Abstract:
A welding fixture for lying on a base and for holding parts that have upper surfaces that lie in a plane and that are to be pressed down by a head surface of a welding head that moves downward with respect to the base, where said fixture is constructed for adjusting the orientation of the parts about horizontal axes so said upper surfaces can be oriented precisely coplanar with said head surface, comprising:lower and upper fixture assemblies, said lower assembly having a lower surface for resting on said base, and said upper assembly constructed to hold said part, with said upper assembly being pivotable about said horizontal axes on said lower assembly;said upper and lower assemblies having substantially spherical mating surfaces that lie one on the other;at least one fastener that extends between said lower and upper assemblies and that can be tightened to clamp said substantially spherical surfaces together by pressing them firmly against each other.
