Description
Technical field
The present invention relates to the technical field judging that whether aerogenerator axial fan is qualified, particularly a kind of reversal technique measures the method for aerogenerator axial fan.
Background technology
The blade of aerogenerator axial fan belongs to typical space three-dimensional curved body, for its measurement, namely general employing traditional measurement mode carries out the mode detected with section model, this metering system can only obtain several section molded line limited on motor axial fan, and the transition molded line between section can not be detected, this metering system causes the position degree between blade and blade to be difficult to detect simultaneously, thus can not the vane type line of actual response aerogenerator axial fan and blade relative seat feature, actual requirement of engineering can not be met, in addition, adopt the input checking model material object, increase manufacturing cost.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of and reduce that manufacturing cost, testing result precision that is reliable and visual, that detect is high, the method measuring aerogenerator axial fan with reversal technique of applied range
Object of the present invention is achieved through the following technical solutions: a kind of reversal technique measures the method for aerogenerator axial fan, and it comprises the following steps:
The three-dimensional modeling of S1, aerogenerator axial fan, according to aerogenerator axial fan drawing, utilize three-dimensional software CATIA to carry out three-dimensional modeling, make the size of the endoporus of three-dimensional model and end face all equal with the size of tested aerogenerator axial fan with corresponding;
The conversion of S2, three-dimensional model form, is converted into the file A that three coordinate measuring machine can identify under three-dimensional software CATIA software by three-dimensional model;
The collection of S3, aerogenerator axial fan surface characteristic data point, in three coordinate measuring machine, first open the file A in described S2, three coordinate measuring machine is utilized to gather aerogenerator axial fan surface characteristic data point, the mass data gathered forms cloud data, thus achieve the digitizing of mock-up, then gathered cloud data is output into the file B that reverse software geomagic studio can identify;
The process of S4, aerogenerator axial fan surface characteristic data point, imports to delete disconnected cloud data, the outer acnode of removing body etc. in reverse software geomagic studio, to obtain the digitizing testing model of mock-up by the file B in described S3;
S5, model align, first testing model and theoretical model are imported in reverse inspection software geomagic qualify, endoporus and the end face of described S1 is chosen again on testing model and theoretical model, then the data of endoporus and end face are utilized to be that coordinate system is come together by true origin with leaf position, and ensure that two groups of data are alignd in reverse inspection software geomagic qualify, to analyze picture as detection;
S6, comparative analysis, by the molded line deviate on the axial fan blade of the molded line on the axial fan blade of testing model and theoretical model, then according to the size of deviate to determine that whether aerogenerator axial fan is qualified; Be the deviate that benchmark judges the blade corresponding on theoretical model by a blade of testing model, again according to the size of deviate to determine that whether aerogenerator axial fan qualified, finally export examining reports such as creating annotation, dimension analysis and form and position tolerance assessment
The present invention has the following advantages: (1) present invention eliminates traditional approach and adopts the input checking model material object, reduces manufacturing cost.(2) testing result is reliable and visual, can form establishment annotation, dimension analysis and the form and position tolerance assessment report that both pictures and texts are excellent.(3) improve the precision of detection, the molded line of fan blade and position degree are detected simultaneously, improves the deficiency of traditional measurement mode.(4) measuring method of the present invention extends to the molded line detection of the workpiece of spatial warping, and methods && steps of implementation is consistent, and therefore practicality is very strong, applied range.
