The technical solution adopted in the present invention is as follows:
A kind of concentricity positioning tool method of large-scale component, comprise the second flange, described the second flange becomes unenclosed construction, and the two ends of described the second flange are separately installed with the first flange circle and three-flange dish, and the end face of each flange part is all drawn the cross line of processing; Complete as follows the concentricity frock of the 4th flange and the 5th ring flange:
The first step: be positioned on the end face of the first flange circle, fix a fine rule a isometric with flange loop diameter according to the cross line on the end face of flange circle;
Second step: the mid point of mark fine rule a, some place pulls out a fine rule b therein;
The 3rd step: adopt with method identical in the first step and be positioned at and fix a fine rule c isometric with three-flange dish diameter on the end face of three-flange dish; Meanwhile, the mid point of mark fine rule c, is now connected and fixed the midpoint of the other end of fine rule b and fine rule c;
The 4th step: when the 4th flange is installed, according to the cross line on the 4th flange one end face, fix a fine rule d isometric with the 4th end face of flange diameter, and the mid point of mark fine rule d, mobile the 4th flange, the mid point of fine rule d is contacted with fine rule b, the 4th flange has been located, then by being welded and fixed the 4th flange;
The 5th step: adopt identical method in the 3rd, the 4th step, find out the fine rule e on the 5th ring flange, and the mid point of mark fine rule e, when the 5th ring flange is installed, mobile the 5th ring flange, the mid point of fine rule e is contacted with fine rule b, and the 5th ring flange has been located, then by being welded and fixed the 5th ring flange.
Its further technical scheme is:
Above-mentioned fine rule can adopt cotton thread or single;
In second step, the length of fine rule b is greater than the entire length of required processing work.
Beneficial effect of the present invention is as follows:
The present invention, by the method for many fine rule bracing wires, can find out the concentric position between required installation component easily, and accurately, fast, product percent of pass is high in installation.The present invention does not need to adopt large-scale measurement device just can guarantee the installation of its concentricity requirement, does not more need to provide any special place and professional operating personnel, and cost is low.The present invention is widely used in field work, as during petroleum pipeline welding, water supply pipe welding and main equipment install, using flexibly.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
The present invention is when making the cabin seat of wind-driven generator, as shown in Figure 1, the structure of cabin seat is as follows: comprise open type cone flange 2, one end of cone flange 2 is welded with and coordinates with it flange circle 1, the other end of cone flange 2 welds a ring flange 3, ring flange 3 one side welding cone flanges 4, the end face welding flange 5 of cone flange 4.The cross section of above-mentioned flange arrangement is all greater than semicircle, and before welding, the end face of each flange arrangement has all been drawn cross line.
In actual processing and making process, the two ends of cone flange 2 are welded with respectively flange circle 1 and ring flange 3, complete as follows the installation of cone flange 4 and ring flange 5:
The first step: see Fig. 2, be positioned on the end face of flange circle 1, fix a fine rule a isometric with flange circle 1 diameter according to the cross line on the end face of flange circle 1;
Second step: see Fig. 3, the mid point of mark fine rule a, some place pulls out a fine rule b therein, and the length of fine rule b is greater than the length of whole cabin seat;
The 3rd step: see Fig. 4, adopt with method identical in the first step and be positioned at and fix a fine rule c isometric with ring flange 3 diameters on the end face of ring flange 3; Meanwhile, the mid point of mark fine rule c, is now connected and fixed the midpoint of the other end of fine rule b and fine rule c, and straight line b is by the center of circle of flange circle 1, cone flange 2 and ring flange 3, thereby the center of circle that guarantees their threes point-blank;
The 4th step: see Fig. 5, when cone flange 4 is installed, according to the cross line on cone flange 4 one end faces, fix a fine rule d isometric with cone flange 4 end face diameters, and the mid point of mark fine rule d, mobile cone flange 4, the mid point of fine rule d is contacted with fine rule b, and cone flange 4 has been located, then by being welded and fixed cone flange 4; Guaranteed that the center of circle of cone flange 4 and the center of circle of flange circle 1, cone flange 2 and ring flange 3 are on same straight line;
