Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and particularly to a two-station three-dimensional laser cutting system with a waste cleaning function. Background Art

[0002] Please refer to the Chinese utility model patent with the publication number CN219310399U. For existing three-dimensional laser cutting machines, whether they use a single laser cutting head or a double laser cutting head, the Y-axis slide is installed on one side of the crossbeam in an offset structure. This not only makes the whole prone to skew due to the offset of the center of gravity, so frequent alignment debugging is required, but also easily causes the crossbeam to twist and deform during long-term use, affecting the static and dynamic characteristics of the cutting machine.

[0003] Moreover, the waste generated by the existing three-dimensional laser cutting machines (the three-dimensional laser cutting machine is mainly used for punching holes and trimming edges. Therefore, the waste generated by punching holes is usually circular metal sheets, and the waste generated by trimming edges is usually strip-shaped metal sheets) generally requires the machine to stop for manual cleaning of the slide table, or special tools are used to clean the slide table, which will affect the production rhythm and processing efficiency.

[0004] Solving the above problems has become an urgent task. Summary of the Invention

[0005] In view of this, the present invention provides a two-station three-dimensional laser cutting system with a waste cleaning function.

[0006] The technical solution is as follows:

[0007] The first aspect of the present application relates to a dual-station three-dimensional laser cutting system with a waste cleaning function, comprising a bed, a rail slide conveying mechanism and two sets of beam modules, the rail slide conveying mechanism comprising a slide track extending along the length direction of the bed and penetrating the bottom of the bed, and two slides that can slide along the slide track driven by a slide drive assembly, the two sets of beam modules are parallel to each other and span the top of the bed in the width direction, and both can move along the length direction of the bed, and are characterized in that: the beam modules each include a beam, a Y-axis slide, a Z-axis sleeve and a laser cutting head, and the beam each includes two strip slides parallel to each other. And two end connecting seats fixedly connected to the two ends of the two strip slides, the gap between the two adjacent strip slides forms a Z-axis sleeve clearance groove extending along the width direction of the bed, the two end connecting seats can be installed on the bed in a translational manner, and can move along the length direction of the bed under the control of the crossbeam driving assembly, the Y-axis slide can be installed on two adjacent strip slides in a translational manner at the same time, and can move along the width direction of the bed under the control of the slide driving assembly, the Z-axis sleeve is inserted in the Z-axis sleeve clearance groove, and can be raised and lowered along the Y-axis slide under the control of the sleeve driving assembly, and the laser cutting head is installed at the bottom of the Z-axis sleeve;

[0008] The slides are each installed with a positioning tool that can move along the width direction of the bed under the drive of the tool translation assembly. The tool translation assembly includes a tool base fixedly installed on the corresponding slide and a tool translation module for driving the corresponding positioning tool to move on the tool base along the width direction of the slide track. Two waste collection boxes corresponding to the two slides are provided on one side of the width direction of the slide track. The positioning tool is synchronously connected with at least one set of waste removal mechanism for removing waste located on the upper surface of the tool base into the corresponding waste collection box.

[0009] Using the above dual-station three-dimensional laser cutting system with waste cleaning function, the crossbeams of the two crossbeam modules are of hollow structure, so that the Y-axis sliders of the two crossbeam modules can be installed in a central straddle manner on the crossbeam, thus making the centers of gravity of the Y-axis slider and the Z-axis sleeve located at the center of the crossbeam, greatly improving the stability and reliability of the Y-axis slider and the Z-axis sleeve. It not only eliminates the need for frequent deviation correction debugging but also is not prone to causing crossbeam torsional deformation, endowing the three-dimensional laser cutting machine with excellent static and dynamic characteristics. Moreover, the slide table module can provide two online-adjustable degrees of freedom in the horizontal direction, combined with multiple degrees of freedom achieved on the crossbeam module, enabling a redundant machining mode with a large number of degrees of freedom. This not only allows for more efficient laser cutting processing but also more flexible laser cutting processing, thus enabling the application to the cutting processing of more complex surfaces and obtaining higher machining accuracy. Additionally, when the positioning fixture moves along the width direction of the slide rail, it can drive each waste removal mechanism to move synchronously with it, thus pushing the waste located on the fixture base into the waste collection box. Especially for circular metal sheets, with just a slight push, they can roll out of the slide table by their own inertia. This is not only highly efficient and has little impact on the production rhythm but also the waste removal mechanism is installed on the positioning fixture and controlled by it, with a high degree of integration of the mechanical structure.

[0029] The present invention will be further described below in conjunction with embodiments and the accompanying drawings.

[0030] As Figure 1 - Figure 2 shown, a dual-station three-dimensional laser cutting system with a waste cleaning function mainly includes a bed 12, a track slide table conveying mechanism 17 and two sets of crossbeam modules.

[0031] Please refer to Figure 1 - Figure 3, sliding 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. Two waste collection bins 25 are arranged side by side at the side inlet and outlet 12d. Specifically, the bed body 12 includes five columns 12a and a top frame 12b installed 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 fixed at 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 sliding table inlets and outlets 12c are formed under both side beams 12b2 of the bed body 12, that is: the two sliding 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 of the bed body 12 supported on the two columns 12a, and the two waste collection bins 25 are located directly below the main beam 12b1, 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 directions of the two main beams 12b1 are the length direction of the bed body 12, the extending directions of the two side beams 12b2 are 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Please refer to Figure 8 - Figure 19, the crossbeam module mainly includes a crossbeam 6, a Y-axis slide 2, a Z-axis sleeve 1, and a laser cutting head 5.

[0036] The crossbeam 6 is composed of two strip-shaped slides 6b and two end connectors 6c. The two strip-shaped slides 6b and the two end connectors 6c are preferably integrally formed by a casting process, with high structural strength. Both of the two strip-shaped slides 6b are columnar or strip-shaped structures, and the two strip-shaped slides 6b are parallel to each other. The two end connectors 6c are arranged at both ends of the two strip-shaped slides 6b, that is: one end connector 6c is fixedly connected to one end of the two strip-shaped slides 6b, and the other end connector 6c is fixedly connected to the other end of the two strip-shaped slides 6b.

[0037] In this embodiment, the gap between the two strip-shaped slides 6b forms a Z-axis sleeve relief groove 6a extending in the horizontal direction, and both ends of the Z-axis sleeve relief groove 6a are defined by the two strip-shaped slides 6b. Moreover, Y-direction sliding component mounting structures 6b1 are arranged on the upper parts of the strip-shaped slides 6b, and X-direction driving device mounting structures 6c1 are arranged on the end connectors 6c, so that the centers of gravity of the Y-axis slide 2 and the Z-axis sleeve 1 are located at the center position of the crossbeam 6, greatly improving the stability and reliability of the Y-axis slide 2 and the Z-axis sleeve 1. It not only does not require frequent deviation correction debugging, but also is not easily caused by the crossbeam 6 to twist and deform, making the static and dynamic characteristics of the three-dimensional laser cutting machine excellent.

[0038] Therefore, in this embodiment, the crossbeam 6 enables the Y-axis slide 2 to be installed on the two Y-direction sliding component mounting structures 6b1, and at the same time, the Z-axis sleeve 1 can be inserted into 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-mounted installation method on the crossbeam 6.

[0039] 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 all extend along the length direction of the corresponding upper support surfaces 6b2. Support ribs 6b12 protrude from the sides of the two mounting bosses 6b11 away from each other. Second linear guide rails 7 extending along their length directions are installed on the mounting bosses 6b11. The slide rails of the second linear guide rails 7 are respectively supported on the corresponding support ribs 6b12. Therefore, not only the reliable installation of the second linear guide rails 7 is ensured, but the two second linear guide rails 7 also together form an "eight" shape structure.

[0040] In this embodiment, at least one upper support surface 6b2 is formed with 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 mounted 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 mounted on the rack mounting pad 11, and 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.

[0041] Further, the inside of the strip-shaped sliding seat 6b is a hollow structure extending along its length direction to meet the requirements of lightweight design. At the same time, a number of strengthening support ribs 6b4 distributed along its length direction are provided inside the strip-shaped sliding seat 6b, thus ensuring the structural strength of the strip-shaped sliding seat 6b.

[0042] Moreover, a number of weight-reducing openings 6b5 distributed along its length direction are formed on the side walls of the strip-shaped sliding seats 6b close to each other, and the respective strengthening support ribs 6b4 are located at both ends of the corresponding weight-reducing openings 6b5, not only meeting the requirements of lightweight design but also facilitating the welding of the strengthening support ribs 6b4.

[0043] In this embodiment, the X-direction driving device mounting structures 6c1 are respectively motor mounting grooves formed by recessing from the top surfaces of the corresponding end connectors 6c to facilitate the installation of the motors. At the same time, a number of triangular strengthening ribs 6c2 are provided on the groove walls of the two motor mounting grooves, ensuring the structural strength at the positions of the motor mounting grooves.

[0044] Further, triangular strengthening ribs 6d are provided at the four corners of the Z-axis sleeve relief groove 6a to improve the structural strength at the connection between the strip-shaped sliding seat 6b and the end connector 6c.

[0045] 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. At the same time, the cylindrical tube portion 1b is located at the lower end of the flat tube portion 1a.

[0046] In this embodiment, the flat tube portion 1a and the cylindrical tube portion 1b are coaxially arranged. Most importantly, lifting guide planes 1a1 extending in the vertical direction are provided in parallel on both sides in the width direction of the flat tube portion 1a. And the distance between the two lifting guide planes 1a1 is smaller than the diameter of the cylindrical tube portion 1b. At the same time, the cylindrical tube portion 1b protrudes radially from the two lifting guide planes 1a1. In addition, lifting control component mounting structures extending in the vertical direction are provided on the lifting guide planes 1a1.

[0047] The flat tube part 1a is used to cooperate with the Y-axis slide 2, that is, the flat tube part 1a can move up and down along the Y-axis slide 2. The cylindrical tube part 1b is used to install the laser cutting head 5. Specifically, the laser cutting head 5 extends downward from the cylindrical tube part 1b. Among them, the laser cutting head 5 adopts a traditional laser cutting head that can emit laser, and usually has one or two or more rotational degrees of freedom, which can be selected according to actual needs.

[0048] Therefore, on the premise of meeting the wiring requirements, the flat tube part 1a can be designed to be ultra-thin, 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 slide 2 that cooperates with it can also be very small, thereby reducing the size and weight of the Y-axis slide 2 and meeting the requirements of lightweight design. And because the Z-axis sleeve 1 and the Y-axis slide 2 form an irregular shaft-hole fit through the flat tube part 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 part 1a and the Y-axis slide 2 are both 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 bend and deform, and reducing the maintenance frequency and use cost.

[0049] Two wire routing relief grooves 1a2 are recessed on the inner wall of the flat tube part 1a and are arranged opposite to each other. Both of the two wire routing relief grooves 1a2 are arranged along the vertical direction on the inner side of the corresponding lifting guide plane 1a1. Therefore, while ensuring the structural strength of the flat tube part 1a itself, the middle part of the flat tube part 1a has two wire routing relief grooves 1a2 through the expanded-profile section, which is convenient for wire routing.

[0050] Furthermore, the cross-section of the flat tube part 1a is approximately rectangular. Specifically, the circumferential outer wall of the flat tube part 1a is surrounded by two relatively arranged lifting guide planes 1a1 and two relatively arranged arc surfaces 1a5. The lifting guide planes 1a1 are both plane structures, and the arc surfaces 1a5 are both arc surfaces protruding outward. The lifting guide planes 1a1 and the arc surfaces 1a5 both extend along the vertical direction. Among them, because the arc surface 1a5 is an arc-shaped thin plate structure, it is not only easy to cast, but also has higher structural strength than the conventional flat plate structure.

[0051] In this embodiment, since both of the two lifting guide planes 1a1 protrude from the cylindrical tube part 1b horizontally to both sides, the internal space of the flat tube part 1a can be effectively increased, so that more wire harnesses can pass through without increasing the width of the flat tube part 1a.

[0052] The Z-axis sleeve 1 of this embodiment is integrally formed by a casting process, and has high structural strength.

[0053] The Y-axis slide base 2 has an annular structure. Specifically, the Y-axis slide base 2 is formed by enclosing two oppositely arranged slider mounting components and two oppositely 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 rectangle, thus jointly forming an annular structure.

[0054] Each slider mounting component includes a crossbeam slider mounting base 2a and two sleeve slider mounting bases 2b. The crossbeam slider mounting base 2a includes a vertically extending vertical mounting plate 2a1 and a slider connecting plate 2a2 formed by bending 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 perpendicular to the vertical mounting plate 2a1 or inclined to the vertical mounting plate 2a1.

[0055] 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 jointly form an "eight" shape structure (matched with the second linear guide rail 7).

[0056] Therefore, when the Y-axis slide base 2 translates, it can apply pressure to the crossbeam 6 through the way of inclined plane cooperation. Compared with the structure where the slider connecting plate 2a2 is perpendicular to the vertical mounting plate 2a1 applying pressure to the crossbeam 6, the way of this embodiment can reduce the pressure borne by the crossbeam 6, so that the structural stability of the crossbeam 6 is better, and the risk of the middle part of the crossbeam 6 sagging and bending is reduced.

[0057] 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, so as to effectively improve the structural strength of the crossbeam slider mounting base 2a and avoid deformation.

[0058] Z-direction slider connection structures 2b1 are provided on all four sleeve slider mounting bases 2b. Connection bosses 2b2 adapted to the corresponding vertical mounting plates 2a1 are provided on the outer sides of the sleeve slider mounting bases 2b, and each connection boss 2b2 can be adjustably mounted on the inner side of the corresponding vertical mounting plate 2a1. Each buckle component is 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 base 2 in the circumferential direction can be adjusted.

[0059] The Y-axis slide 2 of this embodiment can be connected to the cross beam 6 in a central straddle-mounted manner by providing two Y-direction slider connection structures 2a21. Compared with the existing offset mounting 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, thus making the installation of the Y-axis slide 2 stable and reliable, without the need for frequent alignment debugging, and not easily causing 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 structure, it can be very conveniently assembled with the Z-axis sleeve 1, and can also adapt to Z-axis sleeves 1 of different sizes by replacing the latches 2c of different sizes or adjusting the connection position between the latch connecting arm 2c1 and the connecting arm slot 2b21, with good versatility. Moreover, the split-structured Y-axis slide can very conveniently correct the assembly error by adjusting the connection position between the latch connecting arm 2c1 and the connecting arm slot 2b21 and the connection position between the connecting boss 2b2 and the vertical mounting plate 2a1, and cooperate with the machining precision debugging of the later equipment.

[0060] On the outer sides of the connecting bosses 2b2, a first bolt hole array 2b22 composed of bolt holes distributed in an array is provided, 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.

[0061] At the same time, on the vertical mounting plates 2a1, two second bolt hole arrays 2a11 composed of bolt holes distributed in an array are provided, that is: the second bolt hole arrays 2a11 are composed of bolt holes distributed in multiple rows and multiple columns in an array. On the latch connecting arms 2c1, a bolt hole linear array 2c11 composed of bolt holes evenly distributed along the length direction is provided.

[0062] The apertures and spacings of adjacent bolt holes of the first bolt hole array 2b22, adjacent bolt holes of the second bolt hole array 2a11, and adjacent bolt holes of the bolt hole linear array 2c11 are all the same, and at least one bolt hole of each bolt hole linear array 2c11 communicates with the bolt holes of the corresponding first bolt hole array 2b22 and the second bolt hole array 2a11, and is 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 slide 2, only need to take out the bolts, then adjust the relative positions on the sleeve slider mounting seat 2b and the cross beam slider mounting seat 2a, and the relative position between the latch 2c and the sleeve slider mounting seat 2b. After in place, lock the bolts again, which is simple and reliable.

[0063] In this embodiment, two first linear guide rails 1c extending in the vertical direction are installed on both of the two lifting guide planes 1a1. A first rack 1d extending in the vertical direction is installed on one of the lifting guide planes 1a1. Two slider mounting assemblies are correspondingly arranged outside the two lifting guide planes 1a1, and two buckle assemblies are correspondingly arranged outside the two arc surfaces 1a5. Four Z-direction slider connection structures 2b1 are fixedly connected to the sliders of the four first linear guide rails 1c correspondingly. A first driving motor 3 is installed on the crossbeam slider mounting base 2a close to the first rack 1d, and a first driving gear 4 meshing with the first rack 1d is sleeved on the motor shaft of the first driving motor 3 in a synchronously rotating manner.

[0064] Therefore, by driving the first driving gear 4 to rotate forward and backward, the motor shaft of the first driving motor 3 can make the Z-axis sleeve 1 rise or fall along the Y-axis slide, with high control precision. 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.

[0065] 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 connecting plate 2a2 and a third bolt hole array 2a212 penetrating the slider connecting 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 rail 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.

[0066] Similarly, two Y-direction slider connection structures 2a21 are fixedly connected to the sliders of the two second linear guide rails 7 correspondingly. A second driving motor 9 is installed on the crossbeam slider mounting base 2a far from the first rack 1d, and 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 synchronously rotating manner.

[0067] 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 slide 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 slide.

[0068] 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 base 2b away from the slider connecting plate 2a2 and a fourth bolt hole array 2b12 penetrating the sleeve slider mounting base 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 rail 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.

[0069] In this embodiment, the first rack 1d and each first linear guide 1c are respectively installed on the corresponding lifting control component installation structure. Specifically, a plurality of flat cylinder part reinforcing ribs 1a3 are convexly formed on the lifting guide plane 1a1, improving 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 structure, and the first rack 1d and each first linear guide 1c are respectively installed on the 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.

[0070] Further, a circumferential reinforcing flange 1a4 is convexly formed 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 circumferential 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 circumferential reinforcing flange 1a4, thereby further improving the installation accuracy of the first rack 1d and each first linear guide 1c.

[0071] 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 convexly formed 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.

[0072] Further, a first motor mounting seat 2a4 is provided on the crossbeam slider mounting seat 2a near the first rack 1d, and the first driving motor 3 is installed 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 near the second rack 8, and the second driving motor 9 is installed on the second motor mounting seat 2a5, ensuring the reliable installation of the second driving motor 9.

[0073] In this embodiment, two mutually parallel third linear guides 13 are installed on the top of the bed body 12, and a third rack 14 parallel to each of them is installed beside the two third linear guides 13, that is: a third linear guide 13 and a 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 each end connection seat 6c of the two sets of crossbeam modules, and third driving gears 16 respectively meshing with the corresponding third racks 14 are synchronously rotated and sleeved on the motor shafts of the two third driving motors 15 of each set of crossbeam modules.

[0074] The crossbeams 6 of the two sets of crossbeam modules are installed on the corresponding sliders of the two third linear guide rails 13 in parallel, and the extending directions of the two crossbeams 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 crossbeam 6 is the Y direction, and the extending direction of the Z-axis sleeve 1 is the Z direction.

[0075] 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 crossbeam 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 crossbeam 6.

[0076] In the above structure, two third linear guide rails 13, two third racks 14 that are all installed along the length direction of the bed body 12 on the top of the bed body 12, and two third driving motors 15 that are respectively fixedly installed on the corresponding end connectors 6c form a crossbeam driving assembly. The two end connectors 6c are respectively installed on the sliders of the two third linear guide rails 13 in a one-to-one correspondence, and third driving gears 16 that are respectively meshed with the corresponding third racks 14 are synchronously rotated and sleeved on the motor shafts of the respective third driving motors 15.

[0077] Two second linear guide rails 7, a second rack 8 that are all installed along the width direction of the bed body 12, and a second driving motor 9 that is fixedly installed on the Y-axis slide 2 form a slide driving assembly. The second rack 8 and one of the second linear guide rails 7 are fixedly installed on one of the bar-shaped slides 6b in the crossbeam 6, the other second linear guide rail 7 is fixedly installed on the other bar-shaped slide 6b in the crossbeam 6, the Y-axis slide 2 is fixedly installed on the sliders of the respective second linear guide rails 7, and a second driving gear 10 that is meshed with the second rack 8 is synchronously rotated and sleeved on the motor shaft of the second driving motor 9.

[0078] A first rack 1d, at least one first linear guide rail 1c that are all installed along the vertical direction on the Z-axis sleeve 1, and a first driving motor 3 that is fixedly installed on the Y-axis slide 2 form a sleeve driving assembly. The Y-axis slide 2 is fixedly connected to the sliders of the respective first linear guide rails 1c, and a first driving gear 4 that is meshed with the first rack 1d is synchronously rotated and sleeved on the motor shaft of the first driving motor 3.

[0079] Please refer to Figure 1 - Figure 7 , in this embodiment, when there are two sliding tables 17b, the two sliding tables 17b can not only independently load and unload materials from both ends of the sliding table track 17a under the drive of their respective sliding table driving assemblies, but also cooperate as a whole to load and unload materials from one end of the sliding table track 17a.

[0080] Specifically, when large workpieces need to be processed, the two sliding tables 17b work together as a whole to load and unload materials from one end of the sliding table track 17a; when independently processing two groups of small workpieces (the two groups of small workpieces can be the same workpieces or different workpieces), the two sliding tables 17b independently load and unload materials from both ends of the sliding table track 17a.

[0081] Positioning fixtures 18 capable of moving along the width direction of the sliding table track 17a under the drive of the tooling translation assembly 19 are installed on both sliding tables 17b.

[0082] Among them, each tooling translation assembly 19 includes a tooling base 19a fixedly installed on the corresponding sliding table 17b and a tooling translation module for driving the corresponding positioning fixture 18 to move along the width direction of the sliding table track 17a on the tooling base 19a. At least one set of waste removal mechanisms 24 for removing waste on the upper surface of the tooling base 19a to one side in the width direction of the sliding table track 17a is synchronously movably connected to the positioning fixture 18.

[0083] Therefore, the sliding table module of this embodiment can provide two online-adjustable degrees of freedom in the horizontal direction, and cooperate with multiple degrees of freedom realized on the crossbeam module, so as to achieve a redundant processing mode with ultra-high degrees of freedom. It can not only perform laser cutting processing more efficiently, but also perform laser cutting processing more flexibly, so that it can be applied to the cutting processing of more complex surfaces and obtain higher processing accuracy; and when the positioning fixture 18 moves along the width direction of the sliding table track 17a, it can drive each waste removal mechanism 24 to move synchronously with it, so as to push the waste on the tooling base 19a outside the sliding table module. Especially for circular metal sheets, with a little push, they can roll out of the sliding table by their own inertia, which is not only efficient and has little impact on the production rhythm, but for strip-shaped metal sheets, the working stroke of the waste removal mechanism 24 needs to cover the tooling base 19a as much as possible; moreover, the waste removal mechanism 24 is installed on the positioning fixture 18 and is controlled by it, and the integration degree of the mechanical structure is high.

[0084] The tooling base 19a includes a material receiving plate 19a1 fixedly installed on the corresponding sliding table 17b and two guide rail mounting frames 19a2. The two guide rail mounting frames 19a2 are relatively installed on both sides of the material receiving plate 19a1 along the length direction of the sliding table track 17a. The two guide rail mounting frames 19a2 are preferably fixedly installed on the corresponding sliding table 17b and fixedly connected to the material receiving plate 19a1, ensuring the stability and reliability of the tooling base 19a.

[0085] The tooling translation module includes a fourth linear guide rail 19c installed on one of the guide rail mounting brackets 19a2, a fourth linear guide rail 19c and a fourth rack 19b installed on the other guide rail mounting bracket 19a2. Both the fourth rack 19b and the fourth linear guide rail 19c extend along the width direction of the slide table track 17a. The positioning tooling 18 includes a driving carriage 18a and a driven carriage 18b on both sides of the material receiving plate 19a1. The driving carriage 18a and the driven carriage 18b are respectively fixedly installed on the sliders of the corresponding fourth linear guide rail 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.

[0086] 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, and the control accuracy is high. Further, the fourth motor 19d is preferably a servo motor, which can further improve the precision control of the translation of the positioning tooling 18.

[0087] In this embodiment, a set of waste removal mechanisms 24 for removing the waste on the upper surface of the material receiving plate 19a1 to one side in the width direction of the slide table track 17a are installed on both the driving carriage 18a and the driven carriage 18b, so that the cleaning effect on the upper surface of the material receiving plate 19a1 is better.

[0088] Two material receiving grooves 19a11 are respectively recessed on the upper surface of the material receiving plate 19a1 and located below the corresponding waste removal mechanisms 24, so as to reliably collect the waste generated by laser cutting. At the same time, each waste removal mechanism 24 includes a connection component 24a installed on the corresponding driving carriage 18a or driven carriage 18b and a removal component 24b for removing the waste in the corresponding material receiving groove 19a11 to one side in the width direction of the slide table track 17a. Each group of removal components 24b independently removes the waste in the material receiving groove 19a11, and the reliability is high.

[0089] Specifically, the bottom of the material receiving groove 19a11 is recessed to form a plurality of guide slots 19a12 that penetrate the material receiving plate 19a1 side by side along the width direction of the sliding table track 17a. The rejection assembly 24b includes a push-pull shaft 24b1 extending along the length direction of the sliding table track 17a, a rejection push block 24b2 slidably installed in the guide slot 19a12 in a one-to-one correspondence, and a push-pull crank 24b3 hinged to the same end of each rejection push block 24b2 in a one-to-one correspondence. One end of each push-pull crank 24b3 away from the rejection push block 24b2 is hinged to the corresponding push-pull shaft 24b1. The connection assembly 24a includes a push-pull plate 24a1 fixedly connected to the corresponding active carriage 18a or driven carriage 18b and a push-pull link 24a2 hinged to the corresponding push-pull plate 24a1. One end of each push-pull link 24a2 away from the push-pull plate 24a1 is hinged to the corresponding push-pull shaft 24b1.

[0090] Therefore, when the active carriage 18a and the driven carriage 18b translate synchronously, each push-pull plate 24a1 can push and pull the corresponding push-pull shaft 24b1 through the corresponding push-pull link 24a2. The push-pull shaft 24b1 then synchronously pushes and pulls the rejection push block 24b2 through each push-pull crank 24b3, so that the waste in each guide slot 19a12 can be pushed to the outside of the sliding table module. Since the cutting waste is usually a metal sheet (either circular or strip-shaped) generated by punching, and the width of the guide slot 19a12 is designed to be smaller than the metal sheet, it can ensure that the metal sheet is placed obliquely in the guide slot 19a12 and is easily pushed by the rejection push block 24b2. If the metal sheet is circular, with a slight push from the rejection push block 24b2 on the circular metal sheet, the circular metal sheet can roll outside the guide slot 19a12 under the support of the side wall of the guide slot 19a12 by using its own inertia.

[0091] Furthermore, in order to make the metal sheet easier to be pushed out of the guide slot 19a12, in this embodiment, in the same material receiving groove 19a11: each guide slot 19a12 is downwardly inclined synchronously and variably from the end of each rejection push block 24b2 close to the push-pull shaft 24b1 to the other end. Since each guide slot 19a12 is designed to be inclined downward toward the output end, whether it is a circular metal sheet or a strip-shaped metal sheet, the rejection push block 24b2 only needs to apply a relatively small thrust as set, and the circular metal sheet and the strip-shaped metal sheet can smoothly slide out along the guide slot 19a12 under the action of their own gravity and inertia, which not only improves the cleaning ability and cleaning efficiency, but also can better avoid the jamming problem.

[0092] Furthermore, in order to make the posture of the metal sheet in the material guiding slit 19a12 easier to be pushed by the material removing push block 24b2, in this embodiment, the two side walls of the material guiding slit 19a12 are mirror - set, and the material guiding slit 19a12 is composed of an inclined section 19a121 and a vertical section 19a122 which are distributed from bottom to top. Specifically, in the same material guiding slit 19a12: the heights of the inclined sections 19a121 at each position are equal, and the heights of the vertical sections 19a122 at each position are also equal; among them, the two inclined sections 19a121 are both inclined - plane structures, and the distance between the two inclined sections 19a121 gradually increases towards the direction close to the bottom of the slot, that is: the cross - section of the material guiding slit 19a12 at the positions of the two inclined sections 19a121 is in a trapezoidal structure; the two vertical sections 19a122 are both vertical - plane structures, that is: the cross - section of the material guiding slit 19a12 at the positions of the two vertical sections 19a122 is in a rectangular structure, so that the metal sheet generated by laser cutting can be supported at the position of the inclined section 19a121 and has a certain angle with the vertical section 19a122, and thus is more easily pushed by the material removing push block 24b2.

[0093] Correspondingly, each material removing push block 24b2 includes a connecting arm 24b21 hinged to the corresponding push - pull crank 24b3 and a removing block 24b22 integrally formed at one end of the corresponding connecting arm 24b21 away from the push - pull crank 24b3. At the lower part of the removing block 24b22, a reduced - diameter section 24b221 adapted to the corresponding two vertical sections 19a122 and a trapezoidal - block section 24b222 adapted to the corresponding two inclined sections 19a121 are integrally formed. Therefore, the metal sheet generated by laser cutting will be inclinedly supported in the material guiding slit 19a12 and will not completely adhere to the bottom or side wall of the material guiding slit 19a12, enabling the material removing push block 24b2 to very easily push the metal sheet in the material guiding slit 19a12 and avoiding the problem of jamming.

[0094] Furthermore, in this embodiment, the upper part of the removing block 24b22 is designed to be wider, so that the gap between the upper parts of adjacent removing blocks 24b22 is very small (usually much smaller than the diameter or width of the metal sheet), so that the waste materials that do not fall into the material guiding slit 19a12 can be pushed away together, ensuring the thoroughness of waste - material removal.

[0095] In this embodiment, in order to ensure the stability of the operation of the push - pull shaft 24b1, push - pull shaft guiding grooves 19a13 adapted to the corresponding push - pull shafts 24b1 are provided on the two side walls of the material receiving groove 19a11, and the two ends of each push - pull shaft 24b1 are respectively slidably fitted into the corresponding push - pull shaft guiding grooves 19a13, thus ensuring the synchronism of the operation of each material removing push block 24b2 and avoiding the problem of jamming.

[0096] 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, an active carriage movable mounting plate 18a3, and an active carriage connecting seat 18a4 all mounted on the active carriage base 18a1. The active carriage connecting seat 18a4 is fixedly mounted at one end of the active carriage base 18a1 and is connected to the corresponding waste removing mechanism 24. The active carriage fixed mounting plate 18a2 is fixedly mounted at the other end of the active carriage base 18a1. 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 mounted in the first elongated hole 18a11 through at least two bolts that can be locked or unlocked. The fourth motor 19d is mounted beside the active carriage connecting seat 18a4.

[0097] 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, a driven carriage movable mounting plate 18b3, and a driven carriage connecting seat 18b4 all mounted on the driven carriage base 18b1. The driven carriage connecting seat 18b4 is fixedly mounted at one end of the driven carriage base 18b1 and is connected to the corresponding waste removing mechanism 24. The driven carriage fixed mounting plate 18b2 is fixedly mounted at the other end of the driven carriage base 18b1. 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 mounted in the second elongated hole 18b11 through at least two bolts that can be locked or unlocked.

[0098] 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 is possible to adapt to workpieces of different sizes, and the versatility is good.

[0099] Furthermore, in one of 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, and in the other, a slot hole array composed of slot holes distributed in an array is provided, which further improves the applicability to workpieces of different sizes.

[0100] In this embodiment, the slide table drive assembly includes a fifth rack 21 and two fifth linear guide rails 20 that are installed in parallel on the slide table rail 17a, and a fifth motor 22 that is installed on the slide table 17b. The two slide tables 17b are respectively fixedly installed on the corresponding sliders of the two fifth linear guide rails 20. A fifth drive gear 23 that meshes with the fifth rack 21 is sleeved on the motor shaft of the fifth motor 22 in a synchronously rotating manner. Therefore, by driving the fifth drive gear 23 to rotate forward and backward, the motor shaft of the fifth motor 22 can drive the translation of the slide 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 slide table 17b.
