Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a telescopic laser plate cutting machine. Background Art

[0002] In the field of laser cutting technology, laser plate cutting machine is an important equipment widely used in plate processing. As industrial production's requirements for processing accuracy, efficiency and equipment convenience continue to increase, the structural design and performance optimization of laser plate cutting machines have become the focus of industry attention.

[0003] Traditional telescopic laser plate cutting machines are usually composed of multiple key components, including a chassis, a platform transmission mechanism, a workbench, a crossbeam, a drive mechanism, and a laser cutting assembly, etc. These components work together to achieve precise cutting of the plate. Among them, the transmission mechanism is used to drive the workbench to move forward to achieve loading or unloading of the plate, and to achieve cutting of the plate when moving backward (reciprocating movement in the Y-axis direction). The transmission mechanism generally adopts a chain transmission method, but because the chain transmission mechanism of the transmission mechanism is arranged in the square channel in the X-axis direction of the chassis, the length of the chassis in the X-axis direction is increased. The laser plate cutting machine also needs to install an outer surrounding sheet metal, which makes the width of the entire device in the X-axis direction larger. The larger X-axis length makes the device occupy too much space on the transport vehicle, and often because it exceeds the loading width limit of the vehicle, the outer sheet metal needs to be removed before loading. This process not only consumes a lot of manpower and time, but also frequent disassembly and reinstallation can easily damage the sheet metal, affecting its protective performance and service life. At the same time, it may also have a potential impact on the precision components inside the equipment, reducing the overall reliability of the equipment. In addition, after the equipment arrives at its destination, it needs to be installed and debugged again, further increasing the period and cost of putting the equipment into use.

DETAILED DESCRIPTION

[0032] The present invention provides a telescopic laser plate cutting machine. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0033] See also Figure 1 and Figure 2 The present invention provides a telescopic laser plate cutting machine, comprising a base frame 10, a crossbeam 20 slidably arranged on the base frame 10, a first driving mechanism 30 for driving the crossbeam 20 to move along the Y-axis direction, an X-axis slide 40 slidably arranged on the crossbeam 20, a second driving mechanism 50 for driving the X-axis slide 40 to move along the X-axis direction, a Z-axis slide 60 slidably arranged on the X-axis slide 40, a third driving mechanism 70 for driving the Z-axis slide 60 to move along the Z-axis direction, a laser cutting assembly 90 arranged on the Z-axis slide 60, a platform driving mechanism 80 arranged on the base frame 10, and a workbench 3; the platform driving mechanism 80 is used to drive the workbench 3 to move along the Y-axis direction; the platform driving mechanism 80 is connected to the workbench 3 through a chain traction mechanism 1 located on both sides of the workbench 3 in the X-axis direction, please refer to Figure 3-Figure 5 The chain traction mechanism 1 includes a mounting seat 11 fixedly connected to the square through-hole of the base frame 10, two pressure strips 12 fixedly connected to the mounting seat 11 and arranged up and down, a tensioning seat 13 slidably arranged between the two pressure strips 12, a driven sprocket 14 rotatably connected to the tensioning seat 13, a driving sprocket 15 connected to the driven sprocket 14 through a chain 16, and a tensioning screw 17 threadedly connected to the mounting seat 11; the tail of the tensioning screw 17 is used to abut against the side wall of the tensioning seat 13, and the head of the tensioning screw 17 faces the driven sprocket 14; the driving sprocket 15 is connected to the platform driving mechanism 80 through a transmission shaft 81; the chain 16 is fixedly connected to the side wall of the workbench 3 through a chain buckle 19.

[0034] In actual application, the platform driving mechanism 80 operates, and the transmission shaft 81 provides a power source for the operation of the chain traction mechanism 1, that is, the transmission shaft 81 drives the driving sprocket 15 to rotate, and the driving sprocket 15 drives the chain 16 and the driven sprocket 14 to rotate. Since the workbench 3 is fixedly connected to the chain buckle 19, the workbench 3 can follow the chain 16 to move along the width direction (Y-axis direction / front and rear direction) of the chassis 10, meeting the requirements of loading and unloading, and laser cutting of the plates placed on the workbench 3. Therefore, the telescopic laser plate cutting machine can be enclosed in the outer surrounding sheet metal, and when loading or unloading is required, the workbench 3 is moved out of the outer surrounding sheet metal to achieve safe operation.

[0035] The chain traction mechanism 1 can also adjust the tension of the chain 16. By twisting the tension screw 17 in the forward / reverse direction, the tension seat 13 slides between the pressure strips 12 under the top pulling action of the tail of the tension screw 17, and the position of the tension seat 13 relative to the Y-axis direction / front-back direction of the mounting seat 11 can be changed, so that the spacing between the driven sprocket 14 and the driving sprocket 15 can be changed, so as to achieve the tension of the chain 16 wound between the driven sprocket 14 and the driving sprocket 15. That is, during the use of the equipment, when it is found that the tension of the chain 16 changes due to wear or other reasons, the operator can simply rotate the tension screw 17 to adjust it, without complicated tools or a lot of disassembly work, reducing the maintenance difficulty and cost of the equipment.

[0036] In addition, the chain traction mechanism 1 is arranged on the inner wall of the square passage of the base frame 10, which rationally utilizes the space of the base frame 10, contributes to the compactness of the structure of the entire laser cutting machine, and reduces the space occupied by the equipment in the X-axis direction compared to the prior art, so that the equipment does not need to remove the outer sheet metal before loading.

[0037] Specifically, the first driving mechanism 30 and the second driving mechanism 50 can be driven by motors, gears, and racks; the third driving mechanism 70 can be driven by cylinders. The above driving methods are existing technologies and will not be described in detail.

[0038] Specifically, the platform driving mechanism 80 can be driven by a motor, a reducer, and a coupling. The above driving method is a prior art and will not be described in detail.

[0039] See also Figure 4In some embodiments, the mounting base 11 includes a mounting base 111 whose lower surface is fixed to the base frame 10, and a tensioning adjustment block 112 arranged on the side wall of the mounting base 111; a waist-shaped hole 1111 is provided on the mounting base 111, and the extension direction of the waist-shaped hole 1111 is consistent with the extension direction of the chain 16; the tensioning seat 13 is movably arranged in the waist-shaped hole 1111; the tensioning adjustment block 112 is threadedly connected with the tensioning screw 17. Specifically, the mounting base 111 is fixed to the upper surface of the base frame 10 and is "L"-shaped. The tensioning adjustment block 112 is located on the outer side of the mounting base 111, so that the staff can adjust the tensioning screw 17 on the tensioning adjustment block 112 from the outside. The setting of the waist-shaped hole 1111 can provide avoidance for the movement of the tensioning seat 13.

[0040] See also Figure 4 In some embodiments, a loose nut 18 is threadedly connected to the rod body of the loosening screw 17, and the side wall of the loosening nut 18 is used to abut against the side wall of the tensioning adjustment block 112. After adjusting the position of the loosening screw 17, the loosening nut 18 is used to reinforce it to further limit the movement of the tensioning seat 13 in the front-to-back direction, ensuring that the chain traction mechanism 1 will not be displaced during the operation of the equipment.

[0041] See also Figure 4 In some embodiments, the tension seat 13 includes a tension base plate 131 and a central shaft 132 fixed to the tension base plate 131; the central shaft 132 passes through the middle of the tension base plate 131, and the inner end of the central shaft 132 is rotatably connected to the driven sprocket 14; the outer end of the central shaft 132 passes through the waist-shaped hole 1111; the side wall of the central shaft 132 abuts against the tail of the tension screw 17. A through hole is provided in the middle of the tension base plate 131 for the central shaft 132 to pass through, and the two are fixed by welding. The outer end of the central shaft 132 can reciprocate in the waist-shaped hole 1111.

[0042] See also Figure 4 In some embodiments, a vertical plane 1321 is provided at the outer end of the central shaft 132, and the vertical plane 1321 is used to contact the tail of the tension screw 17. The outer peripheral surface of the shaft is generally an arc surface, and the vertical plane 1321 formed can increase the contact area between the tail of the tension screw 17 and the central shaft 132.

[0043] See also Figure 5In some embodiments, the cross-section of the tensioning bottom plate 131 is an isosceles trapezoid, and the side walls of the two pressure strips 12 facing each other are both arranged as inclined surfaces, and the two inclined surfaces are respectively in contact with the upper surface or the lower surface of the tensioning bottom plate 131. By limiting the shapes of the tensioning bottom plate 131 and the pressure strip 12, the tensioning bottom plate 131 can be limited in the upper and lower directions, which is a clever design.

[0044] See also Figure 1 and Figure 2 In some embodiments, the inner side wall of the base frame 10 is provided with an embedding opening 101 having the same number as the mounting seats 11, and the mounting seats 11 are fixedly mounted in the corresponding embedding openings 101. The embedded openings 101 are provided to provide installation space for the mounting seats 11, which can further shorten the length of the base frame 10 in the X-axis direction.

[0045] See also Figure 1 and Figure 2 In some embodiments, the outer wall of the base frame 10 is provided with inspection openings 102 that are the same in number as the mounting seats 11. Since the mounting seats 11 are embedded in the square tube in this embodiment, the inspection openings 102 are provided on the other side of the square tube, so that the staff can adjust the tightness of the chain 16 when the laser cutting machine is surrounded by sheet metal.

[0046] See also Figure 1 and Figure 2In some embodiments, an auxiliary bracket 2 is further provided on the side wall of the cross beam 20, and the auxiliary bracket 2 includes a vertical rod 21 extending vertically, and a cross rod 22 fixedly connected to the upper end of the vertical rod 21 and extending laterally; the lower end of the vertical rod 21 is fixedly connected to the side wall of the cross beam 20, the cross rod 22 is located above the cross beam 20, and the extension direction of the cross rod 22 is consistent with the extension direction of the cross beam 20; the free end of the cross rod 22 is used to be fixedly connected to the end of the X-axis drag chain. The frame body is composed of the vertical rod 21 and the cross rod 22. The vertical rod 21 extends vertically to provide vertical support for the entire auxiliary bracket 2, and its lower end is firmly connected to the side wall of the cross beam 20. The crossbar 22 is fixedly connected to the upper end of the vertical bar 21 and extends laterally. Its position is above the crossbeam 20. This design cleverly utilizes the space above the crossbeam 20 to place the X-axis drag chain, which changes the problem that the traditional drag chain is set close to the outside, resulting in an increase in the width of the Y-axis of the cutting machine, and further reduces the overall volume of the laser cutting machine. In addition, the extension direction of the crossbar 22 is consistent with the crossbeam 20, which allows the X-axis drag chain to be reasonably arranged along the direction of the crossbeam 20 after installation. The free end of the crossbar 22 is a key part that is fixed to the end of the X-axis drag chain. Through this fixing method, the X-axis drag chain is stably placed above the crossbeam 20, avoiding the X-axis drag chain from extending outward to occupy additional width space. Moreover, this fixing method can ensure that the movement trajectory of the X-axis drag chain is more stable when it follows the movement of the X-axis, reducing the interference to the cutting work caused by the shaking or deviation of the X-axis drag chain.

[0047] See also Figure 1 and Figure 2 In some embodiments, the auxiliary bracket 2 further includes a plurality of support rods 23 arranged at equal intervals, the lower ends of the plurality of support rods 23 are used to be fixedly connected to the rear side wall of the cross beam 20, and the upper ends of the support rods 23 are used to be fixedly connected to the lower surface of the cross bar 22. The support rods 23 added to the auxiliary bracket 2 for installing the X-axis drag chain are designed to be fixedly connected to the outer side wall of the cross beam 20 at the lower end, and to be fixedly connected to the lower surface of the cross bar 22 at the upper end. This design further improves the structure of the auxiliary bracket 2 and enhances the stability of the entire bracket from a mechanical point of view. Moreover, during the operation of the laser cutting machine, the X-axis drag chain will generate forces in various directions when moving, including its own gravity, inertial force during movement, and additional forces that may be generated by external interference. The addition of the support rod 23, together with the vertical rod 21, provides a more stable support for the cross bar 22. It can share part of the force borne by the vertical rod 21, especially when dealing with vertical pressure and horizontal shear force. Through multi-point support, the cross bar 22 is less likely to deform or displace under complex force conditions, thereby ensuring the stability of the installation position of the X-axis drag chain.

[0048] See also Figure 3 and Figure 5In some embodiments, the workbench 3 includes a workbench body, a first-stage moving frame 31 fixed to the lower surface of the workbench body, a second-stage moving frame 32 arranged below the first-stage moving frame 31, a first-stage guide rail assembly 33 arranged inside the first-stage moving frame 31, a second-stage guide rail assembly 34 arranged inside the second-stage moving frame 32, an upper moving block 35 arranged on the side wall of the first-stage moving frame 31, and a first lower moving block 36 and a second lower moving block 37 arranged on the side wall of the second-stage moving frame 32; the first lower moving block 36 and the second lower moving block 37 are extended along the Y-axis direction, and the first lower moving block 36 is located in front of the second lower moving block 37; the upper moving block 35 is located between the two first lower moving blocks 36 and the second lower moving block 37, and the front side wall of the upper moving block 35 is used to abut against the rear side wall of the first lower moving block 36, and the rear side wall of the upper moving block 35 is used to abut against the front side wall of the second lower moving block 37; the chain buckle 19 is fixedly connected to the side wall of the first section moving frame 31; the first section moving frame 31 and the second section moving frame 32 are slidably connected by a two-section guide rail assembly 34; the first section moving frame 31 and the workbench body are slidably connected by a first section guide rail assembly 33.

[0049] When the laser plate cutting machine needs to load or unload materials, the chain traction mechanism 1 enables the workbench 3 to move forward in two sections; conversely, when the plate needs to be laser cut, the chain traction mechanism 1 also enables the workbench 3 to be reset (i.e., the first section moving frame 31 and the second section moving frame 32 are both located directly below the workbench 3). Its working principle is as follows: the upper moving block 35 is used to move forward, and after abutting against the rear side wall of the first lower moving block 36, the first lower moving block 36 is continuously pushed forward to realize the forward movement of the first section moving frame 31 and the second section moving frame 32, i.e., realize the two-section forward movement; similarly, the upper moving block 35 is used to move backward, and after abutting against the front side wall of the second lower moving block 37, the second lower moving block 37 is continuously pushed backward to realize the backward movement of the first section moving frame 31 and the second section moving frame 32, i.e., realize the two-section backward movement. The first-stage guide rail assembly 33 and the second-stage guide rail assembly 34 are used to provide guidance for the movement of the first-stage moving frame 31 and the second-stage moving frame 32, limiting the first-stage moving frame 31 and the second-stage moving frame 32 to reciprocate only in the Y-axis direction.

[0050] Specifically, the first section guide rail assembly 33 and the second section guide rail assembly 34 can be composed of guide rails, sliders, support beams, limit blocks and other components, so that the support beams can reciprocate along the Y-axis direction under the guidance of the guide rails. The above structure is the existing technology and will not be repeated here.

[0051] See also Figure 1 and Figure 2In some embodiments, a limiting mechanism 4 for limiting the position of the workbench 3 is also included, see Figure 6-Figure 7 The limiting mechanism 4 includes a positioning hook 41 arranged on the workbench 3, a fixed seat 42 arranged on the base frame 10, a driving member 43 arranged on the fixed seat 42, a follower seat 44 fixedly connected to the output end of the driving member 43, and a positioning member 45 arranged on the follower seat 44; the driving member 43 is used to drive the follower seat 44 to rise, so that the positioning member 45 moves in a direction away from the positioning hook 41; the driving member 43 is used to drive the follower seat 44 to descend, so that the positioning member 45 moves in a direction close to the positioning hook 41.

[0052] In order to avoid the work, the limit mechanism 4 is arranged at the rear of the workbench 3. When the workbench 3 needs to cut the plate, the workbench 3 moves toward the direction close to the limit mechanism 4 (rear); when the plate is cut and the workbench 3 needs to unload the plate, the workbench 3 moves away from the limit mechanism 4 (front). Figure 2 and Figure 3 When the workbench 3 moves toward the direction (rearward) of the limiting mechanism 4, the output end of the driving member 43 drives the follower seat 44 and the positioning member 45 disposed on the follower seat 44 to move downward until the positioning member 45 is located in the positioning hook 41, and the positioning hook 41 and the positioning member 45 cooperate to "hook" the workbench 3, thereby achieving accurate positioning of the workbench 3. When the workbench 3 needs to be released from the limit after cutting is completed, the output end of the driving member 43 drives the follower seat 44 and the positioning member 45 disposed on the follower seat 44 to move upward, so that the positioning hook 41 and the positioning member 45 are gradually separated. The above-mentioned limiting mechanism 4 can realize the positioning of the workbench 3 and release the positioning of the workbench 3 through the cooperation of the positioning hook 41 and the positioning member 455.

[0053] See also Figure 6 In some embodiments, the opening of the positioning hook 41 faces upward, and the spacing of the opening of the positioning hook 41 gradually increases from bottom to top. That is, in this embodiment, the positioning member 45 is located above the positioning hook 41, and under the action of the driving member 43, the positioning member 45 gradually moves from top to bottom to the bottom of the positioning hook 41. By limiting the spacing of the openings, an inclined plane guide is provided for the movement of the positioning member 45, so that the positioning member 45 can move smoothly.

[0054] See also Figure 6In some embodiments, the positioning hook 41 includes a mounting portion 411 for fixing to the rear side wall of the workbench 3, a connecting portion 412 fixed to the mounting portion 411, and an inclined plate 413 fixed to the connecting portion 412, and the opening of the positioning hook 41 is formed by the connecting portion 412 and the inclined plate 413. In this embodiment, the positioning hook 41 is formed by welding the mounting portion 411, the connecting portion 412, and the inclined plate 413, and the positioning hook 41 is divided into three parts, which makes it easy to form a "V"-shaped special-shaped opening structure on the positioning hook 41.

[0055] See also Figure 6 In some embodiments, the positioning member 45 is a first roller, which can rotate relative to the follower seat 44, and the first roller is used to roll with the inner wall of the inclined plate 413. When the workbench 3 gradually moves toward the direction of the limiting mechanism 4, the driving member 43 synchronously drives the follower seat 44 and the first roller to descend. While the first roller descends, it gradually contacts the inner wall of the inclined plate 413 and rolls downward. Under the guidance of the inclined surface of the inclined plate 413, it gradually rolls to the bottom of the positioning hook 41. Conversely, when the workbench 3 gradually moves in the direction away from the limiting mechanism 4, the first roller also contacts the inner wall of the inclined plate 413 and rolls upward. The above arrangement can not only realize the follow-up limit, but also reduce the friction when the positioning member 45 contacts the inclined plate 413.

[0056] See also Figure 6 and Figure 7 In some embodiments, the driving member 43 is a cylinder, the cylinder body of the cylinder is fixedly connected to the fixing seat 42, the output end of the cylinder faces upward and passes through the fixing seat 42, and is fixedly connected to the follower seat 44. In this embodiment, the output end of the cylinder has only a fully extended or fully contracted state, and the structure is simple. When the output end of the cylinder is in a fully extended state, the follower seat 44 and the positioning member 45 are located at the highest point; when the output end of the cylinder is in a fully contracted state, the follower seat 44 and the positioning member 45 are located at the lowest point.

[0057] See also Figure 6 and Figure 7 In some embodiments, the follower seat 44 includes a horizontal plate 441 fixedly connected to the output end of the cylinder, and a vertical plate 442 fixedly connected to the horizontal plate 441, and the horizontal plate 441 and the vertical plate 442 are perpendicular to each other; the positioning member 45 is arranged on the outer side of the vertical plate 442. The follower seat 44 is composed of a horizontal plate 441 and a vertical plate 442 fixedly connected to each other, which is conducive to the formation of a special-shaped follower seat 44. Specifically, the vertical plate 442 is provided with a notch 4423 in the direction toward the workbench 3. When the plate is laser cut, the laser cutting assembly 90 will move to the vicinity of the limiting mechanism 4, and the provision of the notch 4423 can increase the safety distance between the vertical plate 442 and the laser cutting assembly 90.
