Titanium alloy fixing device with circular slide rail and four-side ball bearings in same plane

Abstract

The invention relates to a glass testing fixing device and provides a titanium alloy fixing device with a circular slide rail and four-side ball bearings in the same plane. The improvement is as follows: a stepped lower surface of a sliding plate part is a lower plane of a sliding plate; a circular groove is formed on the lower plane of the sliding plate; a centrosymmetric transition groove is arranged between the circular groove and the lower plane of the sliding plate; an upper surface of a fixing part is an upper fixing plane; a circular raised rail is arranged on the upper fixing plane; a centrosymmetric transition raised strip is arranged between the circular raised rail and the upper fixing plane; the lower plane of the sliding plate and the upper fixing plane are located at the same altitude; a fixing slope is arranged on the inner side of the upper fixing plane; a rubber pressing sheet is attached to the fixing slope; sliding ball bearings are fixed in ball base stepped holes on the lower plane of the sliding plate; the protruded spherical surfaces of the sliding ball bearings are in contact with the upper fixing plane, so that the sliding of the lower plane of the sliding plate in one fixing device relative to the upper fixing plane in the other fixing device is more smooth and easy, and the uneven stressing on the periphery of the tested armourplate glass is ensured.

Description

technical field [0001] The invention relates to a glass testing fixture, classification number: G01N3 / 04, in particular to such a titanium alloy fixture with sliding balls on four sides and the same plane on the same plane as the four sides of the circular rail slideway for testing the strength of glass, which can be enlarged or reduced in all directions. 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 glass objects, 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 ...

Problems solved by technology

This method is not only inconvenient to operate, but 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

[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 fixation 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 on the same plane superior

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.
