Embodiment Construction

[0065] The present invention will be described in detail below in combination with specific embodiments.

[0066] A method for processing an injector partition cavity, comprising the following steps:

[0067] A1. If figure 1 As shown, the annular body 1 is roughly machined with 06Cr19Ni10 material, a number of reference holes are evenly rough drilled on the annular surface, and six water inlet holes are uniformly bored and milled around its circumference; 1 Cut out six fan-shaped grooves and six wedge-shaped vertical grooves on the inner circumference, and process them to form a stop at the notch; use 06Cr19Ni10 material to process and match the fan-shaped grooves, such as figure 2 The six upper cover plates 11 shown and as image 3 The six lower cover plates 12 shown are processed with 06Cr19Ni10 material to match the wedge-shaped vertical groove as Figure 4 The six wedge-shaped inserts 13 are shown; interfaces matching the six wedge-shaped inserts 13 are processed on th...

Abstract

The invention relates to the field of aerospace device processing, and discloses a method for processing an injector partition cavity, which includes the following steps: A1. Cutting out fan-shaped grooves and wedge-shaped vertical grooves on the inner circumference of the annular body; processing the upper and lower cover plates and Wedge-shaped insert, assemble the upper and lower cover plates at the fan-shaped groove, finish the wedge-shaped insert and assemble it at the vertical groove, and vacuum braze to obtain the bulkhead cavity assembly: A2. Assemble the ring groove in the bulkhead cavity Fix and braze the inner circumference of the main body component; wire cut, assemble and braze the hollow plate and corrugated plate to obtain the partition; wire cut the adapter, assemble it with the partition and braze to obtain the honeycomb component: A3. End milling on inserts and ring groove parts to process sinking table, fine milling compensation block; milling square groove in the middle of the reinforcement plate, and milling solder grooves on both sides of the square groove and the outer end face of the reinforcement plate; assemble, fix and braze Weld the diaphragm chamber body assembly, reinforcement plate, honeycomb assembly and compensation block; finish machining after being released from the furnace, and argon arc weld the water joint at the water inlet to obtain the injector diaphragm chamber.

Description

technical field [0001] The invention relates to the technical field of aerospace device processing, in particular to a processing method for an injector diaphragm cavity. Background technique [0002] The partition injector is composed of three parts: oil chamber assembly, water chamber assembly and partition chamber assembly. The chambers are positioned by pins and sealed by copper pads, and the injector is assembled and connected with the combustion chamber by bolts; The clapboard cavity is mainly composed of annular body, ring groove, hollow plate, corrugated plate, adapter, water joint and other parts; among them, the clapboard cavity body assembly is formed after the annular body is processed, and the hollow plate and the corrugated plate are assembled, The diaphragm is formed after brazing, the diaphragm and the adapter are assembled and brazed to form a honeycomb assembly, and the diaphragm cavity body assembly is assembled with the honeycomb assembly and the ring gro...
