Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is pressure-applying unit structural representation.
When Fig. 3 detects for utilizing the present invention to carry out glass plate bending resistance, by the schematic diagram of calculative determination scale mark 5.9 positions.
Embodiment
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
The bending resistance of glass plate shown in accompanying drawing pick-up unit, comprises base plate 1, lower support piece 2, debugging piece 3, column 4, pressure-applying unit 5, guide pillar 6, nut assembly 9 and installing plate 7; Base plate 1, column 4 and installing plate 7 are by the fastening formation framed structure of nut 8; Lower support piece 2 is a pair of, is fixed on base plate 1, is symmetric in the central axis of pressure-applying unit 5; Pressure-applying unit 5 is fixed on the center of installing plate 7 by nut assembly 9; Guide pillar 6 is lifted on installing plate 7, is symmetrically distributed in the both sides of pressure-applying unit 5 central axis; Debugging piece 3 is placed on lower support piece 2.
Pressure-applying unit 5 comprises briquetting 5.1, spring bottom plate 5.2, spring guide 5.3, leading rod 5.4, spring upper mounted plate 5.5, standard cushion block 5.6, spring 5.8 shaft couplings 5.10 and leading screw 5.12; Spring bottom plate 5.2, spring upper mounted plate 5.5, leading rod 5.4 form framed structure by hold-down nut 5.7; Standard cushion block 5.6 is placed between hold-down nut 5.7 and spring upper mounted plate 5.5; Leading screw 5.11 is connected with spring guide 5.3 by shaft coupling 5.10, and its lower end connects briquetting 5.1; On spring 5.8 suits and spring guide 5.3, be placed between spring bottom plate 5.2 and spring upper mounted plate 5.5; Handle 5.12 is equipped with on leading screw 5.11 tops; Leading rod 5.4 is provided with scale mark 5.9.
Position between scale mark 5.9 is determined by the specified bending strength of detected glass plate 10 of different size.
Calculate below by formula, determine the position of scale mark 5.9:
Glass plate bending strength formula: δ i=
Wherein: δ i---bending strength
P---bearing load
L---offset distance (lower support piece 2 centre distances)
B---detected glass plate 10 width
H---detected glass plate 10 thickness
P=
=KX X=
Wherein: K---the elastic coefficient
