Patent number: 7165309Abstract: 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.Type: GrantFiled: January 18, 2005Date of Patent: January 23, 2007Assignee: Progressive Tool & Industries Co.Inventors: Velibor Kilabarda, Michael R.
