Abstract
A chuck device capable of efficiently changing a welding tip and nozzle. The chuck device includes a rotatable chuck base, an engagement part fixed to the chuck base so as to rotate integrally with the chuck base and can engage an engagement surface of the welding tip, the engagement part allowing the welding tip to rotate with the chuck base when the chuck base is rotated while engaged with the engagement surface, and a plurality of fingers provided to the chuck base to be openable and closable and can hold the welding tip and the nozzle, the plurality of fingers being capable of moving in directions approaching and separating from the engagement part.
Claims8
A chuck device for changing a welding tip and a nozzle surrounding the welding tip, the welding tip being screwed into a welding torch main body, the chuck device comprising:
- a chuck base rotatably provided;
- an engagement part fixed to the chuck base so as to rotate integrally with the chuck base, and able to engage an engagement surface formed at an outer circumferential surface of the welding tip, the engagement part rotating the welding tip together with the chuck base when the engagement part engages the engagement surface and the chuck base is rotated;
- and
- a plurality of fingers provided at the chuck base so as to be able to open and close, the plurality of fingers being able to move in directions approaching and separating away from the engagement part and grip each of the welding tip and the nozzle, the plurality of fingers moving in the direction approaching the engagement part so as to be brought into a closed state and moving in the direction separating away from the engagement part so as to be brought into an open state.
