Problems solved by technology
In the actual application process, there are two situations of pressure and tension in most cases. The single-acting pneumatic artificial muscle obviously cannot fully meet the needs of current applications, which also greatly limits the promotion and application of pneumatic artificial muscles.

Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing:
[0025] Such as figure 1 and figure 2 As shown, the present invention mainly includes an end cover, a gland, a push airbag 4 and a pull airbag 5, the end cover includes an end cap A1, an end cap B8; the gland includes a gland A2, a gland B3, a gland Cover C7 and gland D6; the push airbag and the pull airbag are coaxially arranged inside and outside, and the push airbag is placed inside the pull airbag; the push airbag is made of rubber material, and the push airbag is placed inside the push airbag The wall is sequentially provided with annular holes with shuttle-shaped cross-sections, and two annular holes with circular cross-sections are arranged between two adjacent holes; An annular rigid cage 9 is embedded in the side capsule wall. The gland A and the gland C are respectively connected to the two ends of the push airbag, and the push airbag is fixedly connected to th...

The invention discloses a double-acting pneumatic artificial muscle. The double-acting pneumatic artificial muscle comprises a push stroke air bag, a pull stroke air bag, end covers and fasteners. The end covers comprise the end cover A and the end cover B. Glands comprise the gland A, the gland B, the gland C and the gland D. The push stroke air bag is arranged inside the pull stroke air bag in a coaxial manner. The gland A and the gland C are connected to the two ends of the push stroke air bag and fixedly connected with the end cover A and the end cover B correspondingly. The gland B and the gland D are connected to the two ends of the pull stroke air bag and fixedly connected with the gland A and the gland C correspondingly. When an inner chamber of the push stroke air bag is inflated with gas, the inner wall is squeezed by gas pressure; the diameter of the inner chamber is increased; spindle-shaped annular holes are narrowed in the radial direction of the push stroke air bag and widened in the axial direction of the push stroke air bag, and thus the push stroke air bag is elongated; and the push stroke effect of the double-acting pneumatic artificial muscle is achieved. When an inner chamber of the pull stroke air bag is inflated with gas, the pull stroke air bag is enlarged in the radial direction and shortened in the axial direction; the pull stroke air bag is shortened; and the pull stroke effect of the double-acting pneumatic artificial muscle is achieved. The double-acting pneumatic artificial muscle has the beneficial effects of being ingenious in structure, convenient to use, easy to operate and the like.
Description
technical field [0001] The invention relates to the field of artificial muscles, in particular to a double-acting pneumatic artificial muscle. Background technique [0002] Artificial muscles are proposed with the development of robotics for the functional requirements of driving components, generally speaking, they refer to materials or devices with biomechanical properties similar to biological skeletal muscles. The artificial muscles widely studied at home and abroad can be divided into three categories: electropolymers, shape memory alloys and pneumatic artificial muscles. [0003] Among them, the pneumatic artificial muscle deforms by compressing air, thereby generating force and displacement effects on the outside world. Pneumatic artificial muscles can be divided into four categories according to their structure: braided pneumatic artificial muscles, mesh pneumatic artificial muscles, embedded pneumatic artificial muscles and special pneumatic artificial muscles. At...
