Abstract

Disclosed is an aerodynamic driver, comprising a left end cover and a right end cover, wherein an inflation hole is arranged on the left end cover and the two ends of a rubber tube are respectively in sealed connection with the left end cover and the right end cover. The invention is characterized in that the outer side of the right end cover is fixedly connected with a rigid inner neck bush, which is nested on the outside of the rubber tube and can be clung glidingly on the outer wall of the rubble tube; the outer side of the left end cover is fixedly connected with a rigid outer neck bush, which is nested on the outside of the inner neck bush and can be clung glidingly on the outer wall of the inner neck bush.

Description

(1) Technical field [0001] The invention belongs to a driver, in particular to a pneumatic driver, which is suitable for designing and manufacturing multi-fingered dexterous hands. (2) Technical background [0002] Efficient and flexible drives are the basis and prerequisite for the design of robotic multi-fingered dexterous hands. Traditional robotic multi-fingered dexterous hands mostly use motors as drives, and their structural size is large, making it difficult to miniaturize multi-fingered dexterous hands. Pneumatic joints are also proposed, such as invention patent No. 200510049589.5, the patent name is an invention patent of a flexible actuator, which discloses a pneumatic flexible actuator, which consists of a left end cover, a rubber tube, a spring nested in the rubber tube wall, a right end cover, Composed of pipe joints, the invention also has the following disadvantages: 1. The spring is nested in the rubber tube, the manufacturing process is complicated and the ...
