Problems solved by technology

Although this flexible cylinder realizes the curved operation of the flexible cylinder body and the sliding table, the cylinder piston uses a spherical magnet, the magnetic coupling with the magnet of the matching sliding table is small, and the magnetic force generated between the magnets is relatively small. The rubber layer is

Abstract

The invention discloses a novel flexible air-magnetic drive actuator. The novel flexible air-magnetic drive actuator comprises a flexible air cylinder, an air cylinder sliding table and multiple cylinder shape fixing devices. The flexible air cylinder comprises a flexible air cylinder body and an air cylinder piston arranged in the flexible air cylinder body, the air cylinder piston comprises a piston sleeve, a piston seal ring and a piston inner magnet, the piston seal ring is arranged outside the piston sleeve and is in contact with the inner wall face of the flexible air cylinder body, theair cylinder sliding table comprises a sliding table body, multiple balls and an outer magnet, the sliding table body is arranged outside the flexible air cylinder body, the outer magnet is clamped between the sliding table body and the outer surface of the flexible air cylinder body, the balls are located in a ball groove of the sliding table body and is in contact with the outer surface of the flexible air cylinder body, and an equipment mounting hole is formed in the lower portion of the sliding table body. Through cooperation of the cylinder shape fixing devices, the air cylinder shape ischanged into the needed cylinder shape, the air pressure transmission and magnetic force effect is applied, and through the changes of the flexible air cylinder body shape, motion of an end actuator on the different curve tracks can be achieved.

Description

technical field [0001] The invention belongs to the field of pneumatic transmission, in particular to a novel flexible aeromagnetic drive actuator. Background technique [0002] At present, in the field of point-to-point material transportation in industrial production, pneumatic electric actuators are widely used. The most used pneumatic actuators are linear cylinders and swing cylinders, which can drive the load to move on a straight line and a circular arc track. In some applications Occasionally, it is necessary for the actuator to realize a non-circular and non-linear motion track. For example, in the scene of industrial manipulator gluing, the gluing track has a certain arc. At present, such track motion is realized in industry by using stepping motor and electric actuator cylinder to align the arc. The fitting of the line realizes such trajectory movement. However, at present, the cost of the mechanism for realizing such an action is relatively high, and the complexi...
