The utility model relates to the technical field of hinge bodies, and discloses a
machining part of a hinge body, which comprises a fixing plate, the bottom of the fixing plate is fixedly connected with two fixing seats, the inner walls of the two fixing seats are provided with oil inlet holes, the inner walls of the fixing seats are provided with mounting holes, and the oil inlet holes are communicated with the mounting holes. A plurality of oil inlet holes are formed in the top of the fixing plate, a plurality of oil outlet holes are formed in the inner wall of each oil inlet hole, the oil outlet holes are communicated with the mounting holes, a mounting seat is arranged at the top of the fixing plate, a positioning groove is formed in the top of the fixing plate, and a limiting groove is formed in the top of the fixing plate. Lubricating oil is added into the hinge shaft through the oil inlet hole and then is uniformly distributed in the mounting hole through the oil outlet holes, so that the hinge shaft is lubricated, the
friction force between the hinge shaft and the inner wall of the mounting hole is reduced, the service life of the hinge body is prolonged, the hinge shaft is conveniently and quickly lubricated, the operation is simple and convenient, and the anti-
rust effect is also achieved; and the durability of the hinge body is further improved.
