Description

교량용 박스 생산라인 중에 박스의 코너용 용접장치Corner welding machine for box in bridge box production line

일반적으로 교량용 대형박스를 생산하는 공정중에 마무리 되는 코너 용접은 좌, 우측판과 상, 하측판이 만나는 테두리를 용접하는 것으로서 그 용접부분을 종래에는 용접기로 사람이 직접 용접 하였다.In general, the corner welding, which is finished during the process of producing a large box for bridges, is to weld the edge where the left, right and upper and lower plates meet. The welding part is conventionally welded directly by a welder.

그러나 이와 같은 용접방법은 정확한 용접 보다는 불규칙적으로 용접 가능성이 높아 틈새가 많으며, 용접부외가 이완되는 결점이 있고 특히 용접 이후에도 눈으로 확인하여야 하는 불편한 점이 있으며, 또한 자동화 생산라인이 않이기 때문에 대량생산을 할수 없는 문제점이 있는 것이다.However, this welding method has many gaps due to the possibility of welding irregularly rather than accurate welding, and there is a flaw that the welding part is relaxed, and in particular, it is inconvenient to check visually after welding, and also because it is not an automated production line, mass production can be performed. There is no problem.

The guide bars 117 and 117 'are installed in the longitudinal direction, and the driving roller 119 is fitted to the guide form 118 formed in the guide bar, and the driving rollers are coupled to both sides of the slide flange 120 by the driving shaft. The shaft 122 of the DC motor 121 is fitted by drilling a hole in one side of the slide flange, and the spur gear 123 is installed at the end of the shaft and the rack gear 124 engaged with the spur gear is the guide block 116. It is formed on one side of the front and can move the guide block up and down. A plurality of guide bars 125 for guiding at the time is formed in the center frame 126 formed at the rear, the DC motor 127 is installed on one side of the lower frame 114, the shaft 128 of the DC motor The timing belt 129 is fastened to the built-in timing pulley 129, and the timing belt is fastened to the timing pulley 131 built at the end of the drive shaft 130 at the lower side of the lower frame. 132 is built up, one side of the slide flange 120 is configured to be attached to the welder 133 that can weld the corner portion of the pipe.

도면중 미설명 부호 134는 레일이다.In the figure, reference numeral 134 denotes a rail.

상기와 같이 구성된 본 고안의 작용은 내부용접이 완료된 박슬를 체인컨베이어로 이송하여 코너용접본체(100)에 위치하면 레일(134)상에 후진된 코너용본체가 코너용접을 하기 위해 전진하는 것이다. 즉, 하부프레임(114)의 상측에 고정된 직류모타(127)가 구동하면 타이밍벨트(129)가 회전하고 이어 타이밍풀리(131)를 구동시키는 것이다. 따라서 타이밍풀리를 축설한 구동축(130)이 구동하고 구동축 양측에 결착된 구동바퀴(132)는 레일상에서 전방으로 진행하는 것이다.The operation of the present invention configured as described above is to transfer the thinner completed the internal welding to the chain conveyor is located in the corner welding main body 100 is to move forward for the corner welding the corner body back on the rail 134. That is, when the DC motor 127 fixed on the upper side of the lower frame 114 is driven, the timing belt 129 rotates and then drives the timing pulley 131. Therefore, the drive shaft 130, which has a timing pulley installed thereon, is driven and the drive wheels 132 bound to both sides of the drive shaft move forward on the rail.

이어서 상부프레임(101)에 설치된 기어드보타(111)를 구동시키면 수직스크류(113)가 회전하면서 상승된 가이드블럭(116)을 하강시킴과 동시에 상승된 슬라이드 플랜지(120)가 하강하는 것이다. 이때 가이드블럭(116)은 후방의 가이드바(125)가 안내하는 것이다.Subsequently, when the geared bow 111 installed in the upper frame 101 is driven, the vertical flange 113 rotates while the raised guide block 116 is lowered, and at the same time, the elevated slide flange 120 is lowered. At this time, the guide block 116 is guided by the guide bar 125 at the rear.

이와 같이 가이드블럭(116)과 슬라이드플랜지(120)가 하강하여 일정한 높이에서 정지하면 슬라이드플랜지(120)의 전방일측에 형성된 용접기(133)가 박스의 코너 부분을 용접하게 되며, 이때 부터 슬라이드플랜지(120)의 전방 일측에 형성된 직류모타(121)가 구동하여 평기어(123)를 구동시키면 평기어(123)와 치합된 랙기어(124)는 가이드블럭(116)에 의해 고정되어 있어 결국 직류모타(121)가 설치된 슬라이드플랜지(120)가 좌에서 우로 또는 우에서 좌로 이동하게되는 것이다.As such, when the guide block 116 and the slide flange 120 are lowered and stopped at a predetermined height, the welder 133 formed at one front side of the slide flange 120 welds a corner portion of the box. When the direct current motor 121 formed on one side of the 120 is driven to drive the spur gear 123, the rack gear 124 engaged with the spur gear 123 is fixed by the guide block 116. Slide flange 120 is installed is to move from left to right or from right to left.

이상에서 설명한 바와 같이 본 발명은 박스의 내부용접이 완료되어 체인컨베이어로 이송하면 코너용접본체가 전진하고 일측에 성형된 토치가 코너부분을 자동으로 이동하면서 용접하는 것으로서, 정확한 용접으로 용접부분에 틈새가 없으며, 용접부위가 이완되는 결점이 없고 특히 자동화 생산라인으로 대량생산을 할수 있는 효과가 있다.As described above, in the present invention, when the inner welding of the box is completed and transferred to the chain conveyor, the corner welding main body moves forward and the torch formed on one side is welded while automatically moving the corner portion. There is no flaw that the welding part is relaxed, and in particular, there is an effect that can be mass-produced by automated production line.

본 발명은 교량용 대형박스를 생산하는 것으로서, 특히 장방형의 박스에 마무리 공정인 외측 코너부분을 용접하는 장치에 관한 것이다.The present invention relates to the production of large boxes for bridges, and more particularly to an apparatus for welding an outer corner part which is a finishing process to a rectangular box.
