SYSTEMS FOR IN-PROCESS QUALITY CONTROL DURING DRILL-FILL ASSEMBLY

摘要

A fastener insertion system, for use with an assembly stack-up, includes a fastener and an end effector. The end effector includes a drill bit for drilling a hole through the stack-up, a probe for determining a stack-up parameter, and a fastener feed head for installing the fastener into the hole and applying rotational torque to complete fastener installation. The fastener insertion system also includes a processing device and an angle sensor communicatively coupled to the processing device and to the end effector. The processing device is programmed to measure, with the rotation angle sensor, the angular displacement required to complete fastener installation and to transmit a signal representative of the measured angular displacement from the angle sensor to the processing device. The processing device is also programmed to compare the measurement of angular displacement required to complete fastener installation to a range of angular displacement indicative of correct fastener installation.

1. A fastener insertion system for use with an assembly stack-up, said fastener insertion system comprising:
a one-sided fastener comprising a core bolt and a nut body; an end effector positioned at a location where said one-sided faster is to be installed on the assembly stack-up, said end effector comprising:
a drill bit configured to drill a hole through the assembly stack-up at the location;an automated calibrated probe configured to determine at least one parameter associated with the stack-up proximate the hole; anda fastener feed head configured to install the one-sided fastener into the hole and apply rotational torque to the core bolt to complete installation of the one-sided fastener; a processing device; and rotation angle sensor communicatively coupled to said processing device and to said end effector, said processing device programmed to:
measure, with the rotation angle sensor, an amount of angular displacement required to complete installation of the one-sided fastener after applying the rotational torque to the core bolt;transmit a signal representative of the measured amount of angular displacement from the angle sensor to the processing device; andcompare the measurement of angular displacement required to complete installation of the one-sided fastener to a range of angular displacement indicative of correct installation of the fastener.
