본 발명은 환체의 탄성력 테스트용 지그에 관한 것으로, 특히 연동척의 조오(JAW)에 로드셀(Load Cell)을 설치하고 그 끝단에 환체의 일종인 스프링클램프를 걸어서 조오(JAW)를 방사방향으로 조이거나 풀므로써 로드셀로부터 출력되는 전기적인 값을 읽어서 환체의 탄성력을 측정할 수 있도록 해주는데 사용되는 환체의 탄성력 테스트용 지그에 관한 것이다.The present invention relates to a jig for testing the elastic force of the ring, in particular, the load cell (JAW) of the interlocking chuck is installed and the jaw (Jaw) is radially tightened by hanging a spring clamp, which is a kind of ring at the end thereof. The present invention relates to a jig for testing the elastic force of a ring used to measure the elastic force of the ring by reading an electrical value output from the load cell.

일반적으로 부품류는 사용자에게 이 부품에 대한 구체적인 수명데이타를 알려주고 불량의 여부를 판별하기 위해 시험을 거친다.In general, parts are tested to inform the user of the specific life data of the part and to determine whether they are defective.

그중 환체(環體)의 일종인 스프링클램프는 변위량에 따른 탄성력이 어느 정도 되는가를 알아야 호스(도시않됨) 등에 물어서 설치될때 호스(도시않됨)에 작용시켜야 하는 적절한 가압력을 가진 스프링클램프를 선택하여 사용할 수 있게 된다.Among them, the spring clamp, which is a kind of ring body, needs to know how much elastic force according to the displacement amount, so it is necessary to select a spring clamp with appropriate pressing force to act on the hose (not shown) when it is installed by biting a hose (not shown). It becomes possible.

그러나 종래에 스프링클램프의 탄성력을 테스트하는 장비는 단순히 스프링클램프의 일측을 고정시키고 타측에서 한개의 로드셀을 이용하여 손으로 당기면서 측정하는 방법을 취하고 있으므로 스프링클램프의 전체 협지면에 걸쳐서 작용하는 탄성력의 측정은 불가능하였으며, 한지점만을 측정하므로 부정확한 데이타가 산출되는 문제점이 있었다.However, the conventional equipment for testing the spring force of the spring clamp simply measures one side of the spring clamp and pulls it by hand using one load cell on the other side. Therefore, the elastic force acting over the entire clamping surface of the spring clamp is applied. It was impossible to measure and there was a problem that incorrect data was calculated because only one point was measured.

이상에서와 같은 본 발명의 실시예에 따른 작용·효과를 설명한다.The operation and effect according to the embodiment of the present invention as described above will be described.

환체(70)인 스프링클램프의 탄성력을 측정하려고 할 경우에 먼저 이 환체(70)의 내주면(71)에 각 걸림부재(85)(86)(87)에 형성된 걸림돌기(93)(94)(95)의 걸림면(25)(35)(45)이 접촉할 수 있도록 연동척(50)의 조오조정부(50a)를 회전시켜 조오(10)(11)(12)를 연동척(50)의 중심(C)으로 모으면서 이 조오(10)(11)(12)가 상기 환체(70)의 내주면(71)의 내경 크기보다 상기 각 걸림면(25)(35)(45)에 모두 외접하는 외접원의 직경이 작게 되었을 때 이 환체(70)를 걸림돌기(93)(94)(95)에 끼우게 되며, 받침부(90)(91)(92)에 의해 지지된 상태로 있게 된다.In the case of trying to measure the elastic force of the spring clamp which is the ring body 70, first, the locking protrusions 93 and 94 are formed on the respective engaging members 85, 86 and 87 on the inner circumferential surface 71 of the ring body 70. The jaws 10, 11, 12 of the interlocking chuck 50 are rotated by rotating the jaw adjusting unit 50a of the interlocking chuck 50 so that the engaging surfaces 25, 35, 45 of the 95 may contact each other. The jaws 10, 11, 12 are circumscribed to each of the engaging surfaces 25, 35, 45 more than the inner diameter of the inner circumferential surface 71 of the annulus 70 while being collected at the center C. When the diameter of the circumscribed circle becomes small, the annular body 70 is fitted to the engaging protrusions 93, 94, 95, and is supported by the supporting parts 90, 91, 92.

이 상태에서 연동척(50)의 조오조정부(50a)를 처음과는 반대방향으로 회전시키게 되면, 각 조오(10)(11)(12)가 중심(C)에서 부터 멀어지면서 환체(70)인 스프링클램프를 외측으로 당기게 된다.In this state, when the jaw adjustment unit 50a of the linkage chuck 50 is rotated in the opposite direction to the first, each jaw 10, 11, 12 is moved away from the center C, and the ring 70 is rotated. The spring clamp is pulled outward.

이때 스프링클램프는 탄성반력을 갖게 되며, 동시에 로드셀(20)(30)(40)의 측정단(21)(31)(41)도 당겨지게 된다.At this time, the spring clamp has an elastic reaction force, and at the same time, the measuring ends 21, 31 and 41 of the load cells 20, 30 and 40 are also pulled out.

상기와 같은 작용에 의해 로드셀(20)(30)(40)의 각 커넥터부(53)(54)(55)에 접속된 신호선(99)에는 전기적인 신호값이 출력되어 표시기(도시않됨)에 입력되며, 이 표시기(도시않됨)는 시각적인 기호로써 측정자에게 알려주게 된다.By the above-described action, an electric signal value is output to the signal line 99 connected to each of the connector parts 53, 54, 55 of the load cells 20, 30, 40, to an indicator (not shown). This indicator (not shown) informs the operator as a visual symbol.

이상에서와 같은 본 발명은 스프링클램프와 같은 환체의 탄성력 측정을 여러지점에서 동시에 할 수 있으므로 산출되는 탄성력이 정확하게 되며, 측정시 연동척의 조오를 조정하는 것만으로 측정이 가능하므로 측정시의 불편을 덜 수 있는 효과가 있는 것이다.As described above, the present invention can measure the elastic force of the annular body such as a spring clamp at several points at the same time, so that the calculated elastic force is accurate, and it is possible to measure only by adjusting the jaw of the interlock chuck during measurement, thereby reducing the inconvenience of measuring. It can be effective.
