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

[0022] As Figure 1-2 shown, the present utility model provides a 3D glass polishing fixture, including a base 1 and a side protection dental brace 2. A bearing boss 3 is provided on the base 1, and a profiling surface adapted to the concave / convex surface of the 3D glass is provided on the bearing boss 3. The side protection dental brace 2 is of an annular structure and is made of an injection molding strip customized according to the arc height and outer shape of the 3D glass product. The side protection dental brace 2 is suitably sleeved on the outer edge of the bearing boss 3, and the top surface of the side protection dental brace 2 extends upward above the bearing boss 3, so that when the 3D glass is suitably placed on the bearing boss 3, the height of the side protection dental brace 2 is higher than the height of the edge of the 3D glass. When the 3D glass polishing device is working, the side protection dental brace 2 can ensure that the 3D glass will not be swept and collapsed around during the polishing by the brush disc, achieving the effect of protecting the chamfer of the 3D glass, ensuring the product quality, improving the yield, and at the same time can play a role in positioning the placement of the 3D glass, reducing the rework rate of the 3D glass polishing process.

[0023] As Figure 3 shown, the polishing fixture further includes a clamping assembly 4 sleeved on the outer edge of the bearing boss 3. The clamping assembly 4 has an annular bottom plate 41 and an annular side plate 42 vertically connected to one side of the bottom plate 41. The bottom plate 41 is fixedly installed between the side protection dental brace 2 and the base 1, so that the side protection dental brace 2 is in interference fit between the bearing boss 3 and the side plate 42. The inner side surface of the side protection dental brace 2 is in close contact with the bearing boss 3, and the outer side surface of the side protection dental brace 2 is in close contact with the side plate 42, so as to clamp and fix the side protection dental brace 2 from the circumferential direction of the side protection dental brace 2 towards the bearing boss 3 through the clamping assembly 4, which is convenient for disassembly and replacement, saving time and labor.

[0024] As Figure 4As shown, the polishing fixture further includes an annular gasket 6, and the gasket 6 is adapted to the bottom plate 41, so that when the height of the edge protection dental appliance 2 is lower than the height of the 3D glass edge, it is adaptively installed between the bottom plate 41 and the base 1 to raise the height of the edge protection dental appliance 2 to be higher than the height of the 3D glass edge. The gaskets 6 are provided in plurality, and the thickness of each gasket 6 is 0.8 mm - 1 mm. Whenever the height of the edge protection dental appliance 2 wears down to be lower than the height of the 3D glass edge, that is, when the edge protection dental appliance reaches its service life, only one layer of gasket 6 needs to be adaptively installed between the bottom plate 41 and the base 1, so that the height of the edge protection dental appliance 2 can be higher than the height of the 3D glass edge again, thus it can continue to be used without replacing the edge protection dental appliance 2, effectively improving the service life of the edge protection dental appliance 2, reducing the cost, and keeping the height of the edge protection dental appliance higher than the height of the 3D glass edge during use until the edge protection dental appliance wears down to be lower than the preset height and then is replaced.

[0025] A number of threaded counterbores 43 are formed on the bottom plate 41, a number of threaded through holes 61 corresponding to the threaded counterbores 43 are formed on the gasket 6, and a number of threaded blind holes 11 corresponding to the threaded counterbores 43 are formed on the base 1. The threaded counterbores 43, the threaded through holes 61 and the threaded blind holes 11 are connected by bolts 5 to fixedly install the bottom plate 41 and the gasket 6 on the base 1, which is convenient for disassembly and assembly. When additional gaskets 6 need to be installed, the staff only needs to remove the edge protection dental appliance 2, then screw out the bolts 5 from the threaded blind holes 11, place the additional gasket 6 to be installed on the base 1, align the threaded through holes 61 of the installed gasket 6 with the threaded blind holes 11 of the base 1, screw in the bolts 5 for fixation, and finally clamp and fix the edge protection dental appliance 2 again between the load-bearing boss 3 and the side plate 42.

[0026] As Figure 5 shown, negative pressure suction holes 31 penetrating through the load-bearing boss 3 and the base 1 are provided on the bottom surface of the load-bearing boss 3. The negative pressure suction holes 31 are connected to a negative pressure suction device through a vacuum valve to adsorb and fix the 3D glass adaptively placed on the load-bearing boss 3. A number of negative pressure suction grooves 32 are evenly distributed on the bottom surface of the load-bearing boss 3 and connecting grooves 33 connecting the negative pressure suction holes 31 and the number of negative pressure suction grooves 32 are provided to increase the adsorption area of the load-bearing boss 3. Among them, the negative pressure suction holes 31 are designed at the center of the base 1 and the diameter of the negative pressure suction holes 31 is 15 - 20 mm, and the widths of the negative pressure suction grooves 32 and the connecting grooves 33 are both 5 mm.

[0027] The 3D glass polishing fixture provided by the present utility model is adapted to place a 3D glass by arranging a bearing boss 3 with a profiling surface on a base 1, and a protective edge dental brace 2 is properly sleeved on the outer edge of the bearing boss 3, and the height of the protective edge dental brace 2 is higher than the height of the edge of the 3D glass. When the 3D glass polishing device works, the protective edge dental brace 2 can ensure that the 3D glass will not be swept and collapsed around during the polishing of the brush disc, achieving the effect of protecting the chamfer of the 3D glass, ensuring the product quality, improving the yield, and at the same time can play a role in positioning the 3D glass placement, reducing the rework rate of the 3D glass polishing process. By arranging a plurality of annular gaskets 6, whenever the height of the protective edge dental brace 2 is worn to be lower than the height of the edge of the 3D glass, that is, when the protective edge dental brace reaches the service life, only one layer of gasket 6 needs to be properly installed between the bottom plate 41 and the base 1, so that the height of the protective edge dental brace 2 is higher than the height of the edge of the 3D glass again, and thus it can continue to be used without replacing the protective edge dental brace 2, effectively improving the service life of the protective edge dental brace 2 and reducing the cost.
