Description

Technical Field

[0001] The present invention relates to the technical field of laser welding, and in particular to a laser welding platform for sheet metal processing. Background Technique

[0002] Laser welding is an efficient and precise welding method that uses a laser beam with a high energy density as a heat source. It is an important aspect of the application of laser material processing technology. Generally, a continuous laser beam is used to complete the connection of materials. A sheet metal sewage filtration grille refers to a grille device that is manufactured by sheet metal processing technology and is used to filter impurities in sewage treatment. Its core is to form a filtering unit with specific pore diameters and structures through cold processing techniques such as cutting, punching, bending, and welding of metal thin plates (such as stainless steel plates, galvanized steel plates, etc.), which is used to intercept suspended solids, solid particles, and other impurities in sewage to ensure the normal operation of subsequent water treatment processes.

[0003] In the prior art, for the metal fences or filtration grilles formed by sheet metal parts, laser welding of fences or grilles is required during the production process. However, in actual use, it generally needs to be completed through multiple processes, and the operation is very cumbersome. Moreover, due to the size requirements of different fences or grilles, the spacing of the grille bars in the middle of the grille, that is, the spacing of the thin sheet metal parts, is different. Therefore, during the welding process, it is also necessary to accurately clamp and fix them with fixtures. This process often requires manual operation, and manual operation has the problem of insufficient accuracy, which will seriously affect the product quality.

[0026] Specifically, a first extension plate 20 is fixedly connected to the upper end surface of the measuring disk 15. The first extension plate 20 is designed with a hollow internal structure and an open structure at both ends. Both ends of the first extension plate 20 are movably connected to a second extension plate 21. One end of the second extension plate 21 extends into the first extension plate 20 through the opening of the first extension plate 20. A screw 22 is threadedly connected to the side surface of the first extension plate 20.

Limit blocks 23 are fixed at both ends of the second extension plate 21.

[0027] Working principle: During operation, the user places the grid cross bar 11 in the U-shaped engaging member 30 of several clamping members 5. Then, the user rotates the drive disk 29 counterclockwise through the handle rod, thereby driving the U-shaped engaging member 30 fixed to the drive disk 29 to clamp the cross bar through the U-shaped engaging member 30. And if the cross bar is a cylindrical structure, the cylindrical rod can be clamped and fixed through the engaging groove 31 on the U-shaped engaging member 30. During the rotation of the drive disk 29, the shaft rod fixed to the drive disk 29 will be synchronously driven to rotate. At this time, the rubber block fixed to the other end of the shaft rod and in interference contact with the inner wall of the square tube 28 inside the square tube 28 will be displaced. Since the rubber block is in interference contact with the square tube 28, when the user finishes rotating, the drive disk 29 and the U-shaped engaging member 30 can be limited and fixed through the frictional resistance of the interference contact. At this time, the fixing of the grid cross bar 11 is completed through the clamping member 5. The user can also adjust the positions of several support rods 4 according to the length of the grid cross bar 11. The support rods 4 are slidably connected to the first cross bar 1 through the bottom slide rail and are locked and fixed through the self-locking engaging member. The first cross bar 1 and the second cross bar 2 can also be slidably adjusted in the same way. After fixing the two grid cross bars 11 in the above manner, at this time, it is necessary to fill the grid vertical bars 12 between the two grid cross bars 11. According to the grid production requirements, the grid vertical plate and the grid cross bar 11 are not vertically distributed. The user needs to adjust and calibrate the connection angle between the grid vertical bar 12 and the grid horizontal plate through the calibrator according to the welding angle requirements before welding can be carried out. At this time, the user needs to adjust the lengths of the first extension plate 20 and the second extension plate 21 according to the length of the grille vertical rod 12, and lock and fix the second extension plate 21 with bolts, so that the lengths of the adjusted first extension plate 20 and the second extension plate 21 match the grille vertical rod 12 to be welded. Then the user places the grille vertical rod 12 on the first extension plate 20 and the second extension plate 21, and the two ends of the grille vertical rod 12 are limited and fixed by the limit blocks 23. Finally, the user rotates the measuring disc 15. During the rotation of the measuring disc 15, the scale corresponds to the pointer 14 on the fixed plate 13, and the through pointer 14 coincides with the corresponding scale line to calculate the rotation angle of the measuring disc 15, so as to determine the angle between the grille vertical rod 12 and the grille cross plate. Subsequently, the user rotates the first bolt 19 to drive the clamping plate 18 to squeeze and clamp the measuring disc 15 for fixation, so as to limit the angle of the measuring disc 15. And the measuring disc 15 is slidably connected to the main connecting rod 3 through the bottom fixing seat 16. Therefore, the laser welding work can be carried out by adjusting the grille vertical rod 12 one by one through the sliding calibrator. Subsequently, the user connects the rotating shaft 8 to an external motor, and adjusts the angle of the welded grille on the main connecting rod 3 and the main connecting rod 3 by left and right flipping to meet the needs of the laser welding angle.
