Leak test and assembly system for cylinder heads

High flexibility for workpieces and assembly parts

Over an area of approx. 14.5 x 15.5 m (length x width), the high pressure oil chamber of cylinder heads is leak tested in a station with flexibility for several workpiece types.

In the further course of operations, two redundant flexible assembly cells are used, each with 16 and/or 24 valve guides pressed in at room temperature and nitrogen-cooled valve seat rings. An oiling robot in each cell lubricates the base bore holes for the valves at the machine infeed before another robot removes the cylinder head by picking the zero point clamp and places it in the assembly cell.

According to customer requirements there is the possibility of a position adjustment between the press-in units. The number of press-in units can be adapted to the cycle time requirement.

Up to 12 different valve seat rings can be fed in fully automatically by a flexible feed cell and are reliably checked for type and orientation before assembly. Eddy current testing for material recognition is also available as an option. Optionally, different valve guides can be in feed automatically in an oriented manner by feed units.
