Abstract

The invention discloses a variable-stiffness flexible driver, comprising an integral support, a double-layer inner and outer compression airbag cavity is installed in the center of the integral support, a connecting base is connected to the lower end of the double-layer inner and outer compression airbag cavity; the double-layer inner and outer compression airbag cavity is The body is composed of an outer airbag cavity and an inner airbag cavity. The outer airbag cavity is connected to the air pump 1 by an external air tube, and the inner air bag cavity is connected to the air pump 2 by an external air tube. The bottom of the outer air bag cavity is connected to a suction cup. The invention has a simple structure, uses the air suction of a micro air pump as a control source, has stable performance, high precision, high efficiency, and uses less energy, and is suitable for long-term continuous work.

Description

technical field [0001] The present invention relates to the technical field of a manipulator driver, and more particularly, to a variable stiffness flexible driver. Background technique [0002] A manipulator refers to an automatic operation device that can imitate some action functions of human hands and arms to grab, carry objects or operate tools according to a fixed program. It can replace the heavy labor of humans to realize the mechanization and automation of production, and can operate in harmful environments to protect personal safety, so it is widely used in machinery manufacturing, metallurgy, electronics, light industry and atomic energy. [0003] The structure of the manipulator imitates human fingers, and it is divided into three types: jointless, fixed joint and free joint. The number of gripping devices can be further divided into two fingers, three fingers, four fingers, etc., of which two fingers are used the most. Chucks of various shapes and sizes can be...
