Description

Technical Field

[0002] In the welding operation of H-beam, it is very difficult to achieve convenient welding positioning and post-welding correction positioning. H-beams are usually large in size and heavy in weight, which makes it difficult to achieve accurate positioning during welding. Traditional positioning methods are often difficult to adapt to such product specifications and are prone to deviations. In addition, the shape of H-beams is complicated, and there are multiple planes and angles that need to be welded, which further increases the difficulty of positioning. The welding requirements and angle adjustment of different parts must be considered. During the welding process, due to the influence of high temperature and thermal stress, H-beams are prone to deformation, which causes the offset of the welding position, causing adverse effects on welding quality and positioning accuracy. At the same time, in the vehicle manufacturing industry, there are also various forms of beams with W-shaped length direction and H-shaped or rectangular cross-sectional shapes. It is more difficult to fix and clamp them. In addition, it is also difficult to provide effective positioning support in the later correction stage. The welding of H-beams generally needs to be carried out in a wide working space, but in actual operation, it may be restricted by factors such as site and equipment, making the positioning operation more difficult.

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] Reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, provides an H-beam automatic welding and post-welding correction equipment for welding and post-welding correction of steel beams, wherein the steel beam has a side beam portion 101, a middle beam portion 102 and an edge portion 103, wherein the edge portion 103 is located on both sides of the side beam portion 101, and the side beam portion 101 and the edge portion 103 are arranged in pairs, including a body 2, the body 2 has a welding channel 201, the welding channel 201 is used to accommodate the steel beam, and the bottom of the welding channel 201 has a first through groove; a welding head 3 is arranged in the welding channel 201, and the welding head 3 faces one side of the bottom wall of the middle beam portion 102; a conveying roller member 4 is rotatably arranged on the body 2 and extends into the welding channel 201, and the conveying roller member 4 is used to roll and abut with the side beam portion 101 at the bottom of the steel beam; a top pressure roller member 5 is lifted and slidably arranged in the welding channel 201, and the top pressure roller member 5 is configured to roll and abut with or cancel the abutment with the side beam portion 101 at the top of the steel beam after lifting and sliding.

[0023] In this embodiment, when performing welding operation, the steel beam is first pre-welded by two side beam plates and one or more middle beam plates, and then the H-shaped steel beam is placed in the welding channel 201 by a transport trolley. The conveying roller member 4 rotates and rolls against the side beam portion 101 at the bottom of the steel beam to push the steel beam forward. The top pressure roller member 5 descends and rolls against the side beam portion 101 at the top of the steel beam to stably fix the steel beam in a suitable position. The welding head 3 performs welding operation on the bottom wall of the middle beam portion 102. When the welding is completed and needs to be corrected, the top pressure roller member 5 rises to cancel the abutment, and the conveying roller member 4 continues to push the steel beam to move for subsequent processing. The cooperation of the conveying roller member 4 and the top pressure roller member 5 can effectively fix the position of the steel beam and ensure the positioning accuracy during welding and correction. It can also enable the conveying roller member 4 to ensure that the steel beam moves smoothly in the welding channel 201, reducing shaking and deviation. The stable fixing method helps to reduce the deformation of the steel beam caused by high temperature and thermal stress and ensure the welding quality. The automated conveying and fixing method improves the work efficiency of welding and correction. The lifting height of the top pressure roller 5 and the rotation speed of the conveying roller 4 can be adjusted to adapt to H-shaped steel beams of different sizes, and at the same time, it can also have a good matching and supporting effect on steel beams of other shapes.

[0024] Furthermore, it also includes a first lifting slider 6 that is lifted and slidably arranged on the machine body 2; a first side pressure slide 7 that is horizontally slidable and rotatable arranged on the first lifting slider 6, and a welding head 3 that is arranged on the first side pressure slide 7; a first side pressure roller 8 that is rotatably arranged on the first side pressure slide 7, and the first side pressure roller 8 is configured to be driven by the first side pressure slide 7 to slide horizontally and then be used to roll and abut or cancel the abutment with the edge 103 on one side of the steel beam.

[0025] In this embodiment, the first lifting slider 6, the first side pressure slide 7 and the first side pressure roller 8 are also included. The first lifting slider 6 can be lifted and slid on the machine body 2, the first side pressure slide 7 is horizontally slidable and rotatably arranged on the first lifting slider 6, the welding head 3 is mounted on the first side pressure slide 7, and the first side pressure roller 8 is rotatably arranged on the first side pressure slide 7. During the welding and correction process, the first lifting slider 6 is lifted and adjusted according to the height of the steel beam. The first side pressure slide 7 drives the first side pressure roller 8 to slide horizontally, so that it rolls and abuts against the edge 103 on one side of the steel beam, thereby enhancing the stability and positioning accuracy of the steel beam. When abutment is not required, the first side pressure slide 7 drives the first side pressure roller 8 to slide horizontally to cancel the abutment. The abutment of the first side pressure roller 8 with the edge 103 of the steel beam further improves the positioning accuracy of the steel beam during welding and correction. The setting of the first lifting slider 6 can adapt to steel beams of different heights, thereby increasing the versatility of the equipment. The horizontal sliding and rotation of the first side pressure slide 7 make the position adjustment of the first side pressure roller 8 more flexible, thus meeting the requirements of different working conditions. Increased support and fixation on the side of the steel beam makes the steel beam more stable during welding and correction, reducing shaking and deviation. Accurate positioning helps improve welding quality and reduce welding defects.

[0026] Furthermore, the first side pressure roller 8 has an inner concave clamping portion 801 , and the inner concave clamping portion 801 is used to clamp the edge portion 103 and roll and abut against it.

[0027] In this embodiment, when the equipment is running, the first side pressure slide 7 drives the first side pressure roller 8 to slide horizontally, so that the edge 103 of the steel beam is clamped into the concave clamping part 801 of the first side pressure roller 8, and rolling contact is achieved. When processing a beam that is not linear in the length direction, the rotatable setting of the first side pressure slide 7 and the first side pressure roller 8 can flexibly adjust the angle and position according to the shape and direction of the beam. When the beam moves, its edge 103 can be smoothly clamped into the concave clamping part 801 of the first side pressure roller 8 to achieve continuous rolling contact. In this process, the conveying roller member 4 continuously pushes the beam forward, and the welding head 3 performs welding operations. The concave clamping part 801 can make the edge 103 clamped more accurately, further improving the positioning accuracy. The edge 103 is clamped into the concave clamping part 801, which increases the contact area and friction, making the steel beam more stable during welding and correction. It effectively avoids the lateral deviation of the steel beam that may occur during the operation, and ensures the accuracy of welding and correction. Stable clamping reduces the potential safety hazards caused by the shaking of the steel beam. It can handle beams that are not linear in length, which expands the application range of the equipment. It ensures that the complex beams are always held and conveyed in a stable state. Continuous and stable conveying and clamping provide a strong guarantee for high-quality welding.

[0028] Furthermore, the first side pressure rollers 8 are arranged in pairs, and the two first side pressure rollers 8 are both rotatably arranged on the first side pressure slide 7, and the concave clamping parts 801 of the two first side pressure rollers 8 are used to roll and abut against the same edge 103 or roll and abut against two edges 103 on the same side respectively.

[0029] In this embodiment, when the equipment is working, according to the specific situation of the steel beam, the concave clamping parts 801 of the two first side pressure rollers 8 can roll and abut against the same edge 103 to enhance the clamping and positioning of the edge 103; or they can roll and abut against the two edges 103 on the same side respectively, so as to fix and position the steel beam more comprehensively. The first side pressure rollers 8 arranged in pairs increase the contact points and clamping force with the edge 103 of the steel beam, greatly improving the stability of the clamping. Different abutment methods can be selected according to the specific structure and size of the steel beam to adapt to various types of steel beams. More comprehensive and stable clamping helps to further improve the positioning accuracy of the steel beam during welding and correction. The two first side pressure rollers 8 work together to disperse the pressure on the steel beam and reduce the deformation that may be caused by excessive local pressure. Stable and accurate clamping and positioning provide strong support for high-quality welding and correction effects.

[0030] Furthermore, it also includes a second lifting slider 9 that is lifted and slidably set on the machine body 2 and is located on one side of the first lifting slider 6; a second side pressure slide 10 is horizontally slidably set on the second lifting slider 9; a second side pressure roller 11 is rotatably set on the second side pressure slide 10, and the first side pressure roller 8 is configured to be used for rolling contact or cancellation of contact with the middle beam part 102 on one side of the steel beam after horizontal sliding.

[0031] In this embodiment, during operation, for beams of different shapes, such as beams with bends, broken lines, etc., the first lifting slider 6 and the second lifting slider 9 can be lifted and lowered accordingly according to the height change of the beam. The first side pressure slide 7 and the second side pressure slide 10 can slide horizontally, driving the first side pressure roller 8 and the second side pressure roller 11 to move, so that they can accurately abut against different parts of the beam. At the same time, the first side pressure roller 8 and the second side pressure roller 11 can rotate to adapt to the movement and position change of the beam during the conveying process. It can adapt to beams of various shapes, including but not limited to non-standard shapes such as bends and broken lines, greatly expanding the scope of application of the equipment. Through flexible adjustment capabilities, it is possible to achieve accurate positioning and fixation of beams of different shapes, ensuring the accuracy of welding and correction. There is no need to replace equipment or make complex adjustments for beams of different shapes, saving time and manpower and improving work efficiency. More comprehensive fixation helps to reduce shaking and deviation during welding and improve welding quality.

[0032] Furthermore, the first side pressure roller 8, the first side pressure slide 7 and the first lifting slider 6 together constitute a first side pressure assembly 800, the second side pressure roller 11, the second side pressure slide 10 and the second lifting slider 9 together constitute a second side pressure assembly 900, the first side pressure assembly 800 and the second side pressure assembly 900 are arranged in pairs, and the two groups of first side pressure rollers 8 and second side pressure rollers 11 are respectively located on both sides of the steel beam.

[0033] In this embodiment, during welding and correction operations, the paired first side pressure components 800 and the second side pressure components 900 located on both sides of the steel beam work simultaneously. The first lifting slider 6 and the second lifting slider 9 are lifted and lowered according to the height of the steel beam, so that the first side pressure roller 8 and the second side pressure roller 11 are aligned with the corresponding parts of the steel beam. The first side pressure slide 7 and the second side pressure slide 10 slide horizontally, driving the first side pressure roller 8 and the second side pressure roller 11 to approach the steel beam and abut against it, and fix and position the steel beam from both sides. The fixing and positioning effects are applied simultaneously from both sides of the steel beam, which greatly improves the stability of the steel beam during welding and correction, and reduces shaking and displacement. The first side pressure components 800 and the second side pressure components 900 arranged in pairs make the forces on both sides of the steel beam uniform, avoiding deformation or deviation caused by unilateral force. The synergistic effect of the two sides can more accurately determine the position of the steel beam and improve the accuracy of welding and correction. It is suitable for steel beams of different shapes, sizes and welding requirements, and improves the versatility and flexibility of the equipment. Stable and accurate fixed positioning reduces the time of adjustment and calibration, thereby improving the overall work efficiency.

[0034] Furthermore, it also includes a first elastic member 12 with one end arranged on the first lifting slider 6 and the other end arranged on the first side pressure slide 7, providing a force for the first side pressure slide 7 to slide away from the first lifting slider 6; a second elastic member 13 with one end arranged on the second lifting slider 9 and the other end arranged on the second side pressure slide 10, providing a force for the second side pressure slide 10 to slide away from the second lifting slider 9.

[0035] In this embodiment, when supporting the workpiece, if the driving is inaccurate, causing the first side pressure slide 7 and the second side pressure slide 10 to slide beyond expectations, the elastic member will absorb the excess force through its own expansion and contraction to avoid hard collisions and damage between the components. When the size of the workpiece fluctuates to a certain extent, the elastic member can adapt to this change by expansion and contraction, always maintaining effective support and positioning of the workpiece, while preventing damage to the device or the workpiece due to unstable workpiece size. It effectively avoids damage to the internal components of the device due to inaccurate driving, and improves the reliability and stability of the equipment. It can cope with the instability of the workpiece size, ensure that the equipment can work normally under different working conditions, and reduce the adverse effects caused by changes in the workpiece size. It reduces the wear and damage of components caused by accidental impact and excessive extrusion, and reduces the maintenance and replacement costs of the equipment.

[0036] Furthermore, it also includes a second rotating frame 14 rotatably set on the body 2, the second rotating frame 14 rotates synchronously with the conveying roller 4, and the second rotating frame 14 has a second guide groove 1401 along the rotation radial direction; the third slider 15 is slidably set in the second guide groove 1401; the supporting roller 16 is rotatably set on the third slider 15, and the supporting roller 16 is used for rolling abutment with the side beam part 101 at the bottom of the steel beam; one end of the third elastic member 17 is set on the inner wall of the second guide groove 1401, and the other end is set on the third slider 15, providing a force for the third slider 15 to slide in the direction away from the rotation center of the second rotating frame 14.

[0037] In this embodiment, when facing a special-shaped steel beam with an M-shaped length direction, for example, when the conveying roller member 4 cannot provide effective bottom support for certain positions, the second rotating frame 14 rotates synchronously with the conveying roller member 4, and multiple conveying roller members 4 are synchronously conveyed through chain sprockets. Gears or pulleys are set on the conveying roller member 4 and the second rotating frame 14 to achieve a transmission connection with an adjustable transmission ratio. Due to the force provided by the third elastic member 17, the third slider 15 will slide in the direction away from the rotation center of the second rotating frame 14, driving the supporting roller 16 to move to a suitable position, rolling and abutting with the side beam portion 101 at the bottom of the steel beam, providing effective bottom support, and can also assist the conveying roller member 4 in providing conveying power at the turning point, so that the operation of the device is more stable. For the position where the conveying roller member 4 of the special-shaped steel beam is insufficiently supported, additional and effective bottom support is provided to ensure the stability of the steel beam. The setting of the third elastic member 17 enables the supporting roller 16 to adapt to the shape and position changes of the steel beam to ensure close abutment. The synchronous rotation with the conveying roller member 4 ensures the coordination of the entire support system and avoids the support instability caused by asynchronism. Stable bottom support helps improve the accuracy and quality of welding and correction, and reduces errors caused by unstable support.

[0038] Furthermore, the first side pressure slide 7 and the first lifting slide block 6 have an inner channel 701 , and the welding head 3 has a welding pipe 301 , and the welding pipe 301 passes through the inner channel 701 .

[0039] In this embodiment, during welding operation, the welding pipe 301 accurately transports the welding material to the welding position through the inner channel 701 of the first side pressure slide 7 to perform welding operation. The welding pipe 301 passes through the inner channel 701, making the line layout more regular and reducing the interference and safety hazards that may be caused by the clutter of the pipeline. The inner channel 701 provides a certain protection for the welding pipe 301 and reduces the risk of damage to the pipeline by external factors. It helps to stabilize the position of the welding pipe 301 and ensure the stable transportation of welding materials, thereby improving the welding quality. The internal space of the first side pressure slide 7 is reasonably utilized to make the overall structure of the equipment more compact. The regular layout and protection measures make the maintenance and replacement of the welding pipe 301 more convenient and quick.

[0040] Furthermore, it also includes a linear driving member 18 disposed on the machine body 2, and there are a plurality of linear driving members 18, which are respectively used to drive the first side pressure slide 7, the second side pressure slide 10 and the top pressure roller member 5 to slide.

[0041] In this embodiment, when the equipment is running, different linear drive components 18 work separately. When the first side pressure slide 7 needs to slide, the corresponding linear drive component 18 is started to push or pull the first side pressure slide 7 to move horizontally. Similarly, the linear drive component 18 responsible for the second side pressure slide 10 and the top pressure roller component 5 also acts at the corresponding time to drive them to slide to the specified position. Each component has a dedicated linear drive component 18, which can achieve independent and precise position control, thereby improving the flexibility and adaptability of the equipment. The sliding of each component can be controlled simultaneously or separately, which reduces the adjustment time and improves the work efficiency. Independent drive components facilitate troubleshooting and maintenance, reducing maintenance costs and downtime. If more similar sliding components need to be added, only the corresponding linear drive components 18 need to be added, which is convenient for upgrading and improving the equipment.
