Background

The electric cylinder is a modularized product which integrates a servo motor and a screw rod, converts the rotary motion of the servo motor into linear motion, and simultaneously converts the optimal advantage of the servo motor, namely accurate rotating speed control, accurate torque control into accurate speed control, accurate position control and accurate thrust control; the novel revolutionary product of the high-precision linear motion series is realized, but when the existing electric cylinder piston rod slides out, pollutants such as dust are easy to carry into the electric cylinder or are blocked at the connection point position of the electric cylinder and the piston rod, so that the friction of the piston rod is increased, and the service life of the electric cylinder is reduced.

The Chinese patent publication CN204046342U discloses an electric cylinder, which comprises a servo motor, a roller screw connected with the servo motor and a piston rod connected with the roller screw, wherein trunnions are arranged at the other end of the servo motor and the other end of the piston rod, and a shaft sleeve is arranged on the trunnions. When the electric cylinder is particularly used, the rotary motion of the servo motor can be converted into linear motion, and the electric cylinder has more excellent control performance, is a high-response and long-service-life actuating mechanism, and can effectively prevent the electric cylinder from vibrating in the vibration process by arranging the shaft sleeve on the trunnion. However, this arrangement is easy to reduce the service life of the electric cylinder when the piston rod carries dust into the electric cylinder or blocks the connection port of the electric cylinder, so how to design a damping device for the electric cylinder to solve the problem is a problem that we need to solve currently.
