Part hold down apparatus for part processing machine

摘要

An automatic machine for processing parts comprises at least two part hold down apparatuses, each for releasably holding one of the parts in a predetermined position during processing. The apparatuses are shiftable between an open position for accepting the parts and a closed position for holding the parts for processing. A pneumatic cylinder is operatively conjunctively associated with the apparatuses for providing a conjunctively variable compensating cushioned clamping of the parts for maintaining the parts in the predetermined position during processing. A spring is operatively independently associated with each of the apparatuses for providing an independent variable compensating cushioned clamping of the parts for maintaining the parts in the predetermined position during processing.
