Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting machines, and in particular to a laser cutting machine with a function of preventing cutting materials from deviating. Background Art

[0002] With the continuous development of industrial manufacturing, laser cutting technology has been widely used in the processing of various materials such as metals, plastics, and ceramics. Laser cutting machines use the high temperature and high energy of laser beams to cut materials. They have the advantages of high cutting accuracy, small thermal impact, fast cutting speed, and small workpiece deformation, making them an indispensable equipment in modern manufacturing. However, in actual application, especially in high-precision cutting, the fixation and positioning of materials are still the key factors affecting the quality and efficiency of laser cutting.

[0003] Most laser cutting machines on the market currently use manual or simple mechanical clamps to fix materials, but this method has certain limitations. First, manual fixing of materials is not only inefficient, but also easily causes the position of the materials to shift, resulting in reduced cutting accuracy. Secondly, although traditional mechanical clamps can fix materials, their clamping force is not uniform enough, and it is easy for materials to loosen or shift during the cutting process, especially when dealing with thin, light or irregularly shaped materials. The shift phenomenon is more serious. What's more serious is that the waste disposal system of some laser cutting machines is not perfect, and the waste cannot be cleaned up in time, which will have an adverse effect on the cutting process and may even cause equipment damage. Summary of the invention

[0004] In view of the defects existing in the above prior art, the present invention provides a laser cutting machine with a function of preventing the cutting material from deviating, thereby solving the problem that the existing method of fixing materials manually or with simple mechanical clamps is inefficient and may cause material position deviation.

[0005] The objective of the present invention is achieved through the following technical scheme: a laser cutting machine with a function of preventing the cutting material from deviating, comprising a laser cutting machine frame, a workbench for supporting the material is installed on the top of the laser cutting machine frame, and is characterized in that: strip-shaped through holes are opened on both sides of the workbench, and a plurality of equidistant supporting racks are plugged and connected in the workbench, a laser generator that can move horizontally, longitudinally and vertically along the laser cutting machine frame is arranged on the top of the laser cutting machine frame, and the laser generator is moved by a guide rail and a driving device, and an automatic moving, positioning and fixing material device is arranged in the two strip-shaped through holes, and a waste trolley is arranged at the bottom of the laser cutting machine frame.

[0006] Furthermore, the automatic moving, positioning and fixing material device includes two first racks, which are respectively installed in the two strip-shaped through holes, and first linear guides are installed on both side walls of the workbench. Two moving plates are installed on one side of the slider of the first linear guide, and a first servo motor is installed on one side of the moving plate. A first gear is installed on the output end of the first servo motor, and the first gear is meshed with the first rack. A side plate and a second rack are connected between the two opposite moving plates, and a second linear guide is installed on one side of the side plate. Two frame frames are installed on one side of the slider of the second linear guide, and a second servo motor is installed on the inner side of the frame frame. The output end of the second servo motor is connected to a second gear, and the second gear is meshed with the second rack. A first cylinder is installed in the frame frame, and the output end of the first cylinder passes through the top of the frame frame and is connected to a C-shaped mounting block, and a second cylinder is installed on the top of the C-shaped mounting block, and the output end of the second cylinder passes through the top of the C-shaped mounting block and is connected to a pressure plate.

[0007] Furthermore, the mobile laser generator comprises a laser emitting head, a protective cover is installed outside the laser emitting head, and the protective cover is made of a transparent high-temperature resistant material.

[0008] Furthermore, a rubber pad is provided at the bottom of the pressing plate, and the surface of the rubber pad has anti-slip textures for increasing the friction with the material.

[0009] Furthermore, both the first servo motor and the second servo motor are electrically connected to encoders.

[0010] Furthermore, the support rack is made of high-strength alloy steel, and the surface is quenched.

[0011] In summary, compared with the prior art, the present invention has the following advantages:

[0012] 1. The present invention uses a precise rack, servo motor and cylinder system to automatically position and fix the material accurately, avoiding the material offset or inaccurate position in traditional cutting machines, ensuring high cutting accuracy. It effectively improves the cutting quality and reduces poor cutting and waste caused by material offset.

[0013] 2. The present invention adopts multiple pressing plates for flexible clamping, and provides uniform pressure through adjustable pressing plates and rubber pads (with anti-slip patterns), ensuring that the material is stably fixed, avoiding the problem of loosening of the material due to insufficient single clamping point. This design keeps the material fixed during the entire cutting process, reducing damage to the material during the clamping process.

[0014] 3. The present invention ensures the accuracy of positioning and movement by adopting a closed-loop control system of the first and second servo motors and an encoder. The encoder provides real-time feedback of the position, ensuring the precise operation of the pressure plate and other components throughout the process, effectively preventing positioning errors and inconsistent power transmission, and significantly improving the operating accuracy and stability of the equipment.

[0015] 4. The present invention realizes a high degree of automation through the automatic moving positioning and fixing material device, reduces manual intervention, and improves the overall work efficiency. With the precise positioning and stable clamping of the material, the laser cutting process is smoother, thereby improving the cutting speed and work efficiency of the production line.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further specifically described below through specific embodiments, but the present invention is not limited to these embodiments.

[0024] Combination Figures 1 to 6As shown, a laser cutting machine with a function of preventing the cutting material from deviating comprises a laser cutting machine frame 1, a workbench 2 for supporting the material is installed on the top of the laser cutting machine frame 1, and is characterized in that: strip-shaped through holes 201 are opened on both sides of the workbench 2, and a plurality of equidistant supporting racks 202 are plugged and connected in the workbench 2, a laser generator 3 which can move horizontally, longitudinally and vertically along the laser cutting machine frame 1 is arranged on the top of the laser cutting machine frame 1, and the laser generator 3 is moved by guide rails and a driving device, and an automatic moving, positioning and fixing material device 4 is arranged in the two strip-shaped through holes 201, and a waste trolley 5 is arranged at the bottom of the laser cutting machine frame 1.

[0025] Combination Figure 4 , Figure 6As shown, the automatic moving positioning and fixing material device 4 includes two first racks 401, and the two first racks 401 are respectively installed in the two bar-shaped through holes 201. The two side walls of the workbench 2 are both installed with first linear guide rails 402, and two moving plates 403 are installed on one side of the slider of the first linear guide rail 402. A first servo motor 404 is installed on one side of the moving plate 403. A first gear 405 is installed on the output end of the first servo motor 404. The first gear 405 is meshed and connected with the first rack 401. A side plate 406 and a second rack 407 are connected between the two opposite moving plates 403. A second linear guide rail 408 is installed on one side of the side plate 406. Two frame frames 409 are installed on one side of the slider of the second linear guide rail 408. The inner side of the frame frame 409 A second servo motor 410 is installed, and the output end of the second servo motor 410 is connected to a second gear 411, and the second gear 411 is meshed with the second rack 407. A first cylinder 412 is installed in the frame 409, and the output end of the first cylinder 412 passes through the top of the frame 409 and is connected to a C-shaped mounting block 413, and a second cylinder 414 is installed on the top of the C-shaped mounting block 413, and the output end of the second cylinder 414 passes through the top of the C-shaped mounting block 413 and is connected to a pressure plate 415; the first servo motor 404 drives the first gear 405, and through the meshing transmission of the first gear 405 and the first rack 401, the movable plate 403 is driven to move horizontally on the first linear guide rail 402, so that the side plate 406 and the second rack 407 reach the horizontal coordinates of the preset workstation. Subsequently, the second servo motor 410 drives the second gear 411, which, in conjunction with the longitudinal transmission of the second rack 407, controls the frame 409 to slide longitudinally on the second linear guide rail 408, and finally positions the pressing plate 415 below the area where the material needs to be fixed. The first cylinder 412 drives the C-type mounting block 413 to rise vertically, so that the C-type mounting block 413 passes between adjacent supporting racks 202, so that the pressing plate 415 rises above the material, and then the second servo motor 410 drives the second gear 411 again, and the second rack 407 is longitudinally transmitted to control the frame frame 409 to slide longitudinally on the second linear guide 408, and the C-type mounting block 413 is fine-tuned to make the edge of the material located inside the C-type mounting block 413 and below the pressing plate 415; the second cylinder 414 further applies vertical pressure, and the rubber pad with anti-slip texture on the bottom of the pressing plate 415 generates high friction. A total of four pressing plates 415 press the four corners of the material respectively, realizing multi-point flexible clamping, ensuring that the pressing plate 415 can press materials of different sizes and complex shapes, and providing a high degree of flexibility and stability.

[0026] Combination Figure 3 , Figure 5As shown, the mobile laser generator 3 includes a laser emitting head 31, and a protective cover 32 is installed outside the laser emitting head 31. The protective cover 32 is made of a transparent and high-temperature resistant material. The transparent and high-temperature resistant protective cover 32 effectively protects the laser emitting head 31 from being contaminated by external substances and damaged by high temperature, thereby extending the service life of the laser equipment and ensuring the safety of the operator.

[0027] A rubber pad is provided at the bottom of the pressing plate 415. The surface of the rubber pad has anti-slip patterns for increasing the friction with the material, which can effectively increase the friction with the material surface, thereby improving the stability of material fixation and preventing the material from sliding or shifting during the cutting process.

[0028] The first servo motor 404 and the second servo motor 410 are both electrically connected to encoders, which ensures accurate control of the servo motors, can provide real-time feedback on positions and states, reduce errors, improve positioning accuracy, and provide strong support for the positioning of the automatic mobile positioning and fixing material device 4.

[0029] The support rack 202 is made of high-strength alloy steel, and its surface is quenched, which improves the strength and wear resistance of the support rack 202, making it able to withstand large loads and high temperature environments and adapt to long-term high-load work.

[0030] Working principle: When the material to be cut is placed on the surface of the support rack 202 of the workbench 2, the automatic moving positioning and fixing device 4 starts working. The first servo motor 404 drives the first gear 405, and through the meshing transmission of the first gear 405 and the first rack 401, the moving plate 403 is driven to move horizontally on the first linear guide 402, so that the side plate 406 and the second rack 407 reach the horizontal coordinates of the preset station. Subsequently, the second servo motor 410 drives the second gear 411, combined with the longitudinal transmission of the second rack 407, to control the frame 409 to slide longitudinally on the second linear guide 408, and finally position the pressing plate 415 below the area where the material needs to be fixed. The first cylinder 412 drives the C-type mounting block 413 to rise vertically, so that the C-type mounting block 413 passes between adjacent supporting racks 202, so that the pressing plate 415 rises above the material. Therefore, when the first cylinder 412 drives the C-type mounting block 413 to reach the minimum stroke, the top of the second cylinder 414 must be located below the bottom of the supporting rack 202 to ensure that the supporting rack 202 does not contact the bottom of the supporting rack 202 when moving. The second servo motor 410 drives the second gear 411 again, combined with the longitudinal transmission of the second rack 407, the control frame 409 slides longitudinally on the second linear guide 408, and the C-type mounting block 413 is fine-tuned to make the edge of the material located inside the C-type mounting block 413 and below the pressing plate 415; the second cylinder 414 further applies vertical pressure, and cooperates with the rubber pad with anti-slip patterns on the bottom of the pressing plate 415 to generate high friction. A total of four pressing plates 415 press the four corners of the material respectively to achieve multi-point flexible clamping. Through the closed-loop control of two sets of servo motors and encoders, the pressure plate group can move along the XY plane according to the program setting, dynamically adjust the clamping position, and when the material is stable and fixed, the laser generator 3 moves along the three-dimensional guide system in the X / Y / Z axis, and the laser beam is focused on the surface of the material for precise cutting. The design of the support rack 202 not only provides dispersed support force, but also allows the debris generated by cutting to fall through the gap between the teeth, and finally be collected by the waste trolley 5 at the bottom.

[0031] The implementation of the present invention is not limited to the above-mentioned embodiments. Without departing from the spirit and scope of the present invention, ordinary technicians in this field can make various changes and improvements to the present invention in form and detail, and these are considered to fall within the protection scope of the present invention.
