Mounting-hanging protective clamp for hard anodization and hard anodization treatment method

Abstract

The invention discloses a mounting-hanging protective clamp for hard anodization of a front casing of an aero-engine and a hard anodization treatment method for the front casing of the aero-engine. The mounting-hanging protective clamp for hard anodization of the front casing of the aero-engine comprises a bottom sealing plate, a supporting rod, an upper cover plate, a fastening piece and a conductive hook, wherein the bottom sealing plate is used for seal-covering an opening in the small end face of the front casing; the supporting rod is fixedly connected to the face of the bottom sealing plate; the upper cover plate is connected to the supporting rod in a sleeving mode for seal-covering an open hole in the large end face of the front casing; the fastening piece is used for forcing the bottom sealing plate and the upper cover plate to be oppositely compressed on openings in the two ends of the front casing; and the conductive hook is fixedly connected to the free end of the supporting rod and used for hanging the whole mounting-hanging protective clamp for hard anodization in a hard anodization electrolyte solution. The mounting-hanging protective clamp is high in strength and good in conductivity and airtightness; the machining problem of development of critical parts on the aero-engine is solved, and it is guaranteed that development of novel aircrafts is carried out smoothly.

Description

technical field [0001] The invention relates to the technical field of local hard anodizing treatment of thick and heavy parts of aero-engines, in particular to a hard anodized mounting protection fixture for the front casing of an aero-engine. In addition, the present invention also relates to a hard anodizing treatment method for the front case of an aero-engine including the above-mentioned hard anodized mounting protection clamp for the front case of an aero-engine. Background technique [0002] Parts that need to be hard anodized should be hung with aluminum wire, titanium wire, general or special fixtures before hard anodizing, and the appropriate fixture should be selected according to the volume, weight, shape and other special requirements of the parts. To play the role of conduction, support and protection. However, most of the hard anodized parts are small in size, light in weight, simple in shape and structure, and the surface protection of non-hard anodized is ...
