Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, make to retouch the most in detail to detailed description of the invention of the present utility model
State.Following example are used for illustrating this utility model, but can not be used for limiting scope of the present utility model.
As it is shown in figure 1, the products air tightness detection tool of this utility model embodiment includes: be oppositely arranged
Upper bolster 1 and die shoe 2, and ventilation assembly.
The lower surface of upper bolster 1 is provided with pressing plate 3, and the upper surface of die shoe 2 is provided with sealing plate 4, pressure
It is used between plate 3 and sealing plate 4 placing product 100 to be measured, when upper bolster 1 moves downward, can will treat
Survey product 100 to be clamped between pressing plate 3 and sealing plate 4, now sealing plate 4 and product 100 to be measured it
Between can form gas die cavity 101.
Ventilation assembly includes that the air inlet pipe 5 connected with sealing plate 4 and the digital display pressure in air inlet pipe 5 are opened
Pass 6 and manostat 8, offer air inlet 7, the inlet end of air inlet pipe 5 and air inlet on sealing plate 4
Whether 7 connections, be that penetrability is split with the crackle detected on product 100 to be measured to gas die cavity 101 supply
Stricture of vagina, and judge whether product 100 to be measured can meet waterproof or air-tightness requirement.
In the present embodiment, the lower surface of upper bolster 1 is provided with guide pillar 9, and the upper surface of die shoe 2 is arranged
There are guide pin bushing 10, guide pin bushing 10 and guide pillar 9 inserting to connect, and the upper surface of upper bolster 1 is provided with upper mold foot
12, the lower surface of die shoe 2 is provided with lower mold foot 13, and such upper bolster 1 can be at guide pin bushing 10 and guide pillar 9
Move up and down under the guide effect of inserting.
In order to prevent weighing product 100 to be measured wounded, upper bolster 1 lower surface is provided with limited post 11, this limit
Position post 11 is for limiting the stroke of upper bolster 1.
During operation, first detection tool is fixed on the device of similar punch press, it is ensured that gaseous type intracavity is logical
After entering certain pressure gas, tool will not separate；Then manostat is adjusted, it is ensured that in insufflation gas die cavity
