Description

Technical Field

[0001] The present invention relates to the technical field of additive manufacturing part detection, and specifically provides a water immersion ultrasonic detection device for additive manufacturing parts. Background Art

[0002] Additive manufacturing technology is a technology for manufacturing solid parts by gradually adding materials. Compared with the traditional material removal - cutting processing technology, it is a "bottom-up" manufacturing method. The manufactured parts need to be detected by ultrasonic waves.

[0003] Regular-shaped parts can be ultrasonically detected by applying a coupling agent to their surfaces. However, for parts with complex structures and irregular shapes, if they are still detected by applying a coupling agent, after the detection is completed, it is difficult to completely clean the coupling agent on their surfaces, and it is difficult for the coupling agent to enter and fill some positions, thus affecting the detection results. They cannot be detected by applying a coupling agent. Generally, they need to be immersed in water for detection. However, there are oil stains and impurities on the surfaces of the processed parts. If they are directly put into water for detection, the oil stains and impurities will affect the detection results, and only one part can be cleaned and detected at a time, resulting in low detection efficiency. For parts with complex structures, special fixtures need to be designed, which increases the detection cost. Summary of the Invention

[0015] It can be seen from the above technical solutions that the present invention has the following advantages:

[0016] 1.

By adjusting the distance and angle, the rubber airbags on the clamping plates are evenly in contact with the surface of the parts, so that the parts are evenly stressed, thereby achieving the purpose of clamping and fixing the parts.

[0018] 3. In the present invention, during the entire detection process, the foam water on the inner surface of the water tank in the middle can be sent to the water tank on the far right.

Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0031] Refer to Figure 1, An immersion ultrasonic testing device for additive manufacturing parts, comprising an ultrasonic transducer and a scanning device. Both the ultrasonic transducer and the scanning device are prior arts and are not shown in the drawings. The immersion ultrasonic testing device further includes a cleaning unit 1, a hanging assembly line 2, and a fixing unit 3. The hanging assembly line 2 is arranged on the cleaning unit 1 for transporting the parts fixed on the fixing unit 3. The fixing unit 3 is arranged at the lower end of the hanging assembly line 2 for fixing the parts to be tested. The cleaning unit 1 includes a fixed base 11. Vertically arranged plates 12 are symmetrically and fixedly installed on the upper end of the fixed base 11 from left to right. Horizontally arranged plates 13 are fixedly installed at the upper ends of the vertically arranged plates 12. The lower ends of the two horizontally arranged plates 13 on the left and right are fixedly connected to the hanging assembly line 2 together. Water tanks 14 are evenly and fixedly installed on the upper end of the fixed base 11 from left to right. A uniformly mixed cleaning liquid is contained in the rightmost water tank 14, and clear water is contained in the leftmost water tank 14 and the middle water tank 14. The fixing unit 3 includes a fixing plate 31. The hanging assembly line 2 is a prior art and runs intermittently through its own driving motor. Fixing plates 31 are evenly fixedly installed along the running track of the hanging chain belt on the hanging assembly line 2 at the lower end. Motors 1 32 are fixedly installed at the lower ends of the fixing plates 31. The output shaft of one of the motors 1 32 is fixedly installed with a distance control cylinder 1 33 through a coupling. The output shafts of the remaining motors 1 32 are fixedly installed with telescopic columns 34 through couplings.

When the suspension assembly line 2 drives the part to move into the rightmost water tank 14, the control member 35 is driven downward by the distance control cylinder 13, thereby driving the part into the rightmost water tank 14, and the part is driven to rotate by the motor 132 located just above the rightmost water tank 14, so that the detergent in the rightmost water tank 14 cleans the oil, rust and other impurities on the surface of the part. After cleaning, the distance control cylinder 13 drives the control member 35 to move upward, so that the cleaned part is moved out of the rightmost water tank 14, and the suspension assembly line 2 drives the part to continue moving , until the cleaned parts move to just above the middle water tank 14, the distance control cylinder 13 drives the control member 35 to continue to move downward, driving the parts downward into the middle water tank 14, at this time, the motor 132 located just above the middle water tank 14 is turned on to drive the parts to rotate, so that the clean water in the middle water tank 14 cleans the parts with foam attached to the surface. After cleaning, the distance control cylinder 13 drives the control member 35 to move upward, so that the cleaned parts are moved out of the middle water tank 14, and the hanging assembly line 2 drives the parts to move to the left again, until the completely cleaned parts move to just above the leftmost water tank 14, the distance control cylinder 13 drives the control member 35 to continue to move downward, driving the parts downward into the leftmost water tank 14.

[0033] At this time, immerse the ultrasonic transducer in the leftmost water tank 14, start the scanning device, and make the ultrasonic transducer scan the parts in the water according to the predetermined scanning path. After the detection is completed, continue to take the parts out of the leftmost water tank 14, and then take them out when they move to the rear side. During the entire movement of the hanging assembly line 2, the remaining parts to be inspected can be placed in the clamping member 36 that moves to the middle of the rear side for clamping and fixing to facilitate sustainable detection. When the parts to be inspected are structures with uniform shape but uneven quality, the clamping angle of the clamping member 36 is changed by the angle adjustment member 38 so that the parts are evenly stressed. When the parts to be inspected are structures with uneven shape and uneven quality, replace the clamping member 36 with an adjustable distance, and adjust the angle adjustment member 38 at the same time so that the parts are evenly stressed, so as to achieve the purpose of clamping and fixing the parts.

[0045] The working principle of the present invention: First, place the part to be detected between the four clamping plates 361 in the middle at the rear side. Drive the circular plate 353 to move downward through the distance control cylinder 352, thereby driving the inclined rod 359 to move downward. The cylindrical spring 3592 is compressed. The inclined block 3591 drives the right-angle plate 3593 to rotate towards the central axis side of the circular plate 353, thereby driving the clamping plate 361 to move towards the central axis side of the circular plate 353. The rubber airbag 362 on the clamping plate 361 is in close contact with the part, and the part is clamped and fixed. The suspension assembly line 2 starts to move. When the suspension assembly line 2 drives the part to move into the water tank 14 on the far right, drive the П-shaped support to move downward through the distance control cylinder 33, thereby driving the part to move downward until the part enters the water tank 14 on the far right. At this time, drive the part to rotate through the motor 32 directly above the water tank 14 on the far right, so that the cleaning agent in the water tank 14 on the far right can clean the oil stains, rust and other impurities on the surface of the part.

[0046] After the cleaning is completed, the spacing control cylinder 1-33 drives the П-shaped bracket to move upward, so that the cleaned parts are moved out of the rightmost water tank 14. The hanging assembly line 2 drives the parts to continue moving until the cleaned parts move to directly above the middle water tank 14. The spacing control cylinder 1-33 drives the П-shaped bracket to continue moving downward, driving the parts to enter the middle water tank 14 downward. At this time, the motor 1-32 located directly above the middle water tank 14 drives the parts to rotate, so that the clear water in the middle water tank 14 cleans the parts with foam attached to the surface.

[0047] After the cleaning is completed, the spacing control cylinder 1-33 drives the П-shaped bracket to move upward, so that the cleaned parts are moved out of the middle water tank 14. The hanging assembly line 2 drives the parts to continue moving until the completely cleaned parts move to directly above the leftmost water tank 14. The spacing control cylinder 1-33 drives the П-shaped bracket to continue moving downward, driving the parts to enter the leftmost water tank 14 downward. At this time, the ultrasonic transducer is immersed in the leftmost water tank 14, and the scanning device is started, so that the ultrasonic transducer scans the parts in the water according to a predetermined scanning path. After the detection is completed, the parts are taken out continuously, and then taken off when they move to the rear side. During the entire movement process of the hanging assembly line 2, the remaining parts to be detected can be placed between the four clamping plates 361 in the middle of the rear side for clamping and fixing, so as to facilitate the sustainable detection work. The principle of immersion ultrasonic testing is prior art and will not be elaborated here.

[0048] When the parts to be detected are of a regular shape but uneven in mass, the angle between the clamping plates 361 is adjusted by rotating the internal thread tube 383, thereby changing the forces borne by the four clamping plates 361 to make the parts evenly stressed. When the parts to be detected are of an irregular shape and uneven in mass, the adjustable-distance clamping plates 361 are replaced. By adjusting the distance and angle, the rubber air bags 362 on the clamping plates 361 are all in contact with the surface of the parts to make the parts evenly stressed, so as to achieve the purpose of clamping and fixing the parts.

[0049] During the entire detection process, the foamed water on the inner surface of the middle water tank 14 can be sent into the rightmost water tank 14. The return pipe 142 on the rightmost water tank 14 filters the water in the water tank 14. The leftmost water tank 14 replenishes the water lacking in the middle water tank 14 through the water supply pipe 151 and the water pump 3-152. When the water in the rightmost water tank 14 is too much, the water is discharged through the drain pipe 144, and the lacking water is introduced into the leftmost water tank 14 through the water inlet pipe 149.
