Description

맞대기레이저용접용 2차원 유연고정구Butt laser welding 2D flexible fixture

본 발명은 맞대기레이저용접을 하기 위한 판재고정용 장치로서 두 용접선이 이루는 각도와 위치를 조절하여 2개의 용접선을 동시에 고정하여 용접할 수 있는 맞대기레이저용접용 2차원 유연고정구에 관한 것이다.The present invention relates to a two-dimensional flexible fixture for butt laser welding that can be welded by fixing the two welding wires at the same time by adjusting the angle and position of the two welding seams as a device for fixing the butt laser welding.

레이저용접기로 용접을 하기 위해서는 양 판재사이의 용접선이 레이저용접기의 헤드와 일치하고 단차나 틈새가 없도록 용접지그상에서 양 판재를 맞대어 고정시킨 후 용접작업을 한다.To weld with a laser welding machine, weld lines between the two plates match the heads of the laser welding machine and fix them together on the welding jig so that there is no step or gap.

종래의 레이저용접용 지그에서는 판재를 고정시키기 위한 상부고정구가 도1에 도시된 바와 같이 지그상에서의 이동이 불가능한 직선형의 한쌍의 상부고정구(2)로 이루어져 있으며, 사용할 때에는 하부고정구(3)위에 용접용 판재(1,1')를 올려놓고 상부고정구(2)로 압박고정시켜서 사용하였다.In the conventional laser welding jig, the upper fixture for fixing the plate consists of a pair of straight upper fixtures 2, which are not movable on the jig, as shown in Fig. 1, and when used, the upper fixture is welded on the lower fixture 3. The plate (1, 1 ') was put on and used by fixing the pressure to the upper fixture (2).

그러나, 상기의 용접지그에 의하면 상부고정구(2)에 의해 고정되는 판재(1,1')는 용접선(4)이 하나인 직선으로 형성되므로 1차원 직선용접만 가능하다는 문제점이 있으며, 또한 상부고정구(2)는 지그상에서 이동이 불가능하여 용접선(4)이 두 개일 경우 지그상에서 한번에 용접할 수 가 없을 뿐만 아니라, 용접선(4)의 위치가 변경될 경우 지그를 수정할 수 없어서 유연한 용접이 어렵다는 문제점이 있었다.However, according to the welding jig, the plate members 1 and 1 'fixed by the upper fixing tool 2 have a problem that only one-dimensional linear welding is possible because the welding line 4 is formed in a straight line. (2) is not possible to move on the jig, when two welding lines (4) can not be welded at once on the jig, and if the position of the welding line (4) is changed, the jig can not be modified, it is difficult to flexible welding there was.

즉, 승용차의 사이드도어프레임을 용접할 때와 같이 사선용접선과 직선용접선을 함께 구비한 세 개의 판재를 동시에 고정하여 용접할 필요가 있을 때에는 사선의 각도 및 직선의 위치조정이 불가능하여 성형에 유리한 위치로 용접선을 배치시킬 수 없다는 문제점이 있었다.In other words, when it is necessary to fix and weld three plate materials together with a diagonal welding line and a straight welding line at the same time as when welding a side door frame of a passenger car, it is impossible to adjust the angle of the diagonal line and the position of the straight line. There was a problem in that welding lines cannot be arranged.

따라서, 본 발명은 상기 문제점을 해결하기 위하여 이루어진 것으로서, 본 발명의 목적은 용접용 판재의 용접선이 하나일 경우는 물론, 승용차의 사이드도어 프레임을 용접할 때와 같이 사선인 용접선과 직선인 용접선을 함께 구비한 세 개의 판재를 동시에 고정하여 용접할 필요가 있을 때에도 사선의 각도와 함께 직선부의 위치를 임의로 조정하여 성형에 유리한 위치로 용접선의 각도와 위치를 조절할 수 있는 맞대기레이저용접용 2차원 유연고정구를 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is a welding line that is a straight line and a welding line that is a straight line, such as when welding the side door frame of a passenger car, as well as one welding line of the welding plate. Two-dimensional flexible fixture for butt laser welding that can adjust the angle and position of welding line to a position that is advantageous for forming by arbitrarily adjusting the position of the straight line together with the angle of the oblique line even when it is necessary to fix and weld the three plates together. To provide.
