Abstract

A pneumatic flexible joint is composed of a rubber pipe consisting of external and intenal layers, two end covers with a central through hole for each and linked to both ends of said rubber pipe in sealing mode, and the metallic wires consisting of a spiral steel wire and a restrictive steel wire and arranged between said internal and external layers of rubber pipe.

Description

(1) Technical field [0001] The invention belongs to a bending joint, in particular to a pneumatically flexible bending joint, which is suitable for the occasion of designing and manufacturing a mechanical dexterous hand. (2) Background technology [0002] The design of the joint is a key technology in the design and manufacture of the mechanical finger. The sensitivity of the joint and the complexity of the joint structure directly determine the structure and size of the manipulator. The traditional design idea is based on a purely mechanical structure. The bending joints of the manipulator are formed in the form of pulleys, steel cables, and chains. The main disadvantage is that an external transmission mechanism is required, and a motor or hydraulic drive is required. The space size is large, the structure is complex, and the power is heavy. The ratio is small, the control is difficult, and the implementation effect is affected. Pneumatic artificial joints are also propos...
