Abstract
The utility model provides a portable full-digitized ultrasonic flaw detecting imaging instrument. The utility model has the advantages that the utility model adopts the type A pulse reflecting principle, and real-time display with images can be realized, the shapes and depths of the internal defects of the metallic materials can be detected, which make the safety evaluation of the products convenient to realize; the required parts of the existing such as flaw detecting instrument such as a time base board, a video display, and the voltage regulating board of a high-frequency power supply, a multifunctional control board is especially provided, and thus the size and weight of the utility model is greatly reduced, and the utility model is convenient to carry.
Description
The utility model relates to the nondestructive examination instrument, particularly relates to the instrument with Ultrasonic Nondestructive weld seam inherent vice.
As everyone knows, method and the instrument that carries out nondestructive examination has multiple.For example, A type pulse reflection ultra-sonic defect detector is widely used in the detection of industrial products, but this instrument is to represent with pulse signal to detected defective, can not reflect the concrete shape of defective; Though ray detection can provide the projection of defective in transmission direction, can not determine the degree of depth of defective.Therefore, existing inspection technique and defectoscope just manifest some significantly deficiencies in giving the safety evaluation of product, bring certain difficulty to safety evaluation work, and present in addition existing detector device volume is bigger, so be not easy to carry and use in the open air, be unsuitable in work high above the ground especially.
The purpose of this utility model be propose a kind of be convenient to carry can at the construction field (site) or detect the instrument that on on-the-spot plane, facade and the various workplace detected defective is carried out real time imaging.
The utility model can be realized by following measure: a kind of portable totally digitilized UT (Ultrasonic Testing) imaging instrument, by probe, coordinate scanning frame, flaw detection unit, sampling unit, information process unit, display unit, and printing device etc. form.Wherein said probe, sampling unit, information process unit, display unit and printing device are conventional components, can buy on market.Said coordinate scanning frame is common coordinate scanning frame, and different is the strong magnetic-disc that four band universal heads are housed on four angles of its base, and the scanning frame is stably fixed on plane, facade and the curved surface, has enlarged range of application.In said flaw detection unit, the time substrate, the video that have removed general ultra-sonic defect detector indispensability show and amplify plate and high frequency electric source voltage stabilizing plate, a multi-functional trigger board is installed in addition, circuit such as this multi-functional trigger board integrates synchronous triggering, frequency division, the ripple amplitude limit that goes to begin, emission spike pulse, in addition, the two cover power supplys that the utility model will be detected a flaw and imaging divides the two cover power supplys, two of body structure to overlap CRT monitor make a cover power supply into and offer flaw detection and imaging system simultaneously.
Flaw detection imaging instrument of the present utility model can detect the shape and the degree of depth of metal material inherent vice, and the safety evaluation of product is brought great convenience.In addition, the volume of flaw detection imaging instrument of the present utility model is little in light weight, easy to carry, applied widely, is particularly suited for manipulating at the scene.
Below in conjunction with accompanying drawing the utility model is described in further detail, but the utility model is not limited to the content of accompanying drawing.
Figure one is the one-piece construction figure of the utility model imaging instrument.Figure two is the circuit diagram of multi-functional trigger board in the utility model flaw detection unit, and figure three is the structural drawing of universal device on the scanning frame base of the present utility model.
In figure one, flaw indication enters flaw detection unit [2] by probe [7], sampling unit [3] will be delivered in the information process unit [4] from the coordinate setting signal of coordinate scanning frame [1] with from the signal of flaw detection unit [2], show by display unit [5] more after treatment, can print by printing device [6] simultaneously.Information process unit [4] is selected the 486SX/33 notebook computer for use.
In the multi-functional trigger board circuit shown in the figure two, the resonant circuit (1) that vibration frequency is approximately 2000Hz can produce synchronizing pulse; Frequency dividing circuit (2) is used to provide the repetition frequency synchronizing signal; Trigger circuit (3) are the high-frequency impulse trigger, and the time is about 0.3 μ S; (4) be begin wave circuit and the amplitude limiter circuit that limits echo signal amplitude of going that the beginning ripple restriction of high-frequency emission pulse is entered the A/D plate.
In figure three, { { 2} is installed in the base plate of coordinate scanning frame base, and { on the 1}, { 4} is contained in universal socket and { among the 3}, can rotates arbitrarily universal joint 3} universal socket by screw.{ strong magnetic sheet { 5} is equipped with in the bottom of 4} at universal joint.
Claims (2)
1, a kind of portable totally digitilized UT (Ultrasonic Testing) imaging instrument, forms by probe, coordinate scanning frame, flaw detection unit, sampling unit, information process unit, display unit and printing device, it is characterized in that in said flaw detection unit, having one to integrate synchronous trigger circuit, frequency dividing circuit, go the multi-functional trigger board that begins the ripple amplitude limiter circuit, launch the trigger pip circuit.
2, a kind of according to the described portable totally digitilized UT (Ultrasonic Testing) imaging instrument of claim 1, it is characterized in that on four angles of the base of said coordinate scanning frame, four strong magnetic sheets that have universal head being housed.
