Description

Technical Field

[0001] The utility model relates to the technical field of steel rolling equipment, in particular to an auxiliary detection device for a handheld ultrasonic flaw detector. Background Art

[0002] After the online inspection of steel rolling is completed, the defective samples found need further sampling for precise positioning and anatomical analysis, which is usually done using a handheld ultrasonic flaw detector.

[0003] Publication No. CN218766776U discloses an auxiliary detection device for a handheld ultrasonic flaw detector. This patent utilizes a three-jaw chuck with a centering tip to clamp and rotate a workpiece sample. The device then applies a coupling agent to the sample surface before performing flaw detection. This prevents the adhesion of external contaminants to the sample, which is common when the sample is placed on the ground for testing. This ensures accurate and reliable sample test results, extends the life of the flaw detector probe, and improves detection accuracy. However, this patent still presents the following issues in actual use:

[0004] The workpiece sample is clamped and rotated by the center and three-jaw chuck, and the flaw detection is performed after the coupling agent is applied to the sample surface. This can avoid the current phenomenon that external contaminants easily adhere to the sample when the sample is placed on the ground for testing. However, in actual use, the workpiece cannot be positioned after rotation. When testing different surfaces of the workpiece, the user needs to avoid rotating the workpiece. The workpiece cannot be positioned axially, which is inconvenient for the user and reduces convenience.

After the sliding rod 305 slides, the extrusion spring 307 can be compressed so that the rubber sleeve 306 no longer fits the guide rod 303. Then, the connecting shaft 103 can be moved by the U-shaped rod 309 so that the connecting shaft 103 can rotate. The movable sleeve 102 slides on the movable sleeve 102, so that the distance between the two chucks 105 can be adjusted, and workpieces of different lengths can be positioned. After adjustment, the sliding plate 310 is loosened, and the rubber sleeve 306 is fit with the guide rod 303 under the action of the extrusion spring 307, and the extrusion spring 307 is in a compressed state, so that the rubber sleeve 306 is tightly fit with the guide rod 303, avoiding displacement of the mounting plate 301 and the connecting shaft 103.
