Cylinder is a very common pneumatic actuator, but it plays a vital role in automation control system. It is widely used in printing (tension control), semiconductor (spot welding machine, chip grinding), automation control, robot, etc. field.
Its function is to convert the pressure energy of compressed air into mechanical energy, and the drive mechanism performs linear reciprocating motion, swinging and rotating motion.The cylinder is a cylindrical metal part that guides the piston to reciprocate linearly in it. The air converts thermal energy into mechanical energy through expansion in the engine cylinder, and the gas is compressed by the piston in the compressor cylinder to increase the pressure.
1. Single-acting cylinder
There is only one end of the piston rod, air is supplied from one side of the piston to generate air pressure, and the air pressure pushes the piston to generate thrust to extend, and returns by spring or its own weight.
2. Double acting cylinder
Air is staggered from both sides of the piston to deliver force in one or both directions.
3. Rodless cylinder
Generic term for a cylinder without a piston rod. There are two types of magnetic cylinders and cable cylinders.
4. Swing cylinder
The cylinder that does reciprocating swing is called a swing cylinder. The inner cavity is divided into two by the blades, and air is supplied to the two cavities alternately. The output shaft swings, and the swing angle is less than 280°.
The gas-liquid damping cylinder is also called the gas-liquid steady-speed cylinder, which is suitable for the combination that requires the cylinder to move slowly and uniformly. Hydraulic oil is added to the internal structure of the cylinder to achieve the uniform movement of the cylinder.
