Abstract

The invention provides a manual and automatic clutch structure of a pneumatic actuator. The manual and automatic clutch structure comprises a pneumatic actuator body, a speed reducer mechanism and a manual and automatic clutch mechanism arranged between the pneumatic actuator body and the speed reducer mechanism, wherein the pneumatic actuator body comprises an output shaft; the speed reducer mechanism comprises an input shaft and a box cover; and the manual and automatic clutch mechanism comprises a sliding sleeve and a toggling unit, wherein the toggling unit comprises a rotating shaft and a locating pin, the rotating shaft is arranged in a through hole of the box cover, the locating pin is arranged at the end, facing to the input shaft, of the rotating shaft, the central line of the locating pin is deviated from the central line of the rotating shaft, and the top of the locating pin is arranged in a locating slot formed in the outer surface of the sliding sleeve. According to the manual and automatic clutch structure of the pneumatic actuator, provided by the invention, the arrangement of the sliding sleeve decides the connection and disconnection of the pneumatic actuator body and the speed reducer mechanism, and furthermore manual and automatic working states are kept between the pneumatic actuator body and the speed reducer mechanism; and due to the adoption of the design, operation difficulty caused by overlarge torque cannot be generated when manual operation is adopted, so that the physical power is saved.

Description

technical field [0001] The invention belongs to the field of pneumatic equipment, in particular to a manual automatic clutch structure of a pneumatic actuator. Background technique [0002] The working principle of the pneumatic actuator is that the air source pressure enters the middle chamber between the two pistons of the cylinder from the air port, forcing the springs at both ends to compress, and the air in the air chambers at both ends is discharged through the air port, and at the same time, the two piston racks drive the output shaft to rotate synchronously (90 °, 120°), after the air source pressure is reversed by the solenoid valve, the two pistons of the cylinder move to the middle direction under the action of the spring force, and the air in the middle cylinder is discharged from the air port, and at the same time, the two piston racks drive the output shaft to reverse Direction rotation, forward and reverse rotation of the output shaft to achieve the purpose of...
