Embodiment Construction

[0008] The present invention will be further described below in conjunction with the drawings.

[0009] Reference figure 1 , figure 2 , A universal fixture suitable for testing the strength of glass of multiple sizes of mobile phones includes four support blocks, each support block is provided with threaded holes 1 on both ends of the support block, and each support block is provided with a concave and convex platform 3 on the end surface. The side of the support block is provided with through-slot holes 2, and screws 4 are used to pass through the threaded holes 1 and through-slot holes 2 on the four support blocks respectively, and the four support blocks are fixedly connected into one body to form a four support block. The product support surface 5 of the concavo-convex platform 3 combination.

[0010] The invention is made by processing acrylic materials. The minimum size of the universal clamp is 17mm×17mm; the maximum size is 133mm×133mm. The fixture uses four acrylic sup...

Abstract

The invention relates to a universal clamp suitable for detecting glass strength of mobile phones in various sizes, which comprises four supporting blocks. Side surfaces at both ends of each supporting block are provided with screw holes respectively and the end surface of each supporting block is provided with a concave-convex table. The side surface of each supporting block is provided with a through groove hole. The screw holes and through groove holes on the four supporting blocks are penetrated through by bolts respectively to fixedly connect the four supporting blocks so as to form a product supporting surface combined by the concave-convex tables on the four supporting blocks. The size of the clamp can be changed by moving the position of the bolt in the through groove hole and the glass strength of products in various sizes can be detected by the clamp. The clamp is convenient and practical and reduces the cost.

Description

Technical field [0001] The invention relates to a glass strength detection device, in particular to a universal clamp suitable for detecting the strength of glass of various sizes of mobile phones. Background technique [0002] In recent years, with the rapid development of science and technology, glass materials and their products have entered or are entering the high-tech field, and have become irreplaceable cutting-edge functional materials. At present, competition in the mobile phone market is becoming increasingly fierce, and people have higher and higher requirements for the appearance quality of mobile phone glass lenses. The strength of glass is an important performance index of the appearance quality of mobile phones. Therefore, various tests on the strength of glass are required in the sample delivery to customers and actual production. For example: falling ball test, surface stress, four-point bending, etc. Among them, the falling ball test is the most effective and p...
