Description

Technical Field

[0001] This utility model relates to the field of submerged arc welding technology, and specifically to a welding wire position detection and calibration device for submerged arc welding. Background Technology

[0002] Submerged arc welding is widely used in industrial production for welding steel structures, pipelines, and large machinery. Its welding quality directly affects structural safety and service life. In traditional welding processes, the accuracy of the welding wire position is crucial for weld quality. However, existing welding equipment typically relies on manual labor or a single sensor for position detection, resulting in insufficient detection accuracy, numerous blind spots, and significant data deviations. Especially in complex configurations or when affected by weld surface reflections, single-point detection can easily lead to welding wire misalignment or weld center deviations that are difficult to detect, thus increasing rework rates and the risk of welding defects. Furthermore, existing equipment relies heavily on manual operation when adjusting the welding head position, lacking automated calibration functions and failing to achieve precise bidirectional displacement adjustment during welding, impacting production efficiency and welding stability.

[0003] In view of the above, this application proposes a welding wire position detection and calibration device for submerged arc welding to solve the above problems. The device should be able to achieve precise displacement in both vertical and horizontal directions. At the same time, it should combine multi-sensor collaborative detection technology to overcome the blind zone and posture deviation problems of single sensors, realize automatic calibration of welding head and stable control of welding trajectory, thereby improving welding accuracy, production efficiency and device maintenance convenience.

They are only for the convenience of describing the technical solution of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] This application proposes a welding wire position detection and calibration device for submerged arc welding, the details of which are as follows:

[0039] For reference Figure 1-4 This application primarily utilizes the cooperation of a first sensor 701, a second sensor 801, a vertical linear slide rail 1, and a horizontal linear slide rail 2 to achieve position detection and calibration. When used in conjunction with existing devices, this structure does not affect the execution of their original motion steps and is easy to disassemble, thereby improving the convenience of subsequent maintenance and repair.

[0040] For reference Figure 1-4 The vertical linear slide rail 1 is installed on a supportable crossbeam, and the horizontal linear slide rail 2 is set on the vertical linear slide rail 1 and can move vertically in a straight line along the vertical linear slide rail 1; the connecting shaft 3 is installed on the slider of the horizontal linear slide rail 2 and can move horizontally in a straight line along the horizontal linear slide rail 2.

[0041] With the cooperation of the above structures, the connecting shaft 3 can perform precise linear displacement in both the vertical and horizontal directions, thereby realizing bidirectional adjustment of the welding head in both directions. Simultaneously, two sensors are installed to detect and calibrate the displacement process in real time, ensuring accurate alignment of the welding head and improving the precision and stability of welding positioning.

[0042] For reference Figure 1-4 A mounting plate 31 is provided on one side of the connecting shaft 3. The mounting plate 31 is used to connect and install with an external welding head assembly. The welding head assembly includes a welding torch and a welding material tank structure. The welding torch and the welding material tank are integrated into one assembly and then installed on the mounting plate 31 for operation.

[0043] For reference Figure 1-4 After the welding head assembly is installed on the mounting plate 31, the structure is positioned on one side of the connecting shaft 3. At this time, the bottom of the connecting shaft 3 is empty, and the cylindrical shaft 4, extension shaft 5, rotating part 6, adjusting part 7 and bending shaft 8 are set in this empty area for cooperative operation.

[0044] For reference Figure 1-4 The cylindrical shaft 4 is detachably mounted at the bottom of the connecting shaft 3 by bolts. When not in use or for maintenance, this structure can be removed for comprehensive maintenance of its structure and the parts mounted on it.

[0045] The extension shaft 5 is threaded to the bottom of the cylindrical shaft 4, and the threaded connection facilitates its daily disassembly and assembly.

[0046] For reference Figure 1-4 The rotating component 6 is rotatably mounted at the bottom of the cylindrical shaft 4, and includes a cylindrical shaft 61, a connecting rod 62, and a moving rod 63. The cylindrical shaft 61 is rotatably sleeved on the outer side of the bottom of the cylindrical shaft 4, the connecting rod 62 is fixedly connected to one side of the cylindrical shaft 61, and the moving rod 63 is rotatably connected to the end of the connecting rod 62 away from the cylindrical shaft 61. The surface of the moving rod 63 is provided with a straight groove 64 for mounting an adjusting component 7. The adjusting component 7 can slide and adjust within the straight groove 64, and a first sensor 701 is mounted at its bottom.

[0047] By rotating the circular shaft 61, the connecting rod 62 and the moving rod 63 can be rotated synchronously, thereby realizing the angle adjustment of the first sensor 701; at the same time, the connecting rod 62 and the moving rod 63 can also be rotated; furthermore, with the help of the linear groove 64, the position of the adjusting component 7 can be finely linearly adjusted, so that the first sensor 701 can fit more closely to the part to be detected, improving the accuracy and flexibility of detection.

[0048] Furthermore, the adjusting component 7 includes a threaded shaft 71, a locking shaft 72, a round rod 73, and a first rotating disk 74.

[0049] The bottom of the threaded shaft 71 is movably engaged in the straight groove 64, enabling reciprocating linear motion along the direction of the straight groove 64. The locking shaft 72 is threadedly connected to the threaded shaft 71, and precise fine-tuning of the position of the threaded shaft 71 can be achieved through rotational engagement. The round rod 73 is fixedly installed at the bottom of the threaded shaft 71 to provide stable support for the lower structure. The first rotating disk 74 is rotatably installed at the bottom of the round rod 73, and a first sensor 701 is provided at its bottom. The upper end of the first sensor 701 is connected to the bottom surface of the first rotating disk 74 through a rotating shaft, thereby collecting data from the corresponding image after rotational positioning.

[0050] Its first sensor 701 is used to detect the condition of the welding wire, transmit the collected data to an external processing control system for processing, and control the vertical linear slide rail 1 and the horizontal linear slide rail 2 to adjust the position of the welding gun after data processing.

[0051] Considering that a single sensor may cause data deviations during the detection process due to factors such as welding angle, reflection interference, or surface obstruction, and may even cause misjudgments due to detection blind spots in certain postures, this application further provides a bending shaft 8 and a second sensor 801 in the device.

[0052] The bending shaft 8 is located at the bottom of the extension shaft 5, and the second sensor 801 is mounted at its bottom end. Specifically, the bending shaft 8 consists of a flexible metal hose 81 and a second rotating disk 82. One end of the flexible metal hose 81 is fixedly connected to the bottom of the extension shaft 5 to achieve flexible bending and posture transition, allowing the lower sensor to self-adjust its angle according to the weld position. The second rotating disk 82 is rotatably mounted at the bottom end of the flexible metal hose 81 for angle adjustment and posture self-adaptation. The second sensor 801 is movably mounted at the lower end of the second rotating disk 82 via a rotating shaft, and its detection surface can accurately correspond to the submerged arc welding position after rotational adjustment.

[0053] During operation, the second sensor 801 and the first sensor 701 form a collaborative detection structure. When the welding wire is detected to be deviated, the weld center is deviated, or the angle is abnormal, the system can issue a prompt signal in real time and automatically calibrate by controlling the vertical linear slide rail 1 and the horizontal linear slide rail 2 to restore the welding head to the correct position and ensure the stability and accuracy of the welding trajectory.

[0054] It should be noted that the aforementioned sensors are common existing vision sensors, and their coordination with the control system is also a common existing technical approach, which will not be elaborated upon further in this application.

[0055] In this invention, the working steps of the device are as follows:

[0056] 1. First, the vertical linear slide rail 1 is fixedly installed on the supportable crossbeam, and the horizontal linear slide rail 2 is installed at the slider of the vertical linear slide rail 1, so that it can achieve precise up and down linear movement in the vertical direction; then, the connecting shaft 3 is connected to the slider to ensure that the connecting shaft 3 can move horizontally along the horizontal linear slide rail 2, thereby forming a bidirectional adjustable structure of the welding head.

[0057] 2. Next, the welding head assembly (including the welding torch and the welding material tank) is installed on the mounting plate 31 and fixedly connected to the connecting shaft 3 through the mounting plate 31, so that the welding head can be adjusted in the vertical and horizontal directions with the connecting shaft 3; at this time, the cylindrical shaft 4, extension shaft 5, rotating part 6, adjusting part 7 and bending shaft 8 provided at the bottom of the connecting shaft 3 enter the working state, and the first sensor 701 and the second sensor 801 are respectively in the detection preparation state;

[0058] 3. Then, after the equipment is started, the first sensor 701 monitors the welding wire position in real time and transmits the collected data to the external processing and control system. When a slight offset or change in attitude angle is detected in the welding wire position, the system automatically controls the vertical linear slide rail 1 and the horizontal linear slide rail 2 to make precise adjustments based on the sensor feedback data, realizing automatic fine-tuning and dynamic following of the welding torch position. If an angle deviation, obstruction, or blind spot occurs during the detection process, the second sensor 801 compensates for the angle through the flexible structure of the bending shaft 8, and its detection surface automatically adjusts to the optimal posture, forming a collaborative detection with the first sensor 701 to ensure the integrity and reliability of the detection information.

[0059] 4. Finally, when the control system determines that the welding wire position has returned to the set trajectory, the device automatically completes the position calibration operation, and the welding head returns to normal working condition. The entire process realizes real-time monitoring of the welding wire position, automatic offset identification, and self-calibration closed-loop control, effectively improving welding accuracy and weld consistency, while also possessing good assembly compatibility and maintenance convenience.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
