Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a controller of an electric actuator. Background Art

[0002] An electric actuator is a device that can convert electrical energy into mechanical energy. It can achieve linear or rotational motion through the drive of an electric motor. Electric actuators are widely used in automated control systems, such as industrial production lines, robots, medical equipment, and other fields.

[0003] During the use of the electric actuator, it is usually necessary to control the electric actuator through the controller of the electric actuator. When the controller of the electric actuator is working, the controller of the electric actuator usually transmits the received data to the control device in real time through the data interface. After the control device processes, the control signal of the control device to the electric actuator is transmitted to the electric actuator through the data interface, thereby regulating the operation status of the electric actuator.

[0004] During use, the controller of the existing electric actuator is usually installed and fixed by tightening screws, but the operation is cumbersome and reduces the installation efficiency. The controller of some electric actuators drives the limit plate to rotate through a torsion spring, thereby limiting and fixing the controller of the electric actuator, thereby replacing the bolt connection. However, after long-term use, the elastic performance of the torsion spring weakens, which can easily cause the controller of the electric actuator to fall off, reducing the stability of the controller of the electric actuator. For this reason, we propose a controller for an electric actuator. Utility Model Content

[0032] The working principle of the controller of an electric actuator provided by the utility model is as follows: before use, the controller of the electric actuator is moved to a designated work location, so that the rear end of the housing 1 contacts the corresponding work station, and then the servo motor 5 starts to run through the regulation of the single chip microcomputer 2, and the output shaft of the servo motor 5 drives the output rod 46 to rotate, and the output rod 46 drives the worm 47 to rotate, and the worm 47 drives the worm wheel 45 to rotate through the meshing connection, and the worm wheel 45 drives the cross bar 44 to rotate, and the cross bar 44 drives the installation rod 41 to rotate through the transmission connection between the pulleys 43, so that the installation rod 41 drives the limit plate 42 Rotation, since the two worm gears 47 rotate in opposite directions, the distance between the two limit plates 42 is gradually reduced, and finally the limit plates 42 are tightly attached to the outer surface of the corresponding workstation through the rubber pads 7, thereby realizing the installation and fixation of the controller of the electric actuator. In the subsequent work process, the data interface 6 receives the control signal of the external control center, and then the data interface 6 transmits the received data to the single-chip microcomputer 2 in real time.
