Abstract

The invention provides a high-stability two-dimensional attitude adjusting mechanism, which belongs to the field of instruments and equipment, and comprises an adjusting table, a base, two linear drivers arranged on the base in parallel, two flexible connecting assemblies arranged between the two drivers, and a lifting device group arranged between the base and the adjusting table, the lifting device set is used for lifting the adjusting table and leaving the adjusting table from the base, and the two linear drivers are used for driving the two flexible connecting assemblies to move in the same direction or in the opposite directions correspondingly, so that the adjusting table is driven to horizontally move in the radial direction or rotate in the axial direction. During use, the lifting device separates the adjusting table from the base through a certain lifting force, mutual friction between the adjusting table and the base is avoided, then the two linear drivers are driven to adjust movement in the same or opposite directions, and therefore translation adjustment of the adjusting table and angle adjustment in a plane are achieved. All motions of the two drivers can be decomposed into superposition of the two motions, and therefore linkage adjustment of the adjusting table in the specific linear direction in the horizontal plane and the angle in the horizontal plane is achieved.

Description

technical field [0001] The invention relates to the field of instruments and equipment, in particular to a high-stability two-dimensional attitude adjustment mechanism. Background technique [0002] In the application of large scientific devices, it is necessary to move the key components to a specific position and adjust the corresponding angle and attitude. For example, in advanced X-ray light sources, it is necessary to use optical components such as deflecting mirrors or KB focusing mirrors to adjust the X-ray angle slightly, and in some cases, it is necessary to translate the optical components out of the X-ray path. For this type of adjustment mechanism, it is usually adjusted by stacking adjustment mechanisms in series, that is, one layer of translation adjustment and one layer of angle adjustment. This increases the transmission of errors to a certain extent, and at the same time, due to the backlash error of the motion adjustment mechanism, it further affects the s...
