Description

[Technical field]

[0001] The utility model relates to the technical field of cylinders, in particular to a cylinder with a rotation function. [Background technology]

[0002] The rotary cylinder is a pneumatically driven rotary actuator, which is widely used in various industrial automation equipment. It has the characteristics of simple structure, sensitive action and easy operation. It can replace the traditional electric actuator and has great advantages in saving energy and improving efficiency.

[0003] The air intake and exhaust control of the rotary cylinder is realized by the solenoid valve. When the battery valve is energized, the air inlet opens, and the compressed air enters the cylinder to push the piston to rotate; when the battery valve is de-energized, the exhaust port opens, and the compressed air is discharged from the cylinder, and the piston stops rotating. By controlling the power-on time and the on-off state of the battery valve, the rotation angle, rotation speed and rotation direction of the cylinder can be controlled.

[0004] However, in the existing rotary cylinder, the piston will also rotate during its use. After a long period of work, the piston will become loose, affecting the normal use of the cylinder and thus reducing the service life of the cylinder.

[0005] In view of this, the utility model provides a cylinder with rotational energy, which aims to prevent the piston from rotating during use, thereby preventing normal use from being affected, thereby increasing the service life of the cylinder. [Contents of the utility model]
