A method for adjusting the deflection of a cantilever mechanical structure

Abstract

The invention provides a method for adjusting deflexion of a cantilever mechanical structure. The method includes the following steps in sequence: calculating to determine the adjusting angle of a double-wedge gasket adjusting mechanism; mounting the double-wedge gasket between connecting flanges of the cantilever mechanical structure; measuring the deflexion of the centers of all connecting flanges of the cantilever mechanical structure, and adjusting the cantilever mechanical structure from the cantilever end again; adjusting the center of the connecting flange: if the center of a connecting flange is below the horizontal line, rotating the wedge-shaped gasket at the position of the previous connecting flange, so as to enlarge the adjusting angle of the double-wedge gasket adjusting mechanism and enable the center of the connecting flange to move upwards, and if the center of a connecting flange is above the horizontal line, rotating the wedge-shaped gasket at the position of the previous connecting flange, so as to reduce the adjusting angle of the double-wedge gasket adjusting mechanism and enable the center of the connecting flange to move downwards. The center of the connecting flange is repeatedly adjusted until the center reaches the horizontal line and meets the straightness requirements of the cantilever mechanical structure. The adjusting method provided by the invention is easy to operate and high in accuracy of adjustment.

Description

technical field

[0001] The invention relates to a method for adjusting the deflection of a cantilever mechanical structure. By adopting the method, the deflection deformation of the cantilever mechanical structure can be adjusted, the natural deflection value of the cantilever mechanical structure can be changed, and the physical shape, position and size requirements of the cantilever mechanical structure can be met. Background technique

[0002] In some engineering application fields, large-scale cantilever mechanical structures are often used. Due to the action of gravity and other external forces, the cantilever mechanical structure will produce large deflection deformation, which cannot meet the straightness index required by the project. Currently. In the process of project implementation, the method of increasing the rigidity of the cantilever mechanical structure is often used. By selecting high-rigidity and low-density materials, the deflection of the cantilever mec...

With the outer normal of the circular surface passing through the center of the circular surface as the axis of rotation, both gaskets rotate counterclockwise, and the adjustment angle of the double-wedge gasket adjusting mechanism will become smaller. When both gaskets are rotated 90 degrees, the adjustment angle of the double-wedge gasket adjustment mechanism is 0 deg...
