Toughened glass fragment test immobilization method

Abstract

The invention relates to a toughened glass testing device, and discloses a toughened glass fragment test immobilization method. According to the improved toughened glass testing device, a bearing slide rail pressing plate subassembly is immobilized on the flat surface of a test platform; slide cooperation of a rolling bearing of a pressing plate on each side with a bearing slide rail of an adjacent edge is realized, so that continuous random adjustment of toughened glass of different size can be realized; a platform rotating shaft on one side is fixedly provided with a transmission gear, cooperation of the transmission gear with a corresponding manual gear is realized, the manual gear can be immobilized on a manual wheel shaft in a rotating manner, the inner end of the manual wheel shaft is provided with wheel shaft flanges, the wheel shaft flanges are immobilized on the outer side surface of a corresponding plate type rack, the outer end of the manual wheel shaft is provided with a shaft clamp spring, the shaft clamp spring is used for covering the outer side surface of the manual wheel shaft, a hand wheel step round part of the manual gear is fixedly connected with a hand wheel cross bar, and the outer end of the hand wheel step round part is provided with a hand wheel rocking handle; stabilization of toughened glass is achieved in the whole testing process via cooperation of screw bolt lockpins with lockpin support internal port threads.

Description

technical field [0001] The invention relates to a tempered glass inspection method, in particular to a tempered glass shard test and fixation method which can enlarge or reduce the four sides of the pressing plate and uses a reversible workbench to test the performance index of the glass. Background technique [0002] Fragmentation test is a main way to detect the quality of tempered glass. According to the requirements of national standards, after the 3mm thick tempered glass is broken, the fragments in any 50*50mm should be more than 30 pieces, and the 4mm~12mm thick tempered glass is broken. Fragments within any 50*50mm should be larger than 40 pieces, and a small amount of long fragments are allowed, the length of which should not exceed 75mm. The direction of the strip-shaped fragments should be roughly parallel to the edge of the glass. If they are not parallel, the included angle should not exceed 45 degrees. If one item fails to meet the standard, it is a substandard...

Problems solved by technology

This method is not only inconvenient to operate, it takes a long time, and the tape is a disposable product, which is easy to cause waste and pollution, and the tape residue on the test bench must be removed after each test to remove the broken glass, otherwise , the remaining glass fragments will affect the next experimental test operation

At the same time, the adhesive tape is also likely to be broken by the force of the tempered glass explosion, causing the operator to be injured. Therefore, it is very necessary to improve the tempered glass fragment test device

[0004] Chinese patent application number: 2009203050079, tempered glass falling ball test bench, in order to solve the problem of glass fragments splashing everywhere when tempered glass is used for experiments, the method of supporting frame box is adopted, although it can effectively remove glass fragments, it is inconvenient to read glass fragments , and the installa
