Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] The purpose of this invention is to provide a welding robot for intelligent welding, which solves the problems existing in the prior art. It has a simple structure, is easy to use, effectively expands the scope of application, and effectively improves welding accuracy.
[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] This utility model provides a welding robot for intelligent welding, such as... Figures 1-5As shown, the device includes: a mounting base 1, a rotating mounting plate 2, a positioning arm 3, a swing arm 4, a mounting frame, a surround angle adjustment mechanism 6, a lateral thrust adjustment mechanism 8, and a welding head 9. The rotating mounting plate 2 is mounted on the mounting base 1 and can rotate horizontally and maintain its rotated position. The positioning arm 3 is mounted on the rotating mounting plate 2. One end of the swing arm 4 is rotatably connected to the end of the positioning arm 3 away from the rotating mounting plate 2 in the vertical direction and can maintain its rotated position. The mounting frame is fixedly connected to the end of the swing arm 4 away from the positioning arm 3. The surround angle adjustment mechanism 6 includes a first arc-shaped guide rail, a second arc-shaped guide rail 601, and a square mounting frame 7. The first and second arc-shaped guide rails 601 are arranged parallel to each other and are respectively fixed to both ends of the mounting frame. The two ends of the square mounting frame 7 in the length direction are respectively connected to the first and second arc-shaped guide rails. The rail 601 is slidably connected and can maintain its position after sliding. The lateral propulsion adjustment mechanism 8 includes a swing adjustment block 801, a propulsion telescopic rod 803, and a positioning bracket 804. The swing adjustment block 801 is rotatably connected to the square mounting frame 7 and can maintain its position after rotation. The rotation direction of the swing adjustment block 801 is perpendicular to the length direction of the square mounting frame 7. The fixed end of the propulsion telescopic rod 803 is vertically fixedly connected to the swing adjustment block 801, and the telescopic end of the swing adjustment block 801 is fixedly connected to the positioning bracket 804. The welding head 9 is installed on the positioning bracket 804. This design allows the welding robot to adjust its overall working position on the horizontal plane, expanding the working area and flexibly aligning welding points at different positions. It eliminates the need for manual large-scale movement of the entire device, improving ease of use and work efficiency. The positioning arm 3 provides a stable support foundation for subsequent connected components such as the swing arm 4, ensuring the stability of the entire robot structure. This ensures that the accuracy will not decrease due to instability of the foundation when the swing arm 4 and subsequent components move, thus improving the overall stability of the welding robot's operation. The mounting frame provides a fixed carrier for the subsequent installation of components such as the circumferential angle adjustment mechanism 6, ensuring the stable installation and operation of the circumferential angle adjustment mechanism 6 and enabling the effective realization of the circumferential angle adjustment function, thereby helping to improve the stability of the multi-angle adjustment of the welding head 9. The square mounting frame 7 slides and maintains its position on the parallel arc-shaped guide rail, allowing the welding head 9 to adjust its angle in the circumferential direction, greatly expanding the spatial angle range that the welding head 9 can cover, enabling the welding robot to better adapt to the needs of complex welding trajectories and flexibly handle the welding of various complex-shaped workpieces such as arcs and rings. The swing adjustment block 801 can rotate and maintain its position, enabling fine-tuning of the angle of the welding head 9 in the lateral direction. Combined with the circumferential angle adjustment function of the welding head 9, it further improves the flexibility and accuracy of the angle adjustment of the welding head 9. The push telescopic rod 803 can push the welding head 9 closer to or further away from the welding point, ensuring a suitable distance between the welding head 9 and the workpiece, better meeting the welding distance requirements of different welding processes, and helping to ensure welding quality.
[0026] In a preferred embodiment, the mounting bracket is a U-shaped mounting bracket 5. The middle part of the U-shaped mounting bracket 5 is fixedly connected to the end of the swing arm 4 away from the positioning arm 3. The first arc-shaped guide rail and the second arc-shaped guide rail 601 are fixedly connected to the U-shaped mounting bracket 5 respectively. The structural design of the U-shaped mounting bracket facilitates the installation and fixing of the arc-shaped guide rail of the surround angle adjustment mechanism 6, thereby improving structural stability. On the other hand, the U-shaped structure provides better accommodation space for components such as the surround angle adjustment mechanism 6, making the overall mechanism layout more compact and reasonable. This is conducive to the miniaturization and integration of the overall mechanical structure and facilitates the installation and use of the equipment in different working environments.
[0027] In a preferred embodiment, the surround angle adjustment mechanism 6 further includes a first limiting slider 603, a second limiting slider, a first extension mounting plate 604, a second extension mounting plate, a first servo motor 605, a first arc-shaped external gear block, and a first rolling gear 606. A first arc-shaped groove is provided on the side of the first arc-shaped guide rail near the second arc-shaped guide rail 601, and a second arc-shaped groove is provided on the side of the second arc-shaped guide rail 601 near the first arc-shaped guide rail. The first limiting slider 603 is slidably connected to the first arc-shaped groove and fixedly connected to one end of the first extension mounting plate 604. The servo motor is mounted on the other end of the first extension mounting plate 604, and the output shaft of the servo motor is connected to the first... A rolling gear 606 is fixedly connected, and a first arc-shaped external toothed block is fixedly connected to the outside of the first arc-shaped guide rail and meshes with the first rolling gear 606. A second limiting slider is slidably connected to the second arc-shaped slide groove and fixedly connected to one end of the second extended mounting plate. The middle part of the first extended mounting plate 604 is fixedly connected to one end of the square mounting frame 7, and the middle part of the second extended mounting plate is fixedly connected to the other end of the square mounting frame 7. The rolling gear is driven by a servo motor to mesh with the arc-shaped external toothed block, and the limiting slider slides in the arc-shaped slide groove, realizing the stable and precise circumferential sliding of the square mounting frame 7 along the arc-shaped guide rail, thereby driving the welding head 9 to perform precise circumferential angle adjustment. At the same time, the double-sided symmetrical structural design further enhances the stability of the movement and the accuracy of the adjustment, ensuring the positional and angular accuracy of the welding head 9 during the circumferential adjustment process, and improving the welding quality and efficiency.
[0028] In a preferred embodiment, the surround angle adjustment mechanism 6 further includes a second servo motor, a second arc-shaped external gear block 602, and a second rolling gear. The second servo motor is mounted on the end of the second extended mounting plate away from the second limiting slider. The output shaft of the second servo motor is fixedly connected to the second rolling gear. The second arc-shaped external gear block 602 is fixedly connected to the outside of the second arc-shaped guide rail 601. The second rolling gear meshes with the second arc-shaped external gear block 602. The dual-sided servo motor drive structure makes the force on both sides of the square mounting frame 7 more even during the surround motion, and can better maintain a stable circular motion trajectory. Compared with single-sided drive, dual-sided drive enhances the power and reliability of the entire surround angle adjustment mechanism 6, reduces the motion deviation caused by uneven force on one side, and further improves the accuracy and stability of the surround angle adjustment of the welding head 9, ensuring precise operation in various complex welding tasks.
[0029] In a preferred embodiment, the lateral propulsion adjustment mechanism 8 further includes a first rotary motor, which is installed in a square mounting frame 7. A connecting column 802 is provided on one side of the swing adjustment block 801. The output shaft of the first rotary motor is fixedly connected to the connecting column 802. The first rotary motor provides power for the rotation of the swing adjustment block 801. By accurately transmitting power through the connecting column 802, the swing adjustment block 801 can be controlled more precisely and flexibly, thereby adjusting the angle of the welding head 9 in the lateral direction more accurately, meeting the high precision requirements of different welding processes for the lateral angle of the welding head 9, and improving welding accuracy and welding quality.
[0030] In a preferred embodiment, the telescopic rod 803 is an electrically operated telescopic rod. The telescopic rod's extension length can be precisely controlled by electrical signals, offering higher precision control and faster response compared to other types of telescopic rods. It can precisely control the distance between the welding head 9 and the workpiece according to welding process requirements and adjust it quickly, improving the efficiency and accuracy of welding operations and contributing to improved welding quality and stability.
[0031] In a preferred embodiment, the extension and retraction direction of the electric telescopic rod is perpendicular to the rotation axis of the swing adjustment block 801. This perpendicular arrangement ensures that the extension and retraction movement of the electric telescopic rod is not disturbed when the swing adjustment block 801 changes the lateral angle of the welding head 9, and vice versa. The movements in the two directions are independent yet coordinated, allowing for more accurate operation of the welding head 9 in angle adjustment and position advancement. This further improves the overall operational precision and flexibility of the welding robot, better adapting to complex and ever-changing welding needs.
[0032] In a preferred embodiment, a second rotary motor is also included. The second rotary motor is mounted on the mounting base 1, and its output shaft is fixedly connected to the center of the rotary mounting plate 2. The second rotary motor provides a more stable and controllable power source for the horizontal rotation of the rotary mounting plate 2. This allows for precise control of the rotation angle and speed of the rotary mounting plate 2, enabling more accurate horizontal positioning of the welding robot. This meets the welding needs of different workstations and workpieces in different directions, further enhancing the equipment's adaptability to complex production scenarios and improving work efficiency and welding quality.
[0033] In a preferred embodiment, the rotation of the swing arm 4 can be driven by hydraulic power or a rotary motor, etc. The fixed end of the hydraulic cylinder is installed on the positioning arm 3, and the output end is installed on the swing arm 4. The hydraulic cylinder drives the swing arm 4 to achieve the corresponding action.
[0034] The above-mentioned method of using a welding robot for intelligent welding
[0035] Overall orientation adjustment
[0036] Start the second rotary motor on the mounting base 1. Its output shaft drives the rotary mounting plate 2 to rotate. According to the position of the workpiece and the welding requirements, the rotary mounting plate 2 is rotated to a suitable horizontal angle so that the positioning arm 3 is in a position that is convenient for welding operation. The position after rotation is maintained by the control system.
[0037] Vertical angle adjustment
[0038] Depending on the height of the workpiece and the specific welding location, the swing arm 4 is manually or via the control system to rotate vertically around one end of the positioning arm 3, adjusting it to a suitable angle. After adjustment, the swing arm 4 can maintain a stable vertical position after rotation, thereby determining the height position of the welding head 9 and preparing for subsequent welding.
[0039] Surround angle adjustment
[0040] According to the welding trajectory and process requirements, the first servo motor 605 and the second servo motor in the surround angle adjustment mechanism 6 are activated.
[0041] The output shaft of the first servo motor 605 drives the first rolling gear 606 to rotate. The first rolling gear 606 meshes with the first arc-shaped external tooth block fixed on the outside of the first arc-shaped guide rail. At the same time, the first extension mounting plate 604 slides in the first arc-shaped groove of the first arc-shaped guide rail through the first limiting slider 603. As the first rolling gear 606 rotates, the first extension mounting plate 604 will make a circular motion along the arc-shaped groove.
[0042] At the same time, the output shaft of the second servo motor drives the second rolling gear to rotate. The second rolling gear meshes with the second arc-shaped outer tooth block 602 fixed on the outside of the second arc-shaped guide rail 601. The second extension mounting plate slides in the second arc-shaped groove of the second arc-shaped guide rail 601 through the second limiting slider, so that the second extension mounting plate also makes a circular motion along the corresponding arc-shaped groove.
[0043] Since the two extended mounting plates are fixedly connected to both ends of the square mounting frame 7, the square mounting frame 7 is driven to slide circumferentially along the first arc-shaped guide rail and the second arc-shaped guide rail 601, thereby adjusting the circumferential angle of the welding head 9. This allows the welding head 9 to be aligned with different welding points in the circumferential direction for welding work.
[0044] Lateral angle adjustment and propulsion
[0045] Lateral Angle Adjustment: The first rotary motor in the lateral propulsion adjustment mechanism 8 is activated. The output shaft of the first rotary motor drives the swing adjustment block 801 to rotate via the connecting column head 802. The swing adjustment block 801 rotates within the square mounting frame 7 in a direction perpendicular to the length of the square mounting frame 7, thereby adjusting the orientation angle of the welding head 9 in the lateral direction. Based on the actual requirements of the weld point in the lateral direction, the welding head 9 is adjusted to a suitable lateral angle to meet the requirements of different welding processes. For example, when welding a specific angle on the side of the workpiece is required, the lateral angle of the welding head 9 can be precisely adjusted using this method.
[0046] Advancement and Adjustment: The extension and retraction of the electric telescopic rod is controlled according to the distance between the welding head 9 and the workpiece, as well as the specific welding process requirements. The fixed end of the electric telescopic rod is vertically fixedly connected to the swing adjustment block 801. The extension end drives the positioning bracket 804 and the welding head 9 to move forward or backward in a direction perpendicular to the rotation axis of the swing adjustment block 801. This accurately advances the welding head 9 to the appropriate welding position to contact the workpiece, maintaining a suitable welding distance. For example, when welding thin plates, precise control of the distance between the welding head 9 and the plate ensures the welding effect.
[0047] Welding operation
[0048] Welding parameters (such as welding current, voltage, and welding speed, which are pre-set according to the material and thickness of the workpiece) are transmitted to the welding system. Once the welding head 9 is adjusted to the appropriate position and angle, the welding system is started, and the welding head 9 begins welding the workpiece according to the preset welding path and parameters. During the welding process, the parameters of each mechanism can be fine-tuned in real time according to the actual situation. For example, if the welding path changes, the angle and position of the welding head 9 can be readjusted to ensure smooth welding.
[0049] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
