Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The strength test device as shown in Figure 1, a kind of dumbbell pin dispatches from the factory, makes a strength test to dumbbell pin 12, the dumbbell
Pin includes cylinder 13 and the end 14 for being fixed on both ends, should include upper tire 1 and lower tire 2, and the upper tire 1 includes snap-gauge I3, guide rod 4
With top board 5, the both ends of the snap-gauge I3 are fixed with guide rod 4, and the guide rod 4 connects snap-gauge I3 and top board 5, the lower tire 2
Including snap-gauge II6, side plate 7 and lower platen 8, the both ends the snap-gauge II6 are fixed with side plate 7, the side plate 7 connect snap-gauge II6 and
Lower platen 8 offers guide hole 9 on the snap-gauge II6, and the position of the guide hole 9 is corresponding with guide rod 4, and the guide rod 4 passes through guide hole
9, the snap-gauge I3 being connected with guide rod 4 are in the space that snap-gauge II6, side plate 7 and lower platen 8 are formed, and the snap-gauge I3 is opened up
There is circular hole I10, circular hole II11 is opened on the snap-gauge II6, the circular hole II11 is coaxial with circular hole I10 and diameter is equal, the circle
The diameter of hole I10 and circular hole II11 are less than the diameter of end 14 and are greater than the diameter of cylinder 13.
As shown in Figures 2 and 3, square groove I21, the snap-gauge are also provided in the long side of the side of snap-gauge I3 described in the present embodiment
Offer square groove II22 in II6 and snap-gauge I3 same side, the square groove I21 and square groove II22 is coaxial and side length is equal is described
Square groove I21 is connected to circular hole I10, and the square groove II22 is connected to circular hole II11, and the side length of the square groove I21 and square groove II22 are big
In the diameter of cylinder, the purpose that square groove I21 and square groove II22 is arranged is that dumbbell pin 12 can be by square groove I21 and square groove II22
Into in circular hole I10 and circular hole II11.
Wherein, the effect of snap-gauge I and snap-gauge II is to block two ends 14 of dumbbell pin 12, circular hole I10 and circular hole
The effect of II11 is to combine the cylinder merging of dumbbell pin 12 wherein, and top board 5 is connected to press machine, lower platen 8
It is placed on the ground, guide rod 4 can slide in guide hole 9, while play a part of to connect snap-gauge I3 and top board 5, work as press machine
To top board 5 apply pressure, lower platen 9 be placed on the ground it is immovable, then top board 5 and lower platen 9 do distance reduce
Relative motion, at this point, the snap-gauge I3 and snap-gauge II6 that are connected with top board 5 and lower platen 9 then do the relative motion that distance increases,
The dumbbell pin being stuck on snap-gauge I3 and snap-gauge II6 then hinders this relative motion, then dumbbell pin 12 is by from snap-gauge I3 and card
The pulling force of plate II6, due to snap-gauge I3 connection top board 5, snap-gauge II6 connection lower platen 9, then pulling force size suffered by dumbbell pin 12
Equal with the pressure size that 5 press machine of top board applies, the pressure value read from the dial gauge in press machine is to the present apparatus
To the value for the pulling force that dumbbell pin 12 is applied, it is possible thereby to accurately measure the size of pulling force suffered by dumbbell pin 12.
