The structure includes a base plate, a robotic arm mounted on the top of the base plate, and a laser welding component mounted on the end of the robotic arm. It also includes a centering component comprising a telescopic right-angle frame. A sliding plate is fixedly connected to the upper surface of the telescopic right-angle frame, and a pressing frame is fixedly connected to the end of the sliding plate away from the telescopic right-angle frame.

During the alignment process, friction causes a ball to rotate inside a support rod, reducing resistance and improving stability during centering.

Description

Technical Field

[0001] The present invention relates to the technical field of I-beam crossbeam welding, and specifically provides a centering auxiliary structure for I-beam crossbeam welding. Background Technique

[0002] The I-beam crossbeam is a steel member with a cross-sectional shape similar to the Chinese character "工" and is named after its cross-sectional shape. The I-beam crossbeam has high bending strength and stability and is widely used in fields such as construction, bridges, and mechanical manufacturing. The main characteristics of the I-beam crossbeam include: high strength and stiffness: it can withstand large loads and is suitable for structures with large spans; good stability: the I-shaped cross-sectional design gives it good stability when compressed and bent; easy installation: the I-beam crossbeam is usually connected by bolts or welded, and the installation is simple and fast; When performing welding operations on the I-beam crossbeam, a hoisting device is usually used in cooperation with manual support to position the I-beam crossbeam. Due to the flexible characteristics of the sling, the heavy workpiece is in an underconstrained state in the air and is prone to swinging. Moreover, the hoisting device lacks the micro-motion adjustment ability for heavy components. During the fine-tuning stage of the I-beam crossbeam docking, it is easy for the workpiece to get stuck or have excessive displacement due to excessive friction, forcing the operator to use means such as hammering to forcibly push the I-beam crossbeam into place, which is rather troublesome to correct and affects the production efficiency of the I-beam crossbeam.

A two-way telescopic frame is provided at the end of the centering rod. The two-way telescopic frame limits the centering rod, improving its stability during movement and preventing it from tilting under the action of the threaded rod. The lower surface of the telescopic right-angle frame contacts the bottom of the base plate, which uses the base plate to press and limit the telescopic right-angle frame, improving its stability during movement. When the movable frame moves, it pushes the telescopic right-angle frame to slide on the surface of the centering rod through the sliding hole frame. The upper surface of the telescopic right-angle frame is telescopic, allowing the height of the telescopic right-angle frame to be adjusted along with the electric push rod.

[0007] Furthermore, the telescopic right-angle frame is provided in four units, and the four telescopic right-angle frames are arranged in two groups, with two units in each group. The two groups of telescopic right-angle frames are symmetrically arranged with the base plate as the center. The inner wall of the telescopic right-angle frame is slidably connected to the surface of the centering rod. There are two centering rods, and the two centering rods are symmetrically arranged with the base plate as the center. The lower surface of the telescopic right-angle frame is in contact with the bottom of the base plate, and the upper surface of the ball extends to the top outer end of the support rod.

[0010] Furthermore, the end of the expansion plate away from the contact plate passes through the extrusion frame and extends into the interior of the extrusion frame. Two expansion plates are provided inside the extrusion frame, and the two expansion plates are arranged symmetrically above and below the extrusion frame. The end of the triangular block away from the stabilizing plate contacts the inner wall of the inclined groove.

[0011] Furthermore, the unloading component includes a limiting frame, the top of which is fixedly connected to the bottom of the base plate, a sliding hole rod is slidably connected to the surface of the limiting frame, an inclined plate is hinged to the top of the sliding hole rod, the end of the inclined plate away from the sliding hole rod is sleeved on the lower surface of the bracket, a telescopic rod is fixedly connected to the bottom of the sliding hole rod, and the end of the telescopic rod away from the sliding hole rod is fixedly connected to the bottom of the centering rod.

[0012] Furthermore, there are two limiting frames, which are symmetrically arranged around the roller as the center. The roller is located inside the groove, and the bottom of the bracket penetrates the bottom plate and extends to the bottom outer end of the bottom plate.

[0013] The present invention has the following beneficial effects: This invention's telescopic right-angle frame, when moved, uses a sliding plate to push the extrusion frame into contact with the surface of the I-beam crossbeam. As the two extrusion frames move closer to each other, they push the I-beam crossbeam to align, facilitating welding. During the alignment process, friction causes the ball bearings to rotate inside the support rod, reducing resistance and improving stability during centering. The sliding plate contacts the inner wall of the sliding hole frame, which, under the positioning plate, positions the sliding plate, enhancing its stability during centering. The electric actuator pushes the sliding plate up and down during operation, adjusting the position of the extrusion frame to align with the center surface of I-beam crossbeams of different specifications, improving practicality.

[0014] The extrusion frame of this invention pushes the two I-beam crossbeams closer to each other as the moving frame moves, thereby using the moving frame to splice the two I-beam crossbeams together, completing the splicing and welding of the I-beam crossbeams, and improving the convenience of welding alignment of the I-beam crossbeams.

[0015] After the stabilizing plate of this invention is subjected to force, it pushes the triangular block to move into the interior of the extrusion frame. When the triangular block moves, it pushes the two expansion plates to move away from each other through the inclined groove. When the two expansion plates move away from each other, they push the contact plate to contact the upper and lower inner walls of the I-beam. Thus, the contact plate is used to extrude and fix the I-beam, which improves the stability of the I-beam during welding and avoids misalignment due to vibration.

[0016] When the bracket of this invention moves upward, it pushes the roller upward. The roller will slightly lift the H-beam crossbeam, increasing the friction between the roller and the H-beam crossbeam. At this time, when the drive device is started to drive the roller to rotate, the roller pushes the H-beam crossbeam to move on the surface of the support rod through friction, thereby completing the unloading operation of the H-beam crossbeam and improving the convenience of unloading the H-beam crossbeam after welding.

The unloading component 9 includes a roller 50, a bracket 51 is rotatably connected to the end surface of the roller 50, a drive device 52 is mounted on the surface of the bracket 51, and the output end of the drive device 52 is fixedly connected to the end of the roller 50.

A transfer frame 21 is fixedly connected to the top of the base plate 1. Multiple support rods 27 are fixedly connected to the inner wall of the transfer frame 21. Multiple ball bearings 29 are rotatably connected to the inner wall of the support rods 27. A motor 20 is fixedly connected to the end of the stabilizing frame 6.

A positioning plate 28 is fixedly connected to the top of the movable frame 32. A sliding hole frame 34 is slidably connected to the surface of the positioning plate 28. When the telescopic right-angle frame 30 moves, it pushes the extrusion frame through the sliding plate 33. The two extrusion frames 35 contact the surface of the I-beam beam 2. When the two extrusion frames 35 move closer to each other, they push the I-beam beam 2 to move in a straightening position, so that the two I-beam beams 2 are aligned for welding. During the straightening operation, the I-beam beam 2 will rotate the ball 29 inside the support rod 27 through friction, reducing the resistance of the I-beam beam 2 during the straightening operation and improving the stability of the I-beam beam 2 during the centering operation. The surface of the slide plate 33 contacts the inner wall of the sliding hole frame 34. The sliding hole frame 34 positions the slide plate 33 under the positioning plate 28, improving the stability of the slide plate 33 during the centering operation. During operation, the electric push rod 31 pushes the slide plate 33 up and down. The position of the extrusion frame 35 is adjusted by the slide plate 33, so that the extrusion frame 35 can correspond to the center surface of the I-beam beam 2 of different specifications, improving practicality.

[0025] There are four telescopic right-angle frames 30, arranged in two groups of two. The two groups of telescopic right-angle frames 30 are symmetrically arranged with the base plate 1 as the center. The inner wall of the telescopic right-angle frame 30 is slidably connected to the surface of the centering rod 24. There are two centering rods 24, symmetrically arranged with the base plate 1 as the center. The lower surface of the telescopic right-angle frame 30 is in contact with the bottom of the base plate 1. The upper surface of the ball 29 extends to the top outer end of the support rod 27. The extrusion frame 35 pushes the two I-beam crossbeams 2 to move closer to each other as the moving frame 32 moves, thereby using the moving frame 32 to splice the two I-beam crossbeams 2 together, completing the splicing and welding of the I-beam crossbeams 2, and improving the convenience of welding and centering the I-beam crossbeams 2.

[0026] The bottom of the I-beam beam 2 contacts the top of the ball 29, the inner wall of the sliding hole frame 34 is slidably connected to the surface of the positioning plate 28, the surface of the slide plate 33 is slidably connected to the inner wall of the sliding hole frame 34, the center surface of the moving frame 32 contacts the inner wall of the stabilizing frame 6, the end of the screw 22 away from the motor 20 passes through the stabilizing frame 6 and is rotatably connected to the inner wall of the stabilizing frame 6, and the surface of the screw 22 is threadedly connected to the inner wall of the moving frame 32.

[0027] The stabilizing component 8 includes an expansion plate 45, with a contact plate 42 fixedly connected to the end of the expansion plate 45. A groove 44 is provided at the end of the expansion plate 45 away from the contact plate 42. A bidirectional elastic rod 43 is fixedly connected to the inner wall of the expansion plate 45. The center surface of the bidirectional elastic rod 43 is fixedly connected to the inner wall of the extrusion frame 35. A spring rod 41 is fixedly connected to the inner wall of the triangular block 46. The end of the spring rod 41 away from the triangular block 46 is fixedly connected to the inner wall of the extrusion frame 35. When the stabilizing plate 40 is subjected to force, it pushes the triangular block 46 to move into the interior of the extrusion frame 35. When the triangular block 46 moves, it pushes the two expansion plates 45 to move away from each other through the groove 44. When the two expansion plates 45 move away from each other, they push the contact plate 42 to contact the upper and lower inner walls of the I-beam beam 2. Thus, the contact plate 42 is used to press and fix the I-beam beam 2, improving the stability of the I-beam beam 2 during welding and preventing it from being misaligned due to vibration.

[0028] The end of the expansion plate 45 away from the contact plate 42 passes through the extrusion frame 35 and extends into the interior of the extrusion frame 35. Two expansion plates 45 are provided inside the extrusion frame 35. The two expansion plates 45 are symmetrically arranged vertically with the extrusion frame 35 as the center. The end of the triangular block 46 away from the stabilizing plate 40 contacts the inner wall of the inclined groove 44.

[0029] The unloading component 9 includes a limiting frame 53. The top of the limiting frame 53 is fixedly connected to the bottom of the base plate 1. A sliding hole rod 54 is slidably connected to the surface of the limiting frame 53. An inclined plate 55 is hinged to the top of the sliding hole rod 54. The end of the inclined plate 55 away from the sliding hole rod 54 is sleeved on the lower surface of the bracket 51. A telescopic rod 56 is fixedly connected to the bottom of the sliding hole rod 54. The end of the telescopic rod 56 away from the sliding hole rod 54 is fixedly connected to the bottom of the centering rod 24. When the bracket 51 moves upward, it pushes the roller 50 to move upward. The roller 50 will slightly lift the I-beam crossbeam 2, increasing the friction between the roller 50 and the I-beam crossbeam 2. At this time, when the drive device 52 is started to drive the roller 50 to rotate, the roller 50 pushes the I-beam crossbeam 2 to move on the surface of the support rod 27 through friction, thereby completing the unloading operation of the I-beam crossbeam 2 and improving the convenience of unloading the I-beam crossbeam 2 after welding.

[0030] There are two limit brackets 53. The two limit brackets 53 are symmetrically arranged with the roller 50 as the center. The roller 50 is located inside the groove 5. The bottom of the bracket 51 passes through the base plate 1 and extends to the bottom outer end of the base plate 1.

[0031] In use, after hoisting the I-beam beam 2 above the base plate 1, the operator lowers the I-beam beam 2 to the top of the support rod 27 and into contact with the rolling ball 29. After placing the two I-beam beams 2 on top of the support rod 27, when the power device 25 is started and the threaded rod 26 is rotated, the threaded rod 26 will drive the two centering rods 24 to move closer to each other. When the centering rods 24 move, they push the telescopic right-angle frame 30 towards the surface of the I-beam beam 2. When the telescopic right-angle frame 30 moves, it pushes the extrusion frame 35 and the I-beam beam 2 through the sliding plate 33. The surfaces of the steel beams 2 are in contact. When the two extrusion frames 35 move closer to each other, they push the I-beam beams 2 to move in an upright position, so that the two I-beam beams 2 are aligned for welding. During the uprighting operation, the friction of the rollers 29 drives the I-beam beams 2 to rotate inside the support rod 27, reducing the resistance of the I-beam beams 2 during the uprighting operation and improving the stability of the I-beam beams 2 during the centering operation. The surface of the sliding plate 33 is in contact with the inner wall of the sliding hole frame 34, and the sliding hole frame 34 is positioned on the positioning plate. Positioning the slide plate 33 under the positioning of 28 improves the stability of the slide plate 33 during centering operations. The electric actuator 31 pushes the slide plate 33 up and down during operation, adjusting the position of the extrusion frame 35 so that it can correspond to the center surface of the I-beam crossbeam 2 of different specifications, improving practicality. After the extrusion frame 35 is aligned with the I-beam crossbeam 2, the motor 20 is started to drive the screw 22 to rotate. The rotation of the screw 22 drives the two moving frames 32 on the surface to move closer to each other, at which point the extrusion frame 35... As the moving frame 32 moves, it pushes the two I-beam beams 2 to move closer to each other, thereby using the moving frame 32 to splice the two I-beam beams 2 together, completing the splicing and welding of the I-beam beams 2, improving the convenience of welding alignment of the I-beam beams 2. When the I-beam beams 2 move closer to each other, it will drive the ball 29 to rotate, using the ball 29 to reduce the movement resistance of the I-beam beams 2. After the two I-beam beams 2 are connected, the robotic arm 3 will operate the laser welding component 4 to perform welding operations on the I-beam beams 2. When the extrusion frame 35 moves, it pushes the stabilizing plate 40 into contact with the surface of the I-beam beam 2. Both ends of the stabilizing plate 40 extend to the outer ends of the extrusion frame 35, increasing the contact area between the extrusion frame 35 and the I-beam beam 2, thereby improving the alignment effect of the I-beam beam 2 and preventing insufficient force points from affecting the alignment and causing misalignment. After being stressed, the stabilizing plate 40 pushes the triangular block 46 to move inwards towards the extrusion frame 35. During this movement, the triangular block 46 pushes the two expansion plates 45 away from each other via the inclined groove 44. As the two expansion plates 45 move away from each other, they push the contact plate 42 into contact with the upper and lower inner walls of the I-beam beam 2. This allows the contact plate 42 to press and fix the I-beam beam 2, improving its stability during welding and preventing misalignment due to vibration. After the upper surface of the I-beam beam 2 is welded, when the electric actuator 31 is activated to push the slide plate 33 upward, the slide plate 33 pushes the I-beam beam 2 upward through the extrusion frame 35. At this time, a distance will be moved between the bottom of the I-beam beam 2 and the top of the base plate 1, which facilitates the laser welding component 4 to weld the bottom of the I-beam beam 2 and perform comprehensive welding on the I-beam beam 2, avoiding secondary welding. After welding is completed, the I-beam beam 2 is lowered to the top of the support rod 27. At this time, when the threaded rod 26 pushes the two centering rods 24 to move away from each other, the centering rods 24 will push the extrusion frame 35 to separate from the I-beam beam 2 through the telescopic right angle frame 30. The stabilizing plate 40 and the contact plate 42 will be reset under the action of the elastic rod 41 and the bidirectional elastic rod 43, so as to unload the welded I-beam beam 2. When the center rods 24 move away from each other, they will pull the telescopic rod 56 to extend. After the telescopic rod 56 extends to its limit, it will pull the sliding rod 54 to slide on the surface of the limit frame 53. When the sliding rod 54 moves, it will push the angle of the inclined plate 55 to change. When the inclined plate 55 moves, it will push the bracket 51 to move upward. When the bracket 51 moves upward, it will push the roller 50 to move upward. The roller 50 will slightly lift the I-beam beam 2, increasing the friction between the roller 50 and the I-beam beam 2. At this time, when the drive device 52 is started to drive the roller 50 to rotate, the roller 50 will push the I-beam beam 2 to move on the surface of the support rod 27 through friction, thereby completing the unloading operation of the I-beam beam 2 and improving the convenience of unloading the I-beam beam 2 after welding. When the center rods 24 move closer to each other, the center rods 24 will push the telescopic rod 56 to retract. At this time, the roller 50 will fall into the inside of the groove 5 and be stored.
