Integrated tooling clamp for welding and heat treatment of thin-wall case and assembling method of integrated tooling clamp

Abstract

The invention discloses an integrated tooling clamp for welding and heat treatment of a thin-wall case and an assembling method of the integrated tooling clamp. The integrated tooling clamp comprisesa base, a positioning block and a gland; a plurality of lower end face pressing mechanisms used for pressing the lower end face of the thin-wall case are uniformly distributed in the circumferential direction of the base; a positioning spigot matched with the lower end face of the thin-wall case is further arranged on the base; the gland is arranged on the periphery of the upper end face of the thin-wall case and is located in an upper spigot of the positioning block, an upper end face pressing mechanism is arranged between the gland and the upper end face of the thin-wall case, and one end ofthe positioning block is arranged on the base through a fixing mechanism; and the other end of the positioning block is connected with the upper end face of the thin-wall case. The deformation of a part in the radial direction in the welding and heat treatment processes can be effectively controlled, and it is ensured that the roundness and flow channel surface runout after welding and heat treatment meet design requirements.

Description

technical field [0001] The invention relates to the technical field of fixtures and fixtures for the manufacture of aero-engine casings, in particular to an integrated fixture for welding heat treatment of thin-walled casings and an assembly method thereof. Background technique [0002] The aeroengine is the heart of an aircraft, and it is a highly complex and sophisticated thermodynamic mechanism that mainly provides the aircraft with the power required for flight. To a certain extent, the level of aero-engine technology directly affects the performance, reliability and economy of the aircraft, and is an important manifestation of a country's technological, industrial and national defense strength. At present, with the development of science and technology, countries all over the world are gradually strengthening the research and development of aero-engines, and the casing is one of the parts of aero-engines. [0003] The outer casing of the air intake load-bearing frame u...

AI Technical Summary

Problems solved by technology

[0004] In the existing design, there is a lack of integrated welding and heat treatment fixtures for titanium alloy thin-walled casings. Generally, the parts are only controlled during the welding process, and the heat treatment process is in a free state, so it is difficult to guarantee the final dimensional accuracy of the parts.
