AI Technical Summary
Technical Problem
In existing technologies, the heat generated during welding of the front beam and reinforcing block of the battery box in new energy vehicles leads to dimensional instability, and the welding process is time-consuming.
Method used
A welding fixture for the front beam assembly of a new energy battery box is adopted. By setting anti-deformation devices at both ends of the front beam, a downward clamping force is applied to the ends before full welding. Combined with support, clamping and clamping devices, the assembly and full welding process of the front beam assembly is realized.
Benefits of technology
It effectively prevents the front beam end from warping, ensures product dimensional stability, shortens welding time, and improves production efficiency.

Abstract
This utility model belongs to the field of welding equipment technology and provides a welding fixture for a front beam assembly of a new energy battery box. The front beam assembly includes a front beam and a reinforcing block. The welding fixture includes a welding platform, a first support device, a second support device, a clamping device, a clamping device, and an anti-deformation device. Two anti-deformation devices are arranged opposite each other to apply a downward clamping force to the ends of the front beam. This utility model prevents the ends of the front beam from warping upwards by applying a downward clamping force to the ends of the front beam through the anti-deformation devices, thereby avoiding or reducing the occurrence of dimensional instability in the final battery box assembly. Furthermore, a single welding fixture can sequentially perform the assembly of the front beam assembly and the full welding after assembly, thus shortening the assembly welding time and improving production efficiency.
