Description

Technical Field

[0001] This utility model relates to the field of laser welding, and in particular to a precision positioning dual-beam laser welding auxiliary platform. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. In the industrial manufacturing field, laser welding technology is widely used for welding metal materials due to its high efficiency, precision and small heat-affected zone.

[0003] During the welding process, the workpiece is prone to slight displacement due to the thermal effect or mechanical vibration of the laser beam, which leads to a decrease in welding accuracy and even welding defects. At the same time, metal vapor will be formed in the welding area. After cooling, this vapor will condense into tiny particles, namely spatter or debris. If not cleaned in time, it may accumulate on the surface of the workpiece or inside the equipment, which not only affects the subsequent welding quality but also poses a safety hazard. Utility Model Content

[0004] To overcome the drawbacks of workpiece displacement and debris generation during the welding process, this utility model provides a precision positioning dual-beam laser welding auxiliary platform.

[0005] The technical implementation scheme of this utility model is as follows: A precision positioning dual-beam laser welding auxiliary platform includes a frame, a placement platform, a drive assembly, a welding head, a first electric slide rail, a partition plate, a fixed seat, a first sliding rod, a first elastic element, a limiting plate, a pressing mechanism, and a cleaning assembly. The upper side of the frame is provided with a placement platform and a drive assembly. Two welding heads are mounted on the drive assembly. The front and rear sides of the placement platform are provided with first electric slide rails.

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0020] A precise positioning dual-beam laser welding auxiliary platform, such as Figures 1-5 As shown, the assembly includes a frame 1, a placement platform 2, a drive assembly 3, a welding head 4, a first electric slide rail 5, a partition plate 6, a fixed seat 7, a first sliding rod 8, a first elastic element 9, a limiting plate 10, a pressing mechanism, and a cleaning assembly. The frame 1 has a placement platform 2 and a drive assembly 3 on its upper side. The drive assembly 3 is equipped with two welding heads 4 and is an XYZ three-axis drive. The placement platform 2 has first electric slide rails 5 on both the front and rear sides. The sliders of the two first electric slide rails 5 are respectively connected to the front and rear ends of the partition plate 6. The partition plate 6 is located in the middle of the placement platform 2. The frame 1 has two fixed seats 7 on both the left and right sides. The fixed seats 7 have first sliding rods 8 that slide on them. The first sliding rods 8 on the left and right sides of the frame 1 are respectively connected to the two limiting plates 10. The first elastic element 9 is wrapped around the outside of the first sliding rod 8. The first elastic element 9 connects the fixed seat 7 and the limiting plate 10. The welding head 4 has a pressing mechanism that always presses the welded part during welding. The frame 1 has cleaning assemblies for cleaning debris on both the left and right sides.

[0021] During use, two welding parts are placed on the placement platform 2 and separated by the partition plate 6. The height of the partition plate 6 can be adjusted by the first electric slide rail 5 to accommodate welding parts of different sizes. The welding parts contact the limiting plate 10 and squeeze the limiting plate 10 to move outward. At this time, the first elastic element 9 contracts and always provides clamping force to ensure that the welding parts do not shift in the horizontal direction. Then, the drive assembly 3 is started, and the drive assembly 3 drives the welding head 4 to weld the welding parts. At the same time, the pressing mechanism on the welding head 4 always presses the welding parts to ensure the stability of the welding and improve the welding quality. After the welding is completed, the cleaning assembly cleans the upper side of the frame 1 to keep the working environment clean and avoid debris from affecting the welding quality.

[0022] like Figure 4 As shown, the pressing mechanism includes a second sliding rod 11, a second elastic element 12, and a pulley 13. The welding head 4 is slidably provided with the second sliding rod 11, which is connected to the pulley 13. The second elastic element 12 is wrapped around the outside of the second sliding rod 11. The second elastic element 12 is connected to the welding head 4 and the pulley 13. When the welding head 4 is performing welding work, the pulley 13 contacts the workpiece and applies a constant pressure by compressing the second elastic element 12 to ensure that the welded part does not move vertically during the welding process.

[0023] like Figure 5 As shown, the cleaning assembly includes a second electric slide rail 14, a third electric slide rail 15, a fixed frame 16, a movable frame 17, and a brush 19. The second electric slide rail 14 is provided at both the left and right ends of the upper side of the frame 1. The slider of the second electric slide rail 14 is connected to the third electric slide rail 15. The slider of the third electric slide rail 15 is connected to the fixed frame 16. The movable frame 17 is slidably provided at the end of the fixed frame 16 away from the third electric slide rail 15. The brush 19 is provided on the lower side of the fixed frame 16 and the movable frame 17. By linking the second electric slide rail 14 and the third electric slide rail 15, the fixed frame 16 and the movable frame 17 are moved so that the brush 19 covers the welding area and cleans the debris generated during the welding process.

[0024] like Figure 5 As shown, the cleaning assembly also includes a sliding part 171 and a bolt 18. The sliding part 171 is provided on the movable frame 17 and is slidably connected to the fixed frame 16. The sliding part 171 has multiple mounting holes 172. The bolt 18 is threadedly connected to the fixed frame 16. The sliding part 171 can be fixed to the fixed frame 16 by the bolt 18 and the mounting holes 172. The position of the movable frame 17 relative to the fixed frame 16 can be adjusted by the bolt 18 and the mounting holes 172, thereby adjusting the length of the brush 19 to fill the cleaning blind spots.

[0025] The fixed frame 16 has two rows of brushes 19 on its lower side, the movable frame 17 has three rows of brushes 19 on its lower side, and the sliding part 171 has one row of brushes 19 on its lower side. The brushes 19 on the lower side of the sliding part 171 are located between the two rows of brushes 19 on the lower side of the fixed frame 16, making full use of the space and ensuring that the fixed frame 16, the movable frame 17 and the brushes 19 on the lower side of the sliding part 171 do not collide or interfere when the sliding part 171 is moved.

[0026] The partition plate 6 is a T-shaped plate. During the welding process, the T-shaped plate can prevent the welded parts from moving vertically on the side close to the partition plate 6.

[0027] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
