An ultrasonic testing device for additively manufactured parts

Abstract

The present invention relates to the technical field of ultrasonic detection of additively manufactured parts, and specifically to an ultrasonic detection device for additively manufactured parts, comprising an extrusion rack, a dust removal agent rack, a coating agent rack and an wiping agent rack. The present invention drives the dust removal agent rack and the coating agent rack to remove dust from the surface of a propeller through the extrusion rack, and coats the dust-removed propeller surface with a coupling agent, thereby ensuring that the propeller surface is quickly and evenly coated with the coupling agent. The wiping agent rack is driven downward by the extrusion rack to wipe the coupling agent on the propeller surface. The extrusion rack drives the dust removal agent rack to move downward to a position where the coating agent rack is higher than the wiping agent rack, and then blows air on the wiped propeller surface. During the entire detection process, the speed of coating the coupling agent and wiping the coupling agent on the propeller is accelerated, thereby improving the detection efficiency, while ensuring that the propeller surface is quickly and evenly coated with the coupling agent.

Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic detection of additively manufactured parts, and in particular to an ultrasonic detection device for additively manufactured parts. Background Art

[0002] Additive manufacturing technology is a technology that uses the method of gradually accumulating materials to manufacture solid parts. Compared with traditional material removal-cutting processing technology, it is a "bottom-up" manufacturing method. Based on different classification principles and understanding methods, additive manufacturing technology also has many names such as rapid prototyping, rapid forming, rapid manufacturing, 3D printing, etc. Here we mainly focus on metal parts propellers manufactured by additive manufacturing.

[0003] A propeller is a device that converts the engine's rotational power into propulsion by rotating blades in the air or water. It may have two or more blades connected to the hub, and the rearward side of the blade is a spiral surface or a propeller that is close to a spiral surface. Additively manufactured propellers need to be ultrasonically tested to determine whether their quality meets the standards.

[0004] The traditional detection method is to place the propeller on a flat surface, and then manually brush the coupling agent onto the surface of the propeller blades, and then use an ultrasonic detection probe to perform multi-point detection on the propeller surface, and remove the coupling agent on the surface of the propeller that has passed the detection. However, during the whole process, since the propeller has more blades, the brushing workload is large, and each detection time is long. In addition, manual brushing of the coupling agent can easily lead to a large difference in the thickness of the coupling agent on the blade surface. During subsequent inspections, the probe cannot obtain accurate test results when detecting this area, which affects the judgment result of the propeller quality, and puts the propeller that does not meet the standards into use, causing certain hazards. After the inspection, the coupling agent on the propeller surface needs to be wiped manually, and the wiping workload is large, which further increases the detection time, thereby reducing the detection efficiency.

[0047] The working principle of the present invention is as follows: first, the manufactured propeller is placed on the circular plate 34, and the middle part of the propeller is preliminarily positioned by the matching column 37. Then, the fan-shaped plate 39 is driven to move toward each other by rotating the bidirectional screw 38, and the propeller is clamped and positioned so that it is centered. The propeller is transported to the right by the chain plate conveyor 2. At this time, the extrusion block 182 is driven downward by the distance control cylinder 181 on the left to squeeze the arc plate 121 on the left and move downward, thereby driving the rectangular air outlet cylinder 134 and the cylindrical brush 147 to move downward, and gas is introduced into the rectangular air outlet cylinder 134 through the air pump 133 to blow away the dust on the surface of the propeller that has stopped rotating and moved to the right. At this time, the circular plate 34 is driven to rotate by the stepping motor 1 32, thereby driving the propeller transported to the right to rotate along the central axis of the matching column 37, and then the agent delivery column 144 is driven to rotate by the motor 2 145 to bring the coupling agent. The agent box 135 is discharged, and the distance between the scraper plate 142 and the agent delivery column 144 is adjusted by rotating the threaded rod 141, so as to control the thickness of the coupling agent on the surface of the agent delivery column 144, and the coupling agent is attached to the surface of the silicone sleeve 148 on the cylindrical coating 147 through the agent delivery column 144, and the coupling agent on the surface of the silicone sleeve 148 is coated on the surface of the rotating and rightward moving propeller. During the coating process, the propeller rotates with the circular plate 34 and is subjected to friction to generate a rotational force in the opposite direction, so that after rotating to a certain position on the circular plate 34, the propeller is blocked by the cylindrical block 36 and cannot continue to rotate, ensuring that the propeller is stationary for a long time after being subjected to friction, thereby ensuring that the propeller surface is completely coated with coupling agent. When the propeller moves to the middle of the workbench 1, the ultrasonic detector 19 is used to perform ultrasonic detection on the static propeller surface. The principle of ultrasonic detection is a prior art and will not be repeated here.

[0048] For the propeller that has passed the ultrasonic test, it is conveyed to the left by the chain conveyor 2, and the propeller continues to rotate. At this time, the right-side distance control cylinder 181 drives the extrusion block 182 to press down, and the left-side distance control cylinder 181 drives the extrusion block 182 to move up so that the arc plate 121 on the right is squeezed and moved downward, driving the wiping column brush 159 to move downward, thereby driving the wiping cotton cloth 1591 to wipe the coupling agent on the surface of the rotating propeller. When the rotating propeller moves to the bottom of the rectangular air outlet 134 on the left, the left-side distance control cylinder 181 drives the extrusion block 182 to move downward to ensure that the cylindrical coating brush 147 is higher than the wiping column brush 159. At this time, the propeller surface is blown through the rectangular air outlet 134. For the propeller that has failed the ultrasonic test, it can be directly removed without wiping and air drying. The wiping cotton cloth 159 on the wiping column brush 159 is wiped by the scraper plate 155. 1 to scrape off the coupling agent attached to the surface of the scraper plate 155 to prevent it from attaching the coupling agent to the propeller surface again. When there is a lot of coupling agent on the surface of the scraper plate 155, manually lift the control plate 158 on that side. At this time, the round head column block 163 is forced to enter the limit groove 161, the extrusion spring 162 is compressed, and the control plate 158 moves up to drive the scraper plate 155 to be tilted, so that the scraper plate 155 moves toward the scraper block 172 to prevent the scraper plate 155 from attaching too much coupling agent to the surface of the wiping column brush 159 during the movement. Then, pull the control plate 158 toward the scraper block 172 to move the scraper plate 155 toward the scraper block 172 until the scraper plate 155 cannot be moved. At this time, put down the control plate 158 and move it toward the middle of the workbench 1 to make the trapezoidal groove 173 in the middle of the scraper block 172 scrape off the coupling agent attached to the surface of the scraper plate 155.
