Description

Technical Field

[0001] The present invention relates to the technical field of weld detection, and in particular to a device and method for detecting welds of oil inlet and outlet ports of a deep-sea flat actuator made of TC4 material. Background Art

[0002] The flat actuator test piece is the core component of the DEST simulator project of the Wuhan Institute of Rock and Soil Mechanics, Chinese Academy of Sciences. Its role is to reproduce the real stress environment through experimental simulation and provide a process design basis for the evaluation and exploitation of "combustible ice". The so-called "combustible ice" is an ice-like crystalline substance composed of natural gas and water. It is a new energy source with great development potential hidden in seabed sediments and frozen soil. The TC4 flat actuator is a large-tonnage small flat flexible loading device, which is assembled and welded by a long U-shaped end, a short U-shaped end, a panel, an inlet and outlet pipe and a grid component. It is mainly formed by a combination of vacuum electron beam, laser welding and manual argon arc welding. In order to accurately simulate the stress environment, the product has extremely high shape and position tolerance requirements without damaging the surface of the raw materials. The inlet and outlet pipes are usually fixed to the outside of the long U shape by welding. After the welding is completed, the welding of the inlet and outlet pipes needs to be inspected to ensure its stability after being put into use.

[0003] Publication No. CN220473404U discloses a circular weld detection device, and the problems raised in its background technology are: circular welds are mostly inspected by manual visual sampling, with poor accuracy; and because the weld is circular, the inspector needs to rotate the entire workpiece for inspection, which is inconvenient to operate and inefficient. It uses a first supporting mechanism to support the second end of the circular workpiece, and the rotating mechanism is constructed to drive the circular workpiece to rotate at least 360°, so that the weld detector can continuously and completely detect the circular weld, and the detection process has a high degree of automation.

[0004] Based on the existing technology, there are the following problems: When inspecting an annular workpiece, it is usually rotated and then inspected by an infrared ranging sensor. However, the annular workpiece is smaller in size and lighter in weight than the infrared ranging sensor. In the actual rotation process, the rotating workpiece is less accurate than the rotating infrared ranging sensor and is prone to offset, which affects the accuracy of the detection. In addition, the infrared ranging sensor is prone to loose installation due to long-term operation during actual use, and the existing installation mechanism is not convenient for monitoring the loose infrared ranging sensor, which affects the stability and accuracy of the detection. In order to solve the above problems, a deep-sea flat actuator oil inlet and outlet weld detection device and method using TC4 material are proposed. Summary of the invention

A rotating assembly 33 is arranged on the top of the mounting seat 31. A detection assembly 32 is symmetrically arranged on the inner side of the rotating assembly 33. The detection assembly 32 includes: The first connecting seat 323 is arranged on the inner side of the rotating component 33, and the second connecting seat 324 is fixedly provided on the side of the first connecting seat 323 away from the rotating component 33, and the mounting cover 326 is fixedly provided on the side of the second connecting seat 324 away from the first connecting seat 323, and the first infrared ranging sensor 325 is disassembled and installed inside the mounting cover 326, and the first auxiliary component 321 and the second auxiliary component 322 are respectively arranged inside the first connecting seat 323 and the second connecting seat 324 to determine whether the position of the first infrared ranging sensor 325 is offset.

[0025] See also Fig.14 , the fixing mechanism 2 comprises: The fixed seat 22 is fixedly arranged on the top of the detection platform 1. A fixed plate 23 for clamping the flat actuator 5 is movably arranged on the top of the fixed seat 22. Two fixed plates 23 are provided and are symmetrically arranged with respect to the center point of the fixed seat 22. The side wall of the fixed seat 22 is provided with a third driving component 21 for driving the two fixed plates 23 to move closer to or away from each other, so that after the fixed plates 23 clamp and fix the flat actuator 5, the inlet and outlet oil pipes 51 of the flat actuator 5 are located in the middle position between the two detection mechanisms 3.

[0026] The third driving assembly 21 includes a third slide groove opened on the top of the fixed seat 22, and a third slider symmetrically arranged with the center point of the fixed seat 22 is placed inside the third slide groove, and the top of the third slider is fixedly connected to the top of the fixed plate 23. The side wall of the fixed seat 22 is rotatably provided with a third threaded rod extending into the third slide groove, and the third threaded rod is threadedly connected to the third slider. The third threaded rod is a bidirectional screw. A third servo motor is fixedly provided on the side wall of the fixed seat 22, and the output shaft of the third servo motor is fixedly connected to the end of the third threaded rod through a coupling, thereby driving the third slider to approach or move away from each other, so as to drive the fixed plate 23 to approach or move away from each other, thereby clamping and fixing the flat actuator 5.

[0027] In a specific implementation, the third driving assembly 21 drives the fixing plates 23 to approach each other to clamp and fix the flat actuator 5, so that the fixing plates 23 are brought close to each other to clamp and fix the flat actuator 5, so that the inlet and outlet oil pipes 51 of the flat actuator 5 are located in the middle position between the two detection assemblies 32, so that the detection assembly 32 can detect the welds of the inlet and outlet oil pipes 51. By fixing the flat actuator 5 and making the first infrared distance measuring sensor 325 rotate in a circle, the flatness and expansion joint of the weld of the inlet and outlet oil pipes 51 are detected by rotating the first infrared distance measuring sensor 325 when the flat actuator 5 is fixed. Compared with the infrared distance measuring sensor, the flat actuator 5 is larger in size and heavier in weight. The flat actuator 5 is rotated in a circle for detection, so as to cause the flat actuator 5 to deviate, thereby fixing the flat actuator 5 and making the detection component 32 rotate to improve the detection accuracy. In addition, during the detection process, the flat actuator 5 is fixed to facilitate other detections of the flat actuator 5 during the detection process, such as helium leak detection. Specifically, when performing helium leak detection, the oil inlet or outlet pipe for flatness and expansion detection is blocked. When blocking, the inner wall of the oil inlet or outlet pipe is blocked to avoid affecting the subsequent flatness and expansion detection. Then, helium is transported from another oil inlet or outlet pipe to the flat actuator 5 to detect the helium leakage. When the first infrared ranging sensor 325 of the detection component 32 makes a circular rotation, the distance information monitored by the first infrared ranging sensor 325 is used to determine the flatness of the weld of the inlet and outlet pipes 51. The difference between the distance to the end of the inlet and outlet pipes 51 and the distance to the flat actuator 5 is measured by the first infrared ranging sensor 325 and compared with the length of the inlet and outlet pipes 51 themselves to determine the expansion and contraction amount of the inlet and outlet pipes 51 before and after being welded to the flat actuator 5.

[0035] Example 2: Please refer to Figure 8 , Fig. 9 and Fig.10 The technical solution of this embodiment is different from that of the first embodiment in that the second auxiliary component 322 includes: The first cavity 3228 is opened in the second connecting seat 324 . The inner wall of the first cavity 3228 is sleeved with a first piston block 3229 . The side wall of the first piston block 3229 is fixed with a first stop rod 3221 extending into the mounting cover 326 .

[0036] The second auxiliary component 322 also includes: The second cavity 3227 is provided in the second connecting seat 324 and is connected with the first cavity 3228. A movable groove 3220 is provided on the top of the second connecting seat 324. A second piston block 3225 is sleeved on the inner wall of the second cavity 3227. A second push rod 3222 extending into the movable groove 3220 is fixedly provided on the side wall of the second piston block 3225. The first cavity 3228 and the second cavity 3227 are both filled with pressurized gas. The gas pressure in the second cavity 3227 and on the side of the second piston block 3225 close to the second push rod 3222 is greater than the gas pressure on the side of the second piston block 3225 away from the second push rod 3222. The side walls of the first piston block 3229 and the second piston block 3225 are sealed with the inner walls of the first cavity 3228 and the second cavity 3227, respectively. The touch panel 3223 is fixed on the side wall of one end of the second support rod 3222 located in the movable groove 3220, and extends to the top of the second connecting seat 324. The side wall of the touch panel 3223 fits with the inner wall of the movable groove 3220 to limit the touch panel 3223. A control button 328 is movably provided on the top of the second connecting seat 324 to give an early warning by squeezing the control button 328 through the touch panel 3223. A movable component 327 for adjusting the position of the control button 328 is provided on the top of the second connecting seat 324.

[0037] In a specific implementation, due to the detachable design of the first infrared ranging sensor 325, when the first infrared ranging sensor 325 is installed in the mounting cover 326 by means of bolts, the first infrared ranging sensor 325 squeezes the first push rod 3221, and the first push rod 3221 drives the first piston block 3229 to squeeze the gas in the first cavity 3228 to move, so that the gas in the first cavity 3228 is transferred to the second cavity 3227, and squeezes the second piston block 3225 and the second push rod 3222 to move, so as to drive the touch panel 3223 away from the control button 328. When the distance sensor 325 is loose, the squeezing force on the first push rod 3221 is reduced. At this time, the gas in the second cavity 3227 and located on the side of the second piston block 3225 close to the second push rod 3222 squeezes the second piston block 3225, so that the gas in the first cavity 3228 squeezes the first piston block 3229 and the first push rod 3221. At the same time, the second push rod 3222 drives the touch panel 3223 to approach the control button 328, thereby issuing an early warning to remind the staff that the installation of the first infrared distance sensor 325 is loose, that is, to avoid affecting the accuracy of the detection. By setting the pressure gas, when the release position of the first infrared ranging sensor 325 is loose, the loose information of the first infrared ranging sensor 325 can be sensitively captured to avoid affecting the accuracy of detection.

[0038] The connection point between the first cavity 3228 and the second cavity 3227 is located on the inner wall of the first cavity 3228 away from the first stop rod 3221; The inner walls of the first cavity 3228 and the second cavity 3227 are both fixedly sleeved with a limiting ring 3226 to limit the positions of the first piston block 3229 and the second piston block 3225 respectively. By setting the limiting ring 3226 to limit the positions of the first piston block 3229 and the second piston block 3225, it is prevented that the first piston block 3229 drives the first stop rod 3221 to move completely into the first cavity 3228, and the second piston block 3225 is prevented from moving to the connection between the first cavity 3228 and the second cavity 3227, so as to avoid affecting the use; The inner wall of the mounting cover 326 is provided with a first through hole connected to the first cavity 3228 for allowing the first push rod 3221 to move; the interior of the second connecting seat 324 and between the second cavity 3227 and the movable groove 3220 is provided with a second through hole for sleeve-mounting the second push rod 3222; a sealing ring 3224 is fixedly sleeved on the inner wall of the second through hole to seal the second push rod 3222 and the second through hole; the second through hole is connected to the second cavity 3227; the sealing ring 3224 is provided to seal the movement of the second push rod 3222, thereby ensuring the sealing performance and facilitating the second push rod 3222 to drive the touch plate 3223 to move; the first piston block 3229 and the second piston block 3225 are dynamically sealed with the inner wall of the first cavity 3228 and the inner wall of the second cavity 3227 respectively for practical use.

[0040] During the specific implementation, the second threaded rod 3271 is rotated, and the second threaded rod 3271 drives the second slider to move along the second slide groove during the rotation, thereby driving the connecting piece to move, and then driving the control button 328 to move, so as to adjust the distance between the control button 328 and the touch panel 3223, thereby adjusting the sensitivity of the warning, which is convenient for adjustment according to the actual detection situation.

[0041] See also Fig.12 and Fig.13 , the first auxiliary component 321 includes: The identification block 3211 is fixedly disposed on the inner wall of the first connection seat 323 and is designed in a truncated cone shape. An adjustment component 3212 is disposed on a side of the identification block 3211 away from the second connection seat 324; The second infrared ranging sensor 3213 is fixed on the inner wall of the first connecting seat 323 and is arranged opposite to the identification block 3211. The interior of the first connecting seat 323 is hollow in design. A notch is provided at the top of the first connecting seat 323 and at the top of the second infrared ranging sensor 3213, and a cover is fixed at the notch by bolts. By opening the cover, the adjustment component 3212 can be easily operated.

[0042] The adjustment component 3212 includes: The guide rod 3214 is sleeved on the side of the identification block 3211 close to the second infrared ranging sensor 3213, and the side of the guide rod 3214 away from the identification block 3211 is fixed with an identification plate 3215, a jack is provided on the side wall of the guide rod 3214, and a guide hole matching the guide rod 3214 is provided on the side of the identification block 3211 close to the second infrared ranging sensor 3213, and a placement groove is provided on the inner wall of the guide hole; The plug rod 3217 is sleeved on the inner wall of the placement groove, and one end extends into the guide hole, and the other end extends to the outside of the identification block 3211. The plug rod 3217 is adapted to the insertion hole. The side wall of the plug rod 3217 is fixedly sleeved with a first ring body 3218, and the outer wall of the first ring body 3218 is sleeved in the placement groove. The inner wall of the placement groove is fixedly sleeved with a second ring body 3219, and the inner wall of the second ring body 3219 is sleeved on the side wall of the plug rod 3217. A spring is sleeved on the side wall of the plug rod 3217 and between the first ring body 3218 and the second ring body 3219.

[0043] In a specific implementation, when the second connection base 324 and the mounting cover 326 are loosened as a whole, the first infrared ranging sensor 325 is loosened at this time, and the end of the identification block 3211, that is, the side close to the second infrared ranging sensor 3213, will deviate. Since the identification block 3211 is designed in a truncated cone shape, the distance information monitored by the second infrared ranging sensor 3213 changes, so as to detect the stability of the overall installation of the second connection base 324 and the mounting cover 326, so as to avoid affecting the accuracy of the detection. By inserting the guide rod 3214 into the guide hole, the insertion rod 3217 is inserted into the insertion hole, so that the identification plate 3215 can be easily replaced. By replacing identification plates 3215 of different areas, the sensitivity of the second infrared ranging sensor 3213 can be adjusted, so as to facilitate actual use; By setting the card slot 3216 and the card plate, the guide rod 3214 and the card plate are inserted into the guide hole along the card slot 3216 so that the socket faces the plug rod 3217, which facilitates the plug rod 3217 to be inserted into the socket under the action of the spring, thereby facilitating the fixation of the identification plate 3215. When replacing, pull the plug rod 3217 to extend to one end outside the identification block 3211, so that the plug rod 3217 is separated from the socket, and then the identification plate 3215 can be replaced.
