Description

Technical Field

[0001] This utility model relates to the field of laser welding, specifically to a laser online roll forming welding device. Background Technology

[0002] Laser welding technology is widely used in the field of metal sheet processing due to its advantages such as high energy density, low heat input, and fast welding speed. However, in continuous production lines, traditional laser welding equipment still faces the following technical bottlenecks: Existing equipment mostly uses fully electric modules to drive the welding torch movement. Although the accuracy is high, long-stroke X-axis positioning requires a high-power servo system, resulting in high equipment costs. Furthermore, the lack of manual fine-tuning function makes it difficult to quickly adapt to roller pressing lines of different specifications. The heat-affected zone of the sheet metal is prone to deformation after welding, and conventional equipment requires an additional shaping process, which not only reduces production efficiency but may also affect the weld quality due to secondary processing.

[0003] Therefore, it is necessary to provide a laser online roll forming welding device. Summary of the Invention

[0004] This utility model provides a laser online roll forming welding device, which effectively solves the problems of high cost and lack of roll forming in existing laser welding equipment due to the lack of manual adjustment.

[0005] The technical solution adopted by this utility model is:

[0006] A laser online roll forming welding device includes a frame and a welding mechanism mounted on the frame, and a roll forming line mounted on the frame and extending along the X-axis direction. The roll forming line is located on one side of the welding mechanism. The welding mechanism includes a first mounting frame mounted on the frame, a linear guide rail mounted on the first mounting frame along the X-axis, a slider slidably mounted on the linear guide rail, a slide block slidably connected to the linear guide rail via the slider, a slider manual clamp fixedly connected to the slide block and slidably connected to the linear guide rail, a multi-axis module mounted on the slide block, and a laser welding gun mounted at the output end of the multi-axis module.

[0007] Furthermore, the multi-axis module includes a first linear module mounted on a slide along the Y-axis, a second linear module mounted at the output end of the first linear module along the X-axis, a third linear module mounted at the output end of the second linear module along the Z-axis, an R-axis module mounted at the output end of the third linear module, and a second mounting bracket mounted on the R-axis module. The R-axis module rotates around the X-axis, and the laser welding gun is mounted on the second mounting bracket.

[0008] Furthermore: the first linear module drives the second linear module to move along the X-axis, the second linear module drives the third linear module to move along the Y-axis, the third linear module drives the R-axis module to rise and fall, and the R-axis module drives the second mounting bracket to rotate.

[0009] Furthermore, the roller pressing line includes several roller pressing mechanisms arranged on the frame along the X-axis direction. Each roller pressing mechanism includes two side supports symmetrically arranged in the Y-axis direction, a first shaft and a second shaft respectively rotatably connected to the two side supports at both ends, a first wheel coaxially fixed on the first shaft, and a second wheel coaxially fixed on the second shaft. The first shaft is located above the second shaft, and the first wheel is located above the second wheel.

[0010] Furthermore, the side support includes a stand mounted on the frame, a second plate fixedly mounted on the stand, a first sliding plate slidably and vertically connected to the stand, a guide post slidably connected to the first sliding plate and the stand and whose lower end is fixedly connected to the second plate, a first ball bearing mounted on the first sliding plate, a second ball bearing mounted on the second plate, a threaded rod threadedly connected to the stand, a chuck fixedly mounted at the lower end of the threaded rod, and a nut located above the upper surface of the stand and threadedly connected to the threaded rod. The upper end of the first sliding plate is provided with a slot that is floatingly connected to the chuck. The end of the first shaft is connected to the inner ring of the first ball bearing, and the end of the second shaft is connected to the inner ring of the second ball bearing.

[0011] Furthermore, the roller pressing mechanism also includes a connecting strip, the two ends of which are fixedly connected to the two side supports respectively.

[0012] Furthermore, the welding mechanism also includes a protective gas assembly, which includes a hose and a gas tank. The hose has an inlet and an outlet at its two ends, respectively. The hose is connected to the gas tank at the inlet end, and the hose is mounted on the multi-axis module at the other end of the inlet end.

[0013] The beneficial effects of this utility model are as follows: By setting up a linear guide rail, a slider, and a manual clamp to manually fine-tune the slide block, the cost of setting up a module for driving the slide block can be saved. This makes the entire welding mechanism easy to adapt to the length of the roller pressing line, thereby moving the laser welding gun to different positions on the roller pressing line. This ensures the shape of the product before welding and reduces deformation after welding. Attached Figure Description

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, the embodiment of this application provides a laser online roll forming welding device, the structure of which includes a frame 1 and a welding mechanism 2 disposed on the frame 1, and a roll forming line 3 disposed on the frame 1 and extending along the X-axis direction. The roll forming line 3 is located on one side of the welding mechanism 2. The welding mechanism 2 includes a first mounting frame 21 disposed on the frame 1, a linear guide rail 23 disposed on the first mounting frame 21 along the X-direction, a slider 28 slidably disposed on the linear guide rail 23, a slide block 22 slidably connected to the linear guide rail 23 through the slider 28, a slider manual clamp 24 fixedly connected to the slide block 22 and slidably connected to the linear guide rail 23, a multi-axis module 25 disposed on the slide block 22, and a laser welding gun 26 disposed at the output end of the multi-axis module 25.

[0021] In actual use, an external drive mechanism with output power drives the sheet metal to move, causing it to be rolled in the roll forming line 3. The welding mechanism 2 welds the sheet metal during the rolling process. Before welding, the slider manual clamp 24 can be released to manually push the slide block 22 to slide along the linear guide rail 23 to a predetermined position, and then the slider manual clamp 24 can be locked. The multi-axis module 25 drives the laser welding gun 26 to move to the predetermined position to weld the sheet metal rolled in the roll forming line 3.

[0022] In the above design, by setting up a linear guide rail 23, a slider 28, and a manual clamp to manually fine-tune the slide block 22, the cost of setting up a module to drive the slide block 22 can be saved. This makes the entire welding mechanism 2 easy to adapt to the length of the roller pressing line 3, thereby moving the laser welding gun 26 to different positions on the roller pressing line 3. By setting up the roller pressing line 3, the welded product can be roller pressed, ensuring that the product is welded in a predetermined shape, while reducing the probability of post-weld deformation.

[0023] Specifically: such as Figure 2 As shown, the multi-axis module 25 includes a first linear module 251 disposed on the slide 22 along the Y-axis direction, a second linear module 252 disposed at the output end of the first linear module 251 along the X-axis direction, a third linear module disposed at the output end of the second linear module 252 along the Z-axis direction, an R-axis module 254 disposed at the output end of the third linear module 253, and a second mounting bracket 255 disposed on the R-axis module 254. The R-axis module 254 rotates around the X-axis, and the laser welding gun 26 is disposed on the second mounting bracket 255.

[0024] In actual use, the first linear module 251 drives the second linear module 252 to move along the Y-axis, the second linear module 252 drives the third linear module 253 to move along the X-axis, the third linear module 253 drives the R-axis to rise and fall, and the R-axis drives the second mounting bracket 255 and the laser welding gun 26 to rotate.

[0025] In the above design, the structure of the multi-axis module 25 enables the laser welding gun 26 to move at different angles and orientations, allowing the laser welding gun 26 to weld at different positions of the product.

[0026] Specifically: the first linear module 251 drives the second linear module 252 to move along the X-axis, the second linear module 252 drives the third linear module 253 to move along the Y-axis, the third linear module 253 drives the R-axis module 254 to rise and fall, and the R-axis module 254 drives the second mounting bracket 255 to rotate.

[0027] Specifically: such as Figure 1 and Figure 3 As shown, the roller pressing line 3 includes several roller pressing mechanisms arranged on the frame 1 along the X-axis direction. The roller pressing mechanism includes two side supports 31 symmetrically arranged in the Y-axis direction, a first shaft 32 and a second shaft 33 respectively rotatably connected to the two side supports 31 at both ends, a first wheel 34 coaxially fixed on the first shaft 32, and a second wheel 35 coaxially fixed on the second shaft 33. The first shaft 32 is located above the second shaft 33, and the first wheel 34 is located above the second wheel 35.

[0028] In actual use, when the sheet moves in the roller pressing line 3, the upper end of the sheet is squeezed by the first roller 34, and the lower end of the sheet is squeezed by the second roller 35.

[0029] In the above design, the structural design and specific implementation of the roll forming line 3 enable roll forming of the sheet metal, ensuring stable movement of the sheet metal. Furthermore, the first roller 34 and the second roller 35 can be configured into the desired shapes to roll-form the heat-affected zone of the sheet metal, preventing deformation of the heat-affected zone after welding. Alternatively, the sheet metal can be rolled into a predetermined shape by the first roller 34 and the second roller 35 before welding.

[0030] Specifically: such as Figure 3 As shown, the side support 31 includes a stand 311 mounted on the frame 1, a second plate 312 fixedly mounted on the stand 311, a first sliding plate 313 slidably and vertically connected to the stand 311, a guide post 314 slidably connected to the first sliding plate 313 and the stand 311 and whose lower end is fixedly connected to the second plate 312, a first ball bearing 315 mounted on the first sliding plate 313, a second ball bearing 316 mounted on the second plate 312, and a threaded connection to the stand 311. The system includes a threaded rod 317, a chuck 318 fixedly mounted at the lower end of the threaded rod 317, and a nut 319 located above the upper surface of the stand 311 and threadedly connected to the threaded rod 317. The upper end of the first sliding plate 313 has a groove 301 that is floatingly connected to the chuck 318. The end of the first shaft 32 is connected to the inner ring of the first ball bearing 315 and axially limited by a retaining spring. The end of the second shaft 33 is connected to the inner ring of the second ball bearing 316 and is also axially limited by a retaining spring. The floating connection between the groove 301 and the limiting plate means that the limiting plate can rotate within the groove 301, while the thickness of the limiting plate is less than the height of the groove 301. When adjusting the height of the first sliding plate 313, ensure that the lower end face of the groove 301 abuts against the lower end face of the limiting plate when the plate passes under the first wheel 34.

[0031] In actual use, the rotation of shaft 32 drives the inner ring of the ball bearing to rotate, and the rotation of shaft 33 drives the inner ring of ball bearing 316 to rotate. When it is necessary to adjust the height of slide plate 313 to change the height difference between wheel 34 and wheel 35, loosen nut 319, rotate threaded rod 317, so that threaded rod 317 drives the limiting plate to rotate synchronously and then displaces along the screw axis. After the limiting plate rotates in the slot 301, it drives slide plate 313 to rise and fall to the predetermined position through the slot 301. Then tighten nut 319.

[0032] In the above design, the structural design and specific implementation of the side support 31 facilitate the adjustment of the distance between the first slide plate 313 and the second slide plate 312, thereby changing the distance between the first wheel 34 and the second wheel 35 to adapt to plates of different thicknesses.

[0033] Specifically: such as Figure 3As shown, the roller pressing mechanism also includes a connecting strip 36, the two ends of which are fixedly connected to the two side supports 31 respectively.

[0034] In the above design, the connection stability of the two side supports 31 can be ensured by setting the connecting strip 36.

[0035] Specifically: such as Figure 2 and Figure 4 As shown, the welding mechanism 2 also includes a protective gas assembly, which includes a hose 27 and a gas tank. The hose 27 has an inlet and an outlet at its two ends, respectively. The hose 27 is connected to the gas tank at one end of the inlet, and the hose 27 is mounted on the multi-axis module 25 at the other end of the inlet.

[0036] During actual welding, the protective gas in the gas tank is blown around the weld pool through a hose to prevent air from entering the weld and reduce the probability of post-weld cracks.

[0037] In the above design, the welding quality of the weld can be improved and the probability of post-weld cracks can be reduced by setting a protective gas component.

[0038] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
