Description

TECHNICAL FIELD

[0001] The application relates to the technical field of electric cylinders, in particular to an energy-saving electric cylinder with a damping function. BACKGROUND

[0002] In the field of industrial automation and machinery, a damping electric cylinder plays a key role as an important actuator. It combines the precise control of an electric actuator and the stability of a damping system, and is widely used in various automated equipment and production lines. The damping electric cylinder can be used to control the movement, positioning and assembly of workpieces, ensuring the efficiency and precision of the production process.

[0003] When the end screw drive electric cylinder is in use, the screw is driven to rotate by the motor, and the sleeve and the piston rod are moved by the screw, thereby driving the load to realize linear motion, pushing the processed workpiece. The length of the piston rod is controlled to move the workpiece to the required position. However, in the production environment, dust particles may be present in the production environment. When the piston rod moves out of the cylinder body driven by the screw, the dust particles adhere to the outer wall of the piston rod. When the piston rod retracts, the dust particles are easily carried into the cylinder body along with the piston rod. As the amount of dust particles increases, the cylinder body and the screw are easily blocked. When the sleeve and the piston rod are moved by the screw, the dust will affect the smoothness of the movement of the piston rod. The piston rod moves easily and vibrates, thereby affecting the stability of the electric cylinder pushing the workpiece. SUMMARY
