본 발명은 오-링 테스트 장비에 관한 것으로 더욱 상세하게는 각종 기계장비 등에 개재되는 오-링에 있어서; 상기 오-링의 실제 장착시 요구되는 기계적 성질을 테스트하는 오-링 테스트 장비의 개선안에 관한 것이다.The present invention relates to an o-ring test equipment, and more particularly, to an o-ring interposed in various mechanical equipment and the like; An improvement on o-ring test equipment for testing the mechanical properties required for the actual mounting of the o-ring.

일반적으로 오-링은 기계장비나 작동부에서 각종 유체의 누유를 방지하는 기밀 유지를 위해 적용되는 것으로, 소정의 두께를 가지는 환형테 형상으로 적용부품에 따라 다양한 재질과 직경 단면을 형성한다.In general, the o-ring is applied to maintain the airtightness to prevent the leakage of various fluids in the machine or the operating portion, and has a variety of materials and diameter cross-section according to the application in an annular frame shape having a predetermined thickness.

이와 같은 오-링은 생산 후 성능시험은 물론 품질개선을 위해 다양한 성능테스트를 거치게 되는데, 특히 오-링에 가장 많이 적용된 압축변형시험과 내마모성 시험을 거치게 된다.Such O-rings undergo various performance tests for quality improvement as well as post-production performance tests. Especially, the O-rings undergo the compression deformation test and the wear resistance test that are most applied to the O-rings.

상기와 같은 압축변형시험 및 내마모성 시험을 위해서는 별도의 테스트 장비가 요구되며, 그 가운데 도 1에 도시된 도면은 압축변형시험을 위한 테스트 장비의 일예이다.Separate test equipment is required for the compression deformation test and the abrasion resistance test as described above, and the drawing shown in FIG. 1 is an example of the test equipment for the compression deformation test.

이러한 압축변형을 테스트하기 위해서는 먼저 볼트/너트 체결된 테스트 장비를 분리한 후, 그 상간으로 테스트를 위한 오-링 샘플을 안치하고, 이어 작업자가 수동으로 볼트/너트를 재체결하여 일정한 압력을 오-링에 가하게 된다.To test this compression deformation, first remove the bolt / nut clamped test equipment, then place an o-ring sample for testing between phases, and then manually retighten the bolt / nut to maintain a constant pressure. -Applied to the ring.

It consists of a downplate 36.

상기 고정플레이트(32)는 로워플레이트(31)상에 형성되는 것으로, 그 내방으로는 오-링의 실제 장착된 환경과 동일한 온도를 설정하기 위한 히터(37)가 내장되고, 최상방에는 그 단면이 사다리꼴을 이루는 그루브(groove;38)가 형성된다.The fixed plate 32 is formed on the lower plate 31, and the heater 37 for setting the same temperature as the actual mounting environment of the o-ring inside the built-in, the upper end of the cross section is A trapezoidal groove 38 is formed.

상기와 같은 고정플레이트(32) 상방에 개재되는 업/다운플레이트(36)는 고정플레이트(32)에 상응하는 규격의 평판형으로, 업/다운플레이트(36)를 왕복 운동시키기 위한 동력원인 작동기구(35)가 장착된 어퍼플레이트(33)와 고정플레이트(32)가 장착된 로워플레이트(31)를 연결하는 가이드샤프트(34)를 통해 개재된다.The up / down plate 36 interposed above the fixed plate 32 is a flat plate of a standard corresponding to the fixed plate 32, and an operating mechanism that is a power source for reciprocating the up / down plate 36. The upper plate 33 on which the 35 is mounted and the lower plate 31 on which the fixed plate 32 is mounted are interposed through the guide shaft 34.

뿐만 아니라, 업/다운플레이트(36) 역시 고정플레이트(32)와 같이 오-링 테스트 조건을 충족하기 위해 히터(미도시)가 내장된다.In addition, the up / down plate 36 also includes a heater (not shown) to meet the O-ring test conditions, such as the fixed plate 32.

상기와 같은 본 발명인 오-링 테스트 장비(1)는,O-ring test equipment 1 of the present invention as described above,

먼저 도 4에서와 같이 로워플레이트(31)상에 형성된 그루브(38)에 테스트를 하고자 하는 오-링(100) 시편을 고정하고, 이어 작업자는 테스트 내용에 따라 컨트롤부(20)를 통해 입력한 후 테스트 장비를 구동한다.First, the O-ring 100 specimen to be tested is fixed to the groove 38 formed on the lower plate 31 as shown in FIG. 4, and then the operator inputs the control part 20 according to the test contents. Then run the test equipment.

The pressure is adjusted to drive the air cylinder which is the operating mechanism 35.

이처럼 에어실린더가 작동함에 따라 업/다운플레이트(36)가 고정플레이트(32)상방으로 다운하며 설정된 압력으로 고정플레이트(32) 그루브(38)에 개재된 오-링(100)을 일정시간동안 가압한다.As the air cylinder operates as described above, the up / down plate 36 descends above the fixed plate 32 and presses the O-ring 100 interposed in the fixed plate 32 groove 38 at a predetermined pressure for a predetermined time. do.

상기와 같은 상황에서 테스트의 내용이 압축성능 시험일 경우 설정된 압력에서 일정시간동안 에어실린더를 통한 업/다운플레이트(36)에 하중을 전달하여 고정플레이트(32)에 장착된 오-링(100)에 압축하중이 가해지도록 한다.In the above situation, when the test content is the compression performance test, the load is transferred to the up / down plate 36 through the air cylinder for a predetermined time at the set pressure to the O-ring 100 mounted to the fixed plate 32. Allow compressive loads to be applied.

이 후 업/다운플레이트(36)를 고정플레이트(32)로부터 이격시키고, 고정플레이트(32) 그루브(38)에 장착된 오-링(100)을 분리하여 테스트 전 오-링과 테스트 후 오-링의 형태 변형이나 치수 등 기계적 성질 변화를 측정한다.Thereafter, the up / down plate 36 is spaced apart from the fixed plate 32, and the o-ring 100 mounted on the fixed plate 32 groove 38 is removed to test the o-ring before the test and the after-test. Measure changes in mechanical properties such as ring deformation and dimensions.

더불어 테스트내용이 내마모성 테스트일 경우 업/다운플레이트(36)는 일정압력으로 반복하여 고정플레이트(32) 상에 장착된 오-링과 접촉하여 오-링의 마모도를 측정하게 된다.In addition, when the test content is a wear resistance test, the up / down plate 36 is repeatedly contacted with the O-ring mounted on the fixed plate 32 at a constant pressure to measure the degree of wear of the O-ring.

이상과 같은 본 발명인 오-링 테스트 장비는 기존 수작업을 통해 수행하던 오-링 테스트를 전자제어에 의한 자동화로 가능하도록 하여 테스트 장비의 작동이 용이함은 물론 테스트 결과의 신뢰도 향상을 이룰 수 있다.O-ring test equipment of the present invention as described above enables the O-ring test performed through the existing manual operation by automation by electronic control, it is possible to facilitate the operation of the test equipment as well as to improve the reliability of the test results.

나아가, 단일 장비를 이용하여 압축변형 테스트와 내마모성 테스트를 동시에 실시가능하여 테스트를 위한 시간단축과 작업의 용이함을 구현할 수 있는 유용한 발명이다.Furthermore, it is a useful invention that can implement the compression deformation test and the abrasion resistance test at the same time using a single device to realize a shortening of time for test and ease of operation.
