Description

Technical Field

[0001] The present invention relates to the field of ultrasonic detection technology, and in particular to a multi-material additive manufacturing hardware ultrasonic detection device. Background Art

[0002] Multi-material additive manufacturing technology has developed rapidly in recent years, especially in the aerospace, medical, automotive and electronics industries. In order to ensure the quality and reliability of multi-material additively manufactured 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 plates are a type of hardware in the field of multi-material additive manufacturing technology. Carbon fiber reinforced composite plates may be affected by various factors during the production process, such as the irregular shape and size of carbon fiber, the chemical reaction rate during the production process, the occupancy of various elements, the amount and viscosity of resin, etc. These may lead to defects or damage in the product. Therefore, carbon fiber reinforced composite plates need to be sampled and ultrasonically tested. Ultrasonic testing can effectively detect defects such as delamination, voids, and inclusions in carbon fiber reinforced composite plates. Carbon fiber reinforced composite plates can be manufactured into various shapes according to design requirements, such as arcs.

[0004] In the prior art, when ultrasonic testing is performed on a curved carbon fiber reinforced composite plate, a coupling agent needs to be applied to the test surface of the curved carbon fiber reinforced composite plate and the probe in advance, and then the curved carbon fiber reinforced composite plate is aligned at the position of the ultrasonic detection probe by manual movement. Since the motion trajectory of the ultrasonic detection probe needs to be in close contact with the curved carbon fiber reinforced composite plate, the central axis of the motion trajectory of the ultrasonic detection probe needs to coincide with the central axis of the curved carbon fiber reinforced composite plate. The manual movement method requires the use of some positioning tooling, which is more troublesome to operate. In addition, for curved carbon fiber reinforced composite plates of different diameters, the motion trajectory of the ultrasonic detection probe needs to be modified separately, and the work efficiency needs to be improved.

[0039] See also 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, and a double-sided rack 2261 is meshed and connected between the rotating gears 2262 on the left and right sides. The upper end of the double-sided rack 2261 is fixedly connected to the output end of the electric push rod 2263, and the electric push rod 2263 is fixedly connected to the working panel 1.

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 plate, the height of the support roller 221 is continuously increased. If the curved carbon fiber reinforced composite plate The center axis of the material is not on the left and right center axis plane of the working panel 1, and the inner wall of the arc-shaped carbon fiber reinforced composite plate will only contact the support roller 221 on one side. As the support roller 221 is raised, the arc-shaped carbon fiber reinforced composite plate will tilt slightly when it contacts the two support rollers 221 at the same time, that is, the heights of the left and right ends are different.

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.

[0044] See also Figure 6 and Figure 7 The translation assembly 35 includes a moving block 351 fixedly connected to the lower sides of the left and right ends of the arc seat 341.

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 sheet, continue to increase the height of the support roller 221. If the center axis of the arc-shaped carbon fiber reinforced composite sheet is The line is not on the left and right central axis of the working panel 1, and the inner wall of the arc-shaped carbon fiber reinforced composite plate will only contact the support roller 221 on one side. As the support roller 221 is raised, the arc-shaped carbon fiber reinforced composite plate will tilt slightly when it contacts the two support rollers 221 at the same time, that is, the heights of the left and right ends are different. Then, the electric push rod 1 2255 controls the connecting plate 2254 to drive the bottom connecting plate 2252 to lift the supporting plate 2251.

Under known circumstances, the distance S from the top of the arc-shaped seat 341 to the working panel 1, the diameters R1 and R2 of the arc-shaped carbon fiber reinforced composite plate and the arc-shaped seat 341, first remove the support of the support roller 221, and then pass the support plate 2 251 drives the arc-shaped carbon fiber reinforced composite plate to move upward as a whole, and measures the distance M from the top of the arc-shaped carbon fiber reinforced composite plate to the working panel 1 by a ruler. When the upward movement continues until R1-M=R2-S, it indicates that the central axis of the arc-shaped carbon fiber reinforced composite plate and the arc seat 341 coincide with each other, and then stops the upward movement of the support plate 2251, and drives the bidirectional screw rod 212 to rotate by the motor 1 215.

After moving to one end of the arc-shaped carbon fiber reinforced composite plate, the movement stops, and then the installation block 32 is controlled by the electric push rod 3 33 to drive the ultrasonic detection probe 31 to approach the surface of the arc-shaped carbon fiber reinforced composite plate.
