Carbon dioxide arc welding device provided with safety goggles

[0014] Examples. A carbon dioxide gas shielded welding device with protective glasses, composed as Figure 1-3 As shown, the track 1 is included. The track 1 is provided with a trolley 2 and the trolley 2 is connected with a transparent box body 20; the trolley 2 is also provided with a fixed block 3, the fixed block 3 is provided with a gear 5, and the gear 5 is connected with a motor 6; The rack 4 meshed with the gear 5 is connected with a lateral limit block 7, which is connected with the gun head 8 by bolts, and the gun head 8 is connected with a welding machine 17, and both ends of the gun head 8 are equipped with fine adjustment mechanisms 9. The fine adjustment mechanism 9 is arranged on the moving plate 10, the moving plate 10 is connected to the protective glasses 18 through the support rod 19; the moving plate 10 is also connected with a cylinder 11; the fine adjustment mechanism 9 includes a rotating button 13, which is connected with The worm 12 is connected with a push rod 14, and the push rod 14 is connected with a pressure block 15. The horizontal limit block 7 fixes the gun head 8; the two fine-adjusting mechanisms 9 are arranged on both sides of the gun head 8, which can be used to support the gun head and can also fine-tune the gun head 8 longitudinally . The trolley 2 is provided with wheels 16 to facilitate movement. There are four support rods 19, which respectively support the four corners of the protective glasses 18, which are relatively stable; the air cylinder 11, the moving plate 10, the fine adjustment mechanism 9 and the gun head 8 are all arranged in the transparent box 20; The rod 19 is connected with the protective glasses 18 by screws, which is convenient for disassembly; the protective glasses 18 can be provided with a transparent window or be fully transparent, and the welding situation can be observed in real time.

[0015] Working principle: such as Figure 1-3 As shown, after the installation of the device of the present invention is completed, when welding is required, first place the steel structure equipment to be welded, and then use the cylinder 11 to push for lateral adjustment to the corresponding position, start the motor 6, and the motor 6 drives the gear 5 to rotate. The gear 5 makes the rack 4 move longitudinally until it moves to the welding seam, and starts the welding machine 17 and the trolley 2. The trolley 2 drives the box 20 to move. During the welding process, the running speed and welding of the trolley 2 can be adjusted according to the actual situation. The position of welding can be adjusted by the fine adjustment mechanism 9, which improves the welding quality.
