Abstract
The present invention proposes a kind of ship fast accurate trepanning localization method.During shipbuilding, establish three-dimensional modeling, model data is imported in live trepanning computer, coordinate reference points in model can be moved to space any point by computer, data in model will also change with the variation of coordinate points, in practical applications, in order to be compared with the material object of shipbuilding, it is chosen in the segmentation for need trepanning a bit, it usually chooses and is both convenient for measuring, also meet the datum mark as sectional construction simultaneously, using this datum mark as reference point, coordinate points in computer model are selected in and are segmented in base weight chalaza, utilize external laser projection, by the trepanning data fast projection in model to being segmented relevant position, then trepanning is carried out to segmentation using tapping equipment.The present invention can replace the prior art, have precision high, error is small, efficient advantage.Suitable for as ship fast accurate trepanning localization method application.
Description
Technical field
The present invention relates to shipbuilding technical field, more particularly to a kind of ship fast accurate trepanning localization method.
Background technology
Because its process implementing difficulty is big, inefficiency is of poor quality for ship trepanning.Especially ship plank passes through multiple whole plates
Bend, then row is welded, if the trepanning of outside plate is crossed trepanning on plank to be processed by Design spreading in advance, can go out
Existing plank is bent, and the accumulation of error, also needs to take foot for the trepanning of eminence between the multiple working procedures such as plank welding, origin reference location
Hand cradle, inefficiency, the poor large ship of trepanning required precision, the usually direct trepanning in sheet fabrication, and to precision
More demanding high added value ship is usually that trepanning is carried out after closing up.It is complicated since ship-related products size is big, it opens
Kong Duo, so benchmark can not be unified always, positioning difficulty of construction is big, inefficiency.Ship plank surface is curved surface bent plate, is needed
The wooden model of trepanning is made, trepanning scribing line, complex procedures, poor quality are carried out using tapping sample plate.We have invented one thus
The method that kind quickly accurately realizes ship trepanning positioning using Color Laser Projection Technology.Model is utilized to carry out trepanning instead of manual
The process of scribing line can effectively improve the working efficiency and quality of ship trepanning positioning.
Invention content
In order to improve the efficiency and quality of ship trepanning positioning, the present invention proposes a kind of ship fast accurate trepanning positioning
Method.This method realizes that accurate ship trepanning positions by laser projection, solves the efficiency and quality that improve ship trepanning positioning
The technical issues of.
Scheme is used by the present invention solves technical problem：
During shipbuilding, three-dimensional modeling is established, three-dimensional modeling data is imported in live trepanning computer, computer
It is connected with laser tracker and projecting apparatus, by software, the coordinate reference points in model can be moved to space and appointed by computer
Meaning a bit, the data in model will also change with the variation of coordinate points, in practical applications, in order to shipbuilding
Material object compare, chosen in the segmentation for need trepanning a bit, usually choose both be convenient for measure, while also meet as segmentation
Coordinate points in computer model are selected in and are segmented in base weight chalaza using this datum mark as reference point by the datum mark of construction,
It is then set using trepanning by the trepanning data fast projection in model to relevant position is segmented using external laser projection
It is standby that trepanning is carried out to segmentation.
Good effect, since the present invention is moved by the coordinate of model data, so that trepanning is segmented benchmark and model data
Datum mark overlaps, and is projected model data to needing trepanning to be segmented on corresponding position, to rapidly and efficiently form trepanning using laser
Point carries out trepanning with perforate machinery.The prior art can be replaced, has precision high, error is small, efficient advantage.Suitable for making
For ship fast accurate trepanning localization method application.
Specific implementation mode
During shipbuilding, three-dimensional modeling is established, three-dimensional modeling data is imported in live trepanning computer, meter
Calculation machine is connected with laser tracker and projecting apparatus, and by software, the coordinate reference points in model can be moved to sky by computer
Between any point, the data in model will also change with the variation of coordinate points, in practical applications, in order to ship
The material object of construction compares, and is chosen in the segmentation for need trepanning a bit, usually chooses and is both convenient for measuring, while also meeting conduct
Coordinate points in computer model are selected in using this datum mark as reference point and are segmented datum coincidence by the datum mark of sectional construction
On point, using external laser projection, by the trepanning data fast projection in model to relevant position is segmented, then using opening
Hole equipment carries out trepanning to segmentation.
Advantage：
This method can utilize design data, project various axial apertures, in can also installing the technique extension to piping, carry
The true quasi- rate of height work and efficiency.
Embodiment：
With simplest 12 meters high, wide 15 meters of three dimensional unit, one cross wall is leaned on for middle upper part trepanning, is had on hull perpendicular
To reinforcement structure, trepanning is located in structure recess.
The first step, will be in segmented model data transmission to construction computer.
Second step is determined a datum mark convenient for optical measurement stablized in segmentation, is being segmented using laser tracker
It is each on upper measurement 1 points, including tri- directions X, Y, Z of datum mark and coordinate a little to build coordinate system with this data,
And it inputs in computer.
Third walks, and the model data in computer is carried out data reconstruction by coordinate system.
4th step throws trepanning data in segmentation using laser-projector.
5th step overlaps shadow in segmentation by laser-projector and carries out trepanning construction.
