An apparatus and method for assembling a fan grill to a shroud of a fan housing. The apparatus includes a support structure having a moveable carriage disposed in a horizontal plane. The moveable carriage is adapted to align and carry the fan grill and shroud combination. A clamping structure is moveably attached to the support structure and has clamps adapted to clamp the fan grill and shroud combination in a fixed position. A plurality of automatic drivers attached to the clamping structure are moveable in a direction transverse to the horizontal plane of the carriage. The automatic drivers drive a plurality of fasteners into the fan grill and shroud combination. The moveable carriage may be adapted to carry more than one fan grill and shroud combination to allow an operator to load a second fan grill and shroud combination onto the carriage while a first fan grill and shroud combination is engaged by the drivers. Each of the automatic drivers are capable of being independently controllable in relation to each other via a control system.

Automated method and apparatus for driving fasteners into an electric fan assembly

A relatively simple and inexpensive apparatus and method for providing high quality and aesthetically pleasing continuous resistance welded hollow metal articles at constant speed comprises an article workpiece conveying guide means for guiding the article workpiece through a welding means under controlled, stable, vibration free conditions in a predetermined path. The path has linear and non-linear portions. A sensor interactively connected to a programmable controller which functions to move the workpiece quickly and accurately through the welding means under stable conditions at a high uniform rate of speed. A first guide provides a weld edge reference guide, and a simple pivotal tracking system provides a weld path guide during non-linear travel of the workpiece. The tracking system exerts its force on the workpiece generally through the center of percussion of the article workpiece whereby no vibration is imparted by the force to the workpiece.
