Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting machines, and particularly to a laser cutting machine with multi-zone dust removal. Background Art

[0002] A laser cutting machine emits laser light from a laser, which is focused into a laser beam with a high power density through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, a high-pressure gas coaxial with the beam blows away the melted or vaporized metal. As the relative position of the beam and the workpiece moves, finally a cut is formed in the material, thus achieving the purpose of cutting.

[0003] In the field of laser cutting processing, laser cutting machines are widely used due to their advantages such as high precision and high efficiency. A large amount of metal debris is generated during the cutting process of existing laser cutting machines, and the metal debris is prone to accumulate inside the machine tool and on the cutting table board, which not only affects the cutting quality but may also cause damage to the machine tool and the cutting head. At the same time, the rotating shaft of the cutting table board is exposed to the workshop environment and is easily invaded by metal debris or oil stains, resulting in an increase in the flipping resistance or even jamming, leading to low flipping efficiency of the cutting table and seriously affecting the operation efficiency and stability of the equipment.

[0016] Compared with the prior art, the present invention provides a laser cutting machine with multi-zone dust removal, and has the following beneficial effects: 1. For the laser cutting machine with multi-zone dust removal, the centrifugal fan operates to generate negative pressure, sucking impurities inside the machine tool and outside the rotating shaft into the scraper. The scraper adsorbs impurities through the adsorption holes, and the impurities enter the collection box through the collection pipe, which can effectively perform zoned dust removal and cleaning on the impurities inside the machine tool and outside the rotating shaft, keep the inside of the machine tool clean, reduce the influence of impurities on the cutting accuracy and the service life of the equipment. By setting the adaptive lubrication structure, siphon automatic oil replenishment can be realized according to the operating conditions of the rotating shaft, effectively preventing the rotating shaft from getting stuck due to lack of lubrication, ensuring that the rotating shaft is fully lubricated and reducing wear, prolonging the service life of the equipment, and the voltage stabilizing structure can ensure stable oil injection pressure and improve the lubrication effect.

[0017] 2. The laser cutting machine with multi-zone dust removal starts the operation of the dual-axis motor through the controller. The output shaft at its right end drives the reciprocating lead screw to rotate, causing the threaded block to drive the cleaning brush to move reciprocally, cleaning the cutting slag on the surface of the cutting table. The slag falls into the aggregate box through the slag discharge port, improving the cleaning efficiency, ensuring the cleanliness of the cutting table surface, and facilitating subsequent cutting operations.

[0018] 3. The laser cutting machine with multi-zone dust removal drives the rotating disc to rotate through the output shaft at the left end of the dual-axis motor. Under the driving action of the pulley and the sliding rod that make the toothed plate swing reciprocally, the gear is driven to rotate, causing the rotating shaft to drive the cutting table to reciprocally flip while performing maintenance lubrication; the output shaft at the right end of the dual-axis motor drives the reciprocating lead screw to rotate, realizing the linkage between the flipping of the cutting table and the cleaning of the cleaning brush, achieving the cleaning of impurities inside the machine tool and outside the rotating shaft, automatic oil replenishment of the rotating shaft, and rapid cleaning of the accumulated impurities, thereby improving the cutting efficiency and cutting quality, extending the service life of the machine tool, and significantly enhancing the performance and use value of the laser cutting machine.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 8 , a laser cutting machine with multi-zone dust removal in this embodiment includes a machine tool 1, a laser cutting mechanism 2 disposed on the top of the machine tool 1 and extending into its interior, and a cutting table structure 3 disposed inside the machine tool 1. The cutting table structure 3 includes a rotating shaft 31 and a cutting table plate 32. A dust removal mechanism 4 for partitioning and dust-removing and cleaning impurities inside the machine tool 1 and outside the rotating shaft 31 is disposed outside the machine tool 1. The number of the rotating shaft 31 and the cutting table plate 32 is two groups each.

[0023] Among them, the dust removal mechanism 4 includes a collection box 41 fixedly connected to the outside of the machine tool 1, a centrifugal fan 42 rotatably installed outside the collection box 41, a connecting plate 43 arranged outside the rotating shaft 31, a contact spring 44 fixedly connected to the bottom of the connecting plate 43, a scraping plate 45 fixedly connected to the bottom of the contact spring 44, an adsorption hole 46 opened inside the scraping plate 45, a collection pipe 47 fixedly connected between the collection box 41 and the scraping plate 45, and a filter frame 48 slidably connected inside the collection box 41. The dust removal mechanism 4 effectively removes impurities inside the machine tool 1 and outside the rotating shaft 31, reduces the influence of impurities on the laser cutting optical path, the surface of the cutting table 32, and the workpiece, avoids problems such as a decrease in cutting accuracy and poor cutting surface quality caused by impurity interference, and timely cleans the impurities on the surface of the rotating shaft 31, which can prevent impurities from entering key components such as the bearing 57, reduce the occurrence of wear and jamming phenomena, extend the service life of the equipment, and reduce the equipment maintenance and replacement costs.

[0024] Specifically, the rotating shaft 31 is rotatably connected to the inside of the machine tool 1 and extends to its outside, the cutting table 32 is fixedly installed outside the rotating shaft 31, a moving port adapted to the filter frame 48 is opened inside the collection box 41, the number of the connecting plates 43, the contact springs 44, and the scraping plates 45 is two groups each, the connecting plates 43 are fixedly connected to the outside of the machine tool 1 and are located on the upper surface of the bearing 57. The scraping plate 45 abuts against the outer wall of the rotating shaft 31, a suction pipe is fixedly connected between the two scraping plates 45, the number of the adsorption holes 46 is several, and several adsorption holes 46 are arranged at equal intervals in sequence inside the scraping plate 45.

[0025] It should be noted that the laser cutting mechanism 2 includes two machine covers 21 fixedly connected to the top of the machine tool 1, a shielding cover 22 hinged to the outside of the machine tool 1, a longitudinal adjustment mechanism 23 fixedly installed on the top of the machine tool 1, a transverse adjustment mechanism 24 slidably installed on the top of the longitudinal adjustment mechanism 23, and a laser cutting machine body 25 fixedly installed at the bottom end of the transverse adjustment mechanism 24. The laser cutting machine body 25 is located above the cutting table 32.

[0026] When this embodiment is in use, by setting the dust removal mechanism 4 to specifically remove dust in two different areas inside the machine tool 1 and outside the rotating shaft 31, it can adopt targeted cleaning methods according to the generation characteristics and distribution laws of impurities in each area, effectively improving the dust removal efficiency. Since metal chips and lubricating oil mixed impurities are likely to accumulate during the rotation of the rotating shaft 31, the combination of the scraping plate 45 and the adsorption hole 46 can precisely clean these impurities, while dust and other impurities in other areas inside the machine tool 1 are collected through the overall negative pressure suction. Zoned dust removal avoids the mutual mixing and diffusion of impurities in different areas, prevents adverse effects on the cutting process and equipment caused by impurity cross-contamination, and ensures the relative cleanliness and stability of the cutting environment.

[0027] By setting the cooperation between the scraping plate 45 and the abutting spring 44, the scraping plate 45 can always closely fit the surface of the rotating shaft 31, ensuring that the impurities on the surface of the rotating shaft 31 are completely scraped off. At the same time, the strong negative pressure generated by the centrifugal fan 42 sucks the scraped impurities into the collection box 41 quickly through the adsorption holes 46 and the collection pipe 47, avoiding the secondary flying and accumulation of impurities in the equipment, and improving the efficiency and thoroughness of impurity cleaning. By starting the centrifugal fan 42 to run continuously through the controller, a stable negative pressure power is provided for the dust removal system, ensuring the continuity of the dust removal process. Even under high-intensity cutting operations, the generated impurities can be cleaned up in a timely and effective manner, ensuring that the equipment is always in good working condition.

[0028] Please refer to Figures 1 to 6 , in this embodiment, an adaptive lubrication structure 5 for inertial siphon oil replenishment during the operation of the rotating shaft 31 is provided outside the machine tool 1. The adaptive lubrication structure 5 includes an oil storage tank 51 and an installation cylinder 52 fixedly connected to the outside of the machine tool 1, a limit piece 53 fixedly installed on the inner top wall of the installation cylinder 52, a long suction pipe 54 slidably connected inside the limit piece 53, a return spring 55 arranged outside the long suction pipe 54, a driving plate 56 fixedly connected to the outside of the long suction pipe 54, an eccentric block 512 fixedly installed on the outside of the rotating shaft 31, a bearing 57 fixedly installed on the inner wall of the machine tool 1, an oil distribution ring 58 fixedly installed inside the bearing 57, an oil injection hole 59 opened inside the oil distribution ring 58, a guide oil pipe 510 fixedly communicating between the installation cylinder 52 and the oil distribution ring 58, and a pressure stabilizing structure arranged on the upper surface of the oil storage tank 51 and extending into its interior.

[0029] Among them, the pressure stabilizing structure includes a butting column 513 slidably connected to the upper surface of the oil storage tank 51 and extending into its interior, a baffle plate 514 fixedly connected to the top of the butting column 513, a pressure spring 516 fixedly installed between the baffle plate 514 and the oil storage tank 51, and a pressing plate 515 fixedly connected to the bottom end of the butting column 513. The pressure spring 516 is connected around the outside of the butting column 513. Through the coordinated action of the pressure spring 516, the butting column 513, the baffle plate 514 and the pressing plate 515, the pressure in the oil storage tank 51 can be adjusted in real time to compensate for the pressure fluctuations caused by the consumption of lubricating oil or changes in the external environment. Whether it is due to a large consumption of lubricating oil resulting in a decrease in the liquid level or a change in pressure caused by a change in the external temperature, the pressure stabilizing structure can keep the pressure in the oil storage tank 51 relatively stable, ensuring that the lubricating oil can smoothly enter the installation cylinder 52 through the delivery pipe 517 to achieve stable oil supply. The stable oil supply pressure can avoid problems such as poor lubricating oil delivery and cavitation caused by insufficient pressure, ensure that the entire lubrication system is always in good working condition, and improve the reliability and stability of the equipment.

[0030] Specifically, an oil injection pipe is fixedly connected to the outside of the oil storage tank 51. A delivery pipe 517 is fixedly connected between the oil storage tank 51 and the mounting cylinder 52. A one-way valve is fixedly installed inside the delivery pipe 517.

[0031] It should be noted that the long suction pipe 54 is reciprocally slidably connected to the inside of the mounting cylinder 52 through an eccentric block 512. A guide shaft 511 is fixedly connected to the top of the mounting cylinder 52. A guide hole adapted to the guide shaft 511 is formed inside the drive plate 56. The drive plate 56 is slidably connected to the outside of the guide shaft 511 through the guide hole.

[0032] When in use in this embodiment, when the rotating shaft 31 rotates, the eccentric block 512 makes a circular motion along with the rotating shaft 31. Due to its eccentric characteristic, a periodic inertial force will be generated. Under the action of the inertial force of the eccentric block 512, the drive plate 56 drives the long suction pipe 54 to reciprocally slide inside the mounting cylinder 52. When the long suction pipe 54 slides away from the oil storage tank 51, the pressure inside the mounting cylinder 52 decreases, forming a negative pressure. At this time, the one-way valve inside the delivery pipe 517 opens to allow the lubricating oil to flow from the oil storage tank 51 to the mounting cylinder 52. Under the action of the pressure difference, the lubricating oil in the oil storage tank 51 is sucked into the mounting cylinder 52 through the delivery pipe 517. When the long suction pipe 54 slides towards the oil storage tank 51, the pressure inside the mounting cylinder 52 increases, and the one-way valve closes to prevent the lubricating oil from flowing back into the oil storage tank 51. The lubricating oil inside the mounting cylinder 52 is delivered to the oil distribution ring 58 through the oil guide pipe 510. After the lubricating oil enters the oil distribution ring 58, it is evenly distributed to the surfaces of the components that need to be lubricated, such as the rotating shaft 31 and the bearing 57, to achieve the lubrication effect, realize automatic oil replenishment, without manual intervention, and improve the stability and reliability of the equipment operation.

[0033] Please refer to Figure 7 , in this embodiment, a linkage mechanism 7 extending to the inside is provided outside the machine tool 1 for synchronously driving the cutting table structure 3 and the cleaning structure 6. The cleaning structure 6 includes a reciprocating lead screw 61 rotatably connected to the inside of the machine tool 1, a threaded block 62 threadedly connected to the outside of the reciprocating lead screw 61, a support plate 63 fixedly connected to the top of the threaded block 62, an elastic telescopic rod 64 fixedly installed on the top of the support plate 63, a connection seat 65 fixedly connected to the top of the elastic telescopic rod 64, and a cleaning brush 66 fixedly connected to the top of the connection seat 65.

[0034] Among them, a limiting rod 67 is fixedly connected inside the machine tool 1, a threaded block 62 is slidably connected to the outside of the limiting rod 67, a cleaning brush 66 abuts against the outside of the cutting table plate 32, a protective cover adapted to the reciprocating lead screw 61 is fixedly connected inside the machine tool 1, an activity port adapted to the support plate 63 is opened inside the protective cover, a partition plate 8 is fixedly connected inside the machine tool 1, a collecting box 9 is slidably connected to the bottom wall of the partition plate 8 inside the machine tool 1, a slag discharge port is opened inside the partition plate 8, and the collecting box 9 is located below the slag discharge port.

[0035] When this embodiment is in use, driven by the linkage mechanism 7, the reciprocating lead screw 61 starts to rotate. By using the rotation of the reciprocating lead screw 61 to drive the threaded block 62 to perform a reciprocating linear motion, and then driving the cleaning brush 66 to reciprocate on the surface of the cutting table plate 32 through the support plate 63, the elastic telescopic rod 64, and the connecting seat 65, the cutting slag on the cutting table plate 32 is cleaned into the collecting box 9, realizing the centralized collection of the slag.

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 , in this embodiment, a linkage mechanism 7 for synchronously driving the cutting table structure 3 to reciprocally flip and for cleaning the cutting table plate 32 is provided outside the machine tool 1 and extends into its interior. The linkage mechanism 7 includes a double-shaft motor 71 fixedly installed inside the machine tool 1, a fixed plate 72 fixedly connected to the outside of the machine tool 1, a rotating disk 73 rotatably connected to the left output shaft of the double-shaft motor 71, a pulley 74 rotatably installed outside the rotating disk 73, a sliding rod 75 slidably connected to the outside of the pulley 74, a toothed plate 76 hinged to the top of the sliding rod 75, and a gear 77 fixedly installed at the left end of the rotating shaft 31. The reciprocating lead screw 61 is fixedly installed on the right output shaft of the double-shaft motor 71.

[0037] Among them, the rotating disk 73 is rotatably connected to the outside of the fixed plate 72. One end of the sliding rod 75 away from the toothed plate 76 is hinged to the outside of the fixed plate 72 through a pin shaft. The outer diameter of the pulley 74 is adapted to the inner diameter of the sliding rod 75. The sliding rod 75 and the toothed plate 76 are reciprocally swing-connected to the outside of the rotating disk 73 through the pulley 74. The toothed plate 76 and the gear 77 are meshed with each other. Connecting ears 78 are fixedly connected to both the front and rear sides of the machine tool 1, and a limiting column 79 is fixedly connected between the two connecting ears 78. The toothed plate 76 is slidably connected to the outside of the limiting column 79.

[0038] In the use of this embodiment, by using the two output shafts of the biaxial motor 71 to drive the cutting table structure 3 and the cleaning structure 6 respectively, the synchronous movement of the two is realized. Through the cooperation of the rotating disc 73, the pulley 74, the sliding rod 75, the toothed plate 76 and the gear 77, the rotational motion of the left output shaft of the biaxial motor 71 is converted into the reciprocating linear motion of the toothed plate 76, thereby driving the rotating shaft 31 to reciprocally flip; at the same time, the right output shaft of the biaxial motor 71 directly drives the reciprocating lead screw 61 to rotate, realizing the cleaning of the cutting table plate 32 by the cleaning structure 6. At the same time, the rotating shaft 31 inertia-drives the adaptive lubrication structure 5, and through the linkage of the eccentric block 512 and the long suction pipe 54, the lubricating oil is supplied on demand to adapt to the lubrication requirements under different working conditions.

[0039] The working principle of the above embodiment is as follows: In use, the longitudinal adjustment mechanism 23 and the transverse adjustment mechanism 24 are started by the controller to cooperate and drive the laser cutting machine body 25 to a specified position above the cutting table plate 32. The laser cutting machine body 25 emits a laser beam to cut the workpiece placed on the cutting table plate 32. When the cutting table plate 32 is flipped and cleaned, the biaxial motor 71 is started to work by the controller. Its left output shaft drives the rotating shaft 31 to reciprocally flip through the transmission of the rotating disc 73, the pulley 74, the sliding rod 75, the toothed plate 76 and the gear 77, realizing the angle adjustment of the cutting table plate 32. The right output shaft of the biaxial motor 71 directly drives the reciprocating lead screw 61, and the threaded block 62 horizontally reciprocates under the constraint of the limiting rod 67, driving the cleaning brush 66 to remove the slag on the surface of the cutting table plate 32, and the slag falls into the aggregate box 9 through the slag discharge port. When the machine tool 1 is partitioned and dust-removed, a negative pressure is generated by the operation of the centrifugal fan 42, and the impurities inside the machine tool 1 and outside the rotating shaft 31 are sucked into the scraper 45. The scraper 45 adsorbs the impurities through the adsorption holes 46, and the impurities enter the collection box 41 through the collection pipe 47. The centrifugal fan 42 synchronously sucks the suspended dust inside the machine tool 1 and discharges it after being filtered by the collection box 41, which can effectively clean the impurities inside the machine tool 1 and outside the rotating shaft 31 by partition dust removal. When the rotating shaft 31 rotates, the eccentric block 512 drives the long suction pipe 54 to reciprocally slide through the driving plate 56 and the return spring 55, extracts the lubricating oil from the oil storage tank 51, injects it into the oil distribution ring 58 through the oil guiding pipe 510, and then lubricates the bearing 57 through the oil injection hole 59. By setting the pressure spring 516 and the pressing plate 515, the pressure in the oil storage tank 51 is maintained stable to ensure the continuous supply of lubricating oil. The stable operation of the transmission components is ensured through the guide shaft 511 and the limit post 79; the protective cover protects the reciprocating lead screw 61, and the partition plate 8 isolates the aggregate area. Through the above structure and process, the laser cutting machine realizes the synchronous integration and automatic operation of cutting, cleaning, dust removal and lubrication.
