Double-head servo robot welding torch device and switching method thereof

The invention discloses a double-head servo robot welding torch device and a switching method thereof. The double-head servo robot welding torch device comprises a machine frame assembly, welding torch assemblies, a circuit system and a switching system, wherein each of the welding torch assemblies comprises a welding electrode and a servo motor; the servo motors are used for controlling the welding electrodes to separately perform independent operation; the two welding electrodes are interchangeably loaded on the machine frame assembly; the circuit system is divided into two circuits which separately communicate with the servo motors of the two welding torch assemblies; and the switching system is used for switching the two circuits and further switching control programs of the servo motors. The double-head servo robot welding torch device is provided with the two independent servo motors and welding torch heads which can be controlled independently and switched at any time for welding. 本发明公开了一种双头伺服机器人焊枪装置及其
