Description

Technical Field

[0001] This invention belongs to the field of winding machine technology, specifically referring to a steel component welding and assembly machine. Background Technology

[0002] In steel structure construction, bridge engineering, and heavy machinery manufacturing, H-beams and box-section steel components are widely used in critical parts such as load-bearing frames and supporting columns due to their excellent mechanical properties, load-bearing capacity, and structural stability. As the core process of component processing, steel component welding and assembly requires precise positioning and temporary fixation of the web and flanges (for H-beams) or web and cover plates (for box-sections) to lay the foundation for subsequent welding processes. Therefore, the adaptability and positioning accuracy of the assembly machine become key factors affecting the processing efficiency and quality of steel components.

[0003] Steel component welding and assembly is a core process in component processing, requiring precise positioning and temporary fixation of each plate in the steel component to lay the foundation for subsequent welding processes. Due to the fundamental differences in the cross-sectional structures of H-beams and box-sections, existing assembly machines are mostly specialized equipment designed for a single type of steel component. Their positioning mechanisms have fixed structures and adjustment ranges, making them unable to flexibly adapt to the cross-sectional dimensions and plate arrangements of different types of steel components. If both H-beams and box-sections need to be processed, companies must purchase two separate specialized assembly machines, increasing equipment investment costs and workshop space requirements, reducing production efficiency, and increasing production management complexity. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide a steel component welding and assembly machine to at least partially solve the problems mentioned in the background art.

The horizontal distance between the symmetrically arranged clamps is adjustable. Multiple sets of clamps are provided along the conveying direction of the roller conveyor line. The fixture includes two sets of positioning plates, namely a fixed positioning plate and a movable positioning plate. The movable positioning plate is configured to have an adjustable vertical position and horizontal spacing relative to the fixed positioning plate. The movable positioning plate and the fixed positioning plate are used together to clamp and position the lateral plate. The positioning plate has multiple sets of push-pull grooves on its side wall. A fixed plate and a conveying plate are slidably arranged in the push-pull grooves. A side conveying roller is rotatably arranged on the conveying plate. The push roller is configured to be raised and lowered between two adjacent sets of conveying rollers. The middle of the push roller corresponds to the middle of the conveying roller. Both the push roller and the conveying roller are used to support the horizontal plate. The push roller is used to adjust the height of the horizontal plate relative to the side clamping plate.

[0006] Furthermore, the fixture also includes a first lifting cylinder, the fixed positioning plate is located at the free end of the first lifting cylinder, and the lower end of the fixed positioning plate near the movable positioning plate is provided with a support plate. The support plate is used to support the lateral plate and adjust the relative height between the lower end of the lateral plate and the conveying roller by lifting.

[0007] Furthermore, a rolling adjustment mechanism is configured between two adjacent sets of conveying rollers, the rolling adjustment mechanism including a second lifting cylinder, a roller frame and a horizontal conveying roller, the roller frame being located at the free end of the second lifting cylinder, the horizontal conveying roller being rotatably mounted on the roller frame, and the horizontal conveying roller being perpendicular to the axis of the conveying roller.

[0008] Furthermore, the fixing plate and the conveying plate are slidably disposed in the push-pull groove at intervals along the height direction of the positioning plate. The positioning plate is provided with a drive cavity, and the drive cavity is provided with a drive motor and multiple sets of drive components. The output shaft of the drive motor is connected to one of the drive components.

[0009] Furthermore, the drive assembly includes a sector gear, a drive gear, a drive disk, and a connecting rod. The sector gear is rotatably mounted on the side wall of the drive cavity via a rotating shaft. The drive gear is rotatably mounted on the side wall of the drive cavity via a drive shaft. Two sets of drive gears are symmetrically arranged on both sides of the sector gear. The drive disk is fixedly mounted on the drive shaft and is arranged correspondingly to the drive gear. One end of the connecting rod is hinged to the drive disk. The other end of one set of drive disks is hinged to a fixed plate, and the other end of the other set of drive disks is hinged to a conveyor plate. Multiple sets of drive assemblies are respectively connected to multiple sets of fixed plates and conveyor plates. The output shaft of the drive motor and the rotating shaft of one set of drive assemblies are respectively provided with pulleys. The rotating shafts of two adjacent sets of drive assemblies are respectively provided with pulleys. Both sets of pulleys are connected by a belt drive.

[0010] Furthermore, the drive components are symmetrically arranged at both ends of the drive cavity, and the rotating shafts of the symmetrically arranged drive components are connected. The symmetrically arranged drive components are connected to the same set of fixed plates and conveyor plates.

[0011] Furthermore, the fixed positioning plate is provided with a sliding lifting plate, the lifting plate is provided with a support column, the support column is provided with an mounting plate, the mounting plate is provided with a telescopic cylinder, and the movable positioning plate is connected to the free end of the telescopic cylinder.

[0012] Furthermore, a spacing adjustment mechanism is provided below the roller conveyor line. The spacing adjustment mechanism includes a support plate, a spacing adjustment motor, a spacing adjustment screw, a spacing adjustment slide rod, and a support base. The spacing adjustment screw is rotatably mounted on the support plate. The spacing adjustment motor and the spacing adjustment slide rod are both fixedly mounted on the support plate. One end of the spacing adjustment screw is connected to the output shaft of the spacing adjustment motor. The support base is connected to both ends of the spacing adjustment screw by threads and is slidably mounted on the spacing adjustment slide rod. Two sets of symmetrical clamps are respectively mounted on two sets of support bases.

[0013] The technical solution provided by this invention has the following beneficial effects: 1. This invention uses an adjustable clamping structure to simultaneously accommodate the assembly and welding of H-beam and box-shaped steel components: the symmetrical spacing of the clamps is adjustable to adapt to H-beams and box-shaped steel with different cross-sectional dimensions; and the movable positioning plate of the clamps can achieve dual adjustment of vertical position and horizontal spacing, which can simultaneously adapt to the clamping and positioning of side plates of different sizes of H-beam and box-shaped steel components, and can drive the side plates to complete the docking with the horizontal plates.

[0014] 2. By cooperating with the push roller and the conveyor roller, the lifting height of the horizontal plates (H-beam web and box-section bottom plate) can be precisely controlled. When processing H-beam components, the horizontal plates (web) can be pushed to align with the middle of the side plates (flanges). When processing box-section steel, the lower end of the side plates (web) can be flush with the horizontal plates (bottom plate). This meets the positioning and assembly requirements of H-beam and box-section steel components for side plates and horizontal plates in different relative positions. The assembly of the two types of components can be completed without changing special equipment. Attached Figure Description

Therefore, they should not be construed as limitations on the embodiments.

[0020] See Figure 1 and Figure 2In this embodiment, the present invention provides a steel component welding and assembly machine, including a roller conveyor line, clamps 2, and push rollers 10. The roller conveyor line includes multiple sets of actively rotating conveyor rollers 1. The roller conveyor line is existing technology. The conveyor rollers 1 are driven by power to actively rotate in order to convey the steel components they carry. Its structure and working principle are existing mature technologies and will not be described in detail in this embodiment. The clamps 2 are arranged between two adjacent sets of conveyor rollers 1 and are symmetrically arranged at both ends of the conveyor rollers 1. The horizontal distance between the symmetrically arranged clamps 2 is adjustable. The position of the steel component plates is adjusted, and the plates are positioned from both sides. The horizontal spacing is adjusted to meet the positioning requirements of steel components with different cross-sectional dimensions. Multiple sets of clamps 2 are provided along the conveying direction of the roller conveyor line. These clamps 2 work together to position the plates at multiple points along their length. Each clamp 2 includes two sets of positioning plates 3: a fixed positioning plate 4 and a movable positioning plate 5. The movable positioning plate 5 is configured to have an adjustable vertical position and horizontal spacing relative to the fixed positioning plate 4. The movable positioning plate 5 and the fixed positioning plate 4 work together... The positioning plate 3 is used to clamp and position the lateral plates. Multiple sets of push-pull grooves 6 are provided on the side wall of the positioning plate 3. A fixed plate 7 and a conveying plate 8 are slidably arranged within the push-pull grooves 6. A side conveying roller 9 is rotatably mounted on the conveying plate 8. When the fixed plate 7 slides out of the positioning plate 3, the fixed plate 7 of the fixed positioning plate 4 and the movable positioning plate 5 cooperate to clamp and position the lateral plates. When the conveying plate 8 drives the side conveying roller 9 to slide out of the positioning plate 3, the side conveying roller 9 cooperates with the conveying roller 1 to convey the assembled and welded steel components. The push roller 10 is configured to be raised and lowered between two adjacent sets of conveying rollers 1. The push roller 10 corresponds to the middle of the conveying roller 1. Both the push roller 10 and the conveying roller 1 are used to support the horizontal plate. The push roller 10 is used to adjust the height of the horizontal plate relative to the side clamping plate to meet the assembly and positioning requirements of the H-shaped steel component or the box-shaped steel component. When assembling the various plates of the steel component, the horizontal plate of the steel component is placed on the conveying roller 1 and adjusted to the center position by the symmetrically arranged clamps 2. Then, the push roller 10 pushes the steel component placed horizontally on the conveying roller 1 to rise and fall, thereby realizing the adjustment of the relative height between the horizontal plate and the side plate of the H-shaped steel component.

[0021] It should be noted that multiple sets of push rollers 10 are arranged along the conveying direction of the roller conveyor line, and their lengths correspond to the length of the roller conveyor line. The lifting and lowering of the push rollers 10 are achieved by cylinder drive. The H-beam includes a web and flanges vertically arranged at both ends of the web. The box-shaped steel component includes a bottom plate, webs vertically arranged at both ends of the bottom plate, a cover plate, and stiffening ribs arranged inside it. For ease of description and understanding, in this embodiment, the plates placed horizontally on the conveying roller 1 (the web of the H-beam component and the bottom plate of the box-shaped steel component) are all referred to as horizontal plates, and the plates vertically arranged at both ends of the horizontal plates (the flanges of the H-beam component and the web of the box-shaped steel component) are all referred to as lateral plates.

[0022] In practical use, initially, the height of the push roller 10 is lower than that of the conveying roller 1, and the fixed plate 7 protrudes from the positioning plate 3. First, the horizontal plate is placed horizontally on the conveying roller 1. The symmetrical clamps 2 are driven to approach the horizontal plate from both sides, pushing it to the center position. Then, the symmetrical clamps 2 are driven to move away from each other, and the horizontal distance between the fixed positioning plate 4 and the horizontal plate is adjusted to be greater than the thickness of the lateral plate. The lateral plate is then hoisted onto the conveying roller 1, with the two sets of lateral plates located on either side of the horizontal plate. The symmetrical clamps 2 are driven to approach the two sets of lateral plates until the fixed positioning plate 4 contacts the lateral plate. The movable positioning plate 5 is driven to move horizontally away from the fixed positioning plate 4 until its vertical projection extends to the outside of the lateral plate. Then, through the vertical movement of the movable positioning plate 5, it moves to correspond with the lateral plate. The movable positioning plate 5 is then driven to move horizontally towards the lateral clamp, and the movable positioning plate 5 cooperates with the fixed positioning plate 4 to clamp the lateral clamp. The subsequent work process differs depending on the welding and assembly of the H-shaped or box-shaped steel components. It is important to note that the vertical movement distance of the movable positioning plate 5 is related to the welding position of the horizontal and side plates. The principle is that the clamping position of the movable positioning plate 5 should not affect the welding position. For example, when machining H-shaped steel components, since the welding position of the horizontal and side plates is located in the middle of the side plates, the vertical downward movement distance of the movable positioning plate 5 is slightly shorter, clamping only the upper part of the side plates.

[0023] When assembling H-beam steel components by welding: The push roller 10 is driven to rise, and the push roller 10 contacts the horizontal plate and drives the horizontal plate to rise until it corresponds to the middle of the side plate. At this time, the symmetrical clamp 2 is driven to move the two sets of side plates (flange plates) from both sides to approach the horizontal plate (web plate), thus realizing the assembly of the side plates and the horizontal plate. Then, the joint is welded.

[0024] When assembling box-type steel components by welding: With the horizontal plate held in place by the symmetrical clamp 2, stiffening ribs are welded onto the horizontal plate. The symmetrical clamp 2 is driven to move two sets of lateral plates (web plates) from both sides towards the horizontal plate (bottom plate), thus assembling the lateral and horizontal plates. The joints are then welded. After welding the lateral and horizontal plates, the movable positioning plate 5 is moved horizontally away from the lateral plates and vertically until its lowest point is higher than the top of the lateral plates. The symmetrical clamp 2 is then moved away from the welded steel component, and another set of horizontal plates (cover plates) is hoisted above the welded steel component. The symmetrical clamp 2 is then moved closer to the steel component and the upper horizontal plate, pushing the upper horizontal plate until it is fully aligned with the welded steel component. The upper horizontal plate is then welded. During welding, the fixed positioning plate 4 can be bypassed initially for later welding, or the fixed positioning plate 4 can be temporarily moved away for welding.

[0025] During the above process, both the fixed positioning plate 4 and the movable positioning plate 5 clamp and position each plate through the fixed plate 7 on them. After the welding action is completed, the fixed plate 7 is driven to retract, and the conveying plate 8 moves outward and protrudes from the positioning plate 3. For H-beam steel components, the side conveying rollers 9 on both the fixed positioning plate 4 and the movable positioning plate 5 are in contact with the side plates of the H-beam steel component; for box-shaped steel components, the side conveying rollers 9 on the fixed positioning plate 4 are in contact with the side plates of the box-shaped steel component. The assembled and welded steel components are conveyed by the active rotation of the conveying roller 1, and are also conveyed by the side conveying rollers 9.

[0026] See Figure 2 In this embodiment, the clamp 2 also includes a first lifting cylinder 11. The fixed positioning plate 4 is located at the free end of the first lifting cylinder 11. The lower end of the fixed positioning plate 4 near the movable positioning plate 5 is provided with a support plate 12. The support plate 12 is used to support the side plate and adjust the relative height between the lower end of the side plate and the conveying roller 1 by lifting and lowering to avoid direct contact between the lower end of the side plate and the conveying roller 1. When adjusting the position of the side plate along the axial direction of the conveying roller 1, friction is generated between its lower surface and the conveying roller 1.

[0027] In practical use, initially, the upper surface of the support plate 12 is lower than the upper surface of the conveyor roller 1. The lateral plates are hoisted onto the conveyor roller 1, with two sets of lateral plates positioned on either side of the horizontal plate, directly contacting the conveyor roller 1. The symmetrical clamps 2 are driven to approach the lateral plates from both sides until the support plate 12 moves below the lateral plates. Under the action of the first lifting cylinder 11, the fixed positioning plate 4 rises, bringing the support plate 12 into contact with the lower end of the lateral plates, thus supporting them. Then, the movable positioning plate 5 cooperates with the fixed positioning plate 4 to clamp and position the lateral plates. The first lifting cylinder 11 continues to drive the fixed positioning plate 4 upwards, raising the lateral plates until their lower ends are higher than the conveyor roller 1. Afterwards, when the clamps 2 move the lateral plates closer to the horizontal plate, friction between the lateral plates and the conveyor roller 1 is avoided. When the lateral plate moves to near the horizontal plate, the first lifting cylinder 11 retracts, causing the lateral plate to descend until the lower end of the lateral plate contacts the conveying roller 1.

[0028] See Figure 3 In this embodiment, a rolling adjustment mechanism 13 is provided between two adjacent sets of conveying rollers 1. The rolling adjustment mechanism 13 includes a second lifting cylinder 14, a roller frame 15 and a horizontal conveying roller 16. The roller frame 15 is located at the free end of the second lifting cylinder 14, and the horizontal conveying roller 16 is rotatably mounted on the roller frame 15. The horizontal conveying roller 16 is perpendicular to the axis of the conveying roller 1.

[0029] In practical use, when the horizontal plate is placed on the conveyor roller 1, the second lifting cylinder 14 drives the roller frame 15 to move upward, and the horizontal conveyor roller 16 contacts the lower surface of the horizontal plate, pushing the horizontal plate upward away from the conveyor roller 1. At this time, the position of the horizontal plate is adjusted by the symmetrical clamps 2. During this adjustment process, the horizontal conveyor roller 16 rolls to prevent the horizontal plate from sliding along the axis of the conveyor roller 1 and generating friction. After the horizontal plate is centered and adjusted, the second lifting cylinder 14 drives the roller frame 15 and the horizontal conveyor roller 16 to fall, and the horizontal plate is placed back on the conveyor roller 1.

[0030] It should be noted that the rolling adjustment mechanism 13 and the clamp 2 are arranged between different conveying rollers 1, and the clamp 2 is symmetrically arranged on both sides of the push roller 10.

[0031] By setting up the support plate 12 and the rolling adjustment mechanism 13 in the above embodiments, sliding friction is avoided when the plate is adjusted on the conveying roller 1, and the plate positioning misalignment, wear and deformation caused by friction are avoided.

[0032] See Figure 4 and 5In this embodiment, the fixed plate 7 and the conveying plate 8 are slidably disposed in the push-pull groove 6 at intervals along the height direction of the positioning plate 3. The positioning plate 3 is provided with a drive cavity 17, and the drive cavity 17 is provided with a drive motor 18 and multiple sets of drive components. The output shaft of the drive motor 18 is connected to one of the drive components.

[0033] See Figure 4 and 5 In this embodiment, the drive assembly includes a sector gear 19, a drive gear 20, a drive disk 21, and a connecting rod 22. The sector gear 19 is rotatably mounted on the side wall of the drive cavity 17 via a rotating shaft 23. The drive gear 20 is rotatably mounted on the side wall of the drive cavity 17 via a drive shaft 24. Two sets of drive gears 20 are symmetrically arranged on both sides of the sector gear 19. During rotation, the sector gear 19 alternately meshes with the corresponding drive gear 20. The drive disk 21 is fixedly mounted on the drive shaft 24 and is arranged correspondingly to the drive gear 20. One end of the connecting rod 22 is hinged to the drive disk 21. The other end of one set of drive disks 21 is hinged to the fixed plate 7, and the other end of the other set of drive disks 21 is hinged to the conveying plate 8. Multiple sets of drive assemblies are respectively connected to multiple sets of fixed plates 7 and conveying plates 8. The output shaft of the drive motor 18 is provided with pulleys corresponding to the rotating shaft 23 of one set of drive assemblies. Pulleys are provided on the rotating shaft 23 of two adjacent sets of drive assemblies. Both sets of pulleys are connected by a belt 25.

[0034] See Figure 4 and 5 In this embodiment, the drive components are symmetrically arranged at both ends of the drive cavity 17, and the rotating shafts 23 of the symmetrically arranged drive components are connected. The symmetrically arranged drive components are connected to the same set of fixed plates 7 and conveying plates 8. The push-pull drive stability of the fixed plates 7 or conveying plates 8 can be guaranteed by the symmetrically arranged drive components.

[0035] In practical use, the drive motor 18 is started, and the sector gear 19 is driven to rotate under the transmission action of the belt 25. The sector gear 19 alternately meshes with two sets of drive gears 20. The meshing drive gears 20 drive the drive disc 21 on them to rotate through the drive shaft 24. The drive disc 21 drives the fixed plate 7 or the conveyor plate 8 connected to it to slide in the push-pull groove 6 through the connecting rod 22. The position of the fixed plate 7 and the conveyor plate 8 in the push-pull groove 6 can be adjusted by the meshing of the sector gear 19 with the two sets of drive gears 20. When the fixed plate 7 slides out of the positioning plate 3 from the push-pull groove 6, the plate is fixedly positioned. When the conveyor plate 8 slides out of the positioning plate 3 from the push-pull groove 6, the steel component is conveyed by the side conveyor roller 9 in conjunction with the conveyor roller 1.

[0036] See Figure 4 and Figure 6In this embodiment, a lifting plate 26 is slidably provided inside the fixed positioning plate 4, a support column 27 is provided on the lifting plate 26, an mounting plate 28 is provided on the support column 27, and a telescopic cylinder 29 is provided on the mounting plate 28. The movable positioning plate 5 is connected to the free end of the telescopic cylinder 29.

[0037] In practical use, by driving the lifting plate 26 to slide and rise within the fixed positioning plate 4, the mounting plate 28 and the movable positioning plate 5 can be raised and lowered via the support column 27, thereby achieving vertical position adjustment of the movable positioning plate 5 relative to the fixed positioning plate 4; and the horizontal distance between the movable positioning plate 5 and the fixed positioning plate 4 can be adjusted via the telescopic cylinder 29. As a specific embodiment, the fixed positioning plate 4 is equipped with a lifting motor, a lifting screw is rotatably mounted within the fixed positioning plate 4, and a lifting slide rod is fixedly mounted thereon. The lifting screw is connected to the output shaft of the lifting motor, and the lifting plate 26 is connected to the lifting screw via a thread, slidingly mounted on the lifting slide rod. When the lifting motor is started, it drives the lifting screw to rotate, and under the drive of the lifting screw and the guidance of the lifting slide rod, the lifting plate 26 can be driven to rise and fall within the fixed positioning plate 4.

[0038] See Figure 2 In this embodiment, a spacing adjustment mechanism 30 is provided below the roller conveyor line. The spacing adjustment mechanism 30 includes a support plate 31, a spacing adjustment motor 32, a spacing adjustment screw 33, a spacing adjustment slide bar 34, and a support base 35. The spacing adjustment screw 33 is rotatably mounted on the support plate 31. The spacing adjustment motor 32 and the spacing adjustment slide bar 34 are both fixedly mounted on the support plate 31. One end of the spacing adjustment screw 33 is connected to the output shaft of the spacing adjustment motor 32. The support base 35 is connected to both ends of the spacing adjustment screw 33 by threads and is slidably mounted on the spacing adjustment slide bar 34. Two sets of symmetrical clamps 2 are respectively mounted on two sets of support bases 35.

[0039] In practical use, the spacing between the two sets of support seats 35 is adjusted by the drive of the spacing adjustment screw 33 and the guidance of the spacing adjustment slide 34, thereby adjusting the spacing between the two sets of symmetrical clamps 2. When the two sets of symmetrical clamps 2 are close to each other, the position of the plates between them is adjusted and positioned.
