Abstract

Disclosed is a measurement instrument using a trapezoidal aluminum alloy plate; wherein, rollers with the diameter larger than the thickness of the plate are arranged at two ends of the plate; circular holes are arranged in the center of the plate; a dial gauge is fixed on the aluminum alloy plate through a linkage apparatus; an end wheel of the linkage apparatus exposes outside the bottom face of the plate from the central hole of the aluminum alloy plate; the end wheel substitutes for a probe of the dial gauge, i.e., touching end wheel; then the dial gauge will have reading; when the aluminum alloy plate with the dial gauge arranged is placed on the toughened glass and rolls, the dial gauge will automatically read out the smoothness of the toughened glass, so the dial gauge can accurately measure the waveform of the toughened glass and timely control the product quality of the toughened glass, and greatly improve the optical distortion of the toughened glass, and solve the problem that the waveform of the toughened glass can not be accurately measured according to the national standard.

Description

The tempered glass waveform meter

Technical field

The utility model relates to a kind of tempered glass testing flatness instrument, belongs to the testing tool of building material field.

Background technology

Along with the day by day enhancing of people to comfortable, the safety of living environment, environmental protection, energy-conservation idea, tempered glass and be that former joint product has been widely used in various fields such as all kinds of building curtain walls, door and window, furniture, decoration and household electrical appliances with tempered glass.The manufacture craft of tempered glass is with behind the cutting of float glass process, the edging, puts into special-purpose electric furnace heating, when treating it near glass transition temperature, sends into the section of quenching immediately and cools off fast.The heat treated tempered glass of this process surface exists permanent compressive stress, so the physical strength of this glass is high.If tempered glass owing to reasons such as temperature improper, former sheet glass thickness tolerance of control and equipment, and causes final finished the waveform bending to occur in heat treatment process.This defective can cause the glass appearance out-of-flatness, produce optical distortion, influences attractive in appearance and result of use.

For the quality requirements of tempered glass waveform, stipulate in GB/T 9963-1998 " tempered glass " national standard: the tempered glass waveform should be no more than 0.3%, represents to the percent of the ratio of the distance of crest with trough to the height of crest with trough; Regulation in GB 17841-1999 " curtain wall with tempered glass and half tempered glass ": the maximal value of waveform mm/300mm is no more than 0.2%, measuring method is with the waveform place of a ruler near glass edge, record the height of trough or crest with clearance gauge, and represent the flexibility of waveform divided by the percent behind the 300mm.

Although above-mentioned two standards have been described the method for measuring the glass waveform in theory, bigger difficulty is arranged when actual measurement.Because the wave form varies value of tempered glass is very micro-, usually in 0.1mm～0.9mm scope.So small deflection is measured with conventional ruler, can not measure right value.

Summary of the invention

It is fast that the purpose of this utility model is to develop a kind of measuring speed, tempered glass waveform meter without the ruler measurement, this measuring instrument is with a trapezoidal aluminium alloy plate, the roller of slightly larger in diameter in plate thickness is equipped with at the two ends of plate, the length of aluminium alloy plate, according to adjacent warm-up mill track pitch in the tempering electric furnace from determining, the centre of plate has circular hole, one clock gauge is through a linkage, be fixed on the aluminium alloy plate, this linkage has end wheel to be exposed to outside the bottom surface of plate from the circular hole of aluminium alloy plate centre, and this end wheel replaces the probe of clock gauge, promptly touch the end wheel, clock gauge just has reading; Described linkage, be in a central shaft lower end, setting-in one end wheel, in the central shaft outside, overlap a sleeve pipe, central shaft pierces into another set of cylinder base, receiver is screwed on aluminium alloy plate, make in the circular hole on the end wheel slave plate of central shaft lower end and be exposed to outside the bottom surface of plate, the clock gauge gauge outfit is contained in the upper end of central shaft, and the probe position of clock gauge contacts with central shaft, like this, when this aluminium alloy plate that clock gauge is housed being placed on roll on the tempered glass, clock gauge just read automatically the tempering glass from flatness, can measure the waveform of tempered glass in process of production exactly, in time control the tempered glass product quality, improve the light distortion situation of tempered glass greatly, the situation of tempered glass waveform can't be accurately measured in solution according to national standard.
