The standard used in device.
Background technology
In glass manufacturing process, due to the influence of the factor effect such as ambient temperature difference and mechanical force, there is one in glass
Fixed internal stress produces, if glass internal stress is extremely uneven, it will reduce the mechanical strength and heat endurance of glassware, shadow
The safe handling of product is rung, or even autoclasis phenomenon can occur.Internal stress in glass is nor completely unfavorable, in the system of glass
During making, appropriate control internal stress, the intensity of glass can be increased on the contrary, safety glass is exactly to improve using Quenching Treatment
One exemplary of glass machinery intensity, requirement of the specific glass kind to internal stress are more complicated.Therefore, measure in glass
Stress is a kind of means for controlling glass quality, and the particularly higher valuable or accurate product of quality requirement is even more important, and is controlled
Glass internal stress processed is just arisen at the historic moment firstly the need of its internal stress of accurate measurement, glass strain detector.As enterprise is to product
The attention of quality, magnitude tracing also it is more and more important get up, therefore the calibration of glass strain detector is also particularly important.
Existing calibrating mode is that standard test weight applies pulling force by rope to a level board, and normal glass is placed in level
On plate, normal glass is then blocked by support, and standard is conversed by the value of thrust of standard test weight and the sectional area of normal glass
Internal stress caused by glass, glass strain detector is measured normal glass now, to carry out school to glass strain detector
Problems be present in standard, existing this calibrating mode：Equivalent to one force application apparatus of standard test weight, level board are played to standard
Glass transmits the effect of power, and normal glass is in level board and the collective effect lower stress of support, the force direction of standard test weight
When there is deflection, level board and support can also produce deflection, force position of the standard test weight to normal glass to the power of normal glass
Put and the easy stress concentration of the contact position of normal glass and baffle plate, and cause normal glass frangible, in addition standard test weight
Continuous change value of thrust can not be provided, standard test weight and rope can only produce tension and can not produce compression in addition, to glass
The calibration of glass tension gauge is very limited.
The content of the invention
It is an object of the invention to provide a kind of glass strain detector calibrating installation, to solve in the prior art because of force
Caused by device force direction the problem of normal glass easy stress concentration fragmentation；The present invention also aims to provide one kind
The standard used in the glass strain detector calibrating installation.
In order to solve the above technical problems, the technical scheme of glass strain detector calibrating installation is as follows in the present invention：
Glass strain detector calibrating installation, including force application apparatus and standard, standard include normal glass and are arranged at mark
The connector at quasi- glass both ends, oscillating bearing, force application apparatus and wherein at least one oscillating bearing are provided with each connector
It is connected.
Connector be with the integrally formed glass-plate structure of normal glass, be provided with bearing mounting hole on connector, it is each to close
Bearings may be contained within corresponding bearing mounting hole.
Force application apparatus includes the electric force application mechanism of exportable pressure and is connected to electric force application mechanism and corresponding joint
Pull pressure sensor between bearing.
Connector has the changeover portion that is gradually reduced towards normal glass direction width, at the minimum widith of changeover portion with mark
The two sides of quasi- glass are connected smoothly.
The technical scheme of Plays device of the present invention is：
Glass strain detector calibrating installation standard, including normal glass and the connector for being arranged at normal glass both ends,
Oscillating bearing is provided with each connector.
Connector be with the integrally formed glass-plate structure of normal glass, be provided with bearing mounting hole on connector, it is each to close
Bearings may be contained within corresponding bearing mounting hole.
Connector has the changeover portion that is gradually reduced towards normal glass direction width, at the minimum widith of changeover portion with mark
The two sides of quasi- glass are connected smoothly.
Beneficial effects of the present invention are：In the present invention, force application apparatus by oscillating bearing to connector exert a force, power so by
Transmitting to normal glass, oscillating bearing itself has certain free degree, even if deflection occurs in the direction of force application apparatus power output
When, oscillating bearing can realize the release of stress by itself, will not be applied on normal glass, so as to avoid normal glass because
For the frangible problem of stress concentration caused by force application apparatus output force direction reason.
Further, connector is and the integrally formed glass-plate structure of normal glass, that is to say, that connector and standard
Glass can be cut by a monolithic glass and be formed, and the making of whole standard is simple and convenient.
Further, connector to changeover portion and changeover portion that during normal glass power transmission, width dimensions taper into
Being connected smoothly for normal glass can ensure that power transmission process is not easy stress concentration between connector and normal glass, further
Ensure that normal glass is non-friable.
