Embodiment Construction

[0027] see figure 1 As shown, an assembly diagram of a support device used for brazing dense arrays of superalloy thin-walled capillaries of the present invention. It is an arc-shaped piece. The supporting device is mainly composed of three parts: a chassis part, a second tube positioning part and a separator positioning part. The position connection relationship between them is: the positioning part of the secondary tube and the positioning part of the partition are located above the chassis part and connected by threads.

[0028] The chassis part includes a positioning chassis 1 . The structural form of positioning chassis 1 is shown in figure 2 , which can be remanufactured by disc machining: first, the shape of the positioning chassis 1 is cut with the disc axis as the origin coordinate; and then 8 stepped grooves are processed along the thickness direction of the positioning chassis 1. The stepped groove is processed in two steps: the first step is to process a stepp...

Abstract

The invention relates to a supporting device for superalloy thin-wall thin glass pipe dense array brazing. The supporting device is composed of a chassis part, a two-stage pipe positioning part and apartition positioning part; a chassis comprises a positioning chassis; the disc axis is used as an origin coordinate, and the shape of the positioning chassis is cut; according to the arc configuration of thin-wall thin glass pipe distribution, eight ladder type grooves are machined in the thickness direction of the positioning chassis; two-stage pipe positioning comprises a two-stage pipe stand column, a two-stage pipe fixation screw, two-stage pipe stand column fixation and a two-stage pipe positioning fixation screw; the stand column and the stand column fixation are connected through the fixation screws; the connected structure is fixed to the positioning chassis through the positioning fixation screw; the partition plate positioning comprises partition plate stand column fixation, a partition plate, a partition plate stand column, a partition plate fixation screw and a partition plate positioning fixation screw; the partition plate is sandwiched between the partition plate stand column and the partition plate stand column fixation, and the upper end and the lower end are fastened by the partition plate fixation screw; and the connected structure is fixed to the positioning chassis through the partition plate positioning fixation screw.

Description

technical field [0001] The invention relates to a supporting device for brazing dense arrays of high-temperature alloy thin-walled capillary tubes, which is suitable for providing precise positioning for brazing of arc-shaped distributed thin-walled capillary tube rows. It belongs to the field of aerospace science and technology. Background technique [0002] The key to strong precooling hypersonic flight power technology lies in the preparation of high-efficiency super precooler, and the preparation of high-efficiency super precooler is based on the preparation and connection of superalloy thin-walled capillary tubes. The brazing of dense arrays of superalloy thin-walled capillary tubes has therefore become the top priority of the entire strong pre-cooling hypersonic flight power technology research and development. [0003] The precooler in the strong precooling hypersonic flight power system mainly consists of a core heat exchange unit composed of a dense array of supera...
