Abstract

The invention discloses a rotating arc sensor for eutectic pool twin-wire tandem welding, which is applied to the fields of welding automation, robot welding and automatic welding seam tracking. It mainly includes two conductive rods, a driving mechanism, an eccentric adjustment mechanism, a water-air chamber assembly, an upper end cover, a stopper fixing cover, a motor support plate, a middle cavity shell, a lower cavity shell and a signal acquisition device. When the driving mechanism is running, it drives the front conductive rod to make a conical rotary motion, and the trailing conductive rod is fixed and forms a eutectic pool with it. The current signal and the initial position signal are collected by the signal acquisition device and the signal is transmitted to the computer, and the corresponding welding seam tracking action is realized after processing. Compared with the prior art, the present invention has the following advantages and outstanding effects: the present invention can be used in While realizing weld seam tracking, the cladding rate is increased, thereby increasing the welding speed, increasing productivity, and bringing certain benefits to the company.

Description

technical field [0001] The invention relates to the technical field of welding guns, in particular to a welding gun for eutectic pool twin-wire tandem rotary arc welding; it is not only a welding gun with a special structure, but also can be used as a sensor detection device for seam tracking. Background technique [0002] Twin-wire tandem arc MAG / MIG welding is a new type of high-efficiency welding method, which has been widely used in shipbuilding and machinery manufacturing in recent years. Twin-wire tandem arc MAG / MIG welding has a very high welding speed, and manual welding cannot be used. Robots are generally used to program or teach. This method requires a long teaching and preparation process, and it is difficult to overcome errors caused by weld deformation. Therefore, high-speed and accurate seam tracking has become an urgent need for twin-wire tandem arc MAG / MIG welding. During the welding process, real-time detection of welding torch deviation is a prerequisite...
