Weld joint tracking welding device for U-shaped rib plate

[0012] The specific embodiments of the present invention will be described below in conjunction with the drawings.

[0013] Such as figure 1 , figure 2 As shown, the U-shaped rib welding seam tracking welding device of this embodiment includes a lifting welding arm 1 and a welding gun adjustment device. A sliding shaft 2 is fixed under the lifting welding arm 1, and the lower end of the sliding shaft 2 is connected to an arc guide frame 4 through a guide sleeve 3 , The guide post mounting plate 5 is fixed on the sliding shaft 2, the guide post 6 is installed on both sides of the guide post mounting plate 5, the lower end of the guide post 6 is fixedly connected with the guide post fixing plate 7 connected to the guide sleeve 3, and the outside of the guide post 6 is fixed The spring 8 is compressed, and a guide wheel 41 is installed at the lower end of the arc guide frame 4. The welding gun adjustment device includes a welding torch lifting fine-tuning slide 91, a welding torch lateral fine-tuning slide 92 and a welding gun angle fine-tuning mechanism 93. The welding torch lifting and fine-tuning slide 91 is installed on the side of the arc guide 4 On the upper side, the welding torch horizontal fine-tuning slide 92 is fixed on the welding torch lifting fine-tuning slide 91, the welding torch angle fine-tuning mechanism 93 is fixed on the lower side of the welding torch horizontal fine-tuning slide 92, and the welding torch angle fine-tuning mechanism 93 is fixed with the welding torch 10 with a 30° angle.

[0014] When the U-shaped ribbed seam tracking welding device is used, the lifting welding arm 1 is fixed to the sliding plate through the mounting plate, and can be adjusted left and right and up and down on the sliding plate. The left and right adjustments are floating adjustments, and the U-shaped ribs The plate workpiece is placed on the turning bracket and turned to 30°. The lifting welding arm 1 presses down the arc guide frame 4, and the compression spring 8 compresses to form a certain pressing force on the U-shaped ribbed workpiece. The downward pressure of the arm 1 can achieve different pressing forces on the U-shaped rib workpiece and effectively track it. Then, by adjusting the welding torch lifting fine-tuning slide 91, the welding torch transverse fine-tuning slide 92 and the welding torch angle fine-tuning mechanism 93, the welding wire can be aligned. The quasi-weld groove position is used as an excuse to start welding, and the displacement level is driven by feedback through the guide wheel 41, the arc guide frame 4 slides up and down, and the lifting welding arm 1 is adjusted left and right to realize the tracking welding of the weld.

[0015] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is limited by referring to the claims. The present invention can be modified in any form without departing from the basic structure of the present invention.
