본 고안은 용접지그에 관한 것으로, 특히 LNG운반선의 화물창고 내부의 코너에 설치되는 앵글피스를 용접부위에 밀착시켜 용접할 수 있도록 고정하는 앵글피스 설치용 용접지그에 관한 것이다.The present invention relates to a welding jig, and more particularly to an angle piece installation welding jig for fixing the angle piece installed in the corner of the cargo warehouse of the LNG carrier in close contact with the welding site.
일반적으로, LNG운반선의 건조시 화물창고 내부에 맴브레인(MEMBRANE)을 설치하게 된다. 이 맴브레인의 코너부에는 앵글피스가 설치되며, 이때 앵글피스는맴브레인에 용접하여 설치된다. 특히 앵글피스는 1,2㎜두께의 스텐레스 스틸(SUS 30.4C)로서 90°로 절곡되어 있다.In general, a membrane (MEMBRANE) is installed inside the cargo warehouse when the LNG carrier is built. An angle piece is installed at the corner of this membrane, and the angle piece is installed by welding to the membrane. In particular, the angle piece is bent at 90 degrees as stainless steel (SUS 30.4C) having a thickness of 1,2 mm.
이와 같은 앵글피스는 맴브레인의 주름에 맞도록 얹어 놓고 용접을 하게 된다. 특히 앵글피스의 용접에는 용가재를 사용치 않고 모재를 직접 놓여 붙이는 티그(TIG)용접을 하게 된다. 이때, 용접부위에는 틈새(GAP)가 발생하지 않도록 해야 한다. 따라서, 용접작업시 보조자가 막대로 앵글피스를 눌러 용접부위가 밀착되도록 하면서 택(TACK)용접을 한다.Such angle pieces are placed to match the wrinkles of the membrane and welded. In particular, the welding of the angle piece is a TIG welding that directly places the base material without using filler metal. At this time, a gap should not be generated in the welded part. Therefore, during welding operation, the assistant presses the angle piece with a rod to perform tack welding while keeping the welding portion in close contact.
그러나, 이와 같은 용접작업은 반드시 앵글피스를 눌러 밀착시켜주는 보조자가 필요하므로 2인 1조의 작업이 되어 인력방비가 뒤따른다. 또한, 보조자가 항상 동일한 강도로 앵글피스를 누르지 못하므로 용접부위가 고르지 못한 문제점이 있었다.However, such a welding operation necessarily requires an assistant to press the angle piece in close contact with each other, so the work of two pairs of personnel defense. In addition, since the assistant does not always press the angle piece with the same strength, there was a problem that the welded portion is uneven.
따라서, 본 고안의 목적은 LNG 운반선에서 화물창고의 앵글피스를 설치하는 용접작업시 지그를 사용하여 용접모재를 고정함으로써 용접을 용이하게 할 수 있도록 고안된 앵글피스 설치용 용접지그를 제공함에 있다.Accordingly, an object of the present invention is to provide an angle piece installation welding jig designed to facilitate welding by fixing the welding base material using a jig during the welding operation for installing the angle piece of the cargo warehouse in the LNG carrier.
이와 같은 목적을 달성하기 위한 본 고안에 따른 앵글피스 설치용 용접지그는 양단부가 ㄷ자로 절곡되며 중앙부에 압착부재 수용홈이 형성된 한쌍의 지지대와, 상기 지지대를 연결하며 양단이 소정의 각도로 절곡되고 압착부재가 고정되는 압착부재 수용홈이 형성된 연결부재를 구비한 몸체를 구비하고 있다. 상기 몸체에 형성된 상하압착부재 수용홈에 고정되며, 앵글피스의 상하를 고정하는 한쌍의 상하압착부재와, 상기 좌우압착부재 수용홈에 고정되며, 앵글피스의 좌우를 압착고정하는 한쌍의 좌우압착부재를 구비한 고정수단을 구비하고 있다.The welding jig for angle piece installation according to the present invention for achieving the above object is a pair of supports, both ends of which are bent by the letter C and the pressing member receiving groove is formed in the center, connecting the support and both ends are bent at a predetermined angle and pressed It has a body having a connecting member formed with a pressing member receiving groove to which the member is fixed. A pair of upper and lower pressing members fixed to the upper and lower pressing member receiving grooves formed in the body and fixed to the upper and lower sides of the angle piece, and fixed to the left and right pressing member receiving grooves, and a pair of left and right pressing members for pressing and fixing the left and right sides of the angle piece. It is provided with a fixing means having a.
이하, 첨부된 도면을 참조하여 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 따른 앵글피스 설치용 용접지그를 나타낸 사시도이다. 도시된 바와 같이, 몸체(10)는 상하대칭의 지지대(20)와 좌우대칭의 연결부재(30)로 구성되어 있다. 지지대(20)는 양측단이 ㄷ자로 절곡된 두개의 프레임으로 형성되어 있다. 이 지지대(20)의 양단부상에는 고정판(21)이 형성되어 있으며, 이곳에는 용접시 몸체(10)를 지지할 수 있도록 고정하는 고정홈(22)이 형성되어 있다. 고정홈(22)은 동일방향으로 연통되게 형성되어 맴브레인의 걸림구(미도시)에 삽입되어 고정된다. 더우기, 이 지지대(20)의 중앙부에는 상하압착부재(40)가 삽통고정되는 제1고정홈(23)이 형성되어 있다.1 is a perspective view showing a welding jig for installing an angle piece according to the present invention. As shown, the body 10 is composed of a support 20 of the upper and lower symmetry and the connecting member 30 of the left and right symmetry. The support 20 is formed of two frames in which both ends are bent at the letter “C”. Fixing plates 21 are formed on both ends of the support 20, and fixing grooves 22 are formed to fix the bodies 10 at the time of welding. Fixing groove 22 is formed in communication in the same direction is inserted into the locking hole (not shown) of the membrane is fixed. Moreover, the first fixing groove 23 is formed in the center of the support 20, the upper and lower pressing members 40 are inserted into the fixing.
지지대(20)의 상하프레임은 연결부재(30)인 좌우프레임으로 형합되어 있다. 연결부재(30)는 동일한 두개의 좌우프레임으로 구성되어 있으며, 각 프레임은 양단이 몸체가 코너부에 밀착되도록 적절한 각도로 절곡되어 있다. 연결부재(30)는 또한 일정한 간격을 이격하여 나란하게 양단이 지지대(20)인 상하프레임에 고착되어 있다. 결국, 이 연결부재(30)이 절곡으로 인하여 상하프레임이 직각으로 위치한다.The upper and lower frames of the support 20 are molded into left and right frames that are the connecting members 30. The connection member 30 is composed of two identical left and right frames, and each frame is bent at an appropriate angle so that both ends are in close contact with the corner portion. The connection member 30 is also fixed to the upper and lower frames at both ends of the support 20 side by side at regular intervals. As a result, the upper and lower frames are positioned at right angles due to bending of the connecting member 30.
한편, 연결부재(30)인 좌우프레임의 중앙부에는 좌우압착부재(50)가 삽입고정되는 제2수용홈(미도시)이 형성되어 있다. 도시된 고정수단인 상하, 좌우압착부재에 대해서는 제2도를 참조하여 상세히 설명한다.On the other hand, the second receiving groove (not shown) is formed in the center of the left and right frame that is the connection member 30 is inserted and fixed to the left and right compression member (50). The upper, lower, left and right pressing members, which are illustrated fixing means, will be described in detail with reference to FIG. 2.
제2a도는 좌우압착부재가 몸체에 고정된 상태를 확대하여 나타낸 확대부분단면도이고, 제2b도는 상하 압착부재가 몸체에 설치된 상태를 나타낸 확대부분단면도이다. 제2a도에서, 몸체(10)에는 너트(51)의 상단부가 삽입고정되어 있다. 이 너트(51)에는 볼트(52)가 나삽되어 회동함으로써 그 하부에 위치한 밀착대(53)를 밀어 앵글피스를 압착한다. 물론, 밀착대(53)는 일부분이 너트(51)에 삽입되어 있으며, 이 밀착대(53)는 직선 왕복운동한다. 특히 볼트(52)의 회전에 다른 밀착대(53)의 회전을 방지하기 위하여 너트(51)에는 안내홈(54)이 압착방향을 따라 직선으로 형성되어 있다.Figure 2a is an enlarged partial cross-sectional view showing an enlarged state in which the left and right compression member is fixed to the body, Figure 2b is an enlarged partial cross-sectional view showing a state in which the upper and lower compression member is installed on the body. In FIG. 2A, the upper end of the nut 51 is inserted and fixed to the body 10. A bolt 52 is screwed into this nut 51 and rotated to push the close contact 53 located in the lower part to press the angle piece. Of course, a part of the contact table 53 is inserted into the nut 51, and the contact table 53 linearly reciprocates. In particular, the guide groove 54 is formed in a straight line along the pressing direction in the nut 51 in order to prevent the rotation of the contact table 53 which is different from the rotation of the bolt 52.
이 안내홈(54)을 따라 밀착대가 작동하도록 가이드핀(55)이 안착되며, 이 가이드핀(55)은 밀착대(53)에 고착되어 일체로 운동한다.Guide pins 55 are seated along the guide grooves 54 so as to operate, and the guide pins 55 are fixed to the holders 53 to move integrally.
상하압착부재(40)는 제2b도에 도시된 바와 같이 몸체(10)에 너트(41)하단부가 삽입고정된다. 너트(41)에는 볼트(42)가 나삽되어 밀착대(43)와 연접하고 있다. 볼트(42)가 회전하면 밀착대(43)가 직선이동하여 앵글피스를 압착고정한다. 이때, 밀착대(43)의 회전을 방지하고 직선운동하도록 너트(41)부에는 안내홈(44)이 형성되어 밀착대(43)에 고착된 가이드핀(45)이 안내된다. 특히, 밀착대(43)의 앵글피스 압착부위에는 곡선의 밀착면(46)이 형성되어 당접하는 앵글피스의 주름을 손상시키지 않고 압착지지한다. 아울러, 전술한 몸체의 재질로는 알루미늄이 사용되며, 앵글피스를 압착하는 밀착대는 스텐레스스틸(SUS)로 제작된다.The upper and lower pressing members 40 are fixed to the lower end of the nut 41 in the body 10, as shown in Figure 2b. A bolt 42 is inserted into the nut 41 to be in contact with the contact table 43. When the bolt 42 is rotated, the close contact 43 moves linearly to press-fit the angle piece. At this time, the guide groove 44 is formed in the nut 41 to prevent the rotation of the contact stick 43 and linearly move, and the guide pin 45 fixed to the contact stick 43 is guided. In particular, at the angle piece crimping portion of the contact table 43, a curved contact surface 46 is formed to support the crimp without damaging the wrinkles of the contact angle piece. In addition, aluminum is used as the material of the above-described body, the contact table for pressing the angle piece is made of stainless steel (SUS).
제3도는 본 고안에 다른 용접지그가 맴브레인에 앵글피스를 압착지지하고 있는 상태를 도시한 사시도이다. 여기에 도시된 빗금부분은 용접부위를 나타낸다. 이제, 본 장치의 설치방법은 상세히 설명한다.3 is a perspective view showing a state in which the welding jig is pressed and supported the angle piece to the membrane according to the present invention. The hatched portion shown here represents the weld. Now, the installation method of the apparatus will be described in detail.
먼저, 앵글피스(60)를 화물창의 코너부에 설치되어 있는 맴브레인의 주름에 맞도록 얹어 놓는다. 그리고, 화물창의 맴브레인에 설치된 고정구(70)에 지지대(20)의, 고정판(21)에 형성된 고정홈(22)을 끼워 고정한다. 이때, 고정구(70)로는 주로 스터트볼트가 사용된다. 한편, 이스터트볼트는 단열용 패널 설치용으로 맴브레인에 고착되어 있다. 용접지그의 고정후 앵글피스(60)는 상부에 위치한 상하, 좌우압착부재(40, 50)를 사용해 앵글피스(60)를 스틸코너에 고정한다. 상하,좌우압착부재(40,50)를 사용하여 앵글피스(60)를 고정하기 위해서는 먼저 볼트(42,52)를 회전시킨다. 그러면 볼트(42, 52)는 밀착대(43,53)를 일어 하강시 밀착대(43, 53)는 이와 당접한 안내홈(44, 54)을 따라 이동하는 가이드핀(45,55)과 같이 직선운동하여 앵글피스(60)를 밀어 용접부위가 밀착되도록 한다. 특히, 상하압착부재(40)의 밀착대(43)는 앵글피스(60)의 주름부와 당접하므로 곡선의 밀착면(46)이 형성되어 주름부의 손상을 방지한다.First, the angle piece 60 is placed so as to match the wrinkles of the membrane installed in the corner of the cargo hold. Then, the fixing groove 22 formed in the fixing plate 21 of the support 20 is fixed to the fixing tool 70 provided on the membrane of the cargo hold. At this time, the stud bolt is mainly used as the fixture 70. On the other hand, the ester bolt is fixed to the membrane for the installation of the insulation panel. After fixing the welding jig, the angle piece 60 fixes the angle piece 60 to the steel corner by using the upper, lower, left and right pressing members 40 and 50 located at the top. In order to fix the angle piece 60 by using the upper and lower pressing members 40 and 50, the bolts 42 and 52 are first rotated. Then, the bolts 42 and 52 stand in close contact with the support 43 and 53, and the lower contact 43 and 53 move along the guide grooves 44 and 54 which are in contact with each other. The angle piece 60 is pushed in a linear motion so that the welded portion is in close contact. In particular, the close contact 43 of the vertical compression member 40 abuts the wrinkle portion of the angle piece 60 so that the curved contact surface 46 is formed to prevent damage to the wrinkle portion.
이상에서 설명한 바와 같이, 본 고안에 따른 앵글피스 설치용 용접지그는 용접작업시 지그를 사용하므로 보조자가 불필요하고, 이에 따라 인력의 낭비를 방지할 수 있는 장점을 가지고 있다. 아울러, 일정한 압력으로 용접모재를 연속적으로 눌러 밀착시켜 주므로 용접품질을 향상시킬 수 있는 효과도 가지고 있다.As described above, the welding jig for installing the angle piece according to the present invention uses a jig during the welding operation, so that an assistant is unnecessary, and thus has an advantage of preventing waste of manpower. In addition, it has the effect of improving the welding quality because it continuously presses the welding base material at a constant pressure.
