Description

Technical Field

[0001] The invention relates to the technical field of welding devices, and in particular to a steel structure processing welding device and process. Background Art

[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. It is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates. These components are usually connected by welds, bolts or rivets. Lattice columns are a special form of steel structure columns (such as Fig. 9 As shown), it is composed of four angle steels arranged in a square shape, and multiple groups of steel plates for improving the overall strength of the lattice column are equidistantly welded on the outer end faces of the four angle steels, and each group of steel plates is equidistantly arranged on the outer end faces of the angle steels in the circumferential direction.

[0003] During the welding process of the existing lattice column, the four angle steels placed at the predetermined position need to be clamped and fixed by fastening clamps. Then the staff will place the steel plate close to the outer wall of the angle steel and weld the steel plate to the outer end face of the angle steel through welding equipment (including welding guns, fixing clamps, motors and other related equipment). During welding, it is necessary to ensure that the central axis of each steel plate is consistent with the central axis of the corresponding two angle steels, so that the lattice column has good overall stability and excellent bending resistance.

[0004] The existing lattice columns have the following problems and defects when welding: 1. The workers need to place the steel plates tightly against the outside of the clamped angle steel and weld them. However, the steel plates on the left and right sides of the angle steel are easily affected by gravity and downward displacement and manual operation errors during welding, making it impossible for the welded steel plates to be consistent with the central axis of the corresponding two angle steels, resulting in the displacement of the center of gravity of the welded lattice column, which reduces the external load, reduces its bending resistance, and reduces product quality; 2. When welding the existing lattice columns, it is necessary to first fit the connecting steel plates on the left and right sides to the outer wall of the angle steel for welding, and then flip the entire angle steel structure to weld the remaining two sides. It is impossible to clamp and fix the four connecting steel plates on the outer wall of the angle steel for welding at the same time, which not only prolongs the time required for welding and reduces work efficiency, but also easily causes the position of the connecting steel plates to shift during the flipping process, resulting in the problem of inclination between the welded angle steel and the steel plate due to deviation or misalignment of the weld position, which reduces the welding quality. Summary of the invention

[0005] Based on this, it is necessary to provide a steel structure processing welding device and process, which aims to solve the problem that when welding lattice columns in the prior art, the center axis of the steel plate is easily inconsistent with the center axis of the corresponding two angle steels due to gravity factors or manual errors, thereby reducing the overall stability of the lattice column and the product quality.

[0017] In addition, the present invention also provides a steel structure processing welding process, comprising the following steps:

[0018] S1. Clamping angle steel: The operator places four angle steels on the corresponding clamping components, and then the external motor drives the drive unit 1 to operate, so that the drive unit 1 drives the two first rack plates to move toward each other on the diagonal of the fixed box, so that the clamping component clamps the corresponding angle steel at the diagonal of the fixed box, ensuring that the four angle steels are distributed in a square, which is convenient for aligning and welding the steel plate with the corresponding two angle steels.

[0019] S2. Alignment of steel plate and angle steel: The external cylinder drives the limit plate and the push plate to slide to the left, so that the four support plates slide upward synchronously along the inclined surface of the push plate. The support plate drives the rectangular block to move synchronously until the rectangular block contacts the inner right-angle end face of the angle steel and the roller can cooperate with the electric slider to move to the specified welding position. During welding, the support plate and the rectangular block are used to provide fixed support on the inner right-angle end face of the corresponding angle steel to prevent the angle steel from shifting due to uneven force on the angle steel.

[0020] After the mobile box moves to the designated welding position, the staff rotates the reciprocating screws on both sides of the mobile box until the height of the two placement plates is the same as the height of the corresponding two angle steels. By moving the convergence plate and cooperating with the centering unit, the steel plates and angle steels on the upper and lower sides and the left and right sides of the angle steel are aligned in the center to avoid tilting between the steel plates and the angle steels.

[0021] The external cylinder drives the limit plate to slide to the left, so that the limit plate drives the drive unit 2 to operate, and the drive unit 2 drives the corresponding lower pressure plate to move closer to the moving box, and the lower pressure plate drives the tightening bar to move synchronously, so that the tightening bar drives the centrally aligned steel plate to move synchronously, and multiple tightening bars drive the corresponding steel plates to move synchronously, so that multiple steel plates are synchronously tightly attached to and centrally aligned with the outer walls of the two corresponding angle steels, ensuring that multiple steel plates can be centrally welded between the two corresponding angle steels, which is beneficial to improving the strength of the lattice column, reducing the time required for welding positioning, and improving work efficiency.

[0022] In summary, the present invention includes at least one of the following beneficial effects: First, the four angle steels placed on the clamping assembly are clamped and fixed by the operation of the driving unit, and then the limit plate drives the corresponding tightening strip to move toward the angle steel, so that the four center-aligned steel plates are synchronously pressed against the angle steel, so that the staff can weld and fix the steel plates at four angles at the same time, reducing the time required for welding and fixing, and improving work efficiency; secondly, the steel plates on the left and right sides of the angle steel are supported by the centering unit during welding, and the steel plates are guided to fit in the center with the corresponding two angle steels to prevent tilting between the steel plates and the angle steels.

[0023] Second, the staff placed the four angle steels on the clamping components at the four corners of the fixed box, and then drove the clamping blocks through the rotating rod to clamp and fix the corresponding inner and outer right-angle end faces of the angle steels, so that the four angle steels remain stable during welding, which helps to improve the accuracy and quality of welding. Secondly, the clamping mechanism can arrange the four angle steels in a square to ensure the stability and bearing capacity of the overall structure.

[0024] 3. When welding steel plates, support plates are used to synchronously support the corresponding right-angle end faces of the angle steels to prevent the angle steels from shifting due to uneven force during welding, causing the angle steels and steel plates to tilt and lead to deviations in the weld position. This further improves the stability and quality of the angle steels during welding.

[0025] Fourth, the limit plate is driven by the driving unit 2 to cooperate with the distance unit and the centering unit to keep the central axis of the steel plate aligned with the central axis of the corresponding two angle steels, and ensure that multiple steel plates can be centrally welded between the two corresponding angle steels. This not only improves the strength of the lattice column and ensures the overall stability of the structure and product quality, but also allows multiple steel plates to be synchronously close to the outer wall of the angle steel, reducing the time required for positioning and fixing before welding, and improving welding efficiency.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, the clamping mechanism 4 includes a fixed box 41 with a hollow interior and a square shape. The fixed box 41 is fixedly arranged between the two vertical sections of the U-shaped frame 2 via a connecting plate. Four circumferentially evenly distributed clamping components 42 are slidably arranged on the fixed box 41, and the clamping components 42 slide along the diagonal of the fixed box 41. The clamping components 42 include two first rack plates 421 that are opposite to each other on the left and right and slide along the diagonal of the fixed box 41 in the inner cavity of the fixed box 41. The end surfaces of the first rack plates 421 away from the fixed box 41 are fixedly arranged with clamping blocks 422. A driving unit 43 for driving the clamping blocks 422 to clamp the angle steel 7 is commonly arranged on the two fixed boxes 41.

[0041] like Figure 5 , Figure 6 and Figure 7 As shown, the welding mechanism 6 includes a moving box 61 with a hollow interior, and cross bars 62 are fixedly provided on the opposite surfaces of the two electric sliders 5. A moving box 61 is commonly provided between the two cross bars 62. Four circumferentially evenly distributed tightening bars 63 are slidably provided on the moving box 61. The tightening bar 63 consists of a U-shaped section with a U-shaped opening away from the moving box 61 and two rectangular sections fixed on the vertical section of the U-shaped section. A driving unit 64 for driving the tightening bar 63 to be pressed downward is slidably provided in the inner cavity of the moving box 61. An external welding device (not shown in the figure) is provided on the tightening bar 63. The external welding equipment includes an existing welding gun, a fixing clamp, a motor and other related equipment. A spacing unit 65 for placing the steel plate 8 is provided on the cross bar 62.

[0042] During work, the staff places the four angle steels 7 on the four clamping assemblies 42 accordingly, and operates the driving unit 43, so that the driving unit 43 drives the four clamping assemblies 42 to slide along the diagonal of the fixed box 41, and the two first rack plates 421 slide along the diagonal of the fixed box 41 until the clamping blocks 422 on the two first rack plates 421 synchronously clamp and fix the inner and outer right-angle end faces of the corresponding angle steels 7, ensuring that the four angle steels 7 remain stable during welding, which helps to improve the accuracy and quality of welding.

[0043] Then the two electric sliders 5 work to drive the corresponding cross bars 62 to move synchronously, and the two cross bars 62 drive the moving box 61 to move to the designated welding position and enable the driving unit 2 64 to operate, so that the driving unit 2 64 drives the tightening strip 63 to drive the steel plate 8 to move toward the angle steel 7, and cooperates with the spacing unit 65 to make the centrally aligned steel plate 8 close to the angle steel 7 to avoid the angle steel 7 and the steel plate 8 from tilting, which affects the welding quality. Then the staff uses external welding equipment to weld the centrally aligned steel plate 8 to the corresponding outer side of the angle steel 7 in turn.

[0044] like Figure 3 , Figure 4 and Figure 5 As shown, the length of the first rack plate 421 away from the base 1 is greater than the length of the first rack plate 421 close to the base 1, and the clamping block 422 is L-shaped.

[0045] like Figure 3 , Figure 4 and Figure 5 As shown, the driving unit 43 includes a rotating rod 430, and the inner cavity of the base 1 is rotatably provided with a rotating rod 430 with an axis extending from left to right, and the rotating rod 430 is connected to an external motor (not shown in the figure). Taking the left fixed box 41 as an example for explanation, the inner cavity of the left fixed box 41 is rotatably provided with a fixed shaft 431 with an axis extending from left to right, and an active bevel gear 432 is fixedly sleeved on the fixed shaft 431, and a sprocket 433 is fixedly sleeved on the fixed shaft 431 and the rotating rod 430, and a chain is commonly arranged between the two sprockets 433 on the same side, and a first screw rod 434 with an axis extending from far away from the fixed box 41 to close to the fixed box 41 is rotatably provided at the four corners of the inner cavity of the fixed box 41.

[0046] like Figure 3 , Figure 4 and Figure 5As shown, each of the first screw rods 434 is fixedly provided with a driven bevel gear 435 meshing with the active bevel gear 432, and each of the first screw rods 434 is slidably provided with a moving block 436 threadedly matched with the first screw rod 434. Taking the clamping assembly 42 on the upper rear side of the left fixed box 41 as an example, the upper end face of the moving block 436 is fixedly provided with a first rack plate 421, and the fixed box 41 is fixedly provided with four circumferentially evenly distributed placement boxes 437, and each placement box 437 has an inner cavity that is rotatably provided with a connecting rod 438 whose axis extends from the rear lower end to the front upper end, and each connecting rod 438 is fixedly provided with a clamping gear 439, and the clamping gear 439 is meshed with another first rack plate 421.

[0047] During operation, the external motor drives the rotating rod 430 to rotate, so that the rotating rod 430 drives the fixed shafts 431 on the left and right sides to rotate synchronously through the sprocket 433 and the chain, and each fixed shaft 431 drives the corresponding active bevel gear 432 to rotate, so that the active bevel gear 432 drives the four meshing driven bevel gears 435 to rotate, and each driven bevel gear 435 drives the corresponding first screw rod 434 to rotate, and the four moving blocks 436 rotate with the corresponding first screw rod 434, so that the four moving blocks 436 drive the corresponding first rack plate 421 to move synchronously, and the first rack plate 421 drives the corresponding clamping gear 439 to rotate, and the clamping gear 439 drives the two first racks The plates 421 move toward each other until the clamping block 422 on the side close to the angle steel 7 contacts the inner right-angle end face of the corresponding angle steel 7, and at the same time, the clamping block 422 on the side away from the angle steel 7 contacts the outer right-angle end face of the corresponding angle steel 7, and the angle steel 7 placed on the clamping assembly 42 is clamped and fixed by the two first rack plates 421 of the clamping assembly 42 and the corresponding clamping blocks 422, so that the four angle steels 7 can be clamped at the diagonal of the fixed box 41, ensuring that the four angle steels 7 are distributed in a square, which is convenient for aligning and welding the steel plate 8 with the corresponding two angle steels 7, and reducing the problem of the center of gravity of the welded lattice column being offset and reducing its external load due to the inconsistency between the central axis of the steel plate 8 and the corresponding two angle steels 7 during welding.

[0048] like Figure 5 , Figure 6 , Figure 7As shown, four control boxes 68 with cavities inside and evenly distributed in the circumference are fixedly arranged on the moving box 61 at equal intervals. The upper control box 68 is taken as an example for explanation. A driving rod 66 with an axis extending from the back to the front is rotatably arranged in the cavity of the upper control box 68. A centering unit 67 for centering the control steel plate 8 is arranged on the driving rod 66. The centering unit 67 includes a convergence gear 671. A convergence gear 671 is fixedly sleeved in the middle of the driving rod 66. A driving gear 672 is fixedly sleeved on the rear side of the driving rod 66. The upper and lower ends of the inner cavity of the control box 68 are both slidably arranged with the driving gear 67 2 meshing second rack plates 673, the two second rack plates 673 are vertically symmetrical about the axis of the driving gear 672, each second rack plate 673 is fixedly provided with a T-shaped plate 674, the vertical section of each T-shaped plate 674 is provided with an alignment plate 676 for sliding up and down, an alignment spring 677 is provided between the upper end surface of the horizontal section of each T-shaped plate 674 and the corresponding alignment plate 676, a V-shaped converging plate 675 is provided on each alignment plate 676 for sliding left and right, and a converging spring 678 is provided between the converging plate 675 and the corresponding T-shaped plate 674.

[0049] like Figure 1 , Figure 5 and Figure 8 As shown, the spacing unit 65 includes an L-shaped receiving plate 651, and the two cross bars 62 are fixedly provided with receiving plates 651. The upper end surfaces of the horizontal sections of the two receiving plates 651 are rotatably provided with a reciprocating screw 652 whose axis extends from top to bottom. Two placement plates 653 are slidably sleeved on the reciprocating screw 652. Each placement plate 653 is threadedly matched with the reciprocating screw 652 and slides up and down on the vertical section of the receiving plate 651. The opposite surfaces of the two placement plates 653 on the same side are provided with placement grooves 655. Two baffles 654 symmetrical in upper and lower directions are slidably provided on each receiving plate 651. A limiting spring 656 is commonly provided between the baffle 654 and the corresponding receiving plate 651. The lower baffle 654 is a triangular section and a rectangular section from top to bottom.

[0050] During operation, the staff rotates the reciprocating screw rod 652 so that the two placement plates 653 slide toward each other on the corresponding reciprocating screw rod 652 until the height of the two placement plates 653 is the same as the height of the corresponding two angle steels 7. Then the staff places the two steel plates 8 in the placement grooves 655 on the corresponding placement plates 633, and makes the steel plates 8 located in the rectangular area of ​​the U-shaped section of the corresponding tightening strip 63, that is, the subsequent rectangular section of the tightening strip 63 can push the steel plates 8. At this time, the driving unit 2 64 drives the closing gears 671 in the four control boxes 68 to rotate synchronously and drive multiple tightening strips 63 to move toward the center of the moving box 61. The closing gear 671 drives the driving rod 66 to rotate, and the driving rod 66 drives the driving gear 672 to rotate. The driving gear 672 drives the two corresponding second rack plates 673 to slide toward each other in the inner cavity of the control box 68. The second rack plate 673 drives the corresponding T-shaped plate 674 to move synchronously, and the T-shaped plate 674 drives the corresponding closing plate 675 to move synchronously.

[0051] Until the two closing plates 675 on the upper and lower sides come into contact with the corresponding steel plates 8 and gradually squeeze the closing springs 678, the steel plates 8 are initially clamped and fixed by the elastic force generated by the closing springs 678, and then the clamped steel plates 8 come into contact with the corresponding tightening strips 63, so that the steel plates 8 are fitted and fixed on the outer walls of the two corresponding angle steels 7.

[0052] The steel plates 8 on the left and right sides are driven by the two clamping bars 63 moving toward each other to slide on the inner wall of the placement groove 655, and the steel plates 8 gradually contact the triangular section of the baffle 654, so that the baffle 654 moves downward and squeezes the limit spring 656, so that the baffle 654 can be separated from the placement groove 655. When the steel plates 8 on the left and right sides are about to be separated from the placement groove 655, they are clamped and fixed by the corresponding two clamping bars 63, so that the steel plates 8 on the left and right sides move synchronously with the corresponding two clamping bars 63 until they contact the outer walls of the corresponding two angle steels 7. At this time, the angle steels on the upper and lower sides are synchronously in contact with the corresponding two angle steels 7, so that the staff can weld the angle steels at four angles synchronously, which improves the work efficiency and avoids the problem of the steel plates 8 on the left and right sides moving downward due to gravity and tilting with the angle steel 7, which is convenient for the staff to carry out subsequent welding. Secondly, the centering unit 67 can align the center of the steel plate 8 with the central axis of the corresponding two angle steels 7, which reduces the time required for positioning and further improves the welding accuracy and efficiency.

[0053] like Figure 5 , Figure 6 , Figure 7As shown, the driving unit 2 64 includes a limit plate 641, and the inner cavity of the moving box 61 is provided with a limit plate 641 for sliding left and right. The limit plate 641 is driven by an external cylinder (not shown in the figure) to slide left and right. The circumferential outer wall of the limit plate 641 is equidistantly provided with four slide grooves 642, and each slide groove 642 is inclined downward from left to right. Taking the upper side clamping strip 63 as an example, a lower pressure plate 640 is fixedly provided on the rear side of the upper side clamping strip 63 and slides left and right on the inner wall of the slide groove 642. A plurality of ratchet teeth 643 are fixedly provided on the left end surface of the lower pressure plate 640 at equal distances from top to bottom, and a square plate 644 is fixedly provided on the right side of the lower pressure plate 640. A downward pressure spring 645 is commonly provided between the square plate 644 and the bottom of the inner cavity of the control box 68.

[0054] During operation, the external cylinder drives the limit plate 641 to slide to the left, so that the lower end surfaces of the four lower pressure plates 640 slide downward along the inclined surface of the inner wall of the slide groove 642, and at the same time, the lower pressure plate 640 drives the square plate 644 to move downward synchronously in the control box 68 and the moving box 61, so that the square plate 644 compresses the lower pressure spring 645, and the square plate 644 drives multiple ratchet teeth 643 to move downward, so that the ratchet teeth 643 and the gathering gear 671 rotate, so that the steel plate 8 and the corresponding angle steel 7 are centered, and the square plate 644 drives the tightening bar 63 to move downward gradually, and the tightening bar 63 drives the centered steel plate 8 to move toward the direction of the angle steel 7 until the steel plate 8 and the angle steel 7 are centered and tightly attached to each other, preventing the steel plate 8 and the angle steel 7 from tilting, and ensuring that multiple steel plates 8 can be centered and welded between two corresponding angle steels 7, which is beneficial to the uniform distribution and transmission of force, and improves the overall stability of the structure and product quality.

[0055] like Figure 5 , Figure 6 , Figure 7 As shown, a push plate 646 is fixedly provided on the left side of the limit plate 641, and the push plate 646 is a four-sided pyramid with a small left side and a large right side. Four circumferentially evenly distributed support plates 647 are slidably provided in the inner cavity of the moving box 61, and each support plate 647 slides along the diagonal of the moving box 61. The rear upper support plate 647 is taken as an example for explanation. The lower end surface of the rear upper support plate 647 is inclined upward from left to right and is in contact with the inclined surface of the support plate 647. A rectangular block 648 is fixedly provided at one end of the support plate 647 away from the base 1, and a roller 649 is rotatably provided at one end of the support plate 647 away from the base 1.

[0056] During operation, the external cylinder drives the limit plate 641 to slide to the left, and the limit plate 641 drives the push plate 646 to slide to the left, so that the four support plates 647 all slide upward along the inclined surface corresponding to the push plate 646, and the support plate 647 drives the rectangular block 648 to move synchronously toward the inner right-angle end surface of the angle steel 7 until the rectangular block 648 contacts the inner right-angle end surface of the angle steel 7 and the roller 649 can cooperate with the electric slider 5 to move to the specified welding position. During welding, the support plate 647 and the rectangular block 648 are used to fix and support the inner right-angle end surface of the corresponding angle steel 7, thereby improving the stability of the angle steel 7 during welding, avoiding the angle steel 7 from shifting due to uneven force during the welding process, causing the angle steel 7 to tilt with the steel plate 8, resulting in deviation in the weld position and reducing product quality.

[0057] In addition, the present invention also provides a steel structure processing welding process, comprising the following steps:

[0058] S1. Clamping the angle steel: the operator places the four angle steels 7 on the four clamping assemblies 42 accordingly, and then the external motor starts to drive the driving unit 43 to operate, so that the driving unit 43 drives the two first rack plates 421 to move diagonally toward each other in the inner cavity of the fixed box 41 until the clamping block 422 on the side close to the angle steel 7 contacts the inner right-angle end face of the corresponding angle steel 7, and at the same time, the clamping block 422 on the side away from the angle steel 7 contacts the outer right-angle end face of the corresponding angle steel 7, and the corresponding angle steel 7 is clamped at the diagonal of the fixed box 41 through the clamping assembly 42 to ensure that the four angle steels are distributed in a square, which is convenient for aligning and welding the steel plate 8 with the corresponding two angle steels 7, and avoiding the problem of the center of gravity of the welded lattice column being offset and reducing its external load due to the inconsistent center points of the angle steels 7.

[0059] S2. Alignment of the steel plate and the angle steel: The operation of the external cylinder drives the limit plate 641 and the push plate 646 to slide to the left, so that the four support plates 647 slide upward synchronously along the inclined surface of the push plate 646, and the support plate 647 drives the rectangular block 648 to move synchronously until the rectangular block 648 contacts the inner right-angle end surface of the angle steel 7 and the roller 649 can cooperate with the electric slider 5 to move to the specified welding position. During welding, the support plate 647 and the rectangular block 648 are used to fix and support the inner right-angle end surface of the corresponding angle steel 7, which can improve the stability of the angle steel 7 during welding, prevent the angle steel 7 from shifting due to uneven force on the angle steel 7, and prevent the angle steel 7 from tilting with the steel plate 8, resulting in deviation in the weld position and reducing product quality.

[0060] After the movable box 61 moves to the designated welding position, the staff rotates the reciprocating screw rods 652 on both sides of the movable box 61 until the height of the two placement plates 653 is the same as the height of the corresponding two angle steels 7, and moves the convergence plate 675 in cooperation with the centering unit 67 to align the steel plates 8 and the angle steel 7 on the upper and lower sides and the left and right sides, thereby reducing the time required for centering, improving work efficiency, and avoiding tilting between the steel plates 8 and the angle steel 7, making it easier for the staff to carry out subsequent welding.

[0061] The external cylinder drives the limit plate 641 to slide to the left, so that the limit plate 641 drives the drive unit 2 64 to operate, and the drive unit 2 64 drives the corresponding lower pressure plate 640 to move toward the movable box 61, and the lower pressure plate 640 drives the tightening bar 63 to move synchronously, so that the tightening bar 63 drives the steel plate 8 to move synchronously and makes the steel plate 8 and the corresponding two angle steels 7 centered, until the centered steel plate 8 is tightly attached to the outer wall of the angle steel 7, ensuring that multiple steel plates 8 are synchronously and tightly attached between the two corresponding angle steels 7, which not only reduces the time required for welding and improves work efficiency, but also the steel plate 8 and the angle steel 7 are centered, which is conducive to the uniform distribution and transmission of force, and improves the overall stability of the structure and product quality. Then the staff welds the connecting plate to the angle steel 7 through external welding equipment.
