Common cylinder types, functions and uses

1) Whether the gas pressure from the cylinder piston is one-way or two-way
(1) Single-acting cylinder: The piston of the cylinder can only be pushed by air pressure in one direction, and external force is required when reverse.
(2) Double-acting cylinder: The piston of the cylinder is pushed by air pressure in both positive and negative directions.
2) Classification from the installation form of the cylinder
(1) Fixed cylinder: The cylinder block is fixed.
(2) Axle pin cylinder: The cylinder block can swing around the fixed axle pin at a certain angle.
(3) Rotary cylinder: The cylinder block is usually fixed on the spindle of the machine tool, and can rotate with the spindle of the bed, and this cylinder is often used for pneumatic chucks on the machine tool.
3) Classification from the function and use of the cylinder
(1) Ordinary cylinders: including single-acting and double-acting cylinders. In the absence of special requirements, this type of cylinder is generally used.
(2) Buffer cylinder: The cylinder is equipped with a buffer device to avoid strong impact when the piston moves to the end. This type of cylinder is often used in working places with high pressure and high movement speed.
(3) Pneumatic-hydraulic damping cylinder: the cylinder is connected in series with the hydraulic cylinder to obtain a stable movement speed, and this type of cylinder can be used in occasions with high requirements for speed regulation.
(4) Swing cylinder: The action of the cylinder is used as a reciprocating rotation around the axis, which can be used for fixture indexing, valve switching, etc.
(5) Impact cylinder: It is a high-energy cylinder that forms impact force by high-speed movement of the piston rod, which can be used for stamping, cutting, etc.
