Description

Technical Field

[0001] This utility model relates to the field of duplex stainless steel welding technology, and in particular to a duplex stainless steel online welding bead tracking system. Background Technology

[0002] Duplex stainless steel (DSS) refers to stainless steel in which ferrite and austenite each account for approximately 50%, with the lesser phase typically comprising at least 30%. This type of steel combines the characteristics of both austenitic and ferritic stainless steels. Compared to ferritic stainless steel, it exhibits higher plasticity and toughness, no room temperature brittleness, and significantly improved resistance to intergranular corrosion and weldability. Simultaneously, it retains the 475℃ brittleness and high thermal conductivity of ferritic stainless steel, and possesses superplasticity. Compared to austenitic stainless steel, it has higher strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel also exhibits excellent pitting corrosion resistance and is a nickel-saving type of stainless steel.

[0003] A search revealed a patent document with publication number "CN213497084U" that discloses an automatic tracking and correction system for argon arc welding seams. This system includes a control box, a control mainboard housed within the control box, a touchscreen display on the surface of the control box, a fixed guide rail fixed to a welding base, a vertical guide rail vertically movably connected to the fixed guide rail, a welding torch correction assembly mounted on a horizontal guide rail and connected to the control mainboard, and a camera torch assembly fixed to the welding torch correction assembly and connected to the control mainboard. The camera in the camera torch assembly enables video monitoring during steel pipe welding, and combined with existing video recognition technology, it tracks the weld seam. The control assembly uses the welding torch correction assembly to adjust the position of the welding torch, thereby achieving welding of the seam and ensuring welding quality.

[0004] The aforementioned automatic tracking and correction system for argon arc welding seams can also be applied to online welding seam tracking in duplex stainless steel.

[0005] Based on the above search and combined with existing technology, it was found that in existing online welding weld bead tracking systems, the camera gun is prone to shaking at its end during movement, at the start and the moment of stopping, because its end is suspended and unsupported. This results in momentary (corresponding to the moment of start and stop of movement) or continuous (corresponding to the movement process) image blurring, affecting the recognition and tracking effect. Therefore, a duplex stainless steel online welding weld bead tracking system is needed. Utility Model Content

[0006] The purpose of this application is to provide a weld bead tracking system for online welding of duplex stainless steel to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this application provides the following technical solution: a duplex stainless steel online welding bead tracking system, including a fixed guide rail, a vertical guide rail, a horizontal guide rail, a welding torch correction assembly, and a camera torch assembly. The camera torch assembly includes a support column, a connecting block fixed to one end of the support column by bolts, and a column fixed to the connecting block by bolts and passing through the connecting block. The column and the support column are perpendicular to each other. An installation block is fixed to the lower end of the column, and a camera torch is rotatably mounted on one side of the installation block via an installation disc.

[0008] A support plate is fixed to the side of the mounting block near the camera gun, and an annular groove coaxial with the mounting plate is opened on the side of the support plate near the camera gun.

[0009] A support frame is slidably installed inside the annular groove. The support frame is sleeved on the end of the camera gun away from the mounting plate, and the support frame also provides a damping buffer function.

[0010] Preferably, the support frame includes:

[0011] The support frame has one end slidably connected to the annular groove via a sliding column, and the support frame is movably sleeved on the outside of the camera gun.

[0012] The movable frame is fixedly fitted onto the end of the camera gun furthest from the mounting plate, and the movable frame is located inside the support frame;

[0013] The springs are arranged in multiples and are evenly distributed in a ring along the gap between the support frame and the movable frame. The inner side of the support frame is elastically connected to the movable frame through the multiple springs.

[0014] Preferably, a sliding groove is provided on the inner side of the support frame, and a support block is slidably connected in the sliding groove. Multiple support blocks are provided and each corresponds to a multiple spring. One side of each of the multiple support blocks is fixed to one end of a multiple spring.

[0015] Preferably, an elastic block is also fixed inside the groove. Multiple elastic blocks are provided, and the multiple elastic blocks are respectively located between two adjacent support blocks. The two ends of the elastic blocks are respectively fixed to one side of two adjacent support blocks.

[0016] Preferably, the mounting block has a mounting cavity, and an electric drive structure is installed in the mounting cavity;

[0017] A rotating shaft is fixed on the side of the mounting plate away from the camera gun. The end of the rotating shaft away from the mounting plate rotates through the mounting block and extends into the mounting cavity. The end of the rotating shaft away from the mounting block is connected to the power output end of the electric drive structure.

[0018] Preferably, the electric drive structure includes a micro motor and a reduction gear set. The micro motor is fixed to the inner sidewall of the mounting cavity, the output shaft of the micro motor is connected to the input end of the reduction gear set, and the output end of the reduction gear set is connected to the end of the rotating shaft.

[0019] In summary, the technical effects and advantages of this utility model are as follows:

[0020] 1. In this utility model, by setting up a support plate and a support frame, when the camera gun moves with the mounting block, the end of the camera gun away from the mounting plate is always supported before, during, and after the movement due to the supporting effect of the support frame. This ensures that the end of the camera gun remains stable, improves the image acquisition quality, and avoids image blurring. In addition, the damping buffer provided by the support frame can also provide damping buffer support for the end of the camera gun, further protecting the end of the camera gun and preventing it from repeatedly shaking for a long time due to the vibration of the equipment itself. This further ensures the stability of the end of the camera gun, which also helps to improve the image acquisition quality. This ensures the recognition and tracking effect of the duplex stainless steel online welding weld bead tracking system, and ultimately ensures the stability of the welding quality.

[0021] 2. In this utility model, by setting the support block, the end of the spring near the support frame can slide in the groove with the support block, so that the spring can cope with lateral displacement and provide a more comprehensive damping support effect. Moreover, after the end of the spring has a space for movement, it can cope with a larger amplitude of vibration force, thereby further improving the elastic support effect of the support frame on the camera gun, making the end of the camera gun more stable when in use.

[0022] 3. In this utility model, by starting the micro motor, the micro motor drives the rotating shaft to rotate through the reduction gear set, thereby causing the mounting plate to drive the camera gun to rotate, thus achieving the effect of automatically adjusting the angle of the camera gun. Compared with the prior art, which requires manual adjustment, the adjustment is more convenient and faster, without the need to stop the machine for adjustment, and can be used in combination with the control components of the existing duplex stainless steel online welding weld track system, thus improving the basic structure.

[0023] In addition, using a reduction gear set for transmission can make the rotation accuracy of the mounting plate higher, thereby making the angle error before and after the camera gun is adjusted smaller and the adjustment effect better. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example: Reference Figures 1-4 The online welding bead tracking system for duplex stainless steel shown includes a fixed guide rail, a vertical guide rail, a horizontal guide rail, a welding torch correction assembly, and a camera torch assembly.

[0032] The camera gun assembly includes a support column 1, a connecting block 2 fixed to one end of the support column 1 by bolts, and a column 3 fixed to the connecting block 2 by bolts and passing through the connecting block 2. The column 3 is perpendicular to the support column 1. A mounting block 4 is fixed to the lower end of the column 3. A camera gun 5 is rotatably mounted on one side of the mounting block 4 via a mounting plate 41.

[0033] The structure and working principle of the fixed guide rail, vertical guide rail, horizontal guide rail, welding gun straightening assembly and camera gun 5 are all existing technologies (disclosed in the patent document with publication number "CN213497084U"), which are well known to those skilled in the art, and will not be described in detail here.

[0034] A support plate 6 is fixed on the side of the mounting block 4 near the camera gun 5. The side of the support plate 6 near the camera gun 5 has an annular groove 61 that is coaxial with the mounting plate 41.

[0035] A support frame 7 is slidably installed in the annular groove 61. The support frame 7 is sleeved on the end of the camera gun 5 away from the mounting plate 41, and the support frame 7 also provides a damping buffer function.

[0036] Based on the above structure, when the camera gun 5 moves with the mounting block 4, the end of the camera gun 5 away from the mounting plate 41 is always supported before and after movement and during movement due to the support of the support frame 7. This keeps the end of the camera gun 5 stable, improves its image acquisition quality, and avoids image blurring. In addition, the damping buffer provided by the support frame 7 can also dampen and buffer the end of the camera gun 5, further protecting the end of the camera gun 5 and preventing it from repeatedly shaking for a long time due to the vibration of the equipment itself. This further ensures the stability of the end of the camera gun 5, which is also conducive to improving image acquisition quality. This ensures the recognition and tracking effect of the duplex stainless steel online welding weld bead tracking system, and ultimately ensures the stability of the welding quality.

[0037] In addition, the support frame 7 can slide along the annular groove 61 as the angle of the camera gun 5 is adjusted, thereby ensuring that the support frame 7 can always provide stable support for the camera gun 5 after the camera gun 5 is adjusted to any angle, thus meeting the usage requirements of the camera gun 5.

[0038] Furthermore, the support frame 7 includes a support frame 71, a movable frame 72, and a spring 73. One end of the support frame 71 is slidably connected to the annular groove 61 via a sliding post 76, and the support frame 71 is movably sleeved on the outside of the camera gun 5.

[0039] The movable frame 72 is fixedly sleeved on the end of the camera gun 5 away from the mounting plate 41, and the movable frame 72 is located inside the support frame 71;

[0040] Multiple springs 73 are provided, and the multiple springs 73 are evenly distributed in a ring along the gap between the support frame 71 and the movable frame 72. The inner side of the support frame 71 is elastically connected to the movable frame 72 through the multiple springs 73.

[0041] By using the support frame 71, the movable frame 72, and the spring 73, the support frame 71, the movable frame 72, and the spring 73 work together to provide elastic support to the end of the camera gun 5 that is away from the mounting plate 41 during the use of the duplex stainless steel online welding weld bead tracking system. This ensures that the end of the camera gun 5 remains stable. When the end of the camera gun 5 tends to shake due to movement, the support frame 71, the movable frame 72, and the spring 73 work together to interfere with the end of the camera gun 5, thereby quickly eliminating the shaking tendency and avoiding image blurring, thus improving the image acquisition quality of the camera gun 5.

[0042] Furthermore, a sliding groove 711 is provided on the inner side of the support frame 71, and a support block 74 is slidably connected in the sliding groove 711. Multiple support blocks 74 are provided and correspond one-to-one with multiple springs 73. One side of each of the multiple support blocks 74 is fixed to one end of each of the multiple springs 73.

[0043] An elastic block 75 is also fixed inside the slide groove 711. Multiple elastic blocks 75 are provided, and the multiple elastic blocks 75 are respectively located between two adjacent support blocks 74. The two ends of the elastic block 75 are respectively fixed to one side of two adjacent support blocks 74.

[0044] By setting the support block 74, the end of the spring 73 near the support frame 71 can slide in the groove 711 with the support block 74, so that the spring 73 can cope with lateral displacement and provide a more comprehensive damping support effect. Moreover, after the end of the spring 73 has room to move, it can cope with a larger amplitude of vibration force, thereby further improving the elastic support effect of the support frame 7 on the camera gun 5, making the end of the camera gun 5 more stable during use.

[0045] Furthermore, an installation cavity 42 is provided inside the installation block 4, and an electric drive structure 8 is installed inside the installation cavity 42;

[0046] A rotating shaft 411 is fixed on the side of the mounting plate 41 away from the camera gun 5. The end of the rotating shaft 411 away from the mounting plate 41 rotates through the mounting block 4 and extends into the mounting cavity 42. The end of the rotating shaft 411 away from the mounting block 4 is connected to the power output end of the electric drive structure 8.

[0047] Specifically, the electric drive structure 8 includes a micro motor 81 and a reduction gear set 82. The micro motor 81 is fixed to the inner wall of the mounting cavity 42. The output shaft of the micro motor 81 is connected to the input end of the reduction gear set 82. The output end of the reduction gear set 82 is connected to the end of the rotating shaft 411.

[0048] By activating the micro motor 81, the micro motor 81 drives the rotating shaft 411 to rotate through the reduction gear set 82, thereby causing the mounting plate 41 to drive the camera gun 5 to rotate, thus achieving the effect of automatically adjusting the angle of the camera gun 5. Compared with the existing technology that requires manual adjustment, the adjustment is more convenient and faster, without the need to stop the machine for adjustment, and can be used in combination with the control components of the existing duplex stainless steel online welding weld track system, improving the basic structure.

[0049] In addition, using the reduction gear set 82 for transmission can make the rotation accuracy of the mounting plate 41 higher, thereby making the angle error of the camera gun 5 before and after adjustment smaller and the adjustment effect better.

[0050] It should be noted that the micro motor 81 can also be connected to an external controller via a wireless communication module, thereby enabling remote control of the micro motor 81 to start and stop, making it easier for staff to adjust and control the angle of the camera gun 5 during use. Both the controller and the wireless communication module are commonly used devices in the prior art that are suitable for this embodiment, and are designed to achieve the aforementioned control effect. Their structure and working principle are common knowledge and will not be described in detail here.

[0051] The working principle of this utility model is as follows: During daily use, when the camera gun 5 moves with the mounting block 4, the end of the camera gun 5 away from the mounting plate 41 is always supported by the support frame 7 before, during, and after the movement. This ensures that the end of the camera gun 5 remains stable, improving the image acquisition quality and preventing image blurring. In addition, the damping buffer provided by the support frame 7 also provides damping buffer support for the end of the camera gun 5, further protecting it from prolonged repeated shaking due to the vibration of the equipment itself. This further ensures the stability of the end of the camera gun 5, which also helps improve the image acquisition quality. This ensures the recognition and tracking effect of the duplex stainless steel online welding weld bead tracking system, ultimately guaranteeing the stability of the welding quality.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
