Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and particularly relates to a dual-slide multi-purpose male-female structure and a three-dimensional laser cutting machine. Background Art

[0002] 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 dual-channel three-dimensional laser cutting machines with dual laser cutting heads. However, existing dual-channel three-dimensional laser cutting machines usually only have one slide, that is: existing dual-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.

[0003] Therefore, on the market, a series of three-dimensional laser cutting systems with dual slides (i.e., dual-station three-dimensional laser cutting systems) such as those with publication number CN220698527U have emerged. The two slides can both independently perform the loading and unloading operations on two groups of small workpieces (the two groups of small workpieces can be the same workpieces or different workpieces), and can also cooperate to perform the loading and unloading on large workpieces, so that the two laser cutting heads can both process two groups of small workpieces simultaneously and can also cooperate to process large workpieces.

[0004] The applicant of this application has designed a series of Chinese invention patent applications such as those with application numbers CN2025101446889, CN 2025102026377, and CN2025102026292, all of which are three-dimensional laser cutting systems with dual slides.

[0005] In the above-mentioned prior art, due to defects in the structural design, not only when the two slides cooperate to process large workpieces, it is impossible to ensure the stability and reliability of the overall combination, thus making it difficult to ensure the accuracy of laser cutting processing, resulting in the three-dimensional laser cutting system being unable to be applied to application scenarios with ultra-high processing accuracy, but also when the two slides independently load, unload, and process small workpieces, since there is no anti-collision design between the two slides, the two slides occasionally collide. Especially when one slide is cooperating with the crossbeam module to process a workpiece, being collided by the other slide will inevitably easily cause a small displacement, thus leading to problems with processing quality and equipment damage. Summary of the Invention

[0006] In view of this, the present invention provides a dual-slide multi-purpose male-female structure and a three-dimensional laser cutting machine.

[0007] The technical solution is as follows:

[0008] The first aspect of the present application relates to a dual-slide multi-purpose male-female structure, including a slide rail and two slides that can slide along the slide rail driven by a slide driving assembly. At least one pair of male bases and female bases that are directly opposite to each other are respectively installed on the outer edges of the two slides on the side where they are close to each other. First electromagnets and at least one precise positioning groove are provided on each female base. Second electromagnets, precise positioning blocks respectively corresponding to each precise positioning groove, and a positioning block driving device for driving each precise positioning block to move synchronously are provided on each male base. Each first electromagnet is directly opposite to each second electromagnet, and the magnetic poles of each first electromagnet and the magnetic poles of the corresponding second electromagnet can be synchronously switched to be the same or opposite;

[0009] When the magnetic poles of each first electromagnet and the magnetic poles of the corresponding second electromagnet are opposite to each other and the two slides approach each other, each first electromagnet can be adsorbed to the corresponding second electromagnet, so that the positioning block driving device can drive each precise positioning block to be synchronously inserted into the corresponding precise positioning groove in a beveled surface matching manner.

[0010] With the above dual-slide multi-purpose male-female structure, when the two slides need to cooperate to process large workpieces together, first switch the magnetic poles of each pair of first electromagnets and second electromagnets to be opposite. Therefore, when the two slides approach each other, rapid initial positioning and preliminary combination of the two slides can be achieved through the mutual adsorption of each pair of first electromagnets and second electromagnets. Moreover, the magnetic induction signals of the first electromagnets and second electromagnets can also be used as the start signals of the positioning block driving devices, so that each positioning block driving device drives each precise positioning block to be respectively inserted into the corresponding precise positioning groove. Due to the beveled surface matching of each precise positioning block and precise positioning groove, extremely precise positioning and extremely reliable combination of the two slides can be achieved, so that the two slides are completely rigidly combined into one body, and then extremely high-precision laser cutting processing can be achieved in cooperation with the crossbeam module, meeting the needs of ultra-high processing precision application scenarios; when the two slides independently load and unload and process small workpieces respectively, switch the magnetic poles of each pair of first electromagnets and second electromagnets to be the same. The repulsive force generated between each pair of first electromagnets and second electromagnets increases rapidly as the distance between the two slides decreases, so that extremely reliable physical anti-collision between the two slides can be achieved, and further the problems of processing quality and equipment damage caused by the collision of the two slides can be avoided.

[0011] The second aspect of the present application relates to a three-dimensional laser cutting machine, including a bed body, two sets of crossbeam modules, and the above-mentioned double-slide multi-purpose male-female structure. Both ends of the bed body in the length direction are provided with slide table inlets and outlets. The slide table track passes through the two slide table inlets and outlets simultaneously in the length direction. 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. Each crossbeam module includes a crossbeam, a Y-axis slide seat, a Z-axis sleeve, and a laser cutting head. The crossbeam extends along the width direction of the bed body, and both ends thereof can move along the length direction of the bed body under the control of a crossbeam drive assembly. The Y-axis slide seat can move along the length direction of the crossbeam under the control of a slide seat drive assembly. The Z-axis sleeve can move up and down along the Y-axis slide seat under the control of a sleeve drive assembly. The laser cutting head is installed at the bottom of the Z-axis sleeve.

[0012] By using the above three-dimensional laser cutting machine, all the advantages of the above-mentioned double-slide multi-purpose male-female structure are possessed. Brief Description of the Drawings

[0036] The present invention will be further described below in conjunction with embodiments and drawings.

[0037] Embodiment 1:

[0038] As Figures 1 - 7 shown, a double-slide multi-purpose male-female structure includes a slide rail 17a and two slides 17b that can slide along the slide rail 17a under the drive of a slide drive assembly. In this embodiment, the slide rail 17a extends in the X-axis direction.

[0039] The slide drive assembly includes a fifth rack 21, two fifth linear guide rails 20 which are installed on the slide rail 17a in parallel, and a fifth motor 22 which is installed on the slide 17b respectively. The two slides 17b are fixedly installed on the corresponding sliders of the two fifth linear guide rails 20. A fifth drive gear 23 which meshes with the fifth rack 21 is sleeved on the motor shaft of the fifth motor 22 synchronously. 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 17b, and the control precision is high. Further, the fifth motor 22 preferably adopts a servo motor, which can further improve the precision control of the translation of the slide 17b.

[0040] In this embodiment, at least one pair of male bases 43 and female bases 40 which are exactly opposite to each other are respectively installed on the outer edges of the two slides 17b on the sides close to each other. A first electromagnet 41 and at least one precise positioning groove 42 are arranged on each female base 40. A second electromagnet 44, a precise positioning block 45a corresponding to each precise positioning groove 42 respectively, and a positioning block driving device 46 for driving each precise positioning block 45a to move synchronously are arranged on each male base 43. Each first electromagnet 41 and each second electromagnet 44 are exactly opposite to each other, and the magnetic poles of each first electromagnet 41 and the magnetic poles of the corresponding second electromagnet 44 can be switched synchronously to be the same or opposite. Generally speaking, by changing the direction of the current, the magnetic poles of the first electromagnet 41 and the second electromagnet 44 can be changed.

[0041] When the magnetic poles of each first electromagnet 41 and the magnetic poles of the corresponding second electromagnet 44 are all opposite and the two slides 17b approach each other, each first electromagnet 41 can be adsorbed to the corresponding second electromagnet 44 respectively, so that the positioning block driving device 46 can drive each precise positioning block 45a to be embedded into the corresponding precise positioning groove 42 in a bevel matching manner synchronously.

[0042] Specifically, when two sliding tables 17b need to cooperate to process large workpieces, first switch the magnetic poles of each pair of first electromagnets 41 and second electromagnets 44 to be opposite. Thus, when the two sliding tables 17b approach each other, through the mutual adsorption of each pair of first electromagnets 41 and second electromagnets 44, rapid initial positioning and preliminary combination of the two sliding tables 17b can be achieved. Moreover, the magnetic induction signals of the first electromagnets 41 and the second electromagnets 44 can also serve as the start signals for the positioning block driving devices 46, enabling each positioning block driving device 26 to drive each precise positioning block 45a to be respectively inserted into the corresponding precise positioning groove 42. Due to the inclined surface fit between each precise positioning block 45a and the precise positioning groove 42, extremely precise positioning and extremely reliable combination of the two sliding tables 17b can be achieved, so that the two sliding tables 17b are completely rigidly combined into one body. Furthermore, extremely high-precision laser cutting processing can be achieved in cooperation with the crossbeam module, meeting the needs of ultra-high processing precision application scenarios; when the two sliding tables 17b are independently loading and unloading and processing small workpieces, switch the magnetic poles of each pair of first electromagnets 41 and second electromagnets 44 to be the same. The repulsive force generated between each pair of first electromagnets 41 and second electromagnets 44 rapidly increases as the distance between the two sliding tables 17b decreases. Thus, extremely reliable physical anti-collision between the two sliding tables 17b can be achieved, and further, problems such as processing quality and equipment damage caused by the collision of the two sliding tables 17b can be avoided.

[0043] Please refer to Figures 4 - 7 , a translation guide rod 47 extending horizontally in the direction approaching the corresponding male base 43 is fixedly installed on the female base 40. A translation sleeve 48 capable of moving axially along it and a return compression spring 49 for making the translation sleeve 48 have an outward movement tendency are sleeved on the translation guide rod 47. The two ends of the return compression spring 49 are respectively fixedly connected to the inner end of the translation sleeve 48 and the inner end of the translation guide rod 47. An electromagnet mounting seat 50 is fixedly sleeved on the translation sleeve 48, and the first electromagnet 41 is fixedly installed on the side of the electromagnet mounting seat 50 close to the corresponding second electromagnet 44.

[0044] It should be noted that if the first electromagnet 41 is rigidly installed, regardless of the possibility that the contact between the first electromagnet 41 and the corresponding second electromagnet 44 may not achieve a complete rigid connection due to surface sliding, assuming that a rigid connection can be achieved through the adsorption force between each first electromagnet 41 and the corresponding second electromagnet 44, but due to more impurities or waste in the laser cutting environment, if the first electromagnet 41 and the second electromagnet 44 are worn or adsorbed with impurities, it will inevitably lead to a large positioning error. If on the basis of the rigid installation method of the first electromagnet 41, the precise positioning structure of the cooperation between the above-mentioned precise positioning block 45a and the inclined plane of the precise positioning groove 42 is added, the two sliding tables 17b can achieve a complete rigid connection, so that the force-bearing and force-transmitting performance is better, ensuring the static / dynamic stiffness of the sliding table 17b and the overall structure; but also due to more impurities or waste in the laser cutting environment, if the first electromagnet 41 and the second electromagnet 44 are worn or adsorbed with impurities, it will inevitably lead to the situation that the precise positioning block 45a cannot be embedded in the precise positioning groove 42 or the embedding depth is not in place, resulting in a large positioning error.

[0045] Therefore, in this embodiment, rough positioning is achieved through the elastic installation method of the first electromagnet 41, and the start signal of the positioning block driving device 46 is provided, and then the final precise positioning is achieved through the inclined plane cooperation between the precise positioning block 45a and the precise positioning groove 42. Among them, the first electromagnet 41 adopts a sliding fit and elastic installation method. Not only does the reset compression spring 49 make the first electromagnet 41 tend to stay at the outer end of the translation guide rod 47, thus ensuring the stability and reliability of the combination of the first electromagnet 41 and the corresponding second electromagnet 44, but also it can play a role in buffering and absorbing energy for the collision between the first electromagnet 41 and the corresponding second electromagnet 44, and at the same time provides an adjustment displacement amount for the precise positioning of the inclined plane cooperation between the precise positioning block 45a and the precise positioning groove 42, ensuring the final positioning accuracy.

[0046] In this embodiment, the circumferential groove walls of the precise positioning groove 42 are all surrounded by four inclined planes arranged in pairs opposite to each other, so that the cross-section of the precise positioning groove 42 is rectangular, and the cross-sectional area of the precise positioning groove 42 gradually increases from the groove bottom to the groove opening. The inclination angles of the circumferential groove walls of the precise positioning groove 42 are all less than or equal to 5°. The circumferential side walls of the precise positioning block 45a that can be embedded in the precise positioning groove 42 are all surrounded by four inclined planes that respectively cooperate with the inclined planes of the corresponding groove walls of the precise positioning groove 42. Correspondingly, the inclination angles of the circumferential side walls of the precise positioning block 45a that can be embedded in the precise positioning groove 42 are equal to the inclination angles of the circumferential groove walls of the precise positioning groove 42, and are also less than or equal to 5°. Therefore, through the inclined plane cooperation of the precise positioning block 45a and the precise positioning groove 42 with a very small angle, it can effectively reduce the driving force of the positioning block driving device 46, so that a positioning block driving device 46 with a small output thrust can be selected, and at the same time, the positioning accuracy is improved.

[0047] Further, the positioning block driving devices 46 are all positioning block driving cylinders fixedly installed on the corresponding male bases 43. The outer ends of the piston rods of the positioning block driving cylinders are all fixedly installed with positioning block mounting assemblies 45. Precision positioning blocks 45a that are respectively adapted to the corresponding precise positioning grooves 42 are integrally formed on the positioning block mounting assemblies 45. The precision positioning blocks 45a are all hollow structures with openings at one end close to the corresponding positioning block driving cylinders, ensuring a lightweight design. At the same time, dust-proof plug blocks 45b are installed at the opening sections of the precision positioning blocks 45a to prevent dust and slag accumulation.

[0048] Further, dust-proof baffle plates 51 adapted to the positioning block mounting assemblies 45 are installed on the male bases 43. When the piston rods of the positioning block driving cylinders retract to the limit positions, the dust-proof baffle plates 51 can block the gaps between the positioning block mounting assemblies 45 and the male bases 43, thereby minimizing the entry of waste slag and dust generated by laser cutting into the precise positioning grooves 42 and ensuring the positioning accuracy.

[0049] Please refer to Figure 2 , on the outer edges of the two sliding tables 17b on their mutually approaching sides, dust-proof plates 52 of the sliding tables are respectively installed. The dust-proof plates 52 of the sliding tables all have shielding portions 52a that first extend upward and then extend horizontally outward beyond the corresponding male bases 43 or female bases 40. When the two sliding tables 17b independently process workpieces, the shielding portions 52a can shield the waste slag and dust generated by laser cutting as much as possible, protecting the internal male bases and their affiliated structures or female bases and their affiliated structures. When the first electromagnets 41 respectively adsorb to the corresponding second electromagnets 44, the two shielding portions 52a enclose to form an arch structure, further enhancing the protection effect on the internal male bases and their affiliated structures and female bases and their affiliated structures.

[0050] Further, end baffle plates 52b are provided at both ends of the shielding portions 52a. When the first electromagnets 41 respectively adsorb to the corresponding second electromagnets 44, the two end baffle plates 52b at both ends are also mutually engaged, further improving the shielding effect.

[0051] Embodiment 2:

[0052] Please refer to Figures 1 - 23 , a three-dimensional laser cutting machine mainly includes a machine body 12, two sets of crossbeam modules, and the double-sliding-table multi-purpose male-female structure of Embodiment 1.

[0053] Both ends of the bed body 12 in the length direction are provided with slide table inlets and outlets 12c, and one side of the bed body 12 in the width direction is provided with a side inlet and outlet 12d. 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 two relatively arranged main beams 12b1 and two relatively arranged side beams 12b2 to form a rectangular structure. 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 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 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. 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.

[0054] In this embodiment, each column 12a includes a column body 12a1 extending in the vertical direction, 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 plurality of column strengthening plates 12a4 extending in the vertical direction are installed on the circumference of the column body 12a1. The tops of the column strengthening plates 12a4 are respectively fixedly connected to the corresponding column top plates 12a2, and the bottoms of the column strengthening plates 12a4 are respectively fixedly connected to the corresponding column bottom plates 12a3. Therefore, the structural strength of each column 12a is greatly improved, and thus the structural strength of the bed body 12 is further improved. Further, in order to improve the structural strength of the bed body 12, top frame strengthening 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 strengthening triangular plates 12b4 are also provided at the connection positions between the top frame 12b and each column 12a.

[0055] Please refer to Figures 10 - 20, the crossbeam module mainly includes a crossbeam 6, a Y-axis slide 2, a Z-axis sleeve 1 and a laser cutting head 5. The crossbeam 6 is composed of two strip slides 6b and two end connecting seats 6c. The two strip slides 6b and the two end connecting seats 6c are preferably integrally formed by a casting process, and have high structural strength. The two strip slides 6b are both columnar or strip structures, and the two strip slides 6b are parallel to each other. The two end connecting seats 6c are arranged at both ends of the two strip slides 6b, that is: one of the end connecting seats 6c is fixedly connected to one end of the two strip slides 6b, and the other end connecting seat 6c is fixedly connected to the other end of the two strip slides 6b. 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, a Y-axis sliding component mounting structure 6b1 is provided on the upper part of the strip slide 6b, and an X-axis driving device mounting structure 6c1 is provided on the end connecting seat 6c, so that the center of gravity of the Y-axis slide 2 and the Z-axis sleeve 1 is located at the center position of the beam 6, which greatly improves the stability and reliability of the Y-axis slide 2 and the Z-axis sleeve 1. There is no need for frequent correction and debugging, and it is not easy to cause torsional deformation of the beam 6, which makes the static and dynamic characteristics of the three-dimensional laser cutting machine excellent.

[0056] Therefore, the crossbeam 6 of this embodiment 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 clearance groove 6a, thereby cooperating with the Y-axis slide 2 to realize a centrally placed straddle-type installation on the crossbeam 6.

[0057] Furthermore, the upper parts of the two strip-shaped slide seats 6b have upper support surfaces 6b2 that are both inclined, and the two upper support surfaces 6b2 are symmetrically inclined downward in a direction away from each other, that is, the two upper support surfaces 6b2 together form an "eight"-shaped structure. At the same time, the Y-axis sliding assembly mounting structure 6b1 includes mounting bosses 6b11 protruding from the corresponding upper support surfaces 6b2, and the mounting bosses 6b11 extend along the length direction of the corresponding upper support surfaces 6b2. The two mounting bosses 6b11 are protruding on the side away from each other to form support ribs 6b12, and the mounting bosses 6b11 are mounted with second linear guides 7 extending along the length direction thereof, and the slide rails of each second linear guide 7 are respectively supported on the corresponding support ribs 6b12. Therefore, not only is the reliable installation of the second linear guide 7 guaranteed, but the two second linear guides 7 also together form an "eight"-shaped structure.

[0058] 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 in 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 in the length direction of the rack mounting pad 11 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.

[0059] Furthermore, the interiors of the strip-shaped sliding seats 6b are all hollow structures extending in their length directions to meet the requirements of lightweight design. At the same time, a number of reinforcing support ribs 6b4 distributed in the length direction of the strip-shaped sliding seats 6b are provided inside the strip-shaped sliding seats 6b, thereby ensuring the structural strength of the strip-shaped sliding seats 6b. Among them, since weight-reducing openings 6b41 are also provided on the reinforcing support ribs 6b4, the overall lightweight is further improved.

[0060] Moreover, a number of weight-reducing openings 6b5 distributed in the length direction of the upper support surface 6b2 are provided on the upper support surface 6b2, and the respective reinforcing 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 and installation of the reinforcing support ribs 6b4.

[0061] 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 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.

[0062] 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. 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.

[0063] The flat tube portion 1a is used to cooperate with the Y-axis slide 2, that is: the flat tube portion 1a can move up and down along the Y-axis slide 2. The cylindrical tube portion 1b is used to mount the laser cutting head 5. Specifically, the laser cutting head 5 extends downward from the cylindrical tube portion 1b. Among them, the laser cutting head 5 adopts a traditional laser cutting head that can excite laser, and usually has one or two or more rotational degrees of freedom, which can be selected according to actual needs.

[0064] Therefore, on the premise of meeting the wire routing 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 slide 2 that cooperates with it can also be very small, thereby reducing the size and weight of the Y-axis slide 2, 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 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 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, reducing the maintenance frequency and use cost.

[0065] Two wire routing relief grooves 1a2 are recessed on the inner wall of the flat tube portion 1a and are arranged opposite to each other. Both of the two wire routing relief grooves 1a2 extend in the vertical direction and are arranged inside the corresponding lifting guide planes 1a1. Therefore, while ensuring the structural strength of the flat tube portion 1a itself, the middle part of the flat tube portion 1a has two wire routing relief grooves 1a2 through the enlarged-diameter profile, which is convenient for wire routing. Further, 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 surfaces protruding outward. The lifting guide planes 1a1 and the arc surfaces 1a5 both extend in 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 compared with the conventional flat plate structure. In this embodiment, because 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, so that more wire harnesses can pass through without increasing the width of the flat tube portion 1a.

[0066] The Z-axis sleeve 1 of this embodiment is integrally formed by a casting process, and has high structural strength.

[0067] 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.

[0068] 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 arranged perpendicular to the vertical mounting plate 2a1 or can be arranged obliquely to the vertical mounting plate 2a1. Further, 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 a "V" shape structure (matched with the second linear guide 7).

[0069] 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 that 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 being concave and bent is reduced.

[0070] Further, 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.

[0071] 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.

[0072] 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, nor is it likely to cause torsional deformation of the cross beam 6, resulting in excellent static and dynamic characteristics of the three-dimensional laser cutting machine. 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 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 and coordinate with the processing precision debugging of the later equipment by adjusting the connection position between the latch connecting arm 2c1 and the connecting arm slot 2b21, as well as the connection position between the connecting boss 2b2 and the vertical mounting plate 2a1.

[0073] 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. 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 array 2a11 is 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.

[0074] 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 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 remove the bolts, then adjust the relative positions on the sleeve slider mounting seat 2b and the cross beam slider mounting seat 2a, as well as the relative position between the latch 2c and the sleeve slider mounting seat 2b. After positioning, lock the bolts again, which is simple and reliable.

[0075] 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 seat 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 synchronously and rotatably.

[0076] 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.

[0077] 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. 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 seat 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 synchronously and rotatably.

[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 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.

[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 far from the slider connecting plate 2a2 and a fourth bolt hole array 2b12 penetrating 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 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.

[0080] 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, 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 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.

[0081] Furthermore, a circular 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 circular 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 circular reinforcing flange 1a4, thereby further improving the installation accuracy of the first rack 1d and each first linear guide 1c.

[0082] Furthermore, 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. Each annular reinforcing rib 1b1 and each axial reinforcing rib 1b2 together form a grid-like structure, thereby effectively improving the structural strength of the cylindrical part 1b.

[0083] Furthermore, 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 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 close to 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.

[0084] High-rigidity linear guides 31 extending along the length direction of the crossbeam 6 are fixedly installed in parallel on both side walls of the Z-axis bushing relief groove 6a, that is: high-rigidity linear guides 31 are installed on one side wall of each of the two strip-shaped sliders 6b close to each other. At the same time, high-rigidity support blocks 32 extending along the width direction of the crossbeam 6 are fixedly installed on both sides of the Y-axis slider 2 along the length direction of the crossbeam 6. Both ends of the high-rigidity support blocks 32 are respectively fixedly connected and supported between the corresponding sliders of the two high-rigidity linear guides 31, that is: support block mounting seats 2b3 adapted to the high-rigidity support blocks 32 are provided at the lower parts of the four slider connection structures 2b1, and the high-rigidity support blocks 32 are fixedly installed in pairs of two of the four support block mounting seats 2b3.

[0085] Therefore, in this embodiment, not only high-rigidity linear guides 31 arranged along the length direction are added to both side walls of the relief groove 6a of the Z-axis sleeve, which is equivalent to adding two straighteners to the cross beam 6, but also two high-rigidity support blocks 32 fixedly connected to the Y-axis slide 2 and the sliders of the two high-rigidity linear guides 31 are added. The two high-rigidity support blocks 32 and the two high-rigidity linear guides 31 form a dynamic quadrilateral support structure. By synchronously moving with the Y-axis slide 2, the two high-rigidity support blocks 32 can not only serve as two dynamic stiffeners to improve the structural strength of the cross beam 6, increase the low-order modal frequency of the cross beam 6, thereby enhancing the static and dynamic stiffness of the cross beam 6, but also serve as two dynamic on-line straighteners to straighten the cross beam 6 by moving back and forth. As a result, even after long-term use, it is extremely difficult for the cross beam 6 to bend and twist. At the same time, the two high-rigidity support blocks 32 and the two high-rigidity linear guides 31 also greatly increase the structural strength of the connection between the cross beam 6 and the Y-axis slide 2, adding a new force transmission path and realizing an integrated coupling design, thus significantly improving the load-bearing capacity of the entire cross beam module and enabling the three-dimensional laser cutting machine to have excellent static and dynamic characteristics.

[0086] Further, on the side walls of the two strip-shaped slides 6b close to each other, guiding support grooves 6b6 adapted to the corresponding end parts of the high-rigidity support blocks 32 are recessed along the length direction. The two high-rigidity linear guides 31 are respectively fixedly installed at the bottom of the corresponding guiding support grooves 6b6. The two ends of the high-rigidity support block 32 are respectively inserted into the corresponding guiding support grooves 6b6, and the upper and lower side walls of the two ends of the high-rigidity support block 32 are respectively in surface contact with the two side wall surfaces of the corresponding guiding support grooves 6b6, that is: the upper side wall of the high-rigidity support block 32 and the upper side wall of the guiding support groove 6b6 form a surface contact, and the lower side wall of the high-rigidity support block 32 and the lower side wall of the guiding support groove 6b6 form a surface contact. Through such a design, the supporting and shaping effects of the two high-rigidity support blocks 32 on the two strip-shaped slides 6b can be greatly improved, so that the entire cross beam module has more excellent static and dynamic characteristics.

[0087] It should be noted that a plurality of bolt mounting holes 6b7 are opened at the bottom of the guiding support groove 6b6, and the high-rigidity linear guide 31 is locked in the corresponding bolt mounting holes 6b7 by bolts, ensuring the reliable installation of the high-rigidity linear guide 31 and making the assembly process very convenient.

[0088] At the bottom of the high-rigidity support blocks 32, vision system brackets 37 are installed. On the vision system brackets 37, online adjustment motors 34 are fixedly installed. On the motor shafts of the online adjustment motors 34, online camera brackets 35 are fixedly installed. On the online camera brackets 35, online vision cameras 36 are fixedly installed. Therefore, it is possible to perform online perspective detection on the workpiece being processed to assist in achieving higher-quality three-dimensional cutting processing. Moreover, since the online adjustment motor 34 can drive the online vision camera 36 to rotate through the online camera bracket 35, the range of perspective detection is greatly increased, and at the same time, detection dead angles can be avoided.

[0089] On one side of the high-rigidity support blocks 32 away from the Z-axis sleeve 1, first oil pressure buffers 33 extending away from the Z-axis sleeve 1 are installed. On one side of the end connection seats 6c close to the Z-axis sleeve 1, first force sensors 34 facing the adjacent first oil pressure buffers 33 are installed. When the first oil pressure buffer 33 abuts against the corresponding first force sensor 34, the first oil pressure buffer 33 can first play a buffering role, and at the same time, it can trigger the first force sensor 34 to send a shutdown signal, thereby avoiding the collision between the Y-axis slide 2 and the crossbeam 6.

[0090] Furthermore, the high-rigidity support block 32 can be composed of a combination of multiple small blocks fixedly connected, which greatly improves the convenience of assembling with the counterparty parts. At the same time, each small block is in a hollow grid structure on the premise of meeting the structural strength requirements, ensuring the overall lightweight design of the crossbeam module, reducing the load on the crossbeam 6, and thus further reducing the risk of deformation of the crossbeam 6.

[0091] In this embodiment, two mutually parallel third linear guide rails 13 are installed on the top of the bed body 12. Beside the two third linear guide rails 13, third racks 14 parallel to them are installed, that is: on the top of the main beam 12b1, a third linear guide rail 13 and a third rack 14 are installed along its length direction. At the same time, third drive motors 15 are installed on each end connection seat 6c of the two crossbeam modules. On the motor shafts of the two third drive motors 15 of each crossbeam module, third drive gears 16 respectively meshing with the corresponding third racks 14 are sleeved and rotate synchronously.

[0092] The crossbeams 6 of the two crossbeam modules are installed on the corresponding sliders of the two third linear guide rails 13 in parallel. Moreover, 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.

[0093] 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.

[0094] In the above structure, two third linear guide rails 13, two third racks 14 which 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 respectively fixedly installed on the corresponding end connecting seats 6c form a cross beam driving assembly. The two end connecting seats 6c are respectively installed on the sliders of the two third linear guide rails 13, and third driving gears 16 which are respectively meshed with the corresponding third racks 14 are synchronously rotated and sleeved on the motor shafts of the third driving motors 15.

[0095] Two second linear guide rails 7, a second rack 8 which are all installed along the width direction of the bed body 12, and a second driving motor 9 fixedly installed on the Y-axis slide base 2 form a slide base driving assembly. The second rack 8 and one of the second linear guide rails 7 are fixedly installed on one of the strip-shaped slide bases 6b in the cross beam 6, and the other second linear guide rail 7 is fixedly installed on the other strip-shaped slide base 6b in the cross beam 6. The Y-axis slide base 2 is fixedly installed on the sliders of the second linear guide rails 7, and a second driving gear 10 which is meshed with the second rack 8 is synchronously rotated and sleeved on the motor shaft of the second driving motor 9.

[0096] A first rack 1d, at least one first linear guide rail 1c which are all installed along the vertical direction on the Z-axis sleeve 1, and a first driving motor 3 fixedly installed on the Y-axis slide base 2 form a sleeve driving assembly. The Y-axis slide base 2 is fixedly connected with the sliders of the first linear guide rails 1c, and a first driving gear 4 which is meshed with the first rack 1d is synchronously rotated and sleeved on the motor shaft of the first driving motor 3.

[0097] Second oil pressure buffers 39 and second force sensors 38 are provided on one side of the two cross beams 6 close to each other. The second oil pressure buffer 39 of one cross beam 6 is opposite to the second force sensor 38 of the other cross beam 6, and the second force sensor 38 of this cross beam 6 is opposite to the second oil pressure buffer 39 of the other cross beam 6. When the second oil pressure buffer 39 abuts against the corresponding second force sensor 38, the second oil pressure buffer 39 can first play a buffering role, and at the same time can also trigger the second force sensor 38 to send a stop signal, thereby avoiding the two cross beams 6 from colliding.

[0098] Please refer to Figure 1 and Figure 8, a vision detection component 26 is installed on the main beam 12b1 located at the side inlet / outlet 12d. Two waste collection bins 25 are installed below the main beam 12b1, and the vision detection component 26 is directly above the two waste collection bins 25. Among them, the vision detection component 26 is used for vision detection of the workpieces after laser cutting, and the waste collection bins 25 are used for centralized collection of waste materials.

[0099] The vision detection component 26 includes a camera base 26a fixedly installed on the main beam 12b1, a sixth rack 26c and two sixth linear guides 26b both fixedly installed on the camera base 26a along the length direction of the main beam 12b1, a long bracket 26d simultaneously installed on the sliders of the two sixth linear guides 26b, a sixth motor 26k, a seventh guide 26h and a seventh rack 26i all fixedly installed on the long bracket 26d, a camera mounting seat 26j fixedly installed on the slider of the seventh guide 26h, and a seventh motor 26e and a vision camera 26f both fixedly installed on the camera mounting seat 26j. Among them, the long bracket 26d extends in the horizontal direction perpendicular to the sixth linear guide 26b, and the seventh guide 26h and the seventh rack 26i both extend along the length direction of the long bracket 26d. The lens of the vision camera 26f faces downward. A sixth driving gear 26g meshing with the sixth rack 26c is sleeved on the motor shaft of the sixth motor 26k in a synchronously rotating manner, and a seventh driving gear 26l meshing with the seventh rack 26i is sleeved on the motor shaft of the seventh motor 26e in a synchronously rotating manner.

[0100] Therefore, by driving the sixth driving gear 26g to rotate forward and backward through the motor shaft of the sixth motor 26k, the translation of the long bracket 26d can be driven. At the same time, by driving the seventh driving gear 26l to rotate forward and backward through the motor shaft of the seventh motor 26e, the translation of the camera mounting seat 26j can be driven. Thus, the position of the vision camera 26f can be adjusted flexibly to adapt to the workpieces to be detected with large sizes and complex surface structures, and the control precision is high. Further, both the sixth motor 26e and the seventh motor 26e are preferably servo motors, which can further improve the adjustment precision of the position of the vision camera 26f.

[0101] Further, the camera base 26a is a plate-like structure with a large-area hollow to achieve a cleaning design. At the same time, at least one light bar 26m is installed on the camera base 26a, thereby providing sufficient light source for the shooting of the vision camera 26f and ensuring the quality of vision detection.

[0102] Please refer to Figures 1 - 3 and Figures 9 - 11 , positioning jigs 18 capable of moving along the width direction of the slide rail 17a under the drive of the tooling translation component 19 are installed on the slide tables 17b.

[0103] Among them, the tooling translation assembly 19 includes a tooling base 19a fixedly installed on the corresponding slide table 17b and a tooling translation module for driving the positioning tooling 18 to move along the width direction of the slide table track 17a on the tooling base 19a. At least one set of waste removal mechanism 24 for removing the waste on the upper surface of the tooling base 19a into the waste collection box 25 is synchronously connected to the positioning tooling 18.

[0104] Therefore, the slide table module of this embodiment can provide two online-adjustable degrees of freedom in the horizontal direction, and cooperate with the multiple degrees of freedom realized on the crossbeam module, so as to realize a redundant processing mode with super many 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 profiles and obtain higher processing accuracy. And when on-line visual inspection of the workpiece is required, the positioning tooling 18 moves to directly below the visual inspection component 26 along the width direction of the slide table track 17a. At the same time, the positioning tooling 18 will synchronously drive the waste removal mechanism 24 to remove the waste on the tooling base 18 into the waste collection box 25, completing two processes in one step, that is: every time the positioning tooling 18 transfers the workpiece to be detected to directly below the visual inspection component 26, each waste removal mechanism 24 also synchronously removes the waste on the tooling base 18 into the waste collection box 25, which not only greatly improves the processing efficiency, but also has a clever mechanical structure design and a high degree of integration. Especially for circular metal sheets, they can be easily pushed and roll out of the slide table by their own inertia, which not only has high efficiency and little impact on the production rhythm, while 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.

[0105] Each tooling base 19a includes a material receiving plate 19a1 fixedly installed on the corresponding slide table 17b and two guide rail mounting brackets 19a2. The two guide rail mounting brackets 19a2 are relatively installed on both sides of the material receiving plate 19a1 along the length direction of the slide table track 17a. The two guide rail mounting brackets 19a2 are preferably fixedly installed on the slide table 17b and fixedly connected to the material receiving plate 19a1, ensuring the stability and reliability of the tooling base 19a.

[0106] 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. The fourth rack 19b and the fourth linear guide rail 19c both extend along the width direction of the slide rail 17a. The positioning tooling 18 includes a driving carriage 18a and a driven carriage 18b on both sides of the 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 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.

[0107] 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.

[0108] In this embodiment, a set of waste removal mechanisms 24 for removing the waste on the upper surface of the receiving plate 19a1 to one side in the width direction of the slide rail 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 receiving plate 19a1 is better.

[0109] The upper surface of the material receiving plate 19a1 is recessed to form two material receiving grooves 19a11 respectively located below the corresponding waste removing mechanisms 24, so as to reliably collect the waste generated by laser cutting. At the same time, each waste removing mechanism 24 includes a connecting component 24a installed on the corresponding active carriage 18a or driven carriage 18b and a removing 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 removing components 24b independently removes the waste in the material receiving groove 19a11, with high reliability. Specifically, the bottom of each material receiving groove 19a11 is recessed to form a plurality of material guiding slits 19a12 that penetrate the material receiving plate 19a1 side by side in the width direction of the slide table track 17a. Each removing component 24b includes a push-pull shaft 24b1 extending in the length direction of the slide table track 17a, a material removing push block 24b2 slidably installed in the material guiding slit 19a12 one by one, and a push-pull crank 24b3 hinged to the same end of each material removing push block 24b2 one by one. One end of each push-pull crank 24b3 away from the material removing push block 24b2 is respectively hinged to the corresponding push-pull shaft 24b1. The connecting component 24a includes a push-pull plate 24a1 fixedly connected to the corresponding active carriage 18a or driven carriage 18b and a push-pull connecting rod 24a2 hinged to the corresponding push-pull plate 24a1. One end of each push-pull connecting rod 24a2 away from the push-pull plate 24a1 is respectively hinged to the corresponding push-pull shaft 24b1.

[0110] 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 connecting rod 24a2, and the push-pull shaft 24b1 then synchronously pushes and pulls the material removing push block 24b2 through each push-pull crank 24b3, so as to push the waste in each material guiding slit 19a12 to the outside of the slide table module. Since the cutting waste is usually a metal sheet (either circular or strip-shaped) generated by punching holes, and the width of the material guiding slit 19a12 is designed to be smaller than that of the metal sheet, it can ensure that the metal sheet is placed obliquely in the material guiding slit 19a12 and is easy to be pushed by the material removing push block 24b2. If the metal sheet is circular, with a slight push from the material removing push block 24b2, the circular metal sheet can roll into the waste collection box 25 under the support of the side wall of the material guiding slit 19a12 by using its own inertia.

[0111] Further, in order to make it easier to push the metal sheet out of the material guiding slit 19a12, in this embodiment, in the same material receiving groove 19a11: each material guiding slit 19a12 is arranged to incline downward from one end close to the pushing and pulling shaft 24b1 towards the other end synchronously, that is, to incline obliquely downward towards the waste collection box 25. Since each material guiding slit 19a12 is designed to incline obliquely downward towards the output end, whether it is a circular metal sheet or a strip-shaped metal sheet, the material removing push block 24b2 only needs to apply a relatively small thrust as set, and then the circular metal sheet and the strip-shaped metal sheet can smoothly slide out along the material guiding slit 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.

[0112] Further, 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 groove walls of the material guiding slit 19a12 are mirror-image arranged, and each material guiding slit 19a12 is composed of an inclined section 19a121 and a vertical section 19a122 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 groove bottom, 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 included angle with the vertical section 19a122, and thus is more easily pushed by the material removing push block 24b2.

[0113] Correspondingly, each material removing push block 24b2 includes a connecting arm 24b21 hinged to the corresponding pushing and pulling crank 24b3 and a removing block 24b22 integrally formed at one end of the corresponding connecting arm 24b21 far from the pushing and pulling crank 24b3. 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 at the lower part of the removing block 24b22. Therefore, the metal sheet generated by laser cutting will be inclinedly supported in the material guiding slit 19a12 and will not completely fit on the bottom or side wall of the material guiding slit 19a12, so that the material removing push block 24b2 can very easily push the metal sheet in the material guiding slit 19a12 and avoid the jamming problem.

[0114] Furthermore, in this embodiment, the upper part of the waste removal block 24b22 is designed to be relatively wide, so that the gap between the upper parts of adjacent waste removal blocks 24b22 is very small (usually much smaller than the diameter or width of the metal sheet), so that the waste that does not fall into the material guiding slot 19a12 can be pushed away together, ensuring the thoroughness of waste removal. In this embodiment, in order to ensure the stability of the operation of the push-pull shaft 24b1, push-pull shaft guiding slots 19a13 adapted to the corresponding push-pull shafts 24b1 are provided on both side walls of the material receiving groove 19a11, and both ends of each push-pull shaft 24b1 are slidably fitted into the corresponding push-pull shaft guiding slots 19a13, thus ensuring the synchronism of the operation of each material removal push block 24b2 and avoiding jamming problems.

[0115] The active carriage 18a includes an active carriage base 18a1 fixedly installed on the slider of the corresponding 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 installed on the active carriage base 18a1. The active carriage connecting seat 18a4 is fixedly installed at one end of the active carriage base 18a1 and is connected to the corresponding waste removal mechanism 24. The active carriage fixed mounting plate 18a2 is fixedly installed at the other end of the active carriage base 18a1. A first elongated hole 18a11 extending in 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 installed beside the active carriage connecting seat 18a4.

[0116] Similarly, the driven carriage 18b includes a driven carriage base 18b1 fixedly installed on the slider of the corresponding 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 installed on the driven carriage base 18b1. The driven carriage connecting seat 18b4 is fixedly installed at one end of the driven carriage base 18b1 and is connected to the corresponding waste removal mechanism 24. The driven carriage fixed mounting plate 18b2 is fixedly installed at the other end of the driven carriage base 18b1. A second elongated hole 18b11 extending in 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. 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, workpieces of different sizes can be adapted, and the versatility is good.

[0117] Furthermore, in the active carriage fixed mounting plate 18a2 and the driven carriage fixed mounting plate 18b2, one of them is provided with a bolt hole array composed of bolt holes distributed in an array, and the other is provided with a slot hole array composed of slot holes distributed in an array, which further improves the applicability to workpieces of different sizes.
