Problems solved by technology

In addition, there are still great difficulties in the processing of slender holes. When the length of the internal flow channel reaches a certain value, process holes need to be installed at both ends of the flow channel at the same time. The increase in the number of process holes and the subsequent welding of the process holes processing, will directly affect the reliability of the rack structure

Embodiment 1

[0065] Such as figure 1 and figure 2 As shown in the figure, it is a structural schematic diagram of the laser selective melting forming frame assembly for the attitude control power system of a certain type of missile weapon. The channel distributor is composed of frame 1, filter device 2, throttle orifice 3 and other parts, and can provide three kinds of working media for each single engine at the same time.

[0066] When designing the frame structure, according to the layout scheme of the single engine, determine the specific structural form of the frame, the mechanical interface connected with the engine and the outer contour size. Compared with traditional mechanical processing methods, laser selective melting forming technology has excellent technical advantages in forming complex structures, and can design the frame structure for maximum weight reduction without increasing processing difficulty. Generally, only 90° right-angle transition connection can be selected fo...

Abstract

The invention provides a frame assembly based on laser selective melting forming technology, comprising: a frame (1), a filter device (2), and a throttling orifice plate (3); the frame (1) includes an internal flow channel; the filter The device (2) is arranged at the beginning of the internal flow channel of the frame (1); the throttling orifice plate (3) is arranged at the end of the internal flow channel of the frame (1). The invention can realize the supply and flow adjustment of the working medium of multiple engines at the same time; reduce the number of working medium conveying pipelines in the final assembly of the attitude control power system, greatly reduce the number of welds in the system, and improve the reliability of the system seal; the system The reduction of pipelines is conducive to improving the anti-vibration ability of the system structure; it reduces the production labor during the integrated assembly of system products, and improves the efficiency of mass production of the attitude control power system.

Description

technical field [0001] The invention relates to the technical field of liquid posture control power systems, in particular to a frame assembly based on laser selective melting forming technology. In particular, it relates to the frame component integration technology for providing installation structure and working medium delivery for multiple engines manufactured by laser selective melting and forming technology. Background technique [0002] Structural integrated design is an important design principle in the aerospace field. Under the current conditions of demanding weight requirements and space layout requirements for the liquid attitude control power system, the integrated design of the engine can better meet the design requirements of the whole bomb. In addition, the frame Combining the installation structure and the delivery function of the working medium can reduce the number of system pipelines, reduce the workload of system assembly, and improve production efficien...
