How to use self-locking cylinder, working principle of self-locking cylinder

Working principle of self-locking cylinder

This kind of cylinder is used for safety. At the front or rear end of the cylinder, there is a wedge-shaped column structure, which introduces a line of compressed air. When the cylinder is running, the stuck column is stretched Open without affecting the operation. After the air source is cut off, the clamping column retracts and the piston rod is held tightly by the spring force. Due to the wedge-shaped structure, it can prevent movement in one direction (not in the reverse direction)

Another method is to install a pin that extends into the piston rod slot to prevent it from moving. This structure is not very reliable.

How to use a self-locking cylinder

The self-locking switch is also a common push button switch. The difference is that when the self-locking switch is pressed, it will maintain a state, either in the on state or in the off state. Keep.

Using its advantages, you can save button switches and intermediate relays. Use push-button switches, at least two push-button switches, one for energizing the solenoid valve and one for de-energizing the solenoid valve, and the button for energizing the solenoid valve also needs a switch Connect in parallel with the normally open contact of the intermediate relay to form a self-locking.

Use the self-locking switch mentioned in the title, connect it directly to the solenoid valve, and then connect the solenoid valve to the air source hose and lead it to the cylinder. It is a very simple control circuit, consisting of a 24V power module, self-locking switch and solenoid valvea control loop, and then connect the cylinder with the air source hose< span style="color:#003399;">Solenoid valve Just connect it, power on the 24V module and press the self-locking switch to realize the up and down movement of the cylinder.

The self-locking switch can be used in one standby and one in use to prevent the working self-locking switch from being broken and making it impossible to manually control the cylinder. In addition, the air source pressure is generally 1MPa. The actual situation may require the cylinder to run faster or slower. At this time, install a cylinder at the air source inlet. Air filter pressure reducing valve, which can adjust the pressure from 0 to 1MPa. Normally, 0.4 MPa pressure is enough to meet the operation of the cylinder.
