Description

Technical Field

[0001] The present application relates to the field of laser welding, and in particular to a laser welding device with built-in protective facilities. Background Art

[0002] Laser is considered to be an ideal heat source for welding. Laser welding is one of the most important applications of laser technology. It uses polarizers to reflect the laser beam to concentrate it in a focusing device to generate a huge energy beam. It is a processing technology that uses the characteristics of the interaction between laser beam and matter to weld materials (including metals and non-metals). Laser welding has the advantages of concentrated heating, less heat input, small deformation, fast welding speed (up to several meters to more than ten meters per minute), large welding depth-to-width ratio and high quality. It is not only suitable for conventional materials, but also for refractory metals, heat alloys, titanium alloys with different thermal physical properties, workpieces with large differences in volume and thickness, and components near the weld that are flammable, cracked and exploded when heated. The weld is beautiful and beautiful. In many cases, the weld can be as strong as the parent material. Moreover, the laser beam can be transmitted through optical fiber, so the complex beam transmission system can be omitted, which is suitable for flexible manufacturing systems or remote processing. Laser welding can be either spot welding or continuous seam welding.

The electric slide rail 6 and the electric slider 5 structure can adjust the position of the laser welding machine body 7 to achieve precise positioning and operation. The telescopic rod 21 hinged on the side of the laser welding machine body 7 is connected to the vertical plate 22 fixed on the top of the machine tool 1, so that the baffle 23 can be raised and lowered according to the stroke of the electric slider 5 to adapt to different welding scenes, so that the welding process can be finely adjusted and controlled. Protective facilities such as baffles 23 and slag cleaning devices 3 can effectively prevent sparks, smoke and spattered welding slag from affecting the equipment during welding, thereby improving welding efficiency and safety. The bottom of the inner wall of the fixed block 24 is rotatably connected to a rotating rod 26 through a bearing. The rotating rod 26 movably penetrates the fixed block 24 and extends to the top. The outer wall of the rotating rod 26 is fixedly sleeved with a first circular gear 27. The side of the electric slider 5 is equipped with a first rack 29. The top of the rotating rod 26 is fixedly connected to a grinding disc 28. The bottom of the fixed block 24 is connected to the rotating rod 26 through a bearing. The rotating rod 26 can rotate in the fixed block 24, and the outer wall is installed with a first circular gear 27. The electric slider 5 meshes with the first circular gear 27 on the rotating rod 26 through the first rack 29 to drive the rotating rod 26 to rotate. The top of the rotating rod 26 is connected to a grinding disc 28. When the position of the laser welding machine body 7 is adjusted after welding, the grinding disc 28 can clean the bottom of the laser welding machine body 7, improve the welding quality and clean the residues in the welding process.

[0025] When the above equipment is used, the workpiece is placed on the top of the welding bracket, and then the welding bracket is placed on the top of the machine tool 1, the laser welding machine body 7 is started, the workpiece is welded, and the electric slide 5 is started to slide on the inner wall of the electric slide rail 6. The electric slide 5 drives the laser welding machine body 7 to move forward. During the movement of the laser welding machine body 7, the telescopic rod 21 is driven to rotate counterclockwise with the hinge point of the vertical plate 22 as the center of the circle, driving the cross bar 25 to rise, and the cross bar 25 drives the fixed block 24 and the baffle 23 to rise. At the same time, the baffle 23 slides on the inner wall of the inclined groove through the sliding rod 210, so that the baffle As the plate 23 rises, it moves toward the electric slider 5. As the laser welding machine body 7 approaches the front, the baffle 23 also rises toward the electric slider 5 to block the flying slag during welding of the laser welding machine body 7. When the electric slider 5 slides to the end of the electric slide rail 6, the electric slider 5 drives the first rack 29 to move toward the front, and the baffle 23 also rises to the highest point. The first rack 29 drives the first circular gear 27 to rotate, and the first circular gear 27 drives the rotating rod 26 to rotate. The rotating rod 26 drives the grinding disc 28 to rotate, and the grinding disc 28 grinds and cleans the welding slag at the bottom of the laser welding machine body 7.
