Description

Technical Field

[0001] This invention relates to the field of steel column welding technology, specifically to a steel column welding fixture with a positioning angle adjustment function. Background Technology

[0002] Steel column welding clamps are used for precise positioning and stable clamping of workpieces during the welding process, effectively controlling welding deformation. Modern welding fixtures generally adopt a modular design, including three core modules: clamping components, transmission mechanisms, and positioning devices. They achieve precise control of clamping force through technologies such as gear and toothed plate meshing and hydraulic drive.

[0003] On construction sites for steel structures and bridges, there is often a lack of stable compressed air sources or hydraulic power stations, making it difficult to directly apply clamps that require external power sources. The need for auxiliary equipment such as air supply systems and hydraulic pump stations not only increases equipment investment but also limits operational flexibility and mobility.

[0036] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 An embodiment of the present invention provides a steel column welding fixture with a positioning angle adjustment function, comprising a vertical plate 1, a positioning slide plate 2 slidably connected to the outer wall of the vertical plate 1, a first clamping plate 4 provided at the bottom of the positioning slide plate 2, the first clamping plate 4 being integrally connected to the positioning slide plate 2, second fastening bolts 12 symmetrically arranged on the outer wall of the positioning slide plate 2, a displacement plate 3 movably fitted on the outer wall of the second fastening bolts 12, a second clamping plate 5 provided on the displacement plate 3, the second clamping plate 5 being integrally connected to the displacement plate 3, and a first fastening bolt 9 fixedly connected to the side wall of the positioning slide plate 2. A first nut 10 is threadedly connected to the outer wall of a fastening bolt 9, and a second nut 13 is threadedly connected to the outer wall of a second fastening bolt 12. A fixing ring 16 is fixedly connected to the side wall of the upright plate 1, and an abutment rod 6 is threadedly connected to the fixing ring 16. A first groove 11 is formed on the side wall of the upright plate 1, and a second groove 14 is formed on the side wall of the displacement plate 3. A positioning ring 15 is fixedly connected to the side wall of the upright plate 1, and the positioning ring 15 is movably fitted onto the outer wall of the abutment rod 6. A rotating block 8 is fixedly connected to the top of the outer wall of the abutment rod 6. The bottom of the first clamping plate 4 is in contact with the steel column structure 7, and the top of the second clamping plate 5 is in contact with the steel column structure 7.

[0037] Furthermore, when the first nut 10 does not press against the upright plate 1 and the second nut 13 does not press against the displacement plate 3, the displacement plate 3, the second clamping plate 5, the first clamping plate 4, and the upright plate 1 can be moved and adjusted. The first fastening bolt 9 can move within the first groove 11, and the second fastening bolt 12 can move within the second groove 14. After the two steel column structures 7 are aligned and connected on the horizontal plane, the first clamping plate 4 and the second clamping plate 5 are adjusted to fit against the two steel column structures 7. An upward pressure is applied to the second clamping plate 5 to fix it. Then, by rotating the rotating block 8, the rotating block 8 drives the abutment rod 6 to rotate. Through the thread action between the abutment rod 6 and the fixing ring 16, As the contact rod 6 rotates relative to the fixed ring 16 and moves downward, it passes the positioning ring 15 and approaches and abuts against the first clamping plate 4. The contact rod 6 applies downward pressure to the first clamping plate 4, causing the first clamping plate 4 to press against the steel column structure 7, making the first clamping plate 4 further fit against the steel column structure 7. At this time, the first nut 10 and the second nut 13 are rotated, causing the first nut 10 to press against the vertical plate 1 and the second nut 13 to press against the displacement plate 3. This causes the first nut 10 to press against the fixed displacement plate 3 and the positioning slide plate 2, and the second nut 13 to press against the fixed vertical plate 1 and the positioning slide plate 2, thereby fixing the first clamping plate 4 and the second clamping plate 5. The fixture is securely clamped onto the steel column structure 7. The first clamping plate 4 and the second clamping plate 5 hold and fix the two steel column structures 7, ensuring that the steel columns maintain the correct position and posture during welding. This effectively controls the position and size of the weld joint, avoiding welding defects caused by positioning deviations. Manual operation of the fixture allows for quick clamping and release of the workpiece, significantly reducing non-welding time and enabling operators to complete welding operations efficiently, reducing labor intensity. The fixture has a simple structure, is easy to operate, requires no external power source, and is suitable for on-site welding operations. By adjusting the distance between the first clamping plate 4 and the second clamping plate 5, the fixture can adapt to steel column structures 7 of different sizes, improving the equipment's versatility and expandability. The abutment rod 6 is positioned so that when the first clamping plate 4 and the second clamping plate 5 clamp the steel column structure 7, the connection position of the two steel column structures 7 is directly below the abutment rod 6. When the abutment rod 6 abuts against the first clamping plate 4, the abutment rod 6 acts as a rigid support structure, thereby bearing the reaction force generated by the first clamping plate 4 when clamping and welding the steel column structure 7, preventing the first clamping plate 4 from deforming or being damaged due to excessive force, and ensuring the stable transmission of clamping force. The abutment cooperation between the abutment rod 6 and the first clamping plate 4 makes the force system of the entire fixture more balanced, which not only enhances the overall structural strength of the fixture, but also provides reliable rigid constraints for steel column welding, which helps to improve the stability of welding operations and the welding quality of the final product.

[0038] Please see Figure 1 , Figure 2 , Figure 4 and Figure 8 An embodiment of the present invention provides a steel column welding fixture with a positioning angle adjustment function. The fixture includes a fixing ring 16, a contact rod 6, a positioning slide plate 2, a first clamping plate 4, a displacement plate 3, and a second clamping plate 5 on the upright plate 1. A connecting plate 17 is fixedly connected to the top of the outer wall of the first clamping plate 4. An opening groove 18 is opened on the top of the outer wall of the connecting plate 17. A transmission ring plate 19 is slidably connected to the inner wall of the connecting plate 17. An extrusion block 20 is symmetrically fixedly connected to the outer wall of the transmission ring plate 19. The extrusion block 20 is disposed inside the connecting plate 17. A pressing block 21 is fixedly connected to the top of the outer wall of the first clamping plate 4. The pressing block 21 is in contact with the extrusion block 20. An elastic ring 45 is fixedly connected to the outer wall of the contact rod 6.

[0039] Furthermore, after the first clamping plate 4 and the second clamping plate 5 are attached to the steel column structure 7, the rotating block 8 drives the abutment rod 6 to rotate. While rotating relative to the fixed ring 16, the abutment rod 6 moves downwards, causing the elastic ring 45 to rotate and move downwards simultaneously. The abutment rod 6 gradually inserts into the opening slot 18, and the elastic ring 45 gradually approaches the transmission ring plate 19. After the elastic ring 45 contacts the transmission ring plate 19, as the elastic ring 45 moves, it gradually squeezes the transmission ring plate 19, causing it to gradually deform. The pressure exerted by the elastic ring 45 on the transmission ring plate 19 gradually increases, causing the elastic ring 45 to... As it moves downward and rotates, the elastic ring 45 gradually deforms and drives the transmission ring plate 19 to rotate. The transmission ring plate 19 drives the pressing block 20 to deflect, and the pressing block 20 gradually moves from the side with the lower vertical height of the pressing block 21 to the side with the higher vertical height. This gradually increases the pressure exerted by the pressing block 20 on the pressing block 21, thereby gradually increasing the pressure exerted by the pressing block 21 on the first clamping plate 4, and gradually increasing the pressure exerted by the first clamping plate 4 on the steel column structure 7. Through the pressing of the pressing blocks 20 and the pressing blocks 21 on both sides of the abutting rod 6, the single support point becomes multiple, thereby dispersing the reaction force exerted by the steel column structure 7 and preventing the abutting rod from being pressed. 6. Bending or damage; simultaneously, by setting the squeezing block 20 and pressing block 21, when the operator makes a construction error, the connection position of the two steel column structures 7 is not directly below the abutment rod 6, but above one of the abutment rods 6. At this time, after the abutment rod 6 applies pressure to the first clamping plate 4, the pressure provided by the abutment rod 6 mainly acts on a single steel column structure 7, and the other steel column structure 7 may be in a state of insufficient clamping force, which may cause the first clamping plate 4 to be unable to stably bear the reaction force generated by the two steel column structures 7 at the same time, causing the local area of ​​the first clamping plate 4 to bear excessive concentrated stress, resulting in the first clamping plate 4 producing To prevent deformation or even breakage, the pressing block 20 and pressing block 21 are set up. When the contact rod 6 provides support, the pressing block 20 and pressing block 21 provide auxiliary support, expanding the range of external force provided and ensuring that the external force can be stably transmitted to the two steel column structures 7. While providing stable support, it further avoids bending or damage to the first clamping plate 4. When disassembling the clamp, during the reset process of the transmission ring plate 19 and pressing block 20, the contact rod 6 rotates and moves upward, and the contact rod 6 no longer presses the transmission ring plate 19. The transmission ring plate 19 part outside the connecting plate 17 is manually rotated to reset the transmission ring plate 19 and pressing block 20.

[0040] Please see Figure 1 , Figure 2 , Figure 4 and Figure 7An embodiment of the present invention provides a steel column welding fixture with a positioning angle adjustment function. The first clamping plate 4 has a first threaded groove 23 and a second threaded groove 25 symmetrically opened on its outer wall. The second threaded groove 25 is connected to a fixing bolt 24 by thread. A symmetrical plate 22 is rotatably connected to the side wall of the first clamping plate 4. An outlet groove 28 is opened on the side wall of the symmetrical plate 22. A second connecting body 47 is rotatably connected to the side wall of the symmetrical plate 22. A first connecting body 26 is rotatably connected to the side wall of the second connecting body 47. A threaded hole 27 is opened on the side wall of the first connecting body 26. The thread of the threaded hole 27 matches the thread of the fixing bolt 24. The thread of the fixing bolt 24 matches the thread of the first threaded groove 23.

[0041] Furthermore, after the first clamping plate 4 and the second clamping plate 5 clamp and fix the steel column structure 7, a bolt of the same specification as the fixing bolt 24 can be screwed into the first threaded groove 23 of the first clamping plate 4 and passed out from the outlet groove 28, so that the bolt presses and fixes the steel column structure 7, providing additional clamping points. By pressing and fixing the steel column structure 7 with the bolt, when the edge of the steel column structure 7 is raised or the surface of the steel column structure 7 has impurities and unevenness, the first clamping plate 4 and the second clamping plate 5 will be suspended, with the bottom of the first clamping plate 4 and the top of the second clamping plate 5 suspended. Part of the steel column structure 7 is not in contact with the first clamping plate 4 and the second clamping plate 5, resulting in insufficient clamping force when the steel column structure 7 is clamped and fixed. By screwing the bolt into the first threaded groove 23, the bolt provides additional clamping force, thus ensuring the clamping effect. Furthermore, by screwing the fixing bolt 24 into the first threaded groove 23, and then screwing the front end of the fixing bolt 24 out of the first threaded groove 23 and into the threaded hole 27 of the first connecting body 26, the fixing bolt 24 drives the first connecting body 26, and the first connecting body 26... The second connecting body 47 moves, driving the symmetrical plate 22. The rotational arrangement between the first connecting body 26 and the second connecting body 47 allows the first connecting body 26 to rotate and move downwards with the fixing bolt 24, simultaneously driving only the second connecting body 47 downwards. The rotational arrangement between the second connecting body 47 and the symmetrical plate 22 causes the symmetrical plate 22 to deflect around the axis connecting it to the first clamping plate 4 when the second connecting body 47 drives the symmetrical plate 22, thereby causing the symmetrical plate 22 to compress the steel column structure 7, thus providing clamping for the steel column structure 7. The force provides additional clamping points, further ensuring the clamping effect; by setting the same structure as the first clamping plate 4 on the second clamping plate 5, a stable clamping force is ensured on the steel column structure 7; by applying force to the upper and lower sides of the steel column structure 7 simultaneously, the problem of uneven force that may be caused by clamping in one direction is avoided; when the steel column structure 7 has a certain degree of curvature or uneven surface, the symmetrical plates 22 can be adjusted by their respective deflection angles to effectively abut against the surface of the steel column structure 7 and ensure the clamping effect;

[0042] During welding, if the two steel column structures 7 are connected at a certain angle, before the first clamping plate 4 and the second clamping plate 5 clamp and fix the steel column structure 7, the position of the fixing bolt 24 relative to the first clamping plate 4 is adjusted, the position of the symmetrical plate 22 relative to the first clamping plate 4 is adjusted, and the distance between the first clamping plate 4 and the second clamping plate 5 is adjusted so that the symmetrical plate 22 fits against the steel column structure 7. This allows the clamp to clamp the steel column structure 7 at a certain angle, improving the versatility of the equipment. No additional complex drive device is required; it can be achieved simply by manually tightening the fixing bolt 24. The operation is convenient, and the adjustment accuracy is easy to control. When the connection angle of the steel column structure 7 changes, the operator can flexibly adjust the deflection degree of the symmetrical plate 22 according to actual needs to ensure that the symmetrical plate 22 can form a stable contact with the surface of the steel column structure 7 under different angle conditions, avoiding the problem of clamping loosening due to angle deviation.

[0043] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of the present invention provides a steel column welding fixture with a positioning angle adjustment function. The upright plate 1 is provided with a fixing ring 16, a contact rod 6, a positioning slide plate 2, a first clamping plate 4, a displacement plate 3, a second clamping plate 5, a first fastening bolt 9, a first nut 10, a second fastening bolt 12, and a second nut 13. The bottom of the outer wall of the upright plate 1 is fixedly connected to an installation plate 30, the side wall of the installation plate 30 is slidably connected to a translation plate 29, the side wall of the translation plate 29 is fixedly connected to a first limiting plate 31, and the side wall of the translation plate 29 is fixedly connected to a second limiting plate 32.

[0044] Furthermore, before the clamp holds the steel column structure 7, the first nut 10 is not in contact with the upright plate 1, and the second nut 13 is not in contact with the displacement plate 3. After aligning and connecting the two steel column structures 7, the translation plate 29 comes into contact with the second clamping plate 5, making the first clamping plate 4 and the second clamping plate 5 fit against the two steel column structures 7, ensuring that the connection point of the two steel column structures 7 is below the abutting rod 6. The rotating block 8 drives the abutting rod 6 to rotate, causing the abutting rod 6 to move downwards while rotating, so that the abutting rod 6 abuts against the first clamping plate 4, thereby applying downward pressure to the first clamping plate 4. At the same time, the abutting rod 6 applies upward pressure to the fixing ring 16 and the upright plate 1, the upright plate 1 applies upward pressure to the mounting plate 30 and the translation plate 29, and the translation plate 29 applies upward pressure to the second clamping plate 5, so that the first clamping plate 4 simultaneously squeezes the steel column structure 7, making the first clamping plate 4 and the second clamping plate 5 further fit against the steel column structure 7. To achieve stable clamping of the steel column structure 7, the first nut 10 and the second nut 13 are rotated. The first nut 10 presses against the fixed displacement plate 3 and the positioning slide plate 2, while the second nut 13 presses against the fixed upright plate 1 and the positioning slide plate 2, thus fixing the first clamping plate 4 and the second clamping plate 5. By setting the mounting plate 30 and the translation plate 29, when the abutment rod 6 applies downward pressure to the first clamping plate 4, it simultaneously applies upward pressure to the second clamping plate 5, which facilitates operation and ensures the operation effect. Moreover, when the clamp needs to be removed after welding, it is only necessary to push the translation plate 29 so that the translation plate 29 does not contact the second clamping plate 5. Thus, it is only necessary to loosen the two second nuts 13 to adjust the second clamping plate 5 and release the clamping of the steel column structure 7, achieving quick disassembly without operating the first nut 10 and the rotating block 8. By setting the first limit plate 31 and the second limit plate 32, separation of the translation plate 29 and the mounting plate 30 is prevented.

[0045] Please see Figure 1 , Figure 6 , Figure 7 and Figure 9One embodiment of the present invention provides a steel column welding fixture with a positioning angle adjustment function. The outer wall of the fixing bolt 24 is fitted with an alignment ring 42. A rotating body 36 is slidably connected to the outer wall of the alignment ring 42. A movable body 41 is rotatably connected to the top of the outer wall of the rotating body 36. A disassembly frame 34 is slidably connected to the outer wall of the movable body 41. A rotating toothed plate 37 is fixedly connected to the outer wall of the rotating body 36. A rotating gear 46 is meshed with the side wall of the rotating toothed plate 37. The disassembly frame 34 is rotatably connected to the side wall of the rotating gear 46. The rotating gear 46 is connected to a first [unclear - possibly a type of rotating shaft]. A bevel gear 38 is provided, and a second bevel gear 39 is meshed with the side wall of the first bevel gear 38. The second bevel gear 39 is fixedly mounted on the outer wall of the transmission rod 35. A disassembly frame 34 is rotatably connected to the outer wall of the transmission rod 35, and a rotating handle 33 is fixedly connected to the side wall of the transmission rod 35. A moving groove 40 is provided at the bottom of the outer wall of the disassembly frame 34, and the moving groove 40 is movably mounted on the outer wall of the rotating body 36. A limiting body 44 is symmetrically fixedly connected to the outer wall of the alignment ring 42, and a limiting groove 43 is provided on the inner wall of the rotating body 36, and the limiting groove 43 is movably mounted on the outer wall of the limiting body 44.

[0046] Furthermore, during welding, if the two steel column structures 7 to be aligned have a certain angle, before the first clamping plate 4 and the second clamping plate 5 clamp and fix the steel column structure 7, move the contact rod 6 away from the first clamping plate 4, and initially screw the two fixing bolts 24 into the first threaded groove 23 of the first clamping plate 4. Fine-tune the fixing bolts 24 so that the fixing bolts 24 are aligned and matched with the alignment ring 42. Move the disassembly frame 34 so that the fixing bolts 24 are inserted into the alignment ring 42. At this time, rotate the rotating handle 33. The rotating handle 33 drives the transmission rod 35 to rotate. The transmission rod 35 drives the second bevel gear 39 to rotate. The second bevel gear 39 drives the first bevel gear 38 to rotate. The first bevel gear 38 drives the rotating gear 46 to rotate through the rotating shaft. The rotating gear 46 drives the rotating gear plate 37 to rotate. 37 drives the rotating body 36 to rotate, the rotating body 36 drives the alignment ring 42 to rotate, the alignment ring 42 drives the fixing bolt 24 to rotate, so that the front end of the fixing bolt 24 gradually unscrews out of the first thread groove 23 and screws into the threaded hole 27. The fixing bolt 24 drives the first connecting body 26, the first connecting body 26 drives the second connecting body 47, and the second connecting body 47 drives the symmetrical plate 22. By synchronously rotating the fixing bolt 24, the symmetrical plate 22 is synchronously adjusted, so that the adjustment angles of the two symmetrical plates 22 on the first clamping plate 4 are consistent to a certain extent. Thus, after the symmetrical plate 22 is attached to the steel column structure 7, the relative level of the first clamping plate 4 can be guaranteed, and the pressure applied by the abutment rod 6 to the first clamping plate 4 is not uneven, which would cause deformation of the equipment.

[0047] When adjusting the structure of the corresponding symmetrical plate 22 on the second clamping plate 5, the rotating body 36 needs to be moved so that it moves within the moving groove 40, bringing the two rotating bodies 36 closer together and engaging the rotating toothed plate 37 on the rotating body 36 with the rotating gear 46 on the other side. At this time, the two fixing bolts 24 are screwed into the first threaded groove 23 of the second clamping plate 5 through the same steps described above. In addition, the alignment ring 42 can be rotated and moved so that the limiting body 44 is removed from the limiting groove 43, thereby removing the alignment ring 42. By replacing the alignment ring 42 with different specifications, the fixing bolts 24 of different specifications can be operated.

[0048] Working principle: When clamping the steel column structure 7, if the two steel column structures 7 are joined together at 180 degrees, the steel column structure 7 is placed between the first clamping plate 4 and the second clamping plate 5. Adjust the rotating block 8 so that the rotating block 8 drives the abutment rod 6 to rotate and move downward at the same time. The abutment rod 6 abuts the first clamping plate 4 downward, and the translation plate 29 abuts the second clamping plate 5 upward. Tighten the first nut 10 and the second nut 13, and the first clamping plate 4 and the second clamping plate 5 clamp the steel column structure 7.

[0049] As the contact rod 6 drives the elastic ring 45 to rotate, it moves downward. After the elastic ring 45 contacts the transmission ring plate 19, the elastic ring 45 gradually deforms and drives the transmission ring plate 19 to deflect. The transmission ring plate 19 drives the pressing block 20. The pressing block 20 moves from the lower side of the pressing block 21 to the higher side, so that the pressing block 20 presses the pressing block 21, and the pressing block 21 presses the first clamping plate 4.

[0050] If the two steel column structures 7 are joined at a certain angle, i.e. not 180 degrees, the fixing bolt 24 is initially screwed into the first threaded groove 23, the fixing bolt 24 is inserted into the alignment ring 42, and the rotating handle 33 is rotated. The rotating handle 33 drives the transmission rod 35, the second bevel gear 39, the first bevel gear 38, the rotating gear 46, the rotating tooth plate 37, the rotating body 36, the alignment ring 42, and the fixing bolt 24. The fixing bolt 24 drives the first connecting body 26, the second connecting body 47, and the symmetrical plate 22, so that the symmetrical plate 22 fits against the steel column structure 7.
