A fixture for thin-walled easily deformable squirrel cage parts

Abstract

The invention discloses a fixture for a thin-walled mouse case part liable to deform. The fixture comprises a part locating fixture body (1) and a fixture propping plate (4), wherein an upper end face (1-1) of the part locating fixture body (1) is a circular plane; bolt holes (1-3) are distributed in the circumferential direction of the edge of the upper end face; a cylindrical boss (1-2) is arranged on the upper end face (1-1); the fixture propping plate (4) is a cylindrical plate; a threaded through hole is formed in the fixture propping plate; a propping screw (5) is arranged in the threaded through hole; and the head part of the propping screw (5) is spherical. According to the fixture, during the clamping process, bolts pass through the bolt holes (1-3) to fix the lower part of a mouse cage, and the propping screw (5) is adjusted to be propped against the mouse cage from an inner cavity of the mouse cage through the fixture propping plate (4), so that the part is prevented from deforming due to clamping, the mouse cage part is processed in the fixed state, and the part does not deform due to straining on the condition that ribs of a barrel body are subjected to symmetrical distributed processing.

Description

technical field [0001] The invention relates to a processing fixture for a thin-walled easily deformable squirrel cage part in the field of aero-engine design, and is mainly used for improving the stress of the part and reducing the clamping and processing deformation of the part. Background technique [0002] Such as figure 1 As shown, in aero-engines, various thin-walled cylindrical parts are widely used in engines. The squirrel cage part is a special structural part of the thin-walled cylindrical part. The structure of the part is a thin-walled cylindrical part with many windows around the cylindrical body, and the upper and lower ring parts are supported by very thin squirrel cage bars. Because the squirrel cage window bears do huge wind pressure. Therefore, there are very strict requirements on the layout of the cage strips. There are high requirements on the thickness of the cage strips, the equalization of the window and the surface roughness of the cage strips. M...
