Problems solved by technology

[0003] However, the two-degree-of-freedom joint structure of the robot in the prior art has inherent defects, such as large structure, high manufacturing cost, low structural integration, low strength, inaccurate positioning, difficult control, and low load capacity. Both limit the development of bionic robots, and are not convenient for the popularization and use of two-degree-of-freedom joint structures

Abstract

The invention relates to the technical field of multi-degree of freedom joints, in particular to a two-degree of freedom serial servo joint structure. The two-degree of freedom serial servo joint structure comprises a top plate, an inclined plate, a first-degree-of-freedom mechanism and a second-degree-of-freedom mechanism, wherein a through hole for accommodating the inclined plate is formed in the top plate; the first-degree-of-freedom mechanism comprises an electric ejector rod, linkage plates symmetrically arranged at the bottom of the inclined plate, top plate connecting plates symmetrically arranged at the bottom of the top plate, and a first bearing connecting component; the second-degree of freedom mechanism comprises a primary gear, a secondary gear and a motor fixedly connected with the inclined plate, and a second bearing connecting component. The two-degree of freedom serial servo joint structure provided by the invention is simple in structure, low in manufacturing cost, convenient to mount, use and control, relatively high in universality and practicality, long in service life, and convenient to popularize and use.

Description

Technical field [0001] The invention relates to the technical field of multi-degree-of-freedom joints, in particular to a two-degree-of-freedom series servo joint structure. Background technique [0002] With the development of robot technology, the types of robots continue to increase, and the requirements for the flexibility, compactness, intelligence, and controllability of robot joints are getting higher and higher. Two-degree-of-freedom joint refers to a joint with two degrees of freedom perpendicular to the axis. The prototype of this joint is common in humans and animals, such as the neck joints, wrist joints, ankle joints, and phalangeal joints of humans and other walking animals. , Waist joints, leg joints of crabs and other reptiles. Therefore, for various bionic robots, making joints with two degrees of freedom is one of the problems that need to be solved. [0003] However, the two-degree-of-freedom joint structure of the robot in the prior art has inherent defects, s...
