When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification.

It should be noted that: in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the method may include more or fewer steps than described in this specification. Furthermore, individual steps described in this specification, in other embodiments, may be described as being split into multiple steps; while various steps described in this specification may be combined into a single step in other embodiments.

Example 1

Before introducing the method and the device for generating the personalized custom 3D printing Luban lock, some basic knowledge possibly related to the scheme is described.

Luban lock: the mortise and tenon joint structure consists of a plurality of internal components which are meshed with each other in a concave-convex way. The eight-angle ball Luban lock is one kind of Luban lock, and it comprises six sets of internal components of tenon fourth of twelve earthly branches structure, and multiunit internal components is 90 degrees interlock each other in X axle, Y axle, Z axle three direction, and every internal component is inside to be the cockscomb structure, and the central protruding part is regular quadrangular pyramid, and the side is 45 degrees respectively, just guarantees that 6 components can wrap up 360 degrees spheroids. The only disassembly and assembly method of the octagon Luban lock is as follows: and selecting one inner member of the X axis, the Y axis and the Z axis to splice into one group to obtain two groups of structures, wherein the two groups of structures are assembled and disassembled in a cube 45-degree diagonal manner.

As shown in fig. 1-3, fig. 1 is a schematic diagram of the external structure of a complete octagonal ball-and-luban lock, fig. 2 is six internal components of the octagonal ball-and-luban lock, and fig. 3 is a schematic diagram of the six internal components assembled into a group and then recombined.

From the above, two internal components of the octagonal ball Luban lock are mutually matched, each internal component comprises a concave part and a convex part, wherein the convex part is a central regular rectangular pyramid, and the concave part is a notch obtained after multiple Boolean operations. The scheme designs unique internal components based on personalized customization parameters input by a user, and further obtains the unique Luban lock.

Specifically, as shown in fig. 4, the present solution provides a method for generating a personalized customized 3D print luban lock, including the following steps:

s2: designing a basic rectangle on an XY plane of a maximum peripheral bounding box of the original geometric body, wherein the length of the basic rectangle is not less than twice the length of the XY plane of the maximum peripheral bounding box of the original geometric body, the width of the basic rectangle is not less than twice the width of the XY plane of the maximum peripheral bounding box of the original geometric body, and at least one corner of the basic rectangle is aligned with the midpoint of one side on the XY plane of the maximum peripheral bounding box of the original geometric body; the basic rectangle rotates 45 degrees along the corners on an XY plane of a maximum peripheral bounding box of the original geometric body, and the basic rectangle is stretched along an orthogonal direction of the basic rectangle to obtain a first basic geometric body; performing an intersection operation of Boolean operation on the first basic geometry and the original geometry to obtain a Z-axis geometry;

By the personalized customization 3D printing Luban lock generation method, internal components can be generated according to personalized customization parameters input by a user. The Luban lock of this scheme refers to the eight corner balls Luban lock, and this scheme generates six internals this moment, and six internals assemble into a unique eight corner balls Luban lock.

It should be noted that, in general, the six members of the octagon ball lock are identical, so that the present solution only needs to use the above method to generate an internal member with a specific shape. However, if the rotation angle of the original geometry is not 45 ° or 90 °, there will be two different members out of six.

It is worth mentioning that the internal component that this scheme obtained includes concave part and convex part, wherein the convex part is the square pyramid of center, and the breach after the concave part is many boolean operations. In some embodiments, the method for generating the personalized custom 3D print luban lock provided by the present solution may be implemented by using a parametric modeling technique, but may not be limited to using the parametric modeling technique, and the present solution is illustrated by using the parametric modeling technique.

Description of parametric modeling techniques:

the parametric modeling technology refers to the construction of a three-dimensional model in a graphical algorithm programming mode, mainly represented by Grasshopper (GH), and operates in Rhino (Rhino) software. The GH is mainly characterized in that programming thresholds are reduced, codes do not need to be written, a graphical interface is adopted, each function is integrated into a graphical module, the left end of the module is an input end parameter of the function, the right end of the module is an output end result of the function, the middle of the module is a name or an icon of the function, and the graphical module is simply called a battery. Each battery can be connected with an output end and an input end through a connecting wire according to the programmed logic relationship, and a plurality of batteries are connected to form a battery pack, so that a computer programming program with a specific algorithm is formed. The input end parameters of the battery are modified, and the battery pack automatically generates a result according to an algorithm, so that the modeling efficiency is greatly improved. If the scheme is implemented by adopting a parameterized modeling technology, the scheme can be realized through a battery pack of GH, and the internal component of the Luban lock can be quickly obtained through parameters input to the input end of the battery.

In step S1, the user may input a customized custom parameter, where the customized custom parameter includes at least a geometric parameter of the original geometric body, and the geometric parameter is a positive number that is not 0. It is worth mentioning that the original geometry of the present solution includes, but is not limited to: cuboid, triangular prism, sphere, cylinder, cone, free curve tube, etc. The user simply selects the original geometry of the corresponding type and inputs the geometric parameters of the original geometry.

Personalized customization parameters corresponding to the original geometry input of the cuboid include, but are not limited to: the set length/set width and set width may also be input as the rotation angle of the original geometry in some embodiments, where the length of the original geometry is the length, the width is the width, and the height is the height. The present solution designs the original geometry based on the personalized customization parameters resulting in an original geometry 1-1 as shown in fig. 4.

In the example of the scheme, if the original geometric body is a cuboid, the direction in which the length of the original geometric body is located is an X axis, the direction in which the width is located is a Y axis, the direction in which the height is located is a Z axis, and the original geometric body is built in a three-dimensional coordinate system; if the original geometric body is a triangular prism, taking the bottom plane of the maximum peripheral bounding box of the triangular prism as an XY plane, defining an X axis and a Y axis, and taking the height direction of the triangular prism as a Z axis; if the original geometric body is a sphere, taking any plane passing through the center of a circle of a maximum peripheral bounding box of the sphere as an XY plane and defining an X axis and a Y axis, taking a normal line of the XY plane as a Z axis, and if the original geometric body is a cylinder, taking a bottom plane of the maximum peripheral bounding box of the cylinder as the XY plane and defining the X axis and the Y axis, and taking the height direction of the cylinder as the Z axis; if the original geometric body is a cone, taking the bottom plane of the maximum peripheral bounding box of the cone as an XY plane, defining an X axis and a Y axis, and taking the height direction of the cone as a Z axis; if the original geometric body is a free curve tube body, the free curve tube body is formed by lofting a circle along the free curve, the center of the circle is on the end point of the free curve, the plane of the circle of the maximum peripheral bounding box is taken as an X axis and a Y axis, and the normal line of the plane is taken as a Z axis.

In some embodiments, the scheme is realized by a parameterized modeling technology, and when the parameterized modeling battery pack is built, the automatic generation of the Luban lock internal components of different types of geometric bodies can be completed only by modifying the input battery of the battery pack.

If the original geometry is a cuboid, in step S1, a corresponding Domain Box battery needs to be selected from GH, the input end B of the Domain Box battery inputs the XY plane of the working surface, the default origin is (0, 0), and the input end X, Y, Z inputs the set length, the set width and the set height respectively. The input battery at this time is shown in fig. 5. If the length, width and height ratio of the cuboid of the input personalized customization parameters is 2:1:2, the resulting internals and luban lock are shown in fig. 6; if the length, width and height ratio of the cuboid of the input personalized customization parameters is 2:3:4, the resulting internals and luban lock are shown in fig. 7.

If the original geometry is cuboid and the rotation angle is set, in step S1, the corresponding input end B of the Domain Box battery needs to be selected from GH, the input end B of the Domain Box battery inputs the XY plane of the working surface, the default origin is (0, 0), the input end X, Y, Z inputs the set length, the set width and the set height, respectively, and the rotation angle is input at the input end a of the Rotate Axis battery next to the Domain Box battery. As shown in fig. 8, the input battery in this case has a rotation angle of 45 degrees in fig. 8. At this time, if the ratio of the length, width and height of the cuboid of the input personalized customization parameter is 1:1:2.5, and a rotation angle of 45 degrees, the original geometry being rotated 45 degrees about the central axis in the high direction, the resulting internals and luban lock being as shown in FIG. 9

If the original geometry is a triangle, in step S1, the corresponding input terminal B of the Domain Box needs to input the XY plane of the working surface, the default origin is (0, 0), the input terminal X, Y, Z inputs the set bottom edge, the set waist edge and the set height respectively, the input terminal a of the roller axle battery and the other roller axle battery next to the Domain Box inputs P1/4, and the input terminal P of the roller axle battery and the other roller axle battery next to the Domain Box inputs the XY plane, at this time, the input battery is shown in fig. 10. If the proportion of the triangular columns of the input personalized customization parameters is 1:1:2.5, the resulting internals and luban lock are shown in fig. 11.

If the original geometric body is a sphere, the selection in GH is needed in step S1 correspondinglyspherosomeThe radius is input at the input end R of the battery, spherocome battery, and the input battery is shown in FIG. 12. If the input personalized customization parameters are spheres, the resulting internals and the luban lock are shown in fig. 13.

If the original geometry is a cylinder, in step S1, a cylinder battery is selected correspondingly, the input end R of the cylinder battery inputs a set radius, and the input end L inputs a set height, and the input battery is shown in fig. 14. If the input personalized customization parameters are cylinders with rounded bottom radii of 2 and a height of 2.828, the resulting internals and luban lock are shown in fig. 15.

If the original geometry is a cone, in step S1, a cone battery is selected correspondingly, the input end R of the cone battery inputs a set radius, and the input end L inputs a set height, and the input battery at this time is shown in fig. 16. If the input personalized customization parameters are cones with a base radius of 2 and a height of 4, the resulting internals and luban lock are shown in fig. 17.

If the original geometry is a free curve tube, in step S1, a tube battery is selected from GH, the radius is set by the input end R of the tube battery, the length is set by the input end C, and the input battery is shown in fig. 18. If the input personalized customization parameter is a free curved tube body with a radius of 1 and a length of 12.13, the obtained internal component and the luban lock are shown in fig. 19.

In step S2, the present solution designs a base rectangle on the XY plane of the maximum peripheral bounding box of the original geometry, the length and width of the base rectangle being at least 2 times the length and width of the XY plane of the maximum peripheral bounding box of the original geometry, which is advantageous in that the first base geometry constructed in this way can be used to completely cut the corners of the original geometry. In the scheme, one corner of the basic rectangle is aligned with one corner of the long and wide plane of the original geometric body, and the length of the rectangular side of the basic rectangle and the length of the long and wide side of the original geometric body are 45 degrees.

As shown in fig. 4 1-2, the first basic geometric body based on the basic rectangular design forms two shearing surfaces on the original geometric body, the two shearing surfaces are symmetrically arranged by taking the center of the cross section of the original geometric body as the center, and the two shearing surfaces are mutually perpendicular and form 45 degrees with the cross section of the original geometric body. 1-3 of FIG. 4, the present solution performs a Boolean intersection operation on the first base geometry and the original geometry to obtain a Z-axis geometry. The Z-axis geometrical body obtained by the scheme cuts the structure formed by the body and the original body, namely, the first basic geometrical body cuts two corners of the original geometrical body.

If the scheme is realized by a parametric modeling technology, in the step S2, a rectangular battery is required to be selected in GH correspondingly, an XY working plane which is the same as that of an original geometric body is input by an input end B, the original point is (0, 0), the side length of the input end X, Y of the basic Rectangle is at least 2 times of the length and the width of the original geometric body on the XY plane, then a Move and Rotate Axis battery is selected, the basic Rectangle is rotated 45 degrees and aligned with the original geometric body along an X Axis, then an Extrude battery is selected, and the basic Rectangle is pulled up along a Z Axis to obtain a first basic geometric body; and selecting Solid Intersection batteries in GH to perform the intersection operation of Boolean operation, and calculating the Z-axis geometry.

In step S3, the first base geometry is rotated 90 degrees with the X-axis as the rotation axis, to obtain a second base geometry. The first base geometry has a height that is disposed perpendicular to the XY plane of the original geometry and the second base geometry has a height that is disposed parallel to the XY plane of the original geometry.

As shown in fig. 4 1-4, the X-axis geometry includes an original body and a cut body that are joined, the height-wise edges of the second base geometry being positioned at the interface of the original body and the cut body, and the second base geometry being positioned at the location of the cut body. In order to make the convex part of the generated internal member be a central regular rectangular pyramid, the upper and lower two second base geometric bodies of the present solution meet.

The setting of this scheme through the second basic geometry forms four 4 continuous mutually perpendicular shear planes in the Y axis direction of X axis geometry, and places in the shear plane of top with the X axis direction of X axis geometry is 45 degrees angles. And carrying out the Boolean operation combining operation on the second basic body and the X-axis geometric body, and then carrying out the Boolean operation subtracting operation to obtain a Y-axis geometric body, wherein the Y-axis geometric body is a geometric body component subjected to the Boolean operation in the X-axis direction, and the middle regular square pyramid is a convex part of the internal component.

If the scheme is realized by a parametric modeling technology, a rotary Axis battery is selected in GH in the step S3 correspondingly, a first basic geometric body is rotated 90 degrees by taking an X Axis as a rotation Axis, a Move battery is selected to copy two of the first basic geometric body up and down along a Z Axis of the X Axis geometric body, continuous 4 mutually perpendicular shearing planes which are arranged along a Y Axis direction through the gravity center of the X Axis geometric body are formed, a Solid Union battery is selected, a merging operation of Boolean operation is performed, a Solid Difference battery is selected in GH, a subtraction operation of Boolean operation is performed, and a three-dimensional model after Boolean operation in a Y Axis direction is calculated to obtain the Y Axis geometric body.

In step S4, the third base geometry and the fourth base geometry are arranged in mirror image in a length direction of the Y-axis geometry, and the third base geometry and the Y-axis geometry are arranged orthogonally. The bottom plane of the third base geometry and the side plane of the Y-axis geometry overlap, the bottom plane of the fourth base geometry and the side plane of the Y-axis geometry overlap, and the plane where the interface between the third base geometry and the fourth base geometry and the center of the convex portion of the Y-axis geometry lie overlap, that is, the third base geometry and the fourth base geometry are mirror-symmetrical about the center of the convex portion of the Y-axis geometry.

As shown in fig. 4 1-6, a fifth base geometry consisting of a third base geometry and a fourth base geometry acts as a shear body, shearing the Y-axis geometry to obtain an internal member.

If the scheme is implemented by the parametric modeling technology, in the step S4, a rotation Axis is selected in GH to Rotate the Y-Axis geometric body by 90 degrees, then by 90 degrees, a Move cell is selected, the alignment entity is moved in X Axis to obtain a third basic geometric body, the same rotation Axis is rotated by 90 degrees, then by-90 degrees, the Move cell is selected, the alignment entity is moved in X Axis to obtain a fourth basic geometric body, and two entities which are mirror symmetrical in X Axis direction are formed to obtain a fifth basic geometric body. And selecting a Solid Difference battery in GH, performing Boolean subtraction operation, and calculating a three-dimensional model subjected to Boolean operation in the X-axis direction to obtain an internal component of the Luban lock.

The structure of the parameterized battery pack designed according to the scheme is shown in fig. 20, and the parameterized battery pack designed according to the scheme can quickly generate the internal components of the luban lock.

It is worth mentioning that the personalized customization 3D printing luban lock generating method according to the present solution can generate different internal components for different personalized customization parameters. In addition, after the internal components are designed, the scheme can be printed by utilizing a 3D printing technology, and the 3D printing Luban lock with personalized design is obtained.

In a specific example, considering the 3D printed nozzle bore and wall thickness, e.g., 0.4mm, it is necessary to offset the in-plane of the internal component solid model by half the wall thickness, e.g., 0.2mm, and then save the battery pack automatically generated lubanlock component model as a stl file to facilitate printing of the 3D printer to make the lubanlock component. The luban lock component was then fabricated using a 3D printer. The size was printed using a conventional FDM fused pile 3D printer, such as a polar 603S printer: 180x180x280mm, nozzle 0.4mm, print layer thickness: 0.1mm-0.3mm, positioning accuracy: the XY axis: 0.01mm, Z axis: 0.0025mm, printing material: ABS plastic, PLA material, consumable diameter: 1.75mm. 3D printers with higher printing precision, such as industrial-grade high-precision photo-curing 3D printer LG-345, can also be selected for printing the size: 527x295x550mm, cure wavelength: 405nm, print layer thickness: 0.01mm/0.02mm/0.05mm, printing material: photosensitive resin.

The scheme carries out design examples aiming at different personalized customization parameters.

As shown in fig. 21, fig. 21 shows the logic concept of the design of the scheme, firstly, the scheme firstly constructs a parameterized modeling battery pack based on the geometric parameters of the original geometric body, then modifies the geometric parameters of the original geometric body, at the moment, the originally designed parameterized battery pack automatically generates a unique personalized customized luban lock internal component, and then the internal component of the luban lock is printed by using a 3D printing technology.
