The working principle of the rotary swing cylinder mainly involves compressed air driving the output shaft to make reciprocating rotational motion within a certain angle range. This pneumatic actuator is used for the transfer, flipping, classification, clamping of objects, and the opening and closing of valves, etc., especially in automation equipment. The working principle of the rotary swing cylinder can be understood through the following steps: 12
Reset stage: Introduce air pressure (0.1-0.8MPa) from port B, and exhaust the atmosphere from port A at the same time, and the piston and piston rod retreat backward. When the piston hits the right end of the cylinder body, it stops, and the piston rod end is at point a. This state is the reset state.
Working stage: Introduce air pressure (0.1-0.8MPa) from port A, and exhaust the atmosphere from port B at the same time, and the piston rod and piston extend forward. When the piston hits the front cover, it stops moving. At this time, the piston rod end is at point b, and the distance between a and b is the piston stroke S. This state is the working state of the rotary cylinder.
Cyclic work: By repeating the above steps, the cylinder body rotates, and the piston and the piston rod move back and forth, thereby realizing continuous rotation and swinging motion.
The design parameters of the rotary swing cylinder include swing angle, swing starting point, switch form, number of switches and options, etc. The selection of these parameters directly affects the specific application and performance of the cylinder. Due to its wide range of applications, such as robot arm movements, valve opening and closing, etc., the rotary swing cylinder plays an important role in the field of automation and machinery.
