Description

Technical Field

[0002] Liquid penetrant nondestructive testing is a surface nondestructive testing method that mainly uses the wetting and capillary effects of liquids to penetrate the open defects on the surface of solid materials. The infiltrated liquid is then precipitated onto the surface through a developer, indicating the presence of defects. The liquid penetrant testing process can be divided into pre-cleaning, penetration, cleaning, drying, imaging, observation and other steps, among which the penetration device is indispensable.

[0003] The existing infiltration device has a relatively simple structure. The material is placed on the material plate to start infiltration, which makes the material infiltration uneven. The place where the bottom of the material contacts the material plate cannot be penetrated by the infiltration liquid, resulting in large errors in the subsequent imaging process.

[0019] The tilting device 10 is arranged on both sides of the stirring device 9; the tilting device 10 includes a limit rod 1001, a top plate 1002, a limit spring 1003, a top block 1004, a support column 1005 and a support block 1006; the top plate 1002 is symmetrically installed at the left and right ends of the stirring blade 902, and a hole is provided in the center to make way for the rotating rod 8; the limit rod 1001 passes through the box body 1 horizontally and is slidably installed on the box body 1; the right end of the limit rod 1001 is installed on the top plate 1002; the limit spring 1003 is installed on the limit rod 1001; a top block 1004 with a wedge surface is installed on the left side of the top plate 1002; the support column 1005 is vertically slidably installed in the groove on the inner wall of the box body 1; the upper end of the support column 1005 is installed with a support block 1006, and the lower end cooperates with the wedge surface of the top block 1004.

[0020] The lifting device 11 is arranged above the stirring device 9: the lifting device 11 includes a material plate 1101, a T-shaped rod 1102, an extrusion plate 1103 and a top column 1104; the material plate 1101 is provided with a mezzanine; the hinge block 6 is installed at both ends of the top of the material plate 1101; the T-shaped rod 1102 is vertically slidably installed on the material plate 1101; the lower end of the T-shaped rod 1102 is installed with an extrusion plate 1103, and when the stirring blade 902 rotates to the highest point, its blade end contacts the extrusion plate 1103; one end of the top column 1104 is symmetrically installed at the left and right ends of the extrusion plate 1103, and the other end is vertically slidably installed in the mezzanine of the material plate 1101.

[0021] Working principle: After the motor 7 is started, the motor 7 rotates with the rotating rod 8. Under the limiting action of the limiting column 903, the rotating rod 8 rotates with the stirring blade 902, and the stirring blade 902 rotates with the rotating block 904. When the rotating block 904 rotates and contacts the fixed block 905, the rotating block 904 is squeezed by the fixed block 905, causing the rotating block 904 to move to the left with the stirring blade 902, and the stirring blade 902 squeezes the sliding spring 901. When the rotating block 904 rotates away from the fixed block 905, the sliding spring 901, the stirring blade 902 and the rotating block 904 reset, the rotating rod 8 drives the stirring blade 902 to rotate, and the rotating block 904 periodically contacts the fixed block 905. The fixed block 905 pushes the stirring blade 902 to slide axially along the rotating rod 8, squeezing the sliding spring 901; the spring resets when it is out of contact, and when the stirring device 9 moves to the left, the stirring blade 902 squeezes the top plate 1002 in the left tilting device 10, causing the top plate 1002 to move to the left, and the top plate 1002 moves to the left with the top block 1004 moving to the left, and the top block 1004 moves to the left. The wedge-shaped surface of the top block 1004 squeezes the support column 1005, causing the support column 1005 to move upward, and the support column 1005 moves upward with the support block 1006 moving upward, and the support block 1006 moves upward to lift one side of the lifting device 11, so that the lifting device 11 tilts, and when the stirring blade 902 is reset, the top plate 1002, the top block 1004, the support column 1005 and the support block 1006 in the left tilting device 10 are reset, and the left side of the lifting device 11 is reset. The top plate 1002 and the top block 1004 in the right tilting device 10 move to the right, and the top block 1004 squeezes the support column 1005, so that the support column 1005 and the support block 1006 move upward, and the right side of the lifting device 11 is lifted. As the stirring blade 902 moves left and right, the lifting device 11 tilts left and right, allowing the material on the material plate 1101 to move left and right, and the holes on the material plate 1101 can contact the bottom of the material more. The bottom of the material can also be penetrated by the permeate, preventing the bottom of the material from being unable to penetrate due to the fit with the material plate 1101; when the end point of the rotating blade of the stirring blade 902 contacts the extrusion plate 1103, the extrusion plate 1103 is forced to move upward, and the upward displacement of the extrusion plate 1103 brings the top column 1104 upward to lift the material. When the stirring blade 902 moves away from the extrusion plate 1103, the extrusion plate 1103 brings the top column 1104 to reset. As the stirring blade 902 rotates, the extrusion plate 1103 brings the top column 1104 up and down, and the material is regularly lifted up and down by the top column 1104, so that the bottom of the material contacts the permeate more fully, and the permeate penetrates more evenly.

[0022] The protection scope of the present invention is not limited to the technical solutions disclosed in the specific implementation methods. Any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical essence of the present invention fall within the protection scope of the present invention.
