The invention provides a fixture structure for machining a large thin-wall annular part, which can solve the problem that fixture structure of a traditional annular part is easy to deform after clamping the thin-wall annular part . The fixture structure for machining the large thin-wall annular part can effectively clamp parts and also ensure the machining quality and precision of the parts. The fixture structure for machining the large thin-wall annular part comprises a fixture body and is characterized in that the center of the fixture body is provided with a circular boss, the fixture body is provided with a pressing plate along the circumference, and the pressing plate is sleeved on the upper surface of an annular part to be machined outside the circular boss from the upper part in a compacting manner.
Description
technical field [0001] The invention relates to the field of tooling for processing large ring parts, in particular to a fixture structure for processing large thin-walled ring parts. Background technique [0002] A large annular thin-walled part for aero-engines, the cross-sectional structure of which is shown in figure 1 , the wall thickness is only 7.8mm. When the traditional ring parts are processed by surface CNC milling, the parts are usually clamped by the inner radial chuck and the outer clamp body of the ring parts. However, for thin-walled parts, the above-mentioned traditional radial The fixture structure of the chuck and the external clamp body structure is easy to cause radial deformation of the part, thereby affecting the processing quality and precision of the part. Contents of the invention [0003] In view of the above problems, the present invention provides a fixture structure for processing large-scale thin-walled ring parts, which can solve the proble...
