Abstract
The utility model relates to a combined probe capable of respectively trimming acoustic beam angles, which comprises a probe shell and a probe cover, wherein a plurality of wire-focusing ultrasonic probes are arranged in the probe shell. A supporting shaft supported by the lateral walls at both ends of the probe shell is transversely penetrated and connected to the position below the wire-focusing ultrasonic probes. The lateral walls of the bilateral probe shell of the wire-focusing ultrasonic probes and the lateral walls of the probe cover are respectively connected with adjusting screws oppositely. Space is arranged between the bilateral walls of the wire-focusing ultrasonic probes and the inner wall of the probe shell, and between the inner walls of the probe cover. Space is arranged between the bottom of the wire-focusing ultrasonic probes and the bottom surface inside the probe shell. Locking nuts are connected with the adjusting screws in order to lock the adjusting screws. The utility model has the advantages of simple structure and easy use. The utility model can perform the trimming of acoustic beam angles to each ultrasonic probe independently and solely by the adjusting screws. Therefore, the pointing consistency of the focused acoustic beams of the ultrasonic probe can be adjusted to meet the requirement. The utility model can perform positioning reliably, and can meet flaw detection of pipe materials of different specifications.
Description
Technical field
The utility model relates to metal material nondestructive testing technique field, is applied in the ultrasonic automatic flaw detecting device of tubing (steel pipe, copper pipe, titanium pipe etc.), is applicable to the conveying of tubing spiral progression, the Non-Destructive Testing of the tubing of diameter 〉=Φ 48mm.
Background technology
In order to guarantee the product quality of metal pipe material, carry out Non-Destructive Testing to tubing, with in the method for ultrasonic inspection, the diameter of tubing 〉=Φ 76mm generally adopts the tubing spiral relatively-stationary form of advancing, pop one's head in.In the process of ultrasonic inspection, need to use couplant between probe and the measured object, in tubing automatic flaw detection generally all water make couplant.According to the ultrasonic inspection principle, the axis of probe is wanted the certain distance of parallel offset diameter of steel tube direction, i.e. eccentric throw; The outside surface of probe and pipe will keep the distance of about 20mm simultaneously.
In order to improve flaw detection efficient, the general rotating speed that increases pipe that adopts perhaps adds coarse pitch.Because tubing allows certain bending and ovality in the process of making, so the rotating speed of pipe can not be too high, generally is no more than 800 rev/mins.Under same rotating speed, add coarse pitch, can improve inspection speed.Pitch strengthens, and just must adopt the hyperchannel coupling probe, could satisfy the flaw detection requirement.According to flaw detection relevant technologies requirement, the acoustic beam directive property of every probe in the hyperchannel probe must be consistent, and it is 10 micron-sized requiring being focused into mutual error on the exit point.Coupling probe in the past has two kinds of versions, a kind of be several independent probe assembled package in a shell, another kind is to make several probes to be encapsulated in the shell on a wafer.In a single day these two kinds of textural association probes process, each probe is just fixed in shell, and the angle of focused beam is just non-adjustable.Because probe has tolerance at aspects such as processing, the error that several probes are mutual makes the acoustic beam sensing of several probes be difficult to reach requirement; And a bad or damage of probe performance is wherein arranged, and whole coupling probe must be scrapped.Therefore the difficulty of processing of coupling probe is very big, even in certain tubing specification limit, reach requirement, changed specification after index request do not reached again.Increased flaw detection operating personnel's debugging difficulty so again.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to use, can pop one's head in to the combined ultrasonic of each single probe fine setting acoustic beam angle respectively.
For achieving the above object, the utility model is taked following design proposal:
A kind of coupling probe that can finely tune the acoustic beam angle respectively, it includes the probe shell, probe cover, in the probe shell, a plurality of line focus ultrasonic probes are housed, the bottom of this line focus ultrasonic probe is connected with cable, it is characterized in that: the lower, transverse cross-under at described line focus ultrasonic probe has a back shaft by probe shell two ends side wall support, on the sidewall of the probe shell of online focus supersonic probe both sides and on the sidewall on the probe cover to being connected with set screw respectively, online focus supersonic probe two side and probe shell madial wall, be provided with spacing between the probe cover madial wall, be provided with spacing between the bottom surface in the bottom of online focus supersonic probe and the probe shell.
In order to lock set screw, on described set screw, be connected with set nut.
The utility model has the advantages that: simple in structure, easy to use, can finely tune the acoustic beam angle separately to each ultrasonic probe respectively by set screw, the sensing consistance of the focused beam of ultrasonic probe is adjusted to met the demands, can reliably locate, and satisfy the flaw detection of different size tubing.
