Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of assembly.
Embodiment
Below with reference to the accompanying drawings and the invention will be further described in conjunction with the embodiments.
The bending resistance of glass plate shown in accompanying drawing pick-up unit, comprise base plate 1, lower support block 2, debugging block 3, column 4, assembly 5, from guide rod 6, nut assembly 9 and installing plate 7; Base plate 1, column 4 and installing plate 7 is by the fastening formation framed structure I of nut 8; Lower support block 2 is a pair, is fixed on base plate 1, is symmetric in the center of assembly 5; Assembly 5 is fixed on the center of installing plate 7 by nut assembly 9; Be lifted on installing plate 7 from guide rod 6, be symmetrically distributed in the both sides of assembly 5; Debugging block 3 is placed on lower support block 2.
Assembly 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 coupling 5.10 and leading screw 5.11; Spring bottom plate 5.2, spring upper mounted plate 5.5, leading rod 5.4 form framed structure II 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; Spring 5.8 is set with on spring guide 5.3, is 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 top; 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 the glass plate of different size.
Below by formulae discovery, 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 (on glass blocks two rest pad centre distance)
B---width of glass sheet
H---sheet thickness
P=
=KXX=
Wherein: K---the elastic coefficient
The displacement of X---spring-compressed
δS=X-S=
-S
Wherein: S---standard pad thickness
Actual compression displacement when δ S---detects, and the position of scale mark 5.9
During operation, apply preload pressure first to spring 5.8, spring 5.8 compresses S distance in advance, two lower support blocks 2 are adjusted according to detection glass, distance L, debugging block 3 is placed on back-up block 2, turn clockwise handle 5.12, assembly 1 touches debugging block 3 along being moved downward to briquetting 5.1 from guide rod 6, continue the handle 5.12 that turns clockwise, spring upper mounted plate 5.5 is along from guide rod 6, leading rod 5.4 moves down, Compress Spring 5.8, hold-down nut 5.7 and spring upper mounted plate 5.5 gap increase simultaneously, the standard cushion block 5.6 chosen is inserted wherein, be rotated counterclockwise handle 5.12 to briquetting 5.1 and leave debugging block 3.
Detection glass plate is placed on two lower support blocks 2, turn clockwise handle 5.12, assembly 5 moves down along from guide rod 6, detection glass plate is touched to briquetting 5.1, continue the handle 5.12 that turns clockwise, spring upper mounted plate 5.5 moves down Compress Spring 5.8 along from guide rod 6, leading rod 5.4, mobile δ S distance reaches scale mark 5.9, after spring upper mounted plate 5.5 moves to scale mark 5.9, glass plate is intact, can judge that glass plate bending strength is qualified, otherwise glass plate is broken in spring 5.8 compression process.
