Problems solved by technology

However, this device uses multiple rollers to fix the circular workpiece, so the stability is not high, and the rolling wheel needs to be set separately. After changing the welding position every time, the position of the rolling wheel needs to be adjusted, which is very inconvenient and the user low experience

Abstract

The invention belongs to the technical field of pipe welding, and particularly relates to a device for rotary rolling welding of circular tubes. The device comprises a bottom plate, two reduction motors, two clamping mechanisms, a welding gun and a rolling wheel mechanism. The two reduction motors are symmetrically and slidably installed on the bottom plate, and the distance between the two reduction motors is adjusted by sliding the two reduction motors; the two clamping mechanism are symmetrically installed on the two reduction motors, the reduction motors can drive the clamping mechanisms to rotate, and the two clamping mechanisms are used for clamping the two circular tubes which need to be welded, so that connection of the two circular tubes is achieved. The rolling wheel mechanism comprises a clamping sleeve, two swing rods, a rolling wheel and two elastic pieces, wherein the clamping sleeve is rotationally installed between the ends of the two circular tubes and used for clamping the welding gun, the rolling wheel is rotationally installed between the other ends of the two swing rods, one end of the two elastic pieces is fixedly connected with the clamping sleeve, and the other ends of the two elastic pieces are fixedly connected with the corresponding swing rods. When the circular tubes are welded by using the device, the coaxiality, the same rotating speed and the stability can be ensured, and rolling can be conducted while welding is conducted.

Description

technical field [0001] The invention belongs to the technical field of pipe fitting welding, and in particular relates to a device for rotary rolling welding of circular pipes. Background technique [0002] Butt welding of round pipes has always been a difficult problem in the field of welding because of the rolling properties of the round pipes and the coaxiality of the two round pipes. In engineering, two rollers are usually used to support the round pipe, and then the round pipe is manually rolled for welding. The circular tubes welded in this way cannot accurately control the rotation speed of the circular tubes and the coaxiality of the two circular tubes, resulting in large welding deformation and poor welding quality, especially in some environments that require welding in a vacuum environment, such as Vacuum electron beam welding cannot manually control the rotation of the round tube. At the same time, rolling along with welding can optimize the weld, reduce weldin...
