Technical Field

[0001] This utility model relates to the field of steel beam welding technology, and in particular to a high-efficiency automatic welding fixture for steel beam processing. Background Technology

[0002] Steel beams are beams made of steel, also known as I-beams, and are long steel bars with an I-shaped cross-section. Steel beams are classified into section steel beams and composite beams. Section steel beams are made from hot-rolled I-beams or channel steel, while composite beams are made by welding or riveting steel plates or sections. Steel beam welding is a key process in steel structure manufacturing and is widely used in construction, bridges, shipbuilding, and other fields.

[0003] Traditional welding methods mainly rely on manual operation, which has the following problems:

[0004] High operational difficulty: Manual welding requires high technical skills from workers, especially in complex or long weld seams, where deviations are prone to occur, leading to unstable welding quality.

[0005] Low efficiency: Manually adjusting the welding position and angle is time-consuming and difficult to achieve continuous operation, which affects the overall production efficiency. Utility Model Content

[0012] Preferably, a sliding rod is slidably connected to the outer wall of the bottom of the welding table, and a connecting piece is welded to the outer wall of one end of the sliding rod. A spring is fixedly connected between the connecting piece and the welding table. A side pressure wheel is installed on the outer wall of the other end of the sliding rod.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 Example 1: A high-efficiency automatic welding fixture for steel beam processing includes a welding table 1. Adjacent drive wheels 2 are rotatably connected to one side of the outer wall of the welding table 1, and a servo motor 3 is fixedly connected to the top outer wall of the welding table 1 by screws. A pulley pair 4 is installed between the servo motor 3 and one of the drive wheels 2. The pulley pair 4 includes pulleys respectively installed on the outer wall of the drive wheel 2 and the output shaft of the servo motor 3, and a belt meshing between the two pulleys.

[0025] The servo motor 3 transmits power to the drive wheel 2 through the pulley pair 4, driving the welding table 1 to move linearly along the steel beam. The pulley pair 4 uses a high-strength synchronous belt to avoid slippage.

[0026] In this embodiment, the servo motor 3 can drive the steel beam to move at a constant speed through the pulley pair 4, and the welding machine 10 is uniformly controlled by the electronic controller 18, which can realize the automation of positioning and welding, and help improve the welding efficiency.

[0027] Example 2: A high-efficiency automatic welding fixture for steel beam processing. The welding table 1 has a top plate 5 welded to its top outer wall, and a horizontal lead screw 6 is screwed to one side of the top plate 5's outer wall. A connecting sleeve 7 is rotatably connected to one end of the horizontal lead screw 6's outer wall, and a vertical lead screw 8 is screwed to the inner wall of the connecting sleeve 7. A mounting base 9 is rotatably connected to the bottom outer wall of the vertical lead screw 8, and a welding machine 10 is fixedly connected to the inner wall of the mounting base 9. A first guide rod 16 is welded to one side of the connecting sleeve 7's outer wall, and the first guide rod 16 is slidably connected to the inner wall of the top plate 5. A second guide rod 17 is welded to the top outer wall of the mounting base 9, and the second guide rod 17 is slidably connected to the inner wall of the connecting sleeve 7.

[0028] When the horizontal lead screw 6 rotates, the connecting sleeve 7 moves horizontally along the first guide rod 16; the vertical lead screw 8 controls the vertical lifting and lowering of the mounting base 9, and the second guide rod 17 prevents the mounting base 9 from rotating, ensuring the straightness of the welding machine 10 path.

[0029] In this embodiment, the horizontal lead screw 6 and the vertical lead screw 8, together with the first guide rod 16 and the second guide rod 17, realize the two-dimensional precision adjustment of the welding machine 10, eliminate human operation errors, ensure accurate welding position, reduce the difficulty of welding operation, and through the synergistic effect of the drive wheel 2, the side pulley 11 and the side pressure wheel 15, the welding table 1 is fixed in multiple directions during the welding process of the steel beam, which increases the stability of movement.

[0030] A symmetrically distributed side pulley 11 is rotatably connected to one side of the top outer wall of the welding table 1. A sliding rod 12 is slidably connected to the bottom outer wall of the welding table 1, and a connecting piece 13 is welded to the outer wall of one end of the sliding rod 12. A spring 14 is fixedly connected between the connecting piece 13 and the welding table 1. A side pressure wheel 15 is installed on the outer wall of the other end of the sliding rod 12. A steel beam is slidably connected to the outer walls of the drive wheel 2, the side pulley 11, and the side pressure wheel 15.

[0031] Side pulleys 11 are symmetrically distributed on the top of welding table 1, and together with drive wheel 2, they fit against the steel beam. Side pressure wheel 15 applies dynamic pressure through spring 14 to ensure that drive wheel 2 is in close contact with the steel beam and does not deviate.

[0032] An electric controller 18 is installed on the outer wall of the top of the welding station 1 on one side of the top plate 5, and the electric controller 18 is connected to the servo motor 3 and the welding machine 10 via a signal line.

[0033] The electronic controller 18 presets welding parameters such as speed and temperature, and adjusts the speed of the servo motor 3 and the start and stop of the welding machine 10 in real time through signal lines to achieve unattended operation.

[0034] Working principle:

[0035] Loading and fixing: The steel beam is placed on the drive wheel 2 and the side pulley 11. The side pressure wheel 15 presses the side wall of the steel beam under the action of the spring 14 to form a three-point positioning.

[0036] Automatic feeding: The electronic controller 18 starts the servo motor 3, which drives the drive wheel 2 to rotate through the pulley pair 4, and the welding table 1 moves forward at a constant speed along the side wall of the steel beam.

[0037] Welding execution: The welding machine 10 is adjusted to the target position according to the preset path by the horizontal lead screw 6 and the vertical lead screw 8 to complete the weld. The first guide rod 16 and the second guide rod 17 ensure the movement accuracy.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
