The solution of the deflection angle of tooling unit module being obliquely installed in the step S2 about acquisition, specific implementation
For：
Setting supporting rod in each tooling module, at a distance of l, the elemental height of supporting rod is h.
To matched curve f (x) derivations, f ' (x)=0 is enabled, acquires x0Point (i.e. stationary point), with x0Coordinate is established for coordinate origin
System, then form new curvilinear equation, g (x)=f (x-x at this time0)
In x0Lower section Δ h2One is done perpendicular to x=x in place0And the line segment that length is L, line segment two-end-point are denoted as A, B points, directly
Line L is by straight line x=x0Divide equally.By the AB quarterings, then by 3 points of straight lines done perpendicular to the line segment among AB line segments, hand over respectively

2 points of d ' is 2 points of L, line ac ' and bd '；Then from A, 2 points of B makees length as L and is parallel to ac ' and bd respectively ' line
Section, note terminal is respectively C, D.
Then by rightmost endpoint in 3 points among CD line segments (for this sentences X-axis right axle shaft, if the reconnaissance of left half axle institute should
It is Far Left endpoint in 3 points among line segment) straight line perpendicular to the line segment is done, curve g (x) and d points are handed over respectively, then again with d
For basic point, both sides extended spot finds out the f ' points that distance d points are L respectively on curve, and 2 points of line is into line segment df '；Then from D points
Make length respectively as L and be parallel to the line segment of line segment df ', note terminal is F.And so on, until End of Curve section.Finally do

B point coordinates should be (x1=L/4, g (x1)), d ' point coordinates is (x2, g (x2)), f ' point coordinates is (x3, g (x3)), according to
It is secondary to analogize, have：
(x2-x1)2+(g(x2)-g(x1))2=L2；
It can then obtain：
First deflection angle of tooling unit module being obliquely installed can be obtained；
On this basis, it is as follows to the deflection angle expression formula of arbitrary tooling unit module：
(xn+1-xn)2+(g(xn+1)-g(xn))2=L2；
The method that supporting rod lifting height is determined in the step S3, is embodied as：
If Δ h2For one be not 0 constant (Δ h2＞ h), by taking x right axle shafts as an example, B point coordinates is (L/2 ,-Δ h2), and
The deflection angle of each tooling unit module can be obtained from the above analysis, then the tooling unit module that the right first is obliquely installed can be written
Analytical expression be：
Similar method calculates other tooling unit modules, and the starting point coordinate of n-th of tooling unit module is (xn, g
(xn)-Δh2), and the deflection angle of the tooling unit module is αn, then the analytical expression of n-th of tooling unit module be：
yn=tan αn(x-xn)+Δh2-g(xn)
Since basic tooling unit module is horizontal positioned, the lifting height of each supporting rod is respectively Δ h2,It is increased on the supporting rod of remaining each tooling unit module (the tooling unit module being obliquely installed)
Degree, from the above equation, we can see that, it is known that corresponding tooling unit module structure deflection angle (being referred to as angle of inclination), therefore can obtain and this
The orthogonal linear equation of straight line, expression formula are：
Wherein enableIt can obtain
The linear equation of each tooling unit module upper support bar, i.e. lifting height expression formula.
