Date Feb. 3, 1994A mounting mechanism for mounting a fastener applicator on a positioning mechanism. The mounting mechanism incorporates fluid actuators for applying compensating forces and turning moments that counteract the effects of the applicator weight by bringing the forces and turning moments into substantial equilibrium or predetermined directional bias so that the applicator is movable by a minimal force. The fluid actuators thereby enabling final correction of the applicator position and orientation prior to fastener application by movement of the fastener applicator relative to the position mechanism as a result of contact between the applicator and the workpiece.</p> |
