Abstract
The present invention relates to a platform scribing method before a large-scale tubular structural member and a relevant component on manufactured equipment are assembled, which comprises a fixed-point connecting line method, a ground sampling method, a back measuring method and a four-point coplaner method. A long scriber clamped on a strut of a scribing block is pointed to the inner wall of a large-scale tubular member, and a small scriber marks out a plurality of points, and then the points are connected. The fixed-point connecting line method is utilized to solve the problem of scribing on the inner wall of the large-scale tubular member. Limited by the tubular wall structure of the large-scale tubular member, the ground sampling method is utilized to solve the problem that the overall size of the large-scale tube can not be measured by pulling out the large-scale tube. The template back measuring method and the four-point coplaner method are utilized to detect the lineation of the ground sampling method and adjust the lineation. Thereby, the scribing precision is ensured. The present invention satisfies the high precision requirement of the scribing of the large-scale tubular structural member. The various dimensions of scribing reach the optimum, and the construction difficulty of the next procedure is reduced. The scribing method can be popularized in assembly scribing of large-scale tubular structural members manufactured in the petrifaction field, the metallurgy field, the shipping field, the war industry field, etc.

(5) specific embodiment
Embodiment one
This example is typical large-scale tubular construction spare, divides urceolus and inner core, and outer tube structure is seen Fig. 1, and inner tube structure is seen Fig. 7.
Large-scale tubular construction spare platform scoring tool, shown in Figure 1, platform 1 is 16200 * 4500mm, and flatness is less than 0.2mm, tosecan 3 is changed a social system, increase tosecan base weight, increase the pillar height, and at two handles of column bottom dress weldering, its objective is the shake in order as far as possible to avoid ruling, bent plate 2, square chest 4 are purchased by required size, roller positioner 5 is the self-control specific purpose tool, and described line is regularly handed over inspection with instrument, and use qualified back.
Large-scale tubular construction spare platform scribble method comprises following processing step:
1, roller positioner 5 is placed on the platform 1; adjust the spacing of two roller positioners 5; make the deflection deformation minimum of large-scale tubular construction spare; again large-scale tubular construction spare is placed on the roller positioner 5; treat it static after; the quadrant line is reference when closing up with the shell ring butt joint of large-scale barrier part; with upper and lower two arc length is foundation; determine I, III quadrant line; normally mark I, III quadrant line at large-scale barrier part outer wall with tosecan 3, extend 800mm zone inwards by upper port 6 inwalls again and lower port 7 inwalls extend the quadrant line that I, III inwall are marked in the 1600mm zone inwards.
2, because the scriber overhang is oversize when inwall is rule, it is unstable to make it shake, therefore adopts fixed point line method, the dash pin that promptly is clipped on the tosecan pillar points on the large-scale barrier part inwall, mark a plurality of points with little scriber in addition, again these points are linked up, mark inwall I, III quadrant line.After drawing well,, the I that is horizontal, III quadrant line are converted to the upright position with large-scale barrier part half-twist, again with same method, outer wall and inwall II, IV quadrant line are marked in same zone, after large-scale barrier part four-quadrant line has been drawn, I, III are vertical when making it static, II, IV level.
3, because of being subjected to the restriction of large-scale barrier part cylindrical structure, can't on barrel, pull out overall dimension accurately, so adopt ground sample method that quadrant line I two-end-point A, the B of tube bottom thrown into (see figure 2) on the platform 1 with right-angle gauge.Connect AB as center line, cross vertical line Aa and Bb that some A and B make center line AB respectively, get width D respectively at the extended line of Aa and Aa, same, extended line at Bb and Bb is got width D respectively, with width D line between Aa and Bb, when L 〉=12m, D 〉=2m, detect diagonal, nail word line, the length variation that makes every pair of line is guaranteed vertical line Aa and parallel to each other (see figure 3) vertical with center line AB with Bb less than 1mm, detects the distance L between the ab.When line after Aa, Bb meet the demands, it is promptly as the centering line of bent plate 2, with Fig. 4, usefulness shown in Figure 5 is equidistant and line centering bent plate 2.According to the processing capacity size of interior drum flange 8, outer supporting ring 9, on the center line AB on the platform, make each Size Distribution point, throw on the inside and outside wall of large-scale barrier part with tosecan 16 then, mark circumferential thickness processing line (see figure 6).Owing to week upwards mark an astragal, so when bent plate 17 insufficient heights, square chest 4 will be filled up in the bottom.When all overall dimension land used sample methods after large-scale barrier part has been drawn line, utilize back each overall dimension (see figure 7) of survey method correction.
4, enable to cross over structure with the aluminum model and return the survey overall dimension, rule 10 on the two-end-point with the definite value F on the aluminum model 14, line surveys for 11 times to rule in the line and aluminum model 14 on the flange 8 and 10 overlaps, rule 12 on the two-end-point with the definite value G on the aluminum model 15, line surveys for 13 times to rule in the line and aluminum model 15 on the outer supporting rings 9 and 13 overlaps, at this moment by measuring E, can calculate the theoretical length that requires assurance: theoretical length=E+F+G.
5, the line on sustained height on the large-scale tubular construction spare, be at grade in theory, because the error of line, adopt 4 coplanar methods to adjust to the bigger point of deviation, see Fig. 8, superfine line AB two ends are fixed in the height processing line that inwall draws, again other single line CD one end C is fixed in the highly processing line, D holds the end that adjusts, two different surface beelines have so just been formed, adjust end D by conversion, the spacing d of different surface beeline AB and DC is adjusted to zero, just processing is rule and adjusted on the same plane.Described time survey method and 4 accurately adjustment that coplanar method is sample method line over the ground make every size of line more accurate.
