Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a three-dimensional five-axis laser cutting machine. Background Art

[0002] A three-dimensional five-axis laser cutting machine is a high-precision laser processing device used for cutting various materials with complex shapes.

[0003] The "three-dimensional five-axis laser cutting machine" disclosed in the patent number "CN206393067U" uses a laser to cut leather materials.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1-6 shown, a three-dimensional five-axis laser cutting machine includes a laser cutting machine body 1 and a processing table 2: a processing table 2 is installed inside the laser cutting machine body 1, a portable protection mechanism 3 is arranged above the processing table 2, a debris cleaning mechanism 4 is arranged on the side of the portable protection mechanism 3, and a portable collection mechanism 6 is arranged on the side of the debris cleaning mechanism 4. The portable protection mechanism 3 includes a protection table 31, positioning threaded grooves 32, docking threaded grooves 33 and positioning bolts 34. A protection table 31 is attached to the top outer wall of the processing table 2. Two groups of positioning threaded grooves 32 are symmetrically and penetratingly opened on the top outer wall of the protection table 31. Two groups of docking threaded grooves 33 are correspondingly opened on the top outer wall of the processing table 2. The positioning threaded grooves 32 and the docking threaded grooves 33 are threadedly installed with the positioning bolts 34. The setting of the protection table 31 here plays a protective effect on the processing table 2. When the protection table 31 needs to be replaced after being damaged, at this time, only need to completely screw out the positioning bolt 34 from the inside of the positioning threaded groove 32, and then the protection table 31 changes from the locked state to the movable state. Then directly remove the old protection table 31 and replace it with a new protection table 31. When installing the new protection table 31, only need to adjust its position appropriately and then pass the positioning bolt 34 through the positioning threaded groove 32 and screw it to the bottom of the docking threaded groove 33 to complete the installation.

[0025] The debris cleaning mechanism 4 includes a placement box 41, a positioning box 42, a driving motor 43, a transmission shaft 44 and a limiting fan 45. A placement box 41 is provided on the outer side wall of the processing table 2. A positioning box 42 is provided on the top outer wall of the placement box 41. The outer side wall of the positioning box 42 facing the processing table 2 is an open structure. A driving motor 43 is provided on the inner side wall of the positioning box 42. The driving motor 43 is connected to one end of the transmission shaft 44. The other end of the transmission shaft 44 is connected to the limiting fan 45. There are two groups of transmission shafts 44. A driving wheel 46 is provided on the outside of the first group of transmission shafts 44. A transmission wheel 47 is provided on the outside of the second group of transmission shafts 44. A transmission belt 48 is connected between the driving wheel 46 and the transmission wheel 47. A limiting partition 49 is provided on the side of the limiting fan 45. The outer side wall of the limiting partition 49 is connected to the inner side wall of the positioning box 42. And the outer side wall of the limiting partition 49 at the position of the limiting fan 45 is a filter structure. A support shaft 51 is provided on the outer side wall of the limiting fan 45 at the position of the rotating shaft. The support shaft 51 penetrates through the limiting partition 49 and is connected to a limiting scraper 52. And the limiting scraper 52 is an arc-shaped structure. When it is necessary to clean the laser cutting debris on the table, at this time, only the driving motor 43 needs to be turned on. Here, it should be noted that the limiting fan 45 is installed in the reverse direction, and its air outlet end faces the driving motor 43. When the driving motor 43 is turned on, it will automatically drive the transmission shaft 44 to rotate and then drive the limiting fan 45 to rotate. At the same time, when the above-mentioned transmission shaft 44 rotates, it will also synchronously drive the driving wheel 46, the transmission wheel 47 and the transmission belt 48 to drive, so as to achieve the effect of synchronously driving the two groups of limiting fans 45 to rotate synchronously. When the limiting fan 45 rotates, it will automatically suck the debris above the protective table 31 into the positioning box 42. Here, due to the setting of the limiting partition 49, the debris will be blocked by the filter. At the same time, when the above-mentioned limiting fan 45 rotates, it will also synchronously drive the support shaft 51 to rotate and then drive the limiting scraper 52 to rotate. As the limiting scraper 52 rotates, it will automatically clean the side of the filter, so as to achieve the anti-blocking effect. Here, it should be noted that a through groove is opened in communication between the bottom inner wall of the positioning box 42 on the side of the limiting partition 49 and the following collection box 61. Then, the debris on the side of the limiting partition 49 can enter the collection box 61 through the through groove for centralized collection. And the debris accumulated on the outer wall of the part of the limiting partition 49 where no filter is provided in the middle will automatically fall into the collection box 61 under the action of gravity.

[0026] The portable collection mechanism 6 includes a collection box 61, positioning blocks 62 and positioning T-shaped bars 63. An opening structure is provided on the outer wall of the side of the placement box 41 facing away from the processing table 2, and a collection box 61 is arranged inside the placement box 41. Two groups of positioning blocks 62 are symmetrically arranged on the outer wall of the side of the collection box 61, and positioning T-shaped bars 63 are arranged on the outer wall of the side of the positioning blocks 62. Two groups of first threaded grooves 64 are symmetrically and penetratingly opened on the outer wall of the side of the positioning blocks 62. Two groups of positioning slots 65 are correspondingly opened on the outer wall of the side of the placement box 41. The positioning blocks 62 and the positioning slots 65 are snap-fitted. A positioning T-shaped groove 66 is opened on the outer wall of the side of the placement box 41 at the position of the positioning slot 65. The positioning T-shaped bar 63 and the positioning T-shaped groove 66 are slidably installed. Two groups of second threaded grooves 67 are symmetrically opened on the outer wall of the side of the placement box 41 at the position of the positioning T-shaped groove 66. The first threaded grooves 64 and the second threaded grooves 67 are threadedly installed with fastening bolts 68; when it is necessary to take out the collection box 61 from the inside of the placement box 41 to clean the debris and impurities inside it, at this time, only need to screw out the fastening bolt 68 from the inside of the first threaded groove 64, and then the collection box 61 changes from the locked state to the movable state. Then directly pull the handle on the side of the collection box 61 to pull it out from the inside of the placement box 41. Here, it should be noted that the top of the collection box 61 is provided with an opening structure, and it can be directly poured out during cleaning. When reinstalling, at this time, it is necessary to adjust the collection box 61 to a suitable position and then push the positioning T-shaped bar 63 on its side into the positioning T-shaped groove 66 at the corresponding position. When the positioning block 62 is stuck to the bottom of the positioning slot 65, at this time, the first threaded groove 64 and the second threaded groove 67 are in a corresponding fitting state. Then directly pass the fastening bolt 68 through the first threaded groove 64 and screw it to the bottom of the second threaded groove 67 to complete the installation.

[0027] When the present utility model is in use, the setting of the protective table 31 here plays a protective effect on the processing table 2. When the protective table 31 needs to be replaced after being damaged, at this time, only need to completely screw out the positioning bolt 34 from the inside of the positioning threaded groove 32, and then the protective table 31 changes from the locked state to the movable state. Then directly remove the old protective table 31 and replace it with a new one. When installing the new protective table 31, only need to adjust it to a suitable position and then pass the positioning bolt 34 through the positioning threaded groove 32 and screw it to the bottom of the docking threaded groove 33 to complete the installation;

[0028] When it is necessary to clean the laser cutting debris on the tabletop, only the drive motor 43 needs to be turned on at this time. Here, it should be noted that the limit fan 45 is installed in the reverse direction, and its air outlet end faces the drive motor 43. When the drive motor 43 is turned on, it will automatically drive the transmission shaft 44 to rotate, and then drive the limit fan 45 to rotate. At the same time, when the transmission shaft 44 rotates, it will also synchronously drive the drive wheel 46, the transmission wheel 47 and the transmission belt 48 to drive, so as to achieve the effect of synchronously driving the two limit fans 45 to rotate synchronously. When the limit fan 45 rotates, it will automatically suck the debris above the protective table 31 into the positioning box 42. Here, due to the setting of the limit partition 49, the debris will be blocked by the filter screen. At the same time, when the limit fan 45 rotates, it will also synchronously drive the support shaft 51 to rotate and then drive the limit scraper 52 to rotate. As the limit scraper 52 moves along its rotation trajectory, it will automatically clean the side of the filter screen, thus achieving the anti-blocking effect. Here, it should be noted that a through groove is provided in communication between the inner wall of the bottom end of the side of the limit partition 49 and the following collection box 61. Therefore, the debris on the side of the limit partition 49 can enter the collection box 61 through the through groove for centralized collection, and the debris accumulated on the outer wall of the part of the limit partition 49 without a filter screen in the middle will automatically fall into the collection box 61 under the action of gravity;

[0029] When it is necessary to take out the collection box 61 from the inside of the placement box 41 to clean the debris and impurities inside it, only the fastening bolt 68 needs to be screwed out from the inside of the first thread groove 64 at this time. Then, the collection box 61 changes from the locked state to the movable state. Subsequently, directly pull the handle on the side of the collection box 61 to pull it out from the inside of the placement box 41. Here, it should be noted that the top of the collection box 61 is provided with an open structure, and it can be directly poured out during cleaning. When reinstalling, at this time, the collection box 61 needs to be adjusted to the appropriate position, and then the positioning T-shaped strip 63 on its side is pushed into the positioning T-shaped groove 66 at the corresponding position. When the positioning block 62 is stuck to the bottom end of the positioning groove 65, at this time, the first thread groove 64 and the second thread groove 67 are in a corresponding and fitting state. Subsequently, directly pass the fastening bolt 68 through the first thread groove 64 and screw it to the bottom end of the second thread groove 67 to complete the installation.

[0030] Here, it should be noted that the above drive motor 43 can be powered according to the existing technology, whether it is powered by a power supply component or an external wire. At the same time, the workpiece cutting and the corresponding program programming operations can be carried out according to the existing operation technical standards, which are all existing conventional operation technical means and will not be described in detail here.

[0031] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
