Abstract:
1. A cap tip detaching apparatus for a welding machine for detaching a cap tip fitted to a leading end portion of a shank of the welding machine, the apparatus comprising: a base; a guide plate mounted on the base defining an insertion location capable of receiving the shank with an axis of the shank coincident with an axial direction of the insertion location; a movable pawl coupled together with a fixed pawl such that the movable pawl is capable of being brought into close contact with an upper end portion of the cap tip; a rotating mechanism for rotating a lever extending to a rear side of the movable pawl, thereby pushing the movable pawl away from the fixed pawl, the rotating mechanism comprising a slide truck mounted to the base and freely movable in an orthogonal direction with respect to the axial direction of the insertion location; and a fixed pawl unit attached to a leading end of a rod elastically supported on the slide truck in such a manner as to always protrude to a front-side of the slide truck, the fixed pawl being provided in the fixed pawl unit and the fixed pawl being movable in relation to the base and in the orthogonal direction such that the fixed pawl is capable of being brought into close contact with a lower end portion of the shank; wherein the slide truck comprises a cam groove for actuating the rotating mechanism on the basis of further movement of the slide truck in the orthogonal direction after a movement of the fixed pawl to a location between the shank and the cap tip.
