Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a laser-arc hybrid welding device. Background Technology

[0002] In laser-arc hybrid welding technology, the angle adjustment between the laser welding head and the arc welding head is crucial for welding quality and efficiency. Existing laser welding heads typically have a fixed angle, which limits the welding range and fails to meet the welding requirements of complex workpieces. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a laser-arc hybrid welding device.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a laser-arc hybrid welding device, including a base plate, a mounting platform set on the base plate, and a mounting plate set on the mounting platform. A semi-circular adjusting disk is rotatably provided on the mounting plate, a mounting frame is provided on the semi-circular adjusting disk, a laser welding head is provided on the mounting frame, and a locking mechanism for locking the semi-circular adjusting disk is also provided on the semi-circular adjusting disk. A rotating mechanism is provided on the mounting plate below the semi-circular adjusting disk, and an arc welding head is provided on the rotating mechanism. The rotating mechanism is used to drive the arc welding head to rotate, so as to adjust the angle between the arc welding head and the laser welding head.

[0005] As a preferred embodiment, the mounting plate is equipped with a support plate, and the semi-circular adjusting disc is rotatably mounted on the support plate. The locking mechanism includes an arc-shaped moving groove on the semi-circular adjusting disc, and a first locking screw that passes through and slides into the arc-shaped moving groove on the support plate. A first clamping block is fixedly mounted on the first locking screw. Through the cooperation of the first locking screw and the arc-shaped moving groove, the semi-circular adjusting disc can be firmly locked after the angle is adjusted, ensuring the stability of the laser welding head during the welding process.

[0006] As a preferred embodiment, the semi-circular adjusting disc is provided with an arc-shaped limiting groove, and the support plate is provided with a first guide bolt that passes through the arc-shaped limiting groove and slides in cooperation with it. The first guide bolt slides within the arc-shaped limiting groove, which can limit the movement trajectory of the semi-circular adjusting disc, making it more stable when adjusting the angle and avoiding shaking or deviation.

[0007] As a preferred embodiment, a roller is rotatably mounted on the support plate, and the roller has an annular groove that mates with the semi-circular adjusting disc. The roller reduces the friction when the semi-circular adjusting disc rotates, making the adjustment process smoother. At the same time, the engagement of the annular groove with the semi-circular adjusting disc further enhances the stability of the semi-circular adjusting disc during rotation.

[0008] As a preferred embodiment, the mounting bracket includes two side plates, with the laser welding head located between the two side plates and fixed plates on both sides. A horizontal plate for supporting the fixed plates is located at the lower end of each side plate. A strip-shaped adjustment hole is provided on the side plate, and a second locking screw is provided on the fixed plate, passing through and slidingly engaging with the strip-shaped adjustment hole. A second clamping block is fixedly mounted on the second locking screw. By adjusting the position of the second locking screw within the strip-shaped adjustment hole, fine-tuning of the laser welding head in the horizontal direction can be achieved for better alignment with the welding position of the workpiece.

[0009] As a preferred embodiment, the fixing plate is provided with an oblong guide hole, and the fixing plate is provided with a second guide bolt that passes through the oblong guide hole and slides in fit with the oblong guide hole. The second guide bolt slides within the oblong guide hole, providing guidance for the horizontal fine adjustment of the laser welding head and ensuring the accuracy of the adjustment.

[0010] As a preferred embodiment, the rotating mechanism includes a fixed frame, a drive motor mounted on the fixed frame, and a mounting plate disposed at the end of the output shaft of the drive motor. The arc welding head is mounted on the mounting plate. The drive motor drives the mounting plate to rotate, thereby realizing the rotation of the arc welding head and facilitating quick and easy adjustment of the angle between the arc welding head and the laser welding head.

[0011] As a preferred embodiment, the mounting platform includes a horizontal moving module and a robotic arm mounted on the horizontal moving module. The mounting plate is mounted on the robotic arm, which is used to drive the mounting plate to move in both vertical and horizontal directions.

[0012] As a preferred embodiment, the robotic arm includes a vertical movement module and a horizontal movement module, wherein the vertical movement module is arranged in a vertical direction and the horizontal movement module is arranged in a direction perpendicular to the vertical movement module.

[0013] The beneficial effects of this application are as follows:

[0014] 1. By setting a semi-circular adjustment disk and a rotating mechanism, the present invention can easily adjust the relative position and angle between the laser welding head and the arc welding head, so that the two welding methods can work together better and improve welding quality and efficiency.

[0015] 2. The strip-shaped adjustment holes and waist-shaped guide holes on the mounting bracket enable fine-tuning of the laser welding head in the horizontal direction, further improving the welding precision.

[0016] 3. The multiple movable modules of the mounting platform enable the welding device to flexibly adapt to welding parts of different shapes and sizes, enhancing the device's versatility and adaptability to meet diverse production needs. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] Please see Figure 1-4This utility model provides a laser-arc hybrid welding device, comprising a base plate 1, a mounting platform 2 mounted on the base plate 1, and a mounting plate 3 mounted on the mounting platform 2. A semi-circular adjusting disk 4 is rotatably mounted on the mounting plate 3, and a mounting frame is mounted on the semi-circular adjusting disk 4. A laser welding head 6 is mounted on the mounting frame. The semi-circular adjusting disk 4 is also provided with a locking mechanism for locking the semi-circular adjusting disk 4. A rotating mechanism 7 is provided on the mounting plate 3 below the semi-circular adjusting disk 4. An arc welding head 8 is mounted on the rotating mechanism 7. The rotating mechanism 7 is used to drive the arc welding head 8 to rotate, so as to adjust the angle between the arc welding head 8 and the laser welding head 6.

[0024] The mounting plate 3 is equipped with a support plate 9, and a semi-circular adjusting disc 4 is rotatably mounted on the support plate 9. The locking mechanism includes an arc-shaped moving groove 41 on the semi-circular adjusting disc 4, and a first locking screw 42 on the support plate 9 that penetrates and slides through the arc-shaped moving groove 41. The first locking screw 42 is threadedly connected to the support plate 9, and a first pressing block 421 is fixedly mounted on the first locking screw 42. The semi-circular adjusting disc 4 is equipped with an arc-shaped limiting groove 43, and the support plate 9 is equipped with a first guide bolt 431 that penetrates and slides through the arc-shaped limiting groove 43. The first guide bolt 431 is threadedly connected to the support plate 9. The length of the arc-shaped moving groove 41 is greater than the length of the arc-shaped limiting groove 43. The rear end of the laser welding head 6 is used to connect a laser cable. The support plate 9 has a third clearance hole for the laser cable to pass through, the mounting plate 3 has a first clearance hole 31 for the laser cable to pass through, and the semi-circular adjusting disc 4 has a second clearance hole 44 for the laser cable to pass through. There are four arc-shaped limiting grooves 43, arranged in pairs. The two sets of arc-shaped limiting grooves 43 are located on both sides of the second clearance hole 44. The concave surface of the arc-shaped limiting groove 43 faces the second clearance hole 44. The second clearance hole 44 is located above the arc-shaped moving groove 41, and the concave surface of the arc-shaped moving groove 41 faces the second clearance hole 44.

[0025] When the angle of the semi-circular adjusting disc 4 needs to be adjusted, rotating the first clamping block 421 drives the first locking screw 42 to rotate, causing the first clamping block 421 to move away from the semi-circular adjusting disc 4, allowing the semi-circular adjusting disc 4 to rotate. After adjusting to the appropriate angle, rotating the first clamping block 421 drives the first locking screw 42 to rotate, causing the first clamping block 421 to contact the semi-circular adjusting disc 4, thereby pressing and fixing the semi-circular adjusting disc 4 to ensure the stability of the laser welding head 6 during the welding process. In addition, the first guide bolt 431 slides within the arc-shaped limiting groove 43, which can limit the movement trajectory of the semi-circular adjusting disc 4, making it more stable when adjusting the angle and avoiding shaking or displacement.

[0026] The support plate 9 is rotatably equipped with a roller 91, and the roller 91 has an annular groove 92 that cooperates with the semi-circular adjustment disk 4. The roller 91 can reduce the friction when the semi-circular adjustment disk 4 rotates, making the adjustment process smoother. At the same time, the cooperation between the annular groove 92 and the semi-circular adjustment disk 4 further enhances the stability of the semi-circular adjustment disk 4 when it rotates.

[0027] Specifically, the mounting bracket includes two side plates 5, with the laser welding head 6 located between the two side plates 5 and fixed plates 61 on both sides. A horizontal plate 54 supporting the fixed plates 61 is located at the lower end of each side plate 5. A strip-shaped adjustment hole 51 is provided on each side plate 5, and a second locking screw 52 passes through and slides into the strip-shaped adjustment hole 51 on each fixed plate 61. The second locking screw 52 is threadedly connected to the fixed plate 61, and a second clamping block 521 is fixedly mounted on the second locking screw 52. By rotating the second clamping block 521, the second locking screw 52 rotates, causing the second clamping block 521 to move away from the side plate 5, i.e., not contacting it. This allows the fixed plate 61 to slide along the length of the strip-shaped adjustment hole 51, thus enabling fine-tuning of the laser welding head 6 in the horizontal direction. After adjustment, rotating the second clamping block 521 rotates the second locking screw 52, ​​causing the second clamping block 521 to contact the side plate 5, fixing the fixed plate 61 in place. Meanwhile, the fixing plate 61 is provided with a waist-shaped guide hole 53, and the fixing plate 61 is provided with a second guide bolt 531 that passes through the waist-shaped guide hole 53 and slides in cooperation with the waist-shaped guide hole 53. The second guide bolt 531 is threadedly connected to the fixing plate 61, and the second guide bolt 531 slides in the waist-shaped guide hole 53 to provide guidance for the horizontal fine adjustment of the laser welding head 6 and ensure the accuracy of the adjustment.

[0028] Combination Figure 1 and Figure 4 As shown, the rotating mechanism 7 includes a fixed frame 71, a drive motor 72 mounted on the fixed frame 71, and a mounting plate 73 mounted on the output shaft end of the drive motor 72. The arc welding head 8 is mounted on the mounting plate 73. The fixed frame 71 is bolted to the mounting plate 3. It should be noted that any parts not described in detail in this application are prior art.

[0029] Furthermore, the mounting platform 2 includes a horizontal moving module 21 and a robotic arm mounted on the horizontal moving module 21. The mounting plate 3 is mounted on the robotic arm, which drives the mounting plate 3 to move vertically and horizontally. The robotic arm includes a vertical moving module 22 and a horizontal moving module 23. The vertical moving module 22 is arranged vertically, and the horizontal moving module 23 is arranged perpendicular to the vertical moving module 22. The horizontal moving module 21, vertical moving module 22, and horizontal moving module 23 can all use the same module, which typically includes a horizontally extending slide rail on which a motor-driven slide table is mounted. Alternatively, the horizontal moving module 21, vertical moving module 22, and horizontal moving module 23 can also use existing ball screw modules, which are prior art and will not be described in detail here.

[0030] Of course, this utility model is not limited to the embodiments described above. Several other embodiments based on the design concept of this utility model are also provided below.

[0031] For example, in other embodiments, unlike the embodiments described above, a control unit is also included. The control unit includes a PLC controller, which is electrically connected to the drive motor 72, the horizontal movement module 21, the vertical movement module 22, and the lateral movement module 23, respectively.

[0032] For example, in other embodiments, unlike the embodiments described above, the roller 91 is made of a wear-resistant material, which is rubber.

[0033] For example, in other embodiments, unlike the embodiments described above, the laser welding head is a field lens laser head, and the oscillation amplitude of the field lens laser head is greater than that of a conventional laser head. The field lens laser welding head, in conjunction with the semi-circular adjustment disk, the rotation mechanism, and the arc welding head 8, can achieve a better energy coupling result.
