Embodiment 1

[0020] see Figure 1-Figure 2 As shown, a support platform for a low-temperature vacuum chamber, which includes a vacuum cryogenic chamber 1, four support legs 2, and an optical platform 3, the optical platform 3 is accommodated in the vacuum low-temperature chamber 1, each One end of the supporting leg 2 is fixed on the lower surface of the optical table 3, and the other end of the supporting leg 2 passes through the wall of the vacuum low-temperature cooling chamber 1 and touches the ground;

[0021] The outer wall of each supporting leg 2 exposed outside the vacuum low-temperature cooling chamber 1 is provided with a sealing bellows 4, one end of the sealing bellows 4 is in contact with the outer wall of the vacuum low-temperature cooling chamber 1, and the other end of the sealing bellows 4 is in contact with the outer wall of the vacuum low-temperature cooling chamber 1. connected to the ground;

[0022] A temperature sensor 5 is fixedly installed at the center of the lo...

Embodiment 2

[0027] A support platform for a low-temperature vacuum chamber, which is different from Embodiment 1 in that the upper surface of the first heat-insulating metal cover 9 and the upper part of its circumferential side wall are sleeved with a second heat-insulating Pad 8, the second heat insulating pad 8 is externally contacted with a second heat insulating metal cover 9, the second heat insulating metal cover 9 is the same shape as the first heat insulating pad 8, and the size matches, and the second heat insulating metal cover The lower end of the cover body 9 extends downward, and is suspended adjacent to the inner wall of the vacuum low-temperature cold chamber 1, and the inner surface of the second heat-insulating metal cover body 9 is polished.

[0028] The annular heating plate 6 is arranged at the middle position between the temperature sensor 5 on the lower surface of the optical platform 3 and the outer edge of the lower surface of the optical platform 3 .

Abstract

The invention relates to a supporting platform for a low-temperature vacuum cold cabin. The supporting platform comprises the low-temperature vacuum cold cabin, four supporting legs and an optical platform. The optical platform is contained in the low-temperature vacuum cold cabin, one end of each supporting leg is fixed to the lower surface of the optical platform, the other end of each supporting leg penetrates the low-temperature vacuum cold cabin and contacts with the ground, a sealing corrugated pipe sleeves the outer wall of each supporting leg exposed outside the low-temperature vacuum cold cabin, a temperature sensor and an annular heating element are mounted on the lower surface of the optical platform and electrically connected with a temperature controller through cables, a first heat insulation mat is arranged on the upper surface of the optical platform, a first heat insulation metal cover is connected outside the first heat insulation mat in a contacting manner, and the lower end of the first heat insulation metal cover is connected onto the inner wall of the low-temperature vacuum cold cabin in a suspended manner. The supporting platform is low in production cost and convenient and rapid to manufacture, and solves the problem that a past supporting platform adjusted at normal temperature deforms due to environmental temperature change.

Description

technical field [0001] The invention relates to a support platform, in particular to a support platform for a low-temperature vacuum chamber. Background technique [0002] The support platform is installed in the low-cold environment simulation cabin, and its function is to provide installation positions for the photoelectric components tested in the low-cold environment simulation cabin; After the change, deformation will occur, and the precision of the optical components is very high, often a change of a few millimeters will have a great impact on the imaging quality. [0003] At present, the existing support platforms used in the low-cold environment simulation cabin either do not consider the deformation effect of temperature changes, or use Invar Steel (transliteration of Invar Steel), which is a kind of iron-nickel alloy, and its composition is nickel 36 %, iron 63.8%, carbon 0.2%, the biggest feature of this material is that the deformation with temperature is extrem...
