Description

Technical Field

[0001] This utility model relates to the field of steel column production technology, and in particular to a welding torch support device for steel column welding. Background Technology

[0002] H-beams are an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. They are named for their cross-section, which resembles the letter "H".

[0003] When producing H-beam columns, the flange plates and web plates need to be assembled together, usually by welding. Before welding the flange plates and web plates, spot welding is required to temporarily fix them in place and prevent displacement or misalignment during subsequent welding. Spot welding is typically done manually by holding a welding torch at the joint between the flange plates and web plates. During welding, the operator must observe and ensure the accurate assembly position of the flange plates and web plates. However, due to the long overall length of H-beam columns, manual welding with a torch for extended periods is time-consuming and laborious. Furthermore, it is difficult to control the uniform and regular distribution of weld points during manual spot welding. Regular and uniform weld points are crucial for ensuring the connection strength between the flange plates and web plates and the regularity of the subsequent welding path. Therefore, the overall welding effect of H-beams needs further improvement.

[0004] Therefore, we propose a welding torch support device for steel column welding. Utility Model Content

[0026] A welding torch support device for welding steel columns, such as Figure 1 - Figure 6As shown, the system includes a conveyor 1, which is used to transport the flanges and webs during spot welding of H-beam steel columns. A fixed frame 2 is fixedly installed on one side of the conveyor 1, and the fixed frame 2 is fixedly connected to the conveyor 1 by fasteners. An installation platform 4 is movably installed on the fixed frame 2, and an adjustment component is provided on the fixed frame 2 to flexibly adjust the angle of the installation platform 4. During spot welding of the flanges and webs, the angle of the installation platform 4 can be adjusted by the adjustment component for subsequent spot welding operations. A fixed seat 5 is movably installed on the installation platform 4, and a welding torch 3 is provided on the fixed seat 5.

A clamping component is also included, which clamps and fixes the welding torch 3 to the mounting base 5 during the assembly of the H-beam column. After the welding torch 3 is clamped and fixed in place, the angle of the welding torch 3 can be flexibly adjusted using the adjustment component to ensure that the welding torch 3 faces the joint between the flange and the web. Simultaneously, during the welding process, the adjustable intermittent drive component on the mounting platform 4 enables intermittent welding of the welding torch 3 and allows adjustment of the spot welding frequency to flexibly change the distance between each two weld points, thus adapting to the welding requirements of different H-beam columns.

[0027] Furthermore, the adjustment assembly includes a worm gear 21, which is rotatably mounted on a fixed frame 2 and driven by a motor. A worm wheel 22 is rotatably mounted on the fixed frame 2 and meshes with the worm gear 21. A second worm gear 25 is rotatably mounted on the fixed frame 2 and driven by a motor. A second worm wheel 24 is rotatably mounted on the fixed frame 2 and meshes with the worm gear 25. A sleeve shaft 23 is fixedly mounted on the worm wheel 22, and a connecting cylinder 26 is fixedly mounted on the worm wheel 24. A connecting frame 27 is fixedly mounted on the top of the connecting cylinder 26. The sleeve shaft 23 passes through the interior of the connecting cylinder 26 and extends into the interior of the connecting frame 27. A bevel gear 28 is fixedly mounted on the end of the sleeve shaft 23 that extends into the interior of the connecting frame 27. The unit is rotatably mounted with a second bevel gear 29, which meshes with a first bevel gear 28. The second bevel gear 29 is fixedly connected to the mounting platform 4 via a fixed shaft. An adjustment assembly is provided so that when welding the flanges and webs of the H-beam column using the welding torch 3, the longitudinal angle of the welding torch 3 can be adjusted via the worm gear 21 in conjunction with the worm wheel 22, the sleeve shaft 23, the first bevel gear 28, and the second bevel gear 29. Simultaneously, the transverse angle of the welding torch 3 can be adjusted via the worm gear 25 in conjunction with the worm wheel 24, the connecting cylinder 26, and the connecting frame 27. This allows for flexible multi-angle adjustment and switching of the welding torch 3 during spot welding operations, enabling adaptability when welding H-beam columns of different specifications and improving the applicability of the device.

[0028] Furthermore, the clamping assembly includes a positioning plate 55, which is movably installed inside the fixed base 5. The positioning plate 55 can move up and down inside the fixed base 5. A second spring 56 is fixedly installed inside the fixed base 5, and one end of the second spring 56 is fixedly connected to the positioning plate 55. An arc-shaped groove is provided on the welding torch 3 to facilitate the grip of the operator. The positioning plate 55 can be inserted into the arc-shaped groove on the welding torch 3. A positioning short shaft is fixedly installed inside the fixed base 5. The positioning short shaft is sleeved with the second spring 56 and the positioning plate 55. Upper pressure frames 51 are slidably installed on both sides of the fixed base 5. The upper pressure frames 51 can move laterally on the fixed base 5. A first spring 52 is fixedly installed on the fixed base 5, and one end of the first spring 52 is fixedly connected to the upper pressure frame 51. A positioning short shaft is also fixedly installed on the fixed base 5 at the position corresponding to the first spring 52. The positioning short shaft is sleeved with the first spring 52 and the upper pressure frame 51. An external plate is fixedly installed on one side of the positioning short shaft. A threaded short shaft 53 is threadedly connected to the external plate. The threaded short shaft 53 is threadedly connected to the upper pressure frame 51. The upper pressure frame 51 has a threaded hole, which is threadedly connected to the threaded short shaft 53. An ejector block 54 is fixedly installed on the upper pressure frame 51. The ejector block 54 has a trapezoidal cross-section and can contact the clamping plate 55 and press the clamping plate 55 to move upward. By setting up a clamping assembly, during welding, when using the welding torch 3... During spot welding, the welding torch 3 is placed inside the fixed base 5, with both sides of the welding torch 3 in contact with the inner wall of the fixed base 5. At the same time, the upper pressure frame 51 on both sides clamps the welding torch 3 at the top position, and the clamping plate 55 pushes the welding torch 3 upward. The ejector block 54 limits the clamping plate 55, thereby achieving the clamping and limiting of the welding torch 3. When using the welding torch 3 for spot welding, there is no need for the operator to hold it, freeing the operator's hands and making the operation more convenient.

[0029] Furthermore, the adjustable intermittent drive assembly includes a movable gear 43, which is rotatably mounted on a mounting platform 4. A movable seat 41 is rotatably mounted on the mounting platform 4, and the movable seat 41 is fixedly connected to the movable gear 43 via a rotating shaft. The movable seat 41 is also fixedly connected to a fixed seat 5. A movable gear plate 42 is rotatably mounted on the mounting platform 4, and the movable gear plate 42 meshes with the movable gear 43. A movable frame 44, which is an arc-shaped ring structure, is fixedly mounted on the movable gear plate 42. A drive shaft 45 is rotatably mounted on the mounting platform 4, and the drive shaft 45 is driven by a servo motor. A connecting plate 46 is fixedly mounted on the drive shaft 45, and an adjusting shaft 47 is slidably mounted on the connecting plate 46. The adjusting shaft 47 and the connecting plate 46 can be fixed with fasteners. The frame 44 is slidably connected; by setting an adjustable intermittent drive component, when using the welding torch 3 for spot welding, the drive shaft 45 is controlled to rotate, which drives the adjustment shaft 47 to rotate synchronously, and drives the movable frame 44 to move synchronously, which can drive the movable toothed plate 42 to swing back and forth. While the movable toothed plate 42 swings, it can drive the movable seat 41 and the welding torch 3 to make regular swinging movements by meshing with the movable gear 43. When the welding torch 3 moves to the joint between the flange and the web, the welding torch 3 can perform spot welding operation at the joint position, so as to perform spot welding operation on the flange and the web by controlling the regular swing of the welding torch 3. At the same time, the position of the adjustment shaft 47 can be adjusted to adjust the swing amplitude of the movable frame 44 and the movable toothed plate 42, thereby realizing the control of the spot welding frequency to suit the welding needs of H-beams of different specifications.

[0030] The working principle of this utility model is as follows: When welding H-shaped steel columns, the flange and web are placed on the conveyor 1 for conveying, and the web is limited by an external roller group to ensure that the flange and web are in close contact.

[0031] Before welding, the welding torch 3 is placed inside the fixed seat 5. The clamping plate 55 contacts the arc-shaped groove on the welding torch 3. The upper pressure frame 51 on both sides slides towards the middle position under the elastic force of the spring 52 and fits together to limit the welding torch 3 from the upper position. While the upper pressure frame 51 slides towards the middle position, the ejector block 54 presses the clamping plate 55 to move upward and drives the welding torch 3 to move upward and lift it up to fit together with the upper pressure frame 51. At this time, the two sides of the welding torch 3 are limited and clamped by the fixed seat 5. The top and bottom of the welding torch 3 are limited and fixed by the cooperation of the upper pressure frame 51 and the clamping plate 55. The rotating threaded short shaft 53 is threadedly connected to the upper pressure frame 51 to limit the position of the upper pressure frame 51. The welding torch 3 is clamped and fixed.

[0032] Based on the specifications of the H-shaped steel column and the actual welding conditions on site, the motor drives the worm gear 21 to rotate. When the worm gear 21 rotates, it meshes with the worm wheel 22 to drive the worm wheel 22 to rotate. When the worm wheel 22 rotates, it drives the sleeve shaft 23 to rotate. When the sleeve shaft 23 rotates, it drives the connecting frame 27 to rotate synchronously and meshes with the bevel gear 29 to drive the bevel gear 29 and the mounting platform 4 on it to rotate synchronously for longitudinal angle adjustment. At the same time, the motor drives the worm gear 25 to rotate. When the worm gear 25 rotates, it meshes with the worm wheel 24 and drives the worm wheel 24 to drive the connecting cylinder 26 to rotate synchronously. When the connecting cylinder 26 rotates, it drives the connecting frame 27 to drive the mounting platform 4 to rotate synchronously for transverse angle adjustment. By adjusting the angle of the welding torch 3 in both the transverse and longitudinal directions, the welding torch 3 is aligned with the joint between the flange and the web.

[0033] During welding, the welding torch 3 can be started to weld at the joint between the flange and the web. During welding, the servo motor drives the drive shaft 45 to rotate. When the drive shaft 45 rotates, it drives the adjusting shaft 47 to rotate synchronously. When the adjusting shaft 47 rotates, it drives the movable frame 44 to swing synchronously. When the movable frame 44 swings, it drives the movable toothed plate 42 to swing synchronously. When the movable toothed plate 42 swings, it can drive the movable seat 41 to make the welding torch 3 swing regularly by meshing with the movable gear 43. When the welding torch 3 swings regularly, it can switch positions between the joint and the other end. When the welding torch 3 swings to the flange and the web... At the joint, the flange and web can be welded. When the welding torch 3 swings to the other end, the welding of the flange and web can be stopped. During welding, the flange and web can be spot welded by the regular swing of the welding torch 3. At the same time, during spot welding, the distance between the drive shaft 45 and the adjustment shaft 47 can be adjusted according to the distribution spacing of the spot welds of different specifications of H-beams to adjust the swing amplitude of the movable frame 44 and the movable toothed plate 42. After the swing amplitude of the movable frame 44 and the movable toothed plate 42 is adjusted, the swing amplitude of the welding torch 3 can be adjusted to adjust the frequency of spot welding.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
