Connection method and connection structure of resultant force point double lugs and lever load transfer system

Abstract

The invention discloses a connection method and a connection structure of resultant force point double lugs and a lever load transfer system, and the method comprises the following steps: punching a round hole at the resultant force point position of a last-stage lever as a resultant force point through hole, processing a resultant force point steel ring, and punching and fixing the steel ring in the resultant force point through hole; two round holes are formed in two lugs of the double-lug connecting piece to serve as connecting holes, two linings are machined, and the two linings are inserted into the two lugs and the conical through hole of the steel ring from the two sides of the double-lug connecting piece respectively. The two bushings can be in tight fit connection with the conical through hole in the resultant force point steel ring and the round hole in the double-lug connecting piece. According to the technical scheme, the problem that for a lever loading system in a hard connection mode, the elongation of a piston rod of an actuator cylinder is difficult to control, and connection points are all of a tight fit connection structure, so that the implementation of point connection of an existing hard connection method is difficult is solved.

Description

technical field [0001] The present invention relates to but not limited to the technical field of the connection form of binaural and lever load transmission, and in particular relates to a connection method and connection structure of the double lug of the resultant force point and the lever load transmission system. Background technique [0002] In the ground verification test of aircraft structural strength, it is usually necessary to use a lever loading system to apply load to the test piece. [0003] The structural forms of the current lever loading system mainly include: adhesive tape-lever, tension pad-lever and shear block-lever. The load applied to the test piece is completed by loading the actuator, the force sensor, the connecting piece and the lever loading system; therefore, it is necessary to connect the connecting piece and the resultant force point of the lever loading system before the test. Before connecting the points, connect the connecting piece with th...

Problems solved by technology

[0005] The purpose of the embodiment of the present invention is: the embodiment of the present invention provides a connection method and connection structure between the two lugs of the resultant force point and the lever load transmission system, so as to solve the problem that it is difficult to control the lever load system in the form of hard connection by using the existing point connection method The elongation of the piston rod of the actuator, and because the connection points are tight-fit connection structures, it is difficult to implement the existing hard connection method when connecting points
