Problems solved by technology
The existing grabbing devices include sucker sucking and mechanical grabbing. The sucker sucking is limited by the roughness of the surface of the object and the grabbing angle. The mechanical grabbing is limited by the size and grabbing angle. The grabbing methods are relatively clumsy and single. Unstable and unable to meet the current needs, which limits the improvement of drone transportation efficiency and the realization of automation

Embodiment Construction
[0022] The invention will be further described below in conjunction with the accompanying drawings.
[0023] Such as figure 1 As shown, a kind of freestyle multi-angle mechanical arm used on the aircraft provided by the present invention includes two large steering gears 1, four thrust rods 2, four connecting rods 3, two claw mounting brackets 4, two Ball end rod end joint bearing L-type universal joint 5, two disc claws 6, eight small steering gears 7, eight tips 8, a mounting frame 9 and some lightening holes 10 provided on the mounting frame 9.
[0024] The two large steering gears 1 are respectively connected to the two thrust rods 2 and fixedly connected to the same side of the mounting frame 9, so that the thrust rod 2 can rotate with the rotation of the steering gear at a fixed axis, and the other two thrust rods 2 are directly connected to the mounting frame On the other side of 9, two symmetrical thrust rods 2 on the opposite side are connected with the same claw mou...

The invention discloses a free multi-angle mechanical arm for an aircraft, and belongs to the technical field of aircraft clamping jaw devices. The mechanical arm comprises two large steering engines,two parallel four-bar mechanisms, two claw mounting racks, two universal joints, two disc claws and a mounting rack. Compared with the prior sucker sucking, a defect that the traditional mechanical grabbing is clumsy is overcome, the mechanical structure and the universal joints are ingeniously combined to serve as a main body structure, and the steering engines control the length of the tip of the claw surface, so that more safe and reliable multi-angle grabbing can be realized. According to the mechanical arm, an article can be grabbed by gravity self-locking without external force, and meanwhile, the posture of the article can be freely adjusted after the article is grabbed through the universal joints, so that the center of gravity of the article and the center of gravity of the aircraft are on the same vertical straight line, and a situation that the flight attitude of the aircraft is influenced by the deviation of the center of gravity of the whole aircraft due to the deviationof the grabbing position is avoided.
Description
technical field [0001] The invention belongs to the technical field of aircraft clamping claw devices, and in particular relates to a free-style multi-angle mechanical arm used on aircraft. Background technique [0002] At present, the application fields of drones are getting wider and wider. Remote control flight is the basic feature of drones. Monitoring infectious diseases, surveying and mapping, news reports, power inspections, disaster relief film and television shooting, etc. Since UAVs have the characteristics of good maneuverability, quick task response, and timely information feedback, the use of UAVs for air transportation has become an important development direction. The current drone air transport is mainly used for military purposes, and can transport the wounded, weapons and ammunition, food and water, etc. The high efficiency of the drone can send the wounded to the hospital faster. Civilian transport drones can be used to deliver medical supplies, express ...
