Figure 2 This is a bottom schematic diagram of a flatness adjustment device provided according to an embodiment of the present invention, with reference to Figure 1 and Figure 2 , the flatness adjustment device includes:

[0040] The base, the connecting plate 1, the four wedge-shaped units 2, the wedge-shaped block fixing plate 3 and the adjusting device 4 are arranged on the first surface of the base;

[0041] Each wedge unit 2 includes a first wedge block 21, a second wedge block 22 and a third wedge block 23;

[0042] The wedge block fixing plate 3 is fixed to the base; two first wedge blocks 21 are arranged on the first surface of the wedge block fixing plate 3, and the other two first wedge blocks 21 are arranged on the second surface of the wedge block fixing plate 3; wherein the first surface of the wedge block fixing plate 3 and the second surface of the wedge block fixing plate 3 are arranged opposite to each other, and the first surface of the wedge block fixing plate 3 and the second surface of the wedge block fixing plate 3 are perpendicular to the first surface of the base;

[0043] In each wedge unit 2, the second wedge block 22 is arranged on a side of the first wedge block 21 away from the wedge block fixing plate 3, and the third wedge block 23 is arranged on a side of the second wedge block 22 away from the wedge block fixing plate 3, and the first side surface of the second wedge block 22 is arranged in contact with the first side surface of the first wedge block 21, and the second side surface of the second wedge block 22 is arranged in contact with the first side surface of the third wedge block 23; the connecting plate 1 is arranged on a side of the wedge unit 2 and the wedge block fixing plate 3 away from the base, and the connecting plate 1 is connected to the four second wedge blocks 22;

[0044] The adjusting device 4 is arranged in contact with the third wedge block 23, and the adjusting device 4 is used to apply a force to the third wedge block 23 along a first direction so that the second wedge block 22 moves along a second direction to adjust the flatness of the connecting plate 1; wherein the first direction is the direction from the third wedge block 23 to the first wedge block 21, and the second direction is perpendicular to the first surface of the base.

[0045] Specifically, when it is necessary to adjust the flatness of a workpiece to be inspected, the workpiece to be inspected can be fixed on the connecting plate 1, and then the adjusting device 4 is adjusted to apply a force to the third wedge block 23 to move the second wedge block 22 along the second direction to adjust the flatness of the connecting plate 1. For example, if one side of the connecting plate 1 connected to a certain wedge unit 2 is too low, the adjusting device 4 corresponding to the wedge unit 2 can be adjusted so that the adjusting device 4 squeezes the third wedge block 23 in the wedge unit 2 to move the second wedge block 22 along the second direction away from the base to raise the side of the connecting plate 1 connected to the wedge unit 2, thereby achieving the effect of adjusting the flatness of the connecting plate 1. The number of adjusting devices 4 can be one, two, three or four, and the embodiment of the utility model is not limited to this. For example, Figure 1A schematic diagram of four adjustment devices 4 is shown. The two first wedge blocks 21 on the second surface and the two first wedge blocks 21 on the first surface can be symmetrically arranged relative to the wedge block fixing plate 3, or the two first wedge blocks 21 on the second surface and the two first wedge blocks 21 on the first surface can be symmetrically arranged relative to the wedge block fixing plate 3.

[0046] The flatness adjustment device designed in the embodiment of the present invention is configured by setting two first wedge blocks 21 on the first surface of the wedge block fixing plate 3, and the other two first wedge blocks 21 are set on the second surface of the wedge block fixing plate 3, the second wedge block 22 is set on the side of the first wedge block 21 away from the wedge block fixing plate 3, and the third wedge block 23 is set on the side of the second wedge block 22 away from the wedge block fixing plate 3, and the first side surface of the second wedge block 22 is in contact with the first side surface of the first wedge block 21, and the second side surface of the second wedge block 22 is in contact with the first side surface of the third wedge block 23; the connecting plate 1 is set on the side of the wedge unit 2 and the wedge block fixing plate 3 away from the base, and the connecting plate 1 is connected to the four second wedge blocks 22, and the adjusting device 4 is in contact with the third wedge block 23, and the adjusting device 4 is used to apply a force to the third wedge block 23 along the first direction to make the second wedge block 22 move along the second direction to adjust the flatness of the connecting plate 1, thereby achieving the effect of adjusting the flatness of the workpiece to be inspected on the connecting plate 1.

[0047] For further reference, Figure 1 and Figure 2 , the adjusting device 4 includes: a fixing frame 41 and a pressure structure 42;

[0048] The pressure structure 42 includes a threaded pressure member 421 and a nut 422 ; the threaded pressure member 421 includes a threaded portion 4211 and a pressure portion 4212 ;

[0049] The fixing frame 41 includes a horizontal portion 411 and a vertical portion 412; the vertical portion 412 is arranged on a side of the horizontal portion 411 away from the base and fixed to an edge of the horizontal portion 411 close to the third wedge block 23, and the horizontal portion 411 is fixed to the base; a threaded hole is provided on the vertical portion 412, and a threaded portion 4211 passes through the vertical portion 412 through the threaded hole; a pressure portion 4212 is connected to the threaded portion 4211 and is arranged between the threaded portion 4211 and the third wedge block 23, and the pressure portion 4212 is arranged in contact with the third wedge block 23; a nut 422 is provided on the threaded portion 4211, and the nut 422 is arranged on a side of the vertical portion 412 away from the third wedge block 23;

[0050] When the nut 422 is rotated, the pressure portion 4212 applies a force to the third wedge block 23 along the first direction, so that the second wedge block 22 moves along the second direction to adjust the flatness of the connecting plate 1 .

[0051] The horizontal portion 411 can be fixed to the base by screws 43 .

[0052] Specifically, when it is necessary to adjust the flatness of a workpiece to be inspected, the workpiece to be inspected can be fixed on the connecting plate 1, and then the nut 422 can be rotated so that the pressure-applying portion 4212 applies a force to the third wedge block 23 along the first direction, so that the second wedge block 22 moves along the second direction to adjust the flatness of the connecting plate 1. For example, if one side of the connecting plate 1 connected to a certain wedge unit 2 is too low, the adjustment device 4 corresponding to the wedge unit 2 can be adjusted, and the nut 422 in the adjustment device 4 can be rotated so that the pressure-applying portion 4212 squeezes the third wedge block 23 in the wedge unit 2, so that the second wedge block 22 moves along the second direction away from the base to lift one side of the connecting plate 1 connected to the wedge unit 2, thereby achieving the effect of adjusting the flatness of the connecting plate 1.

[0053] For further reference, Figure 2 Four first through holes 31 are provided on the wedge block fixing plate 3, and the first connecting screws pass through the first through holes 31 to connect with the base.

[0054] Specifically, a first connecting screw is provided to pass through the first through hole 31 and connect with the base, so that the wedge-shaped fixing plate 3 is more firmly fixed to the base, thereby making the first wedge block 21 more firmly fixed, avoiding the phenomenon of misalignment of the first wedge block 21 due to excessive pressure applied by the adjustment device 4 during the process of adjusting the flatness of the connecting plate 1, thereby improving the adjustment effect of the flatness of the connecting plate 1.

[0055] For further reference, Figure 1 Four second through holes 11 are provided on the connecting plate 1, the geometric center of the second wedge block 22 is on the axis of the second through hole 11, and the second connecting screw passes through the second through hole 11 and is connected to the second wedge block 22; wherein, the second connecting screw is a screw with a spring washer.

[0056] Specifically, the geometric center of the second wedge block 22 is positioned on the axis of the second through hole 11. This allows the second wedge block 22 to move smoothly in the second direction when the adjustment device 4 is adjusted, preventing tilting. Furthermore, the second connecting screw is passed through the second through hole 11 to connect the second wedge block 22. Because the second connecting screw is a screw with a spring washer, there is a certain degree of elasticity in the connection between the second wedge block 22 and the connecting plate 1. This prevents deformation of the connecting plate 1 during fine-tuning of the flatness of the connecting plate 1 using the adjustment device 4.

[0057] Furthermore, the angle between the first side surface of the first wedge block and the bottom surface of the first wedge block close to the base is an acute angle, and the angle between the first side surface of the third wedge block and the bottom surface of the third wedge block close to the base is an acute angle.

[0058] Specifically, the angle between the first side surface of the first wedge block and the bottom surface of the first wedge block close to the base is set to be an acute angle, and the angle between the first side surface of the third wedge block and the bottom surface of the third wedge block close to the base is set to be an acute angle. When the adjusting device applies a force to the third wedge block along the first direction, the second wedge block can move smoothly along the second direction, thereby adjusting the flatness of the connecting plate.

[0059] For further reference, Figure 2 The two first wedge blocks 21 on the second surface and the two first wedge blocks 21 on the first surface are symmetrically arranged relative to the wedge block fixing plate 3.

[0060] Specifically, the two first wedge blocks 21 on the second surface and the two first wedge blocks 21 on the first surface are symmetrically arranged relative to the wedge block fixing plate 3, which makes it more convenient and simple to adjust the flatness of the connecting plate 1.

[0061] Furthermore, the first wedge-shaped block, the second wedge-shaped block and the third wedge-shaped block are all marble wedge-shaped blocks;

[0062] The connecting plate is a marble connecting plate;

[0063] The wedge block fixing plate is a marble wedge block fixing plate.

[0064] Specifically, due to marble's low coefficient of thermal expansion and contraction, using marble as a material effectively reduces deformation caused by temperature changes compared to other materials, thereby effectively improving the flatness adjustment effect of the workpiece to be inspected on the connecting plate 1. Furthermore, marble has excellent stability and is not easily affected by environmental factors, allowing the flatness adjustment device of the present invention to maintain a good adjustment effect in various environments. Furthermore, using marble as a material reduces the probability of failure of the flatness adjustment device of the present invention, thereby reducing the maintenance and replacement costs of the flatness adjustment device.
