Abstract

The present invention relates to a link structure for an automatic welding machine according to a curved plate member, and more specifically, to a link structure for an automatic welding machine according to a curved plate member, which can increase welding speeds due to rapid rotation when a welding torch reaches a curved portion of a curved plate member, and which is low in poor welding since rotational inertia is lower due to a bundle of light welding torches having a short movement distance. According to the link structure for an automatic welding machine, the bundle of welding torches is light since weight of supply lines of the welding torches is diffused by a cable stand, so a welding speed gets rapid since rotational speed of the bundle of the welding torches becomes higher when the curved portion is moved. When the bundle of the welding torches rotates from the curved portion, a distance that the welding torches are separated laterally at the center of a main body is as short as upper and lower links. Since a front rotor is conveyed vertically, a load is applied less to the motor so as to increase operation speeds and provide excellent durability.

지티티(GTT)사의 설계도에 따라서 제조되는 엘인지(LNG)선에 설치되는 LNG탱크의 내부에는 급격한 온도변화에 따른 환경에 적합하도록 주름판재를 형성하여 벽면의 수축 및 이완에 대응하도록 하고 있다.Inside the LNG tank installed on the LNG line manufactured according to the GTT company's design, a corrugated plate is formed so as to cope with shrinkage and relaxation of the wall surface so as to be suitable for the environment due to a rapid temperature change.

상기 LNG탱크의 내부를 구성하기 위해서는 주름을 형성한 다수개의 주름판재를 서로 연결하여 연결부를 용접하여 일체로 형성한다.In order to construct the inside of the LNG tank, a plurality of corrugated plate members formed with corrugations are connected to each other, and the connection portions are welded to form an integral body.

상기 주름판재와 주름판재를 자동으로 용접하는 장치에 대한 개발은 일본국 특허청에 특허출원되어 공개된 특개소50-80942호, 대한민국 특허청 등록실용신안공보 제0445017호, 등록특허공보 제732311호 등에 개시된 바 있다.Development of a device for automatically welding the corrugated plate and the corrugated plate is disclosed in Japanese Patent Application Laid-Open No. 50-80942, Japanese Utility Model Registration Utility Registration No. 0445017, Patent Registration No. 732311 There is a bar.

종래의 주름판재를 자동용접하기 위한 용접장치는 도 5와 같이 레일(1)을 따라서 이동할 수 있는 본체(10)와; 상기 본체(10)의 전방에 부착되고, 이동방향에 따라 전후, 좌우로 이송됨과 동시에 주름부분에서 회동하면서 용접할 수 있는 용접토오치부(20)로 구성된다.A conventional welding apparatus for automatically welding a corrugated plate includes a main body 10 capable of moving along the rail 1 as shown in Fig. 5; And a welding torque portion 20 which is attached to the front of the main body 10 and is transported back and forth, left and right according to the moving direction, and can be welded while rotating at the corrugated portion.

또한, 상기 용접토오치부(20)는 본체(10)의 전방에 형성된 볼스크류(22)와 수평가이드(22a)를 따라 이송가능한 작동몸체(21)가 형성되고, 상기 작동몸체(21)의 상단과 틸팅구(24)의 틸팅상부몸체(24a)와 연결되는 로테이션링크(23)가 형성되며, 상기 틸팅구(24)의 하부에 부착된 틸팅하부몸체(24b)의 가운데에서 회전가능하도록 형성되는 토오치(25)로 구성된다.The welding torch portion 20 is formed with a ball screw 22 formed in front of the main body 10 and an operating body 21 capable of being transported along the horizontal guide 22a, And a rotation link 23 connected to the tilting upper body 24a of the tilting opening 24 and formed to be rotatable in the middle of a tilting lower body 24b attached to the lower portion of the tilting opening 24 And a soil 25.

그러나, 종래의 주름판재를 자동용접하기 위한 용접장치는 다음과 같은 문제점이 있었다.However, the conventional welding apparatus for automatically welding the corrugated plate has the following problems.

(1) 용접토오치부의 토오치에 직접 여러가지 공급선들이 부착되기 때문에 용접토오치뭉치가 무거워서 이동이 곡면부에서 용접토오치부의 용접토오치뭉치의 회전이 느리기 때문에 전체적인 용접속도가 떨어진다. (1) Since the welding wire is directly attached to the welding wire, the welding speed is low because the welding wire bundle is heavy and the movement of the welding wire bundle in the welding wire portion is slow in the curved portion.

(2) 곡면부에서 용접토오치뭉치가 회전할 때 본체의 중앙에서 좌우로 이탈되는 거리가 길어서 용접토오치뭉치의 무게로 인해서 모터에 과부하게 걸리게 되고, 운용속도도 현저하게 떨어지게 된다.(2) When the welding torch bundle is rotated at the curved surface portion, the distance from the center of the torso to the right and left is long, so that the weight of the welding torch bundle is excessively caught by the motor and the operating speed is remarkably decreased.

상기한 문제점을 해결하기 위해서, 본 발명은 레일을 따라 이송가능한 레일이송부가 형성되는 상단에 본체가 형성되고, 상기 본체의 전방 가운데에 고정되되,In order to solve the above-described problems, the present invention is characterized in that a main body is formed on an upper end where a rail conveying unit capable of being conveyed along a rail is formed,

상기 본체의 전방 가운데에 고정되는 모터가 형성되고, 내부의 상하에 동일간격으로 이격되어 모터에 연결된 기어에 각각 연결되는 상부기어와 하부기어가 형성되는 커플회전몸체가 형성되며,And a coupling rotating body having an upper gear and a lower gear connected to the gears connected to the motor, the upper gear and the lower gear being formed at upper and lower portions of the main body,

상기 커플회전몸체의 전방 상,하단에 상부기어와 하부기어와 함께 회전하도록 하단 끝단이 각각 연결되는 상부링크와 하부링크가 각각 형성되고, An upper link and a lower link are formed at the upper and lower ends of the coupling rotating body, respectively, and the lower end and the lower link are connected to rotate together with the upper gear and the lower gear,

상기 각 상부링크와 하부링크의 상단 끝단이 상부에 각각 연결되며, 내부에 벨트에 의해서 동일하게 회전하도록 상부풀리와 하부풀리가 각각 형성되는 전방회전체로 구성되는 회정링크부와;And a front rotating body having upper and lower pulleys connected to upper ends of the upper and lower links, respectively, so that the upper and lower pulleys rotate in the same manner by a belt;

상기 회전링크부의 전방회전체의 하부풀리의 전방에 후방하부가 고정되고, 상단에 케이블대가 고정되는 회전지지몸체가 형성되며,A rotary support body is fixed to a front lower portion of a lower pulley of a front rotary body of the rotary link portion,

상기 회전지지몸체의 전방 하단에는 다수개의 센서가 형성되는 센서고정구와 용접토오치가 각각 고정되는 용접토오치뭉치로 구성되는 것을 특징으로 한다.And a welding torch bundle in which a plurality of sensors are formed and a welding torch is fixed to the front lower end of the rotary support body.

본 발명의 곡판부재 대응형 자동용접장치용 링크구조체에 의하면 다음과 같은 효과가 발생한다.According to the link structure for a curved plate member-type automatic welding apparatus of the present invention, the following effects occur.

(1) 용접토오치뭉치의 공급선들을 케이블대에 의해서 무게가 분산되기 때문에 용접토오치뭉치의 무게 가벼워서 곡면부 이동시 용접토오치뭉치의 회전속도를 높힐 수 있어서 용접속도가 빨라진다. (1) Since the weight of the welding wire bundle is distributed by the cable bundle, the weight of the welding wire bundle is light, so that the rotating speed of the welding wire bundle can be increased during the movement of the curved surface portion, thereby increasing the welding speed.

(2) 곡면부에서 용접토오치뭉치가 회전할 때 본체의 중앙에서 좌우로 이탈되는 거리가 상,하부링크만큼 짧고, 전방회전체가 수직으로 이송되므로 모터에 부하가 적게 걸려서 운용속도를 증가시킬 수 있고 내구성이 뛰어나다.(2) When the bundle of welded soil is rotating on the curved surface, the distance deviating left and right from the center of the body is as short as the upper and lower links, and the forward rotating body is vertically fed. Can be durable.

본체(20)의 전방에 링크구조체를 설치하고, 여러가지 공급선을 케이블대(30)를 통해서 연결하여 본체(20)를 레일을 따라 이송시키면서 용접한다. A link structure is provided in front of the main body 20, and various supply lines are connected to each other through the cable band 30, and the main body 20 is welded while being transported along the rails.

주름판재의 평탄한 부분을 용접할 때에는 본체(20)의 정중앙에 수직하게 용접토오치(220)가 위치하고 있다가 센서(210)가 곡면부를 인식하기 시작하면 모터(160)가 작동한다. When the flat portion of the corrugated plate is welded, the welding torch 220 is positioned perpendicular to the center of the main body 20.

도 4를 살펴보면, 전방회전체(110)는 상하로 이송되지만, 상,하부링크(120,122)에 의해서 좌,우로 이송되면서, 회전지지몸체(240)를 회전시키게 된다. 4, the front rotating body 110 is vertically transported, but is rotated by the upper and lower links 120 and 122 to rotate left and right.

이때, 용접토오치뭉치(200)의 전체적인 이동이 중심에서 상부링크(120)와 하부링크(122)의 길이정도만 이동하도록 형성되므로, 그 이동범위가 적어서 용접속도를 높혀도 정확하게 용접가능하게 된다. At this time, since the entire movement of the welding soil bundle 200 is formed so as to move only about the length of the upper link 120 and the lower link 122 at the center, the moving range is small and welding can be accurately performed even if the welding speed is increased.

즉, 용접토오치뭉치(200)가 회전할 때 회전 관성으로 인해서 흔들림이 발생하게 되는데, 본 발명에 의하면 이와 같은 현상이 극히 줄어들게 되어 좋은 용접품질을 얻을 수 있다.That is, when the welded soil batch 200 rotates, shaking occurs due to rotational inertia. According to the present invention, such a phenomenon is extremely reduced and good welding quality can be obtained.

또한, 본 발명의 용접토오치뭉치(200)는 중심에서 약 65도까지 좌우로 기울어지고, 매우 빠른 속도로 회전하더라도 흔들림이 없어서 정확한 용접이 이루어진다.In addition, the welded soil batch 200 of the present invention is tilted to the left and right by about 65 degrees from the center, and even if it rotates at a very high speed, there is no shaking and accurate welding is performed.

본 발명의 곡판부재 대응형 자동용접장치용 링크구조체에 의하면 용접토오치뭉치의 공급선들을 케이블대에 의해서 무게가 분산되기 때문에 용접토오치뭉치의 무게 가벼워서 곡면부 이동시 용접토오치뭉치의 회전속도를 높힐 수 있어서 용접속도가 빨라지고, 곡면부에서 용접토오치뭉치가 회전할 때 본체의 중앙에서 좌우로 이탈되는 거리가 상,하부링크만큼 짧고, 전방회전체가 수직으로 이송되므로 모터에 부하가 적게 걸려서 운용속도를 증가시킬 수 있고 내구성이 뛰어난 등의 효과가 발생한다.According to the link structure for a curved plate member-type automatic welding apparatus of the present invention, since the weight of the supply lines of the welding soil bundle is dispersed by the cable bundle, the weight of the welding soil bundle is light and the rotating speed of the welding soil bundle is increased The welding speed is increased and the distance that the welding torch bundle is rotated from the center of the main body to the left and right is shorter than that of the upper and lower links and the forward rotating body is vertically fed, The speed can be increased and the durability is excellent.

본 발명은 첨부된 도면을 참조하여 바람직한 실시예를 중심으로 기술되었지만 이러한 기재로부터 후술하는 특허청구범위에 의해 포괄되는 본 발명의 범주를 벗어남이 없이 다양한 변형이 가능하다는 것은 명백하다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the scope of the invention as defined by the appended claims.
