Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flaw detection, in particular to a phased array probe angle adjustment device. Background Art

[0002] Ultrasonic phased array detection technology uses multi-element transducers of different shapes to generate and receive ultrasonic beams. By controlling the different delay times of the pulses emitted (or received) by each element in the transducer array, the phase relationship of the sound waves when reaching (or coming from) a certain point in the object is changed, realizing the changes of the focus and the sound beam direction, so as to realize the beam scanning, deflection and focusing of ultrasonic waves. Then, a method combining mechanical scanning and electronic scanning is used to achieve image imaging.

[0003] Currently, in the existing ultrasonic phased array detection devices, the position of the phased array probe is generally fixed and cannot be adjusted according to actual detection needs. When there are errors caused by mechanical installation or other problems, the sound beam emitted by the phased array probe cannot be focused on the set point, affecting the quality of phased array detection.

[0022] To make the content of the present utility model easier to be clearly understood, the following will further elaborate on the present utility model according to the detailed embodiments and in combination with the drawings.

[0023] Figure 1Schematic structural diagram of the phased array probe angle adjustment device provided by the embodiment of the present application. The device includes a probe frame 1, a hinge seat, a mounting seat 4, a phased array probe 2, and a flipping drive assembly. Among them, the phased array probe 2 is hinged to the probe frame 1 through the mounting seat 4 and the hinge seat, and is driven to flip by the flipping drive assembly, so that the sound beam emitted by the phased array probe 2 is focused on a set point.

[0024] Specifically, the probe frame 1 is used to be placed on a workpiece to be detected, such as a steel pipe, during workpiece detection.

[0025] A hinge seat is arranged on the upper end surface on the right side of the probe frame 1. The mounting seat 4 is hinged in the hinge seat through a first pin shaft 3. Refer to Figure 1 , the axis of the first pin shaft 3 coincides with the diameter of the circle where the arc of the lower cross-section of the probe frame 1 is located, so that when the mounting seat 4 flips around the first pin shaft 3, it flips left and right. The phased array probe 2 is detachably mounted on the mounting seat 4 through bolts, so that the phased array probe 2 flips synchronously with the mounting seat 4.

[0026] The flipping drive assembly is used to drive the mounting seat 4 to flip around the first pin shaft 3. The flipping drive assembly includes a lead screw 8 assembly arranged on the probe frame 1. Refer to Figure 1 , the lead screw 8 assembly includes a nut seat 7 fixedly arranged on the probe frame 1. The nut seat 7 is located on the right side of the mounting seat 4. A lead screw 8 is threaded through the nut seat 7, and the axis of the lead screw 8 is perpendicular to the axis of the first pin shaft 3. One end of the lead screw 8 close to the mounting seat 4 is hinged to the mounting seat 4 through a second pin shaft 5. Among them, the axis of the second pin shaft 5 is parallel to the axis of the first pin shaft 3.

[0027] By rotating the lead screw 8, the lead screw 8 can be moved closer to or away from the mounting seat 4. When the lead screw moves towards the mounting seat 4, the lead screw 8 will exert a thrust on the mounting seat 4, causing the mounting seat 4 to flip counterclockwise; when the lead screw 8 gradually moves away from the mounting seat 4, the lead screw 8 will exert a pulling force on the mounting seat 4, causing the mounting seat 4 to flip clockwise.

[0028] A connecting seat 6 is fixedly arranged on the side of the mounting seat 4 close to the lead screw. Refer to Figure 2 , a waist-shaped hole is formed in the connecting seat 6, and the second pin shaft 5 is arranged in the waist-shaped hole. The long axis of the waist-shaped hole extends along the thickness direction of the mounting seat 4. When the lead screw 8 is rotated, the end of the lead screw generates a horizontal movement, which will cause the second pin shaft 5 to slide in the waist-shaped hole, driving the mounting seat 4 to flip, and thus driving the phased array probe 2 to flip with the first pin shaft 3 as the rotation axis, realizing the adjustment of the sound beam angle.

[0029] Thus, the technical solution of the present application mounts the phased array probe 2 on the mounting seat 4. Through the hinge connection between the mounting seat 4 and the probe frame 1, the phased array probe 2 can rotate around the pin shaft on the probe frame 1. By adjusting the angle of the phased array probe 2, the sound beam emitted by the phased array probe 2 is focused on a set point, reducing the error caused by mechanical installation.

[0030] In addition to the above embodiments, the present utility model may also have other implementation manners; all technical solutions formed by using equivalent replacements or equivalent transformations fall within the protection scope required by the present utility model.
