Description
Technical field
The utility model relates to a kind of ultrasonic probe.
Background technology
When ultrasound examination steel plate or forging, sometimes require both to have carried out compressional wave detection, carry out again shear wave detection; In addition during the ultrasound examination of butt welded seam, want near mother metal butt welded seam and weld seam to carry out ultrasound examination under requirements at the higher level simultaneously, this will detect twice, and one adopts compressional wave normal probe to carry out scanning; Its two employings transverse wave double-bevel detector carries out scanning (see figure 1), causes scanning inefficiency.
Utility model content
The utility model provides a kind of ultrasonic probe that can simultaneously carry out compressional wave, shear wave scanning, solves common compressional wave ultrasonic probe, the common transversal wave ultrasonic ripple probe inefficient technical matters of scanning respectively.
To achieve these goals, the utility model provides following technical scheme:
A shear wave one ultrasonic probe, comprises wedge, and described wedge has a surface level and an inclined-plane, and compressional wave piezoelectric chip is set on the surface level of this wedge, and shear wave piezoelectric chip is set on the inclined-plane of this wedge; Described wedge and P-wave And S piezoelectric chip are all placed in shell; Filling sucting sound material in the shell on wedge top, wedge consists of acoustic window material; P-wave And S damping block is set on P-wave And S piezoelectric chip and connects respectively P-wave And S cable.
Described wedge side has groove.
During the utility model scanning, two kinds of acoustic beams arrive detected material through acoustic window material simultaneously, non-interference, be independent of each other, carry out compressional wave, transversal wave ultrasonic ripple scanning detection simultaneously, to the common parts that need to detect twice, can once complete, automaticity is high, detection efficiency is high, and integrates compressional wave normal probe, transverse wave double-bevel detector simultaneously, has reduced manufacturing cost.

Embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail.
The conventional compressional wave normal probe of the utility model set and conventional transverse wave double-bevel detector are integrated, and become two kinds of ultrasonic probes and pop one's head in into a kind of Integral ultrasonic.As shown in Figure 4.The utility model comprises acoustic absorbant 1, compressional wave piezoelectric chip 2, shear wave piezoelectric chip 8, compressional wave damping block 3, shear wave damping block 6, wedge 5, compressional wave cable 4, shear wave cable 9 and shell 7 etc.Described wedge 5 has a surface level and an inclined-plane (being generally advisable to produce shear wave in the angle of inclination on this inclined-plane between 45～75), and compressional wave piezoelectric chip 2 is set on the surface level of this wedge, and shear wave piezoelectric chip 8 is set on the inclined-plane of this wedge; Described wedge 5 is all placed in shell 7 with P-wave And S piezoelectric chip 2,8; The interior filling sucting sound material 1 of shell 7 on wedge 5 tops, wedge 5 consists of acoustic window material; P-wave And S damping block 3,6 is set on P-wave And S piezoelectric chip 2,8 and connects respectively P-wave And S cable 4,9.
In addition, in order to solve the problem of clutter in acoustic window material, in the two sides of wedge 5, have spaced vertical slots.
Principle of work of the present utility model, compressional wave piezoelectric chip 2 transmitting compressional waves enter into detected workpiece by entrant sound wedge, and sound wave enters workpiece and remains compressional wave, returns to wafer and receives; Do shear wave piezoelectric chip 8 transmitting compressional waves pass through acoustic window material? enter workpiece, according to waveform transformation principle in workpiece according to shear wave transmission, return to wafer and receive.Two groups of wafer each self-reflection and receptions respectively, share acoustic window material, non-interference in workpiece, detect simultaneously, receive simultaneously.
The utility model needs equipment more than two passages to be used in conjunction with, and each passage transmits and receives separately, first compressional wave passage, and it two is shear wave passages; Demonstration can show separately, also can show simultaneously.Can to workpiece, carry out compressional wave and shear wave scanning simultaneously, detect judgement defect.Detection speed is fast, and detection efficiency is high.
When making the utility model, note following some:
1. what liang group wafer did not lean on is too near, in order to avoid impact.
2. this probe need to be applied on two passages and above ultrasonic detecting equipment.
