Description

Technical Field

[0001] The utility model belongs to the technical field of welding devices and relates to a laser composite welding device. Background Art

[0002] Among existing welding processes, laser welding is widely used in industrial manufacturing due to its high efficiency and high precision, and is particularly suitable for welding precision machining and high-strength materials. However, the laser welding equipment currently on the market typically relies on a fixed welding head when handling different types of welds (such as flat welds and fillet welds). This results in a lack of flexibility in the welding process, making it complex and inefficient, especially when welding welds of varying shapes.

[0003] Existing laser welding equipment generally has the following characteristics:

[0004] Fixed-angle welding heads: Traditional laser welding equipment is often equipped with fixed-angle welding heads. This design can meet certain welding tasks, such as welding straight seams. However, when it comes to fillet welds, the fixed angle of the welding head makes it difficult to adapt to the twists and turns or angles of the weld, resulting in poor weld quality. Manual adjustment of the welding head angle or even replacement of the welding head is often required to accommodate different welding requirements.

[0005] Single adjustment mechanism: Existing laser welding equipment generally features only a simple single-axis adjustment mechanism, which allows the welding head to move up and down in the vertical direction (Z-axis). This adjustment method cannot meet the multi-dimensional position adjustment requirements of welding tasks, especially when welding complex workpieces. Precise horizontal (X-axis) or vertical (Y-axis) adjustments are impossible, limiting the applicability of the equipment.

[0006] Manually changing welding heads: Because existing equipment cannot simultaneously handle welds of varying angles, operators often need to manually change welding heads to accommodate the varying requirements of flat and fillet welds. This manual process is cumbersome and time-consuming, increasing operational difficulty and production costs. Even slight deviations during the replacement process can lead to reduced weld quality, uneven welds, cracks, and other issues.

[0007] Lack of automated seam tracking systems: While some existing equipment incorporates seam tracking systems, these systems are often simplistic in design and can only roughly track straight seams, failing to effectively handle sudden changes in the seam path or complex curves. This makes it difficult for the welding head to accurately follow the seam trajectory during welding, which in turn affects weld quality. In the absence of automated seam tracking, operators must manually adjust the welding head's position, which undoubtedly increases the difficulty and operational burden of welding.

[0008] Therefore, there is a need for a laser hybrid welding device that is compatible with flat welds and fillet welds, can realize different types of welding, and can track the position of the weld in real time. Utility Model Content

These adjustment devices are mainly used to achieve flexible adjustment of the welding head 205 at different positions and angles, ensuring that various welding requirements can be met in complex welding scenarios.

[0071] like Figure 4 As shown, the adjustment platforms in the welding head assembly 2 of the present invention all use the screw principle.

[0076] First rotary adjustment plate 204: The first rotary adjustment plate 204 adjusts the vertical angle between the arc welding head 205 and the laser welding head 1 by rotating the third adjustment platform 207 through the guide groove 2041 thereon; when making the adjustment, first loosen the three connecting bolts, rotate the third adjustment platform 207 along the direction of the guide groove 2041 to the right position, and then tighten the bolts. Figure 5 shown.

[0077] Arc welding head 205: The arc welding head 205 is used for filler wire welding, and specifically may include MIG, MAG, TIG, etc., and is used in conjunction with a laser welding head to improve welding efficiency.

[0078] Second rotary adjustment plate 206: The second rotary adjustment plate 206 adjusts the longitudinal angle between the arc welding head 205 and the laser welding head 1 by rotating the arc welding head 205 through the rotary adjustment slot 2061 thereon; when making the adjustment, first loosen the three connecting bolts, and then tighten the bolts after the arc welding head 205 is rotated into place along the rotary adjustment slot 2061. Figure 6 shown.

[0079] Third adjustment platform 207: The third adjustment platform 207 includes a third adjustment knob 2072, a third coupling 2073, a third guide rail 2074, and a third slider 2075. Utilizing the principle of a lead screw, rotating the lead screw by a certain angle controls the vertical movement of the nut on the lead screw, thereby driving the third slider 2075 mounted above the nut for adjustment. To make adjustments, the lock must be unlocked and the third adjustment button 2072 rotated. Precise adjustments can be made using the scale on the third adjustment knob 2072. In one embodiment, one or more adjustment platforms can be replaced with an electric adjustment platform driven by a servo motor, enabling automated adjustment and higher precision. The electric platform can be integrated into the welding control system for more efficient automatic adjustment.

[0082] The entire welding head assembly used in this utility model is based on an adjustment platform, including a rotary adjustment plate, which is connected and fixed to the back plate of the laser welding device. The positional relationship between the adjustment platform and the adjustment plate ensures that the welding head can be flexibly adjusted in multiple directions, covering all adjustment requirements in the horizontal direction (X-axis), vertical direction (Z-axis), and angular direction.
