completed and the reaming process was performed first, and then, the backfacing process had to be performed secondarily, and the work was difficult and the work efficiency was reduced.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 흡기매니폴드의 선단부에는 1차가공만으로 가공이 완료되는 단순구멍을 형성하고, 이 구멍에 인젝터고정에 요구되는 걸림턱을 갖춘 고무관을 삽입하여, 이 고무관에 인젝터를 삽입고정할 수 있게 됨으로써 삽입공형성의 난해함을 해결할 수 있도록 된 엔진 흡기매니폴드의 인젝터삽입공구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the above problems, the front end of the intake manifold is formed a simple hole to complete the processing only by the primary processing, this hole has a rubber tube with a locking step required for fixing the injector It is an object of the present invention to provide an injector insertion hole structure of an engine intake manifold which can be inserted into and fixed to the rubber tube to solve the difficulty of insertion hole formation.

상기와 같은 목적을 달성하기 위한 본 발명은, 흡기매니폴드의 선단부에 1차 가공만으로 성형완료되는 단순한 삽입공을 성형하고, 이 삽입공에 고무관을 삽입하는 구조로 이루어지되, 이 고무관의 내부에는 인젝터 고정을 위한 걸림턱이 형성되어 있고, 고무관 자체의 상기 삽입공내 고정을 위한 스톱퍼가 구비되어 있다.The present invention for achieving the above object is made of a structure for molding a simple insertion hole that is completed by primary processing only at the front end of the intake manifold, and inserting a rubber tube into the insertion hole, the inside of the rubber tube A locking jaw for fixing the injector is formed, and a stopper for fixing in the insertion hole of the rubber tube itself is provided.

즉, 흡기매니폴드에는 단순한 구멍을 형성하고, 이 구멍에 삽입고정된 고무관에 인젝터를 삽입고정하게 됨으로서 공구의 간섭을 피하기 위해 2차로 진행되던 흡기매니폴드에의 삽입공형작업이 매우 간단해짐으로써 작업의 효율성을 증대시킬 수 있게 된다.In other words, by forming a simple hole in the intake manifold and inserting and fixing the injector in the rubber tube inserted and fixed in the hole, the operation of inserting into the intake manifold, which has been performed secondarily to avoid tool interference, becomes very simple. It can increase the efficiency of.

이하 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 인젝터삽입공구조가 적용된 삽입공형성 부분의 분리단면도로서, 본 발명은 흡기매니폴드(1)의 흡기포트측 선단부의 상단부(1a)에 상기 흡기포트쪽으로 경사진 삽입공(2)이 형성되되, 이 삽입공(2)은 1차 가공만으로 단순한 구멍으로서 형성되고, 이 삽입공(2)에 인젝터를 수용할 수 있는 고무관(3)이 삽입고정되는 구조로 되어 있다.FIG. 2 is an exploded cross-sectional view of the insertion hole forming portion to which the injector insertion hole structure according to the present invention is applied. 2) is formed, and this insertion hole 2 is formed as a simple hole only by primary processing, and the rubber tube 3 which can accommodate an injector is inserted into this insertion hole 2, and is structured.

여기서, 상기 고무관(3)은 종래 인젝터삽입공의 지름과 같은 내경을 가지며, 즉 인젝터의 직경과 같은 내경을 가지며, 중간부분에 인젝터의 하방진행을 막아 인젝터가 고정될 수 있도록 된 걸림턱(3a)가 형성되어 있으며, 상단부의 외주면에 외경으로 부터 다소 확장된 플랜지(3b)가 형성되고, 하부에는 링(ring)형상으로 되어 고무관(3)의 몸체속에 삽입고정된 2개의 스톱퍼(3c)가 구비되어 있다.Here, the rubber tube 3 has an inner diameter equal to the diameter of a conventional injector insertion hole, that is, has an inner diameter equal to the diameter of the injector, and a locking step 3a to prevent the injector from moving downward in the middle part thereof so that the injector can be fixed. ) Is formed, a flange (3b) extending slightly from the outer diameter is formed on the outer circumferential surface of the upper end, and two stoppers (3c) fixed in the body of the rubber tube (3) in a ring shape at the bottom It is provided.

따라서, 상기 고무관(3)이 흡기매니폴드(1)의 상단부(1a)에 형성된 삽입공(2)속에 삽입될 때 상기 플랜지(3b)가 그 체결강도를 높여주며, 상기 스톱퍼(3c)는 삽입공(3)의 내측면에 강하게 끼워지게 되어 고무관(3)이 삽입공(2)의 내측 측 흡기매니폴드(1)의 안쪽으로 밀려드는 것을 방지하게 된다.Therefore, when the rubber tube 3 is inserted into the insertion hole 2 formed in the upper end 1a of the intake manifold 1, the flange 3b increases its fastening strength, and the stopper 3c is inserted. The inner side of the ball 3 is strongly fitted to prevent the rubber tube 3 from being pushed into the intake manifold 1 on the inner side of the insertion hole 2.

또한, 고무관(3)과 삽입공(2) 사이로 가스가 새는 것을 막기 위하여 삽입공(2)의 내주면과 접촉되는 고무관(3)의 수직면(3d)에는 실링제가 도포되게 된다.In addition, a sealing agent is applied to the vertical surface 3d of the rubber tube 3 in contact with the inner circumferential surface of the insertion hole 2 to prevent gas leakage between the rubber tube 3 and the insertion hole 2.

따라서, 상기 고무관(3)을 삽입공(2) 속에 압입하고, 이 고무관(3)에 인젝터를 삽입고정할 수 있게 되므로, 인젝터삽입공의 형성을 위해서 상기 삽입공(2)의 형성시 1차 리이밍가공과 2차 백페이싱가공을 실시해야할 필요가 없이 삽입공(2)을 단순히 1차 가공에 의해 뚫기만 하면 되므로 기계적 절삭가공의 난해함이 해결되에 되었다.Therefore, since the rubber tube 3 can be press-fitted into the insertion hole 2 and the injector can be inserted and fixed in the rubber tube 3, the first time when the insertion hole 2 is formed to form the injector insertion hole. It is not necessary to perform the reaming process and the secondary backfacing processing, and the difficulty of mechanical cutting is solved by simply drilling the insertion hole 2 by the primary processing.

이상 설명한 바와 같이 본 발명에 의하면, 인젝터삽입을 위해 요구되는 형상을 내부에 갖춘 고무관을 단순한 구멍으로 형성된 삽입공에 끼우고, 상기 고무관에 인젝터를 삽입고정하게 됨으로써 인젝터삽입을 위해 요구되는 형상을 가진 삽입공을 흡기매니폴드에 직접 형성할 시 유발되는 절삭가공의 난해함을 해결할 수 있게 되었고, 가공 및 조립의 용이성으로 인해 작업시간이 단축되게 되는 효과가 있다.As described above, according to the present invention, a rubber tube having a shape required for inserting an injector is inserted into an insertion hole formed by a simple hole, and the inserting and inserting of the injector into the rubber tube has a shape required for inserting the injector. It is possible to solve the difficulty of cutting processing caused when the insertion hole is formed directly on the intake manifold, and the work time is shortened due to the ease of processing and assembly.
