The invention discloses a railway vehicle sleeper beam structure and a machining method, and provides a sleeper beam structure which is simple in structure, high in strength and simple in assembling, welding and machining process. By optimizing the profile structure, the welding process and the working procedure, light weight is achieved, the assembly and welding workload is reduced, welding deformation is reduced, and a connecting port of the sleeper beam and a peripheral structure is improved. The sleeper beam structure comprises a left sectional material, a right sectional material, a cover plate, an air spring seat, an air spring pipe and a lining, wherein the left sectional material and the right sectional material are integrated with a plurality of mounting interfaces and welding structures, each mounting interface comprises a floor interface, a traction beam interface and a cover plate interface, the left sectional material and the right sectional material on the lower surface are directly connected through a double-sided V-shaped welding seam, a middle cover plate is not arranged, and a stiffening beam is not arranged between the left sectional material and the right sectional material, so that the welding amount and the welding deformation are reduced; the upper part is connected by the cover plate so as to realize the assembly of the air spring seat and the air spring pipe; and the air spring seat and air spring connecting surface is installed through a stainless steel shaft sleeve cold pressing technology, and the reliability of the sealing structure is guaranteed.
