specific Embodiment approach 1

[0014] Specific implementation mode 1. Combination Figure 1 to Figure 4 Describe this embodiment, the main mirror mandrel mechanism of the telescope based on the principle of static pressure, including the mandrel pressure block 1, the inner pressure plate 2 of the upper film, the outer pressure plate 4 of the upper film, the outer ring of the mandrel 5, the inner hexagonal plunger 6, Mandrel inner ring 9, lower film outer pressure plate 10, rolling film 11, lower film inner pressure plate 12 and mandrel column 13. The mandrel assembly is mainly composed of a mandrel inner ring 9 , a mandrel outer ring 5 and a mandrel column 13 . Wherein the mandrel outer ring 5 is in contact with the middle hole of the primary mirror 1, and the two are bonded together by glue. The mandrel column 13 is mounted on the mirror chamber 14 by screws, and the mandrel inner ring 9 is fixed on the mandrel column 13 by the mandrel pressing block 1 . The mandrel inner ring 9 and the mandrel outer rin...

specific Embodiment approach 2

[0016] Specific embodiment two, combine image 3 and Figure 4 Illustrate this embodiment, this embodiment is the oiling method of the telescope main mirror mandrel mechanism based on static pressure principle described in specific embodiment one, this method realizes through the following process:

[0017] First place the mandrel mechanism horizontally, remove the inner hexagonal plunger 6, and then pass image 3 Fill oil at the oil injection input port given in , the low temperature hydraulic oil flows upward gradually through the lowest point, and finally flows out from the oil injection output port. After filling up, at first the hexagonal plunger 6 of the oil injection output port is screwed into the mandrel outer ring 5, and the oil injection output port is sealed.

[0018] Then the mandrel mechanism is rotated and the original oil injection inlet is placed upwards. After standing for a period of time (generally about seven days), the oil injection inlet is also sealed...

Abstract

The telescope main mirror mandrel mechanism and oiling method based on the principle of static pressure involves a precision mechanical device that solves the problem that the existing telescope main mirror mandrel cannot be completely decoupled from the axial support. The mandrel mechanism consists of a core Shaft pressure block, upper film inner pressure plate, closed chamber, upper film outer pressure plate, mandrel outer ring, inner hexagonal plunger, mandrel inner ring, lower film outer pressure plate, rolling film, lower film inner pressure plate, core Shaft column composition. The inner ring of the mandrel, the outer ring of the mandrel and the rolling film together form a closed chamber, which is filled with low-temperature hydraulic oil, and the hydraulic chamber serves as the radial support of the primary mirror. The invention can be used for the radial support of the main mirror of the telescope. When the primary mirror points to the vertical direction, the weight of the primary mirror is completely borne by the axial support, and when the primary mirror points to the horizontal direction, the weight of the primary mirror is completely borne by the spindle mechanism. Therefore, it can be ensured that the axial support and the mandrel mechanism of the primary mirror can be completely decoupled in the two states without interfering with each other, and the primary mirror always maintains an ideal supporting effect.

Description

technical field [0001] The invention relates to a precision mechanical device, in particular to a telescope main mirror mandrel mechanism and an oiling method based on the principle of static pressure, which is suitable for the requirement of a radial support mechanism decoupling the telescope main mirror from the axial direction. Background technique [0002] The primary mirror of a telescope is the largest optical component of the telescope system, and the supporting effect of the primary mirror has a great influence on the imaging quality of the telescope. The support of the primary mirror is generally composed of axial support and radial (or lateral) support. A good support system requires that the axial and radial supports are completely decoupled and do not interfere with each other. The mandrel mechanism is a commonly used radial support mechanism for the primary mirror. The common mandrel mechanism is composed of the mandrel outer ring, the mandrel inner ring and the...
