Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to an automatic butt welding equipment for steel structure processing. Background Technology

[0002] Steel structures are widely used in large factories, bridges, and high-rise buildings due to their high strength, light weight, and fast construction speed. During the processing and installation of steel structure components, it is often necessary to butt-weld two steel sections (such as H-beams, I-beams, and channel steel) end-to-end to form beams, columns, and other components that meet length requirements. The quality of the butt weld directly affects the load-bearing capacity and safety of the entire structure; therefore, ensuring the accuracy and efficiency of butt welding is crucial.

[0003] Currently, in steel structure fabrication workshops, the mainstream method for butt welding of steel sections still relies on experienced welders performing manual operations. The typical process is as follows: First, the two steel sections to be butt welded are roughly placed on a platform using hoisting equipment. Then, workers use jacks, crowbars, and other tools to repeatedly adjust the ends of the two steel sections, aligning their joints (including height, axis, and flange straightness). After initial tack welding for fixation, full welding is then performed. This manual butt welding method has many drawbacks:

[0004] 1. Inefficiency: The alignment, adjustment, and fixing processes are time-consuming and labor-intensive, which severely restricts the production cycle.

[0005] 2. Unstable quality: The accuracy of the connection depends heavily on the experience and responsibility of the workers. It is difficult to guarantee that the straightness, parallelism and gap uniformity of each connection will meet high standards, which can easily lead to welding deformation, stress concentration or weld defects.

[0006] 3. High labor intensity and high safety risks: Workers are at risk of pinching, crushing, and arc light and dust hazards when handling heavy steel and welding.

[0007] 4. High dependence on skilled workers, facing pressure from labor shortages and rising costs. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic butt welding device for steel structure processing.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An automatic butt welding equipment for steel structure processing includes a base one and a base two. A welding robot for welding steel structures is mounted on the top of the base one. A rotatable turntable is mounted on the top of the base two. The rotating end of the turntable one has multiple sets of fixing and docking parts for fixing and docking the steel structure. Each fixing and docking part includes a support base fixed to the rotating end of the turntable one and a clamping platform driven by a driver two to one side of the support base. Both ends of the clamping platform are driven by a bidirectional drive mechanism and have clamping arms. The opposite side of the clamping arms is connected by a mounting seat for installing the steel structure to be welded, driven by the driver one. The mounting seat includes a plate one fixed to the rotating end of the driver one and a plate two for installing and fixing the steel structure. Multiple sets of circular array telescopic joints are provided between the plate one and the plate two.

[0011] Preferably, the expansion joint includes an expansion joint, a ball ring, and a ball head. The expansion joint is connected to the side wall of plate one by a hinge. The expansion end of the expansion joint is fixed with a ball ring. The outer spherical wall of the ball head is movably connected to the inner wall of the ball ring, and one side of the ball head is fixed to the side wall of plate two.

[0012] Furthermore, the top outer wall of the base is fixed with a guide rail by bolts, and the bottom fixed end of the welding robot is connected to the outer wall of the guide rail by a drive slide.

[0013] Based on the aforementioned scheme: the welding robot is arranged in multiple groups.

[0014] A preferred embodiment of the aforementioned scheme is that the welding robot includes a turntable two, a plurality of robotic arms sequentially arranged at the rotating end of the turntable two, and a welding part arranged at the end of the last robotic arm.

[0015] As a further aspect of the present invention: the welding part includes a support frame and a rotating frame rotatably connected to the inner side of the support frame via a support shaft. A welding torch for welding is fixed on one side of the rotating frame, and one or more functional modules with different functions are provided on the other side or multiple sides of the rotating frame.

[0016] Meanwhile, an electric motor is fixed to one side of the outer wall of the support frame by bolts, and the output shaft of the electric motor is driven by a gear set and engaged with the outer wall of the support shaft.

[0017] As a preferred embodiment of the present invention: a rotating ring is slidably connected to the inner side of the support frame, and a negative pressure adsorption tube is fixed to the outer wall of the rotating ring. One end of the negative pressure adsorption tube is annular and located around the working area of ​​the welding gun and the functional module, and an air hole is opened at the bottom of the annular area. The other end of the negative pressure adsorption tube is connected to a negative pressure pump with a filter.

[0018] Meanwhile, a rotating ring is slidably connected to the inner side of the support frame, and a negative pressure adsorption tube is fixed to the outer wall of the rotating ring. One end of the negative pressure adsorption tube is annular and located around the working area of ​​the welding gun and the functional module. An air hole is opened at the bottom of the annular area. The other end of the negative pressure adsorption tube is connected to a negative pressure pump with a filter.

[0019] As a preferred embodiment of the present invention: the side wall of the support frame is provided with a rotating ring groove, the inner wall of the groove is slidably connected to a sliding plate, the sliding plate is fixed to the side wall of the rotating ring by bolts, and a tension spring is fastened to the top of the sliding plate, the other end of the tension spring is fastened to the inner wall of the groove, and an electromagnet is fixed to the top outer wall of the sliding plate by bolts, and an electromagnet 2 that cooperates with the electromagnet is fixed to the lower surface of the groove above the electromagnet 1.

[0020] The magnetic poles on opposite sides of electromagnet one and electromagnet two are the same, and the start-stop control of electromagnet one and electromagnet two is the same as the start-stop control logic of the motor.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. This invention fixes steel structural components by setting a fixed docking part. The position of the steel structural components can be adjusted by rotating the mounting base and extending the telescopic joint within the fixed docking part. Combined with the movement of the clamping arm, the steel structural components can be docked, realizing an automatic docking function. At the same time, it can achieve automated welding by cooperating with a welding robot, thereby solving the problems of low efficiency, unstable quality, high labor intensity, and high skill requirements of manual docking welding.

[0023] 2. Based on the welding robot, this invention can utilize the multiple degrees of freedom of the welding robot itself, as well as the rotation of the mounting base driven by driver one, the rotation of the clamping platform driven by driver two, and the rotation of the turntable one to achieve a high degree of relative motion of the steel structure relative to the welding robot, thereby better matching the complex welding paths required for welding some irregular steel structures.

[0024] 3. In this invention, by setting up a welding robot, the welding robot utilizes the mutual rotation of multiple robotic arms and the rotation of the turntable to change the posture of the welding part. Furthermore, the welding robot is connected to the base by a guide rail and a drive slide, thereby further increasing the relative motion freedom of the welding part relative to the steel structure. In addition, by setting up multiple sets of welding robots, different welding positions can be operated simultaneously, further improving welding efficiency.

[0025] 4. This invention sets the welding part as a combination of a welding gun and a functional module, and combines it with the rotation function of the rotating frame, so that the function of the welding part can be switched according to the required welding, cutting, grinding and other scenarios, thereby increasing the functionality of the entire device and meeting the multi-process scenarios of steel structure processing.

[0026] 5. This invention, by setting a negative pressure adsorption tube, can adsorb fumes or debris during processing, ensuring a clean working environment. At the same time, the lifting and lowering of the negative pressure adsorption tube can avoid obstacles when switching functions. In addition, the lifting and lowering of the negative pressure adsorption tube is jointly controlled by electromagnet one, electromagnet two, and tension spring, which is the same as the logic of an electric motor, simplifying the control logic.

[0035] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0036] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] Example 1:

[0038] An automated butt welding equipment for steel structure processing, such as Figures 1-7 As shown, it includes base 1 and base 2;

[0039] The top of the base 1 is equipped with a welding robot 3 for welding steel structures;

[0040] The top of the base 2 is provided with a turntable 4 that can be driven to rotate. The specific driving method of the turntable 4 can be electric, pneumatic, hydraulic, etc., which are conventional methods for those skilled in the art. This embodiment has not made any creative effort on it, so it will not be described in detail. The rotating end of the turntable 4 is provided with multiple sets of fixing and docking parts 5 for fixing and docking the steel structure.

[0041] The fixed docking part 5 includes a support base 11 fixed to the rotating end of the turntable 4 and a clamping platform 9 driven by a driver 12 to one side of the support base 11. Both ends of the clamping platform 9 are driven by a bidirectional drive mechanism 10 and are connected to clamping arms 7. The opposite side of the clamping arms 7 is driven by a driver 6 and is connected to a mounting base 8 for installing the steel structure to be welded.

[0042] In this embodiment, the specific types of driver 6 and driver 12 are not limited. They can be rotary motors, pneumatic motors, hydraulic motors, and other mechanical structures that can perform rotational drive. All of these are existing technologies and are relatively mature. Those skilled in the art can make their own choices according to their needs. This embodiment has not made any creative efforts on these aspects, so they will not be described in detail.

[0043] The mounting base 8 includes a plate 13 fixed to the rotating end of the driver 6 and a plate 2 17 for fixing the steel structure. Multiple sets of circular array expansion joints are provided between the plate 13 and the plate 2 17.

[0044] The expansion joint includes an expansion joint 15, a ball ring 16, and a ball head 18. The expansion joint 15 is connected to the side wall of plate 13 via a hinge 14. The expansion end of the expansion joint 15 is fixed with the ball ring 16. The outer spherical wall of the ball head 18 is movably connected to the inner wall of the ball ring 16, and one side of the ball head 18 is fixed to the side wall of plate 2 17.

[0045] When using this device, the steel structure materials to be welded can be fixed to the mounting bolts of plate 17 using nuts. Then, the position of each steel structure to be welded can be adjusted by controlling the extension and retraction of multiple sets of telescopic joints. After adjustment, the two steel structure parts to be welded are driven to move closer and dock with each other by the bidirectional drive mechanism 10. Then, the entire steel structure is rotated to one side of the welding robot 3 by the drive turntable 4. During welding, the welding robot 3 itself has multiple degrees of freedom, and the drive driver 6 drives the mounting base 8 to rotate, the drive driver 12 drives the platform 9 to rotate, and the turntable 4 rotates to achieve the relative motion of the steel structure parts with multiple degrees of freedom relative to the welding robot 3. Alternatively, the rotational degree of freedom of the turntable 4 can be abandoned, and the next workpiece can be loaded and unloaded while the previous workpiece is being welded.

[0046] This device uses a fixed docking part 5 to fix the steel structure components. The position of the steel structure components can be adjusted by rotating the mounting base 8 and extending and retracting the telescopic joint within the fixed docking part 5. Combined with the movement of the clamping arm 7, the steel structure components can be docked, realizing the automatic docking function. At the same time, it can achieve automated welding by working with the welding robot 3, thus solving the problems of low efficiency, unstable quality, high labor intensity and high skill requirements of manual docking welding.

[0047] In addition, based on the welding robot 3, this device can utilize the multiple degrees of freedom of the welding robot 3 itself, as well as the rotation of the mounting base 8 driven by the first driver 6, the rotation of the platform 9 driven by the second driver 12, and the rotation of the turntable 4 to achieve the relative motion of the steel structure parts with multiple degrees of freedom relative to the welding robot 3, thereby better matching the complex welding paths required for welding some irregular steel structures.

[0048] To solve welding problems; such as Figure 4 As shown, the top outer wall of the base 1 is fixed with a guide rail 19 by bolts, and the bottom fixed end of the welding robot 3 is connected to the outer wall of the guide rail 19 by a drive slide 20.

[0049] The welding robot 3 is arranged in multiple groups, and the welding robot 3 includes a turntable 21, multiple robotic arms 22 arranged sequentially at the rotating end of the turntable 21, and a welding part 23 arranged at the end of the last robotic arm 22.

[0050] During welding, the position of the welding part 23 can be adjusted by rotating the turntable 21 and rotating the multiple robotic arms 22. At the same time, the position of the entire welding robot 3 can be changed by driving the slide block 20 to slide with the guide rail 19.

[0051] This device, by setting up a welding robot 3, utilizes the mutual rotation of multiple robotic arms 22 in the welding robot 3 and the rotation of the turntable 21 to change the posture of the welding part 23. Furthermore, the welding robot 3 is connected to the base 1 via a guide rail 19 and a drive slide 20, thereby further increasing the relative motion freedom of the welding part 23 relative to the steel structure. In addition, by setting up multiple sets of welding robots 3, different welding positions can be operated synchronously, further improving welding efficiency.

[0052] In this embodiment, the steel structure materials to be welded can be fixed to the mounting bolts of plate 2 17 using nuts. Then, the position of each steel structure to be welded can be adjusted by controlling the extension and retraction of multiple sets of telescopic joints. After adjustment, the two steel structure parts to be welded are driven to move closer and dock with each other by the bidirectional drive mechanism 10. Then, the entire steel structure is rotated to one side of the welding robot 3 by driving the turntable 21 to rotate it. During welding, the position of the welding part 23 can be adjusted by the rotation of the turntable 21 and the mutual rotation of multiple robotic arms 22. At the same time, the position of the entire welding robot 3 can be changed by driving the sliding block 20 and the guide rail 19 to slide. During welding, the welding robot 3 itself has multiple degrees of freedom and the drive driver 16 drives the mounting base 8 to rotate, the drive driver 2 12 drives the platform 9 to rotate, and the turntable 4 to rotate to achieve the relative movement of the steel structure parts with multiple degrees of freedom relative to the welding robot 3. Alternatively, the rotational degree of freedom of the turntable 14 can be abandoned, and the next workpiece can be loaded and unloaded while the previous workpiece is being welded.

[0053] Example 2:

[0054] An automated butt welding equipment for steel structure processing, such as Figures 1-7 As shown, in order to solve the functional problem, this embodiment makes the following improvements based on embodiment 1: the welding part 23 includes a support frame 24 and a rotating frame 25 rotatably connected to the inner side of the support frame 24 via a support shaft 28. A welding torch 30 for welding is fixed on one side of the rotating frame 25, and one or more functional modules 33 with different functions are provided on the other side or multiple sides of the rotating frame 25.

[0055] In this embodiment, the specific type of functional module 33 is not limited. The functional module 33 includes any one or more combinations of drilling mechanism, grinding mechanism, and milling mechanism. Furthermore, all of the above mechanisms are existing technologies and will not be described in detail in this embodiment.

[0056] The motor 26 is fixed to one side of the outer wall of the support frame 24 by bolts, and the output shaft of the motor 26 is driven by the gear set 27 to the outer wall of the support shaft 28.

[0057] The inner side of the support frame 24 is slidably connected to a rotating ring 32, and a negative pressure adsorption tube 31 is fixed on the outer wall of the rotating ring 32. One end of the negative pressure adsorption tube 31 is annular and located around the working area of ​​the welding gun 30 and the functional module 33. An air hole 29 is opened at the bottom of the annular area. The other end of the negative pressure adsorption tube 31 is connected to a negative pressure pump with a filter.

[0058] The support frame 24 has a rotating groove 36 on its side wall. A slide plate 37 is slidably connected to the inner wall of the groove 36. The slide plate 37 is fixed to the side wall of the rotating ring 32 by bolts. A tension spring 34 is fastened to the top of the slide plate 37. The other end of the tension spring 34 is fastened to the inner wall of the groove 36. At the same time, an electromagnet 35 is fixed to the top outer wall of the slide plate 37 by bolts. An electromagnet 38 that cooperates with the electromagnet 35 is fixed to the lower surface of the groove 36 above the electromagnet 35.

[0059] The electromagnet 35 and electromagnet 38 have the same magnetic poles on opposite sides, and the start-stop control of electromagnet 35 and electromagnet 38 is the same as the start-stop control logic of motor 26.

[0060] In this embodiment, when the motor 26 is started, it drives the support shaft 28 to rotate through the gear set 27, thereby driving the rotating frame 25 to rotate, so that the welding torch 30 or different functional modules 33 can switch positions to achieve different functions. On the other hand, when the motor 26 is started, electromagnet 1 35 and electromagnet 2 38 are also energized. The magnetic repulsion between electromagnet 1 35 and electromagnet 2 38 pushes the rotating ring 32 downward. The annular part of the negative pressure adsorption tube 31 passes over the path of the welding torch 30 and the rotation of the negative pressure adsorption tube 31 until the welding torch 30 or functional module 33 moves to the working position. Then the motor 26 is disconnected, and electromagnet 1 35 and electromagnet 2 38 are also de-energized. The rotating ring 32 is pulled by the tension spring 34, so that the annular part of the negative pressure adsorption tube 31 is located above and around the working position of the welding torch 30 or functional module 33. Then, during operation, the welding fumes or grinding and cutting debris from the welding torch 30 are adsorbed by the negative pressure of the negative pressure adsorption tube 31.

[0061] This device, by setting the welding part 23 as a combination of welding gun 30 and functional module 33, and combining it with the rotation function of rotating frame 25, can switch the function of welding part 23 according to the required welding, cutting, grinding and other scenarios, thereby increasing the functionality of the entire device and meeting the multi-process scenarios of steel structure processing.

[0062] In addition, this device is equipped with a negative pressure adsorption tube 31, which can adsorb the fumes or debris during processing to ensure a clean working environment. At the same time, the lifting and lowering of the negative pressure adsorption tube 31 can avoid obstacles when switching functions. Furthermore, the lifting and lowering of the negative pressure adsorption tube 31 is jointly controlled by electromagnet 1 35, electromagnet 2 38, and tension spring 34, which has the same logic as the motor 26, simplifying the control logic.

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
