Damping device for aero-engine thin-wall cartridge receiver part internal shape processing

Abstract

The invention belongs to the technical field of an aero-engine cartridge receiver part processing tool and particularly relates to a damping device for aero-engine thin-wall cartridge receiver part internal shape processing. The damping device for aero-engine thin-wall cartridge receiver part internal shape processing comprises a pedestal, a supporting column, a limiting pressure assembly and a gas damper; the supporting column adopts an annular tubular structure; the supporting column is arranged on the pedestal; the axis of the supporting column is vertical to the plane of the pedestal; thelimiting pressure assembly is detachably arranged at the top of the supporting column; and the gas damper is arranged on the inner surface of the supporting column. The damping device is simple in structure and convenient to manufacture and operate, and can effectively reduce the processing cost of parts; meanwhile, in the use process of the damping device, the damping device can effectively improve the rigidity and the stability of the parts in the internal shape processing process, can guarantee the processing quality of the parts and can improve the processing efficiency.

Description

technical field [0001] The invention belongs to the technical field of machining tooling for aero-engine casing parts, and in particular relates to a vibration damping device used for machining the inner shape of aero-engine thin-walled casing parts. Background technique [0002] In the prior art, when machining the inner shape of an aero-engine annular thin-walled part, due to the poor rigidity of the part, the torque generated by the cutting force of the tool will cause the part to twist, bend, shear and other deformations, and during the processing , the parts will also produce severe vibrations, which will easily damage the parts during processing, thus making the processing of the parts more difficult. Therefore, a shock absorbing device that can facilitate the internal processing of thin-walled casing parts of aero-engines is provided , is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0003] In order to solve the ...
