[0038] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0039] See Figure 1-12 A fixture for ultrasonic testing of steel plates using a straight probe includes a fixture base 1. A straight probe base 3 for mounting the straight probe is fixed at the top center of the fixture base 1, and a limiting sleeve 4 is fitted around the straight probe base 3. An extension rod connecting frame 2 is hinged to the top of the fixture base 1, and the end of the extension rod connecting frame 2 is used to connect an extension rod. A ball bearing 5 is rolled and limited at the inner bottom of the fixture base 1 by a ball bearing retainer 6. The ball bearing 5 protrudes from the fixture base 1 at a certain height and rolls in contact with the surface of the steel plate to be tested. This fixture can reliably position and mount the straight probe, and can easily connect the extension rod, thus facilitating the assembly of the entire ultrasonic testing fixture to achieve ultrasonic testing of steel plates. It also effectively reduces the friction between the probe and the steel plate during the testing process, resulting in a significant labor-saving effect, reducing the difficulty of the testing operation, and improving testing efficiency. In practical use, the straight probe is positioned and installed on the straight probe base 3, and the straight probe is clamped and fixed by the limiting sleeve 4. Then, the extension rod is installed on the extension rod connecting frame 2, and the entire tooling base 1 is manually pushed to move along the steel plate to be measured. During the movement, the ball bearing 5 rolls and contacts the outer surface of the steel plate, thereby realizing the detection of the steel plate.

[0040] Furthermore, the tooling base 1 includes a disc 102, on the top of which a steel ball bearing support 103 is fixed in a circumferential direction. The interior of the ball bearing support 103 is used for positioning and installing the balls 5, and the bottom end of the ball bearing support 103 is fixedly installed with a ball bearing retaining buckle 6. A hinge seat 101 is symmetrically installed on the top of the disc 102, and the hinge seat 101 is used for hinged extension rod connecting frame 2. A central hole 108 for the straight probe to pass through is machined in the center of the disc 102. A circularly arranged limiting seat 106 is machined in the top of the disc 102, and multiple sets of arc-shaped limiting grooves 107 are machined on the inner side wall of the limiting seat 106. The ball bearing support 103 facilitates the subsequent installation of the balls, and the hinge seat 101 facilitates the subsequent installation of the extension rod connecting frame 2.

[0041] There are eight arc-shaped limiting grooves 107, each with a semi-circular surface. The radius of each semi-circular surface is equal and the distance from the center of the semi-circular surface to the center of the tooling base 1 is equal. Through multiple arc-shaped limiting grooves 107, it is easier to adapt to straight probes of different sizes and models.

[0042] Furthermore, a through hole 104 is machined at the center of the top end of the ball bearing support 103. The through hole 104 facilitates the subsequent injection of lubricating oil into the ball bearing support 103, thereby lubricating the balls 5 and ensuring their smooth rotation.

[0043] Furthermore, the disc 102 is provided with multiple magnet holders 105, which are used to position and install magnets. There are four sets of magnet holders 105, which are arranged in a rectangle with their long sides parallel to the pushing direction of the extension rod. Four circular magnets are attached with glue so that they can be attracted to the steel plate being inspected during testing to prevent the risk of falling off.

[0044] Furthermore, the extension rod connecting frame 2 includes a U-shaped frame 201, and an extension rod connecting sleeve 202 is fixed to the middle part of the outer wall of the U-shaped frame 201. Screw holes 203 are machined on the extension rod connecting sleeve 202. The extension rod connecting frame 2 facilitates subsequent connection of the extension rod. The extension rod connecting sleeve 202 is tapered, thus adapting to extension rods of different diameters.

[0045] Furthermore, the straight probe base 3 includes a mounting cylinder 301 that mates with the central hole 108. The mounting cylinder 301 is welded and fixed to the top of the disc 102. A first vertical groove 303 is machined on the mounting cylinder 301, and a horizontal groove 302 is connected to the bottom end of the first vertical groove 303. The straight probe base 3 described above can be used for subsequent positioning and installation of the straight probe. The first vertical groove 303 and the horizontal groove 302 form a spiral groove, the size of which is slightly larger than the diameter of the straight probe connector, forming a track that allows the straight probe to rotate and adjust its vertical distance.

[0046] Furthermore, the limiting sleeve 4 includes a limiting cylinder 403, with a positioning plate 401 provided on the outer ring of the bottom end of the limiting cylinder 403. An arc-shaped protrusion 402 is machined on the outer edge of the positioning plate 401, and the arc-shaped protrusion 402 cooperates with the arc-shaped limiting groove 107. A retaining groove 404 is machined on the positioning plate 401 and the limiting cylinder 403. The limiting sleeve 4 facilitates subsequent fixing of the straight probe, wherein the width of the retaining groove 404 is equal to the diameter of the straight probe connector.

[0047] Furthermore, the ball retainer 6 has a ball mounting groove 601 machined inside for cooperating with the ball 5. The ball mounting groove 601 enables reliable positioning of the ball 5.

[0048] The specific working process and principle of this utility model are as follows:

[0049] When in use, place the straight probe connecting wire into the hollow cylinder in the straight probe base 3, install it along the first vertical groove 303 and the horizontal groove 302, and rotate it to a suitable position so that the bottom of the straight probe and the steel plate being inspected have the smallest possible gap. Then, align the slot 404 of the limiting sleeve 4 with the protruding position where the straight probe and the probe wire are connected and insert it. Finally, insert the arc-shaped protrusion 402 at the bottom of the limiting sleeve 4 into the arc-shaped limiting groove 107.

[0050] After fixing the straight probe, insert the extension rod of appropriate diameter into the extension rod connector 2. If the connection is not tight or loose, screws can be screwed into the screw holes on the extension rod connector 2 to fix the extension rod.
