Abstract

The invention discloses a milling tool for a cambered-surface thin-wall casing part. The milling tool comprises a tool bottom plate, auxiliary supporting blocks, fixed supporting seats, transverse supporting blocks, adjustable supporting rods and a locking nut; the multiple auxiliary supporting blocks and the multiple fixed supporting seats are installed on the tool bottom plate through bolts; the upper portions and the lower portions of the fixed supporting seats are connected with the transverse supporting blocks, and the transverse supporting blocks are provided with the multiple adjustable supporting rods through nuts; the adjustable supporting rods are connected with the auxiliary supporting blocks in an abutting mode; and effective matching of part inner molded surfaces and clamp auxiliary supporting surfaces is ensured. According to the milling tool, the deformation control effect on the cambered-surface thin-wall casing part is remarkable, the tool is convenient to operate, all mechanisms of the tool are easy to match, the reliability is high, and the tool has a remarkable part deformation control effect.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular designs a milling tool for arc-surface thin-walled casing parts, which belongs to a general jig and is suitable for milling and clamping of arc-surface thin-wall casing parts. Background technique [0002] There are many kinds of materials for casing parts in aero-engines, among which thin-walled casing parts with curved inner surfaces occupy a certain proportion. The wall thickness of such parts is generally between 0.8-2.5mm. Because the materials of such thin-walled parts The removal rate reaches about 90%. Parts are easily deformed during processing. After processing, the wall thickness is likely to be uneven or out of tolerance. The clamping effectiveness of such parts determines the state of such parts after processing. [0003] The invention fully analyzes the surface structure of the part, designs a brand-new clamping support structure, and fundamentally so...
