Embodiment Construction

[0048] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0049] From figure 1 It can be seen that the adjustment table of this embodiment mainly includes three tables, from top to bottom, the upper table 1, the lower table 5, and the base 6, and also includes a translation adjustment mechanism 1, a height adjustment mechanism set on the three tables. 4 and yaw adjustment mechanism 7. Three high and low pitch adjustment mechanisms 4 are evenly distributed between the upper table 1 and the lower table 5, the lower table and the base are in direct surface-to-surface contact and compression, the translation adjustment mechanism 1 is fixed on the side wall of the upper table, and the yaw adjustment mechanism 7 is partially fixed Part of the side wall of the base is fixed to the side wall of the lower table 5. The translation of the turntable load is achieved by adjusting the translation adjustment mechanism 2, the heigh...

Abstract

The invention discloses a multi-degree-of-freedom high-strength and high-precision adjusting table suitable for a wind tunnel environment, which is used in the wind tunnel environment, has large bearing capacity, can be used for precisely adjusting optical loads of several tons, is rigidly locked and can be used under vibration or impact, the adjustment and locking of pitching, translation and height are electrically controlled and can be used under closed or severe conditions, the five-degree-of-freedom adjustment of a schlieren primary mirror is met, and the combination of pitching yawing electric adjustment and high-rigidity locking is completed. The system can ensure the position precision and stability of the adjusting table under the working conditions of vibration and wind tunnel airflow impact. The multi-degree-of-freedom high-strength and high-precision adjusting table suitable for the wind tunnel environment successfully solves the problem that the precise adjusting table works in the wind tunnel environment, and can be popularized and applied in the wind tunnel similar environment.

Description

Technical field [0001] The invention relates to the field of optical precision adjustment and alignment, in particular to a multi-degree-of-freedom, high-strength, high-precision adjustment platform in a wind tunnel environment. Background technique [0002] In the field of optical adjustment and alignment, a precision adjustment table with multiple degrees of freedom is essential. Various pose adjustment mechanisms are often used, such as translation tables, lifting tables, rotation adjustment tables, and angular displacement tables. At present, there are many companies dedicated to the research and development of such products in the domestic and foreign markets. These companies have a wide range of products, but Most of its multi-dimensional adjustment platforms are small in size, which is difficult to meet the needs of large-scale and heavy-weight optical systems. [0003] Traditional adjustment tables generally have no locking function or use motor self-locking. This method h...
