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.

Description
Technical field
The present invention relates to a kind of cantilever frame for movement amount of deflection control method, cantilever frame for movement can be adjusted using the present invention
Deflection deformation, change cantilever frame for movement natural bow value, meet cantilever frame for movement physics morpheme size require.
Background technology
In some engineer applied fields, often use large scale cantilever frame for movement.Due to being made by gravity and other external force
With cantilever frame for movement can produce compared with Large deflection it is impossible to reach the linearity index of engine request.At present.Engineering construction
During frequently with increase cantilever frame for movement rigidity method, by from high rigidity, low-density material, subtracting as far as possible
The amount of deflection of few cantilever frame for movement, is required with the physics morpheme size meeting cantilever frame for movement.But, for some large scales
Cantilever frame for movement, after taking said method, the linearity that still can not meet cantilever frame for movement requires.Often adopt at present
With single taperliner, cantilever frame for movement is adjusted.Cantilever frame for movement segmentation manufactures, and is carried out using flange between each section
Connect, between flange, adjust the original shape of cantilever frame for movement using single taperliner, by adjusting, cantilever frame for movement
Original shape be the broken line being upturned, in the presence of the making a concerted effort of gravity and other external force, cantilever frame for movement is tilted upward
The distance rising can be compensated with its amount of deflection, by the taperliner using proper angle, so that each flange connections is located just at
In same horizontal line, thus reaching linearity index.But, single taperliner adjusts the essence that method extremely relies on taperliner angle
Really calculate and Precision Machining, each taperliner angle is different and processes and cannot be carried out Secondary Control after installing, and can only pass through
The adjusting gasket of the different angles of replacing can be only achieved expected linearity and requires repeatedly.
Content of the invention
In order to overcome single taperliner reconcile method excessively rely on the accurate calculating of taperliner angle and Precision Machining and
Need to change the shortcoming that pad just can carry out Secondary Control, the present invention provides a kind of cantilever frame for movement amount of deflection control method.
The cantilever frame for movement amount of deflection control method of the present invention, in turn includes the following steps：
A. calculate the regulation angle determining double-wedge pad adjustment mechanism；
B. double-wedge pad is arranged between the adpting flange of cantilever frame for movement；
C. measure the amount of deflection at cantilever frame for movement each adpting flange center, start cantilever frame for movement is carried out from cantilever end
Adjust again；
D., when adpting flange is centrally located at below horizontal line, the taperliner rotating at previous adpting flange is double to increase
The regulation angle of taperliner governor motion, makes adpting flange center move up；
E., when adpting flange is centrally located above the horizon, at the previous adpting flange of rotation, taperliner is to reduce folding wedge
The regulation angle of shape pad adjustment mechanism, makes adpting flange center move down；
F. by this regulation repeatedly until by this adpting flange center adjustment to horizontal line on, reach cantilever machinery knot
The linearity of structure requires.
By two pieces of identical taperliners, connection combines described double-wedge pad adjustment mechanism back-to-back.
Described regulation angle is.
The technical solution adopted for the present invention to solve the technical problems is：Two panels identical taperliner combines back-to-back,
When its I, III rudder face line is all vertical and direction is identical, adjusts angle maximum, be the twice of monolithic taperliner angle；When it
The equal level of I, III rudder face line and in opposite direction when, adjust angle be 0.By rotary wedge pad, double-wedge pad can be made to adjust
The regulation angle of section mechanism consecutive variations between 0 degree to 2 times taperliner inclination angle.Cantilever frame for movement segmentation manufactures, respectively
It is attached by adpting flange between section, between flange, angular adjustment is carried out by double-wedge pad adjustment mechanism.According to outstanding
Version, the density of adopted material and elastic modelling quantity after the installation of arm frame for movement, calculates its sag curve, Ran Hougen
Calculate the double-wedge pad that each adpting flange center adjustment to same horizontal line is needed according to the amount of deflection at each adpting flange center
The regulation angle of governor motion, and then determine the anglec of rotation of pad.According to this theoretical calculation regulation angle value to cantilever machine
Tool structure is assembled.After completing the assembling of cantilever frame for movement, start to measure the position at each adpting flange center from cantilever end,
If adpting flange center, needs to change the tune of double-wedge pad adjustment mechanism according to measurement result not in the same horizontal line
Section angle, is adjusted again to cantilever frame for movement.When adpting flange is centrally located at below horizontal line, rotate previous connection
The taperliner of flange, to increase the regulation angle of double-wedge pad adjustment mechanism, makes adpting flange center move up；When
When adpting flange is centrally located above the horizon, rotates taperliner at previous adpting flange and adjust machine to reduce double-wedge pad
The regulation angle of structure, makes adpting flange center move down.By this regulation repeatedly until adjusting this adpting flange center
Save on horizontal line.It is adjusted to far-end from cantilever end successively, until the center of all of adpting flange is respectively positioned on same water
On horizontal line, the linearity reaching cantilever frame for movement requires.
The invention has the beneficial effects as follows, it is possible to use the double-wedge pad of two panels identical taperliner composition adjusts machine
Structure, by the rotation of taperliner, realizes a range of continuously adjusting angle.First with the regulation angle of theoretical calculation to outstanding
The amount of deflection of arm frame for movement is tentatively adjusted, the position at each adpting flange center then being obtained according to measurement, rotary wedge
Pad changes the regulation angle of double-wedge pad adjustment mechanism, and cantilever frame for movement is adjusted repeatedly, until by each connection
Flange center is adjusted in same horizontal line, reaches expected linearity requirement.
