이하 첨부된 도면을 참조하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 클램핑전의 가체결상의 정면도, 측면도(A)이다.2 is a front view and a side view (A) of a preformed image before clamping according to the present invention.
도시된 바와 같이, 금속 판재로 성형된 밴드형상의 클램프(100)가 도시되어있다. 접속면에서 상판(80)과 하판(90)으로 구별되고, 상기 상판(80)은 복수의 엠보싱 형상의 돌기(10)와, 경사면(20)과 홈(21) 및 일면 가장자리에는 걸림턱(22)으로 이루어진 걸림홀(23)와, 좌향이면서 삼각뿔형상의 제1 걸림돌기로 구성된 제1 결합부(30)를 포함하는 체결구조를 구성한다.As shown, a band-shaped clamp 100 molded from a metal sheet is shown. In the connection surface, the upper plate 80 and the lower plate 90 are distinguished, and the upper plate 80 includes a plurality of embossed protrusions 10, a slope 20, a groove 21, and a locking jaw 22 at one edge thereof. ) And a fastening structure including a locking hole 23 formed of the first coupling part and a first coupling part 30 formed of a first locking protrusion having a triangular pyramid shape.
역시, 하판(90)의 단부에는 엠보싱 형상의 삽입돌기(10)에 삽입되는 꼬리모양의 삽입 체결부(70)와, 원형을 이루면서 일측 반원에는 돌기형성이고 타측 반원에는 오목한 형상을 이룬 제1 돌기체결부(40)와, 제2 돌기체결부(30)의 돌기방향이 반대인 두 개의 제2 및 제3 돌기체결부(50,60)를 포함하는 체결구조를 구성한다.Also, at the end of the lower plate 90, a tail-shaped insertion fastening portion 70 inserted into the embossed insertion protrusion 10 and a first protrusion having a circular shape and forming a protrusion on one side semicircle and a concave shape on the other semicircle. A fastening structure includes a fastening part 40 and two second and third protrusion fastening parts 50 and 60 having opposite projection directions of the second protrusion fastening part 30.
상기 클램프(100)의 가체결 상태에서, 체결되는 부위는 걸림턱(23)와 제1 돌기체결부(40)와, 제2 돌기체결부(30)와 제3 돌기체결부(50)가 각각 체결되는 부위가 된다.In the pre-tightening state of the clamp 100, the fastening portions of the clamping jaw 23, the first protrusion fastening portion 40, the second protrusion fastening portion 30, and the third protrusion fastening portion 50 are respectively. It becomes a part to be fastened.
따라서, 상기과 같은 클램프(100)의 가체결 상태의 체결부위는 조립전 클램프(100)의 초기 걸림 상태를 유지하여 작업성에 도움을 준다.Therefore, the fastening part in the pre-tightening state of the clamp 100 as described above helps maintain workability of the initial clamping state of the clamp 100 before assembly.
도 3은 본 발명에 따른 클램프의 완전 체결 후의 정면도 및 측면도(B)를 도시하고 있다.Figure 3 shows a front view and a side view (B) after full clamping of the clamp according to the invention.
도시된 바와 같이, 측면도(B)에서 완전 체결시 체결되는 부위는 하판(90)의 꼬리부분의 삽입체결부(70)가 완전히 엠보싱 형상의 돌기(10)에 끼워지면서 삽입되게 된다. 또한 상기 구조에서 체결되는 부위는 역시 걸림홀(23)과 제2 돌기(50)와, 제1 돌기(30)와 제2 돌기(60)이다.As shown, the portion that is fastened when fully fastened in the side view (B) is inserted while the insertion fastening portion 70 of the tail portion of the lower plate 90 is completely inserted into the embossed projection 10. In addition, the portion fastened in the structure is also a locking hole 23 and the second projection 50, the first projection 30 and the second projection (60).
도 4는 본 발명에 따른 클램프의 사시도이다.4 is a perspective view of a clamp according to the present invention.
상기 전체 클램프(100)는 밴드형의 형상을 가지면서 양단부에는 복수개의 체결구조를 구비한다. 체결 수단은 엠보싱 형태의 돌기들(10)와 꼬리형태의 삽입 체결부(70)가 상호 물리면서 결합하고, 나머지 체결 수단은 홈(21) 및 오목(20,41)과 볼록(30,40,50,60)으로 이루어진 걸림 수단으로 체결을 완성한다.The entire clamp 100 has a band-like shape and has a plurality of fastening structures at both ends. The fastening means is the embossed protrusions 10 and the tail-shaped insertion fastening portion 70 is engaged with each other, the other fastening means is the groove 21 and the concave (20, 41) and the convex (30, 40, 50, 60) to complete the fastening by the locking means.
상기와 같은 클램프의 특징은 엠보싱 형태의 가이드 형상을 가지되, 부트의 고속 회전이나 온도 변화에 따른 열 변형에 의한 클램프 귀 벌어짐을 방지하기 위한 구조를 가진다. 또한 부트와 접하는 클림프내면이 연속적으로 이루어져 있어 그리스 릭(grease leak) 방지에 용이하고, 조립전 클램프의 초기 걸림 상태를 유지하여 작업성도 용이한 장점이 있다. 즉, 조립시 야기되는 비틀어짐은 엠보싱 가이드 구조에 의해 해결되며, 부트의 수축 반력 및 온도 변화에 다른 클램프 귀 벌어짐은 완전 체결 후 걸림 구조에 의한 체결 방식에 의해 해결된다. 특히, 걸림 체결에 의한 구조는 강도 보강에 유리한 장점이 있다.Features of the clamp as described above has a guide shape of the embossed form, has a structure for preventing the clamp ear opening due to thermal deformation due to high-speed rotation of the boot or temperature changes. In addition, since the inner surface of the crimp in contact with the boot is made continuously, it is easy to prevent grease leak and maintains the initial catch state of the clamp before assembling. That is, the twist caused during assembly is solved by the embossing guide structure, and the clamp ear gap which is different from the contraction reaction force and the temperature change of the boot is solved by the fastening method by the locking structure after full fastening. In particular, the structure by the engaging fastening has an advantage in strength reinforcement.
따라서, 본 발명에 따른 자동차용 구동축의 조인트 클램프는 엠보싱 형성과 걸림 체결로 미끄러짐을 방지하고, 조립 공정상 불량 발생의 원인을 제거하는 한편, 귀없는 구조로서 유효 외경의 축소 및 균일한 조임력을 유지하는 장점이 있다.Therefore, the joint clamp of the drive shaft for automobiles according to the present invention prevents slipping by embossing formation and engaging fastening, eliminates the cause of defects in the assembling process, and reduces the effective outer diameter and maintains a uniform tightening force as an earless structure. There is an advantage.
