Abstract

The invention relates to a combined machining tool and a combined machining method for a force bearing support plate. The combined machining tool comprises at least two sets of clamping tools, wherein each set of clamping tool comprises a base, a first stand column, a second stand column, a cross beam, a first shape follow-up clamping block and a second shape follow-up clamping block; the first stand columns and the second stand columns are vertically and oppositely arranged on the bases; the two ends of the cross beams are fixedly arranged at the tops of the first stand columns and the tops of the second stand columns correspondingly; and the first shape follow-up clamping blocks and the second shape follow-up clamping blocks are oppositely arranged on the inner sides of the first stand columns and the inner sides of the second stand columns and used for clamping the two sides of the force bearing supporting plate. According to the combined machining tool and the combined machining method for the force bearing supporting plate provided by the invention, the positioning requirement and the rigidity requirement of the force bearing supporting plate in the machining process can be met, the number of tools is reduced, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of aero-engine manufacturing, in particular to a combined processing tool for a bearing support plate and a combined processing method thereof. Background technique [0002] Aeronautical turbofan engine with high bypass ratio (hereinafter referred to as "aero engine") includes fan booster stage, high-pressure compressor, combustion chamber, high-pressure turbine, low-pressure turbine and other components. The box part is used to guide the transition of gas from the outlet of the high-pressure turbine to the inlet of the low-pressure turbine, and install the fixed bearing. figure 1 A schematic structural diagram of an aero-engine interstage casing is shown. As shown in the figure, the interstage casing 100 includes main parts such as an outer casing 101, a bearing support plate 102, an inner casing 103, a bearing seat 104, a rectifying vane 105 in a transition section, and a bearing 106, among which the oute...
