Problems solved by technology
[0003] There are reserved holes on the outer end of the arm and the bottom of the motor of the multi-rotor aircraft. During the assembly process, the operator needs to use a small screwdriver to tighten the hexagonal screws on the rotor and the motor. However, the rotor is limited by the material. During the process, the operator uses a screwdriver to tighten each hexagon socket screw to a different degree of force. Once the force is improper, it will cause cracks in the reserved hole of the rotor, which will have a great impact on the stability of the motor.

Abstract
The invention discloses a multi-rotor intelligent unmanned aerial vehicle assembly table which comprises a limiting mechanism, a rotor assembly mechanism and a shockproof mechanism, and the limiting mechanism comprises a positioning piece used for clamping the outer end of a rotor, an inclined frame installed at the bottom of the positioning piece and a bottom support connected to the inclined frame. The stability augmentation piece is arranged, the main shaft rod and the auxiliary shaft rod which are distributed in the circumferential direction are movably installed in the stability augmentation piece, the bases are movably connected to the top ends of the main shaft rod and the auxiliary shaft rod, a plurality of nuts installed at the top end of the stability augmentation piece are used for restraining screw rods at the bottoms of the bases, and a transverse shaft is combined with meshing transmission of a fluted disc at the bottom end of the main shaft rod; when the whole stability augmentation piece is in a rising state, hexagon socket head cap screws placed in the multiple bases can be synchronously pressurized and delivered into holes reserved in the outer ends of the rotors, meanwhile, the main shaft rod can drive the chain and the three auxiliary shaft rods to synchronously rotate in combination with rotation of the transverse shaft, and therefore stability augmentation is achieved. And the plurality of bases and the inner hexagonal screws in the bases are enabled to be tightened with uniform force towards the bottom end of the motor, so that the rapid installation of the motor at the outer end of the rotor wing can be effectively ensured.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicle rotor assembly, in particular to a multi-rotor intelligent unmanned aerial vehicle assembly platform. Background technique [0002] Unmanned aerial vehicle refers to an aircraft that does not carry an operator and can fly autonomously or remotely. A multi-rotor unmanned aerial vehicle is a special unmanned helicopter with three or more rotor shafts. Rotate, drive the rotor, thereby generating lift thrust. [0003] There are reserved holes on the outer end of the arm and the bottom of the motor of the multi-rotor aircraft. During the assembly process, the operator needs to use a small screwdriver to tighten the hexagon socket screws on the rotor and the motor. However, the rotor is limited by the material. During the process, the operator uses a screwdriver to tighten each hexagon socket screw to different degrees of force. Once the force is improperly applied, cracks will occur in...
