Motoman Robot Arc Welding

Motoman HP50-20 extended-reach robot welds steel and aluminum storage boxes fixtured on two headstock/tailstock positioners.Steel and Aluminum Storage Boxes

Solution meets project goals and objectives for productivity increase and quality improvement. Robotic system provides consistent welds and quality parts. System is capable of welding 81 pre-tacked parts per shift – approximately 25% more than required 65 parts per shift. Pre-tacking fixture and procedures developed to minimize box distortion during welding.

Motoman Robotics provided a modified FabWorld solution, including:

Fixtures/Tooling Details

Motoman Robotics provided two robotic weld fixturing packages for the MHT-450 and MHT-1500 positioners with adjustable locating details and four pneumatically actuated swing-arm clamps designed to accommodate a range of box sizes. Fixtures have hardened details and are mounted on a spanner frame between the headstock/tailstock faceplates. Manual changeover is required between box sizes. Motoman also provided a tacking fixture package. The tacking fixture is manually adjustable to accommodate different box sizes. A main table base is approximately 24" from the floor. Two manual top clamps and four pneumatic clamps are used to locate parts. Manual changeover is required between box types.
