AI Technical Summary

Problems solved by technology

[0005] Extremely tight aircraft tolerances complicate the mission
Typically, the end effector weighs 40 to 50 pounds, so the task is further complicated
The task is further complicated by the fact that the manipulator in the confined space must synchronize its task with that of the manipulator outside the wing box

[0058] According to a first embodiment, the manipulator includes an actuator assembly, first and second parallel telescoping lead screw assemblies depending from the actuator assembly, and an end effector coupled to and supported by an end of the lead screw assembly, Wherein the actuator assembly causes each telescoping assembly to independently expand and retract.

[0059]In a first embodiment, each telescoping assembly may include a non-rotatable lead screw and a rotatable lead screw, wherein the non-rotatable lead screw has a tip coupled to an end effector and has an outer threaded end that engages an inner threaded bore of the rotatable lead screw. thread.

[0060] Also in the first embodiment, each telescoping assembly may include first, second and third lead screws, wherein the end of the first lead screw is coupled to the end effector, the first lead screw has a The external threads of the internally threaded hole, the second lead screw has external threads that engage...

Abstract

A robot includes an actuator assembly, first and second parallel telescoping lead screw assemblies cantilevered from the actuator assembly, and an end effector supported by ends of the lead screw assemblies. The actuator assembly causes each lead screw assembly to independently deploy and retract.

Description

Background technique [0001] During aircraft assembly, fastening operations are performed simultaneously on opposite sides of different structures. Fastening operations may include drilling, spot facing, and fastener insertion on one side of the structure such that the end of each inserted fastener terminates on the opposite side of the structure. [0002] Consider fastening operations on aircraft wing boxes. Drilling, spot facing and fastener insertion are performed by a robotic system external to the wing box. Placement of bushings and nuts is performed inside the wing box by manual labor. A person enters the wing box through a small doorway and uses hand tools while lying flat inside the wing box to achieve bushing and nut placement. On the order of hundreds of thousands of fasteners are installed and terminated on general aircraft wings. [0003] It would be highly desirable to eliminate manual labor and fully automate the fastening operation on both sides of the wing b...
