Abstract
The invention discloses a detection device for glass surface stress. The detection device comprises a support, a supporting plate, a cylinder and a compact type surface stress gauge. The cylinder is fixed above the support and is arranged on the supporting plate below the support through a U-shaped connecting rod in connecting and driving modes. The supporting plate is placed over a sample conveying device, the compact type surface stress gauge is fixed downwards in the middle of the supporting plate, and the lower surface of the supporting plate is provided with a plurality of vacuum suction cups for sucking samples. The detection device for glass surface stress is high in precision, small in error in the measuring process, simple in structure, convenient to mount, capable of conducting measuring conveniently, low in manufacturing cost, convenient to use, and wide in applicability.
Description
Technical field
The present invention relates to a kind of stress detection device, particularly a kind of glass surface stress detection device.
Background technology
Due to the singularity of production technology, in the glassware after completing, also there is internal stress more or less.In glass forming process, due to external mechanical force effect or cooling time heat uneven produced stress be called thermal stress or macro-stress.At inside glass, the stress that the micro-uneven district formed due to uneven components causes is called structural stress or microstress.Stress existing in the volume range being equivalent to unit cell dimension in glass is called ultramicroscopic view stress.Due to the architectural characteristic of glass, microcosmic wherein and ultramicroscopic view stress minimum, little on the impact of the physical strength of glass.What have the greatest impact is thermal stress in glass, because this stress is normally extremely uneven, can reduces physical strength and the thermal stability of glassware, affect the safe handling of goods, even autoclasis phenomenon can occur time serious.Therefore, in order to ensure safety when using, various glassware is all specified that the internal stress of its remnants can not exceed a certain setting.For optical glass, the existence of larger stress will have a strong impact on light transmission and image quality.Therefore, the internal stress measuring glass is a kind of means of Mass Control, particularly the product of the valuable or precision that quality requirements is higher is even more important, take place frequently due to earthquake disaster, the glazing in urban high buildings and large mansions, apartment all can use safety glass, do not have clear and definite specification about safety glass for building, former analyzer sensitivity is very low, is difficult to carry out sufficient qualitative control.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of structure simple, the glass surface stress detection device that measuring accuracy is high.
The present invention in order to the technical scheme solving its technical matters and adopt is: a kind of glass surface stress detection device, comprise support, back up pad, cylinder and compact surface stress instrument, described cylinder is fixed on above support, and the back up pad driving and be located at below support is connected by U-shaped connecting rod, described back up pad is positioned at directly over sample delivery device, described compact surface stress instrument is fixed in the middle of back up pad downwards, and back up pad lower surface is provided with the vacuum cup of several adsorption samples.
As a further improvement on the present invention, described back up pad is square, and described back up pad lower surface is provided with 4 vacuum cups, and described 4 vacuum cups are located at the side, 4 angles of quadrate support plate respectively.
The invention has the beneficial effects as follows: glass surface of the present invention answers power apparatus precision high, and error during measurement is little, and apparatus of the present invention structure is simple, install and measure conveniently, cost of manufacture is cheap, easy to use, and applicability is wide.
