SPOT WELDING PLIERS WITH VARIABLE STEP FOR WELDING ROBOTS.

摘要

Variable pitch spot welding gun device for a welding robot has load dispatching transformers (24,26) that are locked on a mount (16) directly attached to the wrist (12) of an industrial robot used for welding, a stationary spot welding gun (22) formed separately from the transformers (24,26), and a movable spot welding gun (20) made capable of adjusting the pitch distance relative to the stationary gun (22), wherein the stationary and movable spot welding guns (22,20) are connected to the transformers (24,26) through secondary conductors (44a-44c) @(16pp Dwg.No.1/2)@.
