H-shaped beam longitudinal joint automatic welding machine and welding machine head

Abstract

The invention discloses an H-shaped beam longitudinal joint automatic welding machine and a welding machine head. The welding machine head comprises an installation frame, wherein a sleeve is arrangedat one end of the installation frame, a vertical shaft is installed in the sleeve in a matched mode, and an installation plate is fixedly connected to the upper end, extending out of the sleeve, of the vertical shaft. The H-shaped beam longitudinal joint automatic welding machine and the welding machine head have the beneficial effects that a weldment clamping device and an angle adjusting devicewhich can rotate synchronously are installed on the vertical shaft of the welding machine head, and the weldment clamping device can rotate along with the shape of a weld joint while clamping and positioning a weldment, so that a welding gun on the angle adjusting device is synchronously adjusted along with the shape of the weld joint, normal welding operation is guaranteed on the premise of nothalting, welding efficiency is improved, and overall welding quality is greatly improved. A rotary encoder on the welding machine head can also detect a bending angle of the weld joint in the weldingoperation process, and if the bending angle is too large, the advancing speed of the welding machine head can be reduced, so that the quality of the welding machine is further ensured.

Description

technical field [0001] The invention relates to the technical field of welding machines, in particular to an automatic H-beam longitudinal seam welding machine and a welding head. Background technique [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 and brings great trouble to production.
