Bearing slideway periphery same-plane-adjustable butadiene styrene rubber fixing device

Abstract

The invention relates to a glass testing device, and especially relates to a bearing slideway periphery same-plane-adjustable butadiene styrene rubber fixing device. The improvements of the fixing device are as follows: a sliding part is arranged on one end of a clamping part, the sliding part is overlapped on the upper surface of the clamping part; the lower surface of the sliding part is taken as the sliding lower plane, the sliding lower plane is provided with rolling bearing, a bearing pin shaft is arranged between the rolling bearing and the sliding lower plane; furthermore, a transition groove is arranged between a bearing slideway and a clamping upper plane; the bottom of the bearing slideway is provided with a blind groove space; moreover, one end of the bearing slideway is opened; the external end of the bearing pin shaft is provided with an opened pin for shaft to stop the rolling bearing, the opened pin for shaft is arranged in the blind groove space, a gap between the opened pin for shaft and the blind groove space; the sliding lower plane and the clamping upper plane are in the same height; the inner side of the clamping part is provided with a clamping slope, rubber press sheets are adhered on the clamping slope; sliding cooperation exists between the rolling bearing of each press plate and neighbored bearing slideway, and the random and continuous adjustment on tempered glass plate with different widths can be achieved.

Description

technical field [0001] The invention relates to a glass testing device, classification number: G01N3 / 04, in particular to such a styrene-butadiene rubber fixing device which can be enlarged or reduced around and used for testing the strength of glass. Background technique [0002] Glass is one of the oldest materials discovered and utilized by man. As early as 3,500 years ago, ancient Egypt had the technology of making simple glassware, and in the tombs of the Western Zhou Dynasty in my country, man-made glass ornaments were also unearthed. With the development of science and technology, glass has developed particularly rapidly in the past one hundred years, and glass has become an indispensable material in human daily life. With the development of economy, the application of glass in all walks of life is more and more extensive. Glass can be used as glass curtain walls, glass doors and windows, etc. in buildings, as teacups, wine bottles, lamps, etc. in consumer goo...

Problems solved by technology

This method is not only inconvenient to operate, but takes a long time, and the adhesive tape is a disposable product, which is easy to cause waste and pollution, and after each test, the adhesive tape residue on the test bench plate 50 must be removed to clean up the broken glass. Otherwise, the remaining glass fragments will affect the next experimental test operation

[0006]At the same time, the adhesive tape may also be broken by the force of the tempered glass explosion, causing the operator to be injured. Therefore, it is necessary to improve the tempered glass fragment test device

[0007] Chinese patent application number: 201420595067.X, test device for tempered glass shards, proposed some new methods and measures to deal with the clamping 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 platen 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.
