Description
Technical field
The present invention relates to workpiece repairing technique field, particularly relate to a kind of method based on 3 D-printing repair products.
Background technology
Along with the development of automatic technology, in the field such as commercial production, the automatic assembly line formula mode of production of workpiece is more come
The most universal, especially with the appearance of 3 D-printing (three-dimensional printing) technology, some high-precision products or workpiece also into
The ranks of automated production.
During automated production, due under feeding smooth or control the reasons such as improper, the workpiece causing output is residual
Lack be not all the most common.At present for the product of this class, the most directly destroy and reclaim raw material, consequently, it is possible to product
The work of molding is abandoned completely, but also to increase extra destruction cost, for single workpiece, when production process is entirely
Between, technique and raw-material waste.And, more high-precision product, incomplete product occur that probability is the highest, waste the most serious.
Summary of the invention
The problem existed based on background technology, the invention provides a kind of method based on 3 D-printing repair products, can
The most quickly repair incomplete workpiece.
A kind of based on 3 D-printing repair products the method that the present invention provides, by three-dimensional printing technology to incomplete workpiece
Repair, specifically include following steps:
Obtain certified products data model；
Extract certified products data model surface and cover point, calculate its coordinate, set up reference point coordinate set；
Incomplete workpiece is scanned, and sets up workpiece data model according to scan data；
Extract workpiece data model surface and cover point, calculate its coordinate, set up actual point coordinate set；
Reference point coordinate set and actual point coordinate set are analyzed contrast, extract and only occur in reference point coordinate set
Point sets up coordinate of ground point collection, and extraction only occurs in the point in actual point coordinate set and sets up default point coordinates collection；
According to default point coordinates collection and coordinate of ground point collection, it is thus achieved that repair object set, and according to repairing object set design spray
Rays footpath；
Workpiece is repaired according to jet path jet printing material.
Preferably, repair the region that object set includes being coated with by interconnective reference point and actual point no less than one,
The width of jet path is 1um～100um.
The present invention can be used for the reparation of incomplete workpiece, it is to avoid the waste caused directly destroyed by incomplete workpiece, and, the most right
Incomplete workpiece is repaired, and is to supplement on original process, and compared to the production of new product, low cost, efficiency is high, qualified
Rate is the most secure, is conducive to increasing output ratio and income.
The present invention, by being analyzed with certified products by incompleteness workpiece, obtains and repairs object, automatically calculates injection road
Footpath is repaired, reasonable in design, it is easy to implement, and automaticity is high, and degree of accuracy is high.
Accompanying drawing explanation
Fig. 1 is the flow chart of a kind of based on 3 D-printing repair products the method that the present invention proposes.
Detailed description of the invention
As it is shown in figure 1, a kind of based on 3 D-printing repair products the method that the present invention proposes, it is characterised in that pass through
Incomplete workpiece is repaired by three-dimensional printing technology, specifically includes following steps:
S1, acquisition certified products data model.
Repairing target to incomplete workpiece is that incompleteness workpiece is become certified products, so obtaining certified products data model is
The basis of patch work.
S2, extraction certified products data model surface cover point, calculate its coordinate, set up reference point coordinate set.
S3, incomplete workpiece is scanned, and sets up workpiece data model according to scan data.
S4, extraction workpiece data model surface cover point, calculate its coordinate, set up actual point coordinate set.
S5, reference point coordinate set and actual point coordinate set are analyzed contrast, extract and only occur in reference point coordinate set
In point set up coordinate of ground point collection, and extract and only occur in the point in actual point coordinate set and set up default point coordinates collection.
Step S2 and step S4 only consider that certified products data model covers point with workpiece data model surface, does not consider it
Internal point, i.e. decreases amount of calculation, does not the most affect the profile contrast of workpiece and certified products.
In step S5, the target face that coordinate of ground point concentrates each point to constitute is the state that workpiece incompleteness position should present,
Default point coordinates concentrates actual the currently practical state in corresponding workpiece incompleteness position that each point is constituted.Target face is with actual face one by one
Corresponding composition is no less than a hollow closing structure, the actual filling being equal to hollow closing structure of repairing of incomplete workpiece.
Specifically, the quantity of hollow closing structure, why more than or equal to one, is because surface of the work and is likely to be of many
Individual mutual disjunct incomplete position.
S6, according to default point coordinates collection and coordinate of ground point collection, it is thus achieved that repair object set, and according to repair object set design
Jet path.
Object of repairing in this step is actually the hollow closing structure sum analyzed in last step, i.e. repairs
Object includes the region being coated with no less than by interconnective reference point and actual point.
Due to, workpiece patch work is more careful relative to the production of new product, so, the width of jet path was difficult to
Greatly, concrete value can be between 1um～100um, such as 5um, 10um, 15um etc..
S7, according to jet path jet printing material repair workpiece.
Jet path designs according to repairing object i.e. hollow-core construction, can accurately beat the position of workpiece disappearance
Print is repaired, and incompleteness workpiece is become certified products.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope that the invention discloses, according to technical scheme and
Inventive concept equivalent or change in addition, all should contain within protection scope of the present invention.
