Problems solved by technology

[0002] U-shaped ribs (also known as closed ribs) are a kind of reinforced ribs widely used in the bearing boxes of highways and railway bridges, and the bearing joints of large weighing instruments. The load-bearing requirements are high, and generally all require full For penetration welding, since the rib itself has a certain angle, and a groove of about 40 degrees is also processed, the welding position is very special, and the general conventional welding position cannot meet the requirements. The workpiece is turned to a 30-degree inclined position, and a semi-automatic welding trolley is used f...

Abstract

The invention relates to a U-shaped rib seam tracking welding device, which includes a lifting welding arm and a welding torch adjustment device. A sliding shaft is fixed under the lifting welding arm. The lower end of the sliding shaft is connected to the arc guide frame through a guide sleeve. Fix the guide post mounting plate, guide posts are installed on both sides of the guide post mounting plate, the lower end of the guide post is fixedly connected with the guide post fixing plate connected to the guide sleeve, a compression spring is fixed on the outside of the guide post, and the The guide wheel is installed at the lower end of the arc guide frame, the welding torch adjustment device is fixed on one side of the arc guide frame, the welding torch is fixed on the welding torch adjustment device, the welding seam tracking welding device of the U-shaped rib plate is used, and the lifting welding arm adopts a square guide rail to prevent Impact, strong impact resistance, the arc guide frame is pressed by springs, the pressing force is adjustable, the tracking is sensitive, the guide wheel guide resistance is small, the welding torch is connected through the welding torch adjustment device, and the welding torch can be quickly adjusted. The whole mechanism has no electrical parts. Simple structure and easy maintenance.

Example Embodiment

[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.
