Technical Field
[0001] This utility model relates to the field of magnetic particle inspection and flaw detection machine technology, and in particular to a magnetic particle inspection and flaw detection machine. Background Technology
[0002] Magnetic particle inspection flaw detectors are non-destructive testing equipment that uses magnetic particles to display defects. They are mainly used to detect cracks, folds, and inclusions on the surface and near the surface of ferromagnetic materials. Their working principle involves applying a magnetic field to the workpiece to magnetize it. If a defect exists, a leakage magnetic field is generated at the defect location, attracting the applied magnetic particles and forming observable magnetic traces. This allows for the location and assessment of the defect. These devices can be categorized into fixed, mobile, and portable types based on their application scenarios. They are widely used in machinery manufacturing, aerospace, petrochemical, and automotive industries, effectively ensuring the quality and safety of ferromagnetic workpieces and are an indispensable piece of equipment in industrial non-destructive testing.

[0021] This utility model has the following beneficial effects: 1. In this utility model, when the driving component is activated, the threaded sleeve is rotated inward. At this time, the threaded sleeve will drive the square connecting rod and the O-ring to move inward. Simultaneously, the flaw detector will squeeze the arc-shaped rubber plate. The arc-shaped rubber plate will rotate according to the angle of the flaw detector's surface, causing the fixing rod to rotate inside the cylindrical sleeve. At the same time, the threaded column will rotate. The threaded column will adjust the distance along the threaded hole on the O-ring, causing the spring to be compressed. This achieves the function of buffering the flaw detector during clamping and preventing damage to the clamp and flaw detector caused by squeezing. 2. In this utility model, after clamping, the cylinder is activated. At this time, the cylinder will drive the push rod to push downward. The push rod will push the sliding plate, so that the sliding plate will move along the sliding groove on the square support column and the surface of the limiting rod one. At the same time, the spring two is squeezed and deformed. When adjusted to a suitable position, the flaw detection plate can be used for flaw detection. This realizes that the height of the flaw detection plate can be freely adjusted according to the actual situation, which is convenient for better flaw detection. Attached Figure Description

The beveled latching block 4033 allows it to precisely cooperate with other components in a specific position, thereby realizing the latching function and ensuring that the entire component is both flexible and reliable during operation.
[0029] Working principle: First, the drive unit 2081 is activated. This drives the coupling 2082 and the double-threaded rod 2083 to rotate. Simultaneously, the double-threaded rod 2083 pushes the threaded sleeve 202 outward. At this point, the flaw detector is inserted. The flaw detector will press against the inclined plate block 4033, which in turn presses against the spring 402. When the flaw detector reaches the bottom of the inclined plate block 4033, the spring 402 springs up, locking the flaw detector. Then, the drive unit 2081 is activated, rotating the threaded sleeve 202 inward. 2 will drive the square connecting rod 203 and the O-ring 204 to move inward. At the same time, the flaw detector will squeeze the arc-shaped rubber plate 2072. At this time, the arc-shaped rubber plate 2072 will rotate with the angle of the surface of the flaw detector, driving the fixing rod 2071 to rotate inside the cylindrical sleeve 2064. At the same time, the threaded column 2061 will rotate. At this time, the threaded column 2061 will adjust the distance along the threaded hole 205 on the O-ring 204, so that the spring 2063 is compressed. This achieves the function of buffering the flaw detector during the clamping process and preventing the fixture and the flaw detector from being damaged due to compression. After clamping, cylinder 303 is activated, which drives push rod 304 downward. Push rod 304 then pushes sliding plate 305, causing sliding plate 305 to move along the surface of sliding groove 302 on square support column 301 and limit rod 3061. At the same time, it compresses spring 3062, causing it to deform. When adjusted to a suitable position, flaw detection plate 5 can be used for flaw detection. This allows the height of flaw detection plate 5 to be freely adjusted according to actual conditions, facilitating better flaw detection.
