Abstract

The two-dimensional precise angle timer for the second crystal of double crystal monochromator belongs to regulating mechanism. The upper support board is connected first to the positioning board and then to the frame, one linear stepped motor with coder is positioned via the head screws to the upper support board, one other linear stepped motor with coder is fixed to the middle support board via one tensile spring assembly and the head screws, the middle support board and the lower support board are connected via two flexible hinge assemblies, the second crystal is mounted onto the regulating board via one other tensils spring assembly, and the two crystal holding boards are connected to the lower support board.

Description

technical field [0001] The invention relates to an angle precision fine-tuning device, in particular to a 2-dimensional angle fine-tuning device for the second crystal of a double-crystal monochromator, belonging to the mechanical field. Background technique [0002] At present, the fine-tuning method of the second crystal of the twin-crystal monochromator used in the synchrotron radiation beamline mainly adopts an adjustment device composed of a stepping motor, a screw drive, an elastic screw, and a three-point spherical stud support. The number of parts is large, the structure is relatively complex, and the precision is low, and the fine-tuning sensitivity is low. In recent years, flexible hinges have been widely used in micro-precision machinery. It has the advantages of no mechanical friction and no need for lubrication. This is very important for parts that work in high-vacuum environments like twin-crystal monochromators. The present invention will A special flexible ...
