This invention provides a follow-up clamping device for providing vortex gas to a laser welding head to protect the workpiece being welded. The follow-up clamping device includes: a clamping body having a conical inner cavity; a connecting member, one end of which is connected to the laser welding head; and an annular gas supply member, through which gas is introduced from the large opening side of the conical inner cavity, converges and forms a vortex-like converging airflow within the conical inner cavity, and is then ejected from the small opening side of the conical inner cavity, suitable for spraying towards the workpiece being welded. This invention solves the problems of unstable gas protection and the existence of protection dead zones in existing technologies, as well as the problem of severe plasma shielding effects affecting welding depth and energy transmission in existing technologies. It also solves the problem of existing laser welding clamping mechanisms obstructing airflow and causing protection blind zones.

This utility model relates to the field of welding in mechanical manufacturing, and more specifically, to a box-type assembly clamping fixture. This utility model includes a clamping component and a clamping component. The clamping component has several positioning holes, and the clamping component includes a pry bar and a pressure head. One end of the pressure head is a working end, and the other end is a connecting end fixed to the pry bar. The working end of the pressure head consists of symmetrically distributed tubes that are inserted into the positioning holes of the clamping component to achieve a snap-fit ​​connection between the clamping component and the clamping component. Through the snap-fit ​​connection between the clamping component and the clamping component, the flange plate of the box-type component to be welded is clamped and fixed, thereby providing a strong and controllable clamping force during the assembly and welding of the box-type component, ensuring precise positioning and tight fit between the flange plate and the web plate, and effectively resisting welding deformation.
