Abstract

The invention discloses a jet nozzle fast installing tool and a using method. The tool comprises a base plate, a positioning and pressing assembly and a bypass duct case bush hole simulation assembly;the positioning and pressing assembly is installed on the base plate, the base plate is positioned and fixed on the mounting edge of a gas compressor case through the positioning and pressing assembly; the bypass duct case bush hole simulation assembly comprises a guide plate, a simulation block and a guide limiting bolt, the guide plate is fixedly connected to the base plate, the simulation block can slide along the guide plate, a simulation bush hole is formed in the top end of the simulation block; the positioning and pressing assembly comprises a pressing plate, a stud, a bush, a spring,a nut and a positioning pin, the stud is fixedly arranged on the base plate through the bush, the nut, the pressing plate and the spring are sequentially arranged on the stud in a sleeving mode, the positioning pin is fixed on the base plate and is in insertion fit with a mounting hole of the mounting edge of the gas compressor case. The method comprises the following steps that firstly, the mounting edge of the gas compressor case is clamped between the pressing plate and the base plate so as to complete tool fixing, then the position of the simulation block is adjusted, meanwhile, the position of a jet nozzle is adjusted until the jet nozzle can accurately penetrate through the simulation bush hole.

Description

technical field [0001] The invention belongs to the technical field of aero-engine component manufacturing, and in particular relates to a jet nozzle quick installation tool and a using method. Background technique [0002] The jet nozzle is located at one end of the curved pipe, and the mounting seat at the other end of the curved pipe is located outside the compressor casing, and the jet nozzle at one end of the curved pipe needs to accurately pass through the bushing hole of the outer casing. [0003] Since the installation sequence of the outer culvert casing is later, the installation seat on the compressor casing has been blocked by other pipelines at this time, so it cannot be adjusted. If the installation position of the jet nozzle is not accurate, the outer culvert casing cannot be installed Or there is installation stress. For this reason, the previously installed parts can only be dismantled and then reassembled, which will inevitably consume more manpower and tim...
