Abstract

The invention relates to a device for vacuum laser welding and belongs to the technical field of vacuum laser welding. The device comprises a laser welding device (1), a vacuum chamber assembly (2), a vacuumizing assembly (3) and a supporting and clamping assembly (4), wherein the supporting and clamping assembly (4) comprises a chuck body (41), a clamping claw (42) and a fixing support (43). The supporting and clamping assembly adopts the claw on the chuck to clamp a member to be welded, simultaneously a vacuum cavity body is fixed on the chuck body through the fixing support so as to ensure that the member to be welded rotate synchronously with the vacuum cavity under the rotary welding mode of the member to be welded, relative motion of the member to be welded and the vacuum cavity body is eliminated, good sealing effect is ensured, the structure is convenient and fast to assemble and clamp, space utilization rate of the vacuum cavity body is high, and the vacuumizing process consumes short time.

Description

technical field [0001] The invention relates to a laser welding device and a welding method, more specifically, the invention relates to a vacuum laser welding device, which belongs to the technical field of vacuum laser welding. Background technique [0002] With the advancement of industrial technology, the design and manufacture of many new components put forward higher requirements for welding accuracy and working conditions, and some need to be welded under vacuum to ensure the quality of the weld, such as the aerospace industry and new energy storage batteries precision welding. Vacuum laser welding not only avoids the problems of electron beam welding, such as large volume, heavy weight, inconvenient flexible processing and X-ray pollution, but also greatly reduces the occurrence of pore defects during laser welding under protective atmosphere, and improves the laser energy efficiency. Therefore, it is very suitable for the welding of metal materials (such as Al allo...
