Description
Technical Field
The patent relates to a pneumatic combination joint of multistage formula adopts the combination of each part to form the structure of multistage formula, fills compressed gas in corresponding trachea through the control, makes the rubber tube inflation of intercommunication, drives each section joint bending. After the trachea is deflated, the rubber tube retracts, and the spring drives each section of joint to return to a linear state.
Background
The common pneumatic joints are usually made of materials such as silica gel and rubber tubes, and each section of joint is only provided with one inflated silica gel and rubber tube, and after being inflated with compressed gas, the joint can be bent only in one direction. If the direction of the bending movement is changed, the bending movement must be remade and assembled, which causes inconvenience in use.
Disclosure of Invention
The technical problem that this patent was solved provides a pneumatic combination joint of multistage formula. The joints are assembled according to action requirements, and because each joint is provided with four rubber pipes, any one or two of the rubber pipes can be inflated to expand the communicated rubber pipes, so that the springs are driven to bend towards one side of the rubber pipes which are not inflated to enable the joints to bend and move according to a set direction. After the trachea is deflated, the rubber tube retracts, and the spring drives the joint to return to a linear state. The rubber tubes of all the joints are inflated by selection and control, so that all the joints of the multi-section pneumatic combined joint can realize multidirectional bending motion, and various actions can be completed. The multi-section pneumatic combined joint can simulate the motion of human arms, the motion of industrial robots, the motion of reptiles and the like, and can be used in various industrial and civil occasions.
The multi-section pneumatic combined joint mainly comprises an air pipe, a base, a joint, a rubber pipe, a large clamp, a spring, a small clamp and a plugging sleeve; the connector is fixed on the base through threaded connection, the inflation tube is sleeved at the small end of the connector and clamped by the small clamp, the two ends of the rubber tube are sleeved at the large end of the connector and clamped by the large clamp, the two ends of the spring are respectively sleeved on the cylinder at the center of the base, and the plugging sleeve is sleeved at the small end of the connector connected with the rubber tube and clamped by the small clamp.
According to the use requirement, the multi-joint bending device can be assembled and overlapped into a multi-section structure at will to realize multi-joint bending motion.
Because each joint is provided with four rubber tubes, one or two of the four rubber tubes can be inflated to expand the rubber tubes, so that the spring is driven to bend towards one side of the rubber tube without being inflated, and the joint is bent to move according to a set direction. After the trachea is deflated, the rubber tube retracts, and the spring drives the joint to return to a linear state. The rubber tubes of all the joints are inflated by selection and control, so that all the joints of the multi-section pneumatic combined joint can realize multidirectional bending motion, and various actions can be completed. An actuating mechanism can be arranged at the tail end of the multi-section pneumatic combined joint to realize various specific functions.
The air pipe, the rubber pipe, the large clamp, the spring, the small clamp and the plugging sleeve of the multi-section pneumatic combined joint can be made of suitable materials and parts on the market. The base and the joint are made of light materials, a 3D printing mode can be adopted, and batch production can be realized through a mold.
The multi-section pneumatic combined joint can simulate the motion of human arms, the motion of industrial robots, the motion of reptiles and the like, and can be used in various industrial and civil occasions. The design method and the idea of the multi-section pneumatic combined joint are provided for design, manufacture and application of the multi-section pneumatic combined joint, and the multi-section pneumatic combined joint has good application value.
