The automatic ultrasonic detection device is characterized by comprising a travelling mechanism, wherein a six-axis manipulator, a probe frame and an ultrasonic probe, which are controlled by a motion control system, are connected to the travelling mechanism in sequence. According to the invention, the problems of interference caused by outline shape, signal interference, size changing and coupling and the like in automatic ultrasonic detection of the castings are solved; and the automatic ultrasonic detection device disclosed by the invention is capable of increasing the ultrasonic detection efficiency of the castings, reducing the labour intensity of detectors and increasing the stability and the reliability of detection results.
Description
Technical field
The present invention relates to a kind of automatic detection device, especially relate to a kind of ultrasound wave automatic detection device that is applicable to Complicated structure casting.
Background technology
Casting is the main method that obtains large and complex structure parts, as steam turbine, gas turbine cylinder, valve body etc., frame, the termination etc. of mining machinery.For defects such as the slag inclusion forming in casting process, shrinkage porosite, loose, pores, conventional ultrasound examination controls to detect these defects, to ensure product quality.At present, in ultrasound examination, owing to being subject to the restriction of foundry goods space structure, conventional ultrasonic automatic detection system is suitable at most 5 axle linked systems, cannot be applicable to the detection of labyrinth workpiece, so, casting ultrasonic detects and mainly relies on the mode of scanning manually to realize detection, this mode detection efficiency is low, personnel labor intensity is large, and testing result judges according to personal experience, larger to the reliability effect of testing result, simultaneously, the ultrasonic equipment of manual checking cannot recording process waveform, causes reviewing.
Also do not overcome at present the device of above-mentioned defect.
Summary of the invention
The object of the invention is to overcome the defect of prior art, providing a kind of solves in the automatic detection of casting ultrasonic, be subject to the problems such as interference, signal interference, change in size and coupling that contour structures affects, can improve casting ultrasonic detection efficiency, reduce testing staff's labour intensity, improve the stability of testing result and a kind of ultrasound wave automatic detection device that is applicable to Complicated structure casting of reliability.
The present invention realizes in the following way:
A ultrasound wave automatic detection device that is applicable to Complicated structure casting, is characterized in that: it comprises a travel mechanism, is associated with successively 6 axis robot, probe holder and ultrasonic probe by kinetic control system control in travel mechanism;
Described travel mechanism is assembled to travel mechanism, Z-direction travel mechanism and Y-direction travel mechanism by X, and described 6 axis robot are connected to Z-direction travel mechanism bottom;
On described probe holder, pneumatic cylinder is installed;
Described ultrasonic probe adopts the preposition method of A/D modular converter, and buffering and compensating unit are set in described probe holder, and probe holder automatic coating couplant.
The present invention has following effect:
1) the ultrasound wave automatic detection device that is applicable to Complicated structure casting provided by the invention, it comprises a travel mechanism, in travel mechanism, be associated with successively 6 axis robot, probe holder and ultrasonic probe by kinetic control system control, ultrasonic system adopts the preposition method of A/D modular converter, efficiently solves decay and the interference problem of simulating signal in long Distance Transmission process;
2) buffering and compensating unit are set in probe holder, avoid mechanical arm to walk according to theoretical value line, the problem that probe pressure is non-constant and mechanical arm clashes into foundry goods when physical size changes.
3) ultrasonic method adopts contact method, probe holder automatic coating couplant, and the shear wave of realizing foundry goods detects.
4) this method compared with prior art, solve in the automatic detection of casting ultrasonic, be subject to the problems such as interference, signal interference, change in size and coupling that contour structures affects, one of effective ways of instead of manual detection, can improve casting ultrasonic detection efficiency, reduce testing staff's labour intensity, improve stability and the reliability of testing result, and testing process can be reviewed.
