Abstract

Tooling systems and methods may be employed for installing a plurality of visually similar threaded fasteners to a plurality of assemblies. Each of the assemblies may have one or more threaded mating surfaces configured to receive different types of threaded fasteners, e.g., formed of different materials. The tooling system may include a tool(s) having a drive surface configured to install a threaded fastener by relative rotation of a gripping feature of the fastener with respect to a corresponding mating thread, each tool having a sensor disposed adjacent the drive surface and configured to detect a presence of the first material when a gripping feature of the one of the threaded fasteners of the first fastener type is positioned on the drive surface. The tooling system may also include a controller configured to determine the type of the selected threaded fastener based upon the sensor.

First claim

What is claimed is:

1. A tooling system for installing a plurality of visually similar threaded fasteners to a plurality of assemblies, each of the assemblies having one or more threaded mating surfaces configured to receive the threaded fasteners, the plurality of threaded fasteners including a first fastener type formed of a first material, and a second fastener type formed of a second material different from the first material, the tooling system comprising:
one or more tools having a drive surface configured to install a selected threaded fastener by relative rotation of a gripping feature of the selected threaded fastener with respect to corresponding mating threads, each tool having a sensor disposed adjacent the drive surface and configured to detect a presence of the first material when a gripping feature of the one of the threaded fasteners of the first fastener type is positioned on the drive surface; and
a controller in communication with the one or more tools and configured to determine whether the selected threaded fastener is of the first fastener type or the second fastener type based at least upon the sensor.

2. The tooling system of claim 1 , wherein the sensor is one of a magnetic field sensor or a metallic proximity sensor.

3. The tooling system of claim 1 , wherein the tool includes a magnet.

4. The tooling system of claim 1 , wherein the tool is a socket.

5. The tooling system of claim 4 , wherein the socket is configured to receive a head of the threaded fastener, the head of the threaded fastener defining the gripping feature.

6. The tooling system of claim 5 , wherein the tool includes a magnet that is movably disposed within the tool.

7. The tooling system of claim 6 , further comprising a spring biasing the magnet toward a first position, wherein the magnet is configured to slide toward a second position when a fastener of the first fastener type is inserted into the socket.

8. The tooling system of claim 6 , further comprising first and second ring sensors spaced apart in a direction parallel to a sliding direction of the magnet, such that the ring sensors are configured to determine whether the magnet is in a first position or a second position.

9. A tooling system for installing a plurality of visually similar threaded fasteners to a plurality of assemblies, each of the assemblies having one or more threaded mating surfaces configured to receive the threaded fasteners, the plurality of threaded fasteners including a first fastener type formed of a first magnetically susceptible material, and a second fastener type formed of a second material that is not magnetically susceptible, the tooling system comprising:
one or more tools having a drive surface configured to install a selected threaded fastener by relative rotation of a gripping feature of the selected threaded fastener with respect to corresponding mating threads, each tool having a magnet disposed adjacent the drive surface, the tool configured to detect a magnetic force imparted by one of the threaded fasteners of the first fastener type when a gripping feature of the one of the threaded fasteners is positioned on the drive surface; and
a controller in communication with the one or more tools and configured to determine whether the selected threaded fastener is of the first fastener type or the second fastener type based at least upon the magnet.

10. The tooling system of claim 9 , wherein the tool includes a socket configured to receive a head of the threaded fastener, the head of the threaded fastener defining the gripping feature.

11. The tooling system of claim 9 , further comprising a retention ring configured to retain the magnet within the tool.

12. The tooling system of claim 9 , wherein the magnet is movably disposed within the tool.

13. The tooling system of claim 12 , further comprising a spring biasing the magnet toward a first position.

14. The tooling system of claim 13 , wherein the magnet is configured to slide toward a second position when a fastener of the first fastener type is inserted into the socket.

15. The tooling system of claim 9 , further comprising first and second ring sensors spaced apart in a direction parallel to a sliding direction of the magnet, such that the ring sensors are configured to determine whether the magnet is in a first position or a second position.

16. A tool for installing a plurality of visually similar threaded fasteners to a plurality of assemblies, each of the assemblies having one or more threaded mating surfaces configured to receive the threaded fasteners, the plurality of threaded fasteners including a first fastener type formed of a first magnetically susceptible material, and a second fastener type formed of a second material that is not magnetically susceptible, the tool comprising:
a drive surface configured to install a selected threaded fastener by relative rotation of a gripping feature of the selected threaded fastener with respect to corresponding mating threads; and
a magnet disposed adjacent the drive surface and configured to detect a magnetic force imparted by one of the threaded fasteners of the first fastener type when a gripping feature of the one of the threaded fasteners is positioned on the drive surface.

17. The tool of claim 16 , wherein the tool includes a socket configured to receive a head of the threaded fastener, the head of the threaded fastener defining the gripping feature.

18. The tool of claim 16 , wherein the magnet is movably disposed within the tool.

19. The tool of claim 18 , further comprising a spring biasing the magnet toward a first position, wherein the magnet is configured to slide toward a second position when a fastener of the first fastener type is inserted into the socket.

20. The tool of claim 16 , further comprising first and second ring sensors spaced apart in a direction parallel to a sliding direction of the magnet, such that the ring sensors are configured to determine whether the magnet is in a first position or a second position.
