The core of the utility model is to provide a straight body limit polishing clamp of 3D curved surface glass can ensure that the luminance on the straight body limit of 3D curved surface glass is even.
Referring to fig. 4-10, fig. 4 is a schematic structural view of a 3D curved glass straight edge polishing fixture according to an embodiment of the present invention; FIG. 5 is a schematic structural view of the 3D curved glass after being mounted on the 3D curved glass straight edge polishing fixture shown in FIG. 4; FIG. 6 is a partial enlarged view of B in FIG. 5; FIG. 7 is an exploded view of one of the views of FIG. 1; FIG. 8 is an exploded view from another perspective of FIG. 1; FIG. 9 is a top view of FIG. 1; fig. 10 is a bottom view of fig. 1.
The utility model provides a 3D curved surface glass straight edge polishing clamp mainly includes fixed box 1 of product and fixed box stopper 2 etc..
Specifically, the fixed box 1 of product is used for fixed 3D curved surface glass, and 3D curved surface glass superposes in the fixed box 1 of product, and the major structure of the fixed box 1 of product can be the same with the structure of conventional rectangle tool box among the prior art.
The utility model discloses a focus is on, sets up fixed box stopper 2 respectively in the both sides of the fixed box 1 of product, and fixed box stopper 2 has convex radial edge part 212, and radial edge part 212 radially surpasss the arris 111 of the fixed box 1 of product.
When the straight body edge of the 3D curved glass needs to be polished, the 3D curved glass is fixed in the product fixing box 1, then the product fixing box 1 and the fixing box limiting block 2 are integrally installed on a machine table of the polishing device, and a rotating shaft of the machine table drives the product fixing box 1 and the fixing box limiting block 2 to integrally rotate so as to polish the straight body edge of the 3D curved glass.
It can be understood that, because the radial edge portion 212 radially exceeds the side edge 111 of the product fixing box 1, during the rotation process of the 3D curved glass, the radial edge portion 212 of the fixing box limiting block 2 is transited to the straight side of the 3D curved glass (as shown in B in fig. 5 and 6), and because the radial edge portion 212 is arc-shaped and has a certain radian, compared with the prior art that the planar side edge end surface of the rectangular jig box is transited to the straight side of the 3D curved glass, the arc-shaped radial edge portion 212 can enable the polishing brush to be transited to the 3D curved glass more smoothly, thereby avoiding the existence of polishing dead corners, so that the straight side of the 3D curved glass is polished more uniformly, and the uniformity of the overall brightness of the straight side of the 3D curved glass is ensured.
It should be noted that, in this embodiment, the specific connection manner of the product fixing box 1 and the fixing box limiting block 2 is not limited, as long as the above-mentioned relative position relationship between the two can be ensured. For example, the fixed box stopper 2 can be directly fixedly connected with the side wall of the product fixed box 1, and the fixed box stopper and the side wall are connected into an integral structure.
Certainly, in order to put 3D curved glass into the product fixing box 1 conveniently, as an optimal scheme, on the basis of the above embodiment, a limiting groove for limiting the product fixing box 1 is formed between the fixing box limiting blocks 2, and the product fixing box 1 is in sliding fit with the limiting groove.
That is to say, the fixed box 1 of product in this embodiment is the components of a whole that can function independently structure with the fixed box stopper 2 of its both sides, forms the spacing groove between two fixed box stoppers 2, and the spacing groove is used for spacing fixed box 1 of product.
