What types of swing cylinders are there?

Swing cylinder is a kind of cylinder, and there are many types. According to different structural forms, it can be roughly divided into rack-and-pinion swing cylinder, blade swing cylinder and telescopic swing cylinder. The working principle of the oscillating cylinder is similar to that of the ordinary cylinder, that is, compressed air is injected into the rodless cavity of the oscillating cylinder and the inner cavity of the plunger cylinder at the same time, so that the piston rod generates thrust, but the oscillating cylinder has the characteristics of simple structure, convenient use, reasonable layout, safety and reliability, and certain energy-saving effect. Let's learn about the types, principles and characteristics of oscillating cylinders. 1. What types of rotary cylinders are there?

Swing cylinder is a kind of cylinder, which belongs to pneumatic actuator and is used to convert the pressure energy of compressed air into mechanical energy. It can be roughly divided into three types:

1, rack-and-pinion rotary cylinder

Make 1 or 2 cylinders into a whole, make the piston rod into a rack, then make the rotating part into a gear, and set the swing angle by adjusting the screws on it. This kind of swing cylinder has the advantages of large volume and mass, convenient installation of buffer device, large output torque, wide swing angle range and low speed swing.

2. Blade swing cylinder

There are 1 or 2 blades in the cylinder, which are connected with the main shaft. The blade is placed in a closed annular groove. When one side of the annular groove is ventilated, the blade swings to the other side. This kind of cylinder relies on an external stop device to set the angle.

3. Stretch the swing cylinder

That is, telescopic oscillating cylinders, such as two telescopic cylinders, are respectively installed on two symmetrical planes of a rotating shaft, and the rotating shaft is connected with the oscillating cylinder, and the oscillation of the oscillating cylinder drives the two telescopic cylinders to oscillate back and forth within an angle range of 65438+/-080 degrees through the rotating shaft.

Second, the introduction of the working principle of swing cylinder

Swing cylinder includes lock nut, guide sleeve, rear cylinder head, air intake plunger, cylinder body, sealing ring, piston, front cylinder head, etc. When working, because the cross-sectional area of the plunger cavity is very small, the oscillating cylinder consumes little air when it moves rapidly, which will not affect the pressure of the air source. In the slow working stage, compressed air is introduced into the rodless cavity of the oscillating cylinder and the inner cavity of the plunger cylinder at the same time, so that the piston rod generates thrust.

Third, the characteristics of the swing cylinder

1. When the air supply pressure of an ordinary cylinder gradually decreases or stops, the piston rod of the cylinder will slide down; Swing cylinder can't, which greatly improves its working reliability.

2. The invention has the advantages of simple structure, convenient use, reasonable layout, safety and reliability.

3. When the inner diameter of the swing cylinder is large and the idle stroke is long, the swing cylinder has good energy-saving effect.
