Movable support capable of adjusting test piece angle in vacuum container

Abstract

The invention discloses a movable support capable of adjusting the test piece angle in a vacuum container, which comprises a lower support body, an upper support body, an upper flange and a lower flange, wherein the lower support body and the upper support body are butted to form a square frame by hollow pipes, reinforcing ribs are arranged at four inner corners of the square frame, the ring-shaped upper flange and the ring-shaped lower flange are arranged on the reinforcing ribs on the upper support body and the lower support body respectively, and axial positions of the upper flange and the lower flange can be guaranteed to be unchanged by means of opposite rotation and a fixing block, so that the test piece angle is adjusted by means of rotation of the flanges. By the aid of the movable support capable of adjusting the test piece angle in the vacuum container, the problem of angle adjustment of a test piece in the vacuum container is effectively solved, and external heat flow change conditions of the surface of a satellite in orbiting are sufficiently simulated.

Description

technical field [0001] The invention belongs to the field of mechanical design, and in particular relates to a movable support device capable of adjusting the angle of a test piece in a vacuum container. Background technique [0002] Bracket is a relatively common tooling device in the field of mechanical design, widely used in civilian and military fields. Depending on the application requirements, the bracket is generally designed to be fixed. [0003] In recent years, with the development of satellite thermal test technology, the real and accurate simulation of external heat flow is the development trend in the field of satellite ground thermal test, so the solar simulator technology has been developed. In order to apply the solar simulator, it is necessary to design appropriate tooling so that the satellite can rotate at a certain angle in the vacuum container to simulate the change of heat flow outside the surface of the satellite when it is in orbit. [0004] At pres...
