Rotor tilting device for coaxial twin-rotor aircraft

The invention relates to the technical field of unmanned aerial vehicle equipment, in particular to a rotor tilting device for a coaxial dual-rotor aircraft. The rotor tilting device comprises a pair of adjusting assemblies used for pushing the blades to turn over in the horizontal plane, a first steering engine and a second steering engine. The adjusting assembly and a main shaft of the coaxial dual-rotor aircraft are coaxially arranged. The pair of adjusting assemblies are symmetrically arranged on the two sides of the fixing frame, and the first steering engine and the second steering engine form linkage inclined overturning adjustment on the upper rotor wing assembly and the lower rotor wing assembly through the pair of adjusting assemblies. A swash plate of the adjusting assembly is connected with the main shaft through a fisheye bearing, and the side wall of the swash plate is sleeved with a connecting piece. The swash plate is connected with the first steering engine and the second steering engine thro
