Abstract:
1. A clamping mechanism for clamping at least two structural components to each other, said clamping mechanism comprising a clamping bail forming a clamping opening, a first clamping section ( 9 ) carried by said clamping bail to face across said clamping opening, a second clamping section ( 10 ) carried by said clamping bail to face across said clamping opening in axial alignment with said first clamping section ( 9 ), said axial alignment defining a drilling axis, said first clamping section ( 9 ) comprising a guide element with a guide channel ( 11 ) adapted to guide a drill bit (DB) driven by a drilling tool along said drilling axis, a guide hole ( 11 ) in said guide element, a locating pin ( 12 ) movable in said guide hole ( 11 ′) along a pin axis extending at an angle to said drilling axis, said locating pin ( 12 ′) being axially movable along said guide hole ( 11 ′) in said guide element to reach into said guide channel ( 11 ) for positioning a first structural component of said at least two structural components in a correct drilling position, said locating pin ( 12 ′) being also sufficiently moveable for moving out of said guide channel ( 11 ) and wherein said second clamping section ( 10 ) comprises a pressure member ( 15 ) and a clamping drive for pressing said pressure member ( 15 ) against a second structural component of said at least two structural components and against said first structural component to establish a clamped position for said at least two structural components.
