Description

Technical Field

[0002] In automotive welding design systems, reference structures are distributed throughout the vehicle body. To demonstrate the position of these reference structures within the overall structure, three-dimensional cross-sectional views are typically used. While the position of each reference structure and its relationship to the vehicle body can be seen by changing the model's perspective in a 3D model, this cannot be documented. To create a more intuitive document showing the position of each reference structure within the vehicle body, a two-dimensional cross-sectional view with the optimal perspective needs to be generated for each reference structure. Currently, the generation of these cross-sectional views relies on manual labor.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0016] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0017] The following is combined Figures 1 to 9 Embodiments of the present invention will be described.

[0018] A method for generating cross-sectional views of the reference structure of a welding system, including: S100: Obtain the reference structure in the 3D model of the welding system; scan the 3D model of the welding system to capture components that conform to the reference structure characteristics, and realize the batch extraction of all reference structures.

[0019] S200, Analyze the acquired reference structure to obtain the structural information of the reference structure; S300: Based on the structural information, perform axis type determination on the baseline structure to obtain the determination result; read the generated structural information package, extract the generation category identifier, if it is an axis type, obtain the determination result of generating an axis type structure, if it is a non-axis type, generate the determination result of a non-axis type structure.

[0020] S400: Obtain the positional relationship between the reference structure and the preset reference plane to obtain positional information; associate the positional information with the reference structure to provide conditions for determining the direction of the subsequent cross-sectional plane.

[0021] S500, based on the judgment result and position information, determine the corresponding cross-sectional plane; S600: Based on the determined cross-sectional plane, generate a cross-sectional view of the reference structure; convert the optimized cross-sectional profile into a two-dimensional graphic and generate a cross-sectional view according to a preset format.

[0022] Therefore, by taking the three-dimensional model of the welding system as input, analyzing the geometric features and spatial position of the reference structure, matching different types of cross-sectional plane calculation rules according to the structural category, and finally outputting a two-dimensional cross-sectional diagram that meets the requirements, the traditional repetitive manual operation is replaced, greatly improving work efficiency.

[0023] Furthermore, the cross-sectional views of all reference structures are output in batches for easy reference and use later.

[0024] In some embodiments, step S200 involves analyzing the acquired reference structure to obtain its structural information, specifically including: S210, Analyze the acquired reference structure to obtain the geometric features of the reference structure; Analyze each reference structure to extract core feature parameters, including the outline shape, key dimensions, and surface features of the structure, and determine the core features of its forming method, such as whether there is a rotational symmetry axis, whether it is a regular stretched profile, etc.

[0025] S220, based on the geometric characteristics of the reference structure, determine the generation category of the reference structure; based on the geometric characteristics, determine whether it is formed by rotation about an axis. For example, by verifying whether the cross-section of the structure is a concentric circle and whether the longitudinal profile is symmetrical along a certain axis, and combining with the geometric definition of a rotating body, determine whether its forming method is rotational forming. If yes, determine the generation category as shaft type: when the structure meets the rotational forming characteristics, automatically mark its category as shaft type reference structure and record the initial orientation information of the rotation axis. If no, determine the generation category as non-shaft type: when the structure does not meet the rotational forming characteristics, determine that it is stretch forming or other non-rotational forming method, and mark the category as non-shaft type reference structure.

[0026] Therefore, in some embodiments, step S220, based on the geometric features of the reference structure, determines the generation category of the reference structure, specifically including: S221, Based on the geometric features of the reference structure, determine whether the geometric features of the reference structure are formed by rotation around an axis; for example, compare the extracted geometric features with the rotational forming feature model to analyze whether there is a fixed rotation axis and a geometric shape that is symmetrical about the axis.

[0027] S222, if so, then determine its generation category as shaft type; when the rotational forming feature is satisfied, automatically mark the generation category of the reference structure as shaft type.

[0028] S223, if not, then its generation category is determined to be non-axial. When the rotational forming feature is not satisfied, the system automatically marks the generation category of the reference structure as non-axial.

[0029] S230, based on the generation category of the baseline structure, obtains the structural information of the baseline structure. The generation category and geometric feature data are integrated to form a standardized structural information package. For example, the shaft-type structural information package includes shaft type identifier, rotation axis features, and key dimensions; the non-shaft-type structural information package includes non-shaft type identifier, tension direction features, and key dimensions.

[0030] In some embodiments, the preset reference plane is the base plate plane in the welding system; step S400, obtaining the positional relationship between the reference structure and the preset reference plane to obtain positional information, specifically includes: S410, establish a local coordinate system for the reference structure. Using the functional core point of the reference structure as the origin, for example, for shaft-type structures, the origin is the midpoint of the rotation axis or the center of the end face; for non-shaft-type structures, the origin is the center of the reference surface in contact with the Base plate. Based on the geometric features and assembly posture of the structure, define the X, Y, and Z axes of the local coordinate system to ensure that the coordinate axis directions accurately reflect the spatial posture of the structure. For example, the Z-axis of a shaft-type structure coincides with the rotation axis, and a certain coordinate axis of a non-shaft-type structure is consistent with the stretching direction.

[0031] S420: Extract the origin position and the direction of each coordinate axis from the local coordinate system information; parse and extract the three-dimensional coordinate data of the origin and the direction parameters of the X, Y, and Z axes from the established local coordinate system, and form the basic position data from the extracted parameters.

[0032] S430: Obtain the normal direction of the Base board plane; identify and obtain the Base board components of the welding system, extract the planar features of the Base board to obtain the normal direction vector, which serves as a reference standard for positional comparison.

[0033] S440: Compare the directions of each coordinate axis with the normal direction to obtain their positional relationship. For example, calculate the angle between the X, Y, and Z axis direction vectors of the local coordinate system and the normal direction vector of the base plate, and determine whether the angle is 0° or 180°. Record the parallelism determination result of each coordinate axis with the normal direction to clarify which coordinate axis is consistent with or parallel to the normal direction of the base plate.

[0034] S450, positional information is obtained based on positional relationships. Parallelism determination results are integrated to generate positional information, explicitly marking coordinate axes parallel to the normal direction of the Base plate.

[0035] In some embodiments, step S500 determines the corresponding cross-sectional plane based on the judgment result and position information, specifically including: shaft-type structures entering the shaft-type cross-sectional plane calculation process, and non-shaft-type structures entering the non-shaft-type cross-sectional plane calculation process.

[0036] Specifically, S510, determines whether the determination result is a shaft-type structure; S520, if so, then the corresponding cross-sectional plane is determined based on the position information and the preset axis type determination rules; S530, if not, then determine the corresponding cross-sectional plane based on the position information and the preset non-axis type determination rules.

[0037] First, based on the position information, a first direction is determined, defined as the direction parallel to the normal direction of the base plate, ensuring that the H-direction of the cross-sectional plane is perpendicular to the base plate. Next, a second direction is determined by extracting the rotation axis direction vector of the shaft-like structure and calculating its projection direction on the base plate plane, defining this as the second direction. Finally, the cross-sectional plane is generated, using the origin of the local coordinate system as its origin. Combining the first and second directions, the cross-sectional plane is constructed, ensuring that the plane simultaneously passes through the rotation axis and the Z-axis of the base plate, and satisfies the directional requirements of both the first and second directions.

[0038] In some embodiments, the local coordinate system includes an X-axis, a Y-axis, and a Z-axis; in S530, the corresponding cross-sectional plane is determined based on the position information and a preset non-axis type determination rule, specifically including: S531, based on position information, takes the direction perpendicular to the Base board plane as the first direction; S532, obtain the coordinate axes in the local coordinate system that are parallel to the normal direction of the Base plate plane; S533, analyze the parallel coordinate axes to determine the second direction; S534, if the parallel coordinate axis is the Z-axis, then the second direction is determined to be the Y-axis parallel to the local coordinate system; S535, if the parallel coordinate axis is the Y-axis, then the second direction is determined to be the Z-axis parallel to the local coordinate system; S536, If the parallel coordinate axis is the X-axis, then the second direction is determined to be the Y-axis parallel to the local coordinate system; S537, Generate the cross-sectional plane according to the determined first and second directions.

[0039] Similarly, first, the first direction is determined. Consistent with the axis structure, the direction perpendicular to the Base plate plane is defined as the first direction based on the position information. Then, the parallel coordinate axes are analyzed: coordinate axes parallel to the Base plate normal direction are extracted from the position information. Next, the second direction is determined. If the parallel coordinate axis is the Z-axis, the second direction is defined as parallel to the Y-axis of the local coordinate system; if the parallel coordinate axis is the Y-axis, the second direction is defined as parallel to the Z-axis of the local coordinate system; if the parallel coordinate axis is the X-axis, the second direction is defined as parallel to the Y-axis of the local coordinate system. Finally, the cross-sectional plane is generated: using the origin of the local coordinate system as the origin of the cross-sectional plane, and combining the first direction and the determined second direction, the cross-sectional plane is constructed, ensuring that the plane is perpendicular to the base plate and that its normal is parallel to the corresponding axis of the local coordinate system.
