Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, in particular to a welding device with precise positioning. Background Art

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. Welding has the advantages of easy forming, low production cost and strong adaptability, and is widely used in various fields of industrial manufacturing. The welding devices currently used have poor positioning effects, which makes it easy to make mistakes during the welding process, which not only reduces the efficiency of the welding machine, but also brings trouble to the staff, and needs to be improved;

[0003] After searching, the China Patent Network disclosed a laser welding device with precise positioning effect, and its authorization announcement number is CN216028769U. The patent can adjust the angle through the setting of the cylinder and the movable block, avoiding the welding error caused by the wrong angle. The setting of the handle, the limit clamp rod, the screw rod, the nut and the support rod can play a clamping role, avoiding the material shaking during the welding process. The setting of the hand crank, the rotating rod, the first gear, the second gear, the threaded rod, the threaded sleeve and the fixed plate can adjust the distance, avoiding the poor welding effect caused by insufficient distance, and at the same time solves the problem of poor positioning effect of the existing laser welding device.

[0004] However, this patent is not convenient for absorbing the smoke generated during the welding process. Since the smoke generated during welding contains iron oxide, silicon oxide, manganese oxide, fluoride, etc., these substances can irritate and inflame the respiratory system. Long-term exposure may lead to chronic respiratory diseases. Therefore, the drifting smoke will not only pollute the environment of the production workshop, but also cause harm to the health of the workers over a long period of time. There are certain safety hazards in its use. Therefore, a welding device with precise positioning is now proposed. Utility Model Content
