Description

Technical Field

[0001] This utility model relates to the field of glass processing fixture technology, and in particular to a right-angle positioning fixture. Background Technology

[0002] After the glass panels are cut, an L-shaped corner bracket is used to position them. By setting the positioning, the cut pieces of glass can be quickly fixed in a right-angle positioning fixture for processing.

[0003] To meet the required number of uses, jigs are generally made of relatively expensive materials. However, most existing jigs are one-piece structures. When the jig reaches the end of its service life, the main parts in contact with the glass panel are severely worn, requiring the entire jig to be replaced. This results in a waste of materials and increases the cost of using the jig. Therefore, further improvements are needed. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Compared with existing technologies, by implementing a split structure design for the positioning fixture, it is possible to quickly install, disassemble, and replace the main frame and the sub-frame. While ensuring its service life, it can effectively reduce the overall manufacturing cost of the fixture. Furthermore, by setting sub-frames of different sizes to adapt to the main frame, it can be adapted to the processing of glass panels of different sizes. And through the design of anti-loosening shims and pre-tightening force, the stability of the fixture during the glass panel processing can be ensured. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, this embodiment provides a right-angle positioning fixture, including:

[0023] Main frame 1;

[0024] The sub-frame 2 has a first protrusion 21 and a second protrusion 22. The first protrusion 21 and the second protrusion 22 are respectively adapted to the first slot 13 and the second slot 14 opened on the main frame 1 so that the outer side wall of the sub-frame 2 fits against the inner side wall of the main frame 1.

[0025] Overall, the first protrusion 21 and the second protrusion 22 are adapted to the first slot 13 and the second slot 14 respectively, so that the outer wall of the sub-frame 2 is completely attached to the inner wall of the main frame 1 to realize the connection between the sub-frame 2 and the main frame 1, and attach the glass substrate to the inner wall of the sub-frame 2 to realize the right angle positioning reference. During the positioning and processing of the glass panel, the glass panel is attached to the first wall 25 and the second wall 26 on the sub-frame 2 respectively, and finally the processing of the glass panel is completed.

[0026] like Figures 2-3 As shown, in this embodiment, both the first protrusion 21 and the second protrusion 22 are dovetail tenon structures, and the first slot 13 and the second slot 14 are non-through structures.

[0027] Specifically, designing the first protrusion 21 and the second protrusion 22 as dovetail joints can effectively improve the firmness of the connection between the main frame 1 and the sub-frame 2, and also improve the durability of the main frame 1. This allows the first protrusion 21 to be matched with the first groove 13 and the second protrusion 22 to be matched with the second groove 14. Furthermore, the first groove 13 and the second groove 14 are designed as non-fully through-hole joints, which can prevent misalignment during the installation of the sub-frame 2 due to excessive force.

[0028] like Figures 1-2 As shown, in this embodiment, a first bolt and a second bolt are also included. A first through hole 11 and a second through hole 12 are provided on the main frame 1. A first screw hole 23 is provided on the first protrusion 21 and a second screw hole 24 is provided on the second protrusion 22. The first bolt passes through the first through hole 11 and is adapted to the first screw hole 23, and the second bolt passes through the second through hole 12 and is adapted to the second screw hole 24.

[0029] Specifically, it also includes a first bolt and a second bolt. After the outer wall of the sub-frame 2 is fully fitted with the inner wall of the main frame 1, the first bolt is passed through the first through hole 11 and fitted with the first screw hole 23. The second bolt is passed through the second through hole 12 and fitted with the second screw hole. This can prevent the sub-frame 2 from moving along the direction of the first slot 13 / second slot 14 during the processing of the glass panel, and can further improve the stability between the sub-frame 2 and the main frame 1.

[0030] like Figures 1-2 As shown, in this embodiment, the main frame 1 is made of PVC material, and the secondary frame 2 is made of PEEK material.

[0031] Specifically, the main frame 1 is made of PVC material, and the secondary frame 2 is made of PEEK material. This not only ensures the service life of the secondary frame 2, but also saves costs.

[0032] like Figures 1-2 As shown, in this embodiment, the main frame 1 is also provided with a recessed portion 15, and the outer wall of the main frame 1 is provided with chamfers and rounded corners.

[0033] Specifically, the main frame 1 is provided with a recessed part 15. By setting the recessed part 15, the material used in the main frame 1 can be further saved and the overall cost of the fixture can be reduced. By setting chamfers and rounded corners, the safety of the main frame 1 can be further improved, and workers can be prevented from being scratched or caused by collision damage during operation.

[0034] like Figures 1-2 As shown, in this embodiment, the outer walls of the main frame 1 and / or the sub-frame 2 are provided with scale marks for size reference when positioning the workpiece.

[0035] Specifically, by providing scale markings on the outer walls of the main frame 1 and / or the sub-frame 2, scale assistance can be provided to workers, enabling them to quickly position the glass panel and thus improve the processing efficiency of the glass panel.

[0036] like Figures 1-2 As shown, in this embodiment, the heads of the first bolt and the second bolt are provided with anti-loosening washers, and the first bolt end is threaded to the first screw hole 23 to form a preload, and the second bolt end is threaded to the second screw hole 24 to form a preload.

[0037] Specifically, anti-loosening washers are installed on the heads of the first and second bolts, which can further improve the tightening effect of the first and second bolts and prevent the main frame 1 and the sub-frame 2 from loosening during the processing of the glass panel. The bolt preload can compensate for the difference in material rigidity, further improving the stability between the main frame 1 and the sub-frame 2.

[0038] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider 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.
