The invention provides a lifting lug with a groove. The lifting lug comprises a lifting lug end part (1) and a lifting lug base. The lifting lug base (2) is a cylindrical component, and a cylindricalgroove (3) is formed in the center circle of the end surface of one side of the cylindrical component. The diameter of the groove (3) is not more than half of the diameter of the end surface of the cylindrical lifting lug base (2), and the depth of the groove (3) does not exceed half of the height of the cylindrical lifting lug base (2). The C-shaped lifting lug end part (1) is fixedly connected to the end surface of the other side of the cylindrical component, and a triangular area is enclosed between the lifting lug end part (1) and the lifting lug base (2) for hanging onboard suspension. The lifting lug with the groove enables materials at the center positions of parts to be well heated during heat treatment to meet the requirements of the heat treatment of the parts.
Description
Technical field [0001] The invention belongs to the field of aviation structure design, and specifically relates to a lifting lug with a groove. Background technique [0002] All airborne suspensions require lugs to be connected to the aircraft pylon. The lifting lugs are generally made of steel. During heat treatment, there will be a phenomenon that the heat treatment of the center part of the part is not thorough, which affects the strength performance of the lifting lugs. Summary of the invention [0003] The purpose of the present invention is to provide a lifting lug with a groove, which overcomes or alleviates at least one of the above-mentioned drawbacks of the prior art. [0004] The object of the present invention is achieved through the following technical solutions: a lug with a groove, comprising a lug end and a lug base, the lug base is a cylindrical member, and a cylindrical groove is opened on one end surface of the member, A C-shaped lifting lug end is fixedly conn...
