[0002] Laser welding machine, also commonly known as laser welding machine, laser welding machine, is a machine used for laser welding of material processing. Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation diffuses to the inside of the material through heat conduction, and the material is melted to form a specific molten pool to achieve the purpose of welding. Therefore, the laser welding machine needs to fix the position of the processed workpiece during the processing. Laser welding machines are needed in the production process of lighters, gas bottles, and lighter molds.

The laser welding machine body includes a laser welding module and a processing table. The bottom of the processing table is fixedly connected with a fixed plate, and the surface of the fixed plate is provided with a transmission component. The surface wall of the transmission component is fixedly connected with a clamping mechanism. By setting a through groove in the clamping mechanism, a movable space can be provided for the mobile frame, and then the mobile frame is driven to move by the transmission component. Through the cooperation of the clamping seat and the clamped workpiece, the welded workpiece can be clamped and fixed, and the clamping effect of the laser welding machine body is enhanced, thereby improving the processing accuracy of the laser welding machine body. By setting the cooperation of the fixed seat, the first limit groove and the second limit groove in the clamped workpiece, the laser welding machine body can meet the clamping work of different models of workpieces, and the clamping effect of the laser welding machine body is improved. However, the device has a weld with an angle design for the clamping angle and the welding angle, and the welding effect is difficult to guarantee, and it is inconvenient to use, and the practicality needs to be enhanced.

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1 — Figure 5As shown, a mold laser welding machine includes a base 101, a placing table 103 is connected to the base 101 by bolts, two symmetrically arranged clamping mechanisms 2 are fixedly installed on the top of the base 101, a welding mechanism is arranged above the placing table 103, a suction mechanism is installed on the welding mechanism, the welding mechanism includes a guide frame 301, symmetrically arranged clamping components are installed on both sides of the guide frame 301, a laser welder 306 is slidably connected in the guide frame 301, and a wire interface 307 is connected to the top of the laser welder 306 by bolts. The wires need to be connected to the wire interface 307. The top of the base 101 is connected to the bracket 102 by bolts. The bracket 102 is connected to a driving mechanism for driving the laser welder 306 to move by bolts. When in use, the clamping assembly is fixedly set on the front and rear sides of the workpiece, the guide frame 301 is set parallel to the welding gap, the weld is close to the bottom of the welding head of the laser welder 306, and the laser welder 306 moves straight in the guide frame 301, which ensures a good welding effect and prevents welding sparks from splashing out of the guide frame 301, thereby improving the welding effect.

[0025] In this embodiment, the clamping assembly includes a screw rod 302, which is rotatably connected to both ends of the guide frame 301. A connecting block 303 is threadedly connected to the screw rod 302. A rotating shaft 304 is bolted to the bottom of the connecting block 303. A clamping block 305 for clamping the workpiece is rotatably connected to the bottom of the rotating shaft 304. When the screw rod 302 rotates, the screw rod 302 is connected to the rotating shaft 304 through the connecting block 303 to fix the clamping block 305 on both sides of the workpiece, so that the guide frame 301 can be stably installed on the workpiece to prevent deviation during welding.

[0026] In this embodiment, the driving mechanism includes a cylinder 401, which is connected to the top of the bracket 102 by bolts, and the output end of the cylinder 401 is connected to a moving frame 402 for driving the laser welder 306 to move forward and backward by bolts.

[0027] In this embodiment, a guide rod 308 for driving the laser welder 306 to move is connected to the top of the laser welder 306 by bolts, a sliding sleeve 403 is provided inside the movable frame 402, and the guide rod 308 is slidably connected inside the sliding sleeve 403. The guide rod 308 can slide up and down inside the sliding sleeve 403 to adapt to welding of workpieces of different heights, thereby improving the scope of application.

[0028] In this embodiment, the clamping mechanism 2 is a hydraulic cylinder and is connected to the same oil cylinder. The clamping mechanism 2 is located on both sides of the placement table 103. The clamping mechanism 2 clamps and fixes the left and right sides of the workpiece to prevent the workpiece from shifting during welding.

[0029] In this embodiment, the air suction mechanism includes an exhaust fan 501, which is connected to one side of the base 101 by bolts. An exhaust pipe 502 is plugged into the exhaust fan 501, and a plurality of connecting hoses 503 are glued to the side of the exhaust pipe 502. The exhaust end of the connecting hose 503 extends into the guide frame 301.

Then, the guide frame 301 is pulled down, and the guide rod 308 slides in the sliding sleeve 403. The screw rod 302 is rotated to make the clamping block 305 at the front and back sides of the workpiece. Then, the angle of the guide frame 301 is adjusted so that the direction of the guide frame 301 is parallel to the welding gap, and the welding seam is close to the bottom of the welding head of the laser welder 306. Then, the screw rod 302 is rotated in the opposite direction to make the clamping block 305 stable. The workpiece is fixedly clamped on the front and back sides, and finally the wires are connected to the wire interface 307. When welding begins, the cylinder 401 is used to push and pull the movable frame 402. The movable frame 402 drives the guide rod 308 to move through the sliding sleeve 403. The guide rod 308 leads the laser welder 306 to move straight in the guide frame 301 to weld the workpiece weld. At the same time, the exhaust fan 501 is turned on. The toxic gas generated by laser welding will be directly sucked away by the connecting hose 503 arranged on the side to avoid being dispersed into the air and inhaled by the workshop workers.
