Support position, to change horn II 2 and horn I 1 subtended angle and sliding sleeve I 4 and sliding sleeve II 5 in horn I 1 and horn
Support Position on II 2, thus when Pneumatic extension cylinder 3 extends, the pressure of II 2 two electrode tips of left end of horn I 1 and horn
Tight angulation change makes electrode tip upon wear still can be to just welding with this；It can be with by adjusting adjusting screw rod II 12
The distance between linkage fasteners 8 and Pneumatic extension cylinder 3 are adjusted, the subtended angle of horn I 1 and horn II 2 is further adjusted, changes
Become two electrode tips to positive-angle；Spring compression can be made in page with the elastic force of adjustment spring by rotating adjusting screw rod II 12
Between plate 8-2 and cylinder jacket attached plate 11-2, when electrode tip abrasion is larger, two electrode tip contacts need to make horn I 1 and electricity
The angle of polar arm II 2 further decreases, at this point, when Pneumatic extension cylinder 3 extends, connecting rod II 6 and connecting rod I 7 are respectively in horn II 2
Linkage fasteners 8 are pushed to be moved to right end under the action of horn I 1, to make spring further compress, horn I 1 and electricity
Two electrode tips of II 2 left end of polar arm are pressed on welded part；The extended length of Pneumatic extension cylinder 3 can be more than conventional point
The telescoping cylinder that weldering soldering turret uses makes linkage fasteners 8 to the right when 3 extended length of Pneumatic extension cylinder is larger by compressed spring
End movement, can be such that electrode tip is pressed on welded part, and will not be because of the excessive burn-through metal plate of pressing force；Pneumatic extension cylinder
3 extended lengths increase, and can enable spot-welding welding tongs that can still electrode tip be made to be filled with welded part after electrode tip abrasion
Tap is touched, it is advantageously ensured that weld strength.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, the art
