Tool for overall assembling welding of engine outer ring assembly

Abstract

A tool for overall assembling welding of an engine outer ring assembly comprises a base plate, a positioning ring, a pressing plate, a main expansion block, an auxiliary expansion block, a pressing cover, a screw rod, a guide plate, a spring, a rubber mat, a locking nut, an end cover nut, a shoulder nut, a guide column, a cone, a pipe connecting nozzle, an air guide pipe and an air nozzle. By means of the tool, two circular welding seams of the engine outer ring assembly and three groups of mounting seat welding seams can be integrated in one device for limiting machining, so that the number of tools required in the machining process is greatly reduced, and the machining cost is greatly reduced; meanwhile, one-time clamping machining is achieved, error accumulation caused by repeated clamping is avoided, clamping positioning is accurate, rapid and stable, dismounting is convenient and rapid, meanwhile, the error prevention effect is achieved, the conditions of wrong mounting, neglected mounting and the like are avoided, and the machining efficiency is greatly improved; and in addition, the device can achieve manual welding and automatic welding expansion, and meanwhile the multi-application requirements of products are met.

Description

technical field [0001] The invention relates to a frock for overall assembly and welding of an engine outer ring assembly. Background technique [0002] like Figure 7-8 As shown, it is a schematic diagram of the structure of the outer ring assembly of an aero-engine. It is mainly composed of a large-diameter sheet metal forming cylinder, a small-end mounting edge, and a large-end mounting edge. After welding, the bottom hole of the mounting seat is cut on the cylinder wall and assembled Solder several mounts. In the process of product manufacturing, there are some problems in the assembly and processing of this component. The mounting bases are dense, the number of welds is large and the distance is close, the parts are deformed after welding, and the workload of post-machining correction is very large. Processing progress. Because the piece is still in the current status of manual assembly and welding, there is no assembly fixture, the fixture design is difficult, the de...

Problems solved by technology

In the process of product manufacturing, there are some problems in the assembly and processing of this component. The mounting bases are dense, the number of welds is large and the distance is close, the parts are deformed after welding, and the workload of post-machining correction is very large. Processing progress

Because the piece is still in the current status of manual assembly and welding, there is no assembly fixture, the fixture design is difficult, the demand is large, and the manufacturing cost is high
