Abstract
Abstract An ultrasonic apparatus for welding or assembling thermoplastic parts is constructed in modular fashion. The apparatus comprises a base having platform adapted to receive a workpiece, a vertical post extending from the base, a first enclosure means containing a power supply, and a second enclosure means containing motive means for an electro-acoustic converter. Both enclosure means, in modular fashion, are connected to each other and supported from the post at an adjustable height from the platform. The base is provided with pushbutton means. The construction shown eliminates the separate power supply and interconnecting cabling. Also, the converter is mounted for quick electrical disconnect and mechanical displacement.
