Abstract

The invention discloses a variable-posture joint type dexterous hand, and belongs to the technical field of mechanical hands. The variable-posture joint type dexterous hand comprises a base, a jacking assembly and a clamping assembly, wherein the jacking assembly and the clamping assembly are arranged on the base; the jacking assembly is in sliding fit with the base; and the clamping assembly comprises a plurality of multi-connecting-rod fingers which are connected to the edge of the base and can be changed in form. According to the variable-posture joint type dexterous hand, the jacking assembly and the clamping assembly are arranged on the base, the multi-connecting-rod fingers capable of changing various grabbing forms are arranged on the clamping assembly; and when an object needs to be grabbed, the jacking assembly is used for jacking the top surface of the object, the multi-connecting-rod fingers are used for grabbing the outer side of the object, the object is grabbed through the cooperation of the jacking assembly and the clamping assembly, and therefore the grabbing function under the condition of the complex contour of the object is realized.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to a dexterous hand with variable posture joints. Background technique [0002] A manipulator is an automatic operating device that can imitate certain movement functions of the human hand and arm to grab, carry objects or operate tools according to a fixed program. The feature is that various expected operations can be completed through programming, and the structure and performance have both the advantages of man and robot. The manipulator is the earliest industrial robot and the first modern robot. It can replace the heavy labor of people to realize the mechanization and automation of production, and can operate in harmful environments to protect personal safety. Therefore, it is widely used in machinery manufacturing, metallurgy, Departments of electronics, light industry and atomic energy. In the prior art, the grasping structure of the manipulator is relatively simple, ...
