오일씰 조립용 지그{CONNECTING JIG FOR OIL SEAL}Jig for oil seal assembly {CONNECTING JIG FOR OIL SEAL}

본 고안은 오일씰 조립용 지그에 관한 것으로, 더욱 상세하게는 액츄에이터용 슬라이딩 커플링 내에 오일씰을 조립하는 작업에서 오일씰을 손으로 고정하지 않고 별도의 지그를 이용하여 슬라이딩 커플링 내에 오일씰을 정위치에 간편하게 조립할 수 있도록 함과 아울러, 조립용 지그의 단부를 착탈 가능하게 결합시켜 슬라이딩 커플링의 사이즈 치수에 적합한 사이즈로 교체할 수 있도록 그 구조가 개선된 오일씰 조립용 지그에 관한 것이다.The present invention relates to a jig for assembling an oil seal, and more specifically, in the work of assembling an oil seal in a sliding coupling for an actuator, without fixing the oil seal by hand, a separate jig is used to easily fix the oil seal in the sliding coupling in place. It relates to a jig for assembling an oil seal whose structure is improved so that it can be assembled and replaced with a size suitable for the size of a sliding coupling by detachably coupling the end of the assembling jig.

일반적으로 오일씰은 자동차를 포함하여 여러 제품군의 모터 샤프트 또는 엔진 크랭크 샤프트 축에 장착되어, 샤프트를 타고 오일이 누유되는 것을 방지하도록 이루어진다. 특히 자동차 분야에서 사용되는 오일씰은 엔진룸 내부에 수용된 오일이 샤프트와 엔진룸 사이에 누설되는 것을 방지하거나, 외부로부터 유입되는 더스트를 방지하기 위한 목적으로 흔히 사용되고 있다.In general, oil seals are mounted on motor shafts or engine crankshaft shafts of various product groups, including automobiles, to prevent oil from leaking along the shaft. In particular, the oil seal used in the automobile field is commonly used for the purpose of preventing oil contained in the engine room from leaking between the shaft and the engine room or preventing dust from flowing in from the outside.

위와 같은 오일씰은 일반적으로 샤프트의 형상과 대응하도록 둥근 링 형태로 구성되면서, 외주면의 일면이 "ㄷ"자 형태로 개방되도록 형성될 수 있다. 물론, 오일씰은 사용되는 산업군에 따라 그 형상은 다양하게 이루어질 수 있으며, 오일씰이 샤프트에 직접 닿는 것을 포함하여 별도의 장치 등을 통해 결합되도록 이루어질 수도 있다.The above oil seal is generally configured in a round ring shape to correspond to the shape of the shaft, and may be formed so that one surface of the outer circumferential surface is opened in a “C” shape. Of course, the shape of the oil seal may vary according to the industrial group used, and the oil seal may be coupled through a separate device, including direct contact with the shaft.

또한 상기한 바와 같은 다양한 오일씰 중에서도 자동차에 내부에 삽입되는 오일씰은 한국공개특허공보 제10-2017-0073370호("엔진 크랭크 샤프트용 오일씰") 및 한국공개특허공보 제10-2017-0043752호("실링성이 향상된 오일씰")를 포함한 여러 선행기술문헌에 개시되어 있다. 이 중에서 한국공개특허공보 제10-2017-0043752호를 살펴보면 다음과 같다.In addition, among the various oil seals as described above, the oil seal inserted into the vehicle is disclosed in Korean Patent Application Laid-Open No. 10-2017-0073370 (“Oil Seal for Engine Crankshaft”) and Korean Patent Application Laid-Open No. 10-2017-0043752 (“ It is disclosed in several prior art documents including "oil seal with improved sealing properties"). Among them, Korean Patent Application Laid-Open No. 10-2017-0043752 is as follows.

상기한 오일씰은 씰바디, 서포트프레임, 메인립 및 더스트립을 포함하여 이루어질 수 있다. 그리고 상기 오일씰은 댐퍼풀리 및 체인커버 사이의 공간에 장착되는 것으로, 상기 댐퍼 풀리는 샤프트와 조립된 부품이다. 여기서 상기 씰바디는 'ㄷ'자 형태로 이루어지되 소재는 고무(Rubber)를 포함한 여러 가요성 부재로 이루어질 수 있으며, 상기 메인립 및 더스트립은 일단이 상기 씰바디에 고정되되 타단이 댐퍼풀리에 밀착되도록 이루어질 수 있다. 이에 따라 상기한 오일실은 오일 누유 및 더스트 침입을 방지하도록 이루어질 수 있다.The oil seal may include a seal body, a support frame, a main lip and a dust strip. And the oil seal is mounted in the space between the damper pulley and the chain cover, and the damper pulley is a part assembled with the shaft. Here, the seal body is formed in a 'C' shape, and the material may be made of various flexible members including rubber, and the main lip and the strip have one end fixed to the seal body and the other end attached to the damper pulley. It can be made to adhere. Accordingly, the oil seal may be formed to prevent oil leakage and dust intrusion.

상기한 오일씰은 천연가스 공급관리소의 액츄에이터 핸드휠 캡부분 누유를 방지하기 위해 사용되고 있다.The above-described oil seal is used to prevent leakage of the actuator handwheel cap portion of the natural gas supply management office.

그런데, 캡부분 누유가 발생할 경우, 캡을 분리시키고 핸드휠을 취외한 후에 액츄에이터 슬라이딩 커플링 내에 오일씰을 손으로 삽입하여 교체하고 있은, 슬라이딩 커플링의 부피가 작아서 손으로 고정하기 어렵고, 억지로 힘을 가해 고정시키거나 어느 한방향으로 힘을 가하게 되면 오일씰이 파손될 우려가 있다.However, when oil leakage occurs in the cap part, it is difficult to fix by hand because the volume of the sliding coupling, which is replaced by inserting the oil seal into the sliding coupling of the actuator by hand after removing the cap and removing the handwheel, is difficult, and force is applied. If it is fixed by applying force or force is applied in either direction, the oil seal may be damaged.

상기 연결볼트(300)는 상기 제2볼트체결공(220)에 나사체결되고, 단부가 상기 손잡이봉(100)의 제1볼트체결공(110)에 나사 체결되어 상기 끼움부재(200)를 상기 손잡이봉(100)에 착탈 가능하게 결합시키는 기능을 수행하게 된다.The connecting bolt 300 is screwed to the second bolt fastening hole 220, and the end is screwed to the first bolt fastening hole 110 of the handle bar 100 to secure the fitting member 200. It performs a function of detachably coupling to the handle bar (100).

이러한 구성을 갖는 본 고안은 도 3에 도시된 바와 같이, 액츄에이터의 핸드휠(10) 캡부분에 오일이 누설될 경우, 캡을 분해하여 슬라이딩 커플링(15) 내부를 개방시킨 후에, 슬라이딩 커플링(15) 내에 손상된 오일씰(50)을 외측으로 인출한다.As shown in FIG. 3, the present invention having such a configuration is, when oil leaks to the cap portion of the handwheel 10 of the actuator, disassemble the cap to open the sliding coupling 15, then the sliding coupling (15) Take out the damaged oil seal (50) to the outside.

이어서, 조립하고자 하는 오일씰(50)의 중공(52) 내경과 적합한 내경의 단턱부(210)가 형성된 끼움부재(200)를 선택하고, 손잡이봉(100)의 상측에 안착시키고, 제1,2볼트체결공(110,220)을 동일 수직선상에 배치시킨 후에, 연결볼트(300)로 끼움부재(200)와 손잡이봉(100)을 연결시킨다.Next, select the fitting member 200 in which the stepped portion 210 of the hollow 52 inner diameter and the appropriate inner diameter of the oil seal 50 to be assembled is formed, and seat it on the upper side of the handle bar 100, and first and second After arranging the bolt fastening holes 110 and 220 on the same vertical line, the fitting member 200 and the handle bar 100 are connected with the connecting bolt 300 .

상기 손잡이봉(100)과 결합된 끼움부재(200)의 상측에 오일씰(50)을 안착시키면, 상기 단턱부(210)가 상기 오일씰(50)의 중공(52) 내로 진입되어 끼움 결합된다.When the oil seal 50 is seated on the upper side of the fitting member 200 coupled to the handle rod 100 , the stepped portion 210 enters into the hollow 52 of the oil seal 50 and is fitted.

이어서, 상기 오일씰(50)이 결합된 단턱부(210)를 슬라이딩 커플링(15) 내부로 진입시키고 손잡이봉(100)이 슬라이딩 커플링(15)의 상측을 향하도록 기립시키면, 상기 단턱부(210)에 끼워진 오일씰(50)이 단턱부(210)로부터 빠져나와 슬라이딩 커플링(15)의 내부로 진입되면서 조립된다.Then, when the stepped portion 210 to which the oil seal 50 is coupled enters the sliding coupling 15 and stands up so that the handle rod 100 faces the upper side of the sliding coupling 15, the stepped portion ( The oil seal 50 fitted in the 210 is assembled while coming out of the stepped portion 210 and entering the sliding coupling 15 .

이어서 손잡이봉(100)을 들어 올린 후에, 오일씰(50)이 슬라이딩 커플링(15) 내에 정위치 조립되었는지를 확인한 후에 캡을 다시 슬라이딩 커플링(15)에 결합시키면 오일씰(50)의 교체작업이 완료된다.Subsequently, after lifting the handle bar 100 , after confirming that the oil seal 50 is assembled in the correct position in the sliding coupling 15 , and then coupling the cap to the sliding coupling 15 again, the replacement operation of the oil seal 50 is is done

따라서, 본 고안은 오일씰(50)의 교체작업시 오일씰(50)이 천연가스 공급관리소의 액츄에이터 핸드휠(10)의 슬라이딩 커플링(15) 내에 손을 사용하지 않고 지그를 이용하여 간편하게 조립할 수 있도록 함과 아울러, 끼움부재(200)와 손잡이봉(100)이 착탈 가능하게 결합되어 사이즈가 서로 다른 오일씰(50)에도 적용할 수 있는 유용한 이점을 갖는다.Therefore, in the present invention, when replacing the oil seal 50, the oil seal 50 can be easily assembled using a jig without using hands in the sliding coupling 15 of the actuator handwheel 10 of the natural gas supply management office. In addition, the fitting member 200 and the handle bar 100 are detachably coupled to each other to have a useful advantage that can be applied to the oil seals 50 of different sizes.
