[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0039] In order to improve the positioning speed and centering accuracy of the web and flange plates, as an embodiment of the present invention, Figure 1 、 Figure 2As shown, the present invention is an adjustable manual assembly platform for arc H-shaped steel welding, comprising several groups of vertically arranged positioning clamps 1, a first slot 2 for positioning the H-shaped steel flange plate is horizontally penetrated on the positioning clamp 1, the lower surface of the middle part of the first slot 2 is connected with a second slot 3 for positioning the H-shaped steel web, a centering bolt 4 and a straightening bolt 5 are horizontally arranged on one side of the second slot 3, the centering bolt 4 is located above the straightening bolt 5, and the centering bolt 4 and the straightening bolt 5 are both threaded with several groups of nuts 6, the nuts 6 are fixedly connected to one side of the positioning clamp 1, and two pads 7 are provided on the side of the second slot 3 away from the nut 6, both of which are fixedly connected to the positioning clamp 1, the two pads 7 are used to work together with the centering bolt 4 and the straightening bolt 5 to act on the H-shaped steel web, so that the H-shaped steel web is in a state perpendicular to the positioning clamp 1.

[0040] During use, when the web and flange need to be positioned, first place the web vertically on the ground, hang the flange above the web, and adjust the position so that the flange and web are roughly centered to complete the initial positioning. Then, insert several sets of positioning clips 1 from one end of the web and flange, and at the same time, the flange is located in the first slot 2, and the web is located in the second slot 3. At the same time, the interval between each positioning clip 1 does not exceed 500mm, and tighten the centering bolt 4 until the web and flange are completely centered. After the web and flange are fully aligned, tighten the straightening bolts 5 until the web is completely against the positioning clamp 1. The principle of two points determining a straight line makes the flange and web perpendicular to each other. After the flange and web are aligned and straightened, they are fixed by spot welding. After spot welding is completed, the positioning clamp 1 needs to be removed. At this time, turn the component over and install the flange on the other side of the H-shaped steel in the above order to improve the positioning speed of the web and flange, as well as the centering accuracy of the web and flange.

[0041] In order to facilitate the positioning of flange plates of different specifications and sizes, for example, Figure 3 、 Figure 5 、 Figure 6 As shown, the present invention also includes a storage box 8 for storing the positioning card plate 1, the storage box 8 opens upward, and several groups of positioning card plates 1 are vertically placed in the storage box 8. A positioning groove 9 opening downward is provided on the upper inner side of the first slot 2, and the positioning groove 9 is provided with a driving rod 10. Both ends of the driving rod 10 pass through the positioning card plate 1 and are rotatably connected to the positioning card plate 1. Two groups of mirror-symmetrical threads are provided on the driving rod 10, and the two groups of threads are threadedly connected with a positioning plate 11. The positioning plate 11 is slidably connected to the positioning slot 9, and one end of the driving rod 10 is fixedly connected to the first adjusting knob 12; an adjustment structure for driving all the first adjusting knobs 12 to rotate is provided in the storage box 8.

[0042] When in use, the positioning card plate 1 is inserted from one end of the web plate and the flange plate. At this time, the flange plate is located in the second slot 3. By turning the first adjusting knob 12, the driving rod 10 is driven to rotate. When the driving rod 10 rotates, the two sets of positioning plates 11 are driven by the thread to move closer to each other. When the two sets of positioning plates 11 move to a certain position, they contact with both sides of the flange plate, thereby improving the stability of the flange plate. At the same time, the two sets of positioning plates 11 can be used to facilitate the positioning of flange plates of different specifications and sizes, further improving the convenience of use.

[0043] The storage box 8 is convenient for storing several groups of positioning card plates 1; when several groups of positioning card plates 1 are placed in the storage box 8, the adjustment structure can drive several groups of first adjustment knobs 12 to rotate, and at the same time drive the corresponding two groups of positioning plates 11 to move closer to each other, so that the positions of several groups of positioning plates 11 in the storage box can be adjusted at one time through the adjustment structure according to the specifications of the flange plate, thereby improving the convenience of use and improving the centering efficiency.

[0044] In order to adjust the positions of several groups of positioning plates 11 in the storage box 8 at one time, for example, Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 3 As shown, the present invention further includes that the inner side of the storage box 8 is provided with a plurality of groups of card slots 13 for accommodating the positioning card plate 1;

[0045] The upper surface of the storage box 8 is hinged with a box cover 14 through a hinge. Several groups of rotating shafts 15 distributed in a straight line direction are rotatably connected inside the box cover 14. Support rollers 16 are fixedly connected to the rotating shafts 15. The outer sides of the several groups of support rollers 16 are driven by transmission belts 17. After the box cover 14 is closed, the transmission belt 17 is squeezed and contacted with the upper edge of the first adjusting knob 12. The rotating shaft 15 at one end of the transmission belt 17 passes through the box cover 14 and is fixedly connected to the second adjusting knob 18. Friction pads 19 are provided on the outer sides of the first adjusting knob 12 and the second adjusting knob 18.

[0046] When the second adjusting knob 18 is rotated, the rotating shaft 15 and the supporting roller 16 are driven to rotate. When the supporting roller 16 rotates, the transmission belt 17 is driven to move. When the transmission belt 17 moves, it is pressed and contacted with the plurality of first adjusting knobs 12 and drives the first adjusting knob 12 to rotate. When the first adjusting knob 12 is rotated, the corresponding two groups of positioning plates 11 are driven to move closer to each other, so that the positions of the plurality of positioning plates 11 in the storage box 8 can be adjusted at one time by rotating the second adjusting knob 18 according to the specifications of the flange plate. After the adjustment of the plurality of positioning plates 11 is completed, the box cover 14 is opened and the positioning card 1 is taken out, and the positioning card 1 is inserted into one end of the web plate and the flange plate. The flange plate is located in the first slot 2, and the positioning plate 11 is used to improve the stability of the flange plate, which is convenient for positioning the web plate and the flange plate, further improving the convenience of use and improving the centering efficiency.

[0047] After the positioning card board 1 is used, the positioning card board 1 is placed vertically in the storage box 8, and the positioning card board 1 corresponds to the card slot 13. The card slot 13 is used to improve the stability of the positioning card board 1, so as to facilitate the storage of the positioning card board 1 after use;

[0048] After the positioning card plate 1 is placed in the storage box 8, the transmission belt 17 can be driven to move by driving the second adjusting knob 18 to rotate, thereby driving the driving rod 10 to rotate and moving the positioning plate 11 to the two ends of the driving rod 10; after the positioning plate 11 moves to the two ends of the driving rod 10, the second adjusting knob 18 can be further rotated. Since the corresponding positioning plate 11 has moved to the extreme position, the first adjusting knob 12 cannot be driven by the transmission belt 17 at this time, and the first adjusting knob 12 and the transmission belt 17 move relative to each other. At this time, rotating the second adjusting knob 18 to a certain angle can ensure that all the positioning plates 11 are driven to the two ends of the driving rod 10, so that all the positioning plates 11 can be moved to the appropriate position by rotating the second adjusting knob 18 later.

[0049] In order to facilitate the rapid disassembly of the centering bolt 4 and the straightening bolt 5, for example, Figure 2 、 Figure 3 、 Figure 4 As shown, the present invention provides two groups of nuts 6 threadedly connected to the centering bolt 4 and the straightening bolt 5. The centering bolt 4 and the straightening bolt 5 are each sleeved with a torsion assembly for driving the centering bolt 4 and the straightening bolt 5 to rotate and reset. There are two torsion assemblies, one of which is provided between each group of nuts 6. The torsion assembly includes a sleeve 20 and ratchet teeth 21 distributed circumferentially on the outside of the sleeve 20. The centering bolt 4 and the straightening bolt 5 are respectively fixedly connected to the sleeve 20.

[0050] A first torsion spring 22 is connected between the centering bolt 4 and the nut 6, as well as between the straightening bolt 5 and the nut 6. An inclined pawl 23 is provided above the centering bolt 4 and the straightening bolt 5. The end of the pawl 23 close to the ratchet 21 is initially engaged with one side of the ratchet 21. The other end of the pawl 23 is hinged to the positioning card plate 1 through a second torsion spring 24. A lever 25 is fixedly connected above the end of the pawl 23 away from the positioning card plate 1.

[0051] A rotating structure is provided on the outside of the storage box 8 to drive the centering bolt 4 and the straightening bolt 5 to rotate.

[0052] When in use, the positioning card plate 1 is inserted from one end of the web and the flange plate, the flange plate is located in the first slot 2, and the web plate is located in the second slot 3. Then the centering bolt 4 and the straightening bolt 5 are rotated. When the centering bolt 4 and the straightening bolt 5 are rotated, they are threadedly connected with the nut 6, and at the same time drive the first torsion spring 22 to store force. When the centering bolt 4 and the straightening bolt 5 are rotated, the sleeve 20 and the ratchet 21 are driven to rotate and move. When the ratchet 21 rotates, the pawl 23 is engaged with one side of the ratchet 21, thereby fixing the ratchet 21 to ensure the stability of the sleeve 20. When the centering bolt 4 and the straightening bolt 5 are rotated to a certain position, one end of the centering bolt 4 and the straightening bolt 5 is squeezed and contacted with one side of the web plate, and the web plate is adjusted by relying on the centering bolt 4 and the straightening bolt 5, so as to quickly align the web and the flange plate.

[0053] When the web and flange plates are spot-welded, if the positioning clamping plate 1 needs to be disassembled, the pawl 23 is moved upward by pushing the lever 25 upward. When the pawl 23 moves upward, the pawl 23 no longer engages one side of the ratchet tooth 21. At this time, the centering bolt 4 and the straightening bolt 5 are driven to return to their original position and rotate by relying on the reset effect of the first torsion spring 22. When the centering bolt 4 and the straightening bolt 5 rotate, they no longer squeeze the outer side of the web, thereby facilitating the rapid disassembly of the centering bolt 4 and the straightening bolt 5, thereby improving the disassembly efficiency and convenience of use.

[0054] When the first torsion spring 22 is reset to its initial state, the lever 25 is no longer lifted, and the pawl 23 is reset and moved downward by the action of the second torsion spring 24. At the same time, the pawl 23 is again engaged with one side of the ratchet tooth 21, thereby restoring the pawl 23 to its initial state, thereby improving the convenience of subsequent use.

[0055] In order to improve the convenience and efficiency of positioning the centering bolt 4 and the web, for example, Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11As shown, the present invention also includes a rotating structure including a shell 26 detachably connected to one side of the storage box 8, a plurality of groups of horizontally distributed first rotating tubes 27 are provided in the shell 26, one end of the first rotating tube 27 passes through the storage box 8 and is rotatably connected to the storage box 8, a horizontally arranged first rotating rod 28 is slidably connected in each of the first rotating tubes 27, and a first magnet is provided at one end of the first rotating rod 28 close to the centering bolt 4, and the first magnet is magnetically attracted to one side of the centering bolt 4;

[0056] One end of the first rotating tube 27 located inside the storage box 8 is fixedly connected to the first rotating rod 28 through a first spring 29. The outside of the first rotating tube 27 has teeth. A horizontally arranged first transmission rod 30 is provided below the first rotating tube 27. The first transmission rod 30 is fixedly connected with several groups of first vortex teeth 31 for engaging with the teeth on the first rotating tube 27; several groups of first fixed blocks 32 are rotatably connected to the first transmission rod 30, and the first fixed block 32 is fixedly connected to the outside of the storage box 8. One end of the first transmission rod 30 passes through the shell 26 and is fixedly connected to a crank 33. The first transmission rod 30 is rotatably connected to the shell 26.

[0057] When in use, when several groups of positioning card plates 1 are located in the card slots 13 in the storage box 8, one end of the first rotating rod 28 is magnetically attracted to one side of the centering bolt 4, and the first transmission rod 30 and the first vortex gear 31 are driven to rotate by turning the crank 33. When the first vortex gear 31 rotates, it engages with the tooth structure on the outer side of the first rotating tube 27 for transmission, and drives the first rotating tube 27 to rotate. When the first rotating tube 27 rotates, it drives the first rotating rod 28 to rotate. When the first rotating rod 28 rotates, it drives the centering bolt 4 to rotate, so that the centering bolt 4 moves. When the centering bolt 4 moves, it relies on magnetic attraction to drive the first rotating rod 28 to slide in the first rotating tube 27, and at the same time drives the first spring 29 to store force, so that the positions of several groups of centering bolts 4 in the storage box 8 can be roughly adjusted at one time according to the thickness of the web, thereby improving the convenience and efficiency of subsequent positioning of the centering bolt 4 and the web;

[0058] After the positioning card plate 1 is taken out of the storage box 8, the first rotating rod 28 is driven to return to its initial state by the action of the first spring 29, so that when the positioning card plate 1 is placed in the storage box 8 again, the first rotating rod 28 is magnetically attracted to one side of the centering bolt 4 again;

[0059] The first fixing block 32 can improve the overall stability of the first transmission rod 30;

[0060] It should be pointed out that after the adjustment of the centering bolt 4 of the present invention is completed, the positioning clamp 1 is taken out and inserted into one end of the web and flange plate, and then the centering bolt 4 needs to be rotated according to the size of the web for precise adjustment, so as to improve the extrusion accuracy of the centering bolt 4 and one side of the web.

[0061] In order to improve the convenience and efficiency of positioning the straightening bolt 5 and the web, for example, Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 As shown, the present invention further includes a plurality of horizontally distributed second rotating tubes 34 provided in the housing 26. The second rotating tubes 34 are located below the first rotating tubes 27. One end of the second rotating tubes 34 passes through the storage box 8 and is rotatably connected to the storage box 8. A horizontally arranged second rotating rod 35 is slidably connected in each of the second rotating tubes 34. A second magnet is provided at one end of the second rotating rod 35 near the straightening bolt 5. The second magnet is magnetically attracted to one side of the straightening bolt 5.

[0062] One end of the second rotating tube 34 located inside the storage box 8 is fixedly connected to the second rotating rod 35 via a second spring 36. The outer side of the second rotating tube 34 has teeth. A horizontally arranged second transmission rod 37 is provided below the second rotating tube 34. The second transmission rod 37 is fixedly connected to a plurality of groups of second vortex teeth 38 that mesh with the teeth on the second rotating tube 34. The second transmission rod 37 is rotatably connected to a plurality of groups of second fixed blocks 39. The second fixed blocks 39 are fixedly connected to the outer side of the storage box 8.

[0063] One end of the first transmission rod 30 is fixedly connected to a first pulley 40 , and one end of the second transmission rod 37 is fixedly connected to a second pulley 41 . The first pulley 40 and the second pulley 41 are driven by a transmission belt 46 .

[0064] When the second rotating tube 34 is rotated, the second rotating rod 35 is driven by the second spring 36 to store force, thereby facilitating the adjustment of the plurality of straightening bolts 5 in the storage box 8.

[0065] After the positioning card plate 1 is taken out of the storage box 8, the second rotating rod 35 is driven to return to its initial state by the action of the second spring 36, so that when the positioning card plate 1 is placed in the storage box 8 again, the second rotating rod 35 is magnetically attracted to one side of the straightening bolt 5 again;

[0066] The overall stability of the second transmission rod 37 can be improved by relying on the second fixing block 39;

[0067] It should be pointed out that after the straightening bolt 5 of the present invention is adjusted, the positioning clamp 1 is taken out and inserted into one end of the web and flange plate, and then the straightening bolt 5 needs to be rotated according to the size of the web for precise adjustment, so as to improve the extrusion accuracy between the straightening bolt 5 and one side of the web.

[0068] For example, Figure 8 、 Figure 9 As shown, the present invention also includes that the first rotating rod 28 and the second rotating rod 35 are both polygonal rods, and the inner sides of the first rotating tube 27 and the second rotating tube 34 are both provided with polygonal through holes 42 that match the shape of the polygonal rods.

[0069] During use, the first rotating rod 28 and the second rotating rod 35 are polygonal rods, which can prevent the first rotating rod 28 and the first rotating tube 27 from rotating relative to each other, and prevent the second rotating rod 35 and the second rotating tube 34 from rotating relative to each other.

[0070] For example, Figure 5 As shown, the present invention further includes that both sides of the storage box 8 are provided with a lifting handle 43; and one side of the box cover 14 is provided with an anti-slip handle 44.

[0071] When in use, the storage box 8 can be easily moved by pulling the handle 43 , and the box cover 14 can be easily opened by the anti-slip handle 44 .

[0072] For example, Figure 2 As shown, the present invention also includes that wedge-shaped stiffening plates 45 are provided on both sides of the positioning clamping plate 1 , and the stiffening plates 45 are located above the first slot 2 .

[0073] During use, when the flange plate is located in the first slot 2 , the stiffening plate 45 can further improve the stability of one side of the flange plate.

[0074] Exemplarily, the present invention further includes that a mechanical lock is provided between the box cover 14 and the storage box 8 .

[0075] During use, after several sets of positioning card plates 1 are used and placed in the storage box 8, the box cover 14 and the storage box 8 are locked by a mechanical lock to ensure the stability between the box cover 14 and the storage box 8. At the same time, it is convenient to rotate the second adjustment knob 18 according to the specifications of the flange plate, and drive several sets of first adjustment knobs 12 to rotate through the transmission belt 17 to ensure the extrusion contact effect between the transmission belt 17 and the outer side of the first adjustment knob 12.

[0076] When the first embodiment of the present invention is used, when it is necessary to position the web and the flange, first place the web vertically on the ground, hang the flange above the web, and adjust the position so that the flange and the web are roughly centered to complete the initial positioning. Then, insert several sets of positioning clamps 1 from one end of the web and the flange, and at the same time, the flange is located in the first slot 2, the web is located in the second slot 3, and the interval between each positioning clamp 1 does not exceed 500mm. Screw the centering bolt 4 until the web and the flange are aligned. After the flange plate is completely aligned and the web plate and flange plate are completely aligned, the straightening bolts 5 are tightened until the web plate is completely against the positioning clamp 1. The principle of two points determining a straight line is used to make the flange plate and the web plate perpendicular to each other. After the flange plate and the web plate are aligned and straightened, they are fixed by spot welding. After the spot welding is completed, the positioning clamp 1 is removed, the component is turned over, and the flange plate on the other side of the H-shaped steel is installed in the above order to improve the positioning speed of the web plate and the flange plate, as well as the centering accuracy of the web plate and the flange plate.

[0077] When the second embodiment of the present invention is in use, when a centering operation is required, the storage box 8 is moved to the construction site, and the second adjusting knob 18 on the outside of the box cover 14 is rotated according to the specifications of the flange plate. When the second adjusting knob 18 is rotated, the rotating shaft 15 and the support roller 16 are driven to rotate. When the support roller 16 is rotated, the transmission belt 17 is driven to move. When the transmission belt 17 moves, it is pressed and contacted with several groups of first adjusting knobs 12 and drives the first adjusting knobs 12 to rotate. When the first adjusting knob 12 is rotated, the corresponding two groups of positioning plates 11 are driven to move closer. This makes it easy to adjust the positions of several groups of positioning plates 11 in the storage box 8 at one time by rotating the second adjusting knob 18 according to the specifications of the flange plate.

[0078] Then, the first transmission rod 30 and the first volute 31 are driven to rotate by rotating the crank handle 33. When the first volute 31 rotates, it engages with the tooth structure on the outer side of the first rotating tube 27 for transmission, and drives the first rotating tube 27 to rotate. When the first rotating tube 27 rotates, it drives the first rotating rod 28 to rotate. When the first rotating rod 28 rotates, it drives the centering bolt 4 to rotate, so that the centering bolt 4 moves. When the centering bolt 4 moves, it relies on magnetic adsorption to drive the first rotating rod 28 to slide in the first rotating tube 27, and at the same time drives the first spring 29 to store force, so that the positions of several groups of centering bolts 4 in the storage box 8 can be roughly adjusted at one time according to the thickness of the web, thereby improving the convenience and efficiency of subsequent positioning of the centering bolt 4 and the web.

[0079] When the first transmission rod 30 rotates, it relies on the first pulley 40, the transmission belt 46 and the second pulley 41 to drive the second transmission rod 37 to rotate. When the second transmission rod 37 rotates, it drives the second vortex 38 to rotate. When the second vortex 38 rotates, it engages with the tooth structure on the outer side of the second rotating tube 34 for transmission, and drives the second rotating tube 34 to rotate. When the second rotating tube 34 rotates, it drives the second rotating rod 35 to rotate. When the second rotating rod 35 rotates, it drives the straightening bolt 5 to rotate, so that the straightening bolt 5 moves. When the straightening bolt 5 moves, it relies on magnetic adsorption to drive the second rotating rod 35 to slide in the second rotating tube 34, and at the same time drives the second spring 36 to store force, so that it is convenient to roughly adjust the positions of several groups of straightening bolts 5 in the storage box 8 at one time according to the thickness of the web, thereby improving the convenience and efficiency of subsequent positioning of the straightening bolts 5 and the web;

[0080] When the positions of the centering bolts 4 and the straightening bolts 5 are roughly adjusted, open the box cover 14 to take out the positioning card plate 1, and insert the positioning card plate 1 from one end of the web and the flange plate. The flange plate is located in the first slot 2, and the web plate is located in the second slot 3. The stability of the flange plate is improved by relying on the positioning plate 11, which is convenient for positioning the web and the flange plate. At the same time, the centering bolts 4 and the straightening bolts 5 are rotated to accurately adjust the centering bolts 4 and the straightening bolts 5. When the centering bolts 4 and the straightening bolts 5 are rotated, they are threadedly connected with the nuts 6, and at the same time, The first torsion spring 22 is activated to store force. When the centering bolt 4 and the straightening bolt 5 rotate, the sleeve 20 and the ratchet 21 are driven to rotate and move. When the ratchet 21 rotates, the pawl 23 engages with one side of the ratchet 21, thereby fixing the ratchet 21 and ensuring the stability of the sleeve 20. When the centering bolt 4 and the straightening bolt 5 rotate to a certain position, one end of the centering bolt 4 and the straightening bolt 5 is pressed into contact with one side of the web. The web is adjusted by the centering bolt 4 and the straightening bolt 5, thereby quickly centering the web and the flange plate.

[0081] After the flange plate and the web plate are aligned and straightened, they are fixed by spot welding. After the spot welding is completed, when the positioning clamping plate 1 needs to be disassembled, the pawl 23 is driven upward by toggling the toggle lever 25. When the pawl 23 moves upward, the pawl 23 no longer engages with one side of the ratchet tooth 21. At this time, the centering bolt 4 and the straightening bolt 5 are driven to return and rotate by relying on the reset effect of the first torsion spring 22. When the centering bolt 4 and the straightening bolt 5 are rotated, they no longer squeeze the outer side of the web plate, thereby facilitating the rapid disassembly of the centering bolt 4 and the straightening bolt 5, thereby improving the disassembly efficiency and convenience of use.

[0082] After the positioning card board 1 is used, the positioning card board 1 is placed vertically in the storage box 8, and the positioning card board 1 corresponds to the card slot 13. The card slot 13 is used to improve the stability of the positioning card board 1, so as to facilitate the storage of the positioning card board 1 after use;

[0083] After the positioning card plate 1 is placed in the storage box 8, the transmission belt 17 can be driven to move by driving the second adjusting knob 18 to rotate, thereby driving the driving rod 10 to rotate and moving the positioning plate 11 to the two ends of the driving rod 10; after the positioning plate 11 moves to the two ends of the driving rod 10, the second adjusting knob 18 can be further rotated. Since the corresponding positioning plate 11 has moved to the extreme position, the first adjusting knob 12 cannot be driven by the transmission belt 17 at this time, and the first adjusting knob 12 and the transmission belt 17 move relative to each other. At this time, rotating the second adjusting knob 18 to a certain angle can ensure that all the positioning plates 11 are driven to the two ends of the driving rod 10, so that all the positioning plates 11 can be moved to the appropriate position by rotating the second adjusting knob 18 later.

Those skilled in the art should understand that the present invention is not limited to the above-described embodiments.
