Description

연료 휠러 넥 어셈블리 구조{Fuel filler neck assembly structure}Fuel filler neck assembly structure

본 발명은 연료 휠러 넥(Filler Neck)어셈블리 구조에 관한 것으로서, 더욱 상세하게는 종래의 휠러 튜브, 리테이너 및 캡 홀더를 각각 사출하고 압입 및 진동융착 등의 공정에 있어서, 휠러 튜브와 캡 홀더를 일체형으로 사출하고 리테이너의 형상을 변경함으로써, 공정을 단순화시키는 동시에 원가를 절감하고, 또한 진동 융착 공정을 생략함으로써, 부품 성형시 가해지는 하중을 방지하는 효과가 있는 연료 휠러 넥 어셈블리 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel wheeler neck assembly structure, and more particularly, to a conventional wheeler tube, a retainer, and a cap holder, respectively, and integrating the wheeler tube and the cap holder in a process such as press fitting and vibration welding. The present invention relates to a fuel wheeler neck assembly structure which has the effect of preventing the load applied during part molding by simplifying the process by reducing the shape of the mold and changing the shape of the retainer, and reducing the cost, and also eliminating the vibration welding process.

일반적으로 자동차의 연료 휠러 넥 어셈블리의 성형 방법을 보면, 도 1에 도시한 바와 같이, 먼저 휠러 튜브(30), 리테이너(20) 및 캡 홀더(10)를 각각 사출하고, 사출된 휠러 튜브(30)에 리테이너(20)를 압입한다.In general, the molding method of the fuel wheeler neck assembly of an automobile, as shown in FIG. 1, first injects the wheeler tube 30, the retainer 20 and the cap holder 10, and then injects the wheeler tube 30. ), The retainer 20 is press-fitted.

이때 상기 리테이너(20)는 억지끼움으로 압입되어 상기 휠러 튜브(30)의 걸림턱(15)에 걸려 고정되게 된다.At this time, the retainer 20 is press-fitted into an interference fit and is caught and fixed to the locking jaw 15 of the wheeler tube 30.

그 다음에 상기 캡 홀더(10)를 상기 휠러 튜브(30)의 상단에 맞춤 끼움으로 고정시킨다.The cap holder 10 is then secured to the top of the wheeler tube 30 by fit fitting.

여기서 미설명부호 11은 플레이트를 나타내는 것으로 차체와 고정시켜 전체 어셈블리의 안정화를 도모한다.Here, reference numeral 11 denotes a plate, which is fixed to the vehicle body to stabilize the entire assembly.

도 2에 도시한 바와 같이 상기 캡 홀더(10)를 리테이너(20)가 압입되어 있는 휠러 튜브(30)의 상부에 위치시키고 진동 융착으로 융착한다.As shown in FIG. 2, the cap holder 10 is positioned on the top of the wheeler tube 30 into which the retainer 20 is press-fitted and fused by vibration welding.

이때, 캡 홀더(10)의 하부에 상기 리테이너(20)의 상부가 걸려 고정된다.At this time, the upper portion of the retainer 20 is fixed to the lower portion of the cap holder 10.

그러나, 상기와 같은 공정으로 어셈블리를 제작하였을 때에는 각각의 조립체, 예를들어 휠러 튜브, 리테이너 및 캡 홀더를 각각 사출함으로써, 제조공정이 복잡해지고 원가가 상승하는 문제점이 있었다.However, when the assembly is manufactured in the above-described process, by injecting each assembly, for example, the wheeler tube, the retainer and the cap holder, respectively, there is a problem that the manufacturing process is complicated and the cost increases.

또한, 제품 성형시 진동 융착을 하게 되면 휠러 튜브에 대하여 막대한 하중(대략 450(kgf)이 발생하여 이것이 제품내에 잔류응력으로 작용하게 되어, 주행중 진동에 의한 지속적인 하중이 휠러 튜브에 가해질 경우 제품내 남아있던 잔류응력 부위에 균열이 발생할 위험이 있어 가급적이면 진동 융착은 수행하지 않는 것이 바람직하게 된다.In addition, the vibration welding during product molding causes an enormous load (approximately 450 (kgf)) on the wheeler tube, which acts as a residual stress in the product, and remains in the product when a continuous load caused by vibration while driving is applied to the wheeler tube. Since there is a risk of cracking in the residual stress area, it is desirable to avoid vibration fusion as possible.

따라서, 본 발명은 종래의 휠러 튜브, 리테이너 및 캡 홀더를 각각 사출하고 압입 및 진동융착등의 공정에 있어서, 휠러 튜브와 캡 홀더를 일체형으로 사출하고 리테이너의 형상을 변경함으로써, 공정을 단순화시키는 동시에 원가를 절감하고, 또한 진동 융착 공정을 생략함으로써 부품성형시 가해지는 하중을 방지하는 목적을 달성하기 위하여 본원 출원인은 첨부한 도 3에 도시한 바와 같이 연료탱크로 연료를 주입하고 일측은 차체에 고정되는 휠러 튜브(30)와, 상기 휠러 튜브(30)에 끼움 삽입되어 연료의 주입을 가능하게 하는 동시에 연료의 역류를 막아주도록 V자형 홈(22)을 갖는 리테이너(20)와, 상기 리테이너(20)를 고정하기 위해 리테이너(20) 상부에 고정 설치되는 캡 홀더(10)로 구성된 연료 휠러 넥 어셈블리 구조에 있어서, 상기 휠러튜브(30)와 캡 홀더(10)를 일체로 사출 성형한 것을 특징으로 하는 연료 휠러 넥 어셈블리 구조를 이미 출원(출원번호:1999-53107)한 바 있다.Accordingly, the present invention simplifies the process by injecting the conventional wheeler tube, the retainer and the cap holder, and injecting the wheeler tube and the cap holder integrally and changing the shape of the retainer in processes such as press fitting and vibration welding, respectively. In order to reduce the cost and to achieve the purpose of preventing the load applied during the molding part by eliminating the vibration welding process, the applicant of the present invention injects fuel into the fuel tank and one side is fixed to the vehicle body as shown in FIG. A retainer 20 having a wheeler tube 30 to be inserted into the wheeler tube 30 and having a V-shaped groove 22 to prevent fuel from flowing back while allowing fuel injection, and the retainer 20. In the fuel wheeler neck assembly structure consisting of a cap holder 10 fixedly installed on an upper part of the retainer 20 for fixing the wheeler tube 30 and the cap. Already filed a fuel Wheeler neck assembly structure, it characterized in that the further injection molding 10 integrally (Application No. 1999-53107) is a bar.

그 결과, 휠러 튜브(30)와 캡 홀더(10)를 일체형으로 사출함으로써, 공정을 단순화시키면서 원가도 절감할 수 있고, 종래의 진동 융착에 의해 부품 성형시 가해지던 하중을 없애주어 부품의 손상을 줄일 수 있는 효과를 얻어내었다.As a result, by injecting the wheeler tube 30 and the cap holder 10 integrally, the cost can be reduced while simplifying the process, and the damage of the parts can be eliminated by eliminating the load applied during the molding of the parts by the conventional vibration welding. A reduction effect was obtained.

그러나, 제품의 성형 공정중에 진동 융착시, 휠러 튜브에 가해지는 하중(450kf)이 제품내에 잔류응력으로 작용하고, 주행중에 지속적인 하중이 휠러 튜브에 가해질 경우 제품내에 남아 있던 잔류응력 부분(융축으로 접합된 부분)에 크랙이 발생하고, 주행중에 도로면으로부터 튀어오르는 돌맹이등이 휠러튜브에 부딪히게 됨에 따라, 부딪힌 부분에 순간적인 하중이 작용되어 크랙을 발생시키는 문제점이 있다.However, during vibration fusion of the product, the load (450kf) applied to the wheeler tube acts as a residual stress in the product, and the residual stress portion remaining in the product (bonded by fusion) when the continuous load is applied to the wheeler tube while driving. Cracks are generated, and a boulder or the like bouncing from the road surface hits the wheeler tube while driving, there is a problem in that a moment is applied to the bumped portion to generate a crack.

따라서, 본 발명은 연료 휠러 넥 어셈블리 제품을 성형시에 잔류응력을 낮추는 동시에 돌맹이등이 튀어올라 순간적으로 줄 수 있는 충격을 효과적으로 흡수하여 제품의 크랙을 방지할 수 있도록 다수의 보강용 립이 일체로 사출 성형된 구조의 연료 휠러 넥 어셈블리 구조를 제공하는데 그 목적이 있다.Accordingly, the present invention is to reduce the residual stress at the time of molding the fuel wheeler neck assembly product, and at the same time a plurality of reinforcing ribs integrally to prevent the product crack by effectively absorbing the impact that can be instantaneously bouncing off the stone. The object is to provide an injection molded fuel wheeler neck assembly structure.
