DETAILED DESCRIPTION

[0027] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0028] like Figures 1 to 3 As shown, a metal laser cutting device for hardware accessories according to an embodiment of the present invention comprises a base 1, on which a symmetrically arranged support rod 11 is threadedly mounted, a top connecting rod 12 is fixedly mounted on the top of the support rod 11, a laser cutting head 13 is fixedly mounted on the bottom center of the top connecting rod 12, a plurality of bottom fixing rods 14 are fixedly mounted on the bottom of the base 1, a plurality of symmetrically arranged first rotating rods 18 are rotatably mounted inside the base 1, a supporting tooth 17 is fixedly mounted on the end of the first rotating rod 18, a first slide groove 19 is fixedly mounted on the lower part of the base 1, a grinding device 2 is slidably mounted inside the first slide groove 19, and the grinding device 2 is used to grind the supporting tooth 17;

[0029] like Figures 3 to 6As shown, the grinding device 2 includes a grinding support 21, a first limit block 22, and a first grinding ring 23. The grinding support 21 is slidably installed inside the first slide groove 19. The top of the grinding support 21 is provided with a first limit block 22 and a first grinding ring 23. The first grinding ring 23 is used to grind the molten metal liquid adhered to the outer wall of the supporting tooth 17.

[0030] It should be noted that when cutting the metal sheet of the hardware, the metal sheet of the hardware is placed on the support teeth 17, and then the cutting position is adjusted by moving the support rod 11 and the laser cutting head 13. When the metal sheet is cut, the molten metal will drip onto the support teeth 17, and then the molten metal will adhere to the top of the support teeth 17. When the workpiece is placed on the support teeth 17 again after cutting, the flatness deviation will occur. In order to solve this problem, the following improvements have been made;

[0031] A first slide 19 is provided at the lower part of the base 1, and the base 1 is provided inside the first slide 19. After the cutting is completed, the workpiece is moved out of the surface of the supporting teeth 17, and then the first rotating rod 18 is rotated 180 degrees. The rotation of the first rotating rod 18 drives the supporting teeth 17 to rotate, so that the supporting teeth on the supporting teeth 17 are directed downward, and a grinding support 21 is provided inside the first slide 19. By adjusting the grinding support 21, the grinding support 21 is moved to the lower end of the supporting teeth 17 that need to be cleaned, and then the first grinding ring 23 is driven by the motor to rotate, from The cutting melt adhered to the supporting teeth 17 is polished to prevent the supporting teeth 17 from being in a state of height correction due to the adhesion of the cutting melt, thereby improving the accuracy of cutting. When it is necessary to polish the surface of the supporting teeth 17, the polishing support 21 can be adjusted to move the first polishing ring 23 toward the supporting teeth 17, and the first polishing ring 23 can be rotated to polish the outside of the supporting teeth 17 until the polishing is completed. The polishing support 21 can be adjusted again to make the first limit block 22 and the first polishing ring 23 descend and reset, thereby completing the polishing work.

[0032] like Figures 1 to 2 As shown, the ends of the plurality of first rotating rods 18 are fixedly mounted with first gears 16 , and the side of the base 1 is rotatably mounted with a first threaded rod 15 , which is engaged with the plurality of first gears 16 .

[0033] It should be noted that when it is necessary to adjust the direction and limit the multiple supporting teeth 17, it is rather troublesome to adjust the direction of the first rotating rod 18 one by one. Therefore, a first gear 16 is provided on the first rotating rod 18, and multiple first gears 16 are engaged with the first threaded rod 15. When it is necessary to adjust the direction of the supporting teeth 17, the first threaded rod 15 can be driven by a motor to rotate, and the first threaded rod 15 can drive the multiple first rotating rods 18 and the supporting teeth 17 to rotate synchronously, thereby achieving the purpose of adjusting the direction and limit of the supporting teeth 17. Thereafter, by adjusting the grinding support 21, the multiple supporting teeth 17 can be ground.

[0035] It should be noted that, considering that it is necessary to grind multiple surfaces of the supporting teeth on the supporting teeth 17 and to adapt to the shape of the cutting melt adhered to the surface of the supporting teeth 17 during grinding, a second connecting member 27 is rotatably connected to the first limit block 22, and a mounting member 26 is connected to the second connecting member 27. The multiple mounting members 26 are connected through the first connecting member 25. Therefore, when the second connecting member 27 is driven to rotate by the motor, the multiple mounting members 26 can be driven to rotate, thereby driving the first grinding ring 23 on the outer wall of the mounting member 26 to rotate, and the rotation of the first grinding ring 23 can support the teeth 17. The external supporting teeth are polished, and a second polishing piece 24 is provided on the polishing support 21. The rotation of the polishing support 21 can drive the first limit block 22, the first polishing ring 23, and the second polishing piece 24 to move toward the supporting tooth 17. The second polishing piece 24 is provided with the same first polishing ring 23, the first connecting piece 25, the mounting piece 26, and the second connecting piece 27 as the first limit block 22. Therefore, the second polishing piece 24 can also polish the supporting tooth 17 and adapt to the shape of the molten cutting fluid adhered to the supporting tooth 17, so as to facilitate the polishing of the surface of the supporting tooth 17.

A fourth gear 216 is rotatably installed on the side of the first moving block 211, and a fifth gear 217 is rotatably installed on the top of the first moving block 211. The fourth gear 216 is engaged with the second threaded rod 215 and the fifth gear 217. One of the sixth rotating rods 218 is threadedly connected to the first moving block 211, and the other sixth rotating rod 218 is slidably connected to the first moving block 211. The second gear 212 is slidably connected to the sixth rotating rod 218.

[0037] It should be noted that when the position of the first moving block 211 needs to be adjusted, the length position of the first moving block 211 on the base 1 can be adjusted by rotating one of the sixth rotating rods 218, and the width position of the first moving block 211 on the base 1 can be adjusted by moving the third slider 219. By rotating the other third slider 219, the second gear 212, the third gear 213 and the second threaded rod 215 can be driven to rotate, and the rotation of the second threaded rod 215 drives the fourth gear 216 to rotate, thereby driving the fifth gear 217 to rotate, adjusting the second grinding piece 24, the first limit block 22 and the first grinding ring 23 to move closer to the supporting teeth 17. When the second grinding piece 24 and the first grinding ring 23 rise, the surface of the supporting teeth 17 is ground, thereby improving the service life of the supporting teeth 17.

[0039] It should be noted that when the fifth gear 217 rotates, it drives the fourth threaded rod 243 to rotate, thereby driving the fourth connecting block 241 and the fourth telescopic rod 244 to move toward the direction close to the supporting teeth 17. Then, the fourth rotating column 247 is driven to rotate by the motor, which can drive the edge grinding ring 248 to rotate, thereby achieving the purpose of approaching the supporting teeth 17 and grinding the surface of the supporting teeth 17.
