Abstract

The invention discloses a paint layer vibration polishing protection clamp for vane fan-shaped assemblies. The paint layer vibration polishing protection clamp comprises a horizontal mounting rod, a plurality of horizontal supporting rods and a plurality of longitudinal circular rings. The longitudinal circular rings are connected through the horizontal supporting rods to form a cylindrical cage-type structure. The vane fan-shaped assemblies are fixed to the mounting rod in the cage-type structure and make spiral movement in the three-dimensional direction along with abrasives in a working cavity of a vibration polishing machine, and the cage-type structure effectively prevents the scratching and bumping between the vane fan-shaped assemblies. Meanwhile, the abrasives are machined through the gap between clamp structural members, and the free flowing of the fan-shaped assemblies is not affected.

Description

【Technical field】

[0001] The invention belongs to the field of manufacturing blades of aero-engine compressors, and relates to a vibrating and light-decorating protective fixture for the paint layer of a fan-shaped component of a blade. 【Background technique】

[0002] At present, the high-voltage stator fan-shaped assembly, the blade material is martensitic stainless steel, and the surface of the blade body is coated with a layer of high-temperature resistant enamel MSRR9140 (Sermetel'W'-A). The blade assembly needs to be vibrated and polished to improve the paint layer of the blade body. The surface roughness is within 40μin.

[0003] In the process of processing, due to the large size and heavy weight of the fan-shaped components of the blade, during the three-dimensional spiral trajectory movement in the working chamber of the vibrating finishing machine, scratches and bumps inevitably occur between the components, resulting in the appearance of the surface paint layer. ...
