HOLE FABRICATING METHOD FOR OVERSIZED ROD MEMBER

WIPO Patent Application WO/2023/155420

A1

Disclosed is a hole fabricating method for an oversized rod member. The method comprises assembling and welding according to design requirements to obtain a box-shaped rod member, the box-shaped rod member comprising a rod member upper cover plate, a first rod member side web plate, a second rod member side web plate, a lower cover plate, a first gusset plate, and a second gusset plate; and drilling a hole group positioning hole of the first rod member side web plate and a hole group positioning hole of the first gusset plate. The hole fabricating method for an oversized rod member provided by the present application changes the working idea that an oversized rod member can only use a rod member three-dimensional scribing sampling drilling method and can solve the problem of an oversized rod member not being able to pass through a numerically controlled machine tool. By means of using a jig for hole fabricating, the difficulty of the three-dimensional scribing sampling drilling method and the limitation of the technical level of an operator, which cause the concentricity of a hole group of the rod member to be out of tolerance, are avoided. The relative precision of the hole group of the rod member is ensured. Furthermore, the efficiency of fabricating holes in a rod member can be increased, and manufacturing costs and working periods are saved.
