A device for an actuator that does not change the direction of the lug and realizes stepless adjustment of the zero length

Abstract

Disclosed is an apparatus for an actuator without changing supporting lug direction and capable of realizing stepless regulation zero length. The apparatus is mounted between a front supporting lug and a screw rod end plane, and tight locking of the apparatus is realized through a thick nut I (2), a thin nut I (3), a thick nut II (5) and a thin nut II (6); a blind hole is formed in one end with afirst cylindrical section; a through hole which is smaller than two times of the screw thread small diameter is drilled to reduce the weight; left rotation inner screw threads are arranged in the blind hole; right rotation outer screw threads are arranged on the outer side of a second cylindrical section; the left rotation inner screw threads and the right rotation outer screw threads are roughlyconsistent; the screw pitch between the screw threads at the two ends is the same as that of the front supporting lug and the screw rod and is equal to 1mm; and in adjustment, the forward and backwardrotation of the thick nut I (2), the thin nut I (3), the thick nut II (5) and the thin nut II (6) are loosened, so that the apparatus can realize stepless regulation zero length installation of the actuator within a certain range.

Description

technical field [0001] The invention relates to a device for an actuator that does not change the direction of lugs and realizes stepless adjustment of the zero-position length, and is especially suitable for the technical field of precise zero-position adjustment of electromechanical actuators. Background technique [0002] The electromechanical actuator has its very prominent advantages, so the development speed is fast, and the application is also expanding rapidly, which makes the electromechanical actuator have more and more stringent requirements for its zero position in practical applications. [0003] The installation zero position of the electromechanical actuator is used to determine the initial position of each airfoil, but in most cases the installation zero position of the electromechanical actuator is not a whole millimeter, it will be a tenth of a millimeter or a hundredth of a millimeter, or even more Precise; the previous actuators could not achieve fine adj...
