Abstract
A welding gun includes an actuator and welding tips. The actuator includes a stator coupled to a welding robot and a rotor rotatable relative to the stator about an axis of the actuator. The stator includes an axially extending portion and at least one circumferentially extending arm. The rotor includes an axially extending portion and at least one circumferentially extending arm. The welding tips are coupled to an end of the circumferentially extending arm of the stator and an end of the circumferentially extending arm of the rotor. Lengths of the axially extending portion of the stator and the axially extending portion of the rotor can be determined to any length so long as strength and rigidity are assured.
Claims8
A welding gun comprising:
- an actuator having an axis, said actuator including a stator and a rotor rotatable about said axis of said actuator relative to said stator;
- and
- at least one first welding tip supported by said stator and at least one second welding tip supported by said rotor, said first welding tip and said second welding tip being arranged in a circular path having a center on said axis of said actuator, said second welding tip being movable relative to said first welding tip in said circular path.
The welding gun according to clam 1, wherein said welding gun is coupled to a robot so that said stator is driven by said robot to rotate about said axis of said actuator.
