Description
Technical Field
[0001] This invention relates to the field of automotive manufacturing technology, and in particular to a laser cutting integrated machine for intelligent heat treatment production lines for vehicle frames. Background Technology
[0002] In intelligent heat treatment production lines for vehicle frames, the integrated laser cutting machine is one of the core pieces of equipment for processing vehicle frame beams. It is primarily used for precise cutting of heat-treated vehicle frame beams, focusing on trimming burrs and excess material along the edges. Simultaneously, it separates and cuts small structural components on the frame beams to ensure dimensional accuracy and forming quality, laying the foundation for subsequent frame assembly processes. Currently, most laser cutting equipment used in the industry for vehicle frame beams possesses basic functions such as frame beam support, laser cutting, and waste material conveying. The frame beams are positioned and supported by load-bearing components, and precise cutting is achieved using a laser cutting head. Small waste materials generated during cutting fall directly onto a conveyor belt and are transported to a designated collection area. This semi-automated operation of frame beam cutting is widely used in various vehicle frame manufacturing enterprises.
[0003] However, in practical applications, existing laser cutting equipment suffers from cumbersome waste disposal and high labor costs. When cutting vehicle frame beams, the cut edges, due to their frame-like structure and large volume, cannot fall directly onto the conveyor belt like small waste pieces. Operators must manually remove the edges from the equipment, which is not only cumbersome and time-consuming but also interrupts continuous production and increases labor input. If the edges are not completely separated from the vehicle frame beam, they are prone to causing collateral damage, making manual removal very inconvenient. At the same time, existing equipment has poor adaptability and cannot flexibly adapt to vehicle frame beams of different sizes, resulting in insufficient production versatility. In addition, the cutting precision of existing equipment is insufficient. Affected by factors such as the positioning deviation of the rotating base and the movement deviation of the laser cutting head, dimensional deviations are prone to occur in the cut parts of the vehicle frame beam, which cannot meet the processing requirements of high-precision vehicle frame beams. Subsequent manual grinding and correction are required, further increasing labor intensity and production time. Therefore, this invention proposes a laser cutting integrated machine for intelligent heat treatment production lines for vehicle frames to solve the problems existing in the prior art. Summary of the Invention
[0004] To address the aforementioned issues, this invention proposes a laser cutting integrated machine for an intelligent heat treatment production line for vehicle frames. This machine achieves fully automated processing along the edge after cutting, eliminating the need for manual intervention. Furthermore, its compact design saves storage and transportation space, effectively solving the shortcomings of existing technologies such as cumbersome waste disposal and high labor costs. After laser cutting, four sets of external grippers precisely hold the four corners along the edge. A drive cylinder drives the substrate to rotate around the hinge seat, causing the outer end of the substrate to move in an arc-shaped groove. Guide wheels slide along the arc-shaped groove, ensuring smooth substrate movement. This, in turn, compresses the four corners of the edge held by the grippers inwards. The waste frame is compressed along the edge into a compact waste box. Then, by sliding a slider along the guide rod and adjusting the extension and retraction of the cylinder, the compressed waste box is transported into the compression frame. The extrusion cylinders at the four corners of the compression frame drive four sets of extrusion plates to move inward synchronously, further compressing the waste box and reducing its volume. After extrusion, the extrusion plates return to their original positions, and the processed waste box automatically falls into the waste conveyor belt below, which transports it to the designated collection area. The entire process does not require operators to manually remove the waste frame, eliminating the hassle of manual waste handling. At the same time, the volume of the compressed waste box is significantly reduced, saving storage and transportation space and lowering waste disposal costs.

The three parameters are substituted into the expression to calculate the result. and The control system is based on , The multi-axis robotic arm is driven to adjust the position of the laser cutting head, achieving real-time compensation for cutting positioning.
[0019] The beneficial effects of this invention are as follows:
[0020] 1. This invention achieves fully automated processing of the edge after cutting, requiring no manual intervention. It also saves storage and transportation space after compression, effectively solving the shortcomings of existing technologies such as cumbersome waste disposal and high labor costs. After laser cutting, four sets of external grippers precisely hold the four corners along the edge. A drive cylinder drives the substrate to rotate around the hinge seat, causing the outer end of the substrate to move in an arc along the arc groove. The guide wheel slides along the arc groove, ensuring smooth substrate movement. This, in turn, compresses the four corners of the edge held by the grippers inward, shrinking the edge into a compact waste frame. Subsequently, a slider moves along the guide rod... The sliding and adjusting cylinders extend and retract, conveying the compressed waste frame into the compression frame. The extrusion cylinders at the four corners of the compression frame drive four sets of extrusion plates to move inward synchronously, further compressing the waste frame and reducing its volume. After extrusion, the extrusion plates reset, and the processed waste frame automatically falls into the waste conveyor belt below, which transports it to the designated collection area. The entire process does not require operators to manually remove the edges, eliminating the hassle of manual waste handling. At the same time, the volume of the compressed waste frame is significantly reduced, saving storage and transportation space and lowering waste processing costs.
[0021] 2. This invention achieves complete separation of the frame edge from the vehicle frame beam, avoiding collateral damage. After the frame beam is cut along the frame edge, the equipment first uses the four corner grippers at the inner end to precisely hold the side of the frame edge, providing initial support. Then, the four sets of external grippers hold the four corners at the outer end of the frame edge. By actuating the cylinder, the grippers are pulled outward, and the tension is used to completely separate the connection between the frame edge and the vehicle frame beam, avoiding any incomplete separation and ensuring the integrity of the waste box. This facilitates subsequent compression and recycling, and eliminates the need for manual separation, further improving production efficiency.
[0022] 3. This invention has strong adaptability and can flexibly adjust the position of the gripper to adapt to the processing of frame beams of different sizes. When processing frame beams of different sizes, the fixing pin on the adjusting block can be loosened, the adjusting block can be slid along the guide rail, and the distance between the two sets of adjusting parts and the gripper on the guide rail can be adjusted. After the adjustment is completed, the fixing pin is inserted into the corresponding fixing hole to fix the adjusting block, thereby fixing the position of the gripper, so that the gripper can accurately clamp the frame beams of different widths and lengths. The entire adjustment process is simple to operate and short in time. There is no need to replace the gripper assembly or adjust the overall structure of the equipment, which greatly improves the versatility and adaptability of the equipment, reduces the equipment adjustment cost, and adapts to the processing needs of frame beams of different specifications.
[0023] 4. This invention utilizes a laser cutting positioning error compensation algorithm to correct cutting deviations in real time, significantly improving the cutting accuracy of the vehicle frame beam. This algorithm acquires the actual cutting point coordinates X1 and Y1 of the vehicle frame beam detected by the laser cutting head in real time, as well as the positioning angle deviation acquired by the angle sensor built into the rotating base. Substituting the values into the preset algorithm expression, the positioning compensation amount of the laser cutting head in the X and Y axis directions is calculated. , The control system is based on , The multi-axis robotic arm drives the laser cutting head to adjust its position, achieving real-time compensation for cutting positioning. The compensation coefficients K1-K6 in the algorithm can be flexibly adjusted according to the specifications of the vehicle frame beam and the cutting accuracy requirements. This effectively corrects the cutting errors caused by the positioning deviation of the rotating base and the movement deviation of the laser cutting head, ensuring that the laser cutting head is always aligned with the preset cutting reference point. This significantly improves the cutting dimensional accuracy of the vehicle frame beam, avoids subsequent manual grinding and correction, reduces labor intensity, and improves the consistency of vehicle frame beam processing, meeting the production needs of high-precision vehicle frame beams.

[0033] according to Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this embodiment proposes a laser cutting integrated machine for an intelligent heat treatment production line for vehicle frames. It includes a housing 1 and a waste conveyor belt 2 located below the housing 1. A rotating base 3 is rotatably mounted on one side of the housing 1, and load-bearing components are provided on both sides of the rotating base 3. The load-bearing components support the vehicle frame beam 17. A laser cutting head 4 is movably mounted on the upper inner side of the housing 1, and the laser cutting head 4 is used to laser cut the vehicle frame beam 17. The housing 1 provides overall installation support for the entire equipment, supports all core components of the equipment, and ensures the stability of the equipment operation. The waste conveyor belt... The 2-strip frame is used to receive the processed waste, enabling automatic conveying and collection of waste and preventing waste accumulation. The rotating base 3 can rotate around one side of the outer shell 1, driving the load-bearing components on both sides to switch positions, realizing alternating feeding and cutting of the frame beam 17, and improving production continuity. The load-bearing components are used to stably support the frame beam 17, ensuring that the frame beam 17 does not shake or deviate during the cutting process. The laser cutting head 4 can move flexibly and accurately align with the cutting part of the frame beam 17, using the high energy of the laser to accurately cut the burrs, excess edges and small parts of the frame beam 17, laying the foundation for subsequent waste processing and frame beam forming.
[0034] A slider 5 is movably mounted on the upper side of one side of the inner shell 1, and an operating plate 6 is mounted on one side of the slider 5. A base plate 7 is mounted at each of the four corners below the operating plate 6. The inner end of the base plate 7 is hinged to the operating plate 6, and the outer end of the base plate 7 is used for arc-shaped movement. Adjusting components are connected to both ends below the base plate 7, and grippers 8 are located below the adjusting components. The grippers 8 are used to grab and compress the scrap frame cut from the frame beam 17. A compression frame 9 is located above the scrap conveyor belt 2, and extrusion plates 10 are mounted at each of the four corners of the inner side of the compression frame 9. The four sets of extrusion plates 10 are used to further compress the compressed scrap frame. The processed scrap frame falls into the scrap conveyor belt 2. The slider 5 can move inside the outer shell 1, driving the operating plate 6 and the base plate 7, adjusting components, and grippers 8 to move together. The movement of the clamping jaws 8 allows for the transfer of the gripper frame after it has grasped the waste material frame. The operating plate 6 provides a mounting carrier for the base plate 7, ensuring that the four base plates 7 are symmetrically distributed and move in synergy. The inner end of the base plate 7 is hinged to the operating plate 6, and the outer end can move along an arc, causing the four corners of the waste material frame held by the clamping jaws 8 to retract inward, thus achieving initial compression of the waste material frame. The adjusting component is used to adjust the height and position of the clamping jaws 8 to ensure that the clamping jaws 8 accurately grasp the waste material frame. The clamping jaws 8 are used to firmly hold the cut edge frame, providing a foundation for the compression operation. The compression frame 9 provides mounting support for the extrusion plates 10. The four extrusion plates 10 move inward synchronously to perform secondary extrusion on the initially compressed waste material frame, further reducing the waste volume. After extrusion, the extrusion plates 10 are reset, and the waste material frame falls into the waste material conveyor belt 2, realizing fully automatic compression and conveying of waste material.
[0035] The upper end of the outer casing 1 is provided with a top frame 11, and both ends of one side of the outer casing 1 are provided with side guardrails 12, which are located at both ends of the load-bearing component. The top frame 11 is installed on the upper end of the outer casing 1 and can be used to install electrical control components, pipelines, etc. of the equipment. At the same time, it provides protection above the equipment to prevent dust and debris from falling into the equipment and affecting its operation. The side guardrails 12 are located at both ends of the load-bearing component to prevent the frame beam 17 from shifting or slipping on the load-bearing component, protect the stability of the frame beam 17 during the processing, and prevent operators from accidentally touching the operating parts of the equipment, thereby improving the safety of equipment operation.
[0036] The supporting assembly includes a tray 13 and support rods 14. Multiple sets of support rods 14 are provided on the tray 13, and the support rods 14 support the frame beam 17. Multiple sets of positioning seats 15 are provided on the tray 13, and positioning rods 16 are rotatably mounted on the positioning seats 15.

The positioning seats 15 are used to mount the positioning rods 16, which can rotate around the positioning seats 15. Rotating the positioning rods 16 allows them to fit against the surface of the frame beam 17, achieving precise positioning of the frame beam 17 on the tray 13, preventing displacement of the frame beam 17 during cutting, and ensuring cutting accuracy.
[0037] A side frame 18 is provided on the upper side of one side of the outer casing 1, and a threaded screw 19 is rotatably installed inside the side frame 18.

A multi-axis robotic arm 21 is provided below the moving block 20, and the laser cutting head 4 is located at the control end of the multi-axis robotic arm 21. The side frame 18 provides mounting and guiding support for the threaded screw 19 and the moving block 20, ensuring the smooth movement of the moving block 20. When the threaded screw 19 rotates, it drives the moving block 20 to move linearly along the inside of the side frame 18, driving the multi-axis robotic arm 21 and the laser cutting head 4 to move synchronously, realizing the position adjustment of the laser cutting head 4 in the X-axis direction. The multi-axis robotic arm 21 has a multi-degree-of-freedom adjustment function, which can flexibly adjust the angle and height of the laser cutting head 4, so that the laser cutting head 4 can accurately align with various cutting parts of the frame beam 17, adapt to the cutting requirements of different shapes and angles, and ensure the flexibility and accuracy of cutting.

The drive wheel on the slider 5 is adapted to the embedded groove and drives the slider 5 to move. The horizontal plate 23 is used to install the adjusting cylinder 24 and provide stable support for the adjusting cylinder 24.

The hinge seat 25 realizes the rotatable connection between the substrate 7 and the operating plate 6, and is the outer end of the substrate 7. The arc-shaped motion provides a pivot point for rotation; the guide wheel 27 is adapted to the arc-shaped groove 26. When the outer end of the substrate 7 moves along the arc, the guide wheel 27 slides along the arc-shaped groove 26, which plays a guiding and limiting role, ensuring that the substrate 7 moves smoothly and the trajectory is accurate, and preventing the substrate 7 from tilting; the hinge joint 28 is used to connect the drive cylinder 29 and the operating plate 6. The drive cylinder 29 serves as a power source and drives the substrate 7 to rotate around the hinge seat 25 through telescopic motion, thereby driving the four corners of the waste frame held by the gripper 8 to retract inward, realizing the initial compression of the waste frame.

The guide rail 30 provides a sliding guide for the adjusting block 31, facilitating the adjustment of the position of the adjusting block 31 and the gripper 8, and adapting to different sizes of waste frames. The adjusting block 31 can slide along the guide rail. The rail 30 slides to adjust the spacing between adjacent grippers 8; the lifting cylinder 32 drives the connecting seat 33, rotating rod 34, actuating cylinder 35 and grippers 8 to move up and down through telescopic movement, adjusting the height of grippers 8 to match the gripping height of the waste box; the connecting seat 33 is used to install the rotating rod 34, which rotates under the drive of the motor, driving the actuating cylinder 35 and grippers 8 to rotate, adjusting the gripping angle of grippers 8, and ensuring that grippers 8 accurately grip the waste box; the actuating cylinder 35 drives the grippers 8 to open and close through telescopic movement, realizing the gripping and release of the waste box, and at the same time can drive the grippers 8 to stretch outward, so that the waste box is completely separated from the frame beam 17.
[0041] The guide rail 30 is provided with fixing holes 36, and multiple sets of fixing holes 36 are equidistantly arranged. The adjusting block 31 is provided with fixing pins, and the fixing pins are adapted to the fixing holes 36. The multiple sets of equidistantly distributed fixing holes 36 provide multiple position selections for fixing the adjusting block 31. When the adjusting block 31 slides along the guide rail 30 to a suitable position, the fixing pin is inserted into the corresponding fixing hole 36 to fix the adjusting block 31 to the guide rail 30, thereby fixing the position of the gripper 8 and preventing the gripper 8 from shifting during the gripping and compression of the waste frame, ensuring the precise movement of the gripper 8. At the same time, it is convenient to flexibly adjust the spacing of the gripper 8 according to different sizes of the frame beam 17 and waste frame, improving the adaptability of the equipment.

The extrusion cylinder 39 serves as the power source for the extrusion plate 10. Through telescopic movement, the extrusion plate 10 is driven to move inward. The four sets of extrusion cylinders 39 move synchronously, driving the four sets of extrusion plates 10 to perform secondary extrusion on the waste box after the initial compression, further reducing the volume of waste. After the extrusion is completed, the extrusion cylinder 39 is reset, the extrusion plate 10 is separated from the waste box, and the processed waste box falls smoothly into the waste conveyor belt 2 below.

The side frame 18 provides mounting and guiding support for the threaded screw 19 and the moving block 20, ensuring the smooth movement of the moving block 20. When the threaded screw 19 rotates, it drives the moving block 20 to move linearly along the inside of the side frame 18, driving the multi-axis robotic arm 21 and the laser cutting head 4 to move synchronously, realizing the position adjustment of the laser cutting head 4 in the X-axis direction.

The three parameters are substituted into the expression to calculate the result. and The control system is based on , The multi-axis robotic arm 21 drives the laser cutting head 4 to adjust its position, achieving real-time compensation for cutting positioning.

The compensation coefficients K1-K6 can be flexibly adjusted according to the specifications of the frame beam 17 and the cutting accuracy to ensure that the laser cutting head 4 is always aligned with the preset cutting position, which greatly improves the cutting accuracy of the frame beam 17 and avoids subsequent manual correction.
[0048] This laser cutting integrated machine for intelligent heat treatment production lines for vehicle frames achieves fully automated processing along the edge after cutting, requiring no manual intervention. It also saves storage and transportation space after compression, effectively solving the shortcomings of existing technologies such as cumbersome waste disposal and high labor costs. After laser cutting, the four sets of external grippers 8 precisely hold the four corners along the edge. Driven by the drive cylinder 29, the base plate 7 rotates around the hinge seat 25, causing the outer end of the base plate 7 to move in an arc along the arc groove 26. The guide wheel 27 slides along the arc groove 26, ensuring smooth movement of the base plate 7. This, in turn, compresses the four corners along the edge held by the grippers 8 inwards, shrinking the edge into a compact waste frame. By sliding the slider 5 along the guide rod 22 and adjusting the extension and retraction of the cylinder 24, the compressed waste frame is transported into the compression frame 9. The extrusion cylinders 39 at the four corners of the compression frame 9 drive the four sets of extrusion plates 10 to move inward synchronously, extruding the compressed waste frame again to further reduce the volume of waste. After extrusion, the extrusion plates 10 are reset, and the processed waste frame automatically falls into the waste conveyor belt 2 below, which transports it to the designated collection area. The entire process does not require operators to manually remove the frame, solving the trouble of manual waste handling. At the same time, the volume of the compressed waste frame is greatly reduced, saving storage and transportation space and reducing waste processing costs. This invention achieves complete separation of the frame edge from the vehicle frame beam, avoiding collateral damage. After the frame beam is cut along the frame edge, the equipment first uses the four corner grippers 8 at the inner end to precisely hold the side of the frame edge, providing initial support. Then, the four sets of external grippers 8 hold the four corners at the outer end of the frame edge. By actuating the cylinder 35, the grippers 8 are pulled outward, and the tension is used to completely separate the connection between the frame edge and the vehicle frame beam, avoiding any uncut connection and ensuring the integrity of the waste box. This facilitates subsequent compression and recycling, and eliminates the need for manual separation, further improving production efficiency. This invention boasts strong adaptability, allowing for flexible adjustment of the gripper position to accommodate the processing of vehicle frame beams of varying sizes. When processing different sized vehicle frame beams, the fixing pin on the adjusting block 31 can be loosened, and the adjusting block 31 can be slid along the guide rail 30 to adjust the distance between the two sets of adjusting components on the guide rail 30 and the gripper 8. After adjustment, the fixing pin is inserted into the corresponding fixing hole 36 to fix the adjusting block 31, thereby fixing the position of the gripper 8. This allows the gripper 8 to accurately clamp the edges of different widths and lengths. The entire adjustment process is simple and time-saving, requiring no replacement of the gripper assembly or adjustment of the overall equipment structure, significantly improving the equipment's versatility and adaptability, reducing equipment adjustment costs, and meeting the processing needs of vehicle frame beams of different specifications. This invention utilizes a laser cutting positioning error compensation algorithm to correct cutting deviations in real time, significantly improving the cutting accuracy of vehicle frame beams. This algorithm collects the actual cutting point coordinates X1 and Y1 of the vehicle frame beam 17 detected by the laser cutting head 4 in real time, as well as the positioning angle deviation collected by the angle sensor built into the rotating base 3. Substituting the preset algorithm expression, the positioning compensation amount of the laser cutting head 4 in the X and Y axis directions is calculated. , The control system is based on , The multi-axis robotic arm 21 drives the laser cutting head 4 to adjust its position, achieving real-time compensation for cutting positioning. The compensation coefficients K1-K6 in the algorithm can be flexibly adjusted according to the specifications of the frame beam 17 and the cutting accuracy requirements. This effectively corrects the cutting errors caused by the positioning deviation of the rotating base 3 and the movement deviation of the laser cutting head 4, ensuring that the laser cutting head 4 is always aligned with the preset cutting reference point. This significantly improves the cutting dimensional accuracy of the frame beam 17, avoids subsequent manual grinding and correction, reduces labor intensity, and improves the consistency of frame beam processing, meeting the production requirements of high-precision frame beams.
