Description

Technical Field

[0001] This invention relates to the field of solar array deployment test equipment, and more specifically, to a method for establishing a reference axis, a method for adjusting transverse and longitudinal guide rails, and a system thereof. Background Technology

[0002] During spacecraft assembly and testing, the ground deployment test of flexible solar arrays is a crucial step in verifying the reliability of solar arrays in orbit. The ground deployment test device typically consists of a large frame structure composed of multiple transverse and longitudinal guide rails, used to simulate the deployment process of solar arrays in space. The geometric accuracy of this device directly affects the alignment accuracy between the solar array and the simulation wall, as well as the authenticity of the deployment test data. Therefore, high-precision adjustment of the horizontality, straightness, parallelism, and perpendicularity of the transverse and longitudinal guide rails within the frame system is an important prerequisite for ensuring the effectiveness of the test.

[0003] Currently, the precise adjustment of large multi-track systems mainly relies on the following technical means: First, using a theodolite with an offset head to measure the straightness and levelness of a single guide rail is cumbersome due to manual point-by-point measurement. Furthermore, when there are many guide rails with complex layouts, it is difficult to establish a unified measurement benchmark, making it difficult to accurately control the relative positional relationships (such as parallelism and perpendicularity) between the rails. Second, while using a laser tracker for three-dimensional coordinate measurement offers high accuracy, the equipment is expensive, requires highly skilled operators, and suffers from low measurement efficiency and difficulty in real-time guidance and adjustment in large-scale, long-stroke field applications. Third, traditional methods such as using steel wire or levels have limited accuracy, are easily affected by the field environment, and cannot meet the requirements of modern aerospace high-precision testing.

[0004] Furthermore, most existing technologies focus on measuring the straightness or levelness of a single guide rail. For complex frame systems composed of multiple intersecting guide rails, there is a lack of a comprehensive adjustment method that can systematically take into account both the accuracy of a single rail and the relative positional relationship (parallelism, perpendicularity) between multiple rails. In particular, during the adjustment process, the various accuracy indicators are coupled with each other. If the benchmarks are not unified, it is easy to cause repeated adjustments, low efficiency, or even failure to meet the design specifications. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings mentioned in the background art and provide a method for establishing a reference axis, a method and system for adjusting horizontal and vertical guide rails, which adopts a unified reference axis and a spatial reference and has the advantages of convenient adjustment calculation, high efficiency and high adjustment accuracy.

[0006] The objective of this invention is achieved through the following technical solutions: In a first aspect, the present invention provides a method for establishing a reference axis, comprising the following steps: Select a reference guide rail; Obtain the first and second markers arranged along the length of the reference guide rail; Obtain the two sets of first perpendicular points formed by the first and second punctuation points on the ground; Obtain the first line connecting the two sets of first perpendicular points and the extension of the first line, wherein the first line and the extension intersect at the first perpendicular point of the first marker. Obtain the station located on the extension line, and center and level the theodolite erected on the station so that the telescope in the theodolite can see through all the guide rails; Move a set of reference objects that are slidably mounted on the reference rail to the first mark point, and adjust the knob of the theodolite so that the center of its crosshairs is aligned with a set of reference points on the reference objects; Slide the reference point to the second mark, and adjust the theodolite knob only for pitch to align the crosshairs with the reference point again; the telescope's line of sight is the target reference axis.

[0007] The reference axis establishment method of the present invention has at least the following beneficial effects: By using the reference guide rail and the steps described above to establish the reference axis and spatial reference, it is easy to transform all complex spatial geometric relationships into simple, repeatable, and uniformly referenced measurement standards.

[0008] Furthermore, the steps for obtaining the first connection and its extension include the following sub-steps: A laser level is set up at one of the first vertical points in one of the groups. Adjust the laser level so that the emitted beam passes through another set of first perpendicular points, so that the first connecting line and its extension line are located on the optical axis of the beam. The aforementioned first connecting line and extension line can be easily constructed and displayed using the laser level.

[0009] Secondly, the present invention provides a method for adjusting horizontal and vertical guide rails, comprising: Preparation steps: Select a set of transverse guides from all guides as the reference guides, obtain the reference axis using the method described above, and establish a spatial reference based on the reference axis. Adjustment steps: Obtain the adjustment amounts for the horizontality, straightness, parallelism, and perpendicularity of several support points of all horizontal and vertical guide rails and complete the adjustment.

[0010] In the horizontal and vertical guide rail adjustment method of the present invention, after obtaining the reference axis and establishing the spatial reference, the telescope in the theodolite and the reference axis it establishes will become the absolute standard for measuring the deviation of any point on any guide rail, and can be observed through the telescope in the theodolite, which is convenient for precise adjustment.

[0011] Furthermore, when adjusting the levelness and straightness of all guide rails, first adjust the levelness and straightness of the reference guide rail, and then adjust the straightness and levelness of the remaining horizontal and vertical guide rails. Therefore, the reference guide rail that has been adjusted can be used as an indirect spatial reference to improve the convenience of subsequent guide rail adjustments.

[0012] Furthermore, when adjusting the levelness and straightness of each set of guide rails, the height of several support points on the guide rails is adjusted to ensure that the vertical height difference between each set of support points on the guide rails and the line of sight is within the tolerance range.

[0013] For example, to ensure that the aforementioned vertical height difference is accurately reflected on the telescope's scale, the steps for adjusting the levelness and straightness of each set of guide rails are as follows: Slide the reference object onto the guide rail to be adjusted; Move the reference object to each set of support points on the guide rail, and after each movement, observe through the telescope whether the height difference between the reference point and the center of the crosshair is within the set tolerance zone. If not, adjust the current support point height until the height difference between the reference point and the center of the crosshairs falls within the tolerance zone.

[0014] Furthermore, the adjustment steps include the following sub-steps: Adjust the levelness and straightness of the reference guide rail; Adjust the levelness and straightness of the remaining horizontal guide rails; Using the reference guide rail as a reference, adjust the parallelism between all the transverse guide rails; Adjust the levelness and straightness of all longitudinal guide rails; Select a set of longitudinal guide rails as the first adjustment guide rails, and adjust the perpendicularity between the first adjustment guide rails and the reference guide rails; Using the first guide rail as a reference, adjust the parallelism between all longitudinal guide rails.

[0015] Furthermore, the perpendicularity adjustment steps between the reference guide rail and the pre-adjustment guide rail include the following sub-steps: Obtain the third and fourth markers arranged along the length of the guide rail; Obtain the two sets of second perpendicular points formed by the third and fourth punctuation points on the ground; Obtain a second line connecting the two sets of second perpendicular points, and the second line has a set of intersection points with the first line; Obtain a reference line located on the ground that passes through the intersection point, and the reference line is perpendicular to the first connecting line; Obtain the angle α between the second connecting line and the reference line; The adjustment amount of several support points located on the pre-adjustment guide rail is calculated using the formula ΔX≈D*sinα, and fine adjustments are made according to the adjustment amount. In the formula, ΔX is the adjustment amount of the support point, and D is the distance from the support point to the intersection point.

[0016] Thirdly, the present invention provides a horizontal and vertical guide rail adjustment system, the system including a theodolite, a clamp, a levelness detection fixture and a laser leveling instrument; Theodolites are used to obtain reference axes; The fixture is used to measure the parallelism between any two sets of guide rails in the same direction; The levelness testing fixture is used as a reference object. The levelness testing fixture has a scale, which is used to measure the height difference between the reference point and the center of the crosshairs. The laser level is used to obtain the first connection line, the second connection line, the reference line, and the extension line.

[0017] The horizontal and vertical guide rail adjustment system of the present invention has at least the following beneficial effects: By establishing a unified benchmark through a theodolite, and transmitting and representing the benchmark on the visible first line, second line, reference line, and extension line through a laser level, the levelness detection fixture achieves one-dimensional readings, and the clamp simplifies the parallelism detection method, making the adjustment accuracy, efficiency, and applicability of the horizontal and vertical guide rails more extensive. At the same time, the above-mentioned various types of fixtures and instruments are widely used in daily operations, which can reduce the operating threshold for operators.

[0018] Furthermore, the levelness testing fixture is also equipped with a light to illuminate the scale.

[0019] Furthermore, the levelness testing fixture is also equipped with a counterweight structure. Attached Figure Description

[0021] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0022] Example 1: Reference Figure 1 This embodiment provides a method for establishing a reference axis, including the following steps: Select a set of reference guide rails 10; Obtain the first mark 10a and the second mark 10b arranged along the length of the reference guide rail 10. Obtain two sets of first perpendicular points 10c formed on the ground by the first punctuation point 10a and the second punctuation point 10b; Obtain the first line 10d connecting the two sets of first perpendicular points 10c and the extension line 10f of the first line 10d, wherein the first line 10d and the extension line 10f intersect at the first perpendicular point 10c below the first punctuation point 10a. Obtain the station 10g located on the extension line 10f, and center and level the theodolite 3 erected on the station 10g so that the telescope in the theodolite 3 can see through all the guide rails; Move a set of reference objects that are slidably mounted on the reference guide rail 10 to the first mark 10a, and adjust the knob of the theodolite 3 so that the center of its crosshairs is aligned with a set of reference points on the reference objects; Slide the reference point to the second mark 10b, and adjust the theodolite 3 only in pitch to align the center of the crosshairs with the reference point again; the telescope's line of sight is the required target reference axis.

[0023] In the above-described method for establishing a reference axis, in order to make the line connecting the first punctuation mark 10a and the second punctuation mark 10b as close as possible to the extension direction of the reference guide rail 10, so as to reduce the amount of adjustment work during the subsequent adjustment of the reference guide rail 10, the following two points should be followed as much as possible when selecting the first punctuation mark 10a and the second punctuation mark 10b: First, the first punctuation mark 10a should be close to one end of the reference guide rail 10, and the second punctuation mark 10b should be as close as possible to the other end of the reference guide rail 10; Second, in the viewing direction perpendicular to the end face of the reference guide rail 10, the first punctuation mark 10a and the second punctuation mark 10b should be as close as possible or even overlap.

[0024] In the above method for establishing the reference axis, the two sets of first vertical points 10c can be obtained by suspending plumb lines at the first mark 10a and the two sets of second marks 10b; of course, they can also be obtained using electronic instruments such as laser plumb bobs or the curved eyepiece of a total station.

[0025] In the above-mentioned method for establishing the reference axis, the so-called "station" refers to the location where the measuring equipment (theodolite 3 in this embodiment) is set up. The position of the station 10g needs to be a certain distance from the first perpendicular point 10c under the first marker 10a, so as to ensure that the telescope in the theodolite 3 can observe all the guide rails to be measured and adjusted, that is, the telescope can see through all the guide rails.

[0026] In the above method for establishing the reference axis, the timing of installing the reference object on the reference guide rail 10 is not limited; it only needs to be done before the step of observing the reference object through the telescope.

[0027] In the above-mentioned method for establishing the reference axis, when the reference object moves to the first mark 10a, one or more of the horizontal brake knob, horizontal fine adjustment knob, telescope brake knob, and telescope fine adjustment knob of the theodolite 3 can be adjusted to align a set of reference points on the reference object with the center of the telescope crosshairs. At this time, the horizontal brake knob and horizontal fine adjustment knob of the theodolite 3 are kept stationary.

[0028] In the above-mentioned method for establishing the reference axis, when the reference object moves to the second mark 10b, the horizontal brake knob and the horizontal fine adjustment knob are not adjusted. Only the telescope fine adjustment knob or the telescope brake knob needs to be adjusted to achieve the pitch adjustment of the theodolite 3 so that the center of the crosshairs on the current telescope is aligned with the same reference point on the reference object again. At this time, the line of sight of the telescope is the required target reference axis.

[0029] It should be noted that in the theodolite adjustment steps of the above-described reference axis establishment method, the reason why the center of the crosshairs on the telescope can be aligned with the same reference point on the reference object again simply by adjusting the elevation of the telescope after the reference object has moved to the second mark 10b is due to the structure of the guide rail, that is: the reference... Figure 3The guide rails, including the reference guide rail 10, are generally supported by the bracket 7. Along the length of the guide rail, there are several support points 70 arranged at intervals for support and limitation. Therefore, with the support and limitation of several support points 70, the extension direction of each group of guide rails in the horizontal plane is linear.

[0030] When the bracket 7 is selected to fix the guide rail by hanging, the so-called support point 70 can also refer to the hanging point.

[0031] Therefore, the levelness and straightness adjustments in subsequent embodiments are actually corrections and adjustments to the vertical bending of the guide rail caused by the height difference of different support points 70 and the self-weight of the guide rail, rather than corrections and adjustments to the bending of the guide rail in the horizontal plane.

[0032] Furthermore, in the above embodiments, the steps for obtaining the first connecting line 10d and the extension line 10f employ the following sub-steps: First, a laser level 4 is set up at one of the first vertical points 10c; Then, the laser level 4 is adjusted so that its emitted beam passes through another set of first vertical points 10c. Since the laser level 4 beam can propagate a long distance, the first connecting line 10d and the extension line 10f are both located on the optical axis of the beam. Therefore, the aforementioned first connecting line 10d and extension line 10f can be easily constructed and displayed by the laser level 4.

[0033] Among them, the laser level 4 priority laser scanning instrument, compared with the ordinary laser level, uses a high-speed rotating laser head to establish a horizontal benchmark in a very large range (usually with a radius of 150 meters or more), making the first connecting line 10d and the extension line 10f clearer and more accurate.

[0034] In the reference axis establishment method of the present invention, the reference guide rail 10 and the above-mentioned steps are used to establish the reference axis, which makes it easy to transform all complex spatial geometric relationships into simple, repeatable, and uniformly referenced measurement standards.

[0035] Therefore, the reference axis established by the above-described reference axis establishment method can be extended to a spatial reference. For example, the spatial reference can be... Figure 1 The three-dimensional rectangular coordinate system O-xyz shown (which defines the x-axis in the coordinate system as parallel or collinear with the reference axis, and then determines the y-axis and z-axis in the coordinate system based on the x-axis) is used to assign coordinates and quantization parameters to various points on the reference guide rail 10.

[0036] Therefore, the reference axis establishment method in this embodiment can be applied to operation scenarios such as measurement, installation and fine adjustment of spatial physical structures such as guide rails and frames, and is not limited to the installation accuracy adjustment of guide rails.

[0037] Example 2: This embodiment applies the reference axis establishment method from Embodiment 1 to a complex spatial guide rail structure comprising several transverse guide rails 1 and several longitudinal guide rails 2, thereby adjusting the installation accuracy of the several transverse guide rails 1 and several longitudinal guide rails 2 in the complex spatial guide rail structure.

[0038] Therefore, this embodiment provides a method for adjusting horizontal and vertical guide rails, including preparation steps and adjustment steps: In the preparation step, a set of transverse guide rails 1 are selected from all guide rails as reference guide rails 10, and the reference axis is obtained by using the reference axis establishment method provided in Embodiment 1, and a spatial reference is established with the reference axis.

[0039] In the adjustment process, the coordinate measurements of each point of each guide rail are performed using the aforementioned reference axis and spatial reference. The coordinate measurements are then compared with the spatial reference to quantify the adjustment data of each guide rail. Adjustments are then made based on the aforementioned adjustment data, including adjustments to four parameters: horizontality, straightness, parallelism, and perpendicularity.

[0040] The so-called straightness and levelness refer to the degree to which several horizontal guide rails 1 and several vertical guide rails 2 maintain a horizontal and straight shape in the vertical plane, so as to avoid the guide rails from bending up and down or sagging at the ends in the vertical plane.

[0041] Parallelism refers to the degree to which several transverse guide rails 1 and several longitudinal guide rails 2 remain parallel to each other.

[0042] The term "perpendicularity" refers to the degree of perpendicularity between several longitudinal guide rails 2 and several transverse guide rails 1.

[0043] In the horizontal and vertical guide rail adjustment method of the present invention, after obtaining the reference axis and establishing the spatial reference, the telescope in the theodolite 3 and the reference axis it establishes will become the absolute standard for measuring the deviation of any point on any guide rail, and can be observed through the telescope on the theodolite 3, which is convenient for precise adjustment.

[0044] Furthermore, in this embodiment, the definitions of the transverse guide rail 1 and the longitudinal guide rail 2 differ depending on the reference frame or the spatial perspective of the measurer. That is, under different reference frames or different spatial perspectives of the measurer, the same guide rail can be identified as the transverse guide rail 1 or the longitudinal guide rail 2. Those skilled in the art can determine this according to the actual working conditions, and no limitation is made here.

[0045] In some preferred embodiments of the horizontal and vertical guide rail adjustment method, when adjusting the levelness and straightness of all guide rails, the levelness and straightness of the reference guide rail 10 are adjusted first, and then the straightness and levelness of the remaining horizontal guide rails 1 and the remaining vertical guide rails 2 are adjusted. Therefore, the reference guide rail 10 that has been adjusted can be used as an indirect spatial reference to improve the convenience of subsequent adjustment of other guide rails.

[0046] It is easy to understand that when adjusting the levelness and straightness of each set of guide rails, the height of several support points 70 on the guide rails is actually adjusted to ensure that the vertical height difference between each set of support points 70 on the guide rails and the line of sight is within the tolerance range.

[0047] For example, in order to accurately reflect the aforementioned vertical height difference on the scale of the theodolite 3 telescope, the adjustment steps for the levelness and straightness of each set of guide rails are as follows: First, slide the reference object onto the guide rail to be adjusted; Move the reference object to each set of support points 70 on the guide rail, and after each movement, observe through the telescope whether the height difference between the reference point on the reference object and the center of the crosshair is within the set tolerance zone. If so, it proves that the support height of the current support point 70 of the guide rail meets the requirements for straightness and levelness of the guide rail, and therefore there is no need to adjust the support point 70.

[0048] If not, the current support point height of 70 needs to be adjusted until the height difference between the same reference point on the reference object and the center of the crosshair falls within the tolerance zone.

[0049] In the above embodiments, the adjustment order of the horizontality, straightness, parallelism and perpendicularity of the plurality of transverse guide rails 1 and the plurality of longitudinal guide rails 2 is not limited. Based on the aforementioned reference axis and spatial reference, the art can make adaptive adjustments to the adjustment order of the horizontality, straightness, parallelism and perpendicularity of the plurality of transverse guide rails 1 and the plurality of longitudinal guide rails 2 as needed.

[0050] This embodiment provides the optimal order for adjusting the levelness, straightness, parallelism, and perpendicularity of several transverse guide rails 1 and several longitudinal guide rails 2. Specifically, the aforementioned adjustment steps include the following sub-steps: First, adjust the levelness and straightness of the reference guide rail 10; Then, adjust the levelness and straightness of the remaining horizontal guide rails 1; Then, using the reference guide rail 10 as a reference, adjust the parallelism between all the transverse guide rails 1; Then, adjust the levelness and straightness of all longitudinal guide rails 2; Then, select a set of longitudinal guide rails 2 as the first adjustment guide rail 20, and adjust the perpendicularity between the first adjustment guide rail 20 and the reference guide rail 10; Then, using the pre-adjusted guide rail 20 as a reference, adjust the parallelism between all longitudinal guide rails 2. That is, after all longitudinal guide rails 2 are parallel to the pre-adjusted guide rail 20, each set of longitudinal guide rails 2 can be made perpendicular to each set of transverse guide rails 1.

[0051] Among them, for the parallelism detection between coherent guide rails, it can be achieved by using... Figure 4 The clamp 6 includes a linear clamping rail 60 and several sliders 61 that are slidably mounted on the clamping rail 60. The sliders 61 can be tightened and fixed at any position on the clamping rail 60 by turning the screws on the sliders 61. Since each set of sliders 61 has a slot that can be engaged in the guide rail, the slots on the two sets of sliders 61 of the clamp 6 are simultaneously engaged in the adjacent guide rails in the same direction. If the clamp 6 cannot simultaneously, smoothly and stress-free clamp the two guide rails, it indicates that there is a parallelism deviation at the cross section. The support point 70 at this point needs to be finely adjusted horizontally until the clamp 6 can be perfectly engaged.

[0052] In addition, when testing the parallelism of adjacent guide rails in the same direction, at least three equally spaced sections are selected along the entire length of the guide rail, and the testing and adjustment are repeated to ensure that the parallelism of the guide rail meets the standard throughout the entire length.

[0053] Among them, reference Figure 5 The perpendicularity adjustment steps between the reference guide rail 10 and the pilot guide rail 20 include the following sub-steps: First, obtain the third mark 2a and the fourth mark 2b arranged along its own length on the pre-adjustment guide rail 20; the selection requirements of the third mark 2a and the fourth mark 2b on the pre-adjustment guide rail 20 refer to the selection requirements of the first mark 10a and the second mark 10b on the reference guide rail 10, which will not be repeated here. Then, obtain the two sets of second perpendicular points 2c formed by the third punctuation point 2a and the fourth punctuation point 2b on the ground; the method of obtaining the second perpendicular point 2c is the same as the method of obtaining the first perpendicular point 10c, and will not be repeated here. Then, obtain the second line 2d connecting the two sets of second vertical points 2c. The second line 2d can also be obtained using the laser level 4. The second line 2d and the first line 10d have a set of intersection points 2e. Then, obtain a reference line 10e located on the ground and passing through the intersection 2e. The reference line 10e is perpendicular to the first connecting line 10d. The reference line 10e can be obtained by the laser level 4. Then, obtain the angle α between the second connecting line 2d and the reference line 10e. Since the reference line 10e is theoretically perpendicular to the first connecting line 10d, the angle α between the reference line 10e and the second connecting line 2d is the rotation adjustment amount of the first adjustment guide rail 20. Then, the adjustment amount of several support points 70 located on the pre-adjustment guide rail 20 is calculated using the formula ΔX≈D*sinα, and fine adjustments are made according to the adjustment amount; In the formula, ΔX is the adjustment amount of support point 70, and D is the distance from support point 70 to intersection point 2e.

[0054] By obtaining the adjustment amount of the support points 70 at different positions on the pre-adjustment guide rail 20 and adjusting them according to the above adjustment amount, the pre-adjustment guide rail 20 and the reference guide rail 10 can be made perpendicular to each other.

[0055] When the included angle α is very small, sinα≈α. At this time, the adjustment amount of the support point 70 near the intersection point 2e can be proportionally allocated by referring to the adjustment amount of the support point 70 far from the intersection point 2e.

[0056] Finally, after completing all the above step-by-step adjustments, a system assembly review is required. Use a theodolite to randomly check the levelness and straightness of different points on each guide rail component, use a clamp to randomly check the engagement between each parallel guide rail, and use a laser level to verify the perpendicularity of the horizontal and vertical guide rails again.

[0057] Therefore, the horizontal and vertical guide rail adjustment method provided in this embodiment can be summarized as adopting a joint measurement mode of "fixed station - moving target". First, a measurement coordinate system is established with the reference guide rail 10 as the reference. The spatial angle intersection measurement is performed on the moving precision measurement target (i.e., reference object) on the reference guide rail 10 by the theodolite 3. The straightness and levelness of each guide rail are accurately calculated and adjusted. Combined with the vertical reference projected by the laser level 4 and tooling instruments such as clamps, the system completes the parallelism and perpendicularity calibration between different guide rails. This invention transforms complex multidimensional geometric relationships into high-precision angle and position measurements, realizing the systematic precision measurement and adjustment of the basic attitude of complex spatial guide rail structures.

[0058] When applied to the guide rail frame of the solar array deployment simulation test device, it can provide reliable geometric reference support for the subsequent high-precision alignment of the solar array with the simulation wall and the accurate deployment of the solar array.

[0059] Thirdly, the present invention provides a horizontal and vertical guide rail adjustment system, the system including a theodolite 3, a clamp 6, a levelness detection fixture and a laser leveling instrument.

[0060] Among them, the theodolite 3 is used to obtain the reference axis and establish a spatial reference.

[0061] The clamp 6 is used to measure the parallelism between any two sets of guide rails in the same direction.

[0062] Among them, the levelness detection fixture 5 is used as the aforementioned reference object.

[0063] Reference Figure 6In this embodiment, the levelness detection fixture 5 has a scale, which can be used to measure the height difference between the reference point and the center of the crosshair.

[0064] In some embodiments, the levelness detection fixture 5 is also equipped with a light to illuminate the scale for easy observation.

[0065] In some embodiments, the levelness detection fixture 5 is also provided with a counterweight structure.

[0066] The laser level and the aforementioned laser level 4 are of a specific type, used to facilitate the acquisition of the first connecting line 10d, the second connecting line 2d, the reference line 10e, and the extension line 10f.

[0067] In the horizontal and vertical guide rail adjustment system of the present invention, a unified benchmark is established by the theodolite 3, and the benchmark is transmitted and displayed on the visible first connecting line 10d, second connecting line 2d, reference line 10e and extension line 10f by the laser level 4. The levelness detection fixture 5 realizes one-dimensional reading, and the clamp 6 simplifies the detection method of parallelism detection. The above-mentioned fixtures and instruments work together to make the adjustment accuracy and efficiency of the horizontal and vertical guide rails higher and the applicability wider. At the same time, the above-mentioned fixtures and instruments are widely used in daily life, which can reduce the operation threshold for operators.
