Titanium alloy wheel sliding groove four-edge controllable natural rubber clamps

Abstract

The invention relates to tempered glass testing clamps, in particular to titanium alloy wheel sliding groove four-edge controllable natural rubber clamps .As the improvement, the clamping part of each clamp comprises a clamp upper plane, a clamping slope and a vertical face gear, wherein a blind groove space is formed in the perpendicular portion of the clamp upper plane and the vertical face gear, and the clamping slope is provided with an anti-disengagement groove .A sliding framework on each clamp comprises a sliding lower plane and a sliding step face, the outer end of each wheel hole matched section is the outer end of a corresponding shaft pin, and a shaft pin screw hole is formed in the center of the outer end of each shaft pin .The outer ring of each sliding wheel is provided with a wheel I-shaped outer circle .The inner side of each sliding wheel is a wheel inner side face, a wheel inner hole is formed in each wheel inner side face, a wheel step hole is formed in each wheel outer side face, and a wheel step face is arranged between each wheel step hole and the corresponding wheel inner hole .The outer circle of each wheel hole matched section is rotationally matched with one wheel inner hole .Each wheel inner side face is attached to a corresponding shaft pin step .The sliding wheel of each clamp is in sliding fit with a wheel sliding groove of the adjacent clamp .A tempered glass plate can be continuously and freely adjusted.

Description

technical field [0001] The invention relates to a tempered glass test fixture, classification number: G01N3 / 04, in particular to such a four-sided controllable natural rubber fixture with a titanium alloy wheel chute that can be enlarged or reduced in four directions and used for testing the strength of glass. Background technique [0002] The existing tempered glass fragment test method is to place the tempered glass sample freely on the test bench, and use scotch tape paper or other methods to constrain the glass periphery, or cover the tempered glass with a film to prevent the glass fragments from splashing. On the center line of the longest side of the sample, at a position about 20mm away from the periphery, impact with a pointed hammer or punch with a tip curvature radius of 0.2mm±0.05mm to break the sample, within 20mm of the edge of the product and at the point of impact The number of fragments within a circle with a radius of 75 mm is not checked. Measures to pre...

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

[0003] 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: 201420595067.X, test device for tempered glass shards, proposed some new methods and measures to deal with brittle glass fixtures, but it is still impossible to adjust the size at will, and it is impossible to make the four sides of the retaining walls 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.
