In other words, the timing chain 502 is wound around the crankshaft sprocket 504, and the tensioner arm 506 and the chain guide 508 are pivotally supported on both sides of the timing chain 502.

상기와 같이 실린더블록(500)에 타이밍체인(502)을 가조립한 상태에서 도 2와 같이 실린더블록(500)에 체인커버(510)를 장착한다. 이후, 도 3과 같이 실린더헤드(512)를 실린더블록(500)에 조립하게 되는데, 상기 실린더헤드(512)는 도 4에 도시된 바와 같이 하측부분에 타이밍체인(502)이 관통되도록 연통구멍(514)이 형성되고, 상기 연통구멍(514)은 사이드레일(516)에 의해 닫힌 구조이다.In the state where the timing chain 502 is temporarily assembled to the cylinder block 500 as described above, the chain cover 510 is mounted to the cylinder block 500 as shown in FIG. 2. Thereafter, as shown in FIG. 3, the cylinder head 512 is assembled to the cylinder block 500, and the cylinder head 512 has a communication hole such that the timing chain 502 penetrates through the lower portion as shown in FIG. 4. 514 is formed, and the communication hole 514 is closed by the side rails 516.

상기 사이드레일(516)은 실린더블록(500)에 결합된 상기 체인커버(510)의 상측에 결합되어 실링(SEALING)된다.The side rail 516 is coupled to the upper side of the chain cover 510 coupled to the cylinder block 500 is sealed (SEALING).

이후, 상기 타이밍체인(502)을 캠샤프트스프로켓에 걸어서 타이밍체인(502) 조립작업을 완료하게 된다.Thereafter, the timing chain 502 is hooked on the cam shaft sprocket to complete the assembly of the timing chain 502.

상기한 바와 같이 타이밍체인(502)의 조립작업이 이루어지는 과정에서, 상 기 실린더헤드(512)를 실린더블록(500)에 조립하기 위해서는 상기 타이밍체인(502)과 텐셔너암(506) 및 체인가이드(508)가 상기 연통구멍(514)을 통과하도록 해야 하는데, 상기 텐셔너암(506)과 체인가이드(508)는 실린더블록(500)에 피봇지지되어 움직이고 타이밍체인(502)은 하측으로 흘러내리려는 경향이 있으므로 상기 연통구멍(514)을 통과시키켜서 조립작업을 수행하기가 쉽지 않다.In the process of assembling the timing chain 502 as described above, in order to assemble the cylinder head 512 to the cylinder block 500, the timing chain 502, the tensioner arm 506 and the chain guide ( 508 must pass through the communication hole 514, the tensioner arm 506 and chain guide 508 is pivotally supported by the cylinder block 500 and the timing chain 502 tends to flow down Therefore, it is not easy to carry out the assembly work by passing the communication hole 514.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 5를 참조하면, 본 발명 실시예의 지그(1)는 텐셔너암(3)에 회전 가능하게 끼워지는 돌기(5)를 구비한 제1레버암(7)과; 체인가이드(9)에 회전 가능하게 끼워지는 돌기(11)를 구비하고, 상기 제1레버암(7)과 힌지로 연결된 제2레버암(13)과; 상기 제1레버암(7)의 돌기(5)와 상기 제2레버암(13)의 돌기(11) 사이의 거리가 좁아지는 방향으로 상기 제1레버암(7)과 제2레버암(13)을 탄성 지지하도록 설치된 토션스프링(15)과; 상기 제1레버암(7)과 제2레버암(13)에 연결된 체인지지수단을 포함한 구성이다.5, the jig 1 of the embodiment of the present invention includes a first lever arm 7 having a projection 5 rotatably fitted to the tensioner arm 3; A second lever arm (13) having a projection (11) rotatably fitted to the chain guide (9), the hinge being connected to the first lever arm (7); The first lever arm 7 and the second lever arm 13 in a direction in which the distance between the protrusion 5 of the first lever arm 7 and the protrusion 11 of the second lever arm 13 is narrowed. A torsion spring (15) installed to elastically support; The first lever arm 7 and the second lever arm 13 is configured to include a chain support means connected.

본 실시예에서 상기 체인지지수단은 하단은 상기 제1레버암(7)에 힌지로 연결되고 상단은 타이밍체인(19)이 걸리도록 뾰족하게 형성된 제1걸림암(17)과; 하단이 상기 제2레버암(13)에 힌지로 연결되고, 중간부분이 상기 제1걸림암(17)과 교차하면서 교차된 부분이 힌지로 연결되며, 상단은 타이밍체인(19)이 걸리도록 뾰족하게 형성된 된 제2걸림암(21)으로 구성하였다.In the present embodiment, the chain support means has a lower end connected to the first lever arm (7) by a hinge and the upper end has a first catching arm (17) sharply formed to take the timing chain (19); A lower end is connected to the second lever arm 13 by a hinge, the middle part intersects with the first catching arm 17, and an intersecting part is connected by a hinge, and the upper end is pointed to take the timing chain 19. The second catching arm 21 was formed to be configured.

즉, 상기 체인지지수단은 상기 제1걸림암(17)과 제2걸림암(21)이 서로 가위형상으로 힌지를 통해 교차하여 결합된 상태에서, 제1걸림암(17)과 제2걸림암(21)의 하단이 각각 상기 제1레버암(7)과 제2레버암(13)에 힌지로 결합된 구조인 것이다.That is, the chain support means is the first locking arm 17 and the second locking arm 21 in a state in which the first locking arm 17 and the second locking arm 21 cross each other through a hinge shape and are coupled to each other. Lower ends of the 21 are structured to be hinged to the first lever arm 7 and the second lever arm 13, respectively.

따라서, 상기 제1레버암(7)과 제2레버암(13)이 상기 토션스프링(15)에 의해 회동할 때 상기 제1걸림암(17)과 제2걸림암(21)은 상기 제1레버암(7)과 제2레버암(13)의 회동운동을 방해하지 않고 허용하는 상태를 유지하게 된다.Accordingly, when the first lever arm 7 and the second lever arm 13 are rotated by the torsion spring 15, the first catching arm 17 and the second catching arm 21 may be formed in the first lever arm. The state of allowing the lever arm 7 and the second lever arm 13 without disturbing the rotational movement is maintained.

상기 제2레버암(13)의 돌기(11)는 상기 체인가이드(9)의 볼트마운팅홀(27)에 삽입되는데, 상기 체인가이드(9)의 볼트마운팅홀(27)은 상기 체인가이드(9)의 상측을 실린더헤드(25)에 고정하기 위해 종래부터 체인가이드(9)에 형성되어 있는 구멍이다.The protrusion 11 of the second lever arm 13 is inserted into the bolt mounting hole 27 of the chain guide 9, and the bolt mounting hole 27 of the chain guide 9 is the chain guide 9. In order to fix the upper side of the to the cylinder head 25, it is a hole formed in the chain guide (9).

한편, 상기 제1레버암(7)의 돌기(5)는 상기 텐셔너암(3)에 회전 가능한 상태로 삽입되어야 하는데, 텐셔너암(3)에는 통상 상기 제1레버암(7)의 돌기가 삽입될만한 구멍이 구비되어 있지 않으므로, 상기 제1레버암(7)의 돌기가 회전 가능한 상태로 삽입되도록 텐셔너암(3)에 돌기삽입홀(29)을 형성한다(도 6참조).
Meanwhile, the protrusion 5 of the first lever arm 7 should be inserted into the tensioner arm 3 in a rotatable state, and the protrusion of the first lever arm 7 is usually inserted into the tensioner arm 3. Since there is no suitable hole, a projection insertion hole 29 is formed in the tensioner arm 3 so that the projection of the first lever arm 7 can be inserted in a rotatable state (see FIG. 6).

타이밍체인(19)의 조립시에, 타이밍체인(19)과 텐셔너암(3) 및 체인가이드(9)를 실린더블록(31)에 장착한 후, 텐셔너암(3)과 체인가이드(9)를 도 6과 같은 상태로 중앙으로 모아서, 상기 지그(1)의 제1레버암(7)과 제2레버암(13)의 돌기들을 상기 돌기삽입홀과 볼트마운팅홀(27)에 끼워서 도 7과 같은 상태가 되도록 한다.When assembling the timing chain 19, the timing chain 19, the tensioner arm 3 and the chain guide 9 are mounted on the cylinder block 31, and then the tensioner arm 3 and the chain guide 9 are mounted. 6, the projections of the first lever arm 7 and the second lever arm 13 of the jig 1 are inserted into the projection insertion hole and the bolt mounting hole 27. Try to be in the same state.

참고로, 도 6과 도 7에서는 텐셔너암(3)과 체인가이드(9) 사이의 타이밍체인(19)이 생략되어 있다.For reference, in FIGS. 6 and 7, the timing chain 19 between the tensioner arm 3 and the chain guide 9 is omitted.

이후, 작업자는 실린더블록(31)에 체인커버(33)를 장착하여 도 8과 같은 상태가 되도록 한다. Afterwards, the worker mounts the chain cover 33 to the cylinder block 31 so as to be in a state as shown in FIG. 8.                     

상기와 같은 상태에서는 타이밍체인(19)과 텐셔너암(3) 및 체인가이드(9)가 모두 상기 지그(1)에 의해 자유로운 유동이 억제되고, 또한 실린더블록(31)의 중앙쪽으로 모여있는 상태이므로, 실린더헤드(25)의 연통구멍을 통해 통과하기가 매우 용이한 상태가 확보된다.In the above state, since the timing chain 19, the tensioner arm 3, and the chain guide 9 are both freely inhibited by the jig 1 and are gathered toward the center of the cylinder block 31, The state which is very easy to pass through the communication hole of the cylinder head 25 is ensured.

작업자는 상기와 같은 상태에서 도 9에 도시된 바와 같이 실린더헤드(25)의 연통구멍으로 상기 지그(1)가 설치된 부분을 통과시킴으로써, 실린더헤드(25)를 실린더블록(31)에 용이하게 위치시켜서 실린더헤드(25) 장착작업 및 타이밍체인(19) 설치작업을 매우 손쉽게 완료할 수 있다.In the above state, the operator passes the portion in which the jig 1 is installed through the communication hole of the cylinder head 25, as shown in FIG. 9, thereby easily positioning the cylinder head 25 to the cylinder block 31. By doing so, the cylinder head 25 mounting work and timing chain 19 installation work can be completed very easily.

이상과 같이 본 발명에 의한 지그는 실린더블록에 체인커버 장착이 완료된 상태에서 타이밍체인이 통과되는 연통구멍을 가진 실린더헤드를 실린더블록에 장착할 때, 상기 실린더헤드의 연통구멍을 통해 타이밍체인과 체인가이드 및 텐셔너암이 용이하게 통과할 수 있도록 보조함으로써, 엔진의 조립작업성을 크게 향상시킬 수 있도록 한다.As described above, the jig according to the present invention has a timing chain and a chain through a communication hole of the cylinder head when a cylinder head having a communication hole through which the timing chain passes through the cylinder block is installed in the cylinder block. By assisting the guide and the tensioner arm to pass easily, it is possible to greatly improve the assembly workability of the engine.
