Abstract

The invention provides a sealing device for laser welding, and relates to a sealing structure. The device solves the problems that the multi-position continuous laser welding of structural members cannot be completed and the pressure bearing cannot be realized in the processes of vacuum pumping and argon filling for the existing laser welding by using transparent glass. The device comprises a vacuum chamber and a mounting frame which is fixedly provided with a transparent glass plate, and also comprises an air cylinder fixing seat, a sealing cover plate, N air cylinders, N slide valves and N push rods, wherein the mounting frame which is fixedly provided with the transparent glass plate is inserted into the middle of the upper wall of the vacuum chamber; the N air cylinders are uniformly distributed on the air cylinder fixing seat in the circumferential direction, and the end parts of driving rods of the N air cylinders are fixedly mounted on the sealing cover plate; the N slide valves are uniformly distributed on the edge of the mounting frame which is fixedly provided with the transparent glass plate, each slide valve comprises a valve rod, a valve body and a sealing ring, the sealing rings are fixedly mounted on the valve rods, the valve rods are vertically mounted in the valve bodies in a sliding manner, and the sealing rings are bonded with inner cavities of the valve bodies. The device is used for laser welding.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a sealing device for laser welding. Background technique [0002] When welding metals with strong chemical activity, such as beryllium and zirconium, in order to avoid the adverse effects of water and oxygen in the welding atmosphere on the weld formation and corrosion resistance, a sealed cabin must be used to control the welding atmosphere to achieve good protection. Effect. Conventional vacuum chambers used for laser welding have very strict requirements on the performance and size of the light-transmitting glass plate due to the excessive pressure difference between the inside and the outside. Although the small size of the light-transmitting glass can solve the problem of pressure bearing, it cannot complete the multi-position continuous laser of structural parts. welding. However, the large size of the light-transmitting glass may cause damage due to excessive pressure during the va...
