Technical Field
[0001] The present invention relates to the technical field of metal detection, and in particular to an automated phased array mechanical arm flaw detection device and a detection method. Background Art
[0002] Ultrasonic phased array flaw detector is an advanced non-destructive testing equipment used to detect defects and structural problems inside single and composite materials. It uses ultrasonic propagation characteristics and phased array technology to achieve high-resolution detection. Phased array ultrasonic flaw detection is a high-precision and high-efficiency non-destructive testing technology widely used in aviation, aerospace, automobile, shipbuilding, petrochemical and other fields.
[0003] Compared with traditional ultrasonic flaw detection technology, phased array ultrasonic flaw detection has higher resolution, wider detection range and faster detection speed. The principle of phased array ultrasonic flaw detection is to use the characteristics of ultrasonic propagation in materials, transmit ultrasonic waves to the object to be tested through the probe, and then receive the reflected signal. According to the signal strength, time and phase information, the internal structure and defects of the object to be tested are calculated. The probe of phased array ultrasonic flaw detection is composed of multiple small ultrasonic transmitters and receivers. By controlling the phase and amplitude of each transmitter and receiver, the emission and reception direction of ultrasonic waves can be controlled, thereby realizing all-round detection of the object to be tested. The advantage of phased array ultrasonic flaw detection is that it can achieve high-precision defect detection and imaging, detect tiny defects and structural changes, and realize three-dimensional imaging of the object to be tested; the application range of phased array ultrasonic flaw detection is very wide, and it can be used for the detection and imaging of various materials such as metals, non-metals, and composite materials.

The rotating roller group 1 401 and the rotating roller group 2 402 cooperate with each other to support the material to be inspected, such as a plate or a pipe. When the material to be inspected is a plate, the rotating roller group 1 401 and the rotating roller group 2 402 may not rotate. When the material to be inspected is a pipe, the rotating roller group 1 401 and the rotating roller group 2 402 may drive the pipe to rotate, thereby facilitating comprehensive flaw detection of the pipe.
[0052] The rotating device 403 includes a rotating shaft 1 4031, a rotating shaft 2 4032, a driven sprocket 1 4033, a driven sprocket 2 4034, a synchronous chain 4035, a rotating sprocket 4036 and a driving motor 404.

[0053] The bottom of the flaw detection arm 5 is provided with a mounting plate 6, and first material defoaming mechanisms 7 are symmetrically arranged on both sides of the mounting plate 6. The ultrasonic probe 2 is located in the middle of the two first material defoaming mechanisms 7. When performing flaw detection, the flaw detection arm 5 drives the ultrasonic probe 2 to move into the water and is located on the upper side of the material to be detected. At this time, the first material defoaming mechanism 7 first contacts the material to be detected, and after the bubbles on the surface of the material to be detected are eliminated, the ultrasonic probe 2 is used to collect data, thereby avoiding errors caused by bubbles and improving the accuracy of flaw detection.
[0054] The first material defoaming mechanism 7 includes a sponge 701 and a height adjustment assembly, wherein the height adjustment assembly is arranged on the upper side of the mounting plate 6, and the sponge 701 is arranged on the lower side of the mounting plate 6. The connecting rod 704 of the height adjustment assembly penetrates the mounting plate 6 and is detachably connected to the sponge 701. The sponge 701 is detachably connected to the connecting rod 704 by a bolt assembly, so that the sponge 701 can be replaced after long-term use. The sponge 701 contacts and wipes the surface of the material to be detected, thereby eliminating bubbles on the surface of the material to be detected. By setting the height adjustment assembly, the height of the sponge 701 can be appropriately adjusted to prevent the sponge 701 from failing to contact the material to be detected, and is suitable for materials to be detected with different thicknesses.
[0055] The height adjustment assembly includes an internal threaded barrel 702, an external threaded barrel 703, a connecting rod 704, a limiting sleeve 705 and a height adjustment rod 706; the bottom of the internal threaded barrel 702 is rotatably connected to the mounting plate 6, the external threaded barrel 703 is threadedly connected to the inner side of the internal threaded barrel 702, the limiting sleeve 705 is arranged in the middle of the internal threaded barrel 702 and fixedly connected to the mounting plate 6, and the connecting rod 704 is slidably connected to the middle of the limiting sleeve 705. A limiting ring 707 is arranged on the top of the connecting rod 704, a rectangular limiting hole 708 extending to the middle of the connecting rod 704 is arranged in the middle of the limiting ring 707, and a rectangular limiting plate 709 slidably connected to the limiting hole 708 is arranged in the middle of the external threaded barrel 703. The limiting plate 709 cooperates with the limiting hole 708 to limit the external threaded barrel 703 so that it cannot rotate. When the internal threaded barrel 702 is rotated, the external threaded barrel 703 connected to it by threads can only move up and down.
[0056] A transverse through groove 710 is provided in the middle of the limiting sleeve 705, and an inclined through hole 711 is provided in the middle of the connecting rod 704. The height adjustment rod 706 is slidably connected with the through hole 711 and the through groove 710. The cross section of the height adjustment rod 706 is N-shaped. The inclined rod 7061 in the middle of the height adjustment rod 706 is slidably connected with the through hole 711. Both ends of the inclined rod 7061 pass through the through hole 711 and are connected with the vertical rod 7062. The vertical rod 7062 is slidably connected with the through groove 710. The side of the vertical rod 7062 away from the connecting rod 704 is provided with an inclined surface 1 7063, and the inclination directions of the two inclined surfaces 1 7063 are the same. The inner side of the external threaded cylinder 703 is provided with an inclined surface 2 7031 parallel to the inclined surface 1 7063.
[0057] The external threaded cylinder 703 moves up and down to drive the second inclined plane 7031 to move up and down. When the second inclined plane 7031 moves downward, the second inclined plane 7031 on the right side moves away from the first inclined plane 7063, and the second inclined plane 7031 on the left side pushes the first inclined plane 7063 to move rightward, thereby causing the inclined rod 7061 to move rightward, that is, the higher end of the inclined rod 7061 moves toward the through hole 711, thereby pushing the connecting rod 704 to move upward, thereby adjusting the height of the sponge 701. When the second inclined plane 7031 moves upward, the second inclined plane 7031 on the left side moves away from the first inclined plane 7063, and the second inclined plane 7031 on the right side pushes the first inclined plane 7063 to move leftward, thereby causing the inclined rod 7061 to move leftward, that is, the lower end of the inclined rod 7061 moves toward the through hole 711, thereby pushing the connecting rod 704 to move downward, thereby adjusting the height of the sponge 701.
[0058] The ultrasonic probe 2 is connected to the mounting plate 6 through the disassembly assembly 8, which is convenient for installing and replacing the ultrasonic probe 2 and improves its convenience of use. The disassembly assembly 8 includes a mounting block 801, which is fixedly connected to the mounting plate 6 and extends to the lower side of the mounting plate 6, a cable connector 802 is provided on the top of the mounting block 801, a fixing member 803 is threadedly connected to the bottom of the mounting block 801, a mounting cavity 804 is provided in the middle of the mounting block 801, a clamping member 805 is provided in the mounting cavity 804, a slot 806 is provided in the middle of the clamping member 805, the bottom end of the clamping member 805 is a conical platform structure and abuts against the fixing member 803, a fastening hole 807 is provided in the middle of the fixing member 803, the end of the fastening hole 807 is a conical hole matching the conical platform, a clamping hole is provided in the middle of the clamping member 805, and the clamping hole communicates with the fastening hole 807 to form a probe mounting hole.
[0059] During installation, the ultrasonic probe 2 is inserted into the probe installation hole, and the ultrasonic probe 2 is connected to the cable connector 802, and then the fixing piece 803 is tightened to move the tapered hole toward the tapered platform, and as the tapered hole and the tapered platform overlap, the slot 806 of the clamping piece 805 is contracted, thereby clamping the ultrasonic probe 2 and stably connecting it to the bottom of the mounting plate 6. During disassembly, the fixing piece 803 is screwed in the opposite direction to loosen the ultrasonic probe 2 with the clamping piece 805, which is simple and convenient.
[0060] One end of the support mechanism 4 is also provided with a probe defoaming mechanism 9, which includes a mounting seat 901, a mounting rod 902 is provided on the top of the mounting seat 901, and a sponge defoaming sleeve 903 is sleeved on the mounting rod 902. When the ultrasonic probe 2 is extended below the water surface, it is first moved to the probe defoaming mechanism 9, so that the ultrasonic probe 2 contacts the sponge defoaming sleeve 903, and the bubbles on the surface of the ultrasonic probe 2 are removed, so as to prevent the bubbles on the probe surface from affecting the flaw detection and further improve the accuracy of the flaw detection.
[0061] The support mechanism 4 is also provided with a second material defoaming mechanism 10, which is a flexible cylindrical rubber sleeve. The rotating roller group 1 401 and the rotating roller group 2 402 both include a plurality of rotating rollers connected in series, and the cylindrical rubber sleeve is mounted on the rotating rollers. When the material to be detected is a pipe, as the rotating roller group 1 401 and the rotating roller group 2 402 rotate, the cylindrical rubber sleeve contacts the surface of the pipe and squeezes and removes the bubbles on the surface of the pipe, preventing the first material defoaming mechanism 7 from being unable to remove the bubbles on the surface of the pipe in time due to the rolling of the pipe during the flaw detection process, thereby further improving the accuracy of the flaw detection and making it applicable to materials to be detected of different shapes.
[0062] Example 2
[0063] The detection method using the above-mentioned automated phased array mechanical arm flaw detection device comprises the following steps:
[0064] S1 puts the material to be tested into the flaw detection water tank 1 and locates it on the upper side of the support mechanism 4. When the material to be tested is a plate, the support mechanism 4 may not be started. When the material to be tested is a pipe, the pipe is placed between the rotating roller group 1 401 and the rotating roller group 2 402, and the rotating device 403 is started to make the rotating roller group 1 401 and the rotating roller group 2 402 drive the pipe to rotate, and remove the bubbles on the surface of the pipe through the second material defoaming mechanism 10.
[0065] Then, the position adjustment mechanism 3 is started, and the ultrasonic probe 2 is first moved to above the probe defoaming mechanism 9 , and after the ultrasonic probe 2 is inserted into the water, a defoaming treatment is performed at the probe defoaming mechanism 9 .
[0066] S2 moves the ultrasonic probe 2 to one end of the material to be detected, uses the first material defoaming mechanism 7 to defoam the surface of the material to be detected, and then uses the ultrasonic probe 2 to collect the flaw detection data of the material to be detected and perform preprocessing.
[0067] S3 transmits the flaw detection data to the data management system, analyzes the defect waveform, and combines and generates ultrasonic flaw detection results for feedback output.
[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
