DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1-10 As shown, a positioning welding device for processing H-shaped steel columns, such as Figure 1-3 and Figure 5 As shown, it includes a mounting frame 1; a mounting seat 2 is arranged on the mounting frame 1, and a positioning mechanism 4, a pressure regulating mechanism 5 and a welding mechanism 6 are arranged on the mounting seat 2; the positioning mechanism 4 is used to position and clamp the liner; the pressure regulating mechanism 5 is used to adjust the pressure between the H-shaped steel and the liner; the welding mechanism 6 is used to move along the weld between the H-shaped steel and the liner to perform rotational welding.

[0039] It should be noted that the lining plate is positioned and fixed by the positioning mechanism 4, and then the H-shaped steel is restricted on the mounting seat 2, so that the H-shaped steel and the lining plate are aligned and fixed, and then the top of the weld position between the H-shaped steel and the lining plate is first welded by the welding mechanism 6. During the welding process, as the welding temperature increases, the H-shaped steel and the lining plate will be deformed. At this time, the H-shaped steel and the lining plate are driven to rotate by the pressure regulating mechanism 5, so that the lining plate is under the H-shaped steel. The pressure between the H-shaped steel and the lining plate is increased by the weight of the H-shaped steel to prevent deformation between the H-shaped steel and the lining plate during welding, thereby ensuring the welding quality.

[0040] like Figure 1-2 Figure 4 and Figure 8As shown, the positioning mechanism 4 includes a positioning plate 41, a positioning block 42 and a plurality of positioning pins 43; the positioning plate 41 is arranged on the mounting seat 2, the positioning block 42 is arranged on the positioning plate 41, the positioning block 42 is in conflict with the lining plate, a plurality of positioning pins 43 are arranged on the positioning plate 41, and the positioning pins 43 are a stepped shaft structure, and the thin shaft of the stepped shaft is adaptively plugged into the mounting hole of the lining plate.

[0041] It should be noted that when positioning the liner, the liner is plugged into the locating pin 43 so that the locating pin 43 is plugged into the mounting hole on the liner. At this time, the thin shaft of the locating pin 43 is plugged into the mounting hole of the liner, and the thick shaft of the locating pin 43 is in contact with the liner. The thin shaft is relative to the thick shaft, that is, the diameter of the thin shaft is smaller than the diameter of the thick shaft; and at this time, the positioning block 42 just contacts with the liner, and the liner is positioned and supported by the cooperation of the locating pin 43 and the positioning block 42, and then the H-shaped steel is driven to align and contact with the liner to achieve the positioning work before welding; the positioning work of the liner is achieved through the mounting hole structure provided on the liner, and the lining is contacted by the locating pin 43 and the positioning block 42 to reduce the contact between the positioning plate 41 and the liner, thereby reducing heat transfer, reducing the influence of high temperature on the positioning mechanism 4 during welding, and preventing the positioning mechanism 4 from overheating and deformation; it can be understood that the heat resistance of the positioning mechanism 4 is stronger than that of the H-shaped steel and the liner. For example, the material of the positioning mechanism 4 can be titanium alloy.

[0042] like Figure 1-2 and Figure 4-5 As shown, the pressure regulating mechanism 5 includes a pressure sensing mechanism 51 and a second hydraulic cylinder 52; the pressure sensing mechanism 51 is arranged between the mounting seat 2 and the positioning plate 41; the pressure sensing mechanism 51 is used to detect the pressure exerted on the positioning plate 41; the second hydraulic cylinder 52 is installed between the mounting frame 1 and the mounting seat 2, and the mounting seat 2 is hinged to the mounting frame 1; the second hydraulic cylinder 52 is used to drive the mounting seat 2 to rotate, so as to drive the H-shaped steel and the lining plate to rotate synchronously; a counterweight block 53 is arranged on the mounting frame 1 at a position away from the positioning mechanism 4; the counterweight block 53 is used to adjust the overall center of gravity of the positioning welding device.

[0043] It should be noted that, during the welding process of the H-beam column, when the high temperature causes the H-beam or the lining to deform, the pressure between the H-beam and the lining increases due to thermal expansion. When the pressure sensing mechanism 51 detects the increase in pressure between the H-beam and the lining, the second hydraulic cylinder 52 drives the mounting seat 2 to rotate, thereby driving the H-beam and the lining to rotate, so that the H-beam is above the lining. Through the high weight characteristics of the H-beam, the pressure between the H-beam and the lining is increased to prevent the deformation between the H-beam and the lining caused by the high temperature during welding; the second hydraulic cylinder 52 is controlled to push the H-beam to rotate upward to adjust the pressure between the H-beam and the lining, thereby improving the anti-deformation effect.

[0044] like Figure 7-8As shown, the pressure sensing mechanism 51 includes a heat insulation plate 511 and a pressure sensor 512; the positioning plate 41 is slidably connected to the mounting seat 2, the heat insulation plate 511 is arranged on the positioning plate 41, and the pressure sensor 512 is arranged between the heat insulation plate 511 and the mounting seat 2; the pressure sensor 512 is used to detect the pressure between the heat insulation plate 511 and the mounting seat 2.

[0045] It should be noted that when welding causes the H-beam or the liner to deform, so that the pressure between the H-beam and the liner increases, the pressure increase is detected by the pressure sensor 512 at this time, and a controller is also installed on the mounting frame 1, and the second hydraulic cylinder 52 and the pressure sensor 512 are both connected to the controller through electrical signal control; it can be understood that the controller is a prior art, which is not drawn in the figure and will not be described in detail; when the pressure sensor 512 detects that the pressure increases, the second hydraulic cylinder 52 is controlled by the controller to start, thereby driving the H-beam and the liner to rotate, so as to achieve the purpose of adjusting the pressure between the H-beam and the liner;

[0046] By setting the heat insulation plate 511, the heat transfer to the pressure sensor 512 is reduced, ensuring the effective operation of the pressure sensor 512; and the positioning block 42 is an H-shaped structure slightly larger than the cross-section of the H-shaped steel, which ensures effective support for the liner while reducing the contact between the positioning block 42 and the liner, further reducing the heat transfer; to further reduce the influence of heat on the pressure sensor 512, a heat insulation structure, such as a ceramic heat insulation layer, can be wrapped around the outside of the pressure sensor 512; it can be understood that the pressure sensor 512 is a prior art and will not be described in detail.

[0047] like Figure 1-2 and Figure 9-10 As shown, the welding mechanism 6 includes a rotating mechanism 61, a positioning adjustment mechanism 62 and a welder 63; the rotating mechanism 61 is arranged on the mounting seat 2, and the rotating mechanism 61 is used to drive the welder 63 to rotate along the circumferential direction of the H-shaped steel; the positioning adjustment mechanism 62 is arranged on the rotating mechanism 61, and the positioning adjustment mechanism 62 is used to adjust the distance and angle between the welder 63 and the weld between the H-shaped steel and the lining plate; the welder 63 is arranged on the positioning adjustment mechanism 62, and the welder 63 is used to weld the H-shaped steel and the lining plate.

[0048] It should be noted that during welding, the welder 63 is driven to rotate along the circumference of the H-beam by the rotating mechanism 61, and the position and angle of the welder 63 are controlled by the positioning adjustment mechanism 62, so that the welder 63 is always close to the weld between the H-beam and the lining plate, thereby achieving precise welding. As the H-beam and the lining plate are deformed during welding, the H-beam is driven to rotate by the pressure adjustment mechanism 5, which drives the welder 63 to rotate. During the welding process, the welding temperature continues to increase, which drives the welder 63 to rotate upward continuously. When the welder 63 rotates along the circumference of the H-beam for welding, the welder 63 can still always be above the welding point, and overhead welding will not be performed, which will not cause the welding molten material to drip onto the welding equipment. This can reduce the dripping of the molten material and ensure the welding quality.

[0049] like Figure 1-2 and Figure 9-10 As shown, it can be understood that the present application does not limit the specific structure and installation method of the rotating mechanism 61, and only a feasible technical solution is provided below; the rotating mechanism 61 includes a second motor 611, a gear set 612, a second driven gear 613, a mounting ring 614 and an outer gear ring 615; the second motor 611 is installed on the mounting seat 2, the gear set 612 is arranged between the second motor 611 and the second driven gear 613, the second motor 611 can drive the second driven gear 613 to rotate through the gear set 612, the mounting ring 614 is arranged on the mounting seat 2, and when the H-shaped steel is welded to the liner, the mounting ring 614 is sleeved on the H-shaped steel, and the outer gear ring 615 is coaxially rotatably connected to the mounting ring 614; the positioning adjustment mechanism 62 is arranged on the outer gear ring 615; the mounting ring 614 and the outer gear ring 615 are both provided with openings 616; when the openings 616 on the mounting ring 614 and the outer gear ring 615 overlap, the H-shaped steel shell moves out of the opening 616.

[0050] It should be noted that the second motor 611 drives the gear set 612 to move. The gear set 612 is a prior art. The gear set 612 includes two mutually meshing spur gears. The gear set 612 drives the second driven gear 613 to rotate, and the second driven gear 613 drives the outer gear ring 615 to rotate, thereby driving the positioning adjustment mechanism 62 on the outer gear ring 615 to rotate, thereby driving the welder 63 to rotate along the circumference of the H-shaped steel, thereby realizing the welding work of the entire weld.

[0051] After the welding work is completed, the second motor 611 can be used to drive the outer gear ring 615 to overlap with the opening 616 on the mounting ring 614, so that the H-shaped steel can be taken out from the opening 616; it can be understood that at this time, in order to ensure that the outer gear ring 615 can rotate continuously (such as Fig.10As shown in the figure, at least two sets of second motors 611, gear sets 612 and second driven gears 613 need to be provided so that the setting of the opening portion 616 does not affect the normal rotation of the driving outer gear ring 615.

[0052] like Figure 1-2 and Figure 9-10 As shown, it can be understood that the present application does not limit the specific structure and installation method of the positioning adjustment mechanism 62, and only a feasible technical solution is provided below; the positioning adjustment mechanism 62 includes a linear module 621, a rotary cylinder 622 and a third motor 623; the linear module 621 is arranged on the outer gear ring 615, the rotary cylinder 622 is arranged at the output end of the linear module 621, the third motor 623 is arranged at the output end of the rotary cylinder 622, and the welder 63 is installed at the output end of the third motor 623.

[0053] It should be noted that in the process of the rotating mechanism 61 driving the positioning adjustment mechanism 62 to rotate, the linear module 621 drives the welder 63 to approach or move away from the weld, and the rotating cylinder 622 and the third motor 623 drive the welder 63 to rotate, so as to control the angle between the welder 63 and the weld and achieve the purpose of precise control; it should be noted that the linear module 621, the rotating cylinder 622 and the third motor 623 are all connected to the controller through electrical signal control, and the controller can be a PLC control system, which can realize precise control of the movement of the welder 63 according to different types of H-shaped steel structures to ensure the welding quality.

[0054] like Figure 1-2 , Figure 4 and Figure 6 As shown, a limiting mechanism 3 for positioning and clamping the H-beam is provided on the mounting seat 2; the limiting mechanism 3 includes a clamping mechanism 32, a driving mechanism 33 and two sets of positioning wheels 31; the two sets of positioning wheels 31 are provided on the mounting seat 2, and the two sets of positioning wheels 31 are respectively provided on the opposite sides of the H-beam; the clamping mechanism 32 and the driving mechanism 33 are both provided on the mounting seat 2, and the clamping mechanism 32 is used to drive the two sets of positioning wheels 31 to approach the H-beam to clamp the H-beam; the driving mechanism 33 is used to drive the positioning wheel 31 to rotate to push the H-beam to move along its axial direction, thereby keeping the end of the H-beam in contact with the liner.

[0055] It should be noted that when positioning and clamping the H-beam, the H-beam is first placed between the two sets of positioning wheels 31 by means of lifting equipment, and then the two sets of positioning wheels 31 are driven close to each other by the clamping mechanism 32 to position and clamp the web of the H-beam; then the positioning wheels 31 are driven to rotate by the driving mechanism 33, thereby pushing the H-beam to approach and contact the lining plate, thereby achieving the positioning and fixing of the H-beam and the lining plate; during the welding process, the pressure regulating mechanism 5 drives the H-beam to rotate upward and the driving mechanism 33 drives the H-beam to continue to approach the lining plate. These two actions can be performed simultaneously, thereby achieving the purpose of quickly increasing the pressure between the H-beam and the lining plate, thereby further improving the anti-deformation effect.

[0056] like Figure 1-2 , Figure 4 and Figure 6 As shown, it can be understood that the present application does not limit the specific structure and use of the clamping mechanism 32. The following only provides a feasible technical solution; the clamping mechanism 32 includes a connecting rod 321, a first hydraulic cylinder 326, two sets of rotating frames 324 and a rotating block 325 and a plurality of connecting blocks 322; the connecting rod 321 is slidably connected to the mounting seat 2, a plurality of connecting blocks 322 are arranged on the connecting rod 321, the two sets of rotating frames 324 are respectively rotatably connected to the two sides of the H-shaped steel, and the positioning wheel 31 rotates It is connected to the rotating frame 324, the axis of the positioning wheel 31 is parallel to the rotating axis of the rotating frame 324, and the axis of the positioning wheel 31 is perpendicular to the wing plate of the H-shaped steel; the rotating block 325 is arranged on the rotating frame 324, and a slider is arranged on the rotating block 325, a sliding groove 323 is opened on the connecting block 322, and the slider is slidably connected to the sliding groove 323; the first hydraulic cylinder 326 is arranged between the mounting seat 2 and the connecting rod 321, and the first hydraulic cylinder 326 is used to drive the connecting rod 321 to slide along the axial direction of the H-shaped steel.

[0057] It should be noted that the first hydraulic cylinder 326 pushes the connecting rod 321 to move, thereby driving the connecting block 322 to move. Through the cooperation of the slide groove 323 and the slider, the rotating block 325 is pushed to rotate, thereby driving the rotating frame 324 to rotate, and the rotating frame 324 drives the positioning wheel 31 to rotate. It can be understood that the axis of the positioning wheel 31 does not coincide with the axis of the rotating frame 324, that is, when the rotating frame 324 rotates, it can drive the positioning wheel 31 to move closer to or farther away from the H-shaped steel, thereby realizing the clamping work of the H-shaped steel.

[0058] like Figure 1-2 , Figure 4 and Figure 6As shown, it can be understood that the present application does not limit the specific structure and installation method of the driving mechanism 33, and only a feasible technical solution is provided below; the driving mechanism 33 includes a first motor 331, a driving gear 332 and a first driven gear 333; the first motor 331 is installed on the rotating frame 324, the driving gear 332 is coaxially connected to the output end of the first motor 331, the first driven gear 333 is coaxially connected to the positioning wheel 31, and the driving gear 332 is meshed with the first driven gear 333.

[0059] It should be noted that the first motor 331 drives the driving gear 332 to rotate, and the driving gear 332 drives the first driven gear 333 to rotate, so that the first driven gear 333 drives the positioning wheel 31 to rotate, thereby driving the positioning wheel 31 to rotate along its axis, and then through the cooperation of the two sets of positioning wheels 31, the H-shaped steel is pushed to move and contact and align with the liner.
