Problems solved by technology

However, the existing Pneumatic Muscle also has the following obvious disadvantages: (1) The requirements for pneumatic actuators in most working conditions are to be able to output force and linear motion during the working stroke, and the return stroke can be automatically completed
[0003] Due to the above-mentioned shortcomings of the existing Pneumatic Muscle, its application in related fields is severely limited

Embodiment Construction

[0015] In the following, the two technical solutions of the present invention will be further elaborated in conjunction with the drawings of two specific embodiments.

[0016] attached figure 1 with attached figure 2 Shown is a specific embodiment of a technical solution of the present invention. It can be seen from the figure that the pneumatic muscle is composed of a rubber tube 2 and a left nest 3 and a right nest 4 fixed at both ends of the inner hole; the left end of the left nest 3 has a breathing hole 31 and the air intake and exhaust of the working chamber. Hole 32. The outer surface of the right part of the left nesting part 3 is inserted into the inner hole of the left part of the right nesting part 4, and cooperates with each other to slide and nest to form an internal linear motion guide. The inner holes of the left nesting part 3 and the right nesting part 4 form an inner cavity, and a compression spring 5 is arranged in the inner cavity to form an automatic r...

Abstract

A key element of an existing pneumatic muscle tendon is a knitted rubber hose made of non-rigid materials, and linear motion output and automatic resetting can only be achieved by externally arranging a linear motion guiding and returning device, accordingly, not only is the structure of an overall device not very compact, but also the comprehensive manufacturing cost is high. Besides, energy consumption of the existing pneumatic muscle tendon is as high as 4 times or more of that of a corresponding cylinder under the conditions of identical inner diameters, strokes and rated pressure. According to an energy-saving pneumatic muscle tendon, an internal linear motion guiding device is adopted, a compression spring is used for forming elastic potential energy to constitute an automatic resetting device, and an internal air capacitor is used for forming a pressure potential energy automatic resetting device; two types of energy-saving pneumatic muscle tendons capable of outputting liner motion and resetting automatically are designed. The novel pneumatic muscle tendon is energy-saving and environment-friendly, compact in overall structure, low in comprehensive manufacturing cost, complete in function and wide in application range.

Description

technical field [0001] The invention relates to the field of actuators for pneumatic transmission, and mainly relates to two types of inner-guided linear motion automatic reset and energy-saving pneumatic muscles. Background technique [0002] Pneumatic muscle, also known as pneumatic muscle, is a new type of pneumatic actuator developed in the recent period to provide one-way tension. Its technical feature is to fill the sealed braided hose with compressed gas to expand the internal volume of the braided hose. Tensile force is generated by increasing in size and shortening in longitudinal length. Compared with traditional cylinders, Pneumatic Muscle has the advantages of small size, light weight, and the output force of the same inner diameter is an order of magnitude higher than that of cylinders. However, the existing Pneumatic Muscle also has the following obvious disadvantages: (1) Most working conditions require the pneumatic actuator to be able to output force and li...
