[0001] The invention relates to the technical field of continuous cladding welding torch clamping, in particular to a continuous cladding welding torch clamping device for a bimetallic wire billet. Background Art

[0002] The production method of bimetallic composite wire billets such as copper-clad aluminum or copper-clad steel is mainly the cladding welding method, which uses argon arc welding to weld the longitudinal seam formed by the copper strip wrapped on the core rod.

In this process, the first spring and telescopic column on the adjacent side of the welding torch clamp play an adaptive adjustment role. When the welding torch clamp is close to the welding torch, the first spring is compressed, and the telescopic column shrinks, which can better fit welding torches of different shapes and sizes, firmly clamp the welding torch, and complete the installation and fixation of the welding gun. Then release the push block, and the second spring resets and pushes the push block to slide in the slide slot, thereby pushing the plug column into the corresponding through hole of the knob, limiting the rotation of the knob, preventing the welding torch clamp from loosening due to misoperation, and ensuring the stable clamping of the welding torch during welding.

The second motor is started to rotate the second screw rod, and the second screw rod drives the moving seat to move forward and backward, thereby driving the welding torch below to adjust its forward and backward position, and the third motor can drive the turntable to rotate, so as to adjust the angle of the welding torch below in the horizontal plane to meet the different welding angle requirements of the bimetallic wire billet, and the fourth motor is started to rotate the worm, and the worm is meshed with the worm gear, so that the worm gear and the rotating rod are rotated by the worm, and then the angle of the adjustment plate and the clamp seat is adjusted, and then the welding torch in the clamp seat is adjusted to achieve the adjustment of the angle of the welding torch in the vertical plane, further meeting the requirements of the complex bimetallic wire billet welding process for the welding gun angle.

[0014] The present invention provides a welding gun clamping device for continuous cladding welding of bimetallic wire billets. It has the following beneficial effects:

[0015] 1. The present invention cooperates with each other through the clamp seat, the limit groove, the two-way threaded rod, the knob, the through hole, the welding torch clamp, the first spring, the telescopic column, the support seat, the slide groove, the guide groove, the push block, the second spring, the plug column and the welding torch. The two-way threaded rod is driven to rotate by the knob, and the two-way threaded rod can drive the two welding torch clamps to move relative to each other. In this process, the first spring and the telescopic column on the adjacent side of the welding torch clamp play an adaptive adjustment role. When the welding torch clamp approaches the welding torch, the first spring is compressed and the telescopic column contracts, which can better fit welding torches of different shapes and sizes, firmly clamp the welding torch, and quickly realize the installation and disassembly of the welding gun, improve work efficiency, and cooperate with the limit assembly to limit the rotation of the knob to prevent the welding torch clamp from loosening due to misoperation, and ensure the stable clamping of the welding torch during the welding process.
