The technical scheme that the present invention adopted is following:
A kind of concentricity positioning tool method of large-scale component; Comprise second flange; Said second flange becomes unenclosed construction, and the two ends of said second flange are separately installed with the first flange circle and the 3rd ring flange, and the end face of each flange part is all drawn the cross line of processing; Accomplish the concentricity frock of the 4th flange and the 5th ring flange through following steps:
The first step: be positioned on the end face of the first flange circle, according to the fixing fine rule a isometric of the line of the cross on the end face of flange circle with the flange loop diameter;
Second step: the mid point of mark fine rule a, the some place pulls out a fine rule b therein;
The 3rd step: adopt with the first step in identical method be positioned on the end face of the 3rd ring flange and fix a fine rule c isometric with the 3rd ring flange diameter; Simultaneously, the mid point of mark fine rule c, this moment, the other end with fine rule b was connected fixing with the midpoint of fine rule c;
The 4th step: when the 4th flange is installed; According to the fixing fine rule d isometric of the line of the cross on the 4th flange one end face with the 4th end face of flange diameter; And the mid point of mark fine rule d, move the 4th flange, the mid point of fine rule d is contacted with fine rule b; Then accomplish the 4th flange location, then through fixing the 4th flange of welding;
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; Move the 5th ring flange; The mid point of fine rule e is contacted with fine rule b, and then accomplish the 5th ring flange location, then through fixing the 5th ring flange of welding.
Its further technical scheme is:
Above-mentioned fine rule can adopt cotton thread or single;
The length of fine rule b is greater than the entire length of required processing work in second step.
Beneficial effect of the present invention is following:
The present invention can find out the concentric position between the required installation component easily through the method for many fine rule backguys, and it is accurate, quick to install, and product percent of pass is high.The present invention need not adopt large-scale measurement device just can guarantee the installation of its concentricity requirement, and any special place and the operating personnel of specialty more need be provided, and cost is low.The present invention uses flexibly in being widely used in the field work installing like petroleum pipeline welding, water supply pipe welding and main equipment.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
When the present invention is used for making the cabin seat of wind-driven generator; As shown in Figure 1; The structure of cabin seat is following: comprise open type cone flange 2, an end of cone flange 2 is welded with and cooperates flange circle 1 with it, and the other end of cone flange 2 welds a ring flange 3; Ring flange 3 one face down bondings connect cone flange 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 the end face of each flange arrangement has all been drawn the cross line before welding.
In the actual processing and making process, the two ends of cone flange 2 are welded with flange circle 1 and ring flange 3 respectively, accomplish the installation of cone flange 4 and ring flange 5 through following steps:
The first step: see Fig. 2, be positioned on the end face of flange circle 1, according to the fixing fine rule a isometric of the line of the cross on the end face of flange circle 1 with flange circle 1 diameter;
Second step: see Fig. 3, the mid point of mark fine rule a, the 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 the first step in identical method be positioned on the end face of ring flange 3 and fix a fine rule c isometric with ring flange 3 diameters; Simultaneously, the mid point of mark fine rule c is connected the other end of fine rule b and fixes this moment with the midpoint of fine rule c, and then straight line b passes through 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 fixing fine rule d isometric of the line of the cross on cone flange 4 one end faces with cone flange 4 end face diameters, and the mid point of mark fine rule d; Move cone flange 4; The mid point of fine rule d is contacted with fine rule b, and then accomplish cone flange 4 location, then through welding fixedly cone flange 4; The center of circle of the center of circle and flange circle 1, cone flange 2 and ring flange 3 that has promptly guaranteed cone flange 4 is on same straight line;
The 5th step: see Fig. 6, adopt as above identical method, find out the fine rule e on the ring flange 5; And the mid point of mark fine rule e, during mounting flange 5, rotary flange dish 5; The mid point of fine rule e is contacted with fine rule b, and then accomplish ring flange 5 location, then through welding fixed flange 5; The center of circle of the center of circle and flange circle 1, cone flange 2, ring flange 3 and cone flange 4 that has promptly guaranteed ring flange 5 is on same straight line.
Promptly can accomplish the completion assembly unit of cabin seat easily through as above step, and guarantee the concentricity between each flange, easy to operate, cost is low, is widely used in installing like petroleum pipeline welding, water supply pipe welding and main equipment in the field work.
Fine rule a of the present invention, fine rule b, fine rule c, fine rule d, fine rule e all can adopt cotton thread, perhaps has the single of solid and tension.
