There will be discussed clockwork inspired models for QCD axions or cosmological Goldstone bosons. In those models the
global symmetry is highly protected by gauge symmetries, as it is an accidental symmetry obtained from an abelian quiver
with scalar bifundamental fields. The explictly breaking contributions such as the gravity corrections are strongly suppressed.
The model can be obtained by latticizing an abelian 5d gauge theory on the linear dilaton background.
