[0028] The following is combined with Figure 1 To the attached Figure 4 This application is described in further detail.

[0029] Since the existing technology lacks a multi-dimensional measurement method for spherical samples, in order to further accurately measure the spherical samples. Figure 1 , an embodiment of the present application discloses an adjustment mechanism that can measure multi-sized spherical samples, including a sample stage 1, a rotating assembly, a flipping assembly and a linear drive assembly arranged in sequence from top to bottom. A clamping assembly for clamping a spherical sample is provided on the upper surface of the sample stage 1. The rotating assembly is connected to the lower end of the sample stage 1, and is used to drive the sample stage 1 to rotate horizontally. The flipping assembly is connected to the rotating assembly, and is used to drive the rotating assembly and the sample stage 1 to flip. The linear drive assembly is connected to the flipping assembly, and is used to drive the flipping assembly, the rotating assembly and the sample stage 1 to translate in the first direction, the second direction and the third direction, and can perform reciprocating motion. Reference Figure 1 The first direction is the X-axis direction, the second direction is the Y-axis direction, and the third direction is the Z-axis direction. That is, the first direction is perpendicular to the second direction, and the third direction is perpendicular to the plane formed by the first direction and the second direction.

[0030] Therefore, the adjustment mechanism realizes multi-dimensional measurement of spherical samples by integrating the sample stage 1, the rotating component, the flipping component and the linear drive component. The spherical sample can be fixed on the sample stage 1 by the clamping component. The horizontal measurement angle of the spherical sample is changed by rotating the rotating component in the horizontal plane. The flipping component drives the entire rotating component and the sample stage 1 to flip in the vertical direction to change the tilt angle of the spherical sample. Through the combined movement of the linear drive component, the three-dimensional movement of the sample in space is realized, ensuring comprehensive and accurate measurement of the spherical sample. The flexibility and comprehensiveness of the spherical sample measurement are significantly improved, and more measurement dimensions can be covered, thereby more accurately evaluating the shape, size and surface quality of the spherical sample, and providing reliable data support for subsequent processing or application.

[0031] Reference Figure 1 and Figure 2 Specifically, the sample stage 1 is a disc structure. The clamping assembly includes a plurality of fixed hooks 11 and at least one movable hook 12. The plurality of fixed hooks 11 are connected to the sample stage 1 by bolt connection. The plurality of fixed hooks 11 and the movable hooks 12 are arranged in a circular array on the sample stage 1 to fix the circumference of the spherical sample. This embodiment demonstrates the three-point positioning of the spherical sample with double fixed hooks 11 and a single movable hook 12. Taking one diameter of the sample stage 1 as a reference, the two fixed hooks 11 are located on the same side of the diameter to facilitate the spherical sample to abut against the fixed hook 11 after horizontal movement, and the movable hook 12 can move to abut against the surface of the spherical sample from the other side, thereby forming a restriction on the spherical sample.

[0032] Reference Figure 2 Furthermore, the movable hook 12 includes a hook body 121 and a slider 122. The hook body 121 is arranged at one end of the slider 122 to form an L-shaped structure. The slider 122 is provided with a long strip of sliding groove 123 along its length, and the sliding groove 123 vertically passes through the slider 122. A limiting bolt 124 is passed through the sliding groove 123, and the slider 122 can slide relative to the limiting bolt 124. After the limiting bolt 124 is tightened, the slider 122 can be restricted. A limiting hole (a simple screw hole structure, not marked in the figure) is provided on the sample stage 1 and is threadedly connected to the limiting bolt 124.

[0033] The clamping assembly consists of a fixed hook 11 and a movable hook 12, arranged in a circular array on the sample stage 1. The movable hook 12 is slidably connected to the sample stage 1 via a slider 122 and secured by a stop bolt 124 engaged with a stop hole. This allows the movable hook 12 to be flexibly adjusted according to the size and shape of the spherical sample, ensuring a secure clamping of the sample. This ensures the stability of the spherical sample during measurement and avoids measurement errors caused by sample movement or loosening. Furthermore, the adjustable function of the movable hook 12 improves the adaptability of the mechanism to spherical samples of varying sizes, enhancing its versatility and practicality. The movable hook 12 consists of a hook body 121 and a slider 122. An elongated slot 123 on the slider 122 allows for sliding adjustment on the sample stage 1. Stop bolts 124 pass through the slot 123 and threadably engage the stop hole on the sample stage 1, securing the movable hook 12. This allows the movable hook 12 to be easily adjusted as needed, ensuring its stability during measurement. The cooperation between the limiting bolt 124 and the limiting hole ensures the stability of the movable hook 12 after being fixed, further reducing the possibility of measurement error.

[0034] Reference Figures 1 to 4 Furthermore, the adjustment mechanism also includes a base 2, located at the bottom of the adjustment mechanism for connection to a device or table. The linear drive assembly is connected to base 2. Base 2 serves as the support foundation for the entire adjustment mechanism, providing a stable mounting platform for other components. This enhances the stability and rigidity of the entire adjustment mechanism, ensuring accuracy and reliability during measurement. It also provides the necessary mounting space and support for other components, enabling the entire mechanism to work together efficiently.

[0035] Reference Figures 1 to 4 Specifically, the linear drive assembly includes a first slide 3, a second slide 4 and a third slide 5, which are arranged in sequence from bottom to top. In other embodiments, the positions of the first slide 3, the second slide 4 and the third slide 5 are not fixed and can be combined arbitrarily. The first slide 3, the second slide 4 and the third slide 5 all adopt cross-roller guide type precision slides to ensure stability and smoothness during the sliding process. Since it belongs to the prior art, it will not be described here. The first slide 3 is connected to the base 2 and reciprocates along the first direction. The second slide 4 is connected to the first slide 3 and reciprocates along the second direction. The third slide 5 is connected to the second slide 4 and reciprocates along the third direction, and the flip assembly is connected to the third slide 5. Through the cooperation of the first slide 3, the second slide 4 and the third slide 5, the spherical sample can be accurately positioned and moved in three-dimensional space, thereby meeting the requirements of different measurement angles and positions. The flexibility and accuracy of the measurement are improved, providing strong support for the comprehensive evaluation of spherical samples.

[0036] Reference Figures 1 to 4Furthermore, the power sources of the first slide 3, the second slide 4 and the third slide 5 can be motors, cylinders, etc. In the present embodiment, the power sources of the first slide 3, the second slide 4 and the third slide 5 are all micrometer knobs 6. By rotating these knobs, the moving distance and speed of the slides can be accurately controlled to achieve three-dimensional movement of the sample in space, thereby achieving precise adjustment of the position of the spherical sample. The precise control characteristics of the micrometer knob 6 make the movement of the slide more accurate and stable, reducing the measurement error caused by improper human operation. Since the micrometer knob 6 is a prior art, it will not be described in detail here.

[0037] Reference Figures 1 to 4 Specifically, the flip assembly includes a first rotating slide 7 and a bracket 71. The bracket 71 is a U-shaped structure, and the rotating assembly is arranged on the inner wall of the middle recess of the bracket 71. Two vertical connecting frames 51 are provided on the third slide 5. The two ends of the bracket 71 are respectively rotatably connected to the corresponding connecting frames 51, so that the rotating assembly can be set downwardly eccentrically to make enough space for measuring the spherical sample. The first rotating slide 7 is set on the connecting frame 51 to drive the bracket 71 to rotate.

[0038] Specifically, the rotating assembly includes a second rotating slide 8. The sample stage 1 is arranged on the second rotating slide 8 by means of bolt connection.

[0039] Furthermore, both the first rotary slide 7 and the second rotary slide 8 are worm-gear type cross roller bearing precision rotary slides (fine-tuning platforms). Their power sources are both graduated rotary drive knobs 9. Since this is prior art, we will not elaborate on it here.

[0040] The implementation principle of an adjustment mechanism capable of measuring spherical samples of multiple sizes in the embodiment of the present application is as follows:

[0041] Place the spherical sample on the sample stage 1, preliminarily position it with the fixed hook 11, then slide the movable hook 12 to the appropriate position and secure it with the limit bolt 124. According to the measurement requirements, adjust the first, second, and third slides 5 by rotating the micrometer knob 6 so that the spherical sample reaches the predetermined measurement position. Control the rotating assembly to drive the sample stage 1 to rotate to the required angle in the XY plane. If a flip measurement is required, operate the flip assembly to drive the entire rotating assembly and the spherical sample to flip to the predetermined angle along the Z axis. At each angle and position, use the sample measuring machine to accurately measure the spherical sample, collect data and analyze it.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
