Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of cylindrical battery sealing air-tightness detection device comprises tensimeter 8, high-pressure air pipe joint 1, draw point 2, worktable 7, battery clamp, cylinder 11, and it is characterized in that: described tensimeter 8 is connected with high-pressure air pipe joint 1 by pipeline; Described battery clamp comprises strap 4, mobile clamping plate 9, guide rail 5, silicagel pad 3; The inner concave that is fixed in the strap 4 on the worktable 7 is provided with silicagel pad 3, high-pressure air pipe joint 1 is housed on the strap 4, a hole that is complementary with draw point is set at the middle part of described strap 4, draw point 2 and described high-pressure air pipe joint 1 seamless link, and place and pass silicagel pad 3 in the hole; Pass through guide rail 5 fixed guide between strap 4, the mobile clamping plate 9; Be provided with cylinder 11 on the worktable 7, the push rod 10 on the cylinder 11 is fixed in the outside of mobile clamping plate 9.
Using method and principle of work
When the utility model is used for the detection of cylindrical battery sealing impermeability, at first the middle part of detected cylindrical battery 6 cylinders is bored the aperture of a ￠ 2.0mm～3.0mm, battery 6 is put into battery clamp, the aperture of battery is aimed at draw point 2, draw point 2 external diameter ￠ 1.5mm～2.5mm, internal diameter ￠ 1.0mm～2.0mm, draw point 2 is inserted in battery 6 apertures, battery 6 is close to silicagel pad 3, then the push rod by cylinder 11 10 promotes mobile clamping plate 94 direction advances along guide rail 5 to strap, make battery 6 and silicagel pad 3 close proximity, battery 6 is advancing to the position and fixes.This moment, topped up with water on battery cap was opened high pressure gas again, and high pressure gas is injected to cylindrical battery 6 through high-pressure air pipe joint 1, draw point 2, slowly pressurization, whether whether have Bubble formation, and observe the force value of tensimeter 8 if observing battery cap sealing sealing place, leak gas thereby detect battery.After detection is finished, cylinder 11 pressure releases, the mobile clamping plate 9 of push rod 10 pullings on the cylinder 11 restore, and the battery 6 that has detected is taken out.
