Problems solved by technology

[0008] With the development of high-performance military equipment and the rapid development of the civilian market, the requirements for various indicators of linear electromechanical actuators are becoming more and more stringent, and the shortcomings of existing structural forms are more obvious. Rigid and high load-bearing electromechanical actuators have become the direction of future technology research and development, so it is necessary to invent a highly integrated electromechanical actuator to meet future development needs

Embodiment Construction

[0032] like Figure 1-7 As shown, the structural components of the present invention are composed of: long nut rotor assembly, servo motor stator assembly, rotor support and fixation assembly, screw actuating rod assembly, actuating rod support and fixing assembly, angular velocity sensor assembly, linear displacement sensor assembly, front end Lug connection components, back-end lug connection components, etc.

[0033] One end of the screw actuating rod assembly is installed with the front lug connection assembly, and the other end is matched with the long nut rotor assembly. When the long nut rotor assembly rotates at a fixed axis, the screw actuating rod assembly makes a reciprocating linear motion, and the long nut rotor assembly The outside is connected to the servo motor stator assembly through the rotor support and fixing assembly. The angular velocity sensor assembly is installed on the long nut rotor assembly to detect the angular velocity of the motor rotor. The line...

Abstract

The invention discloses a highly integrated electromechanical actuator. One end of a screw actuating rod assembly is provided with a front end support lug connection assembly, and the other end of the screw actuating rod assembly is provided with a long nut rotor assembly for cooperation. When the long nut rotor assembly performs the fixed-axis rotation, the screw actuating rod assembly makes reciprocating rectilinear movement. The exterior of the long nut rotor assembly is connected with a servo motor stator assembly through a rotor support fixing assembly. An angular velocity sensor assembly is installed on the long nut rotor assembly, and is used for detecting the angular velocity of a motor rotor. A linear displacement sensor assembly is installed on the screw actuating rod assembly and an actuating rod support fixing assembly which is used for providing a support and fixing effect for the installation of the screw actuating rod assembly, and is used for detecting the displacement information of an actuating rod. A rear end support lug connection assembly is connected with the servo motor stator assembly, and is used for bearing an axial tensioning and pressing load, and preventing the electromechanical actuator from rotating in the peripheral direction. The front end support lug connection assembly and the rear end support lug connection assembly are respectively connected with an external device mechanical interface.

Description

technical field [0001] The invention belongs to the technical field of electromechanical servo, and in particular relates to a highly integrated electromechanical actuator with integrated design. Background technique [0002] An electromechanical actuator is a device that converts electrical energy into mechanical energy and realizes motion conversion. Compared with hydraulic and pneumatic actuators, it has the advantages of small size, light weight, compact structure, high dynamic response, high control precision, and easy maintenance. Convenience and other characteristics, it is used in aerospace, navigation, transportation, large-scale robots, construction machinery, agricultural machinery and other fields. It has broad prospects and is one of the important research directions for the development of servo technology in the future. [0003] The electromechanical actuator converts the electrical signal output by the controller into mechanical quantities such as strain, disp...
