Self-piercing rivet installation apparatus

Abstract

A self-piercing rivet installation apparatus includes a rigid C-frame and a drive spindle translatable along a rivet installation axis through a first jaw of the rigid C-frame. An installation head has an installation head mounting end mountable to a leading end of the drive spindle. A mounting post having a mounting post root end is matingly engaged with a jaw socket defined coaxially with the rivet installation axis in a second jaw of the rigid C-frame. A coupling tube has a coupling tube mounting end. A riveting anvil is removably mounted to the coupling tube to form an anvil mounting assembly. The anvil mounting assembly is alternatively mountable on the drive spindle and the mounting post. The installation head is alternatively mountable on the mounting post and the drive spindle opposite the anvil mounting assembly.
