[0002] In order to meet the use requirements, steel structures need to be welded. Manual welding of steel structures is time-consuming and labor-intensive, and is prone to deviation, which affects the welding quality and has low welding efficiency. With the rapid development of society, the types of steel structure welding devices are gradually increasing, and their functions are constantly improving.

[0003] In the process of clamping welded parts, the commonly used structure is to align two welded parts and place them between two clamping plates. Once the welded parts are offset during welding, the welding quality will be affected. In addition, the clamping plate structure is fixed and it is inconvenient to adjust the welding position, which has the problem of poor practicality. In addition, it is necessary to manually hold the welding gun and move the welding surface for welding, which is time-consuming and laborious. Therefore, a steel structure welding device and a method of use that are easy to dock are needed to solve the above technical problems. Summary of the invention

[0004] In order to solve the above-mentioned technical problems, the present invention provides a steel structure welding device and a use method that are easy to connect, which facilitates steel structure welding and improves work efficiency and welding quality.

[0005] The technical solution adopted in the embodiment of the present invention is: a steel structure welding device that is easy to connect and can connect a first steel structure and a second steel structure to be welded, and is characterized in that it includes a support seat, a support rod and a support plate respectively connected to the support seat, the support rod clamps the first steel structure through a first clamping assembly, and the support plate clamps the second steel structure through a second clamping assembly. The center lines of the first clamping assembly and the second clamping assembly always coincide during the activity, so that the first steel structure and the second steel structure can be aligned with the welding surface.

[0006] Furthermore, the support rod is rotatably connected to the first fixing seat via a first pillar, the support plate is rotatably connected to the second fixing seat via a second pillar, and the first clamping assembly and the second clamping assembly are respectively provided on opposite sides of the first fixing seat and the second fixing seat.

[0007] Furthermore, the support rod is slidably connected to the support seat via a slide groove, and a limiting rod penetrates through the support rod and is inserted into the slide groove to limit the movement of the support rod.

[0008] Furthermore, the first clamping assembly includes a first bidirectional screw arranged on the first fixed seat and a first clamping plate symmetrically arranged on the first bidirectional screw, and the second clamping assembly includes a second bidirectional screw arranged on the second fixed seat and a second clamping plate symmetrically arranged on the second bidirectional screw, and the center lines of the two first clamping plates and the center lines of the two second clamping plates always coincide with each other.

[0009] Furthermore, the moving directions of the first clamping plate and the second clamping plate are parallel and perpendicular to the moving direction of the welding gun.

[0010] Furthermore, the welding gun is arranged between the first fixing seat and the second fixing seat, and is connected to the support frame through a hydraulic cylinder, and the support frame is connected to the support seat.

[0011] Furthermore, the support plate is rotatably connected to the support seat via a threaded rod, and driving the threaded rod to rotate can drive the support plate to perform linear motion along the direction of the threaded rod body.

[0012] Furthermore, the support rod is connected to the first pillar by a first screw, the first pillar is connected to the first fixing seat, the support plate is connected to the second pillar by a second screw, and the second pillar is connected to the second fixing seat by a sleeve.

[0015] Adjusting the position of the limiting rod in the sliding groove so that after the first steel structure clamped by the first clamping plate moves to a set position, the limiting rod and the supporting rod are fixed to each other;

[0016] Driving the support plate to drive the second steel structure clamped by the second clamping plate to approach the welding surface of the first steel structure;

[0017] The welding gun is moved to the welding surface, and the welding surface is moved to perform welding.

[0018] The advantages and positive effects of the present invention are:

[0019] 1. Set up the clamping assembly, and drive the clamping plate to make linear motion through the rotation of the bidirectional lead screw. Whether it is moving or rotating, the center lines of the two clamping assemblies always coincide, which can ensure the precise docking of the butt joints, and then ensure the welding progress.

[0028] 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.

[0029] It should be noted that the first steel structure and the second steel structure mentioned in this application are both circular in shape.

[0030] A steel structure welding device that is easy to connect can connect a first steel structure and a second steel structure to be welded, including a support seat 1, a support rod 3 and a support plate 12 respectively connected to the support seat 1, the support rod 3 clamps the first steel structure through a first clamping assembly, and the support plate 12 clamps the second steel structure through a second clamping assembly. The center lines of the first clamping assembly and the second clamping assembly always coincide during the activity, so that the first steel structure and the second steel structure can be aligned with the welding surface.

[0031] Preferably, the support rod 3 is rotatably connected to the first fixed seat 6 through the first pillar 19, and the support plate 12 is rotatably connected to the second fixed seat 23 through the second pillar 20. The first fixed seat 6 and the second fixed seat 23 are provided with a first clamping assembly and a second clamping assembly on opposite sides thereof. In this embodiment, the first fixed seat 6 can rotate relative to the first pillar 19, thereby driving the first clamping assembly to rotate, and the second pillar 20 can rotate relative to the sleeve 13, and the sleeve 13 drives the second fixed seat 23 to rotate, thereby driving the second clamping assembly to rotate. The two clamping assemblies after docking drive the steel structure to rotate while completing the welding. It is only necessary to fix the welding gun, which reduces the intensity of manual labor and greatly improves the welding quality. In addition, the first clamping assembly clamps the first steel structure, and the second clamping assembly clamps the second steel structure. Since the center lines of the two clamping assemblies always coincide, it is possible to ensure that the welding surfaces of the two steel structures are accurately docked, further ensuring the welding quality.

[0032] Preferably, the support rod 3 is slidably connected to the support seat 1 through the slide groove 2, and the limit rod 4 penetrates the support rod 3 and is inserted into the slide groove 2 to limit the movement of the support rod 3. When in use, the first steel structure can be clamped by the first clamping assembly according to the size of the first steel structure, and then the welding surface of the first steel structure is moved to the right below the welding gun 16 by moving the support rod 3 in the slide groove 2, and the support rod 3 and the slide groove 2 are fixed to each other.

[0033] Preferably, the support plate 12 is rotatably connected to the support seat 1 through the threaded rod 11, and driving the threaded rod 11 to rotate can drive the support plate 12 to move linearly along the direction of the rod of the threaded rod 11. The movement of the support plate 12 can drive the movement of the second fixing seat 23 and the second clamping assembly, so that the welding surface of the second steel structure is aligned with the welding surface of the first steel structure.

[0034] Preferably, the first clamping assembly includes a first bidirectional screw 8 arranged on the first fixed seat 6 and a first clamping plate 9 symmetrically arranged on the first bidirectional screw 8, and the second clamping assembly includes a second bidirectional screw 25 arranged on the second fixed seat 23 and a second clamping plate 26 symmetrically arranged on the second bidirectional screw 25, and the center lines of the two first clamping plates and the center lines of the two second clamping plates always coincide.

[0035] Reference Figure 1As shown, a slide groove 2 is provided at the left end of the upper surface of the support seat 1, and a support rod 3 is slidably connected inside the slide groove 2. A first pillar 19 is installed on the top of the support rod 3. A first screw 21 penetrates the support rod 3 and is embedded in the first pillar 19. By changing the relative position of the first screw 21 and the first pillar 19, the length of the first pillar 19 inserted into the support rod 3 can be adjusted, thereby changing the longitudinal height of the first support pillar 19. As the support rod 3 moves laterally in the slide groove 2, it can drive the first steel structure to be welded to be close to or away from the welding gun 16.

[0036] like Figure 4 As shown, the inner engaging installation of the limit rod 4 at the bottom of the support rod 3, the limit rod 4 penetrates the support rod 3 and then embeds into the slide groove 2 to realize the mutual fixation of the limit plate 4 and the support rod and the mutual fixation of the support rod 3 and the slide groove 2, and the limit rod 4 at the bottom of the support rod 3 is pulled upward, so that the support rod 3 and the slide groove 2 can slide relative to each other, and the support rod 3 can be moved left and right and adjusted to a suitable position, so as to drive the first fixing seat 6 on the right side of the support rod 3 to move to a suitable position, and the suitable position here refers to that the welding surface of the first steel structure is located directly below the welding gun 16, which is also a set welding position;

[0037] A second motor 10 is installed on the right side of the support seat 1, and a threaded rod 11 is connected to the output end of the second motor 10. A support plate 12 is threadedly installed on the surface of the threaded rod 11. A second screw 22 penetrates the support plate 12 and is embedded in the second pillar 20. Changing the relative position of the second screw 22 and the second pillar 20 can drive the sleeve 13 at the upper end of the second pillar 20 to rise or fall. A second fixed seat 23 is installed on the left side of the sleeve 13, and a second clamping assembly is provided on the second fixed seat 23 for clamping the second steel structure.

[0038] The first motor 5 is installed on the left side of the first pillar 20, and the output end of the first motor 5 is connected to the first fixing seat 6, and the first steel structure to be welded is placed in the first fixing seat 6. When in use, the first motor 5 is turned on to drive the first fixing seat 6 to rotate, thereby driving the first steel structure clamped in the first fixing seat 6 to rotate, and at the same time, the second fixing seat 23 on the other side and the second steel structure can also rotate at the same frequency, and the two cooperate with the welding gun 16 to complete the welding operation while rotating, which is more efficient;

[0039] like Figure 2As shown, a first clamping assembly is provided in the first fixing seat 6, and the first clamping assembly includes a first bidirectional lead screw 8, a first clamping plate 9 and a first motor 7. The first motor 7 is installed on the rear side of the first fixing seat 6, and the output end of the first motor 7 is connected to the first bidirectional lead screw 8. The first clamping plates 9 are symmetrically provided on the first bidirectional lead screw 8 to clamp the first steel structure to be welded. When the first motor 7 is turned on, the first motor 7 drives the first bidirectional lead screw 8 to rotate, and the rotation of the first bidirectional lead screw 8 is converted into a linear motion of the first clamping plate 9, so that the two first clamping plates 9 can be driven to approach each other to clamp the first steel structure to be welded;

[0040] In this embodiment, a second clamping assembly having a structure similar to that of the first clamping assembly is provided in the second fixed seat 23, and the second clamping assembly includes a second bidirectional lead screw 25, a second clamping plate 26 and a second motor 24. The output end of the second motor 24 is connected to the second bidirectional lead screw 25, which in turn drives the second clamping plate 26 symmetrically arranged on the second bidirectional lead screw 25 to clamp the second steel structure to be welded, which will not be elaborated in detail here. The center lines of the two first clamping plates 9 and the center lines of the two second clamping plates 26 always coincide with each other, which can ensure the accuracy of the welding surface connection of the two clamped steel structures, and greatly improve the welding quality. When in use, according to the size of the first steel structure, the two first clamping plates 9 are driven to move in the direction of the first steel structure to clamp the first steel structure, and the moving direction of the first clamping plate 9 is parallel to the moving direction of the second clamping plate 26, and both are perpendicular to the moving direction of the welding gun 16.

[0041] like Figure 4 As shown, the center line of the first clamping plate 9 coincides with the center line of the second clamping plate, and the welding gun 16 can be moved to the above center line. The center line of the first clamping plate 9 and the second clamping plate 26 can rotate simultaneously and cooperate with the welding gun 16 to complete multi-faceted welding operations.

[0042] After clamping and limiting the second steel structure in the second fixed seat 23, turn on the second motor 10, and the second motor 10 drives the threaded rod 11 to rotate, thereby driving the support plate 12 and the second steel structure to move to the left, so as to facilitate the movement of the steel structure on the right side of the support seat 1 to dock with the steel structure on the left side to prevent the steel structure from shifting. It should be noted that in the technical solution of the present application, the position of the first steel structure on the left side is adjusted first, and its welding surface is moved to the set position, and then the second steel structure on the right side is moved to make the second steel structure align with the first steel structure for docking, which improves the accuracy of docking and helps to improve the welding quality.

[0043] A support frame 14 is installed at the rear end of the upper surface of the support seat 1, a hydraulic cylinder 15 is installed at the upper end of the support frame 14, and a welding gun 16 is installed at the lower end of the hydraulic cylinder 15. When the hydraulic cylinder 15 is turned on, the hydraulic cylinder 15 drives the welding gun 16 to move downward, and the welding gun 16 is aimed at the welding surface of the two steel structures for welding. With the synchronous rotation of the two steel structures, the welding operation is completed. Of course, the hydraulic cylinder 15 with a longitudinal height adjustment can be used to move the electric welding gun 16 vertically to the welding surface. Of course, another horizontally adjustable hydraulic cylinder can also be set to drive the welding gun 16 to move along the welding surface when the welding surface is not moving to perform welding. No specific limitation is made here.

[0044] like Figure 1 As shown, a dust suction pipe 17 is installed on the upper surface of the support base 1, and the dust suction pipe 17 is connected to an external vacuum cleaner. The vacuum cleaner collects and cleans the debris generated during welding through the dust suction pipe 17. A screen 18 is installed inside the dust suction pipe 17. The screen 18 can filter impurities to prevent impurities from entering and clogging the vacuum cleaner. Unscrewing the screws on the outside of the dust suction pipe 17 makes it easy to disassemble the screen 18.

[0045] The method of using the steel structure welding device that is easy to butt joint as described above comprises the following steps:

[0046] Adjust the position of the limiting rod 4 in the slide groove 2 so that the first steel structure clamped by the first clamping plate 9 moves to the set position, and then the limiting rod 4 and the support rod 3 are fixed to each other;

[0047] The driving support plate 12 drives the second steel structure clamped by the second clamping plate 26 to approach the welding surface of the first steel structure;

[0048] Move the welding gun to the welding surface and move the welding surface to weld.

[0049] The advantages and positive effects of the present invention are:

[0050] 1. Set up the clamping assembly, and drive the clamping plate to make linear motion through the rotation of the bidirectional lead screw. Whether it is moving or rotating, the center lines of the two clamping assemblies always coincide, which can ensure the precise docking of the butt joints, and then ensure the welding progress. The two sets of clamping assemblies can adapt to steel structures of different sizes, which is very flexible and convenient;

[0051] 2. Set up mutually matched slide grooves and support rods, threaded rods and support plates. The support rods are relatively fixed to the slide grooves through the limit rods. The threaded rods rotate to drive the support plates and the second steel structure in the clamping state to move toward the first steel structure, which can accurately butt the welding surface, prevent welding deviation, and improve welding quality;

[0052] 3. A cleaning mechanism is set up, and the vacuum tube is connected to an external vacuum cleaner. The vacuum cleaner can collect the debris generated during welding through the vacuum tube, which is convenient for cleaning welding debris and ensuring a clean work surface. The screen in the vacuum cleaner can filter impurities to prevent impurities from entering and clogging the vacuum cleaner.

[0053] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
