Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a split Y-axis slide for a three-dimensional laser cutting machine and its mounting structure. Background Technology

[0002] 3D laser cutting machines are high-end equipment that integrates optics, mechanics, electronics, and pneumatics. They are considered the crown jewel of laser processing equipment and are mainly used for cutting holes and trimming edges on complex stamped parts. They are widely used in aerospace, new energy vehicles and other fields.

[0003] Please refer to Chinese utility model patent publication number CN219310399U. Existing 3D laser cutting machines, whether using a single laser head or a dual laser head, all employ an offset structure mounted on one side of the crossbeam. This not only makes the machine prone to tilting due to the off-center center of gravity, requiring frequent correction adjustments, but also easily causes torsional deformation of the crossbeam over long-term use, affecting the static and dynamic characteristics of the cutting machine. Furthermore, existing Y-axis slides all use a one-piece structure, which is not only very inconvenient for correcting assembly errors, but also difficult to adjust for subsequent equipment processing precision.

[0004] Solving these problems is now a top priority. Utility Model Content

[0005] In view of this, the present invention provides a split Y-axis slide for a three-dimensional laser cutting machine and its mounting structure.

[0006] The technical solution is as follows:

[0007] The first aspect of this application relates to a split-type Y-axis slide for a three-dimensional laser cutting machine, comprising a Y-axis slide body. The Y-axis slide body, which has a ring-shaped structure, is surrounded by two opposing slider mounting assemblies and two opposing pull-button assemblies. Each slider mounting assembly includes a beam slider mounting seat and two sleeve slider mounting seats. The beam slider mounting seat includes a vertically extending vertical mounting plate and a slider connecting plate formed by bending outwards from the bottom of the vertical mounting plate. Both slider connecting plates are provided with a Y-axis slider connecting structure. Each sleeve slider mounting base is provided with a Z-axis slider connection structure. The outer side of each sleeve slider mounting base is provided with a connecting boss that is adapted to the corresponding vertical mounting plate. Each connecting boss is adjustablely installed on the inner side of the corresponding vertical mounting plate. Each pull buckle assembly consists of at least one vertically arranged pull buckle. Both ends of each pull buckle are bent inward to form a pull buckle connecting arm. Each connecting boss has a connecting arm slot on its side wall that is adapted to the corresponding pull buckle connecting arm. Each pull buckle connecting arm is adjustablely installed in the corresponding connecting arm slot.

[0008] In some embodiments, a first bolt hole array consisting of an array of bolt holes is provided on the outer side of each connecting boss. The inner end of each bolt hole in the first bolt hole array extends to the corresponding connecting arm slot. Two second bolt hole arrays consisting of an array of bolt holes are provided on each straight mounting plate. A linear bolt hole array consisting of bolt holes evenly distributed along the length direction is provided on each pull-tab connecting arm. The diameter and spacing of each adjacent bolt hole in the first bolt hole array, each adjacent bolt hole in the second bolt hole array, and each adjacent bolt hole in the linear bolt hole array are the same. At least one bolt hole in each linear bolt hole array communicates with the bolt hole in the corresponding first bolt hole array and second bolt hole array, and is locked together by bolts.

[0009] In some embodiments, the Y-axis slider connection structure includes a Y-axis slider limiting rib integrally formed on the lower side of the slider connection plate and a third bolt hole array penetrating the slider connection plate along the thickness direction, the third bolt hole array being composed of bolt holes distributed in an array.

[0010] In some embodiments, the Z-axis slider connection structure includes a Z-axis slider limiting rib integrally formed on the side of the sleeve slider mounting base away from the slider connecting plate, and a fourth bolt hole array penetrating the sleeve slider mounting base along the thickness direction, the fourth bolt hole array being composed of bolt holes distributed in an array.

[0011] In some embodiments, the slider connecting plates extend outward from the lower edge of the corresponding vertical mounting plate and tilt downward, so that the two slider connecting plates together form an "eight" shaped structure.

[0012] In some embodiments, at least one triangular reinforcing rib is provided between the outer surface of the vertical mounting plate and the upper surface of the slider connecting plate.

[0013] The second aspect of this application relates to an installation structure for the aforementioned split Y-axis slide of a three-dimensional laser cutting machine, further comprising a Z-axis sleeve and a crossbeam. The Z-axis sleeve has a flat cylindrical portion with a cylindrical structure. The circumferential outer wall of the flat cylindrical portion is surrounded by two opposing lifting guide planes and two opposing arcuate surfaces. The lifting guide planes are both planar structures, and the arcuate surfaces are both outwardly convex arcuate structures. Both the lifting guide planes and the arcuate surfaces extend in the vertical direction.

[0014] Two vertically extending first linear guide rails are installed on each of the two lifting guide planes. A vertically extending first rack is installed on one of the lifting guide planes. Two slider mounting assemblies are correspondingly arranged on the outer side of the two lifting guide planes. Two pull buckle assemblies are correspondingly arranged on the outer side of the two arc surfaces. Four Z-axis slider connecting structures are correspondingly fixedly connected to the sliders of the four first linear guide rails. A first drive motor is installed on the crossbeam slider mounting seat near the first rack. A first drive gear that meshes with the first rack is synchronously mounted on the motor shaft of the first drive motor.

[0015] A second rack and two second linear guides are installed on the crossbeam along its length. Two Y-axis slider connection structures are fixedly connected to the sliders of the two second linear guides in a one-to-one correspondence. A second drive motor is installed on the crossbeam slider mounting base away from the first rack. A second drive gear that meshes with the second rack is synchronously mounted on the motor shaft of the second drive motor.

[0016] The above-mentioned split-type Y-axis slide and its mounting structure for 3D laser cutting machines, with two Y-axis slider connection structures, allows for a centrally mounted straddle-type connection to the crossbeam. Compared to the existing offset mounting structure of the Y-axis slide, this not only keeps the overall center of gravity in the center, making the installation of the Y-axis slide stable and reliable, eliminating the need for frequent correction adjustments, but also reducing the risk of crossbeam torsional deformation. This results in excellent static and dynamic characteristics of the 3D laser cutting machine. Furthermore, the split-type Y-axis slide facilitates easy assembly with the Z-axis sleeve and allows for adaptation to different Z-axis sleeve sizes by changing the pull tabs or adjusting the connection position of the pull tab connecting arm and the connecting arm slot. This provides good versatility. Moreover, the split-type Y-axis slide allows for easy correction of assembly errors and adjustment of machining accuracy with subsequent equipment by adjusting the connection position of the pull tab connecting arm and the connecting arm slot, as well as the connection position of the connecting boss and the vertical mounting plate.

[0023] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0024] Example 1:

[0025] like Figure 1 As shown, a split Y-axis slide for a three-dimensional laser cutting machine mainly includes a Y-axis slide body 2, which has a ring structure.

[0026] Specifically, the Y-axis slide body 2 is formed by two oppositely arranged slider mounting components and two oppositely arranged pull-button components. That is, the two slider mounting components face each other directly, the two pull-button components face each other directly, and the two slider mounting components and the two pull-button components are arranged in a rectangular shape, thus forming a ring structure together.

[0027] Please see Figures 1-4 Each slider mounting assembly includes a beam slider mounting base 2a and two sleeve slider mounting bases 2b. The beam slider mounting base 2a includes a vertically extending vertical mounting plate 2a1 and a slider connecting plate 2a2 formed by bending the bottom of the vertical mounting plate 2a1 outward. Both slider connecting plates 2a2 are provided with a Y-direction slider connecting structure 2a21. The slider connecting plate 2a2 can be set perpendicular to the vertical mounting plate 2a1 or inclined to the vertical mounting plate 2a1.

[0028] Furthermore, in this embodiment, the slider connecting plate 2a2 preferably extends outward from the lower edge of the corresponding vertical mounting plate 2a1 and tilts downward, so that the two slider connecting plates 2a2 of the two slider mounting assemblies together form an "eight"-shaped structure. Therefore, when the split Y-axis slide moves, it can apply pressure to the crossbeam 6 through the inclined surface engagement. Compared with the pressure applied to the crossbeam 6 by the structure of the slider connecting plate 2a2 perpendicular to the vertical mounting plate 2a1, the method of this embodiment can reduce the pressure on the crossbeam 6, thereby improving the structural stability of the crossbeam 6 and reducing the risk of the crossbeam 6 bending downward in the middle.

[0029] Furthermore, at least one triangular reinforcing rib 2a3 is provided between the outer surface of the vertical mounting plate 2a1 and the upper surface of the slider connecting plate 2a2, which can effectively improve the structural strength of the crossbeam slider mounting seat 2a and prevent deformation.

[0030] Each of the four sleeve slider mounting seats 2b is equipped with a Z-axis slider connecting structure 2b1. The outer side of each sleeve slider mounting seat 2b is provided with a connecting boss 2b2 that matches the corresponding vertical mounting plate 2a1. Each connecting boss 2b2 is adjustablely mounted on the inner side of the corresponding vertical mounting plate 2a1. Each pull-button assembly consists of at least one vertically arranged pull-button 2c. Both ends of each pull-button 2c are bent inwards to form a pull-button connecting arm 2c1. Each connecting boss 2b2 has a connecting arm slot 2b21 on its sidewall that matches the corresponding pull-button connecting arm 2c1. Each pull-button connecting arm 2c1 is adjustablely mounted in its corresponding connecting arm slot 2b21. Therefore, the size of the split-type Y-axis slide block is adjustable in the circumferential direction.

[0031] Please see Figure 1 and Figure 6 In this embodiment, the split Y-axis slide block, through the setting of two Y-axis slider connecting structures 2a21, can be connected to the crossbeam 6 in a central straddle-type installation method. Compared with the existing offset installation structure of the Y-axis slide block, the split Y-axis slide block of this embodiment not only places the overall center of gravity in the central position, thus making the installation of the split Y-axis slide block stable and reliable, but also eliminates the need for frequent correction and adjustment, and is less likely to cause torsional deformation of the crossbeam 6, resulting in excellent static and dynamic characteristics of the 3D laser cutting machine. At the same time, due to the split structure of the Y-axis slide block... It can be easily assembled with the Z-axis sleeve 1, and can be adapted to different sizes of Z-axis sleeve 1 by changing the pull buckle 2c of different sizes or adjusting the connection position of the pull buckle connecting arm 2c1 and the connecting arm slot 2b21. It has good versatility. Moreover, the split structure of the Y-axis slide can easily correct assembly errors and cooperate with the subsequent processing accuracy adjustment of the equipment by adjusting the connection position of the pull buckle connecting arm 2c1 and the connecting arm slot 2b21 and the connection position of the connecting boss 2b2 and the vertical mounting plate 2a1.

[0032] Please see Figures 1-5 Each outer side of the connecting boss 2b2 is provided with a first bolt hole array 2b22 consisting of an array of bolt holes. That is, the first bolt hole array 2b22 consists of multiple rows and columns of bolt holes, and the inner end of each bolt hole in the first bolt hole array 2b22 extends to the corresponding connecting arm slot 2b21.

[0033] Meanwhile, each of the straight mounting plates 2a1 has two second bolt hole arrays 2a11, consisting of multiple rows and columns of bolt holes. Each of the pull-tab connecting arms 2c1 has a linear bolt hole array 2c11 consisting of bolt holes evenly distributed along its length.

[0034] The diameter and spacing of adjacent bolt holes in the first bolt hole array 2b22, the second bolt hole array 2a11, and the linear bolt hole array 2c11 are all the same. Furthermore, at least one bolt hole in each linear bolt hole array 2c11 communicates with the bolt holes in the corresponding first bolt hole array 2b22 and second bolt hole array 2a11, and is locked together by bolts (not shown in the figure). When adjusting the size and structure of the split Y-axis slide block, simply remove the bolts, then adjust the relative positions of the sleeve slider mounting base 2b and the crossbeam slider mounting base 2a, as well as the relative positions of the pull buckle 2c and the sleeve slider mounting base 2b. Once in position, tighten the bolts. This method is simple and reliable.

[0035] Example 2:

[0036] Please see Figures 1-6 A mounting structure for a split Y-axis slide block of a three-dimensional laser cutting machine includes a Z-axis sleeve 1 and a crossbeam 6. The Z-axis sleeve 1 has a flat cylindrical portion 1a with a cylindrical structure. The circumferential outer wall of the flat cylindrical portion 1a is surrounded by two opposing lifting guide planes 1a1 and two opposing arc-shaped surfaces 1a5. The lifting guide planes 1a1 are both planar structures, and the arc-shaped surfaces 1a5 are both outwardly convex arc-shaped structures. Both the lifting guide planes 1a1 and the arc-shaped surfaces 1a5 extend in the vertical direction. Among them, the arc-shaped surface 1a5, due to its arc-shaped thin plate structure, is not only easy to cast, but also has higher structural strength compared to conventional flat plate structures.

[0037] Two vertically extending first linear guide rails 1c are installed on each of the two lifting guide planes 1a1. A vertically extending first rack 1d is installed on one of the lifting guide planes 1a1. Two slider mounting assemblies are correspondingly arranged on the outer side of the two lifting guide planes 1a1. Two pull buckle assemblies are correspondingly arranged on the outer side of the two arc surfaces 1a5. Four Z-axis slider connecting structures 2b1 are correspondingly fixedly connected to the sliders of the four first linear guide rails 1c. A first drive motor 3 is installed on the crossbeam slider mounting seat 2a near the first rack 1d. A first drive gear 4 that meshes with the first rack 1d is synchronously mounted on the motor shaft of the first drive motor 3.

[0038] Therefore, the motor shaft of the first drive motor 3 drives the first drive gear 4 to rotate forward and backward, enabling the Z-axis sleeve 1 to rise or fall along the split Y-axis slide with high control precision. Furthermore, the first drive motor 3 is preferably a servo motor, which can further improve the precision control of the lifting and lowering of the Z-axis sleeve 1.

[0039] The Y-axis slider connection structure 2a21 includes a Y-axis slider limiting rib 2a211 integrally formed on the lower side of the slider connection plate 2a2 and a third bolt hole array 2a212 penetrating the slider connection plate 2a2 along the thickness direction. The third bolt hole array 2a212 is composed of bolt holes distributed in an array. After the slider of the first linear guide rail 1c is positioned on the Y-axis slider limiting rib 2a211, it is connected to the third bolt hole array 2a212 by bolts, which is simple and reliable.

[0040] A second rack 8 and two second linear guide rails 7 are installed on the crossbeam 6 along its length. Two Y-axis slider connecting structures 2a21 are fixedly connected to the sliders of the two second linear guide rails 7 in a one-to-one correspondence. A second drive motor 9 is installed on the crossbeam slider mounting seat 2a away from the first rack 1d. A second drive gear 10 that meshes with the second rack 8 is synchronously mounted on the motor shaft of the second drive motor 9.

[0041] Therefore, the motor shaft of the second drive motor 9 drives the second drive gear 10 to rotate in both directions, enabling the split Y-axis slide to translate along the crossbeam 6 with high control precision. Furthermore, the second drive motor 9 is preferably a servo motor, which can further improve the precision control of the translation of the split Y-axis slide.

[0042] The Z-axis slider connection structure 2b1 includes a Z-axis slider limiting rib 2b11 integrally formed on the side of the sleeve slider mounting base 2b away from the slider connecting plate 2a2, and a fourth bolt hole array 2b12 penetrating the sleeve slider mounting base 2b along the thickness direction. The fourth bolt hole array 2b12 is composed of bolt holes distributed in an array. After the slider of the second linear guide rail 7 is positioned on the Z-axis slider limiting rib 2b11, it is connected to the fourth bolt hole array 2b12 by bolts, which is simple and reliable.

[0043] Furthermore, a first motor mounting base 2a4 is provided on the crossbeam slider mounting seat 2a near the first rack 1d, and the first drive motor 3 is mounted on the first motor mounting seat 2a4, ensuring the reliable installation of the first drive motor 3. A second motor mounting base 2a5 is provided on the crossbeam slider mounting seat 2a near the second rack 8, and the second drive motor 9 is mounted on the second motor mounting seat 2a5, ensuring the reliable installation of the second drive motor 9.

[0044] Please see Figure 6 In this embodiment, the middle part of the crossbeam 6 has a strip-shaped hollow part 6a extending along its length direction. The lower ends of the four sleeve slider mounting seats 2b all extend into the strip-shaped hollow part 6a. Two second linear guide rails 7 are symmetrically installed on both sides of the strip-shaped hollow part 6a, ensuring the stability and reliability of the overall structure.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
