Welding device for butt joint of round pipes

Abstract

The invention relates to the technical field of wireless communication equipment, and discloses a welding device for round pipe butt joint, in particular to a clamping mechanism of the welding device, the device comprises a movable base, a sliding guide rail and two sets of round pipe clamps are arranged on the movable base, the movable base is driven by a servo motor and a first lead screw to move, and each round pipe clamp comprises a V-shaped pipe frame, a lifting clamping frame and the like; a first gear and a rack act to drive a second lead screw to rotate, so that a lifting clamping frame descends and is matched with a V-shaped pipe frame with a first rotating roller to clamp a round pipe, a reset spring maintains constant clamping force, and when the round pipe is close to be in butt joint after being clamped and cannot continue to be close to the round pipe, the first lead screw drives related parts to enable the first rotating roller to drive the round pipe to rotate, so that circumferential welding is facilitated; loosening can be prevented, and welding seam alignment and welding quality are guaranteed.
