Device for inhibiting smoke dust and splashing in laser welding

The utility model provides a device for restraining smoke dust and splashing in laser welding. The device comprises a rear pressing foot, a front pressing foot, an air blowing plate, an exhaust fume collecting hood, a smoke dust purifying machine, a vertical air curtain, a transverse air curtain and a side shaft protection air nozzle. A front pressing foot and a rear pressing foot in the welding clamp are both of a cavity structure, plugs are arranged at the two ends of the front pressing foot and the rear pressing foot, an air blowing plate and an exhaust fume collecting hood are installed on the two sides of the clamp respectively, the welding fume absorbing effect is improved in the mode of central air blowing and two-side air suction, and meanwhile, splashing matter is prevented from moving upwards through combination of side shaft shielding air, transverse air curtains and vertical air curtains. From the angle of smoke dust and splash suppression during welding of the large-breadth plate, some optimizati
