Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] Referring to Figures 1 to 4, a pneumatic flexible torsion joint is composed of an arc-shaped pneumatic flexible cylinder 1, a first end cover 2, a second end cover 3, a fixed disc 4, a central shaft 5 and a circular turntable 6, and the arc The left and right ends of the shaped pneumatic flexible cylinder 1 are respectively connected with the first end cover 2 and the second end cover 3. Due to its inherent arc shape, the arc-shaped pneumatic flexible cylinder can ensure that it can elongate along the arc during rotation. or contraction; the first end cover 2 has a through hole to communicate with the outside atmosphere, and one end of the second end cover 3 is closed, and two arc-shaped pneumatic flexible cylinders 1 of the same size are symmetrically placed on the fixed disk 4 left and right in the center, and the fixed disk 4 is equipped with a central axis 5...

Abstract

The pneumatic flexible torsional knuckle includes one fixed disc, one middle axle and one circular rotating disc. The middle axle is mounted onto the fixed disc and has its upper end connected to the circular rotating disc. On two sides of the fixed disc, there are two flexible pneumatic cylinders with one first end cap and one second end cap each. The first end caps are connected to the fixed disc and have through hole to atmosphere; and the second end caps are connected to the circular rotating disc. Each of the flexible pneumatic cylinders includes an arc rubber tube, one spring steel wire wound closely in the inner wall of the rubber tube. The pneumatic flexible torsional knuckle of the present invention has simple reasonable structure and small size.

Description

(1) Technical field [0001] The invention is a torsion joint, which belongs to the pneumatic flexible torsion joint, and is suitable for designing and manufacturing flexible manipulators and other occasions. (2) Background technology [0002] In today's world, most of the driving parts of motor-driven robots and hydraulic-driven robots are reciprocating or rotating. When they are used to make the joints of robots, it is usually necessary to have a set of mechanical devices to convert reciprocating or rotating motion into other motion modes required. Robot joints designed in this way may have the advantages of high precision and high output power; but these designs are often bulky, complex and expensive, and their flexibility is far behind that of human joints. [0003] The application prospects of dexterous robots have been generally recognized by people, and because of the above shortcomings of contemporary robot drive components, the research on dexterous robot drive compo...
