[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0029] See also Figures 3 to 5 As shown, an embodiment of the ultra-thin same-dimensional adjustment platform provided by the present invention.

[0030] The above-mentioned ultra-thin same-dimensional adjustment platform includes:

[0031] The sliding unit includes a first platform plate 11, a second platform plate 12 and a slide plate assembly, the first platform plate 11 has a first plate surface, a first slide groove (not shown in the figure) extending along the X-axis direction is provided on the first plate surface, the second platform plate 12 is provided on the first plate surface side of the first platform plate 11, the second platform plate 12 has a second plate surface, the second plate surface is opposite to the first plate surface, and a second slide groove (not shown in the figure) extending along the Y-axis direction is provided on the second plate surface, the slide plate assembly includes a first slide plate 13 and a second slide plate 14, the first slide plate 13 is embedded in the first slide groove and the two can slide relative to each other along the X-axis direction, the second slide plate 14 is embedded in the second slide groove and the two can slide relative to each other along the Y-axis direction, and the first slide plate 13 is connected and fixed to the second slide plate 14;

[0032] The adjustment unit is arranged on the X-axis side and / or the Y-axis side of the sliding unit. The adjustment unit includes a first adjustment component 21 and a second adjustment component 22. The first adjustment component 21 is connected to the first platform plate 11 and the slide assembly and drives the slide assembly to slide and adjust the position along the X-axis direction. The second adjustment component 22 is connected to the second platform plate 12 and the slide assembly and drives the second platform plate 12 to slide and adjust the position along the Y-axis direction.

[0033] The thickness directions of the first platform plate 11, the second platform plate 12, the first slide plate 13 and the second slide plate 14 are consistent. The more the first slide plate 13 is embedded in the first slide groove and the second slide plate 14 is embedded in the second slide groove, the smaller the thickness of the adjustment platform. At the same time, it is necessary to ensure that neither the first platform plate 11 nor the first slide plate 13 can contact the second platform plate 12, and neither the second platform plate 12 nor the second slide plate 14 can contact the first platform plate 11. Therefore, the first slide plate 13 slightly protrudes out of the first slide groove, and the second slide plate 14 slightly protrudes out of the second slide groove.

[0034] The first adjusting component 21 applies a force to the slide assembly to drive the slide assembly to slide and adjust its position along the X-axis direction, and the second adjusting component 22 applies a force to the second platform plate 12 to drive the second platform plate 12 to slide and adjust its position along the Y-axis direction.

[0035] By setting a first slide groove on the first platform plate 11, the first slide plate 13 is set in the first slide groove, the second slide groove is set on the second platform plate 12, and the second slide plate 14 is set in the second slide groove, the thickness rate of the adjustment platform is greater than the sum of the thicknesses of the first platform plate 11 and the second platform plate 12, thereby greatly reducing the thickness of the adjustment platform, and free adjustment in the XY direction can be achieved even when the use scene space is limited.

[0036] In this embodiment, the size of the first slide 13 along the X-axis direction is larger than the size of the second slide 14 along the X-axis direction, the size of the second slide 14 along the Y-axis direction is larger than the size of the first slide 13 along the Y-axis direction, and the first slide 13 and the second slide 14 are cross-shaped.

[0037] The dimensions of the first chute and the first slide 13 along the X-axis are their lengths, the dimensions of the first chute and the first slide 13 along the Y-axis are their widths, the dimensions of the second chute and the second slide 14 along the Y-axis are their lengths, and the dimensions of the second chute and the second slide 14 along the X-axis are their widths. The length of the first chute is greater than the width of the second chute, and the length of the second chute is greater than the width of the first chute. The length of the first slide 13 is approximately the same as the length of the first chute, and the length of the second slide 14 is approximately the same as the length of the second chute. The lengths of the first slide 13 and the second slide 14 are perpendicular, forming a cross shape after crossing. The cross-arrangement of the first slide 13 and the second slide 14 results in a longer length, a larger connection area between the first slide 13 and the first platform plate 11, and a larger connection area between the second slide 14 and the second platform plate 12, resulting in a more stable structure.

[0038] In this embodiment, the first adjustment component 21 is provided on the negative X-axis side of the first platform plate 11, and the first adjustment component 21 connects the negative X-axis end of the first platform plate 11 and the negative X-axis end of the first slide plate 13;

[0039] The second adjusting component 22 is provided on the negative X-axis side of the second platform plate 12 , and connects the negative X-axis end of the second platform plate 12 and the negative X-axis end of the first slide plate 13 .

[0040] The second platform plate 12 moves along the Y-axis direction. The first adjustment component 21 and the second adjustment component 22 are arranged on the negative side of the X-axis of the sliding unit. Therefore, the first adjustment component 21 and the second adjustment component 22 will not be interfered by the movement of the second platform plate 12 when operating.

[0041] In this embodiment, the sliding unit also includes a first elastic component 15 and a second elastic component 16. The first elastic component 15 applies a first elastic reset force toward the negative direction of the X-axis to the slide plate assembly, and the second elastic component 16 applies a second elastic reset force toward the negative direction of the Y-axis to the second platform plate.

[0042] The first adjustment component 21 drives the slide assembly to interact in the positive direction of the X-axis, and the second adjustment component 22 drives the second platform plate 12 to move in the negative direction of the Y-axis. The first elastic component 15 applies a first elastic reset force to the slide assembly in the negative direction of the X-axis, and the second elastic component 16 applies a second elastic reset force to the second platform plate 12 in the negative direction of the Y-axis, thereby eliminating travel backlash.

[0043] In this embodiment, the first adjusting component 21 and the second adjusting component 22 are both differential heads. The first adjusting component 21 is installed on the first platform plate and pushes the slide plate assembly to slide along the positive direction of the X axis. The second adjusting component 22 is installed on the slide plate assembly and pushes the second platform plate 12 to slide along the positive direction of the Y axis.

[0044] A micrometer head is a tool used for precision measurement, commonly used in industrial production and the electronics industry. It has high precision, can measure tiny changes, and is widely used in various occasions requiring high-precision measurement. There are a variety of specifications of micrometer heads: including 0-6.5mm, 0-13mm, 0-25mm and other different specifications, suitable for different measurement needs. The first adjustment component 21 and the second adjustment component 22 are both micrometer heads. The first adjustment component 21 applies a thrust toward the positive direction of the X-axis to the skateboard assembly, and the second adjustment component 22 applies a thrust toward the positive direction of the Y-axis to the second platform plate 12, which can accurately adjust the position of the skateboard assembly and the second platform plate 12.

[0046] The first elastic component 15 is disposed in the first accommodating long hole 131 of the first slide plate 13 , and the second elastic component 16 is disposed in the second accommodating long hole 141 of the second slide plate 14 , without taking up additional space, making the ultra-thin same-dimensional adjustment platform more compact.

[0047] In this embodiment, the first elastic component 15 and the second elastic component 16 are both tension springs.

[0048] The first elastic component 15 and the second elastic component 16 are tension springs. Since the initial state of the tension springs is a tightly compressed state, they occupy a small space.

[0049] In this embodiment, the adjustment unit further includes:

[0050] A first locking assembly, comprising a first connecting member 23 and a first locking screw 24. The first connecting member 23 is provided with a first adjustment slot 231 extending along the X-axis direction. One of the first platform plate 11 and the slide assembly is fixed relative to the first connecting member 23, while the other is switchably locked and slidably connected to the first connecting member 23 along the X-axis direction via the first adjustment slot 231 and the first locking screw 24.

[0051] The second locking assembly includes a second connecting member 25 and a second locking screw 26. The second connecting member 25 is provided with a second adjustment long hole 251 extending along the Y-axis direction. One of the second platform plate 12 and the slide assembly is relatively fixed to the second connecting member 25, and the other is switchably locked and slidably connected to the second connecting member 25 along the X-axis direction through the second adjustment long hole 251 and the second locking screw 26.

[0052] When adjusting the position of the slide assembly using the first adjustment component 21, the first locking screw 24 is loosened to prevent movement of the slide assembly. After adjustment in the X-axis direction is completed, the first locking screw 24 is tightened. When adjusting the position of the second platform plate 12 using the second adjustment component 22, the second locking screw 26 is loosened to prevent movement of the second platform plate 12. After adjustment in the Y-axis direction is completed, the second locking screw 26 is tightened to position the adjustment platform and reduce the elastic return force acting on the first and second adjustment components 21 and 22.

[0053] In this embodiment, the first locking screw 24 is provided on the negative X-axis side of the first platform plate 11, one end of the first connecting member 23 is fixedly connected to one end of the second slide plate 14 in the Y-axis direction, and the other end of the first connecting member 23 is switchably connected to the first platform plate 11 in a locked state and slidable manner along the X-axis direction.

[0054] The above-mentioned second locking screw 26 is arranged on the negative side of the X-axis of the above-mentioned second platform plate 12, one end of the above-mentioned second connecting member 25 is fixedly connected to one end of the above-mentioned first slide plate 13 in the X-axis direction, and the other end of the above-mentioned second connecting member 25 is switchably locked and slidably connected to the above-mentioned second platform plate 12 along the Y-axis direction.

[0055] The second platform plate 12 moves along the Y-axis direction, and the first locking screw 24 and the second locking screw 26 are arranged on the negative side of the X-axis of the sliding unit. Therefore, the first locking screw 24 and the second locking screw 26 will not be interfered with by the movement of the second platform plate 12 when tightening or loosening.

[0056] In this embodiment, the sliding unit further includes a first guide rail 17 and a second guide rail 18 . The first slide 13 is connected to the first slide groove via the first guide rail 17 , and the second slide 14 is connected to the second slide groove via the second guide rail 18 .

[0057] The accuracy grade of a guide rail refers to the positioning precision and smoothness of movement achieved during installation and operation. According to international standards, guide rail accuracy grades are primarily classified into the following categories: Standard Grade (N): Suitable for general machinery and equipment requiring less stringent requirements; High Precision Grade (H): Suitable for machinery and equipment with medium precision requirements, such as precision machine tools and measuring instruments; Ultra-High Precision Grade (P): Suitable for machinery and equipment with high precision requirements, such as CNC machine tools and precision measuring instruments; Precision Grade (SP): Suitable for equipment requiring extremely high precision, such as optical instruments and semiconductor manufacturing equipment; Ultra-Precision Grade (UP): Suitable for applications requiring the highest precision, such as nanotechnology equipment and high-precision machining centers. Different accuracy grades for primary and secondary guide rails can be selected based on specific needs.

[0058] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible.
