Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and particularly relates to a combined double-slide three-dimensional laser cutting system. Background Art

[0002] Three-dimensional laser cutting machines are high-end equipment integrating optics, mechanics, electricity, and pneumatics, and are regarded as the pearl on the crown of laser processing equipment. They are mainly used for hole cutting and trimming of complex stamping parts, and are widely used in fields such as aerospace and new energy vehicles.

[0003] In order to improve the efficiency of laser cutting, referring to Chinese patent applications such as those with publication numbers CN116275624A and CN219310399U, the applicant of this case has designed a series of double-channel three-dimensional laser cutting machines with two laser cutting heads. However, existing double-channel three-dimensional laser cutting machines usually only have one slide, that is: existing double-channel three-dimensional laser cutting machines are single-station three-dimensional laser cutting systems, and the two laser cutting heads can only cooperate to cut and process one workpiece, with poor flexibility in use.

[0004] Therefore, a series of three-dimensional laser cutting systems with double slides (i.e., double-station three-dimensional laser cutting systems) such as those with publication number CN220698527U have emerged on the market. The two slides can not only independently perform the loading and unloading processes for two groups of small workpieces (the two groups of small workpieces can be the same workpiece or different workpieces), but also cooperate to perform the loading and unloading of large workpieces, so that the two laser cutting heads can both process two groups of small workpieces simultaneously and cooperate to process large workpieces.

[0005] However, the applicant of this case found in actual applications that there are still defects in the loading and unloading designs of the two sets of slide loading and unloading mechanisms of existing double-slide three-dimensional laser cutting systems. Especially when loading and unloading two groups of small workpieces, the loading position and unloading position of the slide are at the same position, which is not only often difficult to arrange due to problems such as narrow space, but also very prone to misplacement problems during loading and unloading.

[0006] Solving the above problems has become an urgent task. Summary of the Invention

[0007] In view of this, the present invention provides a combined double-slide three-dimensional laser cutting system.

[0008] The technical solution is as follows:

[0009] The first aspect of the present application relates to a combined double-sliding-table three-dimensional laser cutting system, which includes a bed body, a rail sliding-table conveying mechanism, and two sets of crossbeam modules. Both ends of the bed body in the length direction are provided with sliding-table inlets and outlets. The rail sliding-table conveying mechanism includes a sliding-table rail that simultaneously passes through the two sliding-table inlets and outlets, and two sliding tables that can slide along the sliding-table rail driven by a sliding-table drive assembly. The two sets of crossbeam modules are arranged parallel to each other across the top of the bed body in the width direction and can both move along the length direction of the bed body. A side inlet and outlet is provided on one side of the bed body in the width direction. Positioning fixtures that can move along the width direction of the bed body driven by a tooling translation assembly are installed on the sliding tables.

[0010] Driven by their respective sliding-table drive assemblies, the two sliding tables can either independently enter and exit from the adjacent sliding-table inlets and outlets or synchronously enter and exit from any one of the sliding-table inlets and outlets. Moreover, when any one of the sliding tables is located beside the side inlet and outlet, the positioning fixture on this sliding table can extend out of the side inlet and outlet driven by the tooling translation assembly.

[0011] With the above combined double-sliding-table three-dimensional laser cutting system, a side inlet and outlet is added on one side of the bed body in the width direction. At the same time, the positioning fixture on the sliding table can move along the width direction of the bed body driven by the tooling translation assembly, so that when the sliding table is located beside the side inlet and outlet, the positioning fixture on this sliding table can extend out of the side inlet and outlet driven by the tooling translation assembly. When the two sliding tables cooperate to load and unload large workpieces, any two of the side inlet and outlet and the two sliding-table inlets and outlets can be used as the loading position and the unloading position. When the two sliding tables independently load and unload two sets of small workpieces (the two sets of small workpieces can be the same workpieces or different workpieces), the side inlet and outlet and the corresponding one of the sliding-table inlets and outlets can be used as the loading position and the unloading position respectively. Therefore, it is not only very convenient to arrange a robotic arm or an automatic loading mechanism (including a stacking mechanism), but also can avoid the problem of misplacement during loading and unloading. At the same time, because the side inlet and outlet is very close to the processing position, the loading and unloading efficiency is improved. And because the positioning fixture increases the freedom of translation along the width direction of the bed body, the sliding table as a whole has two degrees of freedom, and then combined with the multiple degrees of freedom (usually 5 degrees of freedom) realized on the bed body and the two sets of crossbeam modules, a redundant processing mode with super multiple degrees of freedom can be achieved, which can not only perform laser cutting processing more efficiently but also more flexibly, so that it can be applied to more complex processing profiles and obtain higher processing accuracy.

[0012] In some embodiments, the positioning tooling all includes an active carriage and a driven carriage that are parallel to each other. The tooling translation assembly all includes a tooling base fixedly installed on the corresponding slide table, a fourth rack and two fourth linear guides that are all installed on the tooling base and extend along the width direction of the bed body.

[0044] The present invention is further described below in conjunction with embodiments and drawings.

[0045] Embodiment 1:

[0046] like Figure 5 - Figure 16 As shown, a beam module mainly includes a beam 6, a Y-axis slide 2, a Z-axis sleeve 1 and a laser cutting head 5.

[0047] See also Figure 5 - Figure 7 The crossbeam 6 is composed of two strip slides 6b and two end connection seats 6c. The two strip slides 6b and the two end connection seats 6c are preferably integrally formed by a casting process, and the structural strength is high. The two strip slides 6b are both columnar or strip-shaped structures, and the two strip slides 6b are parallel to each other. The two end connection seats 6c are arranged at both ends of the two strip slides 6b, that is, one of the end connection seats 6c is fixedly connected to one end of the two strip slides 6b, and the other end connection seat 6c is fixedly connected to the other end of the two strip slides 6b.

[0048] In this embodiment, the gap between the two strip slides 6b forms a Z-axis sleeve clearance groove 6a extending in the horizontal direction, and the two ends of the Z-axis sleeve clearance groove 6a are defined by the two strip slides 6b. In addition, the upper part of the strip slide 6b is provided with a Y-direction sliding component installation structure 6b1, and the end connecting seat 6c is provided with an X-direction drive device installation structure 6c1, so that the center of gravity of the Y-axis slide 2 and the Z-axis sleeve 1 is located at the center of the beam 6, which greatly improves the stability and reliability of the Y-axis slide 2 and the Z-axis sleeve 1, and does not need to be frequently corrected and debugged, and it is not easy to cause torsional deformation of the beam 6, so that the static and dynamic characteristics of the three-dimensional laser cutting machine are excellent.

[0049] Therefore, the cross beam 6 of this embodiment enables the Y-axis slide 2 to be installed on two Y-direction sliding component mounting structures 6b1, and at the same time, the Z-axis sleeve 1 can pass through the Z-axis sleeve relief groove 6a, so as to be able to cooperate with the Y-axis slide 2 to achieve a central straddle mounting method on the cross beam 6.

[0050] Furthermore, the upper parts of the two strip-shaped slides 6b have upper support surfaces 6b2 that are both inclined plane structures. The two upper support surfaces 6b2 are symmetrically inclined downward away from each other, that is: the two upper support surfaces 6b2 together form an "eight" shape structure. At the same time, the Y-direction sliding component mounting structures 6b1 each include mounting bosses 6b11 protruding from the corresponding upper support surfaces 6b2. The mounting bosses 6b11 extend along the length direction of the corresponding upper support surfaces 6b2. Support ribs 6b12 protrude from the mutually remote sides of the two mounting bosses 6b11. Second linear guides 7 extending along their length directions are installed on the mounting bosses 6b11. The slide rails of the respective second linear guides 7 are respectively supported on the corresponding support ribs 6b12. Therefore, not only is the reliable installation of the second linear guide 7 ensured, but the two second linear guides 7 also together form an "eight" shape structure.

[0051] In this embodiment, at least one upper support surface 6b2 forms a rack mounting horizontal surface 6b3 extending in the horizontal direction on the side close to the Z-axis sleeve relief groove 6a. A rack mounting pad 11 extending along the length direction of the Z-axis sleeve relief groove 6a is installed on one of the rack mounting horizontal surfaces 6b3. A rack support rib 11a protrudes from the top surface of the rack mounting pad 11 on the side away from the Z-axis sleeve relief groove 6a. A second rack 8 extending along its length direction is installed on the rack mounting pad 11. The side of the second rack 8 away from the Z-axis sleeve relief groove 6a is supported on the rack support rib 11a, ensuring the reliable installation of the second rack 8.

[0052] Furthermore, the interiors of the strip-shaped slides 6b are all hollow structures extending along their length directions to meet the requirements of lightweight design. At the same time, a number of strengthening support ribs 6b4 distributed along their length directions are provided inside the strip-shaped slides 6b, thereby ensuring the structural strength of the strip-shaped slides 6b.

[0053] Moreover, a number of weight reduction openings 6b5 distributed along their length directions are provided on the mutually close side walls of the strip-shaped slides 6b. The respective strengthening support ribs 6b4 are located at both ends of the corresponding weight reduction openings 6b5, not only meeting the requirements of lightweight design, but also facilitating the welding of the strengthening support ribs 6b4.

[0054] In this embodiment, the X-direction driving device mounting structures 6c1 are respectively motor mounting grooves formed by recessing from the top surface of the corresponding end connecting seats 6c, facilitating the installation of the motors. Meanwhile, a number of triangular reinforcing ribs 6c2 are provided on the groove walls of the two motor mounting grooves, ensuring the structural strength of the positions of the motor mounting grooves.

[0055] Furthermore, triangular reinforcing ribs 6d are provided at the four corners of the Z-axis sleeve relief groove 6a to enhance the structural strength of the connection between the strip-shaped sliding seat 6b and the end connecting seat 6c.

[0056] Please refer to Figure 5 、 Figure 8 - Figure 11 , the Z-axis sleeve 1 includes an integrally formed flat tube portion 1a and a cylindrical tube portion 1b, with high structural strength. Among them, the flat tube portion 1a is a flat tubular structure, and the flat tube portion 1a extends in the vertical direction. The cylindrical tube portion 1b is a cylindrical structure, and the cylindrical tube portion 1b also extends in the vertical direction. Meanwhile, the cylindrical tube portion 1b is located at the lower end of the flat tube portion 1a.

[0057] In this embodiment, the flat tube portion 1a and the cylindrical tube portion 1b are coaxially arranged. Most importantly, on both sides in the width direction of the flat tube portion 1a, there are lifting guide planes 1a1 extending in the vertical direction in parallel. And the distance between the two lifting guide planes 1a1 is smaller than the diameter of the cylindrical tube portion 1b. Meanwhile, the cylindrical tube portion 1b protrudes radially from the two lifting guide planes 1a1. Additionally, on the lifting guide planes 1a1, there are lifting control component mounting structures extending in the vertical direction.

[0058] The flat tube portion 1a is used to cooperate with the Y-axis sliding seat 2, that is: the flat tube portion 1a can lift along the Y-axis sliding seat 2. The cylindrical tube portion 1b is used to mount the laser cutting head 5. Specifically, the laser cutting head 5 extends downward out of the cylindrical tube portion 1b. Among them, the laser cutting head 5 adopts a traditional laser cutting head capable of emitting laser, usually having one or two or more rotational degrees of freedom, which can be selected according to actual needs.

[0059] Therefore, on the premise of meeting the wiring requirements, the flat tube portion 1a can achieve an ultra-thin design, that is: the distance between the two lifting guide planes 1a1 can be designed to be very small. Therefore, the width of the Y-axis sliding seat 2 that cooperates with it can also be very small, thereby reducing the size and weight of the Y-axis sliding seat 2, meeting the requirements of lightweight design. And because the Z-axis sleeve 1 and the Y-axis sliding seat 2 form a special-shaped shaft-hole fit through the flat tube portion 1a, there will be no relative rotation between them, so there will be no misassembly problem during assembly, and the assembly tolerance can be greatly reduced, shortening the assembly and debugging cycle; at the same time, because the widths of the flat tube portion 1a and the Y-axis sliding seat 2 are very small, the width of the Z-axis sleeve relief groove 6a of the cross beam 6 that cooperates with them can be greatly reduced, thereby effectively improving the structural strength of the cross beam 6, making it not easy to have problems of bending deformation, reducing the maintenance frequency and use cost.

[0060] On the inner wall of the flat tube portion 1a, two wire routing relief grooves 1a2 facing each other are recessed. Both of the two wire routing relief grooves 1a2 are arranged inside the corresponding lifting guide plane 1a1 along the vertical direction. Therefore, while ensuring its own structural strength, the middle part of the flat tube portion 1a can facilitate wire routing through the two wire routing relief grooves 1a2 of the expanded diameter profile.

[0061] Furthermore, the cross-section of the flat tube portion 1a is approximately rectangular. Specifically, the circumferential outer wall of the flat tube portion 1a is enclosed by two relatively arranged lifting guide planes 1a1 and two relatively arranged arc surfaces 1a5. The lifting guide planes 1a1 are both planar structures, and the arc surfaces 1a5 are both arc-shaped surfaces protruding outward. The lifting guide planes 1a1 and the arc surfaces 1a5 both extend along the vertical direction. Among them, since the arc surface 1a5 is an arc-shaped thin plate structure, it is not only easy to cast, but also has higher structural strength compared to the conventional flat plate structure.

[0062] In this embodiment, since both of the two lifting guide planes 1a1 protrude from the cylindrical tube portion 1b horizontally to both sides, the internal space of the flat tube portion 1a can be effectively increased, facilitating more wire harnesses to pass through without increasing the width of the flat tube portion 1a.

[0063] The Z-axis sleeve 1 of this embodiment is integrally formed by a casting process, with high structural strength.

[0064] Please refer to Figure 5 、 Figure 12 - Figure 16 , the Y-axis slide 2 has an annular structure. Specifically, the Y-axis slide 2 is enclosed by two relatively arranged slider mounting components and two relatively arranged buckle components, that is: the two slider mounting components face each other, the two buckle components face each other, and the two slider mounting components and the two buckle components are arranged in a rectangular pattern, thus jointly forming an annular structure.

[0065] Each slider mounting component includes a crossbeam slider mounting seat 2a and two sleeve slider mounting seats 2b. The crossbeam slider mounting seat 2a includes a vertically extending vertical mounting plate 2a1 and a slider connecting plate 2a2 bent outward from the bottom of the vertical mounting plate 2a1. The two slider connecting plates 2a2 are respectively parallel to the corresponding upper support surface 6b2, and Y-direction slider connection structures 2a21 are provided on both of the two slider connecting plates 2a2. Among them, the slider connecting plate 2a2 can be arranged perpendicular to the vertical mounting plate 2a1 or inclined to the vertical mounting plate 2a1.

[0066] Furthermore, the slider connecting plate 2a2 of this embodiment is preferably extended outward from the lower edge of the corresponding vertical mounting plate 2a1 and inclined downward, so that the two slider connecting plates 2a2 of the two slider mounting components together form an "eight" - shaped structure (adapted to the second linear guide rail 7).

[0067] Therefore, when the Y - axis slide 2 translates, it can apply pressure to the cross - beam 6 in a way of inclined - plane cooperation. Compared with the structure where the slider connecting plate 2a2 is perpendicular to the vertical mounting plate 2a1 and applies pressure to the cross - beam 6, the method of this embodiment can reduce the pressure on the cross - beam 6, so that the structural stability of the cross - beam 6 is better, and the risk of the middle part of the cross - beam 6 sagging and bending is reduced.

[0068] 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 cross - beam slider mounting seat 2a and prevent deformation.

[0069] Z - direction slider connection structures 2b1 are provided on all four sleeve slider mounting seats 2b. Connection bosses 2b2 adapted to the corresponding vertical mounting plates 2a1 are provided on the outer sides of the sleeve slider mounting seats 2b, and each connection boss 2b2 can be adjustably mounted on the inner side of the corresponding vertical mounting plate 2a1. The buckle assemblies are each composed of at least one vertically arranged buckle 2c. Both ends of each buckle 2c are bent inward to form buckle connection arms 2c1. Connection arm slots 2b21 adapted to the corresponding buckle connection arms 2c1 are provided on the side walls of each connection boss 2b2, and each buckle connection arm 2c1 can be adjustably mounted in the corresponding connection arm slot 2b21. Therefore, the size of the Y - axis slide 2 in the circumferential direction can be adjusted.

[0070] The Y - axis slide 2 of this embodiment can be connected to the cross - beam 6 in a central - mounted straddle - type installation method by providing two Y - direction slider connection structures 2a21. Compared with the existing offset - type installation structure of the Y - axis slide, the Y - axis slide 2 of this embodiment not only makes the overall center of gravity in the central position, so that the installation of the Y - axis slide 2 is stable and reliable, without the need for frequent alignment debugging and not likely to cause torsional deformation of the cross - beam 6, making the static and dynamic characteristics of the three - dimensional laser cutting machine excellent. At the same time, since the Y - axis slide adopts a split - type structure, it can be very conveniently assembled with the Z - axis sleeve 1, and can adapt to Z - axis sleeves 1 of different sizes by replacing buckles 2c of different sizes or adjusting the connection positions of the buckle connection arms 2c1 and the connection arm slots 2b21, with good versatility. Moreover, the split - type Y - axis slide can very conveniently correct the assembly error and cooperate with the processing precision debugging of the later equipment by adjusting the connection positions of the buckle connection arms 2c1 and the connection arm slots 2b21 and the connection positions of the connection bosses 2b2 and the vertical mounting plates 2a1.

[0071] On the outer sides of the connecting bosses 2b2, there is a first bolt hole array 2b22 composed of bolt holes distributed in an array, that is: the first bolt hole array 2b22 is composed of bolt holes distributed in multiple rows and multiple columns in an array, and the inner ends of the bolt holes of the first bolt hole array 2b22 all penetrate through to the corresponding connecting arm slots 2b21.

[0072] At the same time, on the straight mounting plates 2a1, there are two second bolt hole arrays 2a11 composed of bolt holes distributed in an array, that is: the second bolt hole array 2a11 is composed of bolt holes distributed in multiple rows and multiple columns in an array. On the buckle connecting arms 2c1, there is a bolt hole linear array 2c11 composed of bolt holes evenly distributed along the length direction.

[0073] The apertures and spacings of adjacent bolt holes in the first bolt hole array 2b22, adjacent bolt holes in the second bolt hole array 2a11, and adjacent bolt holes in the bolt hole linear array 2c11 are all the same, and at least one bolt hole in each bolt hole linear array 2c11 communicates with the bolt holes in the corresponding first bolt hole array 2b22 and second bolt hole array 2a11, and they are locked into one body by bolts (not shown in the figure). When it is necessary to adjust the size and structure of the Y-axis slider 2, only the bolts need to be taken out, and then the relative positions of the sleeve slider mounting seat 2b and the cross beam slider mounting seat 2a, as well as the relative position of the buckle 2c and the sleeve slider mounting seat 2b are adjusted. After reaching the position, the bolts are locked again, which is simple and reliable.

[0074] Please refer to Figure 5 , in this embodiment, two first linear guides 1c extending in the vertical direction are installed on both lifting guide planes 1a1. On one of the lifting guide planes 1a1, a first rack 1d extending in the vertical direction is installed. Two slider mounting components are correspondingly arranged on the outer sides of the two lifting guide planes 1a1, and two buckle components are correspondingly arranged on the outer sides of the two arc surfaces 1a5. Four Z-axis slider connection structures 2b1 are fixedly connected to the sliders of the four first linear guides 1c correspondingly. On the cross beam slider mounting seat 2a close to the first rack 1d, a first driving motor 3 is installed, and a first driving gear 4 meshing with the first rack 1d is synchronously rotated and sleeved on the motor shaft of the first driving motor 3.

[0075] Therefore, by driving the first driving gear 4 to rotate forward and backward through the motor shaft of the first driving motor 3, the Z-axis sleeve 1 can be lifted or lowered along the Y-axis slider, and the control precision is high. Further, the first driving motor 3 is preferably a servo motor, which can further improve the precision control of the lifting of the Z-axis sleeve 1.

[0076] Among them, the Y-direction slider connection structure 2a21 includes a Y-direction slider limiting rib 2a211 integrally formed on the lower side of the slider connection plate 2a2 and a third bolt hole array 2a212 penetrating through the slider connection plate 2a2 in 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 1c is positioned on the Y-direction slider limiting rib 2a211, it is connected to the third bolt hole array 2a212 by bolts, which is simple and reliable.

[0077] Similarly, two Y-direction slider connection structures 2a21 are fixedly connected to the sliders of two second linear guides 7 in a one-to-one correspondence. A second driving motor 9 is installed on the crossbeam slider mounting seat 2a away from the first rack 1d. A second driving gear 10 meshing with the second rack 8 is sleeved on the motor shaft of the second driving motor 9 in a synchronous rotation manner.

[0078] Therefore, by driving the second driving gear 10 to rotate forward and backward, the motor shaft of the second driving motor 9 can make the Y-axis slider translate along the crossbeam 6, with high control precision. Further, the second driving motor 9 is preferably a servo motor, which can further improve the precision control of the translation of the Y-axis slider.

[0079] Among them, the Z-direction slider connection structure 2b1 includes a Z-direction slider limiting rib 2b11 integrally formed on the side of the sleeve slider mounting seat 2b away from the slider connection plate 2a2 and a fourth bolt hole array 2b12 penetrating through the sleeve slider mounting seat 2b in 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 7 is positioned on the Z-direction slider limiting rib 2b11, it is connected to the fourth bolt hole array 2b12 by bolts, which is simple and reliable.

[0080] In this embodiment, the first rack 1d and each first linear guide 1c are respectively installed on the corresponding lifting control component installation structures. Specifically, a plurality of flat cylinder part reinforcing ribs 1a3 are convexly formed on the lifting guide plane 1a1, which improves the structural strength of the flat cylinder part 1a. At the same time, some of the flat cylinder part reinforcing ribs 1a3 extending in the vertical direction are the lifting control component installation structures. The first rack 1d and each first linear guide 1c are respectively installed on the corresponding flat cylinder part reinforcing ribs 1c extending in the vertical direction, ensuring the installation accuracy of the first rack 1d and each first linear guide 1c.

[0081] Further, a circumferential annular reinforcing flange 1a4 is formed by protruding along the circumference at the top of the flat cylinder part 1a, thereby improving the structural strength at the entrance of the flat cylinder part 1a. At the same time, the upper parts of the flat cylinder part reinforcing ribs 1a3 extending in the vertical direction all extend to the annular reinforcing flange 1a4, improving the overall structural strength of the flat cylinder part 1a. Moreover, the upper ends of the first rack 1d and each first linear guide 1c are both in contact with the annular reinforcing flange 1a4, thereby further improving the installation accuracy of the first rack 1d and each first linear guide 1c.

[0082] Further, a plurality of annular reinforcing ribs 1b1 arranged side by side along the axial direction and axial reinforcing ribs 1b2 evenly distributed circumferentially along each annular reinforcing rib 1b1 are formed by protruding on the outer peripheral surface of the cylindrical part 1b. The annular reinforcing ribs 1b1 and the axial reinforcing ribs 1b2 together form a grid-like structure, thereby effectively improving the structural strength of the cylindrical part 1b.

[0083] Further, a first motor mounting seat 2a4 is provided on the crossbeam slider mounting seat 2a close to the first rack 1d, and the first driving motor 3 is mounted on the first motor mounting seat 2a4, ensuring the reliable installation of the first driving motor 3. A second motor mounting seat 2a5 is provided on the crossbeam slider mounting seat 2a close to the second rack 8, and the second driving motor 9 is mounted on the second motor mounting seat 2a5, ensuring the reliable installation of the second driving motor 9.

[0084] Embodiment 2:

[0085] Please refer to Figure 1 - Figure 4 , a combined double-sliding-table three-dimensional laser cutting system, including a bed 12, a rail sliding table conveying mechanism 17, and two sets of crossbeam modules as described in Embodiment 1.

[0086] Please refer to Figure 3 and Figure 4, slide table inlets and outlets 12c are provided at both ends of the bed body 12 in the length direction, and a side inlet and outlet 12d is provided on one side of the bed body 12 in the width direction. Specifically, the bed body 12 includes five columns 12a and a top frame 12b mounted on the tops of the five columns 12a at the same time. Among them, the top frame 12b is a rectangular frame structure. Specifically, the top frame 12b is formed by enclosing a rectangular structure by two relatively arranged main beams 12b1 and two relatively arranged side beams 12b2. Four of the columns 12a are respectively supported at the four corners of the top frame 12b, that is: the four corners of the top frame 12b are respectively fixedly connected to the tops of the four columns 12a. The other column 12a is supported at the middle position of one of the main beams 12b1, so that slide table inlets and outlets 12c are formed under both side beams 12b2 of the bed body 12, that is: the two slide table inlets and outlets 12c are located at both ends of the bed body 12 in the length direction; at the same time, a side inlet and outlet 12d is formed under the main beam 12b1 supported by the two columns 12a of the bed body 12, that is: the side inlet and outlet 12d is located on one side of the bed body 12 in the width direction. Among them, the extending direction of the two main beams 12b1 is the length direction of the bed body 12, the extending direction of the two side beams 12b2 is the width direction of the bed body 12, and the extending direction of the column 12a is the height direction of the bed body 12.

[0087] The above design not only ensures the structural strength of the bed body, but also is easy to expand and arrange functions at the position of the side inlet and outlet 12d.

[0088] In this embodiment, each column 12a includes a column body 12a1 extending in the vertical direction, and a column top plate 12a2 and a column bottom plate 12a3 respectively fixedly installed at the top and bottom of the column body 12a1. A number of column reinforcing plates 12a4 extending in the vertical direction are installed on the circumference of the column body 12a1. The tops of the column reinforcing plates 12a4 are respectively fixedly connected to the corresponding column top plates 12a2, and the bottoms of the column reinforcing plates 12a4 are respectively fixedly connected to the corresponding column bottom plates 12a3. Therefore, the structural strength of each column 12a is greatly improved, thereby further improving the structural strength of the bed body 12.

[0089] Furthermore, in order to improve the structural strength of the bed body 12, top frame reinforcing triangular ribs 12b3 are installed at the boundaries of the top frame 12b, thereby improving the structural strength of the top frame 12b. At the same time, in order to improve the connection strength between the top frame 12b and each column 12a, top frame reinforcing triangular plates 12b4 are also provided at the connection positions between the top frame 12b and each column 12a.

[0090] In this embodiment, two mutually parallel third linear guide rails 13 are installed on the top of the bed body 12, and third racks 14 parallel to them are installed beside the two third linear guide rails 13, that is, one third linear guide rail 13 and one third rack 14 are installed on the top of the main beam 12b1 along its length direction. At the same time, third driving motors 15 are installed on the respective end connectors 6c of the two sets of cross beam modules, and third driving gears 16 meshing with the corresponding third racks 14 are synchronously sleeved on the motor shafts of the two third driving motors 15 of each set of cross beam modules.

[0091] The cross beams 6 of the two sets of cross beam modules are installed on the corresponding sliders of the two third linear guide rails 13 in parallel, and the extending directions of the two cross beams 6 are perpendicular to the extending directions of the two third linear guide rails 13. Generally, the extending direction of the third linear guide rail 13 is the X direction, the extending direction of the cross beam 6 is the Y direction, and the extending direction of the Z-axis sleeve 1 is the Z direction.

[0092] Therefore, by driving the third driving gear 16 to rotate forward and backward through the motor shaft of the third driving motor 15, the translation of the cross beam 6 can be controlled, and the control accuracy is high. Further, the third driving motor 15 is preferably a servo motor, which can further improve the precision control of the translation of the cross beam 6.

[0093] Please refer to Figure 1 and Figure 2 , the track sliding table conveying mechanism 17 includes a sliding table track 17a and two sliding tables 17b that can slide along the sliding table track 17a driven by a sliding table driving component. The sliding table track 17a extends along the length direction of the bed body 12, and the sliding table track 17a passes through the two sliding table inlets and outlets 12c at the same time. Positioning jigs 18 that can move along the width direction of the bed body 12 driven by a tooling translation component 19 are installed on the sliding tables 17b.

[0094] In this embodiment, the two sliding tables 17b can independently enter and exit from the adjacent sliding table inlets and outlets 12c driven by their respective sliding table driving components, and can also enter and exit from any one of the sliding table inlets and outlets 12c synchronously. Moreover, when any one of the sliding tables 17b is located beside the side inlet and outlet 12d, the positioning jig 18 on the sliding table 17b can extend out of the side inlet and outlet 12d driven by the tooling translation component 19.

[0095] Therefore, when the two sliding tables 17b cooperate to load and unload large workpieces, any two of the side inlet / outlet 12d and the two sliding table inlets / outlets 12c can be used as the loading position and the unloading position; when the two sliding tables 17b independently load and unload two groups of small workpieces (the two groups of small workpieces can be the same workpieces or different workpieces), the side inlet / outlet 12d and the corresponding one sliding table inlet / outlet 12c can be used as the loading position and the unloading position respectively; therefore, not only can the robotic arm or the automated loading mechanism (including the stacking mechanism) be very conveniently arranged, but also the problem of misplacing during loading and unloading can be avoided. At the same time, because the side inlet / outlet is very close to the processing position, the loading and unloading efficiency is improved; and because the positioning tooling increases the freedom of translation in the width direction of the bed, the sliding table as a whole has two degrees of freedom, and then combined with the multiple degrees of freedom (usually 5 degrees of freedom) realized on the bed and the two sets of crossbeam modules, a redundant processing mode with super multiple degrees of freedom can be realized, which can not only perform laser cutting processing more efficiently, but also perform laser cutting processing more flexibly, so that it can be applied to more complex processing profiles and obtain higher processing accuracy.

[0096] The tooling translation assembly 19 includes a tooling base 19a fixedly installed on the corresponding sliding table 17b, a fourth rack 19b installed on the tooling base 19a and extending along the width direction of the bed 12, and two fourth linear guide rails 19c. Among them, the fourth rack 19b is usually adjacent to one of the fourth linear guide rails 19c. The tooling base 19a can be an integral structure or a split structure, and can be flexibly selected according to the actual situation.

[0097] The positioning tooling 18 includes a driving carriage 18a and a driven carriage 18b that are parallel to each other. The driving carriage 18a and the driven carriage 18b are respectively fixedly installed on the sliders of the corresponding fourth linear guide rails 19c. A fourth motor 19d is installed on the driving carriage 18a, and a fourth driving gear 19e meshing with the fourth rack 19b is synchronously rotated and sleeved on the motor shaft of the fourth motor 19d. When the workpiece is fixed on the driving carriage 18a and the driven carriage 18b, the driving carriage 18a and the driven carriage 18b move synchronously.

[0098] Therefore, by driving the fourth driving gear 19e to rotate forward and backward through the motor shaft of the fourth motor 19d, the translation of the positioning tooling 18 can be controlled with high control accuracy. Further, the fourth motor 19d preferably uses a servo motor, which can further improve the precision control of the translation of the positioning tooling 18.

[0099] The active carriage 18a includes an active carriage base 18a1 fixedly mounted on the slider corresponding to the fourth linear guide 19c, and an active carriage fixed mounting plate 18a2 and an active carriage movable mounting plate 18a3 both mounted on the active carriage base 18a1. The active carriage fixed mounting plate 18a2 is fixedly mounted at one end of the active carriage base 18a1 close to the side inlet / outlet 12d. A first elongated hole 18a11 extending along the width direction of the bed 12 is provided in the middle of the active carriage base 18a1. The active carriage movable mounting plate 18a3 is slidably fitted in the first elongated hole 18a11 through at least two bolts that can be locked or unlocked. The fourth motor 19d is mounted at one end of the active carriage base 18a1 away from the side inlet / outlet 12d.

[0100] Similarly, the driven carriage 18b includes a driven carriage base 18b1 fixedly mounted on the slider corresponding to the fourth linear guide 19c, and a driven carriage fixed mounting plate 18b2 and a driven carriage movable mounting plate 18b3 both mounted on the driven carriage base 18b1. The driven carriage fixed mounting plate 18b2 is fixedly mounted at one end of the driven carriage base 18b1 close to the side inlet / outlet 12d. A second elongated hole 18b11 extending along the width direction of the bed 12 is provided in the middle of the driven carriage base 18b1. The driven carriage movable mounting plate 18b3 is slidably fitted in the second elongated hole 18b11 through at least two bolts that can be locked or unlocked.

[0101] Therefore, by adjusting the positions of the active carriage movable mounting plate 18a3 on the active carriage base 18a1 and the driven carriage movable mounting plate 18b3 on the driven carriage base 18b1, it can adapt to workpieces of different sizes, and has good versatility.

[0102] Furthermore, in the active carriage fixed mounting plate 18a2 and the driven carriage fixed mounting plate 18b2, a bolt hole array composed of bolt holes distributed in an array is provided on one of them, and a slot hole array composed of slot holes distributed in an array is provided on the other, further improving the applicability to workpieces of different sizes.

[0103] In this embodiment, the slide table drive assembly includes a fifth rack 21 and two fifth linear guides 20 mounted in parallel on the slide table track 17a, and a fifth motor 22 respectively mounted on the slide tables 17b. The two slide tables 17b are respectively fixedly mounted on the corresponding sliders of the two fifth linear guides 20. Fifth drive gears 23 meshing with the fifth rack 21 are synchronously rotatably sleeved on the motor shafts of the fifth motors 22.

[0104] Therefore, by driving the fifth drive gear 23 to rotate forward and backward, the motor shaft of the fifth motor 22 can translate the sliding table 17b with high control precision. Further, the fifth motor 22 is preferably a servo motor, which can further improve the precision control of the translation of the sliding table 17b.

Under the inspiration of the present invention, those of ordinary skill in the art can make various similar representations without violating the purpose and claims of the present invention. Such transformations all fall within the protection scope of the present invention.
