Description

Technical Field

[0001] The utility model relates to the technical field of tempered glass processing, in particular to a positioning fixture for a tempered glass processing platform. Background Art

[0002] Tempered glass is a prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby increasing the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc.

[0003] After searching, a tooling fixture for tempered glass processing with announcement number CN215470642U was found. The tooling fixture for tempered glass processing includes: a workbench; a frame, the bottom of which is fixed to the top of the workbench. The tooling fixture for tempered glass processing provided by the utility model can indirectly drive the glass clamping device on the right to move to the left through the threaded rod by turning the rotating handle. When one side of the tempered glass completely enters the clamping placement groove inside the glass clamping device on the right, the fixation of both sides of the tempered glass can be completed, and then the top of the tempered glass can be clamped by pressing the pressing plate downward. Since a plurality of positioning grooves are provided on the pressing rod, the different positions of the pressing rod can be conveniently limited by the coordinated use of the positioning rod and the positioning groove, so that tempered glass of different thicknesses can be conveniently clamped, thereby expanding the overall application range of the device and facilitating use by the staff;
