Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flaw detection, in particular to a flaw detection device for electric power metal parts. Background Art

[0002] Ultrasonic flaw detection is a method of inspecting defects in parts by using the characteristic that ultrasound can penetrate deep into metal materials and reflect at the edge of the interface when entering from one section to another. When the ultrasonic beam passes from the surface of the part through the probe into the metal, it generates reflected waves when encountering defects and the bottom of the part, forming pulse waveforms on the fluorescent screen. The location and size of the defects are determined based on these pulse waveforms.

[0003] The existing patent with publication number CN218629659U discloses a flaw detection device for electric metal parts, which can limit the electric metal parts and reduce shaking, but it can only detect from directly above the electric metal parts. There is a problem of fixed detection angle, which leads to incomplete detection results, and the signal attenuation during ultrasonic detection. Due to the thickness of the electric metal parts, sometimes flaw detection from only one side will lose its effect after exceeding the detection critical value. Therefore, the staff needs to disassemble the fixed electric metal parts first, then turn them over and then re-fix them, which is not convenient. Based on this, we propose an improved flaw detection device for electric metal parts. Utility Model Content

A mounting plate 17 is fixedly connected to the lower end of the driving slider 16. The flaw detector 18 is fixedly connected to the lower end of the mounting plate 17.

[0026] One side of the fixed clamping plate 4 is fixedly connected with a sliding plate 5. The movable clamping plate 7 is slidably sleeved on the outer wall of the sliding plate 5. The other end of the fixed clamping plate 4 is fixedly connected with an auxiliary shaft 3. The other end of the movable clamping plate 7 is rotatably sleeved with an adjusting screw 6.

A rotating sleeve 27 is rotatably sleeved in one of the fixing plates 2. The adjusting screw 6 is threadedly sleeved in the rotating sleeve 27.

[0027] In this embodiment, a driven shaft 19 is rotatably sleeved in the driving slider 16. Both ends of the driven shaft 19 penetrate through the driving slider 16 and are fixedly sleeved with traveling gears 20. Both of the two traveling gears 20 are engaged with the lower end of the arc-shaped gear ring 14. Using this relationship, the driving slider 16 can perform an arc-shaped movement at the lower end of the arc-shaped gear ring 14.

[0028] In this embodiment, a bevel gear one 21 is fixedly sleeved on the outer wall of the driven shaft 19 near the middle. A motor one is fixedly arranged on one side outer wall of the driving slider 16. The output end of the motor one penetrates through the driving slider 16 and is fixedly sleeved with a bevel gear two 22. The bevel gear one 21 and the bevel gear two 22 are engaged. Starting the motor one to drive the bevel gear two 22 to rotate can drive the bevel gear one 21 to rotate, and then drive the driven shaft 19 to rotate, and further drive the traveling gears 20 to rotate.

[0029] In this embodiment, a rotating wheel is fixedly sleeved at one end of the adjusting screw 6 away from the movable clamping plate 7. It is convenient to drive the adjusting screw 6 to rotate through the rotating wheel. The rotating direction of the movable clamping plate 7 is the same as the screwing-in direction of the adjusting screw 6 relative to the rotating sleeve 27, avoiding loosening of the adjusting screw 6 when the fixed clamping plate 4 and the movable clamping plate 7 drive the power metal component to flip, resulting in the clamping force of the clamping plate being lost and the power metal component falling off.

[0030] In this embodiment, a motor two is fixedly arranged on the outer wall of one of the fixing plates 2. The output end of the motor two penetrates through the fixing plate 2 and is fixedly sleeved with a spur gear one 23. One end of the auxiliary shaft 3 penetrates through the fixing plate 2 and is fixedly sleeved with a spur gear two 24. The spur gear one 23 and the spur gear two 24 are engaged.

[0031] In this embodiment, one side of the upper end surface of the installation table 1 is fixedly connected with a support plate 8. One side of the outer wall of the support plate 8 near the upper end is fixedly connected with a guide plate 9. A cylinder 10 and a slide bar 11 are respectively fixedly sleeved and slidably sleeved in the guide plate 9. The output end of the cylinder 10 and the other end of the slide bar 11 are fixedly connected with a connecting plate 12. The cylinder 10 can control the connecting plate 12 to move horizontally, so as to conveniently drive the flaw detector head 18 to move horizontally.

[0032] In this embodiment, a lifting groove is formed on one side of the outer wall of the support plate 8. A lifting rod is fixedly connected between the upper and lower inner walls of the lifting groove. A guide slider 26 is slidably sleeved on the outer wall of the lifting rod. An inclined strut 25 is hinged between one side of the lower end surface of the connecting plate 12 and the outer wall of the guide slider 26. The inclined strut 25 is used to strengthen the supporting strength of the connecting plate 12.

[0033] It should be noted that the present utility model is a flaw detection device for power metal components. When in use, the power metal component is placed on the sliding plate 5. Then, one hand fixes the rotating sleeve 27, and the other hand rotates the rotating wheel to drive the adjusting screw rod 6 to extend relative to the rotating sleeve 27, thereby driving the moving clamping plate 7 to move, and cooperating with the fixed clamping plate 4 to clamp and fix the power metal component. Then, the cylinder 10 drives the connecting plate 12 to extend, and at the same time, the power cylinder 13 drives the arc-shaped gear ring 14 to descend to a suitable height. Then, detection is carried out through the flaw detector head 18. During the detection process, driving the bevel gear II 22 to rotate by the motor I can drive the bevel gear I 21 to rotate, and then drive the two traveling gears 20 to rotate through the driven shaft 19. Due to its meshing relationship with the arc-shaped gear ring 14, the flaw detector head 18 can be adjusted to rotate in an arc, so as to conveniently detect the power metal component from multiple angles. When the thickness of the power metal component is large and accurate detection cannot be carried out only from above, the motor II can be started to drive the spur gear I 23 to rotate, and then drive the spur gear II 24 to rotate, and then drive the fixed clamping plate 4 to rotate through the auxiliary shaft 3, and then drive the moving clamping plate 7 to rotate synchronously through the sliding plate 5, so as to complete the flipping of the power metal component and facilitate the detection of its lower part, which is convenient and labor-saving and improves the comprehensiveness of detection.
