Referring to fig. 1, an embodiment of the application discloses an adjusting mechanism capable of measuring a multi-size spherical surface sample, which comprises a sample table 1, a rotating assembly, a turnover assembly and a linear driving assembly which are sequentially arranged from top to bottom. The upper surface of the sample table 1 is provided with a clamping assembly for clamping a spherical sample. The rotating component is connected to the lower end of the sample stage 1 and is used for driving the sample stage 1 to horizontally rotate. The turning component is connected with the rotating component and used for driving the rotating component and the sample table 1 to turn. The linear driving assembly is connected to the overturning assembly and is used for driving the overturning assembly, the rotating assembly and the sample table 1 to translate in the first direction, the second direction and the third direction and can reciprocate. Referring to fig. 1, the first direction is an X-axis direction, the second direction is a Y-axis direction, and the third direction is a Z-axis direction, i.e., the first direction is perpendicular to the second direction, and the third direction is perpendicular to a plane formed by the first direction and the second direction.
Therefore, the adjusting mechanism realizes multi-dimensional measurement of the spherical surface sample by integrating the sample table 1, the rotating component, the overturning component and the linear driving component. The spherical sample can be fixed to the sample stage 1 by a clamping assembly. The rotation assembly rotates in the horizontal plane to change the horizontal measuring angle of the spherical surface sample. The turnover assembly drives the whole rotation assembly and the sample table 1 to turn over in the vertical direction so as to change the inclination angle of the spherical surface sample. By means of the combined movement of the linear driving components, three-dimensional movement of the sample in space is achieved, and comprehensive and accurate measurement of the spherical sample is guaranteed. The method and the device remarkably improve the flexibility and the comprehensiveness of measurement of the spherical surface sample, can cover more measurement dimensions, further accurately evaluate the shape, the size and the surface quality of the spherical surface sample, and provide reliable data support for subsequent processing or application.

A plurality of fixed hooks 11 and movable hooks 12 are circumferentially arrayed on the sample stage 1 to fix the circumferential side of the spherical sample. In the embodiment, the spherical surface sample is subjected to three-point positioning display by using the double fixed hooks 11 and the single movable hook 12. With one diameter of the sample table 1 as a reference, the two fixed hooks 11 are positioned on the same side of the diameter, so that the spherical sample can conveniently move horizontally and then abut against the fixed hooks 11, and the movable hooks 12 can move and then abut against the surface of the spherical sample from the other side, thereby limiting the spherical sample.

The slide groove 123 is penetrated with a limit bolt 124, the slide block 122 can slide relative to the limit bolt 124, and the limit bolt 124 can limit the slide block 122 after being screwed. The sample stage 1 is provided with a limit hole (simple screw hole structure, not identified in the figure) in threaded connection with the limit bolt 124.
The clamping assembly consists of a fixed hook 11 and a movable hook 12, and the two hooks are arranged on the sample table 1 in a circumferential array. The movable hook 12 is slidably connected with the sample stage 1 through a sliding block 122, and can be fixed through the cooperation of a limit bolt 124 and a limit hole. So that the movable hook 12 can be flexibly adjusted according to the size and shape of the spherical sample, ensuring that the sample is firmly clamped. The stability of the spherical surface sample in the measuring process is ensured, and the measuring error caused by movement or loosening of the sample is avoided. Meanwhile, the adjusting function of the movable hook 12 improves the adaptability of the mechanism to spherical samples with different sizes, and the universality and the practicability of the mechanism are enhanced. The movable hook 12 consists of a hook body 121 and a sliding block 122, and a strip-shaped sliding groove 123 formed on the sliding block 122 allows sliding adjustment on the sample table 1. The limit bolt 124 passes through the chute 123 and is in threaded connection with the limit hole on the sample stage 1, so that the movable hook 12 is fixed. So that the movable hook 12 can be easily adjusted in position as required and ensures its stability during measurement. The cooperation of the stop bolt 124 and the stop hole ensures the stability of the movable hook 12 after fixing, and further reduces the possibility of measurement errors.
