[0002] A jig is a workbench for assembling and welding curved sections, three-dimensional sections with curved surfaces, and overall sections. Its curved working surface conforms to the outer shape of the section and the overall section. During the manufacturing process of a curved section, the jig is the base surface for supporting the curved outer plate and is also the key to curved line manufacturing. In the traditional method, it is necessary to position the height of the jig while ensuring the jig spacing, which requires high precision for the workshop floor jacks and jig spacing. Due to the transformation of the workshop floor jacks and the subsidence of the terrain in some factory areas, the jig spacing deviation is relatively large. When manufacturing a curved line jig, it is necessary to adjust the spacing of each jig one by one, which takes a long time, resulting in low jig manufacturing efficiency, and there are also large cumulative errors in jig manufacturing.

[0030] To enable those skilled in the art to better understand the solution of the present invention, the following will clearly and completely describe the technical solution in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0031] Figure 1 FIG. is a flowchart of a method for adjusting a curved surface line type jig provided in an embodiment of the present invention. This embodiment is applicable to the situation of adjusting a curved surface line type jig. This method can be executed by a curved surface line type jig adjustment system, which can be implemented in the form of hardware and / or software, and the curved surface line type jig adjustment system can be configured in an electronic device. As Figure 1 shown, the method for adjusting the curved surface line type jig includes:

[0032] S101. Collect the three-dimensional coordinate data of four reference points set on the cross ground line to obtain reference point data. All four reference points are located outside the jig area.

[0033] The cross ground line of a ship jig refers to the reference line used for positioning and ensuring the correctness of the shape during the construction of a hull section. The cross ground is two intersecting and perpendicular straight lines. Generally speaking, one of the straight lines is the middle rib line, and the other straight line passes through the midpoint of the middle rib line.

[0034] All four reference points are located outside the jig area, which means that in the horizontal direction, among them, the X value of the first reference point is less than the minimum value of the X value of the jig area, the X value of the second reference point is greater than the maximum value of the X value of the jig area, the Y value of the first reference point is less than the minimum value of the Y value of the jig area, and the Y value of the second reference point is greater than the maximum value of the Y value of the jig area.

[0035] When collecting the three-dimensional coordinate data of the target object in the present invention, a total station can be used for collection.

[0036] S102. Collect the three-dimensional coordinate data of each jig column in the jig to obtain jig data.

[0037] When collecting the three-dimensional coordinate data of the jig and the reference points, both are based on the jig coordinate system, that is, the reference point data and the jig data are both coordinate data in the jig coordinate system.

[0038] S103. Taking the reference point data as the import reference, establish a three-dimensional model of the jig in the model software according to the standard three-dimensional coordinate data of the jig.

[0039] Specifically, it includes: importing the reference point data into the model software to obtain the fitted reference points; establishing a three-dimensional model of the jig in the model software according to the standard three-dimensional coordinate data of the jig; translating the three-dimensional model so that the cross ground line of the three-dimensional model is translated to cover the position of the fitted reference points, and the orientation of the cross ground line in the three-dimensional model is consistent with the orientation of the actual cross ground line corresponding to the fitted reference points.

[0040] That is, based on the four reference points, the position of the standard physical model of the jig in the jig coordinate system is positioned. The height of each point in the three-dimensional model is the reference for calculating the height deviation of the jig columns at the same position. Therefore, the orientation of the cross ground line in the three-dimensional model is consistent with the orientation of the actual cross ground line corresponding to the fitted reference points to avoid incorrect matching of the jig column data caused by incorrect placement direction of the three-dimensional model.

[0041] Optionally, the standard three-dimensional coordinate data of the jig is the coordinate data in the hull coordinate system, and the reference point data is the coordinate data in the jig coordinate system. Establishing a three-dimensional model of the jig in the model software according to the standard three-dimensional coordinate data of the jig includes: converting the standard three-dimensional coordinate data of the jig from the hull coordinate system to the jig coordinate system; establishing a three-dimensional model of the jig in the model software according to the converted standard three-dimensional coordinate data of the jig.

[0042] It should be noted that due to the large hull line of the curved surface section, the curved surface jig is usually rotated longitudinally and horizontally to the same angle in the design. The original data for sectional modeling is sectional coordinate data, and for the convenience of on-site construction, the sectional coordinate data is converted into the jig coordinate system.

[0043] S104. Import the jig data into the model software to obtain multiple measured jig column points.

[0044] Since both the jig data and the reference point data are the coordinate data in the jig coordinate system, no coordinate conversion is required when importing the jig data into the model software.

[0045] S105. For each measured jig column point, calculate the height deviation data between the measured height and the standard height corresponding to the measured jig column point. The measured height is obtained from the jig data, and the standard height is obtained from the standard three-dimensional coordinate data.

[0046] It can be known that a three-dimensional model in the jig coordinate system has been constructed in the model software, and this three-dimensional model can represent the standard height of the jig columns at each position (including the measured jig column points). The actual height (i.e., the measured height) of the jig columns at each measured jig column point can also be obtained from the measured jig column points. Therefore, the height deviation data between the measured height and the standard height corresponding to the measured jig column points can be directly calculated by comparison.

[0047] S106. Adjust the jig according to the height deviation data of the actual measured points of each column.

[0048] After the height deviation data, the jig can be adjusted according to the height deviation data of the actual measured points of each column, so that the height of each column at each position in the jig conforms to the standard, without adjusting the column spacing, and can also avoid the influence of uneven ground, construction accuracy deviation of the distance between the forklifts, the gap between the sleeve and the column core, and the collision during the process of the section being removed from the jig on the manufacturing accuracy of the jig.

[0049] To clearly illustrate the reason why the column spacing does not need to be adjusted in this solution, first combine Figure 2 with the following examples for illustration. Figure 2 It is a schematic diagram of column height adjustment when the column spacing changes. As shown in Figure (a) in Figure 2 , assume that A and B are two adjacent columns, L is the curved surface line type of the jig, the standard distance between them is 1m, the height of column B is h1, and due to the construction accuracy deviation of the distance between the forklifts, the actual distance between them is 1.1m. Without changing the column spacing, in order to keep the curved surface line type formed by the columns unchanged, the height relationship between column A and column B needs to change. As shown in Figure 2 (b) figure, the height of column B is adjusted to h2, so that the curved surface line type L of the jig can be kept unchanged without adjusting the column spacing.

[0050] The embodiment of the present invention provides a method for adjusting a curved surface line type jig. Collect the three-dimensional coordinate data of four reference points set on the cross ground line to obtain reference point data, and all four reference points are located outside the jig area; collect the three-dimensional coordinate data of each column in the jig to obtain jig data; take the reference point data as the import reference, and establish a three-dimensional model of the jig in the model software according to the standard three-dimensional coordinate data of the jig; import the jig data into the model software to obtain multiple actual measured points of the columns; for each actual measured point of the column, calculate the height deviation data between the measured height corresponding to the actual measured point of the column and the standard height, the measured height is obtained according to the jig data, and the standard height is obtained according to the standard three-dimensional coordinate data; adjust the jig according to the height deviation data of each actual measured point of the column. The reference points on the cross ground line of the jig are a reference point. By setting the reference points outside the jig area to be measured, the influence of factors such as the local terrain and column spacing within the jig area on the measurement can be reduced, thereby improving the accuracy and reliability of the measurement, and further improving the manufacturing accuracy of the jig; in addition, by comparing the actually measured column height with the standard height in the standard three-dimensional coordinate data in the model software, the height deviation of each column can be obtained quickly and intuitively, and then the height adjustment information of the jig can be provided for the staff quickly and effectively, and the column spacing does not need to be adjusted, improving the manufacturing efficiency of the jig.

[0051] In an alternative embodiment, the four reference points are respectively a first reference point, a second reference point, a third reference point, and a fourth reference point. The first reference point and the second reference point are respectively located at the left and right ends of the center point of the cross-shaped ground line, and the third reference point and the fourth reference point are respectively located at the upper and lower ends of the center point of the cross-shaped ground line. Before collecting the three-dimensional coordinate data of each column in the jig to obtain jig data, it further includes:

[0052] Taking the line connecting the first reference point and the second reference point as the first connection line; taking the line connecting the third reference point and the fourth reference point as the second connection line; calculating the included angle between the first connection line and the second connection line; determining whether the absolute value of the difference between the included angle and 90° exceeds a small angle threshold; if so, performing the step of collecting the three-dimensional coordinate data of each column in the jig to obtain jig data; if not, returning to perform the step of collecting the three-dimensional coordinate data of the four reference points set on the cross-shaped ground line to obtain reference point data. That is, measuring whether the four reference points conform to the perpendicular characteristic of the cross-shaped ground line, so that the positions of the four reference points are accurate, to ensure that the four reference points can be used as the data import reference in the subsequent steps. Among them, the preset angle threshold can be 0.5°.

[0053] In an alternative embodiment, after calculating the height deviation data of the measured height and the standard height corresponding to the measured position of each column, it further includes:

[0054] Determining whether all the height deviation data are positive or all negative; if so, translating the measured position of the column in the height direction based on all the height deviation data to eliminate the state where all the height deviation data are positive or all negative, and returning to perform the step of calculating the height deviation data of the measured height and the standard height corresponding to the measured position of each column.

[0055] When there are height deviation data that are all positive or all negative, uniformly translating the measured positions of the columns can reduce the number and amplitude of column adjustments, and can also ensure that the jig surface line type remains unchanged.

[0056] Translating the measured position of the column in the height direction based on all the height deviation data to eliminate the state where all the height deviation data are positive or all negative includes: calculating the average value of all the height deviation data to obtain the translation height; translating the measured position of the column in the height direction based on the translation height to eliminate the state where all the height deviation data are positive or all negative.

[0057] In another example, the mode of the height deviation data can also be counted as the translation height, and the unified height translation can be directly performed according to this mode. Then, the height deviation of the tire column whose height deviation data is this mode becomes 0, that is, no height adjustment is required, saving the workload and time of tire column height adjustment and improving the production efficiency of the tire rack.

[0058] In an alternative embodiment, the tire rack is adjusted according to the height deviation data of each actually measured point position of the tire column, including: for each actually measured point position of the tire column, determining whether the corresponding height deviation data exceeds a preset deviation range; if so, marking the actually measured point position of the tire column and annotating the corresponding height deviation data to provide information on tire column height adjustment for the staff.

[0059] The embodiments of the present invention have the following advantages compared with the prior art:

[0060] 1. The cumulative error caused by the tire rack spacing is reduced, the curved surface line type is accurately analyzed, and the correct production of the tire rack line type is ensured;

[0061] 2. The operation amount and time for adjusting the tire rack spacing are reduced, and the production efficiency is improved.
