Cylinder types and principles





What exactly is a cylinder? It converts the pressure energy of compressed air into mechanical energy. The component that drives the mechanism to perform linear reciprocating, swinging and rotating movements is called a cylinder, also called a pneumatic actuator.

The cylinder of the cylinder that performs linear motion can output force, and the cylinder of the swing cylinder and the air motor that performs rotational motion can output torque. Air grippers and vacuum suction cups pick up and place objects.







1. Linear motion cylinder:

Among pneumatic actuators, the most commonly used is the linear motion cylinder. The structure is divided into piston type and non-piston type (such as diaphragm type). The diaphragm type cylinder has good sealing performance, no friction resistance, and no need for lubrication, but the cylinder stroke is short. It is mostly used for clamping and other work in production process control. It is used The most common ones are piston cylinders.

When choosing a piston cylinder, the first thing to do is to confirm the bore and stroke. The larger the bore, the greater the thrust. I will explain how to calculate the output force of the cylinder in a later article. Different installation accessories must also be selected according to the installation environment.


Cylinder working principle: cylinder piston retracts and extends








By adding springs before and after the piston, the cylinder becomes a single-acting cylinder. It only needs one air inlet hole and will automatically reset by spring return when it comes back.









2. Swing and rotate cylinder

The action of rotating the cylinder can be divided into plane rotation and corner pressing of the cylinder. There is a lot to talk about here, and I will share it slowly in subsequent articles.

This rotary model is MSQB rotary cylinder, rack and pinion structure, double cylinder structure, which can display double output.

There is a turntable on it that can be adjusted and rotated from 0-190 degrees. Linear cylinders and finger cylinders can be installed on the upper turntable to complete some simple mechanical actions.






3. Air claw, finger cylinder

As the name suggests, the finger cylinder is a cylinder that functions like a finger. It can grab objects. There are mounting holes on the two clamping jaws. The corresponding clamps can be customized according to different products.







How to choose cylinder type





Classification:
According to cylinder diameter: micro cylinder, small cylinder, medium cylinder, large cylinder
According to buffering form: no buffer cylinder, cushion buffer cylinder, air buffer cylinder
By size: space-saving type, standard type
Cylinder selection:
1. Determine the cylinder diameter - determined according to the load
2. Determine the stroke - based on the range of action
3. Determine the installation method
4. Determine the magnetic switch, etc.
5. Determine the buffer form
6. Determine other accessories
