Abstract

The invention relates to a locating datum line drawing and butt joint method in boat segmented manufacturing. The method includes the following steps that firstly, in the time of segmented manufacturing, an outer plate serves as a datum face and four datum lines are drawn on the edge of the outer plate; secondly, after the four datum lines are drawn, the four datum lines are projected to the other side of the outer plate; thirdly, the first step is executed and the fourth step is not started until datum line drawing of all segments is finished; fourthly, as the datum lines are drawn on all the segments, the butt joint seams among the segments are provided with the datum lines, in the time of locating, the datum lines on the two sides of the butt joint seams are parallel and in addition, the distance between the datum lines is 300+n, wherein the n is a welding contraction supplementation value. At the two ends of each butt joint seam, the two butt joint segments are provided with the datum lines which are vertical to the butt joint seam respectively. The datum lines at the two ends are aligned. According to the locating datum line drawing and butt joint method in boat segmented manufacturing, the idea of locating according to the lines in the segmented mode is realized, the segmented locating time is shortened, the segmented position precision is improved, the method is simple and convenient to carry out and the segmented locating quality and efficiency are effectively improved.

Description

In a kind of boat segmental manufacture, position baseline draws and docking calculation

Technical field

The present invention relates to boat segmental manufacture and field of locating technology, particularly relate to drawing and docking calculation of position baseline in a kind of boat segmental manufacture.

Background technology

Development along with shipping industry, being showing improvement or progress day by day of science and technology, the rhythm of Modern Shipbuilding is also more and more faster, how further to reduce work capacity, increase work efficiency, create more benefit, precision shipbuilding is adopted by more and more shipyards, and drawing of segmentation datum line can improve sectional construction, total group, carry precision by actv., greatly shorten total group, lift-launch time.The advanced shipyard of Japan and Korea S is all deeply implemented precision shipbuilding at present, obtained good effect falling aspect this gain, and the most of shipyards of China also do not have the concept of accuracy control at all, inefficiency, the drawbacks such as many of doing over again also significantly come out, and become the obstacle that hinders its development.

Summary of the invention

The object of the invention is to overcome above-mentioned the deficiencies in the prior art, the method that draws of position baseline in a kind of boat segmental manufacture is provided, guarantee segmentation manufacture and positioning datum conformability, the measured error while reducing to use different benchmark.

Technical solution of the present invention is as follows:

1. when manufacturing, segmentation take outside plate as reference plane, suppose that outside plate is that place bow stern left and right, draws a straight line parallel with edge in outside plate longer edges, the outer panel edges 150mm of distance, suppose that at it be outside plate left side, this line is left side datum line, then take this line as benchmark, at outside plate stern end, draws stern end angle square line, apart from outside plate stern end 150mm, with stern end angle square line, at outside plate bow end, draw bow end angle square line again, bow stern end angle square line parallel, and also distance deducts 300mm for outside plate theoretical length L.With left side datum line, on outside plate right side, draw right side datum line, two datum lines are parallel, and distance deducts 300mm for outside plate molded breadth B.

Article four, after datum line completes, then four datum lines are projected to outside plate opposite side.

If segmentation is monoshell, there is an outside plate, at outside plate tow sides and four limits, draw datum line, if segmentation is bivalve, there are two outside plates, at two outside plate tow sides and four limits, draw datum line.

If subsection is upper and lower bow stern, bow stern draws datum line, and size draws datum line according to actual needs up and down.

2., after finish basic section location, start next adjacent sectional location, because segmentation has drawn datum line, so have datum line in segmentation and segmentation butt seam place, during location, guarantee that between the datum line of butt seam both sides, parallel assurance distance is 300+n, n is welding shrinkage compensation.Two datum lines that docking segmentation respectively has a vertical butt joint to stitch in butt seam one end, two foundation directrixes alignment, identical at the butt seam other end.

Compared with prior art, the present invention has guaranteed segmentation manufacture and positioning datum conformability, the measured error while reducing to use different benchmark.

Fig. 2 is split fix datum line spacing schematic diagram.

The specific embodiment

Below in conjunction with drawings and Examples, the present invention is described further, but should not limit the scope of the invention with this.

Drawing and an application process of segmentation manufacture position baseline, comprises

Claims

1. the drawing and a docking calculation of position baseline in boat segmental manufacture, is characterized in that, the method comprises the steps:

Step 1., when sectional making, take outside plate as reference plane, at the edge of the right-hand member of outside plate, draw a straight line parallel with this edge, the spacing at this straight line and this edge is 150mm; Then, take this line as the first datum line (A), at the stern end of outside plate, draw stern end angle square line, stern end angle square line is vertical with the first datum line (A), and the spacing of this stern end angle square line and outside plate stern end is 150mm; Then, take stern end angle square line as the second datum line (B), at outside plate left end, draw bow end angle square line, left end angle square line is parallel with the second datum line, and the spacing of this bow end angle square line and outside plate left end is 150mm; Finally, take left end angle square line as the 3rd datum line (C), at the bow end margin of outside plate, draw a straight line vertical with the 3rd datum line (C), the spacing at this straight line and this edge is 150mm, take this straight line as the 4th datum line (D);

After step 2., four datum lines complete, four datum lines are projected to outside plate opposite side;

Step 3., return to step 1. until 4. all segmentations enter step after completing the work that draws of datum line;

Step 4., because segmentation has drawn datum line, in segmentation and segmentation butt seam place, there is datum line, during location, guarantee between the datum line of butt seam both sides parallel, and distance is 300+n, n is for welding shrinkage compensation, at butt seam two ends, the datum line that two docking segmentations respectively have a vertical butt joint seam, aligns two ends datum line.
