Arbitrary quadrilateral butadiene styrene rubber wheel corner fixed clamp

Abstract

The invention relates to a glass detection fixed clamp, and particularly relates to an arbitrary quadrilateral butadiene styrene rubber wheel corner fixed clamp. As the improvement, a rotary through hole is formed in a lower slippage plane; the other side of the rotary through hole is provided with a rotary table chamfering arc surface; the rotary table chamfering arc surface is located on a back plane of the lower slippage plane; a corner arc surface convex pointer is arranged on the rotary table chamfering arc surface; a step shaft pin is arranged on the other side of the rotary through hole; a wheel hole matching section is arranged on the step shaft pin; the outer end of the wheel hole matching section is a shaft pin outer end; a shaft pin screw hole is formed in the center of the shaft pin outer end; the outer circle of the wheel hole matching section is matched with a wheel inner hole in a rotatable manner; the shaft pin screw hole is matched with a wheel screw; a screw head of the wheel screw simultaneously shields a wheel step surface; a wheel slide groove is formed in one end of an upper clamping plane; a transition notch is formed between the wheel slide groove and the upper clamping plane; an anti-releasing groove is formed in a clamping inclined slope; an anti-releasing convex strip is arranged on a rubber pressing sheet; and the anti-releasing convex strip and the anti-releasing groove are in embedded type interference fit, so that quadrilateral glass with arbitrary included angles is fixed.

Description

technical field [0001] The invention relates to a glass testing fixture, in particular to such a styrene-butadiene rubber fixing fixture with any four sides of a wheel corner that can be zoomed in or out and used for testing the strength of glass. Background technique [0002] 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 certification certificate and have not been marked with China Compulsory Product Certification are not allowed to leave the factory. import and sale. [0003] Especially in ...

Problems solved by technology

Due to the diversity of automobile designs, the glass on the corresponding car is becoming more and more complex. The shape of the glass is often not square or rectangular, but parallelogram or trapezoidal. Uniform fixing fixtures can only use scotch tape paper or other methods to constrain the periphery of the glass, or cover a layer of film on the tempered glass to prevent glass fragments from splashing

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
