What can ordinary cylinders be divided into according to their working principles?

Among pneumatic actuators, linear motion cylinder is the most widely used. Structure is divided into piston type and non-piston type (such as diaphragm type). Diaphragm cylinder has good sealing performance, no friction resistance and no lubrication, but the cylinder stroke is short, which is mostly used for clamping and other work in production process control, and piston cylinder is the most used.

When choosing a piston cylinder, the cylinder diameter and stroke should be determined first. The larger the cylinder diameter, the greater the thrust. I will explain how to calculate the output force of the cylinder in a later article and choose different installation accessories according to the installation environment.

Piston cylinder

The working principle of the cylinder: the piston of the cylinder retracts and extends.

Cylinder piston retraction

Cylinder piston extension

By adding springs before and after the piston, the cylinder becomes a single-acting cylinder, which only needs an air inlet and will automatically reset when it comes back.

2. Swing and rotate the cylinder

The action of rotating cylinder can be divided into plane rotation and angle pressing cylinder. There are many things to talk about here, and I will share them slowly in later articles.

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

There is a turntable on it, which can adjust the rotation by 0- 190 degrees. A linear cylinder and a finger cylinder can be installed on the upper turntable, which can complete some simple mechanical actions.

3, air claw, finger cylinder

As the name implies, the finger cylinder is a cylinder with the same function as the finger, which can grab objects. The two clamping jaws are provided with mounting holes, and corresponding fixtures can be customized according to different products.
