Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0042] Reference Figure 1 According to the first aspect of the present application, the horizontal adjustment device includes an adjustment assembly 100 and a level meter 300. The adjustment assembly 100 includes a base 110 and an adjustment member 120. The adjustment member 120 is provided with at least three. The upper end of the adjustment member 120 is used to support the workpiece 200. The adjustment member 120 is connected to the base 110. The position of the adjustment member 120 relative to the base 110 in the up-down direction can be adjusted to adjust the level of the processing surface 210 of the workpiece 200. The level meter 300 is used to measure the level of the processing surface 210.

[0043] According to the horizontal adjustment device of the embodiment of the present application, there are at least the following beneficial effects: after the workpiece 200 is placed on the adjustment member 120, the horizontality of the processing surface 210 is measured by the spirit level 300. If the horizontality is not within the error range, the horizontality of the processing surface 210 can be adjusted by adjusting the position of the adjustment member 120 relative to the base 110 in the up and down directions; through multiple measurements and adjustments, the error of the horizontality of the processing surface 210 can be reduced so that the horizontality of the processing surface 210 is within the required error range.

[0044] Specifically, the reason why at least three adjusting members 120 need to be provided is because of the principle that three points determine a surface. The number of the adjusting members 120 can be three, four, five or other numbers.

[0045] Reference Figure 2 In some embodiments of the present application, the adjustment component 100 also includes a base 140, which is supported on the base 110. The number of the base 140 and the adjustment member 120 is the same. The base 140 and the adjustment member 120 are threadedly connected one by one, and the angle between the extension direction of the thread of the adjustment member 120 and the vertical direction is less than 90 degrees.

[0046] After the base 140 and the adjusting member 120 are threadedly matched, the position of the adjusting member 120 along the up and down directions can be adjusted by simply rotating the adjusting member 120 relative to the base 140 , which has a simple structure and is easy to use.

[0047] It should be noted that the angle between the extension direction of the thread of the adjusting member 120 and the vertical direction is less than 90 degrees, in order to ensure that the adjusting member 120 can move in the up-down direction instead of the horizontal direction after the adjusting member 120 rotates relative to the base 140. Specifically, the angle between the extension direction of the thread of the adjusting member 120 and the vertical direction can be 10 degrees, 5 degrees or other angles, preferably 0 degrees.

[0048] In another embodiment, a blind hole may be provided in the base 140, and the adjusting member 120 is inserted in the blind hole, and the adjusting member 120 is in clearance with the blind hole (refer to the connection structure between the first connecting member 430 and the support 420 below). The set screw is threadedly matched with the base 140, and the set screw fixes the adjusting member 120 to the base 140. Therefore, when the position of the adjusting member 120 in the up-down direction needs to be adjusted, the set screw is loosened to allow the adjusting member 120 to move in the up-down direction in the blind hole. After the adjusting member 120 moves to the target position, the set screw is tightened to achieve the position adjustment of the adjusting member 120 in the up-down direction.

[0049] Reference Figure 2 In an improved solution of the above embodiment, the distance between at least two bases 140 can be adjusted.

[0050] The position distribution of the adjusting member 120 determines the minimum size and maximum size of the workpiece 200 that the adjusting member 120 can support. When the size of the workpiece 200 to be supported changes, the adjusting member 120 can adapt to the new workpiece 200 by adjusting the distance between at least two bases 140, thereby stably supporting the new workpiece 200.

[0051] That is, by making the distance between at least two bases 140 adjustable, it is helpful to expand the application scope of the level adjustment device, and the compatibility of the level adjustment device is stronger.

[0052] Specifically, the distance between two, three, four, all or another number of bases 140 can be adjusted.

[0053] Specifically, the base 140 can be directly placed on the base 110, and the distance between at least two bases 140 can be adjusted by translating one or more bases 140. In addition, in order to increase the stability of the base 140 placed on the base 110, a magnet can be added to the base 140, and the base 110 is made of a magnetic material, so that the friction between the base 140 and the base 110 is greater, and the base 140 is not easy to shake or move.

[0054] Reference Figure 2 and Figure 3 In an improved scheme of the above embodiment, the adjustment assembly 100 also includes a locking nut 130, the number of the locking nuts 130 is not less than the number of the adjustment members 120, each adjustment member 120 is threadedly matched with at least one locking nut 130, and the locking nut 130 is used to resist the base 140.

[0055] By providing the locking nut 130 , the threaded fit between the adjusting member 120 and the base 140 can be prevented from loosening, and the adjusting member 120 is not easy to loosen.

[0056] Specifically, each adjusting member 120 may be threadedly matched with one, two, three or other number of locking nuts 130 .

[0057] It should be noted that the locking nut 130 is used to abut the base 140 . The locking nut 130 can directly contact and abut the base 140 , or the locking nut 130 can indirectly abut the base 140 by contacting and abutting another locking nut 130 .

[0058] Reference Figure 3 In an improved solution of the above embodiment, the adjusting member 120 is provided with at least one pair of clamping surfaces 121, and the clamping surfaces 121 are used for being clamped by the installation tool.

[0059] By providing at least one pair of clamping surfaces 121 , the adjusting member 120 can be conveniently clamped by an installation tool, the installation tool is not easy to slip, the installation tool can smoothly rotate the adjusting member 120 , and the upper and lower position adjustment of the adjusting member 120 is more convenient.

[0060] Specifically, the number of the clamping surfaces 121 may be one pair, two pairs, three pairs or other numbers.

[0061] It should be noted that installation tools generally refer to tools such as wrenches or pliers.

[0062] In an improved solution of the above embodiment, the surface of the adjusting member 120 is provided with anti-slip grooves.

[0063] The provision of the anti-skid pattern is also helpful for manually rotating the adjusting member 120 , so that the adjusting member 120 is not prone to slipping during the rotation process, and the upper and lower position adjustment of the adjusting member 120 is smoother.

[0064] Reference Figure 2 and Figure 3 In an improved solution of the above embodiment, a spherical surface 122 is provided at the upper end of the adjusting member 120 , and the spherical surface 122 is used to contact with the workpiece 200 .

[0065] If the upper end of the adjusting member 120 is in surface contact with the workpiece 200, the surface located after the adjusting member 120 moves up and down is not unique and is relatively random, and the positioning is relatively unstable, which is not conducive to quickly adjusting the level of the processing surface 210 of the workpiece 200. However, the spherical surface 122 is in point contact with the workpiece 200, and each adjusting member 120 provides a positioning point, and the surface located is relatively unique, which is conducive to quickly adjusting the level of the processing surface 210 of the workpiece 200.

[0066] In some embodiments of the present application, the level 300 includes one of a bubble level, an electronic digital level, a laser level, and a magnetic level.

[0067] Bubble levels, electronic digital levels, laser levels and magnetic levels are all easy to obtain and have low costs, which helps to reduce the equipment cost of the level adjustment device.

[0068] Reference Figure 2 In some embodiments of the present application, the base 110 includes a marble platform.

[0069] The density of marble is relatively high. Even with a relatively small volume, the base 110 made of marble still has a relatively large weight. The base 110 is not easy to shake, and the support provided by the base 110 is more stable.

[0070] In another embodiment, the base 110 may also be made of stainless steel.

[0071] According to the second aspect of the present application, the flatness detection device includes a horizontal adjustment device, a mounting frame 400, and a micrometer 500. The mounting frame 400 includes a support 420 and a first connecting member 430. One end of the support 420 is rotatably connected to the base 110, and the support 420 can rotate around a vertical axis relative to the base 110. The first connecting member 430 is connected to the support 420, and the position of the first connecting member 430 relative to the support 420 in the up-down direction can be adjusted.

[0072] The micrometer 500 is mounted on the first connecting member 430 . The micrometer 500 includes a probe 510 . The probe 510 is used to contact the processing surface 210 .

[0073] The flatness detection device according to the embodiment of the present application has at least the following beneficial effects: after the position of the first connecting member 430 relative to the support 420 along the up and down directions, the probe 510 of the micrometer 500 can contact the processing surface 210 of the workpiece 200, and the support 420 rotates around the vertical axis relative to the base 110, then the micrometer 500 can measure the data of multiple positions of the processing surface 210 of the workpiece 200, and then obtain the flatness data; by using the above-mentioned level adjustment device, the error of the levelness of the processing surface 210 can be reduced, which is conducive to reducing the influence of the error of the levelness of the processing surface 210 on the detection result of the flatness of the processing surface 210, and the reliability of the detection result of the flatness detection device is higher.

[0074] Specifically, one end of the support 420 can be rotatably connected to the base 110 via a bearing.

[0075] Specifically, the support 420 may be provided with an adjustment hole 421, and the lower end of the first connecting member 430 is inserted into the adjustment hole 421, and the first connecting member 430 is clearance-matched with the adjustment hole 421. The locking screw 410 is threadedly matched with the support 420, and the locking screw 410 fixes the first connecting member 430 to the support 420. When it is necessary to adjust the position of the first connecting member 430 relative to the support 420 in the up-down direction, the locking screw is loosened to allow the first connecting member 430 to move in the up-down direction in the adjustment hole 421. After the first connecting member 430 moves to the target position, the locking screw is tightened, thereby realizing the position adjustment of the first connecting member 430 in the up-down direction.

[0076] In addition, the position of the first connecting member 430 relative to the support 420 along the up-down direction can be adjusted by a gear rack mechanism or a screw nut mechanism.

[0077] Reference Figure 4In an improved scheme of the above embodiment, the mounting frame 400 also includes a second connecting member 440, which is connected to the first connecting member 430, and the position of the second connecting member 440 relative to the first connecting member 430 along the horizontal direction can be adjusted, and the micrometer 500 is installed on the second connecting member 440.

[0078] By making the position of the second connecting member 440 relative to the first connecting member 430 in the horizontal direction adjustable, the micrometer 500 can measure data of more positions of the machining surface 210 of the workpiece 200, and the measurement result of the flatness detection device is more accurate.

[0079] Specifically, the second connecting member 440 may be slidably connected to the first connecting member 430 , so as to achieve horizontal position adjustment of the second connecting member 440 relative to the first connecting member 430 .

[0080] Furthermore, the second connecting member 440 is slidably connected to the first connecting member 430, the second connecting member 440 is rotatably connected to the gear, a rack is fixed to the first connecting member 430, the length direction of the rack is arranged in the horizontal direction, and the gear is meshed with the rack. Therefore, by rotating the gear, the position of the second connecting member 440 relative to the first connecting member 430 in the horizontal direction can be more accurately adjusted.

[0081] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
