Description

Technical Field

[0001] The utility model relates to the technical field of magnetic powder flaw detection equipment, in particular to a magnetic powder spraying mechanism for magnetic powder flaw detection. Background Art

[0002] Magnetic particle inspection utilizes the interaction between the leakage magnetic field at the defects of the workpiece and the magnetic powder. It utilizes the difference in magnetic permeability between the surface and near-surface defects of steel products (such as cracks, slag inclusions, hairline, etc.) and the magnetic permeability of steel. After magnetization, the magnetic field at the discontinuity of these materials will be distorted, forming a leakage magnetic field on the surface of the workpiece where some magnetic flux leaks, thereby attracting magnetic powder to form magnetic powder accumulation at the defects - magnetic traces. Under appropriate lighting conditions, the position and shape of the defects are revealed. By observing and interpreting the accumulation of these magnetic powders, magnetic particle inspection is realized. Magnetic particle inspection is mostly carried out by spraying a suspended magnetic powder liquid mixed with a suspension in a certain proportion on the surface of steel products.

After standing for a long time, the suspended magnetic powder liquid will precipitate and stratify, and the preparation quality will be abnormal, which will directly affect the magnetic particle inspection effect.

When the extrusion wheel stops squeezing the connecting plate, the connecting spring is reset to make the connecting plate move up and down, thereby making the connecting plate drive the stirring motor to move up and down, and the rotating shaft drives the stirring rod to stir up and down. At the same time, the rotation of the stirring motor drives the rotating shaft to rotate, causing the stirring rod to rotate and rotate the suspended magnetic powder liquid to stir, thereby avoiding sedimentation and stratification of the suspended magnetic powder liquid when it is left to stand, ensuring the quality of the suspended magnetic powder liquid, and preventing it from affecting the magnetic particle inspection effect.

[0018] 2. The magnetic powder spraying mechanism used for magnetic particle inspection drives the half gear to rotate by the rotation of the driving motor. When the half gear meshes with the inner rear part of the gear frame, the gear frame moves to the left.

As a result, the gear frame drives the T-block to move back and forth, causing the connecting pipe to move back and forth, thereby causing the spray head to spray back and forth left and right, avoiding dead angles in the spraying, ensuring uniform spraying, and preventing impact on the flaw detection effect.

The stirring mechanism 300 is connected to the top of the holding box 200. A pump 210 is fixedly connected to the middle of the front side of the top of the bottom plate 100. The outlet end of the pump 210 is fixedly connected to a hose 220. The inlet end of the pump 210 is fixedly connected to a liquid inlet pipe 230. An injection pipe 240 is fixedly connected to the middle of the front top of the holding box 200. A sealing plug 250 is connected to the top of the injection pipe 240. The outlet end of the hose 220 is fixedly connected to a connecting pipe 260. The outer side wall of the connecting pipe 260 is evenly fixedly connected to a nozzle 270.

[0033] To sum up, the rotation of the extrusion motor 380 drives the extrusion wheel 390 to rotate. When the extrusion wheel 390 squeezes the connecting plate 340, the connecting plate 340 is lowered, driving the connecting spring 330 to stretch. When the extrusion wheel 390 stops squeezing the connecting plate 340, the connecting spring 330 is reset, causing the connecting plate 340 to move back and forth, thereby causing the connecting plate 340 to drive the stirring motor 350 to move back and forth, causing the rotating shaft 360 to drive the stirring rod 370 to stir up and down. At the same time, the rotation of the stirring motor 350 drives the rotating shaft 360 to rotate, causing the stirring rod 370 to rotate, and rotating and stirring the suspended magnetic powder liquid, thereby avoiding sedimentation and stratification of the suspended magnetic powder liquid when it is left to stand, ensuring the quality of the suspended magnetic powder liquid, and preventing it from affecting the magnetic particle flaw detection effect.

[0035] Please refer again Figure 3 The upper and lower ends of the connecting spring 330 are fixedly connected to the inner top of the fixing frame 310 and the top of the connecting plate 340 respectively.

[0036] Please refer again Figure 3 The rotating shaft 360 passes through the top of the inner cavity of the containing box 200 , and the stirring rod 370 is located inside the containing box 200 .

[0037] Please refer again Figure 4 The top front side of the holding box 200 is fixedly connected to a swing mechanism 400, which includes a connecting rod 410, a mounting plate 420, a slide groove 430, a T-block 440, a gear frame 450, a mounting frame 460, a drive motor 470 and a half gear 480. The left and right parts of the top front of the holding box 200 are fixedly connected to the connecting rod 410, and the bottom of the left and right connecting rods 410 are fixedly connected to the mounting plate 420. Slide grooves 430 are provided on the left and right sides of the top of the mounting plate 420. The inside of the slide groove 430 is slidably connected to the T-block 440, and the top of the left and right T-blocks 440 is fixedly connected to the gear frame 450.

[0039] In summary, by driving the motor 470, the half gear 480 is driven to rotate. When the half gear 480 is engaged with the inner rear portion of the gear frame 450, the gear frame 450 moves to the left. When the half gear 480 is engaged with the inner front portion of the gear frame 450, the gear frame 450 moves to the right. As a result, the gear frame 450 drives the T-block 440 to move back and forth left and right, and the connecting pipe 260 to move back and forth left and right, so that the nozzle 270 sprays back and forth left and right, avoiding dead angles in spraying, making the spraying uniform, and preventing impact on the flaw detection effect.

[0040] When the extrusion wheel 390 is rotated, the extrusion motor 380 is rotated, and when the extrusion wheel 390 squeezes the connecting plate 340, the connecting plate 340 is lowered, and the connecting spring 330 is stretched. When the extrusion wheel 390 stops squeezing the connecting plate 340, the connecting spring 330 is reset to make the connecting plate 340 move back and forth, so that the connecting plate 340 drives the stirring motor 350 to move back and forth, and the rotating shaft 360 drives the stirring rod 370 to stir up and down. At the same time, the rotation of the stirring motor 350 drives the rotating shaft 360 to rotate, so that the stirring rod 370 is stirred up and down. 370 rotates to rotate and stir the suspended magnetic powder liquid. By starting the pump 210, the suspended magnetic powder liquid is transported into the connecting pipe 260 and sprayed out through the nozzle 270. The rotation of the drive motor 470 drives the half gear 480 to rotate. When the half gear 480 engages with the inner rear part of the gear frame 450, the gear frame 450 moves to the left. When the half gear 480 engages with the inner front part of the gear frame 450, the gear frame 450 moves to the right, thereby causing the gear frame 450 to drive the T-block 440 to move back and forth left and right, causing the connecting pipe 260 to move back and forth left and right, thereby causing the nozzle 270 to spray back and forth left and right, avoiding blind spots in spraying.
