Description
Technical field
The invention belongs to the detection technique field, the definite aero-engine labyrinth disc hot list processing thickness information extracting system of saying so.
Background technology
The spraying of aeromotor labyrinth is a kind of common hotlist process technology, and each large aerospace engine processing enterprise all is equipped with special painting workshop.Because spraying coating process, there is certain uncertainty in coating thickness, must detect coating thickness.
Existing labyrinth coating thickness measurement method mainly contains: the wedge cutting method, light cuts method, electrolytic process, thickness difference mensuration, weight method, x-ray fluorescence method, β ray backscattering method, capacitance method, ultrasonic method and eddy current measurement method etc.The first five kind is to diminish detection in these methods, and measurement means is loaded down with trivial details, and speed is slow, is applicable to pick test more.X ray and β rays method are contactless nondestructive measurements, but the device complex and expensive, measurement range is less.Capacitance method, ultrasonic method and eddy current measurement method have strict requirement to coated substrate material and coating material, need use corresponding probe at different substrates and coating.In addition, existing characterization processes all is to detect or the method for local detection, can't finish fast detecting and assessment to whole labyrinth coating surface fast, occurs the zone of omission easily and causes product to have hidden danger of quality.
The present invention proposes a kind of aero-engine labyrinth disc hot list processing thickness information extracting method of novel holographic robotization, realized labyrinth surface coating thickness complete, efficiently, the measurement of robotization, solved the problem that existing method exists effectively.
Summary of the invention
The purpose of this invention is to provide a novel aeromotor labyrinth coating thickness information extraction mode, realized aeromotor labyrinth surface coating thickness complete, efficiently, the measurement of robotization.
Principle of the present invention is, cooperate industrial robot, utilize the non-contact laser measuring technique with the high precision in control positioner, before spraying and afterwards, the spraying area of aeromotor labyrinth is carried out three-dimensional surface measurement respectively, operation with the data of twice measurement are subtracted each other along the spraying direction can draw spraying area complete coating thickness distributed intelligence comprehensively.
Technical solution of the present invention is: system is made up of industrial robot 1, non-contact laser scanner head 2, high precision in control positioner 3 and aeromotor labyrinth 4 to be sprayed, as shown in Figure 1.Wherein non-contact laser scanner head 2 is connected with industrial robot 1 by data cable, the transmission scan-data, industrial robot 2 links to each other with switch board by communication cable, accept movement instruction transmission scan data simultaneously, switch board links to each other with main control computer by network interface, transmit steering order and scan-data, main control computer is mainly finished core missions such as motion planning parameters of scanning paths, data presentation, data processing, coating thickness calculating.High precision in control positioner 3, industrial robot 1 link to each other with main control computer by data line, accept the steering order that main control computer sends, and finish spraying operation.Aeromotor labyrinth 4 to be sprayed is fixed on the positioner.
The groundwork flow process of system is as follows: the user imports the basic parameters such as range of size of part to be sprayed by main control computer, and system at first carries out planning parameters of scanning paths, and control robot, positioner and laser feeler carry out surface scan.Scan-data carries out real-time three-dimensional and shows, until the measuring task of finishing whole work-piece.Next spray robot is finished spraying operation according to the technological requirement of spraying.Scan robot then and once more spraying area is carried out surface scan.Final system along spraying the operation that direction is subtracted each other, draws spraying area coating thickness data to twice scan-data, and requires to compare with spraying, provides survey report.
Because native system adopts six degree of freedom industrial robot and non-contact laser scanner head, detection efficiency is higher than the conventional coatings detecting thickness device based on a detection far away.Can finish surface three dimension scanning fast, and serve as according to the control program that generates spraying process fast, greatly improve the work efficiency that aeromotor labyrinth thickness information is extracted with the three-dimensional data of piece surface.In addition, native system can be realized the automatic planning in coat thickness detection path, has overcome problems such as manually getting efficient that point detecting method exists and technical requirement.This cover detection system volume is little, can be placed on the spraying scene, is connected with paint finishing, accomplishes the survey of limit spraying frontier inspection, forms closed-loop system, improves the precision of coating.
The beneficial effect that the present invention reached is: the present invention creatively combines laser surface scanning and industrial robot spraying, has solved the problem of aeromotor labyrinth coating thickness information extraction robotization.The present invention can obtain comprehensive aeromotor labyrinth coating thickness distributed data, has eliminated existing mode and has relied on the various hidden danger that artificial partial check exists.The present invention provides the brand-new technology means for the quality control of aeromotor labyrinth spraying coating process.To greatly improve the efficient of aeromotor labyrinth coat thickness detection by this project implementation, promote labyrinth spraying coating process precision, reduce staff's labour intensity, bring considerable economic and social benefit.In addition, simultaneously, this project assorted software systems can file, add up, analyze testing result, thereby set up a cover complete coating quality monitoring, analytic system, help enterprise to pinpoint the problems and find the root place of problem.At present domestic also do not have similar equipment to occur, and the research of this project has originality, will fill up the blank in domestic air mail engine labyrinth fluted disc coating thickness information extraction field.
