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.The present invention relates to a link structure for an automatic welding device corresponding to a curved plate member, and more specifically, when the welding torch reaches the curved portion of the curved plate member, the rotation speed is fast, the welding speed increases, and the welding torch bundle is light and movable. It relates to a link structure for an automatic welding device corresponding to a curved plate member having a low welding inertia due to a short distance and low rotational inertia.
According to the link structure for the automatic welding device corresponding to the curved member of the present invention, the weight of the welding torch bundle is lightened because the supply lines of the welding torch bundle are distributed by a cable stand, thereby increasing the rotational speed of the welding torch bundle when the curved portion is moved. As the welding speed increases, the distance from the center of the body to the left and right when the welding torch bundle rotates is shorter than the upper and lower links, and the front rotating body is transferred vertically, so the motor is loaded with less load. Effects such as increase in speed and excellent durability occur.

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.The welding apparatus for automatic welding of a conventional corrugated plate includes a main body 10 that can move along the rail 1 as shown in FIG. 5; It is attached to the front of the main body 10, and is composed of a welding torch portion 20 capable of being welded while being rotated in a corrugated portion at the same time as being moved back and forth, left and right according to the moving direction.

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.In addition, the welding torch portion 20 is formed with a ball screw 22 formed in front of the main body 10 and a working body 21 that can be transported along a horizontal guide 22a, and the upper end of the working body 21 And a rotation link 23 connected to the tilting upper body 24a of the tilting sphere 24, and formed to be rotatable in the center of the lower tilting body 24b attached to the lower portion of the tilting sphere 24.

그러나, 종래의 주름판재를 자동용접하기 위한 용접장치는 다음과 같은 문제점이 있었다.However, the conventional welding apparatus for automatically welding corrugated plate material 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 various supply wires are directly attached to the torch of the welding torch, the welding torch bundle is heavy, so the overall welding speed decreases because the movement of the welding torch in the curved portion is slow.

(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 rotates in the curved portion, the distance from the center of the body to the left and right is long, and the weight of the welding torch bundle overloads the motor, and the operating speed drops significantly.

상기 각 상부링크와 하부링크의 상단 끝단이 상부에 각각 연결되며, 내부에 벨트에 의해서 동일하게 회전하도록 상부풀리와 하부풀리가 각각 형성되는 전방회전체로 구성되는 회정링크부와;The upper end of each of the upper link and the lower link are respectively connected to the upper portion, and a revolving link portion composed of a front rotor in which an upper pulley and a lower pulley are respectively formed to rotate equally by a belt therein;

상기 회전링크부의 전방회전체의 하부풀리의 전방에 후방하부가 고정되고, 상단에 케이블대가 고정되는 회전지지몸체가 형성되며,The rear lower portion is fixed to the front of the lower pulley of the front rotating body of the rotating link portion, and a rotating support body is formed to which the cable stand is fixed at the top,

상기 회전지지몸체의 전방 하단에는 다수개의 센서가 형성되는 센서고정구와 용접토오치가 각각 고정되는 용접토오치뭉치로 구성되는 것을 특징으로 한다.It is characterized in that the lower end of the rotating support body is composed of a sensor fastener in which a plurality of sensors are formed and a welding torch bundle in which welding torches are respectively fixed.

본 발명의 곡판부재 대응형 자동용접장치용 링크구조체에 의하면 다음과 같은 효과가 발생한다.According to the link structure for the automatic welding device corresponding to the curved member 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 weights of the welding torch bundles are distributed by a cable stand, the weight of the welding torch bundle is lighter, so that the rotation speed of the welding torch bundle can be increased when the curved portion is moved, thus 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 welding torch bundle rotates on the curved part, the distance from the center of the body to the left and right is shorter than the upper and lower links, and the front rotating body is vertically transported. It can be durable.

이하, 본 발명의 바람직한 실시예로 형성된 곡판부재 대응형 자동용접장치용 링크구조체의 작동을 설명하면 다음과 같다.Hereinafter, the operation of the link structure for the automatic welding device corresponding to the curved plate member formed in the preferred embodiment of the present invention will be described.

본체(20)의 전방에 링크구조체를 설치하고, 여러가지 공급선을 케이블대(30)를 통해서 연결하여 본체(20)를 레일을 따라 이송시키면서 용접한다. A link structure is installed in front of the main body 20, and various supply lines are connected through a cable stand 30 to weld the main body 20 along a rail.

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 welding the flat portion of the corrugated plate, the welding torch 220 is positioned perpendicular to the center of the main body 20 and then the motor 160 operates when the sensor 210 starts to recognize the curved portion.

상기 모터(160)가 회전하면 상부기어(161)와 하부기어(162)가 동일하게 회전하고, 이때, 상부링크(120)와 하부링크(122)가 회전한다. When the motor 160 rotates, the upper gear 161 and the lower gear 162 rotate the same, and at this time, the upper link 120 and the lower link 122 rotate.

상기 전방회전체(110)는 상부링크(120)와 하부링크(122)가 회전하게 되면 회전방향으로 하향하면서 하부링크의 상단에 연결되는 상부풀리가 회전하게 되고 동시에 하부풀리가 회전하면서 동일한 정도로 회전지지몸체(240)가 회전한다.When the upper link 120 and the lower link 122 are rotated, the front rotation body 110 rotates downward to the same degree as the upper pulley connected to the upper end of the lower link rotates while rotating downward. The support body 240 rotates.

도 4를 살펴보면, 전방회전체(110)는 상하로 이송되지만, 상,하부링크(120,122)에 의해서 좌,우로 이송되면서, 회전지지몸체(240)를 회전시키게 된다. Looking at Figure 4, the front rotating body 110 is transferred up and down, while being transferred to the left and right by the upper and lower links (120,122), rotates the rotating support body (240).

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 torch bundle 200 is formed so as to move only about the length of the upper link 120 and the lower link 122 from the center, it is possible to accurately weld even if the welding speed is increased due to a small moving range.

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 welding torch bundle 200 rotates, shaking occurs due to the 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 welding torch bundle 200 of the present invention is inclined to the left and right from the center to about 65 degrees, and even if it rotates at a very high speed, there is no shaking so that accurate welding is achieved.

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 the automatic welding device corresponding to the curved member of the present invention, the weight of the welding torch bundle is lightened because the supply lines of the welding torch bundle are distributed by a cable stand, thereby increasing the rotational speed of the welding torch bundle when the curved portion is moved. As the welding speed increases, the distance from the center of the main body to the left and right when the welding torch bundle rotates is shorter than the upper and lower links, and the front rotating body is transferred vertically, so the motor is loaded with less load. Effects such as increase in speed and excellent durability occur.

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.Although the present invention has been mainly described with reference to the accompanying drawings and preferred embodiments, it is clear that various modifications are possible without departing from the scope of the present invention covered by the claims below.
