Description

Technical Field

[0001] The present invention relates to the technical field of detecting metal materials, and particularly to a non-destructive testing device for detecting metal materials. Background Art

[0002] Metal materials refer to materials with properties such as luster, ductility, easy electrical conductivity, and heat transfer. Before using metal materials, it is necessary to detect them. When ultrasonic waves pass through different materials, changes in acoustic impedance will cause changes in waveform phase and energy. After a series of data acquisitions and calculations, a grayscale value image is formed, which can be used to analyze the internal conditions of the sample, so as to facilitate the detection of metal materials. However, there are still some drawbacks in the existing non-destructive testing devices for detecting metal materials when in use;

[0003] (1) When the existing non-destructive testing device for detecting metal materials is in use, since the surface of the metal material is exposed to the outside for a long time, a layer of dust and impurities is likely to adhere to its surface. When detecting the metal material, the dust and impurities on the surface of the detection metal plate will affect the ultrasonic probe's detection of the detection metal part, which will affect the later detection data and is not convenient to use;

[0004] (2) When the existing non-destructive testing device for detecting metal materials is in use, since the existing testing device does not have a good limiting mechanism for the detection metal part, basically the metal part is directly placed on the detection placement plate for detection. However, sometimes due to human error, the detection position of the detection metal part is placed wrongly, which will affect the later detection of the detection metal part and is not convenient for the use of the testing device;

[0005] Therefore, we propose a non-destructive testing device for detecting metal materials to solve the problems raised above. Summary of the Invention

[0006] The purpose of the present invention is to provide a non-destructive testing device for detecting metal materials to solve the problems in the above background art that when the existing non-destructive testing devices for detecting metal materials on the current market are in use, since the surface of the metal material is exposed to the outside for a long time, a layer of dust and impurities is likely to adhere to its surface. When detecting the metal material, the dust and impurities on the surface of the detection metal plate will affect the ultrasonic probe's detection of the detection metal part, which will affect the later detection data and is not convenient to use, and since the existing testing device does not have a good limiting mechanism for the detection metal part, basically the metal part is directly placed on the detection placement plate for detection.

The right end of the bidirectional lead screw 14 is connected to a turntable 15. Both ends of the bidirectional lead screw 14 are threadedly penetrated and connected with two moving rods 4. Then, by rotating the turntable 15, the two moving rods 4 threadedly connected to the outside of the bidirectional lead screw 14 are moved in position, which can well facilitate the limiting and clamping of inspection metal plates 6 of different lengths.

[0047] Below the bottom of the two limit blocks 5, there are two second connecting rods 18.

[0049] A second rotating motor 26 is installed in a groove on the inner side of the bottom of the mounting rod 11, a rotating shaft 19 is connected below the second rotating motor 26, and the lower part of the rotating shaft 19 penetrates through the mounting rod 11 and extends into the inside of the moving seat 25.

A row of toothed blocks 23 is arranged on both sides inside the moving seat 25, and the row of toothed blocks 23 is arranged and installed at equal intervals. The semi-gear 20 and the toothed block 23 are meshed. Subsequently, the second rotating motor 26 is used to drive the semi-gear 20 at the bottom of the rotating shaft 19 below it to rotate, and then the semi-gear 20 and a row of toothed blocks 23 on both sides inside the moving seat 25 are meshed, so that the moving seat 25 can be well driven to move in a limited position by the semi-gear 20, and it is better to drive the cleaning sponge block 12 below the moving seat 25 to clean and scrape the detected metal plate 6 after clamping and limiting.

[0050] Second limiting rods 21 are installed at both the left and right ends of the moving seat 25, and the two second limiting rods 21 are of the same size.

Finally, the second limiting rods 21 on both sides of the moving seat 25 and the moving grooves 22 on both sides of the bottom of the mounting rod 11 are slidably connected, which can not only well facilitate the limiting of the position of the moving seat 25, but also well facilitate the front and back position movement of the moving seat 25, avoid the influence of dust and impurities on the surface of the detected metal plate 6 on the detection data, and better facilitate the use of the detection equipment.

[0051] The working principle of this embodiment: When using the non-destructive testing equipment for detecting metal materials, first, the detected metal plate 6 is placed above the placing table 3, and then the limiting blocks 5 on the two moving rods 4 are used to limit the position of the detected metal plate 6. Subsequently, the turntable 15 is rotated to drive the two moving rods 4 threadedly connected to the outer side of the bidirectional lead screw 14 to move in position, which can well facilitate the limiting and clamping of the detected metal plates 6 with different lengths. Then, the second connecting rod 18 below the limiting block 5 and the moving rod 4 form an elastic movement through the tension spring 17, which can not only well facilitate the limiting and clamping of the detected metal plate 6, but also well facilitate the clamping of the detected metal plates 6 with different thicknesses. Then, the two electric telescopic rods 7 are used to drive the three ultrasonic probes 8 below their inner sides to move in position, and then the six ultrasonic probes 8 are used to detect the detected metal plate 6 clamped and limited, which better facilitates the use of the detection equipment.

[0052] The first rotating motor 9 drives the first connecting rod 10 below it to rotate. Then, since the first connecting rod 10 is threadedly connected through the mounting rod 11, and then the inner sides of the two first limiting rods 13 are slidably connected to the mounting rod 11 through the sliding grooves 24, it can conveniently limit the position of the mounting rod 11. Subsequently, the second rotating motor 26 drives the half gear 20 at the bottom of the rotating shaft 19 below it to rotate. Then, since the half gear 20 is meshed with a row of tooth blocks 23 on both sides inside the moving seat 25, it can conveniently drive the moving seat 25 to move in a limited position through the half gear 20, and better facilitate driving the cleaning sponge block 12 below the moving seat 25 to clean and scrape the detected metal plate 6 after clamping and limiting. Finally, the second limiting rods 21 on both sides of the moving seat 25 are slidably connected to the moving grooves 22 on both sides of the bottom of the mounting rod 11, which can conveniently limit the position of the moving seat 25 and avoid the dust and impurities on the surface of the detected metal plate 6 from affecting the detection data.
