Abstract
An automatic welding and annealing machine and specifically a machine for producing unique piston connecting rod assemblies utilized in compressors used in automotive air conditioning systems. The parts produced by this machine are comprised of a rod approximately one-quarter of one inch in diameter and one and three-quarters inch long to which steel balls of approximately one-half inch diameter are welded at each end. These parts are to be used as connecting rods for variable displacement piston pumps. The machine incorporates feeding mechanisms for feeding the separate parts to the welding station and then to the annealing station and also includes a laser inspection apparatus for checking the dimensions of the rods and of the welded and annealed parts, to see that they are within set tolerances. Measuring devices are also provided for monitoring and controlling the electric currents and forces used during welding and annealing of the parts.
