Portable vibratory welding apparatus

摘要

The invention concerns a portable vibratory welding apparatus for welding together metal workpieces which generally are inaccessible for being disposed upon an anvil of a conventional, stationary vibratory welding apparatus. The anvil of the present apparatus is movable and coupled to a support by a leaf spring which provides a bias for causing a gap between the jaw surface of the anvil and a welding tip. Responsive to fluid pressure the anvil is caused to pivot upon a rounded surface disposed between the support and a spacer block of the spring. The pivotal motion of the anvil relative to the support closes the gap between the jaw surface and the welding tip while bowing the leaf spring. After welding is completed and the fluid pressure is released, the force of the leaf spring restores the jaw to its open position.
