Hydraulic platen thread lock pin styrene-butadiene rubber wheel press plate glass test system

Abstract

The invention relates to a tempered glass testing and inspecting device, particularly to a glass testing system adopting a hydraulic platen, threaded lock pins and styrene butadiene rubber wheel pressure plates, and the improvement lies in that: a hydraulic stretching cylinder adopting the structure cooperates with a T-shaped guide rail to drive the testing platen to be overturned, so that chunk glass can be removed conveniently; through the threaded fit of stud lock pins and inner holes of lock pin supports, cylindrical bulbs at the end parts of the stud lock pins enter the spiral taper lock holes in the two sides of the testing platen, so as to be locked and located, and the defect that self-locking is unavailable for cooperation of a traditional transmission gear and a manual gear, as a result, the entire tempered glass plate is kept stable and solid during testing. According to the invention, two parts, namely an upper short pulley and a lower long pulley both arranged on the hydraulic stretching cylinder together control the T-shaped guide rail to swing by taking the platen rotating shaft as a center, and together control a T-shaped rail cross plate on the T-shaped guide rail to roll in a sliding manner; besides, the device adopting the structure avoids the error generated between rectilinear motion by a hydraulic piston rod and swing motion by the testing platen.

Description

technical field [0001] The invention relates to a test and inspection device for tempered glass, classification number: G01N3 / 32, in particular to such a pressure plate that can be enlarged or reduced around, and uses a reversible workbench to test the strength of the glass. Rubber wheel platen glass test system. Background technique [0002] With the development of economy, the application of glass in all walks of life is more and more extensive. At present, many important glass components, such as large-scale glass curtain walls and glass zeniths, and windshield glass of aerospace vehicles are made of special glass such as toughened glass, which has very strict requirements on glass performance, so it is becoming more and more important to test the performance of glass . Since May 1, 2003, my country has implemented a mandatory inspection system for safety glass used in automobiles, trains, and buildings. Safety glass products that have not obtained a compulsory product ...

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

[0005] 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

[0006] Chinese patent application number: 2009203050079, tempered glass falling ball test bench, in order to solve the problem of glass fragments splashing everywhere when the tempered glass is tested, the method of supporting the frame box is adopted. Although the glass fragments can be effectively removed, it is inconvenient to read the glass fragments , and the installation efficiency of continuous multi-piece tempered glass is low

[0007] Another Chinese patent application number: 201420595067.X, the test device for tempered glass shards, proposed some new methods and measures to deal with the pressure plate of brittle glass, but it is still impossible to adjust the size at will, and it is impossible to make the four sides of the pressure plate all in the same on flat surface

At least one side of the patent must not be in contact with the test bench surface

What is referred to as the suspended retaining wall 5 in the embodiment cannot be in contact with the base 1 simultaneously with other three-sided retaining walls, so the retaining piece 4 has to be used to make up the gap between the suspended retaining wall 5 and the base 1, resulting in four Uneven surrounding force

In addition, the width of the baffle 4 itself is fixed, and only multi-piece splicing can be used, and continuous changes of different widths cannot be achieved.
