ABSTRACT:
An apparatus for assembling a bicycle frame of the type in which the head tube, bottom bracket and seat post bracket include stubs for receiving connecting tubes in a press fit. The apparatus includes a base, a clamp for receiving the bottom bracket, a carriage for receiving the head tube, and a swing arm which pivots about the axis of the bottom bracket clamp and receives the seat post bracket and seat mast of the bicycle frame. Double-acting cylinder motors are mounted on the base for displacing the carriage toward the bottom bracket clamp and for pivoting the swing arm toward the carriage. Other cylinder motors are mounted on the carriage and are actuated to secure the head tube, and a cylinder motor is mounted on the swing arm to urge the seat bracket toward the bottom bracket. A computer control selectively actuates the cylinders to urge the bottom bracket, seat post bracket, and head tube toward each other in a substantially continuous motion, thereby urging their respective stubs into the ends of the connecting tubes to form the bicycle frame.
