Blind rivet nut-setting tool

A method of operating a blind rivet nut-setting tool, the method comprising:

• pressing a blind rivet nut on an output shaft of the tool against a workpiece, thereby applying an external force to the output shaft to move the output shaft in a rearward direction along a longitudinal axis from a first position to a second position;
• activating a first motor to rotate the output shaft about the longitudinal axis in response to the output shaft activating a limit switch after reaching the second position, thereby rotating the output shaft relative to the blind rivet nut causing plastic deformation of the blind rivet nut;
• activating a second motor to translate the output shaft along the longitudinal axis in the rearward direction, causing further plastic deformation of the blind rivet nut and permanently setting the blind rivet nut on the workpiece;
• depressing a trigger to activate the second motor, causing the second motor and a cam member to rotate about a rotational axis and displace the output shaft along the longitudinal axis to a third position where the blind rivet nut becomes plastically deformed and permanently set on the workpiece;
• and
• depressing a reverse trigger to activate the first motor and rotate the output shaft in an unthreading direction to unthread the blind rivet nut from the output shaft.

• activating the first motor to rotate the output shaft about the longitudinal axis in response to the output shaft reaching the second position, thereby coupling the blind rivet nut onto the output shaft and translating the output shaft toward the first position;
• deactivating the first motor in response to the output shaft returning to the first position, at which point the blind rivet nut is engaged with a nosepiece of the tool;
• and
• activating the second motor to translate the output shaft along the longitudinal axis toward a third position that is rearward of the first position, thereby crushing the blind rivet nut against the nosepiece.
