Description

Technical Field

[0001] This utility model relates to the field of laser welding machines, and in particular to a laser welding machine that prevents material displacement during welding. Background Technology

[0002] Laser welding machines are used in fields where there are basic requirements for welding position accuracy, such as precision parts, electronic components, and small structural parts. They are especially suitable for small-scale, high-frequency precision welding operations, and can meet the basic requirements for the stability of the welding position of materials in such scenarios, providing basic equipment support for subsequent precise welding operations.

[0003] Existing laser welding machines that prevent material displacement during welding can be put into use without complicated pre-debugging procedures. Operators only need to set basic parameters such as laser power and welding speed according to the material and thickness of the workpiece, fix the workpiece on the machine's worktable, and start the machine. The machine will then automatically control material displacement during the welding process.

[0004] Existing laser welding machines designed to prevent material welding displacement have significant drawbacks. They struggle to meet diverse welding needs, lack multi-angle adjustment, and the welding torch typically only allows linear movement, lacking a flexible angle adjustment mechanism. When welding complex welds or inclined surfaces, the workpiece must be moved for adaptation, increasing positioning difficulty, raising the risk of welding displacement, and compromising welding accuracy. Furthermore, the welding torch is relatively fixed, often using integrated fixing or cumbersome bolt connections. Changing to different torch models or performing maintenance requires disassembling multiple components, resulting in time-consuming operations, increased equipment downtime, and disruption of welding continuity. Therefore, this paper proposes a laser welding machine designed to prevent material welding displacement to address these issues. Utility Model Content

[0022] 1.

This ensures the accuracy of the welding position, protects the appearance of the material, and further improves the quality of the welded product. Attached Figure Description

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.

[0032] Reference Figures 3-5 This utility model provides an embodiment of a laser welding machine for preventing material displacement during welding. The machine includes a base plate 1, which provides stable support for the entire machine. A column 15 is fixedly connected to the top outer wall of the base plate 1. The column 15 is used to install a lifting slide rail 16 and provides a lifting guide foundation. The lifting slide rail 16 is fixedly connected to the outer wall of the column 15. A second motor 3 is also fixedly connected to the top outer wall of the base plate 1. The second motor 3 serves as a lifting power source, and its output end is connected to a transmission belt 17 via a transmission wheel, which can drive the transmission belt 17 to rotate. A lifting slider 18 is slidably connected to the outer wall of the lifting slide rail 16. The outer wall of the transmission belt 17 is fixedly connected to the lifting slide rail 16. On the outer wall of the slider 18, when the transmission belt 17 is running, it can drive the lifting slider 18 to slide up and down along the lifting slide rail 16, thereby realizing the height adjustment of the welding gun 23. The outer wall of the lifting slider 18 is fixedly connected to the translation slide rail 19, which can drive the translation slide rail 19 to rise and fall synchronously. The outer wall of the translation slide rail 19 is slidably connected to the translation slider 20. The end of the translation slide rail 19 is fixedly connected to the third motor 4. The third motor 4 serves as the translational power source, and its output end is connected to the transmission belt 17 through the transmission wheel, which can drive the transmission belt 17 to move. The outer wall of the transmission belt 17 is fixedly connected to the locking block 21, and the outer wall of the translation slider 20 is fixedly connected to the outer wall of the locking block 21.

[0033] Reference Figures 3-5When the transmission belt 17 moves, it can drive the locking block 21 and the translation slider 20 to slide horizontally along the translation rail 19, thereby adjusting the horizontal position of the welding torch 23. The outer wall of the locking block 21 is fixedly connected to the fourth motor 5, which can drive the fourth motor 5 to move synchronously. The fourth motor 5 can drive the mounting base 22 to rotate to adjust the angle of the welding torch 23. The output end of the mounting base 22 is fixedly connected to the mounting base 22. The welding torch 23 is provided on the outer wall of the mounting base 22. The outer wall of the mounting base 22 has a mounting groove that is compatible with the welding torch 23. The outer wall of the welding torch 23 fits tightly with the inner wall of the mounting groove, and the depth of the mounting groove matches the radius of the outer wall of the welding torch 23. The mounting groove can perform preliminary positioning of the welding torch 23. The outer wall of the mounting base 22 is fixedly connected to the buckle 24 by bolts. The buckle 24 can be firmly fixed by bolts, and at the same time, it is convenient to quickly disassemble and replace the welding torch 23, reducing downtime.

[0034] Reference Figures 1-3 A mounting bracket 7 is fixedly connected to the top outer wall of the base plate 1. The mounting bracket 7 is used to install the first motor 2, the threaded rod 6, and the reciprocating slide rail 8, providing a mounting base for the workpiece positioning structure. The first motor 2 is fixedly connected to the end of the mounting bracket 7. The first motor 2 serves as a reciprocating power source, and its output end is fixedly connected to the threaded rod 6, which can drive the threaded rod 6 to rotate. The threaded rod 6 is rotatably connected to the inner wall of the mounting bracket 7. The mounting bracket 7 can support and limit the threaded rod 6, ensuring its stable rotation. The reciprocating slide rail 8 is fixedly connected to the top outer wall of the mounting bracket 7. A reciprocating slider 9 is slidably connected to the outer wall of the reciprocating slide rail 8. The reciprocating slide rail 8 provides a sliding guide for the reciprocating slider 9 to ensure its stable movement direction. A threaded block 10 is fixedly connected to the outer wall of the reciprocating slider 9. The outer wall of the threaded rod 6 is threadedly connected to the threaded block 10. When the threaded rod 6 rotates, it drives the threaded block 10 and the reciprocating slider 9 to slide along the reciprocating slide rail 8 through thread transmission, so as to realize the position adjustment of the support plate 11 to adapt to workpieces of different lengths. The top outer wall of the threaded block 10 is fixedly connected to the support plate 11, which provides a platform for placing the workpiece.

[0035] Reference Figures 1-3 An electric push rod 12 is fixedly connected to the bottom outer wall of the support plate 11, and a push plate 13 is fixedly connected to the telescopic end of the electric push rod 12. The electric push rod 12 can drive the push plate 13 to extend and retract up and down. When the push plate 13 rises, it can cooperate with the support plate 11 to clamp the workpiece and avoid welding displacement. A baffle 14 is fixedly connected to the top outer wall of the support plate 11, and a buffer pad is fixedly connected to the inner wall of the baffle 14. The outer wall of the buffer pad is completely in contact with the inner wall of the baffle 14, and the height of the buffer pad is consistent with the height of the baffle 14. The baffle 14 can laterally limit the workpiece to achieve precise positioning, while the buffer pad can prevent the workpiece surface from being crushed during clamping and protect the appearance of the workpiece.

[0036] Working principle: The mounting frame 7 provides the mounting base for the workpiece positioning structure. When the first motor 2 is started, its output end drives the threaded rod 6 to rotate stably on the inner wall of the mounting frame 7. Because the threaded rod 6 is threadedly connected to the threaded block 10, and the threaded block 10 is fixed to the reciprocating slider 9, which slides along the reciprocating slide rail 8, the rotation of the threaded rod 6 will drive the threaded block 10, the reciprocating slider 9, and the top support plate 11 to move along the reciprocating slide rail 8 until the support plate 11 is adjusted to a position suitable for the workpiece length. After placing the workpiece on the support plate 11, the motor is started... The push rod 12, with its telescopic end pushing the push plate 13 upward, cooperates with the support plate 11 to clamp the workpiece. At the same time, the baffle 14 on the top of the support plate 11 provides lateral restraint to the workpiece, preventing lateral displacement. The buffer pad on the inner wall of the baffle 14 can protect the workpiece surface from being crushed during clamping, ultimately achieving stable positioning of the workpiece and preventing welding displacement from the source. Then, the welding torch 23 is first placed into the mounting groove of the mounting base 22. After the mounting groove initially positions the welding torch 23, the bolts are tightened to secure the buckle 24, firmly fixing the welding torch 23 to the mounting base. On 22, if the welding torch 23 needs to be replaced, it can be quickly disassembled by loosening the bolts. Start the second motor 3, which drives the transmission belt 17 through the transmission wheel. Since the transmission belt 17 is fixed to the lifting slider 18 and the lifting slider 18 slides along the lifting slide rail 16 on the column 15, the transmission belt 17 will drive the lifting slider 18 and the bottom translation slide rail 19 to move up and down, thereby adjusting the height of the welding torch 23. Start the third motor 4, which drives another set of transmission belts 17 through the transmission wheel. Since the transmission belt 17 is engaged with the locking block 21 and the locking block 21 is engaged with the translation slide rail 19, the welding torch 23 can be adjusted up and down. The slider 20 is fixed and slides along the translation rail 19. The transmission belt 17 drives the locking block 21, the fourth motor 5 and the mounting base 22 to move horizontally, thereby adjusting the horizontal position of the welding torch 23. The fourth motor 5 is started, and its output end drives the mounting base 22 to rotate, which in turn drives the welding torch 23 to adjust its angle to adapt to the welding requirements of different inclined surfaces or irregular weld seams of the workpiece. After the position and angle of the welding torch 23 are adjusted to the correct position, the welding torch 23 can be started to perform welding operations. There is no need to move the positioned workpiece throughout the process, which further ensures the welding accuracy.
