Knee-lever welding tool for automobile body components has fluid-cooled welding electrodes attached to pivoted clamp arm and cooperating jaw acting as counter-bearing

摘要

The knee-lever welding tool has a clamp head (1) provided with a linear operating drive (2,5), with a piston rod (6) displaced axially relative to the clamp head, cooperating with a knee-lever mechanism (8) at its free end, for pivoting a clamp arm (15) in opposite directions relative a pivot axis (22) in alternation The clamp arm cooperates with a jaw (19) acting as a counter-bearing, each provided with a fluid-cooled welding electrode (17,18), brought together for welding the automobile body component (16) with a high pressure.
