Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy quality inspection technology, specifically to a device for inspecting the flaring of the fusion joint of ultra-large diameter aluminum alloy pipes. Background Technology

[0002] In the production and processing of aluminum alloy tubing, especially for ultra-large diameter tubing, the quality of the fusion joint directly determines the overall performance and service life of the tubing. Ultra-large diameter aluminum alloy tubing, due to its excellent strength, corrosion resistance, and lightweight properties, is widely used in aerospace, shipbuilding, petrochemical, and rail transportation industries. These fields have extremely high requirements for the strength, corrosion resistance, and sealing performance of the tubing. As a critical component, the quality of the fusion joint directly affects the reliability and safety of the tubing; therefore, quality inspection of the fusion joint is an indispensable part of the production process.

[0003] Traditional inspection methods have many limitations. Macroscopic metallographic testing observes surface defects in the weld joint after corrosion, but it cannot inspect internal quality and is easily affected by subjective human factors. Ultrasonic testing uses the propagation characteristics of sound waves to inspect internal defects, but it requires highly skilled operators, can only inspect both ends of the pipe, and is inefficient for ultra-large diameter pipes, failing to provide comprehensive coverage. X-ray testing can visualize internal defects, but the equipment is expensive, slow, and poses radiation safety hazards. Furthermore, the inspection process for weld joints is complex, involving corrosion, marking, sawing, and compression testing, which affects inspection efficiency.

[0004] Currently, traditional inspection methods are insufficient for effectively testing the welding performance of fusion joints. With the widespread application of aluminum alloy tubing in high-end manufacturing, the requirements for fusion joint quality are increasingly stringent. However, existing inspection methods are inadequate for the inspection needs of ultra-large diameter aluminum alloy tubing, especially for testing the welding performance of fusion joints, where efficient and accurate methods are lacking. Therefore, developing an inspection device for flaring fusion joints of ultra-large diameter aluminum alloy tubing is of significant practical importance and application value for improving inspection efficiency and ensuring tubing quality.

[0021] This embodiment provides a device for inspecting the flaring of the fusion joint of ultra-large diameter aluminum alloy pipes, such as... Figure 1 As shown, it includes a main structure 1, a fixing ring 2, a flaring mechanism, a mounting mechanism, a planetary gear device, a transmission device, and a motor 7. The main structure 1 is equipped with a worktable 1-1, and the fixing ring 2 is set on the upper surface of the worktable 1-1. The fixing ring 2 is fixedly connected to the upper surface of the worktable 1-1, and the worktable 1-1 provides a stable support foundation for the entire fixing ring 2, ensuring the stability of the fixing ring 2; as shown... Figure 2As shown, the upper part of the fixed ring 2 is provided with multiple radially arranged first expanding through holes 2-1. The flaring mechanism includes multiple expanding tools 3, which pass through the first expanding through holes 2-1 and are slidably connected to the fixed ring 2. The first expanding through holes 2-1 facilitate the installation and sliding connection of the expanding tools 3, and serve to fix and guide the expanding tools 3. Each expanding tool 3 has a first gear part 3-1 on one side, and each expanding tool 3 has a flaring head 4 at the end away from the center of the fixed ring 2. The flaring head 4 is used for uniform expansion inspection of aluminum alloy tubes. The mounting mechanism is located inside the fixed ring 2 and is connected to the fixed ring 2. The planetary gear device includes multiple planetary gears 5, which are all connected to the mounting mechanism, and each planetary gear 5 meshes with the corresponding first gear part 3-1. The transmission device includes a transmission disc and a transmission mechanism that are connected to each other. Gear 6 and transmission disc are located below the mounting mechanism. The transmission gear 6 is located on the radial inner side of the fixed ring 2 and meshes with the planetary gear 5. Motor 7 is located inside the main structure 1. The upper end of the motor shaft 7-1 of motor 7 is connected to the center of the transmission disc, providing power for the entire device and driving the flaring inspection. The rotation of the motor shaft 7-1 of motor 7 drives the transmission disc to rotate, and the planetary gear 5 rotates synchronously. When the planetary gear 5 rotates, it can transmit the power of the motor to multiple planetary gears 5 at the same time, realizing the conversion and transmission of power and ensuring the smooth progress of the flaring inspection. Each planetary gear 5 drives the flaring tool 3 meshing with it to move synchronously. The flaring tool 3 converts the rotational motion into linear motion. Each flaring tool 3 synchronously and directly drives the flaring head 4 located at its end to move, realizing the flaring inspection of aluminum alloy pipes.

[0022] As a preferred embodiment, the upper surface of the workbench 1-1 is provided with a circular groove, and the mounting mechanism and transmission disk are set in the circular groove, which saves space and improves overall stability. The workbench 1-1 is provided with a through hole at the center of the circular groove, and the upper end of the motor shaft 7-1 passes through the through hole and is connected to the center of the transmission disk.

[0023] As a preferred embodiment of this example, specifically, such as Figure 1 and Figure 2As shown, the mounting mechanism includes a mounting disc 8, a mounting ring 9, and a mounting shaft 10. The mounting disc 8 is positioned above the transmission disc, and multiple planetary gears 5 are mounted on the upper surface of the mounting disc 8.

The mounting ring 9 is connected to the fixed ring 2 via a first connecting plate 11, which stabilizes the position of the planetary gears 5 and facilitates disassembly and assembly. The mounting shaft 10 is fixedly connected to the upper surface of the mounting disc 8 and is located radially inside the mounting ring 9. The mounting shaft 10 is connected to the mounting ring 9 via a second connecting plate 12. The upper part of the mounting ring 9 has multiple radially arranged second expansion through holes 13.

The second expansion through holes 13 provide additional support for the expansion tool 3. The second expansion through holes 13 and the first expansion through holes 2-1 cooperate to enhance the stability of the expansion tool 3 and ensure the dynamic concentricity and force transmission stability of the expansion tool 3 during the flaring process.

[0024] As a preferred embodiment of this example, specifically, such as Figure 2 As shown, the axial cross-section of the expanding tool 3 is L-shaped. The expanding tool 3 includes a first expanding plate 3-2 and a second expanding plate 3-3 connected to each other, which can increase the stability of the expanding tool 3 during sliding, prevent the expanding nozzle 4 at the end of the expanding tool 3 from shaking during the expanding process, and improve the expanding accuracy. The first gear part 3-1 is set on the surface of the first expanding plate 3-2 away from the second expanding plate 3-3. A protrusion 14 is provided at the connection between the expanding tool 3 and the expanding nozzle 4. The protrusion 14 restricts the running position of the expanding tool 3, prevents the expanding tool 3 from retracting excessively when retracting, and avoids damage to the expanding nozzle 4. The expanding nozzle 4 is wedge-shaped. The expanding nozzle 4 uses its inclined structure to convert the radial expansion force into a uniform spreading force on the inner wall of the aluminum alloy tube, performing the expanding inspection action of the fusion joint, which is conducive to quickly expanding the fusion joint of the aluminum alloy tube and improving the expanding speed. The expanding head 4 is detachably fixed to the front end of the expanding tool 3, which facilitates the replacement of different specifications of mold heads according to actual needs, improving the flexibility and adaptability of the device. At the same time, this design also facilitates the maintenance and replacement of the expanding head 4, reducing the maintenance cost of the device.

[0025] In a preferred embodiment, specifically, the expansion joint 4 is equipped with a sensor for collecting test parameters. The main structure 1 is equipped with a controller 15, which is connected to both the sensor and the motor 7. The controller 15 is used to control the rotation direction and speed of the motor shaft 7-1 of the motor 7, and also to collect test parameters to achieve intelligent inspection. The controller 15 is electrically connected to the motor 7 and to the sensor.

[0026] The use of the flaring inspection device for ultra-large diameter aluminum alloy pipe fusion joints according to this utility model includes the following steps: Step 1, Sample clamping: Place the aluminum alloy tube sample on the workbench, ensuring that its axis is coaxial with the fixing ring 2, and align the fusion joint with the flared head 4.

[0027] Step 2, the transmission gear 6 rotates: the controller 15 drives the motor shaft 7-1 of the motor 7 to rotate, the motor shaft 7-1 drives the transmission disk to rotate, the transmission disk drives the transmission gear 6 to rotate, and then meshes with the planetary gear 5, the planetary gear 5 transmits the rotational motion to the expansion fixture 3.

[0028] Step 3, Radial Flaring: The flaring tool 3 slides linearly along the first flaring tool through hole 2-1 and the second flaring tool through hole 13, pushing the flaring head 4 to evenly open the fusion joint of the aluminum alloy tube sample.

[0029] Step 4, Data Analysis: Monitor stress and deformation during the flaring process in real time, and evaluate the welding quality and fracture morphology of the fusion joint.

[0030] Step 5, Reset and Remove Sample: The controller 15 drives the motor shaft 7-1 of the motor 7 in the opposite direction, the expander 3 is reset, and the aluminum alloy tube sample is removed to complete the inspection.
