Problems solved by technology

[0003] The mature pneumatic muscles on the market include the pneumatic muscles produced by FESTO and SHADOW. Both types of pneumatic muscles have the function of active contraction in the axial direction, but they do not have the function of active rotation in the axial direction; at the same time, the friction between the braided fibers The resulting hysteresis problem is difficult to solve

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0011] Such as figure 1 , figure 2 As shown, the present invention includes an elastic outer tube 1, an outer fiber filament 2, an elastic inner tube 3, an inner fiber filament 4, a first trachea connector 5, a second trachea connector 6, a gap 7, an inner tube cavity 8, a first clip Hoop 9, second clamp 10, gap vent 11, inner tube cavity vent 12; the elastic outer tube 1 and the elastic inner tube 3 are all rubber elastic hoses, which expand after inflation; and the diameter of the elastic outer tube 1 To be larger than the diameter of the elastic inner tube 3, the elastic outer tube 1 is sleeved on the outside of the elastic inner tube 3, and there is a gap 7 between the elastic outer tube 1 and the elastic inner tube 3; The thread 2 adopts a right-handed winding direction, and at the same time, the surface of the elastic inner tube 3 is w...

Abstract

The invention belongs to the pneumatic artificial technical field, and particularly relates to double-tube sleeved type pneumatic artificial muscle.The double-tube sleeved type pneumatic artificial muscle comprises an elastic outer tube, outer cellosilk, an elastic inner tube, inner cellosilk, a first air pipe connector, a second air pipe connector, a gap, an inner tube cavity, a first clamp, a second clamp, a gap vent and an inner tube cavity vent.By controlling the relationship of air pressure in the gap and air pressure in the inner tube cavity, active axial contraction and active axial rotation of the double-tube sleeved type pneumatic artificial muscle are achieved.Compared with pneumatic muscle of the same model in the market, the double-tube sleeved type pneumatic artificial muscle has the advantage that air consumption is lower, so that energy saving is better achieved.The performance of the pneumatic muscle is improved and enriched, functional innovation and expansion are achieved, and the double-tube sleeved type pneumatic artificial muscle is worth application.

Description

technical field [0001] The invention belongs to the field of pneumatic artificial technology, in particular to a double-tube suit type pneumatic artificial muscle. Background technique [0002] As a new type of pneumatic actuator, pneumatic muscles have great similarities with biological muscles, and have the advantages of high flexibility, light weight, convenient use, fast response, and low cost. They are widely used in robotics, bionic machinery and other fields. . The pneumatic muscle is mainly composed of three parts: an inflatable elastic hose, a braided mesh that constrains the expansion and deformation of the elastic hose, and a clamp. The braided mesh that constrains the deformation of the elastic hose is woven from two kinds of winding fiber filaments, one group of fiber filaments is wound left-handed around the hose, and the other group of fiber filaments is wound right-handed around the hose. [0003] The mature pneumatic muscles on the market include the pneum...
