Assembly welding method of fan-shaped block welding assembly

Abstract

The invention discloses an assembly welding method of a fan-shaped block welding assembly. By using a clamp positioning adjustable structure, welding deforming control is achieved, gap coping of blades and inner-and-outer templates is convenient, and specifically, the bottom face of a T-shaped plate is positioned through a T-shaped plate right positioning sliding seat, and the side faces of the T-shaped plate are positioned through a T-shaped plate side face positioning block; the T-shaped plate and the positioning sliding seats on the two sides of the T-shaped plate are stored in a fixed base body structure which is composed of a bottom plate, a left angle seat and a right angle seat, the positions are well adjusted, and pressing and fixing are conducted by using an upper face pressing plate and side face pressing plates; and the bottom face and an outer arc of a runner plate are positioned by using a runner plate right positioning sliding seat. The assembly welding method of the fan-shaped block welding assembly has the advantages that (1), machining efficiency is improved; and (2), the economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of aero-engine manufacturing, in particular to a method for assembling and welding processing of sector block welding components in parts of an aero-compressor. Background technique [0002] The assembly and welding of fan-shaped block welding components has always been a difficult point in the welding and assembly of fan-shaped blocks. It involves the positioning and assembly of six part numbers. Each part has a large margin, and there are 11 blades among them. The blades are between the T-shaped plate and the flow channel plate. , Gap grinding is carried out before assembly, and the precision of the cavity after welding is required to be high (±0.1). [0003] Assembling and welding of fan-shaped block welding components at the compressor part usually uses fixtures to fix the positioning of the T-shaped plate and the inner runner plate to ensure the positional accuracy between the two, manually test the bla...

Problems solved by technology

[0003] Assembling and welding of fan-shaped block welding components at the compressor part usually adopts fixture fixed positioning T-shaped plate and inner flow channel plate to ensure the position accuracy between the two, manual trial assembly of blades, grinding of blades and T-shaped plate and flow channel Install the repaired blades one by one, and use the energy storage spot welding machine to spot weld the blades, the T-shaped plate and the inner runner plate. Since the fixture positioning T-shaped plate and the inner runner plate cannot be adjusted, welding The margin of the front part is large, which leads to uncontrollable margin after welding. Once the gap between the blade and the T-plate and the runner plate is adjusted, the fixture is clamped once. The operation is time-consuming and laborious, and the repair rate after welding is high.
