Assembly of Pinions

Need


Complex Assembly Equipment

Assembly of central gearboxes for trucks with very few operators. 13 product families with a vast number of configurations. The equipment needs to be built on a very small footprint. It requires precise inline measurement to enable shim selection.

Solution


Highly Automated Assembly Line on a Small Footprint

  • Robotic assembly of housings, bearings, and pinions.
  • Electric servo presses, up to 20 tons.
  • Automatic tool changers in presses for upper and lower punches.
  • Automatic screwdriving station.
  • Inline measurement of bearings with a coordinate measuring machine, Hexagon.
  • Inline measurement of housings with a coordinate measuring machine, Hexagon.
  • Special measuring machine for pinions, Sylvac.
  • Special measuring machine for bearings under pressure.
  • Shim measurement.
  • 2 ABB robots for product handling.
  • 2 UR robots for bearing handling.
  • 1 Epson SCARA robot for product pallet setting.
  • 1 handling portal for pinions.
  • Conveyor system with product-adapted pallets.
  • Automatic greasing.
  • Automatic Loctite handling.
