Drill-and-hole detector tool, method of utilization thereof and uses
View Patent ↗The invention relates to a drill-and-hole detector tool consisting of at least two plates ( 1 a and 1 b ) having the first plate ( 1 a ) at least three passing holes ( 2 b ) at one end, and a chimney ( 3 ) used as a drilling guide at the other end and having the second plate ( 1 b ) at least three pins ( 2 a ) at one end and a positioning rivet or stub ( 4 ) at the other end, in such a way that when the two plates ( 1 a and 1 b ) are superimposed, the three passing holes ( 2 b ) of the first plate ( 1 a ) coincide with the three pins ( 2 a ) of the second plate ( 1 b ), and the chimney ( 3 ) of the first plate ( 1 a ) coincides with the positioning rivet or stub ( 4 ) of the second plate ( 1 b ).
1. A drill-and-hole detector tool comprising at least two plates ( 1 a and 1 b ) wherein the first plate ( 1 a ) possesses at least three passing holes ( 2 b ) at one end and a chimney ( 3 ) which is used as a drill guide at the other end, and the second plate ( 1 b ) possesses at least three studs ( 2 a ) at one end and a positioning rivet or stub ( 4 ) at the other end, in such a way that when the two plates ( 1 a and 1 b ) are superimposed, the three passing holes ( 2 b ) of the first plate ( 1 a ) coincide with the three studs ( 2 a ) of the second plate ( 1 b ), and the chimney ( 3 ) of the first plate ( 1 a ) coincides with the positioning rivet or stub ( 4 ) of the second plate ( 1 b ), wherein the first plate ( 1 a ) further comprise at least one additional hole ( 9 ) and a screw ( 10 ), said hole ( 9 ) being located in the middle of the three passing holes ( 2 b ) and threaded.
2. The drill-and-hole detector tool according to claim 1 , wherein the chimney ( 3 ) and the positioning rivet or stub ( 4 ) are interchangeable according to a diameter of a hole to copy ( 6 ).
3. A method of utilization of the drill-and-hole detector tool according to claim 1 , comprising:
choosing the positioning rivet or stub ( 4 ) of a diameter equal to that of a hole to copy ( 6 ),
positioning the second plate ( 1 b ) in such a way that the positioning rivet or stub ( 4 ) is located on the hole to copy ( 6 ),
locating a new piece to drill ( 5 ), on the second plate ( 1 b ),
locating the first plate ( 1 a ) of the drill-and-hole detector tool ( 8 ) on the new piece to drill ( 5 ), fitting the first plate ( 1 a ) exactly via the passing holes ( 2 b ) in the studs ( 2 a ) of the second plate ( 1 b ), already positioned,
passing through and threading the screw ( 10 ) into the additional hole ( 9 ), and
fitting a drill bit ( 7 ) into the chimney ( 3 ) and drilling to the required diameter.
4. A method comprising:
providing the drill-and-hole detector tool according to claim 1 ; and
operating the drill-and-hole detector tool to interchange an actuator fitting of a ramp for a main landing gear of an aircraft.
5. A method comprising:
providing the drill-and-hole detector tool according to claim 1 ; and
operating the drill-and-hole detector tool to perform an in situ repair of a fuselage of an aircraft.
