DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1-5 The utility model provides a thin metal sheet laser cutting machine, comprising a laser cutting head 1, a mounting bracket 15 is installed on the outer wall of the laser cutting head 1, a small motor 3 is installed at one end of the mounting bracket 15 away from the laser cutting head 1, a power gear 4 is installed at the output end of the small motor 3, a mounting ring seat 2 is installed on the outer wall of the laser cutting head 1 and located below the mounting bracket 15, a transmission gear ring 5 for transmission is installed on the outer wall of the mounting ring seat 2, the power gear 4 is meshed with the transmission gear ring 5, a lower extension mounting seat 6 is installed at the bottom of the mounting ring seat 2, an elastic telescopic support 7 is installed at the bottom of the lower extension mounting seat 6, a grinding pad ring seat 8 is installed at the bottom end of the elastic telescopic support 7, a connecting seat 9 is installed at the bottom of the grinding pad ring seat 8, a grinding sheet 10 is installed at the bottom of the connecting seat 9, an inner mounting ring 11 is installed on the inner side of the lower extension mounting seat 6, an inner adsorption magnet 12 is installed at the bottom of the inner mounting ring 11, an outer mounting ring 13 is installed on the outer side of the lower extension mounting seat 6, and an outer adsorption magnet 14 is installed at the bottom of the outer mounting ring 13.

[0021] Furthermore, the bottom of the connecting seat 9 and the top of the grinding sheet 10 are connected by magic adhesive, which is convenient for replacement, and the magic adhesive connection has high transmission stability in the horizontal direction and will not slip.

[0022] Furthermore, the inner and outer sides of the connecting seat 9 and the grinding sheet 10 are bent downward, so that when the grinding sheet 10 is pressed downward to contact the surface of the metal plate, the outer and inner sides of the grinding sheet 10 will not bend upward due to insufficient pressure, resulting in a reduction in the grinding area.

[0023] Furthermore, a spring is installed inside the elastic telescopic support 7, and a downward grinding pressure is applied to the grinding pad ring seat 8, the connecting seat 9 and the grinding sheet 10 by compressing the spring inside the elastic telescopic support 7.

[0024] Further, threaded rings are provided on both the inner and outer surfaces of the lower extension mount 6. The inner mounting ring 11 is threadedly connected to the lower extension mount 6, and the outer mounting ring 13 is threadedly connected to the lower extension mount 6. The inner diameter of the grinding pad ring seat 8 is larger than the outer diameter of the inner mounting ring 11, and the outer diameter of the grinding pad ring seat 8 is smaller than the inner diameter of the outer mounting ring 13, so that the inner mounting ring 11 can pass through the inside of the grinding pad ring seat 8, and the outer mounting ring 13 can pass through the outside of the grinding pad ring seat 8.

[0025] Further, the connecting seat 9 is made of sponge. When the inner mounting ring 11 is installed by passing through the inside of the grinding pad ring seat 8, the connecting seat 9 and the grinding piece 10 are deformed by extrusion, and they will not block the installation of the inner mounting ring 11 and the outer mounting ring 13.

[0026] During use, the small motor 3 drives the driving gear 4 to rotate. The driving gear 4 drives the transmission gear ring 5 to rotate. The transmission gear ring 5 drives the mounting ring seat 2 to rotate. The mounting ring seat 2 drives the grinding pad ring seat 8 to rotate through the lower extension mount 6 and the elastic telescopic strut 7. The grinding pad ring seat 8 drives the connecting seat 9 and the grinding piece 10 to rotate. The grinding piece 10 grinds and cleans the residual metal liquid on the surface of the metal plate, so that the cutting position on the surface of the metal plate will not have residual metal liquid affecting the smoothness of the metal plate surface, improving the quality of the cut. At the same time, the flying debris during grinding is adsorbed by the inner adsorption magnet 12 and the outer adsorption magnet 14 above. There is no need to manually clean the surface of the plate after cutting, reducing the processing procedures, facilitating subsequent processing, and preventing debris from remaining on the plate surface, which may block the laser when the laser passes through the debris and affect the cutting effect of the laser. After the cutting work is completed, the outer adsorption magnet 14 is disassembled by rotating the outer adsorption magnet 14 to drive the outer mounting ring 13 to rotate, and the inner adsorption magnet 12 is disassembled by rotating the inner adsorption magnet 12 to drive the inner mounting ring 11 to rotate. Then, the debris on the surfaces of the inner adsorption magnet 12 and the outer adsorption magnet 14 can be cleaned, and the cleaning operation is simple.
