One-sided fastener assembly and methods and systems for installing the same

A method of installing a one-sided fastener assembly into an assembly stack-up, said method comprising:

• partially inserting a core of the one-sided fastener assembly into an opening defined in a sleeve of the one-sided fastener assembly, wherein an inner tapered surface extends from a first end surface of the sleeve and is configured to guide a corresponding outer tapered surface of the core, the outer tapered surface extending from a first end surface of the core to a second end surface of the core;
• locating a position in an assembly stack-up where the one-sided fastener assembly is to be installed;
• drilling hole through the assembly stack-up at the position;
• inserting the sleeve of the partially assembled one-sided fastener assembly into the hole;
• applying an axial force to the core to drive the core into the sleeve opening until an end surface of a head of the sleeve is substantially flush with a front surface of the assembly stack-up and until an end surface of the core is substantially flush with the end surface of the sleeve and the front surface of the assembly stack-up to complete installation of the one-sided fastener assembly.

A fastener installation system for installing a fastener assembly onto an assembly stack-up, said system comprising:

• at least one fastener assembly comprising:
• a sleeve comprising an outer cylindrical surface and an inner tapered surface extending from a first end surface of said sleeve to define an opening extending through said sleeve;
• and
• a core extending along an axis and configured for insertion into the opening, said core comprising a first end surface, an opposing second end surface, and an outer tapered surface extending from said first end surface to said second end surface, said outer tapered surface configured for engagement with said inner tapered surface;
• an end effector configured to insert said at least one fastener assembly into a hole defined in the assembly stack-up;
• a hopper coupled to said end effector, said hopper configured to store a plurality of fastener assemblies;
• and
• a fastener driver coupled to said end effector and configured to apply an axial force to said core to complete installation of said at least one fastener assembly.
