Description
본 발명은 팝 너트에 관한 것으로, 보다 상세하게는 가해지는 외력에 대한 내구성을 강화하도록 용접부위를 갖춘 이중 고정력 형성 타입 팝 너트에 관한 것이다. The present invention relates to a pop nut, and more particularly, to a double holding force forming type pop nut having a welded portion to enhance durability against an external force applied thereto.
일반적으로 차체 조립 또는 이와 관련되는 차체 브래킷 조립과정에서는 태핑(Tapping)가공이 되지 않은 패널간이나 글래스와 패널등 자동차에 구성되는 판형의 소재등에 볼트등을 체결할 때에는 이를 위한 체결수단으로 즉, 패널의 가공에 영향을 주지 않으면서 볼트 체결을 유도하는 팝너트(Pop Nut)가 이용되어진다.In general, when assembling a bolt or the like between panels that are not tapped in a vehicle body assembly or a vehicle bracket assembly related thereto or a plate-shaped material such as glass and a panel, the panel is used as a fastening means for this purpose. A pop nut is used to induce bolting without affecting the machining of the tool.
이와 같은, 팝 너트는 주로 볼트 사이즈가 M6이하인 적은 사이즈의 볼트를 체결할 때 사용되며, M6 이상인 경우에는 체결강도가 떨어져 사용하지 않음은 물론이다.As such, the pop nut is mainly used when tightening a bolt of a smaller size of M6 or less, and of course, when M6 or more, the fastening strength is not used.
이러한 팝 너트의 체결은 볼트 체결 전 단계에서 패널에 팝 너트를 먼저 장착한 뒤 볼트를 체결하게 되면, 상기 팝 너트가 변형되면서 패널에 밀착되어 패널 사이를 물고 있는 상태를 유지해 체결 강성을 유지하게 된다.When the pop nut is fastened, the pop nut is first mounted on the panel in the step before the bolt is fastened, and then the bolt is fastened to maintain the fastening rigidity by maintaining the state that the pop nut is deformed and closely held between the panels. .
그러나, 이와 같은 팝너트는 그 고정력인 체결 강성이 변형에 따른 패널 사이를 물고 있는 상태를 통해 얻어지는데 이는, 팝 너트 체결 부위로 가해지는 반복적이고 지속적인 진동 외력(수직·수평방향 외력과 전단력이 반복적으로 가해짐)을 이겨내기가 매우 취약해 초기 형상을 유지하지 못하고 변형되는 현상이 있게 된다.However, this pop nut is obtained through the clamping stiffness, which is the clamping force, between the panels due to the deformation, which means that the repetitive and continuous vibration external force (vertical and horizontal external force and shear force applied to the pop nut fastening site) is repeated. It is very fragile to overcome, so that it is not able to maintain the initial shape and deforms.
특히, 패널 사이를 물고 있도록 변형되는 부위로 외력이 집중되지만 상기 팝 너트의 특성상 패널과의 밀착력을 충분히 유지해야 만 하는데 이는, 상기 팝 너트의 체결 강성을 유지하기 위한 형상이나 구조 변형을 크게 제약하는 원인으로 작용하게 됨은 물론이다. In particular, the external force is concentrated to the portion that is deformed so as to be sandwiched between the panels, but due to the nature of the pop nut, the adhesive force with the panel must be sufficiently maintained, which greatly restricts the shape or structural deformation to maintain the fastening rigidity of the pop nut. Of course, it acts as a cause.
이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 체결되는 패널에 밀착되도록 변형되는 부위에 용접부위를 형성시켜 변형에 의한 패널과의 밀착력과 더불어 용접에 의한 고정력을 이중으로 형성함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-mentioned point, and by forming a welding part on a part to be deformed to be in close contact with the panel to be fastened, the purpose of forming a double fixing force as well as the adhesive force with the panel by deformation is formed. There is this.
상기와 같은 목적을 달성하기 위한 본 발명은, 팝너트가 대상 패널에 형성된 구멍에 삽입된 후 걸려지도록 상부측에 형성된 플랜지와;The present invention for achieving the above object, and the flange is formed on the upper side to be caught after being inserted into the hole formed in the target panel popnut;
내부로 형성된 관통홀로 삽입된 체결부재의 체결 회전력에 의해 변형되어 패널과의 밀착에 의한 고정력을 발생하도록 상기 플랜지에 비해 상대적으로 작은 직경을 갖고 일체로 형성된 슬리브와, 이 슬리브에 일체로 형성되면서 내부의 관통홀에 형성된 나사를 매개로 체결부재가 나사 체결되는 나사부로 이루어진 바디 및; A sleeve integrally formed with a relatively small diameter compared to the flange so as to be deformed by the fastening rotational force of the fastening member inserted into the through hole formed therein and to generate a fixing force by close contact with the panel, and integrally formed in the sleeve A body consisting of a screw portion in which a fastening member is screwed through a screw formed in the through hole of the screw;
상기 바디가 형성되지 않은 플랜지의 저면부 공간상에 구비되어 패널에 용접되면서 고정력을 발생시키는 용접돌기로 이루어진 것을 특징으로 한다. The body is formed on the bottom space of the flange of the flange is not formed, characterized in that consisting of a welding projection for generating a fixed force while being welded to the panel.
이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1(가)와 (나)는 본 발명에 따른 용접부위를 갖춘 팝 너트의 단면도를 도시한 것인바, 본 발명의 팝 너트는 대상 패널(P)에 형성된 구멍에 삽입된 후 걸려지도록 상부측에 형성된 플랜지(1)와, 이 플랜지(1)에 비해 상대적으로 작은 직경을 이루어 대상 패널(P)에 형성된 구멍에 삽입된 후 내부를 관통하는 관통홀(3)에 형성된 나사(5)에 체결되는 체결부재(A)에 의한 회전력에 의해 변형되어 패널(P)에 밀착되는 바디 및 상기 바디가 형성되지 않은 플랜지(1)의 저면부 공간상에 구비되어 패널(P)에 용접되는 용접돌기(6)로 이루어진다.Figure 1 (a) and (b) is a cross-sectional view of the pop nut with a welded portion according to the present invention, the pop nut of the present invention is inserted into the hole formed in the target panel (P) and the upper side to be hooked Fastened to the flange (1) formed in the screw (5) formed in the through hole (3) inserted into the hole formed in the target panel (P) to form a relatively small diameter compared to the flange (1) and penetrating the inside Deformed by the rotational force by the fastening member (A) to be in close contact with the panel (P) and the welding projection is provided on the space of the bottom portion of the flange (1) where the body is not formed is welded to the panel (P) 6) consists of.
그리고, 상기 바디는 내부로 형성된 관통홀(3)로 삽입된 체결부재(A)의 체결 회전력에 의해 변형되도록 비교적 얇은 두께로 이루어져 패널(P)에 밀착되어 고정력을 발생하는 슬리브(2)와, 이 슬리브(2)에 일체로 형성되면서 내부의 관통홀(3)에 형성된 나사(5)를 매개로 체결부재(A)가 나사 체결되는 나사부(4)로 이루어지게 된다.And, the body is made of a relatively thin thickness to be deformed by the fastening rotational force of the fastening member (A) inserted into the through hole (3) formed therein and the sleeve (2) in close contact with the panel (P) to generate a fixing force, It is integrally formed in the sleeve (2) is made of a screw portion (4) that the fastening member (A) is screwed through the screw (5) formed in the through hole (3) therein.
또한, 상기 용접돌기(6)는 1개 이상으로 형성되지만 도 1(나)에 도시된 바와 같이 약 120°등 간격으로 3개로 형성되는 것이 바람직함은 물론이다. In addition, it is preferable that the welding protrusions 6 are formed in at least one, but are formed in three at intervals of about 120 ° as shown in FIG. 1 (b).
이하 본 발명의 작용을 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 팝너트를 대상 패널(P)에 형성된 구멍에 삽입 즉, 도 2에 도시된 바와 같이 상기 팝너트의 바디를 패널(P)의 구멍에 끼워 플랜지(1)가 패널(P)에 안착되도록 한 후, 볼트등의 체결부재(A)를 팝너트의 관통홀(3)로 삽입시켜 시계 방향이나 반 시계 방향으로 회전하여 준다.According to the present invention, the pop nut is inserted into the hole formed in the target panel P, that is, the flange 1 is seated in the panel P by inserting the body of the pop nut into the hole of the panel P as shown in FIG. After that, the fastening member A, such as a bolt, is inserted into the through hole 3 of the pop nut to rotate clockwise or counterclockwise.
이와 같이, 상기 체결부재(A)를 회전시켜 주게 되면 팝너트의 바디를 이루는 나사부(4)에 형성된 나사(5)와 나사 체결되면서, 상기 체결부재(A)를 회전에 따른 나사부(4)의 상승력으로 슬리브(2)부위가 상승력을 받으면서 변형되고, 이에 따라 상기 슬리브(2)의 변형에 의해 패널(P)의 저면부위로 밀착되어 팝너트는 플랜지(1)와 슬리브(2)사이에 낀 패널(P)과 고정력을 유지하게 된다. As such, when the fastening member A is rotated, the screw 5 is screwed into the screw 5 formed in the threaded portion 4 constituting the body of the pop nut, and the fastening member A of the threaded portion 4 is rotated. The sleeve 2 is deformed by the upward force, and thus the sleeve 2 is pressed against the bottom of the panel P by the deformation of the sleeve 2 so that the pop nut is caught between the flange 1 and the sleeve 2. The panel P and the fixing force are maintained.
이어, 상기 플랜지(1)의 저면 부위로 형성된 용접돌기(6)를 용접하게 되는데 즉, 도 2에 도시된 바와 같이 패널(P)사이를 밀착하고 있는 팝너트의 플랜지(1)저면에 형성된 용접돌기(6)부위에 용접건(G)을 위치시켜 용접하면, 상기 용접돌기(6)가 녹으면서 패널(P)에 밀착되는 용접고정부(K)를 형성하게 되어진다.Subsequently, the welding protrusion 6 formed by the bottom portion of the flange 1 is welded. That is, the welding formed on the bottom surface of the flange 1 of the pop nut that closely contacts the panel P as shown in FIG. 2. When the welding gun G is positioned and welded on the projection 6, the welding projection 6 is melted to form a welding fixing portion K that is in close contact with the panel P.
이와 같이, 상기 팝너트가 플랜지(1)와 슬리브(2)사이에 낀 패널(P)과의 밀착에 따른 고정력과 더불어 상기 용접돌기(6)를 매개로 플랜지(1)와 패널(P)간 용접에 의한 고정력을 추가로 발생시켜 주게 되면, 상기 팝너트의 체결부위로 가해지는 반복적이고 지속적인 진동 외력(Fx,Fy)에 대해서도 장기간 경과되더라도 초기 형상을 유지할 수 있는 충분한 내구성을 갖아 그 형상의 변형을 발생시키지 않게 된다. In this way, the pop-nut between the flange (1) and the panel (P) via the welding projection (6) with the fixing force according to the close contact with the panel (P) sandwiched between the flange (1) and the sleeve (2). When the fixing force is additionally generated by welding, the shape of the shape is deformed due to sufficient durability to maintain the initial shape even after a long period of time even for repeated and continuous external force (Fx, Fy) applied to the fastening portion of the pop nut. Will not generate
이상 설명한 바와 같이 본 발명에 의하면, 팝너트가 체결되는 패널과의 밀착에 따른 고정력과 더불어 페널과의 용접에 의한 용접 고정력을 이중으로 형성하게 되고, 이에 따라 팝너트의 체결부위로 가해지는 반복적이고 지속적인 수직·수평방향 외력 및 전단력에 대한 내구성이 한층 강화되어짐은 물론이다.As described above, according to the present invention, the fixing force according to the close contact with the panel to which the pop nut is fastened, and the welding fastening force by welding with the panel are formed in duplicate, and thus the repetitive force applied to the fastening part of the pop nut is repeated. Of course, the durability against continuous vertical and horizontal external force and shear force is further strengthened.
또한, 본 발명은 용접을 통해 팝너트의 고정력을 이중으로 강화시키므로 체결되는 패널과의 밀착력을 충분히 유지할 수 있는 팝 너트 형상에 대한 구조 변형등이 필요 없는 효과가 있음은 물론이다.In addition, since the present invention reinforces the fixing force of the pop nut double by welding, there is, of course, an effect that does not require structural modifications to the shape of the pop nut that can sufficiently maintain the adhesion with the panel to be fastened.
