Description

Technical Field

[0001] This invention relates to the field of steel structure production technology, and in particular to a laser processing device for steel structure production. Background Technology

[0002] Laser processing equipment for steel structure production is a precision laser welding device adapted for the industrial production of steel structures. Using a high-energy laser beam as the core welding heat source, it is mainly used for splicing, butt welding, and forming welding of various types of steel and steel components. It is primarily used for butt welding and forming welding of steel structural parts of different specifications. Compared to traditional welding, laser processing has a concentrated heat input, which can reduce welding deformation of components and is suitable for mass production or customized production of steel structures.

[0003] For example, Chinese patent CN222932010U discloses an automated welding device for steel structures, including a frame, a welding mechanism, a rotation reversing mechanism, a base plate, a traversing mechanism, and a clamping mechanism. The welding mechanism includes a laser welding machine, an electric telescopic rod, a lifting frame, a welding head, and wires. The laser welding machine and the electric telescopic rod are both installed on the top of the frame. The telescopic end of the electric telescopic rod is fixed to the lifting frame. The welding head is installed on the lifting frame and is electrically connected to the laser welding machine through wires, automatically welding the workpiece and saving manpower.

[0004] The above solution involves mounting both a laser welding machine and an electric telescopic rod on the top of the frame. The telescopic end of the electric telescopic rod is fixed to the lifting frame, and a welding head is installed on the lifting frame. The welding head is electrically connected to the laser welding machine via a wire. This solution automates welding and saves manpower. However, it still has some shortcomings that need improvement. Specifically, it lacks an independent and efficient quick-flipping adaptation structure. It relies solely on a single transmission-type rotary reversing component to complete the workpiece turning operation. The rotation adjustment speed is limited, and the workpiece cannot be quickly rotated and flipped after welding. The flipping operation process is cumbersome and time-consuming, making it difficult to continuously complete double-sided welding of components. Furthermore, the existing commercially available flipping and matching components have poor operational stability and are prone to shaking and positional deviation during operation, which affects the laser welding forming effect and makes it difficult to adapt to the actual production and processing needs of double-sided welding of steel structures. Summary of the Invention

[0005] The purpose of this invention is to provide a laser processing device for steel structure production, in order to solve the problem that there is a lack of independent and efficient rapid flipping adaptation structure, while the existing commercially available flipping and matching components have poor operational stability, are prone to shaking and positional displacement during operation, and thus affect the laser welding forming effect, making it difficult to adapt to the actual production and processing needs of double-sided welding of steel structures.

[0006] To achieve the above objectives, the present invention provides a laser processing device for steel structure production, comprising a worktable, symmetrically mounted mounting bases on the top of the worktable, a movable component installed inside the mounting bases, a movable base slidably mounted on the top of the mounting bases via the movable component, a first fixed base and a second fixed base fixedly connected to the top of the movable bases respectively, a rotating disk rotatably connected to opposite sides of the first fixed base and the second fixed base via bearings, a tilting component mounted on one side of each of the first fixed bases and the second fixed base, the tilting component comprising a motor frame, a first drive motor, a drive gear and a driven gear, a rotating base fixedly connected to one side of the rotating disk, and a first fixed base extending from the other side of the rotating base.

[0007] Furthermore, the flipping assembly also includes a plug, a connecting shaft, a sliding hole, a limiting block, and a limiting groove. The other end of the drive gear on the first fixed seat is fixedly connected to the connecting shaft. A through hole is opened on one side of the second fixed seat, and a sliding hole is opened on one side of the drive gear on the second fixed seat. The other end of the connecting shaft passes through the through hole and is slidably connected to the sliding hole. Limiting blocks are symmetrically fixedly connected to the outer wall of the connecting shaft. The limiting blocks are arranged in four groups. Limiting grooves are symmetrically opened on the inner wall of the sliding hole. The limiting blocks and the limiting grooves are slidably connected. The other end of the connecting shaft is fixedly connected to the plug.

[0008] Furthermore, the clamping assembly includes a movable hole, a movable post, a return spring, a fixed block, and a clamping block. The outer wall of the clamping ring is symmetrically provided with movable holes in a circular array, and the movable holes are arranged in four groups. The movable holes communicate with the inside of the clamping ring. A movable post is slidably connected inside the movable hole. One end of the movable post is fixedly connected to the fixed block, and the other end of the movable post extends into the fixed ring and is fixedly connected to the clamping block. The other side of the clamping block is obliquely arranged. A return spring is fixedly sleeved on the outer wall of the movable post, and the two ends of the return spring are fixedly connected to one side of the fixed block and the outer wall of the clamping ring, respectively.

[0009] Furthermore, the fixing component includes a fixing post, a threaded hole, a threaded post, a knob, and an arc-shaped clamping seat. The outer wall of the fixing ring is symmetrically fixedly connected to the fixing post through an annular circumferential array. The fixing post is arranged in three groups. One end of the fixing post has a threaded hole that communicates with the inside of the fixing ring. The threaded hole is threadedly connected to the threaded post. One end of the threaded post is fixedly connected to a knob. The other end of the threaded post extends into the inside of the fixing ring and is rotatably connected to the arc-shaped clamping seat.

[0010] Furthermore, both the clamping end of the arc-shaped clamping seat and the inclined end of the clamping block are provided with anti-slip pads, the surface of the anti-slip pads is provided with anti-slip textures, and the anti-slip pads are made of rubber.

[0011] Furthermore, the moving component includes a receiving cavity, a bidirectional lead screw, a guide rod, a moving block, a connecting block, and a second drive motor. Each assembly base has a receiving cavity inside. A bidirectional lead screw is rotatably connected to and a guide rod is fixedly connected to each receiving cavity. Moving blocks are sleeved on the outer sides of both the guide rod and the bidirectional lead screw. A second drive motor is mounted on one side of the assembly base. The output end of the second drive motor extends into the receiving cavity and is fixedly connected to the bidirectional lead screw. A connecting block is fixedly connected to the top of the moving block. The top of the connecting block extends out of the assembly base and is fixedly connected to the bottom of the moving base. The moving block is threadedly connected to the bidirectional lead screw and slidably connected to the guide rod. A through groove is formed on the top of the assembly base, communicating with the inside of the receiving cavity. The connecting block is slidably connected to the through groove.

[0012] Furthermore, each side of the assembly base is provided with a guide groove, and a guide block is fixedly connected to the side of the movable base near the assembly base. The guide block and the guide groove are slidably connected.

[0013] Furthermore, an electric push rod is installed on the top of the fixed frame, and a lifting seat is fixedly connected to the telescopic end of the electric push rod. The bottom of the lifting seat is fixedly connected to the laser welding head.

[0014] Compared with the prior art, the beneficial effects of the present invention are: Firstly, in this invention, by setting up a reasonably structured flipping component, the first drive motor drives the drive gear and driven gear to mesh and transmit power. With the precise sliding limit cooperation of the connecting shaft, the limiting block and the limiting groove, it can stably and reliably drive the rotating disk and the steel structure workpiece clamped and fixed inside to complete multi-angle flipping operations. This effectively solves the defects of traditional devices that rely on a single transmission structure, have limited rotation speed, cannot quickly and smoothly flip the workpiece, and are prone to deviation during the flipping process. The overall flipping operation is smooth and orderly, and the double-sided laser welding processing of the workpiece can be completed continuously without interruption. This greatly simplifies the flipping steps, shortens the flipping operation time, and effectively improves the overall welding processing cycle, continuously ensuring the continuity and efficiency of the welding operation.

[0015] Secondly, in this invention, the fixing component and the clamping component are combined to form an integrated dual clamping structure. The clamping component relies on the elastic force of the return spring to drive the clamping block to complete the adaptive initial elastic clamping. The fixing component adjusts the extension and retraction of the threaded column by manually rotating the knob, thereby pushing the arc-shaped clamping seat to precisely lock and secure the workpiece. The dual clamping structure works together to adapt to the positioning and fixing of steel structure workpieces of different thicknesses and specifications. The anti-slip pads bonded to the clamping end increase the friction of the contact surface, effectively improving the clamping firmness and preventing the workpiece from loosening or shifting during flipping and welding. This ensures the stability of laser welding processing accuracy, makes the weld formation more uniform and regular, improves the overall mechanical properties of the workpiece, and reduces welding deformation and processing defects.

[0016] Thirdly, in this invention, the moving components inside the mounting base drive the top moving base to move smoothly laterally. A combined transmission structure of a two-way lead screw and a guide rod achieves smooth linear movement of the moving block. Combined with the lateral guiding and limiting structure of the guide block and guide groove, it effectively prevents jamming and skew during movement. The distance between the two side fixing rings and clamping rings can be flexibly adjusted to accommodate steel structure workpieces of different lengths. Simultaneously, the worktable can slide and adjust the fixing frame, facilitating the adjustment of the laser welding processing position. The overall structure is flexible and adaptable, effectively expanding the processing application range of the device. It balances workpiece processing flexibility with production standardization, helping steel structure production achieve high-quality, stable, energy-saving, and low-consumption automated processing.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 8In this embodiment of the invention, a laser processing device for steel structure production includes a worktable 1. Assembly seats 6 are symmetrically mounted on the top of the worktable 1. A moving component 17 is installed inside the assembly seat 6. A moving seat 7 is slidably mounted on the top of the assembly seat 6 via the moving component 17. A first fixed seat 8 and a second fixed seat 9 are fixedly connected to the top of the moving seat 7. A flipping component 15 is mounted on one side of each of the first and second fixed seats 8 and 9. A rotating disk 10 is rotatably connected to the opposite sides of the first and second fixed seats 8 and 9 via bearings. A fixing ring 12 is fixedly connected to the other side of the rotating disk 10. Fixing components 19 are symmetrically mounted on the outer wall of the fixing ring 12. A clamping ring 14 is fixedly connected to the other side of the fixing ring 12 via connecting columns 13. Multiple sets of connecting columns 13 are distributed in a ring at equal intervals, and the length of each connecting column 13 is less than the minimum length threshold of the steel structure workpiece to be processed, ensuring that even short-sized workpieces can be processed. The workpiece is effectively penetrated and double-clamped by the fixed ring 12 and the clamping ring 14. The clamping ring 14 is symmetrically equipped with clamping components 21 on its outer side. The worktable 1 is slidably connected to the fixed frame 2. The bottom of the fixed frame 2 is provided with a laser welding head 5. The multi-positioning clamping structure composed of the moving component 17, the clamping component 21 and the fixed component 19, combined with the stable reversing adjustment of the flipping component 15 and the displacement-adjustable laser welding head 5, forms an integrated processing flow of workpiece positioning and clamping, position adjustment, automatic flipping and laser welding. Compared with traditional steel structure welding equipment, it effectively solves the drawbacks of traditional devices that rely on a single transmission structure to achieve workpiece turning and cannot flip smoothly and quickly. It avoids the problems of shaking and position deviation of conventional flipping components on the market. It can continuously complete double-sided welding of steel structures, greatly improve the continuity of welding processing and production efficiency, and is suitable for batch automated laser welding production of steel structure workpieces of different specifications.

[0021] Please see Figures 1 to 3The flipping assembly 15 includes a motor frame 151, a first drive motor 152, a drive gear 153, a driven gear 154, a plug 155, a connecting shaft 156, a sliding hole 157, a limiting block 158, and a limiting groove 159. A rotating seat 11 is fixedly connected to one side of the rotating disk 10. The other side of the rotating seat 11 extends to the other side of a first fixed seat 8 and a second fixed seat 9. The motor frame 151 is fixedly connected to one side of the first fixed seat 8, and the first drive motor 152 is mounted on the other side of the motor frame 151. A rotating seat 11 is fixedly sleeved on the outer side. Driven gear 154, drive gear 153 are rotatably connected to one side of the first fixed seat 8 and the second fixed seat 9, the output end of the first drive motor 152 is fixedly connected to the drive gear 153, the drive gear 153 meshes with the driven gear 154, the other end of the drive gear 153 on the first fixed seat 8 is fixedly connected to the connecting shaft 156, a through hole 16 is opened on one side of the second fixed seat 9, a sliding hole 157 is opened on one side of the drive gear 153 on the second fixed seat 9, and the other end of the connecting shaft 156 passes through the through hole 16 and connects with the sliding hole 157. 57 is a sliding connection. To ensure that the transmission does not fail when the moving seat 7 adjusts the spacing laterally, the depth of the sliding hole 157 and the effective sliding length of the connecting shaft 156 are both greater than or equal to the maximum adjustment stroke of the moving seats 7 on both sides. Limiting blocks 158 are symmetrically fixedly connected to the outer wall of the connecting shaft 156. The limiting blocks 158 are arranged in four groups. Limiting grooves 159 are symmetrically opened on the inner wall of the sliding hole 157. The limiting blocks 158 and the limiting grooves 159 are slidably connected. A plug 155 is fixedly connected to the other end of the connecting shaft 156. When the first drive motor 152 starts... After activation, the output shaft drives the drive gear 153 to rotate synchronously. The drive gear 153 and the driven gear 154 mesh with each other, thereby driving the rotating seat 11 and the rotating disk 10 to rotate as a whole. The drive gears 153 on both sides are linked by the connecting shaft 156. The limiting block 158 on the outside of the connecting shaft 156 slides and limits the movement of the limiting groove 159, ensuring the synchronization and coaxiality of the transmission on both sides, preventing deviation and jamming during the transmission process. It can accurately control the workpiece flipping angle and flipping speed, get rid of the problem of limited speed of traditional single transmission, and effectively reduce the shaking phenomenon during the flipping process.

[0022] Please see Figures 7 to 8The clamping assembly 21 includes a moving hole 211, a moving post 212, a return spring 213, a fixing block 214, and a clamping block 215. The outer wall of the clamping ring 14 has four sets of moving holes 211 symmetrically arranged in a circular array. Each moving hole 211 communicates with the interior of the clamping ring 14. A moving post 212 is slidably connected inside each moving hole 211. One end of the moving post 212 is fixedly connected to the fixing block 214, and the other end of the moving post 212 extends into the interior of the fixing ring 12 and is fixedly connected to the clamping block 215. The other side of the clamping block 215 is obliquely shaped. The outer wall of the moving post 212 is fixedly... The fixed sleeve is equipped with a return spring 213. The two ends of the return spring 213 are fixedly connected to one side of the fixed block 214 and the outer wall of the clamping ring 14, respectively. During the placement of the workpiece, the outer wall of the steel structure workpiece squeezes multiple sets of clamping blocks 215, pushes the moving column 212 to slide outward along the moving hole 211 and compresses the return spring 213. With the help of the elastic rebound force generated by the return spring 213, the clamping blocks 215 are tightly attached to the surface of the workpiece. The inclined structure of the clamping blocks 215 facilitates the quick alignment and placement of the workpiece. Multiple sets of ring-shaped clamping blocks 215 can achieve circumferential multi-point elastic contact and limit, which can adapt to steel structure workpieces with different outer diameter specifications and achieve rapid pre-clamping and positioning.

[0023] Please see Figure 6 The fixing component 19 includes a fixing post 191, a threaded hole 192, a threaded post 193, a knob 194, and an arc-shaped clamping seat 195. The outer wall of the fixing ring 12 is symmetrically fixedly connected to the fixing posts 191 through an annular circumferential array. The fixing posts 191 are arranged in three groups. One end of each fixing post 191 has a threaded hole 192, which communicates with the interior of the fixing ring 12. The threaded post 193 is threadedly connected inside the threaded hole 192. One end of the threaded post 193 is fixedly connected to the knob 194, and the other end of the threaded post 193 extends toward the fixing ring 12. An arc-shaped clamping seat 195 is rotatably connected inside. The operator can manually rotate the knob 194 to drive the threaded column 193 to move spirally inside the threaded hole 192. The threaded column 193 smoothly pushes the arc-shaped clamping seat 195 inward. Multiple sets of arc-shaped clamping seats 195 are simultaneously centered and clamp the outer wall of the steel structure workpiece. Based on the elastic pre-clamping of the clamping component 21, a rigid locking structure is formed. The clamping force can be flexibly adjusted according to the workpiece specifications. The arc-shaped structure fits the contour of the outer wall of the steel structure, and the force is evenly distributed, avoiding excessive single-point clamping pressure that may cause workpiece deformation, and further enhancing the overall fixation effect of the workpiece.

[0024] Please see Figure 8Both the clamping end of the arc-shaped clamping seat 195 and the inclined end of the clamping block 215 are provided with anti-slip pads 20. The surface of the anti-slip pads 20 is provided with anti-slip texture. The anti-slip pads 20 are made of rubber. The anti-slip pads 20 on the surface of the arc-shaped clamping seat 195 and the clamping block 215 increase the friction coefficient with the contact surface of the steel structure workpiece. The fine anti-slip texture can further improve the anti-slip limiting effect and prevent the smooth metal contact surface from sliding relative to each other under the action of flipping, twisting and welding vibration. The rubber material is soft and can buffer the clamping contact stress and prevent the steel structure surface from having indentations and wear.

[0025] Please see Figures 4 to 5 The moving assembly 17 includes a receiving cavity 171, a bidirectional lead screw 172, a guide rod 173, a moving block 174, a connecting block 175, and a second drive motor 176. Each of the mounting bases 6 has a receiving cavity 171. The bidirectional lead screw 172 is rotatably connected to each receiving cavity 171, and the guide rod 173 is fixedly connected to it. Moving blocks 174 are sleeved on the outer sides of both the guide rod 173 and the bidirectional lead screw 172. A second drive motor 176 is mounted on one side of the mounting base 6. The output end of the second drive motor 176 extends into the receiving cavity 171 and is fixedly connected to the bidirectional lead screw 172. The top of the movable block 174 is fixedly connected to a connecting block 175. The top of the connecting block 175 extends into an assembly seat 6 and is fixedly connected to the bottom of the movable seat 7. After the second drive motor 176 starts, it drives the bidirectional lead screw 172 to rotate in an directional manner. The bidirectional thread structure of the bidirectional lead screw 172 drives the two movable blocks 174 on both sides to move synchronously in opposite directions. The guide rod 173 passes through the movable block 174 to achieve lateral sliding limit. The movable block 174 drives the top movable seat 7 to move horizontally as a whole through the connecting block 175, thereby flexibly adjusting the distance between the two sets of clamping fixtures to adapt to the clamping and fixing of steel structure workpieces of different lengths.

[0026] Please see Figure 5 The movable block 174 is threadedly connected to the bidirectional lead screw 172, and the movable block 174 is slidably connected to the guide rod 173. The movable block 174 achieves power conversion by relying on the thread engagement of the bidirectional lead screw 172, converting the rotational motion of the lead screw into linear translational motion. At the same time, the movable block 174 is sleeved on the outside of the guide rod 173 for limiting sliding, restricting the rotational freedom of the movable block 174, and preventing the movable block 174 from deflecting, jamming, or shaking during the lead screw transmission process. This makes the adjustment movement of the movable seat 7 smoother and more regular, ensuring the symmetry and accuracy of the tooling spacing adjustment on both sides.

[0027] Please see Figures 4 to 5The top of the mounting base 6 is provided with a through groove 18, which communicates with the interior of the receiving cavity 171. The connecting block 175 is slidably connected to the through groove 18. The through groove 18 provides space for the lateral displacement of the connecting block 175. The connecting block 175 slides against the groove wall of the through groove 18, which can limit the vertical movement and constrain the lateral movement of the moving base 7, reduce the vertical jump and left and right sway, and prevent external debris from falling into the receiving cavity 171.

[0028] Please see Figure 1 Each side of the assembly base 6 is provided with a guide groove 23. The movable base 7 is fixedly connected to a guide block 22 on the side near the assembly base 6. The guide block 22 and the guide groove 23 are slidably connected. When the movable base 7 is adjusted and moved laterally, the guide block 22 fixed on the side slides precisely along the inside of the guide groove 23, forming an auxiliary lateral guide structure. Together with the bottom movable component 17, it forms a double upper and lower limit guide system, which effectively offsets the lateral shear force caused by the self-weight of the steel structure workpiece, welding vibration and the torsion of the overturning, prevents the movable base 7 from tilting and misaligning, and ensures that the first fixed base 8 and the second fixed base 9 always remain coaxial.

[0029] Please see Figure 1 The top of the fixed frame 2 is equipped with an electric push rod 3. The telescopic end of the electric push rod 3 is fixedly connected to a lifting seat 4. The bottom of the lifting seat 4 is fixedly connected to the laser welding head 5. The electric push rod 3 can drive the lifting seat 4 to achieve stable lifting and adjustment, thereby flexibly changing the working height of the laser welding head 5 to adapt to the welding point adjustment requirements of steel structure workpieces of different specifications. At the same time, the fixed frame 2 can slide laterally along the surface of the worktable 1, which can accurately adjust the horizontal processing position of the laser welding head 5. Combined with the workpiece flipping and lateral position adjustment structure, multi-directional position adaptation can be achieved.

[0030] The working principle of this invention is as follows: First, the steel structure workpiece to be processed is placed inside the clamping ring 14 and the fixed ring 12. The elastic thrust of the return spring 213 in the clamping assembly 21 pushes the moving column 212 and the clamping block 215 inward, forming an initial elastic limit clamping on the outer wall of the workpiece. Then, each set of knobs 194 is manually rotated, driving the threaded column 193 to spiral feed inside the threaded hole 192, driving the arc-shaped clamping seat 195 to simultaneously press against the surface of the workpiece. With the friction of the anti-slip pad 20, the workpiece is clamped securely in all directions, effectively preventing the workpiece from loosening or shifting during processing. After clamping, the second drive motor 176 is started to drive the bidirectional lead screw 172 to rotate, and the guide rod... 173. With the limiting cooperation of guide block 22 and guide groove 23, adjust the distance between the two moving seats 7 to accurately adjust the horizontal position of the workpiece to match the processing point of laser welding head 5. Then start the equipment to move the laser welding head 5 down to the working height and carry out laser welding operation on the part of the steel structure to be welded. After the single-sided welding processing of the workpiece is completed, start the first drive motor 152 in the flipping assembly 15. Through the meshing transmission of drive gear 153 and driven gear 154, and with the synchronous limiting transmission structure of connecting shaft 156, limiting block 158 and limiting groove 159, smoothly drive the rotating disk 10, fixed ring 12 and the overall clamping workpiece to flip synchronously and accurately, and quickly complete the workpiece flipping operation.
