상기 제2 상부고정구(2)에는 제2 용접용 판재(6)가 판재푸쉬장치(4)에 의해 이동되는 도중 제1 용접용 판재(5)위로 오버랩(overlap)되지 않도록 제2 용접용 판재(6)를 하방으로 가압하는 가압수단(10)이 설치되어 있다.The second upper plate 2 has a second welding plate (6) so that the second welding plate (6) is not overlapped on the first welding plate (5) during the movement by the plate push device (4) ( The pressurizing means 10 which presses 6) downward is provided.
상기 가압수단(10)은 원통형의 본체(11)와, 압축스프링(12)으로 가압된 채 상기 본체(11)에 내장되어 상기 제2 상부고정구(2)하부면(14)에 돌출되도록 설치된 볼베어링(13)과, 제2 용접용 판재(6)의 두께에 따라 상기 본체(11)의 높이를 조정하는 제1 조정나사(15)와, 상기 제1 조정나사(15)로 높이가 조정된 본체(11)를 고정시키는 제2 조정나사(16)를 구비하고 있다.The pressing means 10 is a ball bearing installed to protrude to the lower surface 14 of the second upper fixture 2 is built in the main body 11 while being pressed by the cylindrical body 11, the compression spring 12. (13) and a main body whose height is adjusted by the first adjusting screw 15 and the first adjusting screw 15 to adjust the height of the main body 11 according to the thickness of the second welding plate 6. The 2nd adjustment screw 16 which fixes (11) is provided.
상기 판재푸쉬장치(4)는 제2 용접용 판재(6)를 부착시키는 전자석(17)과, 상기 제2 용접용 판재(6)를 하부고정구(3')상에서 이동시키는 공압실린더(7)를 구비하고 있다.The plate pushing device 4 includes an electromagnet 17 for attaching the second welding plate 6 and a pneumatic cylinder 7 for moving the second welding plate 6 on the lower fixture 3 '. Equipped.
이와 같이 구성되어 있는 본 발명의 일실시예에 의한 맞대기레이저용접용 판재오버랩방지장치의 작용에 대하여 설명한다.The operation of the butt laser welding plate overlap prevention apparatus according to an embodiment of the present invention configured as described above will be described.
먼저, 제1 용접용 판재(5)를 하부고정구(3)상의 기준되는 위치에 정렬시킨 후 제1 상부고정구(1)로 압박하여 고정시킨 다음, 제2 용접용 판재(6)를 하부고정구(3')위에 올려놓고, 제2 상부고정구(2)에 설치된 가압수단(10)이 상기 제2 용접용 판재(6)를 가압할 수 있도록 제1 조정나사(15)로 높이를 적절히 조정한 후 제2 조정나사(16)로 고정시킨다.First, after aligning the first welding plate (5) to the reference position on the lower fixture (3) by pressing the first upper fixture (1) and then fixing the second welding plate (6) lower fixture ( 3 ') and adjust the height with the first adjusting screw 15 so that the pressing means 10 installed on the second upper fixing tool 2 can press the second welding plate 6. Secure with the second adjusting screw (16).
다음에, 상기 제2 용접용 판재(6)를 전자석(20)으로 부착시켜 공압실린더(7)에 의해 제1 용접용 판재(5)와 맞닿을 때 까지 민다.Next, the second welding plate 6 is attached with an electromagnet 20 and pushed until it comes into contact with the first welding plate 5 by the pneumatic cylinder 7.
이 때, 이동되는 제2 용접용 판재(6)는 가압수단(10)의 스프링(12)과 볼베어링(13)에 의해 압박되므로 제1 용접용 판재(5)와 오버랩(overlap)되지 않고 맞닿게 된다.At this time, the second welding plate 6 to be moved is pressed by the spring 12 and the ball bearing 13 of the pressing means 10 to be in contact with the first welding plate 5 without overlapping (overlap). do.
또한, 제2 용접용 판재(6)를 미는 푸셔를 전자석(20)으로 함으로써, 제2 용접용 판재(6)가 강한 힘으로 이동되더라도 제1 용접용 판재(5)와 맞닿으면 제2 용접용 판재(6)와 전자석(20)사이가 미끄러짐으로써 더 이상 판재에 무리한 힘을 주지 않게 되어 양 판재(5,6)의 오버랩(overlap)을 방지한다.Moreover, when the pusher which pushes the 2nd welding board 6 is made into the electromagnet 20, even if the 2nd welding board 6 moves with a strong force, when it contacts with the 1st welding board 5, 2nd welding The slip between the plate 6 and the electromagnet 20 prevents the plate from further exerting force, thereby preventing the overlap of the plates 5 and 6.
상기와 같이 제2 용접용 판재(6)가 제1 용접용 판재(5)와 맞닿도록 정렬되면, 제2 상부고정구(2)가 제2 용접용 판재(6)를 압박고정하게 된다. 상기 제2 상부고정구(2)의 하부면(14)에 돌출된 볼베어링(13)은 스프링(12)의 작용으로 본체(11)내로 함입된다. 따라서, 상기 고정구(2)가 움직여 판재(6)를 압박할 때에도 가압수단(10)의 높이는 변하지 않는다.When the second welding plate 6 is aligned with the first welding plate 5 as described above, the second upper fixing tool 2 press-fixes the second welding plate 6. The ball bearing 13 protruding from the lower surface 14 of the second upper fixture 2 is recessed into the body 11 by the action of the spring 12. Therefore, the height of the pressurizing means 10 does not change even when the fastener 2 moves to press the plate 6.
이와 같이 양 판재(5,6)를 정렬 및 고정시키고 난 후에는 레이저용접기로 양 판재(5,6)사이의 용접선을 따라 용접하는 작업을 수행하게 된다.After aligning and fixing the two plates 5 and 6 as described above, a welding process is performed along the welding line between the two plates 5 and 6 with a laser welding machine.
앞에서 설명한 바와 같이 본 발명의 일실시예인 맞대기레이저용접용 판재오버랩방지장치에 의하면, 맞대기레이저용접을 하기 위하여 용접용 판재들을 정렬할 때 양 판재의 용접부가 상호 오버랩(overlap)됨으로서 발생하는 불필요한 작업중단을 방지하여 연속적인 용접작업을 가능하게 하는 뛰어난 효과가 있다.As described above, according to the butt-laser welding plate overlap prevention apparatus of the present invention, unnecessary work interruption caused by overlapping welding parts of both plates when aligning the welding plates for butt laser welding. There is an excellent effect to enable continuous welding work by preventing the.
