Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a double-gun side beam welding machine. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Welding equipment can be divided into various types according to the process and the shape of the weldment. Among them, the side beam welding machine is a device specifically used for welding long strip workpieces (such as: large-diameter pipes, pressure vessel cylinders, stainless steel containers, etc.).

[0003] Patent No. 202422091046.0 discloses a side beam welding machine, which includes a base and a welding head. The base is connected to a first column and a second column, both of which are arranged in a direction perpendicular to the base. A crossbeam is slidably arranged between the first column and the second column. The first column and the second column are provided with a lifting mechanism for driving the crossbeam to rise and fall.

Therefore, the above terms should not be construed as a limitation of this utility model.

[0023] Please refer to Figure 1 , Figure 2 and Figure 8As shown, this application discloses a double-gun side beam welding machine, including a worktable and a frame mechanism and a bracket mechanism 4 disposed on the worktable. The frame mechanism includes a support component 1 and a crossbeam 2 disposed on the support component 1. The support component 1 is disposed on the worktable. The bracket mechanism 4 includes a support component 5 and a rotating component 6 disposed on the support component 5. The support component 5 is used to support the workpiece, and the rotating component 6 is used to drive the workpiece to rotate around its own axis. It also includes a column mechanism and a welding mechanism. The column mechanism includes two parallel first columns 3, which are slidably connected to the crossbeam 2. The welding mechanism includes two welding components 7, which are disposed on the two first columns 3. It should be noted that the worktable of this application serves as the installation base of the entire welding machine and is not limited to a workbench or platform surface; it can also be the ground, such as a cement floor. Since the two welding components 7 of this application are respectively set on the two first columns 3, the two welding components 7 can be used to weld the two sides of the workpiece. Compared with single-gun welding, the welding efficiency of the technical solution of this application is higher. Since the bracket mechanism 4 includes a rotating component 6, the welding machine can realize continuous welding of multiple sides of the workpiece and circumferential welding without moving the welding gun 16, thereby improving the consistency of the weld and thus improving the welding quality.

[0024] Furthermore, the support assembly 1 includes two support legs 14 of the same height, which are parallel to each other and perpendicular to the workbench surface. A crossbeam 2 is located at the top of the two support legs 14 and is connected to the two support legs 14 by bolts. To enhance the stability of the connection between the support assembly 1 and the workbench surface, a base plate 15 is provided at the bottom of each support leg 14. The base plate 15 is fixedly or detachably connected to the support leg 14. The base plate 15 is provided with multiple connection holes for bolts to pass through, and one end of the bolt passes through the connection hole to connect to the workbench surface.

[0025] Please refer to the following: Figures 3-5As shown, in particular, the welding assembly 7 is connected to the first column 3 via a displacement mechanism. The displacement mechanism includes a first displacement component and a second displacement component. The second displacement component is located at the end of the first displacement component, and the first displacement component is slidably mounted on the first column 3. The welding assembly 7 is connected to the second displacement component. Specifically, the first displacement component includes a robotic arm 18, which includes an outer arm 19 and an inner arm 20 that can extend and retract relative to the outer arm 19. The inner arm 20 is connected to a drive motor or drive cylinder for driving its extension and retraction relative to the outer arm 19. The welding assembly 7 is located at the free end of the inner arm 20. A first slider 21 is provided at the end of the outer arm 19 away from the welding assembly 7. A first slide rail 22 is provided along the length of the first column 3, and the first slider 21 is slidably connected to the first slide rail 22. The telescopic robotic arm 18, formed by the outer arm 19 and the inner arm 20, along with the cooperation of the first slider 21 and the first slide rail 22, enables the welding assembly 7 to not only move vertically along the first column 3, but also to adjust the horizontal distance through the extension and retraction of the robotic arm 18, thus greatly expanding the working range of the welding assembly 7.

[0026] Furthermore, the second displacement assembly includes a longitudinal adjustment assembly 25 and a transverse adjustment assembly 26. The transverse adjustment assembly 26 is located at the free end of the inner arm 20 and is connected to the inner arm 20 via a connecting plate. The longitudinal adjustment assembly 25 is connected to the transverse adjustment assembly 26 via a first sliding assembly, allowing the longitudinal adjustment assembly 25 to slide horizontally relative to the transverse adjustment assembly 26. The welding assembly 7 is mounted on the longitudinal adjustment assembly 25. Specifically, the welding assembly 7 includes a welding torch 16 and a mounting frame 17. The welding torch 16 is detachably connected to the mounting frame 17, which is connected to the longitudinal adjustment assembly 25 via a second sliding assembly, allowing the welding torch 16 to slide vertically relative to the longitudinal adjustment assembly 25. This arrangement enables the welding torch 16 to achieve precise displacement within a small range. The second displacement assembly works in conjunction with the first displacement assembly to achieve coarse and fine adjustments to the position of the welding torch 16, thereby enabling the welding machine to adapt to the welding of more complex workpieces.

[0027] Specifically, the longitudinal adjustment assembly 25 includes a first housing and a first stepper motor. The output shaft of the first stepper motor is at least partially located within the first housing, and a second sliding assembly is connected to the output shaft of the first stepper motor. The second sliding assembly includes a rib and a first sliding member. The first sliding member is a slider and includes a first connecting portion and a second connecting portion. The first connecting portion is located within the first housing and has a through hole for the output shaft of the first stepper motor to pass through. One side of the rib is connected to the second connecting portion, and the other side of the rib is connected to the mounting bracket 17. The first sliding member, the rib, and the welding assembly 7 together reciprocate in the vertical direction following the output shaft of the first stepper motor.

[0028] The lateral adjustment assembly 26 includes a second housing and a second stepper motor. The output shaft of the second stepper motor is at least partially located within the second housing. A first sliding assembly is connected to the output shaft of the second stepper motor. Specifically, the first sliding assembly includes a second slider, which is a block slider and includes a third connecting portion and a fourth connecting portion. The third connecting portion is located within the second housing and has a through hole for the output shaft of the second stepper motor to pass through. The fourth connecting portion is connected to the first housing. The second slider, the longitudinal adjustment assembly 25, and the welding assembly 7 together reciprocate in the horizontal direction following the output shaft of the second stepper motor.

[0029] like Figure 6 and Figure 7 As shown, it can be understood that a second slide rail 24 is provided along the length of the crossbeam 2, and a second slider 23 is provided on the first column 3. The second slider 23 is slidably connected to the second slide rail 24, thereby allowing the first column 3 to slide along the axial direction of the crossbeam 2. The second slider 23 is connected to a motor to drive the second slider 23 to slide along the second slide rail 24. This arrangement allows the two first columns 3 to move independently along the crossbeam 2, thereby flexibly adjusting the distance between the two welding torches 16 according to the size of different workpieces, improving the flexibility and versatility of the welding machine.

[0030] It should be noted that the dual-gun side beam welding machine of this application also includes a controller and a voltage adaptive mechanism. The voltage adaptive mechanism can collect the arc voltage value between the welding torch 16 and the workpiece in real time and convert the arc voltage value into a corresponding arc voltage signal and send it to the controller. The voltage adaptive mechanism and the displacement mechanism are electrically connected to the controller. The controller can receive the arc voltage signal from the voltage adaptive mechanism and control the displacement mechanism to drive the welding assembly 7 to move based on the arc voltage signal, thereby realizing the adaptive adjustment of the distance between the welding torch 16 and the welding workpiece. In this way, the stability and consistency of the weld formation during the welding process can be effectively guaranteed, thereby improving the welding quality.

[0031] Please refer to Figure 8 and Figure 9 As shown, in one embodiment of this disclosure, the support assembly 5 includes a base 8 and two support frames 9. The base 8 is used to connect to the worktable surface, and the two support frames 9 are arranged parallel to each other on the base 8. The rotating assembly 6 is disposed on the support frames 9. Specifically, the rotating assembly 6 includes two oppositely arranged roller assemblies. The roller assembly includes a support frame 10 and a first roller 11 rotatably connected to the support frame 10. The support frame 10 is disposed on the support frame 9, and the first roller 11 is connected to a drive motor for driving it to rotate around its own axis. The drive motor drives the first roller 11 to rotate, and the welding workpiece placed on the first roller 11 rotates under the drive of the first roller 11.

[0032] To improve the versatility of the support assembly 5, the support frame 10 is connected to an adjusting component. Specifically, the adjusting component includes an adjusting rod 13 and an adjusting wrench 12 located at one end of the adjusting rod 13. The support frame 10 is connected to the adjusting rod 13. By rotating the adjusting wrench 12, the support frame 10 is driven to move along the adjusting rod 13, thereby adjusting the distance between the two support frames 10, and thus changing the axial distance between the two first rollers 11 to accommodate workpieces of different diameters. More specifically, the adjusting rod 13 is a lead screw, and the support frame 10 is provided with a nut that mates with the lead screw. The adjusting wrench 12 is a handwheel. When the handwheel is rotated, the lead screw rotates, driving the nut and the support frame 10 to move linearly along the axial direction of the lead screw, thereby achieving stepless, self-locking adjustment.
