Abstract

The invention relates to the technical field of aero-engines, in particular to a lathe fixture suitable for processing thin-walled ring-block parts, which is used for clamping thin-walled ring-block parts with thin walls that need to be processed. , the fixture is a circular disk surface, and a plurality of independent fixed blocks are evenly and symmetrically arranged on it. All the fixed blocks form a ring that is concentric with the circular disk surface of the fixture; Arrange the same number of unit fixtures as the fixed block, and evenly open square holes at the bottom of the fixed block, corresponding to the position of the unit fixture; each set of unit fixtures includes a pressing platen and a tensioning platen to fix the process edge and thin-walled ring block parts on the fixture in multiple directions . The invention effectively improves the clamping rigidity of the thin-walled ring block type parts by turning, avoids the chattering in the parts processing, reduces the processing deformation, greatly improves the qualified rate of the parts, and saves the cost.

Description

technical field [0001] The invention relates to the technical field of aero-engines, in particular to a lathe fixture suitable for processing thin-walled ring block parts. Background technique [0002] With the deepening of my country's economic construction, rotary products such as aero engines and gas turbines will also be used in large quantities, and thin-walled ring block parts are an indispensable part of these rotary products. Common structural parts occupy an important position in the design and manufacture of aero-engines. At the same time, due to the special shape and complex structure of ring block parts, their wall thickness is usually thin, which leads to difficulties in clamping during part processing, large deformation of parts after processing, and unstable processing quality. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a lathe fixture suitable for processing thin-walled ring block parts,...
