Description

Technical Field

[0001] This invention relates to the field of ultrasonic testing technology, and in particular to a hardware ultrasonic testing device for multi-material additive manufacturing. Background Technology

[0002] Multimaterial additive manufacturing technology has developed rapidly in recent years, especially in industries such as aerospace, medical, automotive and electronics. In order to ensure the quality and reliability of multimaterial additive manufacturing parts, ultrasonic testing, as a non-destructive testing method, is widely used to detect internal defects and structural integrity of these parts.

[0003] Carbon fiber reinforced composite sheets are a type of hardware in the field of multi-material additive manufacturing technology. During the production process, carbon fiber reinforced composite sheets may be affected by various factors, such as the irregular shape and size of carbon fibers, the chemical reaction rate during the manufacturing process, the content of various elements, the amount and viscosity of resin, etc. These factors may lead to defects or damage in the product. Therefore, carbon fiber reinforced composite sheets need to be sampled and ultrasonically tested. Ultrasonic testing can effectively detect defects such as delamination, voids, and inclusions in carbon fiber reinforced composite sheets. Carbon fiber reinforced composite sheets can be manufactured into various shapes according to design requirements, such as arcs.

[0004] In existing technologies, ultrasonic testing of curved carbon fiber reinforced composite panels requires the application of coupling agent to both the testing surface of the panel and the probe. The panel is then manually moved to align with the ultrasonic probe. Since the probe's trajectory must remain in close contact with the panel, the central axis of the probe's trajectory must coincide with the central axis of the panel. This manual movement requires the use of positioning fixtures, making the process cumbersome. Furthermore, for curved carbon fiber reinforced composite panels of different diameters, the probe's trajectory must be modified, further compromising work efficiency. Summary of the Invention

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0031] See Figure 1 and Figure 6 An ultrasonic testing device for multi-material additive manufacturing hardware includes a working panel 1 and a bottom support plate 11 symmetrically fixedly connected to the lower side of the working panel 1. The working panel 1 has a third movable opening 15, a second movable opening 14 and a first movable opening 13 symmetrically distributed from the center to the side. The working panel 1 also has a support plate 12 symmetrically fixedly connected to the lower side of the working panel 1. The upper side of the working panel 1 is provided with an axis adjustment mechanism 2 for adjusting the position of the central axis of the arc-shaped carbon fiber reinforced composite material. Above the axis adjustment mechanism 2 is a testing mechanism 3 for ultrasonic testing of the arc-shaped carbon fiber reinforced composite material.

[0032] See Figure 1 , Figure 2 and Figure 6 The axis-aligning mechanism 2 includes an inner support component 22 disposed at the center of the upper side of the working panel 1 for supporting the inner wall of the arc-shaped carbon fiber reinforced composite plate to change the position of the central axis of the arc-shaped carbon fiber reinforced composite plate, and a locking component 21 disposed in the third movable opening 15 on both sides for locking the front and rear ends of the arc-shaped carbon fiber reinforced composite plate.

[0033] See Figure 1 and Figure 4The detection mechanism 3 includes an ultrasonic detection probe 31 that is perpendicular to the central axis of the arc-shaped carbon fiber reinforced composite plate and movably mounted above the working panel 1. The ultrasonic detection probe 31 is fixedly connected to the mounting block 32, and the mounting block 32 is fixedly connected to the output end of the electric push rod 33. The electric push rod 33 is provided with a rotating component 34 for controlling its rotation around the central axis of the arc-shaped carbon fiber reinforced composite plate. The rotating component 34 includes an arc-shaped seat 341 located behind the ultrasonic detection probe 31. The left and right ends of the arc-shaped seat 341 are provided with translation components 35 for controlling its forward and backward movement.

[0034] In actual operation, the installation block 32 is controlled by the electric push rod 33 to drive the ultrasonic detection probe 31 to approach the surface of the arc-shaped carbon fiber reinforced composite board, so as to meet the contact effect of the ultrasonic detection probe 31 with arc-shaped carbon fiber reinforced composite boards of different diameters.

[0035] By using the shaft mechanism 2 and the detection mechanism 3 in combination, the alignment and detection of the arc-shaped carbon fiber reinforced composite plate can be completed automatically.

[0036] See Figure 1 , Figure 6 and Figure 7 The locking assembly 21 includes abutment plates 211 that are symmetrically slidably connected to the second movable opening 14 on the same side. The lower ends of the two abutment plates 211, which are symmetrically distributed on the front and rear sides, are fixedly connected to the same movable plate 213. The front and rear movable plates 213 are symmetrically threaded to the bidirectional lead screw 212 and slidably connected to the guide rod 214. The bidirectional lead screw 212 is rotatably connected between the front and rear support plates 12. The guide rod 214 is fixedly connected between the front and rear support plates 12. The front end of the bidirectional lead screw 212 extends to the outside of the front support plate 12 and is fixedly connected to the output end of the motor 215. The motor 215 is fixedly connected to the front support plate 12.

[0037] In actual operation, the motor 215 drives the bidirectional lead screw 212 to rotate, and the bidirectional lead screw 212 controls the front and rear moving plates 213 to drive the clamping plate 211 to move in opposite directions along the guide rod 214. The clamping plate 211 clamps the front and rear ends of the arc-shaped carbon fiber reinforced composite plate to ensure the concentricity of the arc-shaped carbon fiber reinforced composite plate and the arc-shaped seat 341.

[0038] See Figure 1 and Figure 2The inner support assembly 22 includes a mounting base 224 fixedly connected to the center position of the working panel 1. The upper end of the mounting base 224 is symmetrically rotatably connected to a rotating shaft 223. The front and rear ends of the rotating shaft 223 are fixedly connected to connecting arms 222. The ends of the front and rear connecting arms 222 on the same rotating shaft 223 away from the rotating shaft 223 are rotatably connected to a support roller 221. The front ends of the left and right rotating shafts 223 are jointly provided with an adjustment component 226 for controlling their rotation. The left and right second movable openings 14 are jointly provided with a secondary adjustment component 225 for adjusting the left and right ends of the arc-shaped carbon fiber reinforced composite plate to the same height.

[0039] See Figure 3 The adjusting component 226 includes a rotating gear 2262 fixedly connected to the front end of the left and right rotating shafts 223. The left and right rotating gears 2262 are meshed together with a double-sided rack 2261. The upper end of the double-sided rack 2261 is fixedly connected to the output end of the electric push rod 2263. The electric push rod 2263 is fixedly connected to the working panel 1.

[0040] See Figure 2 , Figure 5 and Figure 6 The secondary adjustment component 225 includes a support plate 2251 embedded in the second movable opening 14. A bottom connecting plate 2252 is fixedly connected to the center of the lower side of the support plate 2251. A connecting plate 2254 is fixedly connected between the bottom connecting plates 2252 on the left and right sides. The lower side of the connecting plate 2254 is fixedly connected to the output end of a plurality of electric push rods 2255. The plurality of electric push rods 2255 are fixedly connected to the connecting plate 2253. The connecting plate 2253 is fixedly connected between the left and right bottom support plates 11.

[0041] In actual operation, the electric push rod 2263 controls the up-and-down movement of the double-sided rack 2261, which in turn controls the rotation of the gears 2262 on both sides. The gears 2262, through the rotating shaft 223, control the connecting arm 222 to drive the support roller 221 to revolve around the rotating shaft 223, thereby changing the height of the support roller 221. When adjusting the height of the support roller 221, after the support roller 221 contacts the inner wall of the arc-shaped carbon fiber reinforced composite board, the height of the support roller 221 is further increased. If the arc-shaped carbon fiber reinforced composite board... The central axis of the material is not located on the left-right central axis surface of the working panel 1. The inner wall of the arc-shaped carbon fiber reinforced composite plate will only contact one side of the support roller 221. As the support roller 221 is raised, the arc-shaped carbon fiber reinforced composite plate will tilt slightly when it contacts both support rollers 221 at the same time, that is, the heights of the left and right ends are different. Then, the electric push rod 2255 controls the connecting plate 2254 to drive the bottom connecting plate 2252 to lift the support plate 2251. The support plate 2251 that first contacts the lower end of the arc-shaped carbon fiber reinforced composite plate will continuously... Raise the lower end of the curved carbon fiber reinforced composite plate, and the two side support rollers 221 roll and rotate the curved carbon fiber reinforced composite plate until the two side support plates 2251 and the two ends of the curved carbon fiber reinforced composite plate contact simultaneously. The curved carbon fiber reinforced composite plate can then achieve the centering effect in the left and right directions. Before testing, the central axis of the curved seat 341 and the curved carbon fiber reinforced composite plate needs to be aligned. After the left and right directions are aligned, the alignment of the central axis is performed. Given the distance S from the top of the curved seat 341 to the working panel 1, and the diameters R1 and R2 of the curved carbon fiber reinforced composite plate and the curved seat 341, first remove the support of the support rollers 221, and then move the curved carbon fiber reinforced composite plate upward as a whole through the support plate 2251. Measure the distance M from the top of the curved carbon fiber reinforced composite plate to the working panel 1 with a ruler. Continue moving upward until R1-M = R2-S, indicating that the central axis of the curved carbon fiber reinforced composite plate and the curved seat 341 are aligned. Then stop moving the support plate 2251 upward.

[0042] See Figure 4 The core assembly 34 includes an arch frame 347 fixedly connected to the rear side of the electric push rod 33. A roller 342 is rotatably connected to the upper side inside the arch frame 347. An arc-shaped groove 3411 is provided on the arc-shaped seat 341. The roller 342 is limited and rolled in the arc-shaped groove 3411. A rotating rod 344 is rotatably connected to the lower side inside the arch frame 347. A self-propelled gear 345 is fixedly connected to the center of the rotating rod 344. The inner ring wall of the arc-shaped seat 341 passes through the arch frame 347 and a gear ring segment 346 is provided on the side of the arc-shaped seat 341 near the central axis. The gear ring segment 346 is meshed with the self-propelled gear 345. The rear end of the rotating rod 344 extends to the outside of the arch frame 347 and is fixedly connected to the output end of the motor 343. The motor 343 is fixedly connected to the outside of the arch frame 347.

[0043] In actual operation, the motor 343 controls the rotating rod 344 to drive the self-propelled gear 345 to rotate. The self-propelled gear 345 will then rotate around the central axis of the arc-shaped seat 341 along the gear ring segment 346. The self-propelled gear 345 will drive the ultrasonic detection probe 31 to rotate through the arch frame 347, so that the ultrasonic detection probe 31 can perform arc-shaped trajectory detection.

[0044] See Figure 6 and Figure 7 The translation component 35 includes movable blocks 351 fixedly connected to the lower sides of the left and right ends of the arc-shaped seat 341. The two movable blocks 351 pass through the first movable openings 13 on both sides and are respectively threaded to the translation screw 354 and slidably connected to the guide rod 353. The translation screw 354 is rotatably connected between the front and rear side support plates 12. The front end of the translation screw 354 extends to the outside of the front side support plate 12 and is fixedly connected to the output end of the motor 352. The motor 352 is fixedly connected to the front side support plate 12, and the guide rod 353 is fixedly connected between the front and rear side support plates 12.

[0045] In actual operation, the translation screw 354 is rotated by the motor 352, and the translation screw 354 drives the arc-shaped seat 341 to translate in the front and back direction through the moving block 351. After the ultrasonic detection probe 31 completes the detection of the current segment, the arc-shaped seat 341 performs translation work, and the translation distance is one body position of the ultrasonic detection probe 31.

[0046] See Figure 4 The ultrasonic testing probe 31 is a soft contact probe.

[0047] In practical applications, the soft contact probe has good adaptability and can fit closely to curved surfaces.

[0048] In use: S1: Place the curved carbon fiber reinforced composite board on the working panel 1. Then, control the double-sided rack 2261 to move up and down via the electric push rod 2263. The double-sided rack 2261 controls the rotation of the gears 2262 on both sides. The gears 2262 control the connecting arm 222 to drive the support roller 221 to revolve around the rotating shaft 223 via the rotating shaft 223, thereby changing the height of the support roller 221. When adjusting the height of the support roller 221, after the support roller 221 contacts the inner wall of the curved carbon fiber reinforced composite board, continue to raise the height of the support roller 221. If the central axis of the curved carbon fiber reinforced composite board... The line is not located on the left-right central axis of the working panel 1. The inner wall of the curved carbon fiber reinforced composite plate will only contact one side of the support roller 221. As the support roller 221 is raised, the curved carbon fiber reinforced composite plate will tilt slightly when it contacts both support rollers 221 at the same time, that is, the heights of the left and right ends are different. Then, the electric push rod 2255 controls the connecting plate 2254 to drive the bottom connecting plate 2252 to lift the support plate 2251. The support plate 2251 that first contacts the lower end of the curved carbon fiber reinforced composite plate will continuously raise the height of the lower end of the curved carbon fiber reinforced composite plate. The support rollers 221 on both sides will contact the curved carbon fiber... The reinforced composite plate is rotated until the two side support plates 2251 and both ends of the arc-shaped carbon fiber reinforced composite plate simultaneously contact each other, thus achieving centering in the left and right directions. Before testing, the central axis of the arc-shaped seat 341 and the arc-shaped carbon fiber reinforced composite plate needs to be aligned. After centering in the left and right directions, the alignment of the central axis is performed. Given the distance S from the top of the arc-shaped seat 341 to the working panel 1, and the diameters R1 and R2 of the arc-shaped carbon fiber reinforced composite plate and the arc-shaped seat 341, the support of the support roller 221 is removed first, and then the plate 2251 is rotated through the support plate 2251. 251 drives the arc-shaped carbon fiber reinforced composite plate to move upward as a whole. The distance M from the top of the arc-shaped carbon fiber reinforced composite plate to the working panel 1 is measured by a ruler. The upward movement continues until R1-M=R2-S, indicating that the central axis of the arc-shaped carbon fiber reinforced composite plate and the arc-shaped seat 341 coincides. Then the upward movement of the support plate 2251 is stopped. The bidirectional lead screw 212 is driven to rotate by the motor 215. The bidirectional lead screw 212 controls the front and rear side moving plates 213 to drive the pressing plate 211 to move in opposite directions along the guide rod 214. The pressing plate 211 presses against the front and rear ends of the arc-shaped carbon fiber reinforced composite plate.

[0049] S2: The translation screw 354 is rotated by the motor 352. The translation screw 354 drives the arc seat 341 to move in the front and back direction through the moving block 351. After moving to one end of the arc carbon fiber reinforced composite plate, the movement stops. Then, the installation block 32 is controlled by the electric push rod 33 to drive the ultrasonic detection probe 31 to approach the surface of the arc carbon fiber reinforced composite plate.

[0050] S3: The motor 343 controls the rotating rod 344 to drive the self-propelled gear 345 to rotate. The self-propelled gear 345 will rotate around the central axis of the arc-shaped seat 341 along the gear ring segment 346. The self-propelled gear 345 will drive the ultrasonic detection probe 31 to rotate through the arch frame 347, so that the ultrasonic detection probe 31 can detect the arc trajectory. After the ultrasonic detection probe 31 completes the detection of the current segment, the arc-shaped seat 341 will perform translation work. The translation distance is one body position of the ultrasonic detection probe 31, and then the detection of the arc trajectory of the ultrasonic detection probe 31 will continue again.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
