The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present invention.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, fig. 1 is a flowchart of a method for generating a fastener hole site. The fastener hole site generation method is used for generating an assembly hole matched with a fastener on a three-dimensional model of an insert and comprises the following steps of:
S1, acquiring a mounting surface of an insert;
s2, constructing a reference coordinate system based on the mounting surface;
s3, generating arrangement points in the range of the minimum rectangular containing box of the mounting surface according to a reference coordinate system based on design standards; design criteria include a standard distance between adjacent fasteners;
s4, generating assembly holes on the mounting surface according to the arrangement points.
In this embodiment, after the three-dimensional model of the insert is built, the mounting surface of the insert (i.e., the surface of the insert matched with the stamping die) is found out, and a reference coordinate system is built on the mounting surface, and after the reference coordinate system is built, the minimum rectangular containing box range of the mounting surface can be defined, so that the arrangement points generated in the mounting surface range are limited, and the accurate generation of the assembly holes on the mounting surface is ensured.
When the method is actually applied, the arrangement points can be automatically generated on the mounting surface of the three-dimensional model of the insert after the method is operated, then a user can select part or all of the arrangement points according to the needs and generate the assembly holes on the selected arrangement points, so that the three-dimensional model design of the insert is completed, a designer does not need to manually design and select a reference coordinate system in the whole design process, and the designer does not need to design and describe all the assembly holes one by one, so that the design efficiency is greatly improved, and the whole design period of the stamping die is shortened.
In certain embodiments, the specific steps in step S1 comprise:
S11, acquiring all characteristic surfaces of the insert;
S12, based on the assembly positions of the inserts on the stamping die, the mounting surface is identified according to the center height of each characteristic surface.
In this embodiment, the insert is a three-dimensional workpiece, and therefore includes a plurality of feature surfaces, wherein the feature surfaces matched with the mold are mounting surfaces, and for a stamping mold having only an upper mold and a lower mold and the insert mounted on the upper mold or the lower mold, whether the feature surfaces are mounting surfaces can be rapidly determined according to the center height of the feature surfaces.
Specifically, the specific steps in step S12 include:
S121, when the insert is assembled on an upper die of the stamping die, a feature surface with the highest center height is used as a mounting surface;
S122, when the insert is assembled on the lower die of the stamping die, the feature surface with the lowest center height is used as a mounting surface.
For example, based on a preset space coordinate system of the stamping die, the height (i.e., z-axis coordinate value) of each characteristic surface of the insert can be obtained, and when the insert is assembled on the upper die, the characteristic surface with the highest height (i.e., the maximum value of the z-axis coordinate) is known as the mounting surface; similarly, when the insert is assembled to the lower die, the feature surface with the lowest height (i.e., the minimum z-axis coordinate value) is known as the mounting surface.
In certain embodiments, referring to fig. 2, the specific steps in step S2 include:
s21, screening out all characteristic surfaces perpendicular to the mounting surface and taking the characteristic surfaces as target characteristic surfaces;
S22, determining a reference surface according to the distance between the center of each target characteristic surface and the center of the stamping die;
S23, taking a boundary line of the reference surface and the mounting surface, which are overlapped, as a reference line segment, and calculating a normal vector of the reference line segment on the mounting surface;
S24, taking the center of the reference line segment as the origin of the reference coordinate system, and forming the reference coordinate system by the reference line segment and the normal vector.
In the present embodiment, in practical application, for example, a target feature surface farthest from the center of the stamping die is used as a reference surface, so that a reference line segment can be obtained, and coordinate values at two ends of the reference line segment can be obtained based on a preset stamping die space coordinate system, which are respectivelyAnd/>Wherein/>Pair/>And/>The tangent vector/>, of the reference line segment can be obtained by performing differenceThe normal vector/>, based on the tangent vector of the reference line segment, of the reference line segment can be calculated:
;
Finally, the center point of the reference line segment is taken as the origin of coordinates of the reference coordinate system:
;
A reference coordinate system ozz is constructed.

s31, generating an arrangement point according to the following formula:

The dashed box range shown in fig. 2 is the minimum rectangular containing box range of the insert mounting surface, and because the formula is calculated by referring to the design standard, a plurality of arrangement points which preliminarily meet the design standard can be quickly generated in the minimum rectangular containing box range for reference by a user.
In certain embodiments, referring to fig. 4, the specific steps in step S4 include:
s41, adjusting the positions of the arrangement points, and after the adjustment is completed, generating corresponding assembly holes at the positions of part or all of the arrangement points according to the actual specification of the fastener.
In the embodiment, during practical application, the shape and structure of the insert are complex, and the situation that the positions of certain arrangement points do not meet the machining requirement possibly occurs, so that in order to ensure the flexibility of design, a user can actively select a single or a plurality of arrangement points and control the arrangement points to move towards the X-axis or Y-axis direction on a reference coordinate system; the position of the part of the arrangement points can be selected and designated to be kept still before moving, then the positions of the rest of the arrangement points are moved, after adjustment, the positions of the updated arrangement points are displayed, and the assembly holes are formed in the designated single or multiple arrangement points according to the needs of a user, and then the fasteners with corresponding specifications can be called and assembled according to the assembly holes.
