Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As shown in Figure 1, the 1st, base, the 2nd, column, the 3rd, clip, the 4th, rocking arm, the 5th, model seat, the 6th, model, the 7th, baffle plate, the 8th, jackscrew A, the 9th, jackscrew B, the 10th, jackscrew C, the 11st, section bar, the 12nd, base plate, the 13rd, cubing.

Base 1 connects at base plate by two T type bolts, determines the cubing front-back direction by sliding in T type groove.So just can guarantee that whole cubing is adjustable in the position of X-direction and Y direction.Column 2 is fixed on the base, is the support of whole cubing, and length can be determined according to the degree of bending to of section bar.

Clip 3 is fixed on the column, with the column chucking, plays a supporting role when adjusting the upper-lower position of rocking arm, prevents that rocking arm from falling.

Rocker arm 4 has two kinds of versions, and a kind of pattern is to be mainly used to support model and model seat, can slide up and down along column, is used for determining model position up and down, can just guarantee that model is adjustable on Z-direction, also can rotate around column.Can guarantee that so also model is adjustable around the degree of freedom of Z axle rotation.Another kind of pattern is to be mainly used to support model and model seat, can slide up and down along column, is used for determining model position up and down, can just guarantee that model is adjustable on Z-direction, also can rotate around column.Can guarantee that so also model is adjustable around the degree of freedom of Z axle rotation.This form mainly is used in the place that shape bending is big, coordinate points is concentrated, because it is longer, its base can be installed in the T type groove far away, and can does twice rotation around the Z axle, so just can guarantee that model all the time can be parallel with the normal direction of section bar.

Model seat 5 also has two kinds of versions, and a kind of pattern is to be used for fixing model, can come the model front-back direction is done fine setting by jackscrew 9, and can rotate around rocking arm, guarantees that like this model all can adjust in X-direction with around the degree of freedom that X-axis is rotated.Another kind of pattern is to be used for fixing model, can come fine setting is done in model position up and down by jackscrew 9, but and left rotation and right rotation, so just can guarantee on the Y direction fine-tuning and on Z axle sense of rotation, can adjust.

Model 6 is fixed on the model seat, and can be used for controlling section bar and turn round stubborn angle around the rotation of model seat.So just can guarantee that model is adjustable in the degree of freedom of rotating around Y-axis.The shape of model is removable according to the section material section alteration of form.

By adjusting the coordinate points given coordinate points to the drawing on the cubing model, model is fixed, then the three-dimension curved surface section bar behind the stretch bending is placed on the model, each coordinate points on the section bar is answered coordinate points on the model, make it in desired margin tolerance, thereby control the degree of crook of section bar.The set-up procedure of cubing and detection mode:

This cover cubing in use can not singlely be used, but use by the cubing group that several cubings are formed.

1, at first before adjusting cubing, must there be a standard sections to make model earlier, this standard sections is to try in the stretch bending process at product, compare also the section bar of match fully by scanning of three-dimensional measurement arm and given model, and determine the position of its each coordinate points that need control with the three-dimensional measurement arm measure.

2, then each part is installed, determine the quantity of required cubing, and it is installed in the T type groove of base plate approximate location, do not tighten earlier according to the quantity of the required control coordinate points of section bar.

3, standard sections is placed on the support that is made of the cubing group, and with about each cubing, the position of all around roughly adjusts by the coordinate points on the section bar.

4, section bar is taken away, and then measured coordinate points on each cubing model with the three-dimensional measurement arm, by each micro-adjusting mechanism, the coordinate figure of adjusting each point is consistent with the coordinate figure on the drawing.At last each parts are tightened and fixed, this cubing group just can be used for having detected new product like this.

5, the section bar that will detect is placed on the cubing frame of adjusting as shown in the figure, and the coordinate points on the section bar is overlapped with coordinate points on the corresponding cubing, fixes with the jackscrew on the baffle plate 7 then.

6, each model is used for as control coordinate points place a gap that 2mm is wide being arranged all, and this 2mm is exactly the tolerance value of section bar requirement, after section bar is put well, observe each coordinate points on it, if the A point does not all exceed the outward flange of gap, just prove that this section bar is qualified, otherwise be substandard product just.
