The novel stamping and welding front auxiliary frame comprises a longitudinal beam body and a cross beam body, the cross beam body is arranged on the inner side of the longitudinal beam body, the longitudinal beam body comprises a longitudinal beam upper plate and a longitudinal beam lower plate, a T-shaped sleeve is arranged on the lower surface of a vehicle body gasket, welding seams are arranged on the outer side of the vehicle body gasket and the outer side of the T-shaped sleeve, and the welding seams are welded to the longitudinal beam upper plate. The longitudinal beam body is fixedly connected with the cross beam body, the T-shaped sleeve is in lap joint and welding with the longitudinal beam lower plate, and the vehicle body gasket is fixedly connected with the longitudinal beam lower plate in a welding mode. The novel stamping and welding front auxiliary frame has good stability, the rigidity and durability of a vehicle body sleeve installation point are integrally improved, the product reliability is guaranteed, the Z-direction rigidity of a vehicle body sleeve can be greatly improved, and the connection strength and rigidity are improved. The T-shaped sleeve and the longitudinal beam vehicle body gasket are adopted for connection and fixation at the whole vehicle body sleeve installation point, and the durability is better.
