Description

Technical Field

[0001] The utility model belongs to the technical field of servo electric cylinders, and more specifically, particularly relates to an explosion-proof servo electric cylinder. Background Art

[0002] At present, the servo electric cylinder is a modular product that integrates the servo motor and the lead screw. It converts the rotary motion of the servo motor into linear motion. It has the characteristics of precise speed and position control, and is therefore widely used in industry. The electric cylinder is generally composed of a motor, a synchronous conveyor belt, a lead screw and a cylinder body, and can be divided into a linear electric cylinder and a reciprocating electric cylinder. In the linear electric cylinder, the motor and the transmission lead screw of the electric cylinder are directly connected, with a compact structure, small inertia and consistent axial direction; the reciprocating electric cylinder has a shorter overall length and is suitable for occasions where the installation position is relatively small.

[0003] The existing servo electric cylinder will generate a lot of heat inside the servo motor and the cylinder body due to the long reciprocating motion time during operation. If the heat cannot be dissipated, the overall operation will be slow, and in severe cases, components will be damaged, affecting the actual operation progress. At the same time, the servo electric cylinder will bring dust into the cylinder body during operation, which is easy to generate static electricity and cause internal components to burn, which is dangerous. It is impossible to monitor the temperature and air pressure changes inside the cylinder body in real time, and it is impossible to adjust and protect the cylinder body in operation in time, which can easily cause damage to the internal structure of the cylinder body and poor overall stability. The reciprocating force of a single screw sleeve is too great, and the pressure cannot be dispersed. Over time, the structure will age and be damaged, greatly reducing its service life.
