Description

Ultrasonic flaw detector probe

Technical Field

The utility model relates to an ultrasonic flaw detector probe.

Background

The ultrasonic flaw detector can quickly, conveniently, nondestructively and accurately detect, position, evaluate and diagnose various defects (cracks, looseness, air holes, inclusions and the like) in the workpiece. When the ultrasonic flaw detector is used, the type of the probe needs to be selected according to a detected object, and the current probes include a straight probe, an inclined probe and a variable angle probe. A variable angle probe allows a user to adjust the angle of incidence of the wafer. The adjustable range is from 0 degree to 90 degrees, and longitudinal waves, transverse waves or surface waves with corresponding refraction angles are generated in the detected workpiece along with the change of the incident angle of the wafer.

However, the internal structure of the current variable angle probe is complex, and the alignment of the scale lines is easy to generate errors when the variable angle is adjusted, thereby affecting the measurement result.

SUMMERY OF THE UTILITY MODEL

The utility model provides a simple structure, but accurate angle regulation's ultrasonic flaw detector probe to above-mentioned prior art not enough.

The utility model provides a technical scheme that its technical problem adopted is: a probe of an ultrasonic flaw detector comprises a shell, a damping block, an absorption block and a wafer, wherein the wafer is fixed on the damping block, a cavity is arranged in the shell, the damping block is rotatably arranged in the cavity through a rotating shaft, one end of the rotating shaft extends out of the shell and is provided with a scale, an arc-shaped scale plate is arranged above the shell, and the front end of the scale plate is provided with an indicating needle; a liquid medium is disposed within the cavity.

Furthermore, a groove is correspondingly arranged below each scale on the arc-shaped scale plate, and a bulge corresponding to the groove is arranged on the scale.

Furthermore, the groove and the bulge are both circular.

Furthermore, the bulges are round balls, and elastic cushions are arranged behind the round balls. Preferably, the elastic pad is a silica gel pad.

Preferably, the scales on the arc scale plate are 0-60 degree scale marks in sequence from left to right.

The beneficial effects of the utility model are that: it sets up the damping piece through the pivot, makes the damping piece can rotate along with the pivot to adjust the wafer angle, liquid medium is added to inside cavity, guarantees that the wafer does not influence the testing result after rotating, through the arc scale board of peripheral hardware, makes the scale further method, has improved the precision, moreover, can increase the ball and carry out the accurate positioning of angle, and the ball rear makes the operation of breaking off with the fingers and thumb the scale more smooth and easy after setting up the cushion.

Detailed Description

For a better understanding of the present invention, embodiments of the present invention will be explained in detail below with reference to fig. 1 to 4.

The utility model discloses an ultrasonic flaw detector probe includes shell 1, damping piece 2, absorption piece 3 and wafer 4, and wafer 4 is fixed on damping piece 2, and absorption piece 3 is located the left side of shell 1, and absorption piece 3 can also set to current structure, like the slide wedge structure, no longer gives unnecessary details here. A cavity 5 is arranged in the shell 1, a protective layer 13 is arranged at the bottom of the cavity 5, and the material of the protective layer 13 is the same as that of the protective layer of the existing ultrasonic probe.

Both ends are rotated and are set up on shell 1 around a pivot 6, pivot 6 passes damping piece 2, damping piece 2 is through the rotatable setting of pivot 6 in cavity 5, the one end of pivot 6 is stretched out and is set up a diameter behind shell 1 and be greater than the circular shape of pivot and hold between the fingers portion 14, hold between the fingers and fix a scale 7 that sets up on portion 14, fix in the top front side of shell 1 and set up an arc scale 8, and is concrete, the face parallel and level of shell 1 at arc scale 8 and scale 7 place, even scale 7 can hug closely on arc scale 8. The scales on the arc-shaped scale plate 8 are 0-60 degree scale marks from left to right in sequence. Of course, the scale on the scale plate may be provided with smaller or larger scales depending on the particular size and shape of the housing 1. The front end of the scale 7 is provided with an indicating needle 9, and the indicating needle 9 is aligned with the scale marks. A liquid medium is arranged in the cavity 5, and the liquid medium can adopt a medium such as water or oil.

In order to make angle modulation accurate the utility model discloses every scale below correspondence of arc scale 8 sets up a recess 10, set up a arch 11 that corresponds with recess 10 on the scale 7. In this embodiment, the grooves 10 and the protrusions 11 are preferably circular. Further, as shown in fig. 4, the protrusion 11 is a round ball, and an elastic pad 12 is disposed behind the round ball, so that the elastic pad 12 can be pressed backwards after the round ball is pressed, and retracted into the round ball groove. The elastic pad is preferably a silicone pad.
