Extraction apparatus

A method of removing a fastener pin from a work piece comprising:

• coupling an actuator device of an extraction apparatus to a power source, the extraction apparatus including an extractor head and an elongated arm that is mechanically coupled to the extractor head, the actuator device mounted on the extractor head, the extractor head defining a channel, the arm including a manual trigger configured to be engaged by an operator;
• positioning the extraction apparatus such that a fastener pin attached to a work piece is received into the channel of the extractor head;
• detecting reception of the fastener pin within the channel via a switch mounted within the channel, the switch operatively connected to the actuator device;
• and
• responsive to the detection of the reception of the fastener pin within the channel occurring concurrently with displacement of the manual trigger, automatically actuating the actuator device to move a fork member of the extractor head within the channel such that the fork member engages and forces the fastener pin away from the work piece.

An extraction apparatus comprising:

• an extractor head defining a channel sized and shaped to receive a fastener pin therein, the extractor head including a pneumatically-actuated slide cylinder that is operatively coupled to a switch disposed within the channel of the extractor head, the switch configured to detect reception of the fastener pin within the channel, the slide cylinder mechanically coupled to a fork member disposed within the channel;
• and
• an elongate barrel having a first end and a second end, the second end mechanically connected to the extractor head, the elongate barrel configured to deliver pressurized air to the slide cylinder on the extractor head, the elongate barrel including a manual trigger that controls delivery of the pressurized air to the slide cylinder,
• wherein, responsive to displacement of the manual trigger occurring concurrently with detection of the reception of the fastener pin within the channel by the switch, the slide cylinder uses the pressurized air to move the fork member within the channel, forcing the fastener pin away from a work piece.
