Brief introduction of single acting fork type pneumatic actuator
Provide air cylinder and box fork pneumatic actuator, including air cylinder, box, spring cylinder, piston, piston rod and spring seat; The left end of the piston rod is connected with the right end of the spring cylinder; The left end of the compression spring is connected with the coaxial sleeve at the right end of the left spring seat; Axial center of left spring seat rotates axially to install adjusting bolt and adjust left limit position; The split rotation of the axisymmetric structure is driven by a pin shaft in the middle of the piston rod rod; The output torque of the transmission shaft is fixed by the locating pin at the upper end of the fork; Both ends of the transmission shaft are installed on the rotating support of the box through an axisymmetric shaft sleeve; The inner wall of the cylinder block is provided with PTFE coating The utility model has the advantages of simple structure, compact design and small volume; Modular assembly, easy to process and operate; Fast response, stable, reliable and efficient transmission; It can realize large torque output and has comprehensive advantages of economy, practicality and high cost performance
The utility model discloses a single function bifurcated pneumatic actuator, which comprises a cylinder module; The cylinder module comprises a connecting cover, a through hole and a side wall of the connecting box module; Piston rod, connecting box module, through through hole; The sealing element is connected to the through hole and matched with the outer circle of the piston rod; The cylinder block comprises a half cylinder block, a second half cylinder block and a second sealing element; The half cylinder block and the second half cylinder block have the same structure and are combined to form a circular inner cavity; The cylinder head is connected to the cylinder block and is arranged at both ends of the cylinder block opposite to the connecting head; The third sealing element is respectively arranged between the connecting cover and the cylinder block, or between the cylinder head and the cylinder block; The piston is connected to one end of the piston rod and can move back and forth with the piston rod in the inner cavity by matching with the inner wall of the cylinder; To overcome the technical problems of poor reliability of cylinder module structure, inconvenient installation and disassembly, and relatively large structure weight
