6. The device according to the claim 1 , wherein the guide bar extends along a length of the structural beam and laterally thereto so as to enable a movement of the tool holder along the structural beam along a length of edges of the panels to be joined.
7. The device according to claim 1 , wherein the tool holder comprises a deflectometer to control an operation performed by the tool mounted in the said tool holder.
8. The device according to claim 1 , wherein the tool comprises a machining tool or a stripping tool mounted on the tool holder of the at least one anvil rail.
9. The device according to claim 1 , wherein a movable support comprises pins to engage with holes of at least one first panel and at least one second panel of the plurality of panels.
10. A system for assembling a plurality of panels of an aircraft fuselage, the plurality of panels comprising at least one first panel and at least one second panel, the system comprising:
at least one anvil body comprising a support surface supporting the plurality of panels;
at least one anvil rail movably mounted in a cavity of the at least one anvil body and moving between:
a top position, in which an upper surface of the at least one anvil rail extends into an extension of the support surface to form a counter-support for a first face of the at least one first panel and a second face of the at least one second panel during friction stir welding, and
a bottom position, in which a workspace is created between the upper surface of the at least one anvil rail and the support surface so as to enable a passage of a stripping or machining tool,
wherein the at least one anvil rail further comprises:
a structural beam,
a tool holder comprising the stripping or machining tool, and
a guide bar,
wherein the structural beam extends along an entire length of the at least one anvil body, and
wherein the guide bar is sized and shaped to guide the tool holder in the cavity; and
a mover mounted on the at least one anvil body,
wherein the mover is arranged to move the at least one first panel in relation to the at least one second panel between:
a first machining position, wherein an edge of the at least one first panel and an edge of the at least one second panel are spaced a machining distance apart to allow the stripping or machining tool to pass between the edges of the at least one first panel and the at least one second panel to simultaneously strip or machine both the edge of the at least one first panel and the edge of the at least one second panel, and
a second welding position, wherein the edge of the at least one first panel and the edge of the at least one second panel are adjacent and resting on the at least one anvil body.
11. The system according to claim 10 , wherein the mover comprises a movable support, on which is positioned the at least one first panel, and comprises a mechanism for guiding the movable support in relation to a first lateral part of the at least one anvil body.
12. The system according to claim 11 , wherein the at least one anvil body has an upper support surface with a curved shape so as to marry up with a shape of an aircraft nose section.
13. The system according to claim 11 , further comprising a positioner for positioning the at least one first panel and the at least one second panel.
14. The system according to claim 11 , wherein the positioner comprises pins mounted on the movable support to engage with holes of the at least one first panel and the at least one second panel.
15. The system according to claim 10 , further comprising a holder to hold the at least one first panel and the at least one second panel, comprising at least one suction table arranged to receive an edge of a panel of the plurality of panels to be joined.
16. The system according to claim 15 , wherein the at least one suction table comprises a heat dissipater.
17. The system according to claim 10 , wherein the tool comprises a machining tool mounted on the tool holder of the at least one anvil rail.
