Example one

Before introducing the method and the device for generating the personalized and customized 3D printing Luban lock, some basic knowledge possibly involved in the scheme is explained.

Luban lock: the tenon-and-mortise structure consists of a plurality of internal components which are engaged with each other in a concave-convex manner. Octagonal ball Luban lock is one kind of Luban lock, and it comprises the internals of six groups tenon fourth of the twelve earthly branches structures, and multiunit internals is 90 degrees interlocks each other in X axle, Y axle, the three direction of Z axle, and every internals is inside to be the cockscomb structure, and central bulge is positive four pyramid, and the side respectively is 45 degrees, just guarantees that 6 components can wrap up out 360 degrees spheroids. The only dismounting method of the octagonal ball Luban lock is as follows: and selecting an X-axis, a Y-axis and a Z-axis internal component to be spliced into a group to obtain two groups of structures, wherein the two groups of structures are assembled and disassembled in a cube 45-degree oblique diagonal manner.

As shown in fig. 1-3, fig. 1 is an external structural schematic diagram of a complete octagonal tumbler lock, fig. 2 is six internal components of the octagonal tumbler lock, and fig. 3 is a schematic diagram of the six internal components which are spliced into a group and then combined.

Therefore, the two internal components of the octagonal Luban lock are matched with each other, each internal component comprises a concave part and a convex part, 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 then obtains a unique Luban lock.

Specifically, as shown in fig. 4, the scheme provides a method for generating a personalized and customized 3D printing roban lock, which includes the following steps:

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

s4, the Y-axis geometry rotates 90 degrees by taking the Y axis as a rotating shaft and then rotates 90 degrees by taking the X axis as a rotating shaft to obtain a third basic geometry, the Y-axis geometry rotates 90 degrees by taking the Y axis as a rotating shaft and then rotates 90 degrees by taking the X axis as a rotating shaft to obtain a fourth basic geometry, and the third basic geometry and the fourth basic geometry are moved to obtain a fifth basic geometry which is mirror symmetric; and carrying out subtraction of Boolean operation on the fifth basic geometric body and the Y-axis geometric body to obtain an internal component of the Luban lock.

According to the method for generating the personalized 3D printing Luban lock, the internal components can be generated according to personalized customization parameters input by a user. The Luban lock of this scheme refers to octagonal ball Luban lock, and six internals are generated to this moment this scheme, and six internals assemble into a unique octagonal ball Luban lock.

It is worth mentioning that, generally speaking, six components of the octagonal ball roban lock are consistent, so the scheme only needs to use the method to generate an internal component with a specific shape. However, if the angle of rotation of the original geometry is not 45 ° or 90 °, there will be two different components out of six.

It is worth mentioning that the internal component obtained by the scheme 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 after multiple Boolean operations. In some embodiments, the method for generating the personalized and customized 3D printing roban lock provided by the present solution may be implemented by a parametric modeling technique, but may not be limited to using the parametric modeling technique, and the present solution is exemplified by the parametric modeling technique.

Description of the parametric modeling technique:

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 operated in Rhino (Rhinoco) software. GH is mainly characterized by reducing programming threshold, not needing to write codes, adopting a graphical interface, integrating each function into a graphical module, wherein 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 called as a battery for short. Each battery can connect the output end and the input end through a connecting wire according to the programmed logic relation, 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 rotation angle of the input battery in fig. 8 is 45 degrees as shown in fig. 8. At this time, if the ratio of the length, the width and the height of the cuboid with the input personalized customization parameters is 1:1:2.5 and the rotation angle is 45 degrees, the original geometric body rotates 45 degrees along the central axis in the high direction, and the obtained internal component and the Luban lock are shown in figure 9

If the original geometry is a triangular prism, the corresponding step S1 requires selecting a Domain Box battery in GH, inputting the input end B of the Domain Box battery into the XY plane of the working surface, the default origin point is (0, 0), inputting the set bottom edge, the set waist edge and the set height at the input ends X, Y, Z, respectively, inputting P1/4 at the input end a of the Rotate Axis battery next to the Domain Box battery and the other Rotate Axis battery, and inputting the XY plane at the input end P of the Rotate Axis battery next to the Domain Box battery and the other Rotate Axis battery, where the input batteries are as shown in fig. 10.

If the original geometry is a free-form tube, a tube battery is correspondingly selected in step S1, a set radius is input at an input end R of the tube battery, and a set length is input at an input end C of the tube battery, and the input battery is as shown in fig. 18. If the input customized parameters are a free-curve tube with a radius of 1 and a length of 12.13, the resulting inner member and roban lock are shown in fig. 19.

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

As shown in fig. 4 1-2, the first basic geometry designed based on the basic rectangle forms two shearing planes on the original geometry, the two shearing planes are symmetrically arranged by taking the center of the cross section of the original geometry as the center, and the two shearing planes are perpendicular to each other and form an angle of 45 degrees with the cross section of the original geometry. As shown in fig. 4 1-3, the present solution performs an intersection operation of boolean operations on the first basic geometry and the original geometry to obtain a Z-axis geometry. The structure composed of the Z-axis geometric body cutting body and the original body obtained by the scheme is that the first basic geometric body cuts two corners of the original geometric body.

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

The first base geometry has a height that lies perpendicular to the XY plane of the original geometry, and the second base geometry has a height that lies parallel to the XY plane of the original geometry.

As shown in fig. 4 1 to 4, the X-axis geometry includes an original body and a cut body which are connected, a height-direction edge line of the second basic geometry is disposed at an interface of the original body and the cut body, and the second basic geometry is disposed at a position where the cut body is disposed. In order to make the convex part of the generated internal component be a central regular rectangular pyramid, the upper and lower second basic geometric bodies of the scheme are connected.

This scheme forms four 4 continuous mutually perpendicular shear planes in the Y axle direction of X axle geometry through the setting of second basis geometry, and arrange the shear plane of the top in with the X axle direction of X axle geometry is 45 degrees angles. And after carrying out Boolean operation combination operation on the second basic body and the X-axis geometric body, carrying out Boolean operation subtraction operation on the second basic body and the X-axis geometric body to obtain a Y-axis geometric body, wherein the Y-axis geometric body is a geometric body component subjected to Boolean operation in the X-axis direction, and the middle regular rectangular pyramid is a convex part of the internal component.

If the scheme is realized by a parametric modeling technology, a Rotate Axis battery is correspondingly selected in GH in the step S3, the first basic geometric body is rotated by 90 degrees by taking an X Axis as a rotating Axis, a Move battery is selected to copy two batteries up and down along the Z Axis of the X Axis geometric body, 4 continuous and vertical shearing surfaces which are arranged along the Y Axis direction through the gravity center of the X Axis geometric body are formed, a Solid Union battery is selected to perform merging operation of Boolean operation, a Solid Difference battery is selected in GH to perform Boolean operation subtraction operation, and a three-dimensional model after Boolean operation in the 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 a length direction mirror image of the Y-axis geometry, and the third base geometry and the Y-axis geometry are arranged orthogonally. The bottom plane of the third basic geometric solid and the side plane of the Y-axis geometric solid are overlapped, the bottom plane of the fourth basic geometric solid and the side plane of the Y-axis geometric solid are overlapped, the interface surface where the third basic geometric solid and the fourth basic geometric solid are connected is overlapped with the plane where the center of the convex part of the Y-axis geometric solid is located, that is, the third basic geometric solid and the fourth basic geometric solid are in mirror symmetry with the center of the convex part of the Y-axis geometric solid.

As shown in fig. 4 1 to 6, the fifth basic geometry composed of the third basic geometry and the fourth basic geometry serves as a shear body, and the Y-axis geometry is sheared to obtain the internal member.

If the scheme is realized by a parametric modeling technology, a Rotate Axis battery is correspondingly selected in GH in step S4 to Rotate the Y-Axis geometry by 90 degrees along the Y-Axis, then Rotate by 90 degrees along the X-Axis, a Move battery is selected, the alignment entity is moved along the X-Axis to obtain a third basic geometry, similarly, the Y-Axis rotates by 90 degrees along the Y-Axis, then Rotate by-90 degrees along the X-Axis, a Move battery is selected, the alignment entity is moved along the X-Axis to obtain a fourth basic geometry, and two entities which are mirror symmetric in the X-Axis direction are formed to obtain a fifth basic geometry.

In addition, the scheme can utilize a 3D printing technology to print after the internal components are obtained through design, and the individually designed 3D printing Luban lock is obtained.

In a specific example, considering the nozzle caliber and wall thickness of 3D printing, such as 0.4mm, the internal component solid model needs to be shifted by half wall thickness in the plane, such as 0.2mm, and then the roban lock component model automatically generated by the battery pack is saved as stl file, so that the roban lock component can be printed and manufactured by a 3D printer. The roban lock member was then made with a 3D printer.
