H-beam longitudinal seam automatic welding machine and welding head

Abstract

The H-beam longitudinal seam automatic welding machine and the welding head include an installation frame, one end of the installation frame is provided with a sleeve, a vertical shaft is installed in the sleeve, and an installation plate is fixedly connected to the upper end of the vertical shaft extending out of the sleeve. The positive effect of the present invention is that in the H-shaped beam longitudinal seam automatic welding machine and the welding head according to the present invention, a welding piece clamping device and an angle adjusting device that can rotate synchronously are installed on the vertical shaft of the welding head, and the welding The workpiece clamping device can rotate along with the shape of the welding seam while clamping the positioning weldment, so that the welding torch on the angle adjustment device can be adjusted synchronously with the shape of the welding seam, so as to ensure the normal progress of the welding operation without stopping. It not only improves the welding efficiency, but also greatly improves the overall welding quality. The rotary encoder on the welding head can also detect the bending angle of the welding seam during the welding operation. If the bending angle is too large, the traveling speed of the welding head can be reduced to further ensure the quality of the welding machine.

Description

technical field [0001] The invention relates to the technical field of welding machines, in particular to an H-shaped beam longitudinal seam automatic welding machine and a welding head. Background technique [0002] Existing longitudinal seam welding machines can perform high-quality welding of welds with regular straight shapes, but for gooseneck beams or other irregular weldments, the position of the bent weld usually requires stopping to adjust the angle of the welding torch, or Directly by manual welding, if it is manual welding, the welding of irregular welds is generally more difficult, and the labor intensity is significantly increased. If the welding torch position is adjusted continuously, the welding efficiency of the welding machine will also be reduced, and the operation of adjusting the welding torch position back and forth It often leads to inconsistent overall welding quality, which brings great trouble to production. SUMMARY OF THE INVENTION [0003] In o...

[0002] Existing longitudinal seam welding machines can perform high-quality welding for welds with regular straight shapes, but for gooseneck beams or other irregular weldments, the position of the bent weld usually needs to be stopped to adjust the angle of the welding torch, or Direct manual welding, if it is manual welding, the difficulty of welding irregular welds is generally greater, and the labor intensity is significantly increased. If the machine is continuously shut down to adjust the position of the welding torch, the welding efficiency of the welding machine will also be reduced, and the operation of adjusting the position of the welding torch It often leads to inconsistent overall welding quality, which brings great trouble to production
