Flying mechanical arm quick connection and separation device based on single motor drive

Abstract

The invention discloses a flying mechanical arm quick connection and separation device based on single motor drive. The flying mechanical arm quick connection and separation device based on single motor drive comprises a transition connection top seat and a transition connection base, wherein the transition connection top seat is fixedly connected to an unmanned aerial vehicle; the transition connection base is fixedly connected to mechanical arms; a sinking groove adapted to the shape of the transition connection top seat is formed in the top surface of the transition connection base; a circular groove is formed in the center of the bottom surface of the transition connection top seat; the interior of the circular groove is rotatably in sleeve connection with a disc; a motor is fixed to the top of the transition connection top seat; an output shaft of the motor is connected to the disc in a transmission manner; more than there sliding chutes are uniformly distributed on the bottom surface of the transition connection top seat in a peripheral direction by centering on the disc; the interior of each sliding chute is connected to a sliding block in a sliding manner; one end of each sliding block is articulated with the disc through a connecting rod piece; and an inner annular groove is formed in the bottom of the side wall of the sinking groove. The flying mechanical arm quick connection and separation device based on single motor drive can realize quick installation and disassembly of the unmanned aerial vehicle and the mechanical arms, has simple structure and small volumeand is convenient and quick to install and disassemble.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a fast connection and separation device for a flying manipulator driven by a single motor. Background technique [0002] UAVs can maneuver in a wide airspace. Therefore, flying robots are being rapidly applied in civil fields such as forest fire prevention monitoring, large-scale pesticide spraying of crops, aerial relay monitoring of exhibitions, and disaster monitoring and control in disaster areas. [0003] With the expansion of the potential application range of small UAVs, in recent years, based on the purpose of flying robots to grasp specific targets, small rotor flying robots with manipulators are becoming one of the research frontiers of internationally renowned research institutions. The flying manipulator refers to the manipulator installed under the fuselage of the rotor UAV to complete the task of grasping and moving special targets. [0004] At present, ther...

AI Technical Summary

Problems solved by technology

[0009] (1) Due to the narrow space at the bottom of the rotor UAV, it is not easy to disassemble and assemble when directly connected by bolts;

[0010] (2) Because although the bolts are fully fitted before, the manipulator needs to move frequently, which will cause the bolts to loosen;

[0011] (3) If the disassembly and assembly are repeated many times, the bolt and nut connection method is easy to fail, so it may cause frequent replacement;

[0012] (4) In the process of movement, it will be subjected to large axial tension and shear force of the section, which will greatly increase the probability of failure of bolts and nuts. Once the safety is not guaranteed, it will cause drones and manipulators to fail. The unreliability of the connection is greatly increased
