Motoman Robot Arc Welding

Steel and Aluminum Storage Boxes

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

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 Solution

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.
