Description

Technical Field

[0001] This invention belongs to the field of ultrasonic flaw detection technology, specifically relating to a multi-winding box-type ultrasonic flaw detection device. Background Technology

[0002] When a workpiece is deformed by external force, it may develop defects such as wrinkles and scratches on its surface. Ultrasonic flaw detection can inspect the surface and internal quality of the component without damaging the workpiece or raw material. When ultrasonic waves encounter defects such as cracks, they will generate diffraction waves superimposed on the normal reflected waves at the tip of the defect. The probe detects the diffraction waves, thereby determining the size and depth of the defect.

[0003] When using existing ultrasonic flaw detection equipment to inspect the interior of workpieces such as boxes, the operator holds the ultrasonic flaw detection instrument and inserts it into the box for inspection. When the operator moves the ultrasonic flaw detection instrument, the instrument is prone to shifting, which affects the determination of the flaw detection results. Utility Model Content

[0020] In a preferred embodiment, please refer to Figures 1 to 2A drive mechanism 400 is provided between multiple guide wheels 300. The drive mechanism 400 consists of a knob 401, a first rotating rod 402, a first threaded rod 403, a first bevel gear 404, a second bevel gear 405, a second threaded rod 406, a threaded sleeve 407, and a second rotating rod 408. The knob 401 is rotatably connected to the side of the ultrasonic flaw detector body 100. The first rotating rod 402 is fixedly provided on the side of the knob 401.

The cross-sectional shape of the first mounting groove and the second mounting groove is rectangular.

[0022] In this embodiment, rotating the knob 401 can drive the first rotating rod 402 and the first threaded rod 403 to rotate. The rotation of the first threaded rod 403 drives multiple first bevel gears 404 to rotate simultaneously. The rotation of the first bevel gears 404 drives the second bevel gear 405, the second rotating rod 408, and the second threaded rod 406 to rotate. The rotation of the second threaded rod 406 drives the threaded sleeve 407 to move outward or inward simultaneously. The movement of the threaded sleeve 407 drives multiple sets of symmetrical first U-shaped plates 301 and guide wheels 300 to move closer or further apart simultaneously. Thus, the spacing of the guide wheels 300 can be adjusted according to the spacing of the inner wall of the box, making the guide wheels 300 suitable for boxes of various sizes, with strong applicability.

[0023] In a preferred embodiment, please refer to Figures 1 to 4An angle adjustment assembly 600 is provided above the main body 100 of the ultrasonic flaw detector. The angle adjustment assembly 600 consists of a second U-shaped plate 601, a rotating shaft 602, a mounting plate 603, a first threaded hole 604, a bolt 605, and a rotating plate 606. The second U-shaped plate 601 is fixedly provided on the top surface of the output end of the cylinder 500. The rotating shaft 602 is provided through the inner side of the second U-shaped plate 601, and the mounting plate 603 is provided through the outer side of the rotating shaft 602. Three first threaded holes 604 are arranged in a circumferential array on the side of the second U-shaped plate 601. The rotating plate 606 is fixedly provided on the side of the rotating shaft 602 near the first threaded hole 604, and the bolt 605 is provided through the side of the rotating plate 606.

[0024] In this embodiment, the rotating shaft 602 is rotatably connected to the second U-shaped plate 601, and the rotating shaft 602 is fixedly connected to the mounting plate 603. The mounting plate 603 is fixedly connected to the ultrasonic probe 101. The left and right sides of the mounting plate 603 are rotatably connected to the inner wall of the second U-shaped plate 601, respectively. The first threaded hole 604 is adapted to the bolt 605. The rotating plate 606 has a second threaded hole adapted to the bolt 605 through its side. The bolt 605 passes through the second threaded hole through the rotating plate 606. Rotating the rotating plate 606 can align the second threaded hole with the first threaded hole 604 and connect it to the first threaded hole 604. The bolt 605 is threadedly connected to the second U-shaped plate 601 and the rotating plate 606 through the first threaded hole 604 and the second threaded hole, respectively. Rotating the rotating plate 606 can drive the rotating shaft 602 and the mounting plate 603 to rotate, thereby driving the ultrasonic probe 101 to rotate. To avoid the wires connecting the ultrasonic probe 101 from getting tangled, the rotation angle of the rotating plate 606 is no more than 180 degrees.

[0025] In this embodiment, the control cylinder 500 drives the second U-shaped plate 601 to move up or down, which can adjust the height of the ultrasonic probe 101 as needed. Rotating the rotating plate 606 can drive the ultrasonic probe 101 to rotate 90 degrees or 180 degrees. The second threaded holes are all connected to the first threaded hole 604, which facilitates the ultrasonic probe 101 to detect the top surface or the front and rear sides of the box. When the second threaded hole is connected to the first threaded hole 604, rotating the bolt 605 drives the bolt 605 to be threadedly connected to the second U-shaped plate 601 and the rotating plate 606 at the same time, which can maintain the detection direction of the ultrasonic probe 101 after rotation.

[0026] The working principle of this utility model is as follows: When using the device, the ultrasonic flaw detector body 100 is placed on the bottom surface of the box to be inspected. Rotating the knob 401 drives the first rotating rod 402 and the first threaded rod 403 to rotate. The rotation of the first threaded rod 403 drives multiple first bevel gears 404 to rotate simultaneously. The rotation of the first bevel gears 404 drives the second bevel gear 405, the second rotating rod 408, and the second threaded rod 406 to rotate. The rotation of the second threaded rod 406 drives the threaded sleeve 407 to move outwards or inwards simultaneously. The movement of the threaded sleeve 407 drives multiple sets of... The first U-shaped plate 301 and the guide wheel 300 move closer or further apart simultaneously, thereby adjusting the spacing of the guide wheel 300 according to the spacing of the inner wall of the box, until the guide wheel 300 are simultaneously pressed against the inner wall of the box. When the operator pushes the handle 203 in conjunction with the roller 201, the ultrasonic flaw detector body 100 can be moved inside the box. The guide wheel 300 rotates as the ultrasonic flaw detector body 100 moves, thereby playing a guiding role when moving the ultrasonic flaw detector body 100 and preventing the ultrasonic flaw detector body 100 from deviating.

[0027] The control cylinder 500 moves the second U-shaped plate 601 up or down to adjust the height of the ultrasonic probe 101 as needed. When the detection direction of the ultrasonic probe 101 needs to be adjusted, the bolt 605 is rotated to disengage from the first threaded hole 604 of the second U-shaped plate 601. Rotating the rotating plate 606 can rotate the ultrasonic probe 101 90 degrees or 180 degrees. When the second threaded hole is reconnected to the first threaded hole 604, rotating the bolt 605 causes the bolt 605 to be threadedly connected to both the second U-shaped plate 601 and the rotating plate 606. This can maintain the detection direction of the ultrasonic probe 101 after rotation, making it convenient for the ultrasonic probe 101 to detect the top surface or the front and rear sides of the box.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
