Connecting device for electromechanical actuator and engine

Abstract

The invention discloses a connecting device for an electromechanical actuator and an engine, and particularly relates to the technical field of actuators. The connecting device comprises an actuator mounting disc, a mounting seat is fixedly arranged at the top of the actuator mounting disc, and actuator supporting lugs are fixedly arranged on the two sides of the top of the mounting seat; and a joint shaft is fixedly arranged between the middles of the two actuator supporting lugs, engine supporting lugs are arranged in the two actuator supporting lugs and connected with the joint shaft in a matched and sleeved mode, and a limiting base plate is arranged on one sides of the two actuator supporting lugs. A pushing bolt drives an extrusion block to press an extrusion base and a lifting column to descend, the rotation angle of the limiting base plate is adjusted, the rotation range of the engine supporting lugs is blocked and limited, the requirement for a swing spraying pipe of the electromechanical actuator can be met, the movement angle between the actuator supporting lugs and the engine supporting lugs is limited through a limiting gear, adjustment is convenient, and the connecting device is convenient to use.

Description

technical field [0001] The invention relates to the technical field of actuators, in particular to a connection device between an electromechanical actuator and an engine. Background technique [0002] Actuator is a key component to implement active vibration control and an important part of active control system. The role of the actuator is to exert control force on the control object according to the determined control law. With the development of active vibration control technology, the requirements for actuators are getting higher and higher. The anti-roll structures used in existing products are "cross shaft" and cross lug structures. Although these two solutions can achieve full The requirement for the degrees of freedom of the lugs required for the thrust vector control of the axial swing nozzle, that is, the degree of freedom of the electromechanical actuator to rotate along its own axis when the electromechanical actuator swings in the two directions of pitch and y...

AI Technical Summary

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides a connection device between an electromechanical actuator and an engine. By pushing the bolt, the extrusion block is driven, the extrusion seat is pressed, the lifting column is pressed down, and the rotation angle of the limiting backing plate is adjusted to adjust the rotation angle of the engine lug. The rotation range is blocked and limited, and the push bolt is then reversed to drive the extrusion block to shrink, and the return spring is used to push the extrusion seat to restore the engagement and fixation of the limit block to the limit gear, which can meet the swing nozzle of the electromechanical actuator. , the movable angle between the actuator lug and the engine lug is limited by limiting the gear, the adjustment is convenient, and the use of the connecting device is convenient, so as to solve the inconvenient limitation of the swing range of the electromechanical actuator in the prior art, Problems affecting the use of electromechanical actuators and engines
