Abstract

The invention discloses a vacuum laser welding device. The vacuum laser welding device comprises an equipment base frame, wherein a Z-axis lifting machine is arranged on the equipment base frame, a laser welding gun is arranged on the Z-axis lifting machine, a first fixation plate and a second fixation plate are arranged on the base frame, a pressure maintaining air cylinder is arranged at the topend of the first fixation plate, a first stopping plate and a second stopping plate are arranged between the first fixation plate and the second fixation plate, guide shafts are arranged on the firstfixation plate and the second fixation plate, a vacuum box is fixed to the first fixation plate, a servo motor is arranged on the second baffle, the output end of the servo motor runs through the second baffle and is connected with a coupler, and the pressure maintaining air cylinder is arranged at one end of the coupler. The vacuum laser welding device is simple in structure and convenient to weld, contact with air is reduced, oxidation of the product is lowered, welding is more uniform, and the product is prevented from being deformed or cracked.

Description

technical field [0001] The invention relates to the technical field of vacuum equipment for laser welding, in particular to a vacuum laser welding device. Background technique [0002] As an efficient, high-quality and green processing tool, laser welding is widely used in various fields of industrial production such as ships, rail transit, aerospace, etc. The penetration depth, that is, the depth of the molten pool, is one of the most important indicators for evaluating its quality. In recent years, with the emergence of high-power fiber lasers and disk lasers, vacuum laser welding technology has also developed rapidly. The vacuum environment has a good effect on suppressing plasma. Under the same power, laser welding in atmospheric environment can be obtained. 2 ~3 times the penetration depth at the seam, or the same penetration depth can be achieved with less laser power, and the seam is uniform and beautiful [0003] In the prior art, laser welding is affected by comp...
