Abstract

The invention discloses a device for welding and assembling installation seats on an aero-engine combustor diffuser case. The device comprises a base and six kinds of supporting base assemblies which are fixedly arranged on the base and used for positioning the six kinds of installation seats on the diffuser case correspondingly. Each installation supporting base assembly comprises a supporting base body fixed to the base, a supporting pin, a lock screw, a baffle and a jacking screw, wherein the supporting base body is provided with a pin hole matched with the supporting pin, and a threaded hole which is matched with the lock screw to form a lock thread pair so that the supporting pin can be fixed into the pin hole; the supporting pin is provided with a matching section matched with an installation hole of the corresponding installation seat; the baffle is fixed to the end of the supporting pin through a threaded structure, located in the wall surface of the diffuser case and provided with no less than two threaded holes matched with the jacking screw; and the installation seats to be welded and assembled are positioned on supporting and positioning structures of the supporting pins through the jacking screws. The device provided by the invention is accurate and reliable in positioning, and the problem that hands are burnt is solved.

Description

technical field [0001] The present invention relates to the assembly technology of welding the mounting seat on the diffuser case of the engine combustion chamber in the field of aero-engine combustion chamber manufacturing, more specifically, relates to a method for welding and assembling the mounting seat of the aero-engine combustion chamber diffusion case device. Background technique [0002] The diffuser casing of the aero-engine combustor is an important part of the aero-engine, and its main body is regularly distributed with forty mounting seats for assembling parts such as nozzles, bushings, brackets, etc. These mounting seats are connected to the main body by welding . In the prior art, in the process of welding the mounting bases on the diffuser case of the engine combustion chamber, the positioning method of the mounting bases on the casing is to support each mounting base from the inside by means of a rotary tooling similar in structure to the diffuser case. Th...
