Abstract
The invention discloses a turning method for a rubber easy-to-wear ring of a large fan casing assembly. The method comprises the following steps: 1, the rubber easy-to-wear ring is turned on a vertical numerical control lathe; 2, a special clamp is used for auxiliary supporting, and auxiliary supports are installed on the inner side and the outer side of the fan casing assembly; 3, on the premisethat the machining stroke is guaranteed, a low cross beam gear is selected as much as possible, and the stretching-out length of a machine tool ram is reduced as much as possible; 4, aiming at the fact that the upper side and the lower side of the rubber easy-to-wear ring need to be in smooth transition with an aluminum lining plate casing, a cutter used in the machining process needs to meet therequirement for rubber and aluminum alloy at the same time; 5, in the machining process of cutting the rubber easy-to-wear ring, cooling can be conducted in an air cooling mode; and 6, the rubber easy-to-wear ring is machined, a tool microscope is used for checking the blade before machining, and accurate tool setting needs to be conducted after the blade is installed.
Description
technical field [0001] The invention belongs to the technical field of casing processing of large-scale aviation turbofan engines, and in particular relates to a method for turning a rubber easy-wearing ring of a large-scale fan casing assembly. Background technique [0002] Compared with the previous fan casings, the fan casing for a certain type of large turbofan engine is characterized by its large size. The inner diameter of the rubber wear-resistant ring of this part is about φ1800mm, which has the following processing difficulties: [0003] First: The size of the parts is large. The inner diameter of the large fan case assembly is about φ1800mm, the outer diameter is about φ1950mm, and the height is about 1300mm, which leads to poor rigidity of the parts. Due to the large extension length of the machine tool ram, it is easy to produce resonance. [0004] Second: The inner diameter of the rubber easy-wearing ring is about φ1800-φ1840mm, the length is nearly 300mm, and ...
