Abstract

In order to overcome the defects that a flexible arm is insufficient in rigidity, small in bearing capacity and the like, the invention provides a nested restraint ring flexible arm with a braking function, which mainly comprises a driving assembly and a braking assembly, wherein the driving assembly achieves controllable bending and stretching in any direction of a three-dimensional space by adjusting the pressure of fluid introduced into artificial muscles; a plurality of restraint rings of the driving assembly are of a nested structure, and the anti-torsion function of the flexible arm is achieved. The braking assembly mainly utilizes the friction braking principle to introduce pressure fluid into a braking air bag and extrude a braking rod to form braking force so as to achieve the braking purpose, the larger the pressure of the introduced fluid is, the larger the braking force is, by adjusting the pressure of the fluid introduced into the braking air bag, stepless control over the braking force can be achieved, and the flexible arm can be kept in any posture, and the braking effects are obvious. The nested restraint ring flexible arm is simple in structure, flexible in movement and convenient to use.

Description

technical field [0001] The invention belongs to the field of flexible robots, in particular to a nested restraint ring flexible arm with a braking function. Background technique [0002] Flexible robotic arms have been extensively studied due to their flexibility, flexibility, and safety in human-computer interaction. However, insufficient rigidity and poor bearing capacity have become the main shortcoming of flexible robotic arms. In order to solve the problem of robot joint pose maintenance and joint damping adjustment, researchers have done a lot of research on robot joint brakes, mainly including drum brakes, disc brakes, friction brakes, electromagnetic brakes and piezoelectric ceramic brakes, Harbin Ma Jun and others from the University of Technology designed a disc brake applied to the robot joint. The friction disc of the brake and the brake disc are provided with the same annular boss, and the braking torque reaches 3N·m, but the size is too large. The outer diamet...
