본 고안은 인장스프링 고정구에 관한 것으로, 더욱 상세하게는 인장코일스프링의 한쪽단에 축방향의 길이조정이 가능한 볼트를 설치하여 렌치 등의 체결공구를 사용하여 스프링탄성을 임의로 조정가능하도록 한 인장코일스프링 고정구에 관한 것이다.The present invention relates to a tension spring fixture, and more particularly, a tension coil having an adjustable length in the axial direction at one end of the tension coil spring, and allowing a spring elasticity to be arbitrarily adjusted using a fastening tool such as a wrench. Relates to a spring fixture.
일반적으로 스프링에는 스프링 양단을 서로 대항하는 방향으로 압축력을 가하면 탄성을 가지게 되는 압축스프링과 서로 반대향하는 방향으로 인장력을 가하면 탄성을 가지게 되는 인장스프링, 스프링의 축방향에 대해 비틀림력을 추게되면 탄성을 가지게 되는 토션스프링등 받는힘의 방향과 스프링이 갖게 되는 탄성의 관계를 토대로 3가지로 분류된다.In general, a spring has a compression spring that has elasticity when compressing the opposite ends of the spring against each other, and a tension spring that has elasticity when the tensile force is applied in a direction opposite to each other, and elasticity when a torsional force is applied to the axial direction of the spring. It is classified into three types based on the relationship between the direction of the force applied and the elasticity of the spring.
상기한 스프링은 양단을 고정하거나 걸어서 사용하게 된다.The spring is used to fix or walk both ends.
따라서 압축스프링은 양단을 면취가공하거나 소형인 경우는 그대로 사용하고 있으며, 인장스프링은 양단의 일부 선재를 풀어서 고리형태로 형성한 다음 양단을 걸어서 사용하거나 첨부도면 제1도에 도시된 바와같이 고리의 변형을 방지하고 고리를 좀더 강성이 있게 만들기 위해 코일형태로 촘촘히 감겨진 스프링의 양단 일측에 고리(10)가 달리고 톱니(11)를 가진 평판나사(12)를 각각 강제압입 방식으로 나사결합하여 사용하는데 이와 같은 것은 사용중 고하중이나 반복피로 하중이 가해질 경우 몇개의 톱니(11)로 하중을 받치고 있는 구조이므로 장시간 사용에는 문제가 있어 피로파괴가 일어났다.Therefore, the compression spring is used when both ends are chamfered or small, and the tension spring is formed by unwinding some wire rods at both ends to form a ring, and then using both ends to hang them or as shown in FIG. In order to prevent deformation and to make the ring more rigid, the ring 10 runs on both ends of the coil wound tightly in the form of a coil, and the flat screw 12 having the teeth 11 is screwed together by a forced press method. However, this is a structure that is supported by a few teeth (11) when a heavy load or repeated fatigue load is applied during use, there is a problem in long-term use, fatigue failure occurred.
또한 상기한 것중 인장스프링은 설치시에 양단에 약간의 인장력을 주어 설치해야만 복귀시에 인장스프링이 이탈되는 것을 방지할 수 있는 데 이러한 작업을 보통 작업자의 근력에 의존하여 행하거나 설치되는 기계장치의 일부를 인장스프링의 설치를 고려하여 특별한 스프링텐션장치를 구비하도록 설계하여야 함으로 조립에 상당한 불편이 따랐으며, 비록 스프링텐션조절장치를 갖추더라도 장비자체가 고가이어서 널리 사용되지는 못하고 특별한 경우에만 사용되고 있는 실정이다.In addition, the above-mentioned tension spring should be installed by giving a slight tension to both ends at the time of installation to prevent the tension spring from deviating upon return, which is usually performed depending on the strength of the operator, Some parts were designed to have a special spring tension device in consideration of the installation of the tension spring, which caused considerable inconvenience.In spite of the spring tension control device, the equipment itself is expensive and is not widely used. It is true.
본 고안은 상기한 바와같은 제반 문제점들을 해소하고자 안출한 것으로 인장스프링의 장류길이를 임의로 조정할 수 있는 인장코일스프링 고정구를 제공하려는 데 그 목적이 있는 것이다.The object of the present invention is to provide a tension coil spring fixture capable of arbitrarily adjusting the length of the tension spring of the tension spring.
이러한 본 고안의 목적을 달성하기 위하여 인장코일스프링의 양단을 고정하는 인장코일스프링 고정구에 있어서, 상기 인장코일스프링의 일측된 스프링구멍에 인서팅너트를 결합수단에 의해 설치되고, 이 인서팅너트에 록크너트를 갖춘 조정볼트를 나사결합하는 한편, 상기 인장코일스프링의 타측단 스프링구멍에는 고리가 일체로 형성된 걸림쇠를 상기와 같은 결합수단에 의해 설치하여 인장코일 스프링 고정구가 제공된다.In the tension coil spring fixture for fixing both ends of the tension coil spring in order to achieve the object of the present invention, an inserting nut is installed in one spring hole of the tension coil spring by a coupling means, While screwing the adjusting bolt with the lock nut, the other end of the tension coil spring is provided with a tension coil spring fixture by installing a latch formed integrally with the ring by the coupling means as described above.
이하 본 고안에 따른 인장코일스프링 고정구의 실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, an embodiment of a tension coil spring fixture according to the present invention will be described in detail with reference to the accompanying drawings.

In the center, an inserting nut 31 having a female threaded hole 30 in the center is installed by a coupling means 40, and an adjusting bolt 51 having a lock nut 50 is screwed into the inserting nut 31. On the other hand, the other end spring hole 23 of the tension coil spring 21 is configured by installing the engaging chain (61) formed with the ring 60 is formed by the coupling means 40 as described above.
여기서 상기 결합수단(40)은 상기 인장코일스프링(21)의 코일가격(C)과 같은 나사피치(P)를 가지며, 이 인장코일스프링(21)의 감긴방향과 동일한 방향으로 형성된 숫나사산(32)을 상기 인서팅너트(31)의 외주면상에 형성하여 인서팅너트(31)와 인장코일스프링(21)이 나사결합되도록 구성된다.Wherein the coupling means 40 has a thread pitch (P) equal to the coil price (C) of the tension coil spring 21, the male thread 32 formed in the same direction as the wound direction of the tension coil spring (21) ) Is formed on the outer circumferential surface of the inserting nut 31 so that the inserting nut 31 and the tension coil spring 21 are screwed together.
그리고 이러한 인장코일스프링 고정구는 산업전반에 걸친 탄성을 요하는 장치에 적용될 수 있는 것이며, 특히 고속동작과 순간 동하중이 작용하는 예를들어, 제4도에 도시하는 바와같이 고속세폭직기(高速細幅織機)(70)의 일부 동작인 여러가닥의 선재를 교차시킬 때 고속회전운동하는 캠(도시않됨)에 의해 운동하는 종강 프레임(71)이 캠면에 강하게 밀착되면서 복귀시에 고속복귀를 실현하기 위한 리턴스프링(종강스프링)에 사용될수 있는 것이다.And such a tension coil spring fixture can be applied to a device that requires elasticity throughout the industry, in particular high speed action and instant dynamic load, for example, as shown in Figure 4 high-speed narrow loom The longitudinal frame 71, which is moved by a cam (not shown) which rotates at a high speed when intersecting several wires, which is a part of the operation of the wire 70, adheres strongly to the cam surface to realize high-speed return upon return. It can be used for return springs.
도면중 미설명 부호 70은 기계장치(고속세폭직기)이며, 72는 기계장치(70)의 스프링고정편이고, 73은 상기 조정볼트(51)의 볼트머리이며, 74는 스프링고정편(72)에 형성된 홈이다.In the drawings, reference numeral 70 denotes a mechanical device (high speed narrow loom), 72 is a spring fixing piece of the mechanical device 70, 73 is a bolt head of the adjusting bolt 51, 74 is a spring fixing piece 72 Formed grooves.
이상에서와 같은 본 고안의 작용을 설명한다.The operation of the present invention as described above will be described.
인장코일스프링(21)의 일측단에 설치된 걸림쇠(61)의 고리(60)을 기계장치(본 도면에서는 고속세폭직기를 예로 든다)(70)에 형성된 스프링가동편(71)에 걸고, 인장코일스프링(21)의 타측단에 설치된 조정볼트(51)를 트위스트방향으로 회전시켜 인서팅너트(31)로부터 조정볼트(51)를 충분히 빠져나오게 한 다음 기계장치(70)의 스프링고정편(72)에 횡으로 형성된 홈(74)을 통해 조정볼트(51)를 횡방향으로 진입시키게 되면, 조정볼트(51)가 홈(74)에 진입되어 볼트머리(73)가 걸리게 되며, 이 상태에서 조정볼트(51)를 조이게 되면, 처음에는 조정볼트(51)만 돌면서 진행하다가 어느시점에서 조정볼트(51)는 볼트머리(73)의 걸림에 의해 인서팅너트(31)와 함께 인장코일스프링(21)을 당기게 되며, 이때에 인장코일스프링(21)은 탄성을 갖게 되는것이다.The hook 60 of the clamp 61 provided at one end of the tension coil spring 21 is hooked on a spring movable piece 71 formed on a mechanical device (this example uses a high speed narrow loom) 70, and the tension coil spring. Rotate the adjusting bolt 51 provided at the other end of the shaft 21 in the twisting direction so that the adjusting bolt 51 is sufficiently pulled out from the inserting nut 31, and then to the spring fixing piece 72 of the mechanical device 70. When the adjustment bolt 51 enters the transverse direction through the groove 74 formed in the horizontal direction, the adjustment bolt 51 enters the groove 74 and the bolt head 73 is caught, and in this state the adjustment bolt ( When tightening 51, at first, only the adjusting bolt 51 is rotated, and at some point, the adjusting bolt 51 moves the tension coil spring 21 together with the inserting nut 31 by the bolt head 73. At this time, the tension coil spring 21 is to have elasticity.
즉, 인장코일스프링(21)의 설치시에는 인장코일스프링(21)이 자유길이를 가진 상태에서 횡으로 설치되고, 후에 일반체결공구를 이용하여 텐션을 임의로 조정함으로써 인장코일스프링(21)의 설치가 이루어지는 것이다.That is, when the tension coil spring 21 is installed, the tension coil spring 21 is installed horizontally with a free length, and then the tension coil spring 21 is installed by arbitrarily adjusting the tension using a general fastening tool. Will be made.
상기와 같은 상태에서 조정볼트(51)와 인서팅너트(31)간의 풀림을 방지하기 위해 조정볼트(51)에 구비된 록크너트(50)를 강하게 조이게 되면, 텐션조정이 끝난 인장코일스프링(21)의 이탈을 방지할 수 있게 되는 것이다.When the lock nut 50 provided in the adjusting bolt 51 is strongly tightened in order to prevent loosening between the adjusting bolt 51 and the inserting nut 31 in the above state, the tension coil spring 21 in which the tension is adjusted is completed. ) Will prevent the departure.
