Bionic flexible claw device inspired by caudal fin of Longfeng brocade carp

Abstract

The invention relates to a bionic flexible claw device inspired by the caudal fin of a Longfeng brocade carp. The bionic flexible claw device comprises a motor mounting surface, a lifting platform surface and bionic flexible mechanical claws. A motor is arranged on the motor mounting surface, and a shape coupler with an external thread is connected on an output shaft of the motor, and the liftingplatform surface is in threaded connection with the shaft coupler. A plurality of connecting rods are uniformly arranged on the periphery of the lifting platform surface. The top end of each connecting rod is movably connected on the lifting platform surface, and the tail end of each connecting rod is movably connected with one bionic flexible mechanical claw. The edge of the inner side of the upper end face of each bionic flexible mechanical claw is movably arranged on the lower end face of the motor mounting surface. The positive-negative rotation of the motor is controlled, so the lifting down or up of the lifting platform surface is realized. The lifting platform surface lifts down, so that each bionic flexible mechanical claw moves downwards to close around the edge of the inner sideof the upper end face, and the bionic flexible mechanical claw deforms according to the shape of a target object to form an enveloping surface and complete the grasping action. The lifting platform surface lifts up, each bionic flexible mechanical claw moves upwards to open around the edge of the inner side of the upper end face so as to complete the release action.

Description

technical field [0001] The invention relates to the technical field of mechanical claw design, in particular to a bionic flexible claw device inspired by the tail fin of dragon, phoenix and koi carp. Background technique [0002] Mechanical claws can imitate certain functions and actions of human hands and arms, and can be used to grasp, clamp, transfer and carry objects, and can replace manual operations for dangerous or heavy operations. It is an automatic operating device that is used in medical equipment, logistics It is widely used in transportation and other fields. [0003] At present, the common mechanical claws are mostly clamping type, which are usually rigid structures and have relatively complex configurations, and are generally used to grab external hard and regular-shaped objects. However, when the grasped object is fragile, easily deformed or irregular in shape, the mechanical claw of this rigid structure is easy to cause damage to the object, or it is diffic...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the limitations and deficiencies of existing mechanical claws when grasping fragile, deformable or irregularly shaped objects, the present invention provides a bionic flexible claw device inspired by the tail fin of dragon and phoenix koi. As a bionic object, by studying its morphological structure and movement mode, the flexible mechanical claw is designed according to the bionic idea. Through the structural layout and stepping motor drive, a complete and feasible set of bionic flexible claw device inspired by the tail fin of dragon, phoenix and koi carp is formed to solve the problem of Grasping, clamping and handling of deformable, fragile and irregularly shaped objects
