A method and apparatus for assembling motorcycle frames includes a conveyor defining a path of travel and a pallet movable along the conveyor through a workstation. The pallet supports a rotatable frame for receiving individual components and/or sub-assemblies in fixed relationship with respect to one another in a geometry fixture. The angular position of the rotatable frame and supported geometry fixture can be reoriented about an axis of rotation by engagement with a drive motor. The rotatable frame is normally locked in an angular orientation with respect to the pallet until released by engagement with a lock release actuator or key. The pallet is supported on a movable section of the conveyor, which can be guided between raised and lowered positions with respect to the workstation to accurately and repeatably position the support pallet with respect to the workstation for automated processing operations at the workstation.

Method for assembly of a motorcycle frame

A method and apparatus for assembling motorcycle frames includes a conveyor defining a path of travel and at least one pallet movable along the conveyor through at least one workstation. The pallet supports at least one rotatable frame for receiving individual components and/or sub-assemblies in fixed relationship with respect to one another in a geometry fixture. The angular position of the rotatable frame and supported geometry fixture can be reoriented about an axis of rotation by engagement with a drive motor. The rotatable frame is normally locked in an angular orientation with respect to the pallet. When the movable section of the conveyor and supported pallet are moved, the movable section of the conveyor is guided between raised and lowered positions with respect to the workstation, and the support pallet is accurately and repeatably positioned with respect to the workstation for automated processing operations at the workstation.
