Embodiment
Referring to figs. 1 through Fig. 6, the specific embodiment of a kind of convenient air tightness detection equipment observed of the utility model is described further.
A kind of convenient air tightness detection equipment observed, as shown in Figure 3 and Figure 4, comprise frame 4, described frame 4 is provided with worktable 2, worktable 2 is provided with the feeder detected for inputting source of the gas to part 1, feeder comprises air pump 6 and conduit 5, worktable 2 is provided with ventilating column 9, ventilating column 9 is offered with through hole for ventilation, the upper end of ventilating column 9 is output terminal 11, inner for putting in part 1, the following side of ventilating column 9 offers transverse side holes as air admission hole 10, air admission hole 10 is for being tightly connected with one end of conduit 5, be set-located and form tight grafting, the other end and the air pump 6 of conduit 5 link together, it is inner that gas is inputted part 1 by conduit 5 and ventilating column 9 by such air pump 6 endlessly, the hold down gag 7 for compressing component 1 is provided with above worktable 2, as shown in Figure 5, hold down gag 7 comprises the support member by cylinder-driven, support member is made up of cylindrical cast iron, above worktable, part 1 conflict is squeezed in worktable 2 by the transmission of cylinder to be fixed, thus prevents part 1 from shaking in testing process, the packoff 8 for obturator 1 is provided with in the side of worktable 2, packoff 8 comprises the seal 12 by cylinder-driven, the shape of seal 12 is identical with the shape of part 1 other end through hole, sealing function is formed by the through hole of seal 12 grafting part 1 like this by cylinder-driven, certainly comparatively preferably, seal 12 is also arranged with packing washer 14, packing washer 14 is rubber band, as shown in Figure 6, time like this in the through hole of seal 12 grafting part 1, the through hole of rubber band and part 1 end is formed conflicts, increase the sealing that seal 12 blocks through hole, in such guarantee testing process, part 1 can not form bubble in through hole, and be provided with for stretching into the convenient water tank 3 observing part 1 sealing for worktable 2 below worktable 2, water tank is made up of transparent material, can be that glass or transparent plastic material are made, water is contained with in water tank 3, active cylinder is connected with in water tank 3 end, active cylinder transmission makes water tank 3 rise, such worktable 2 and part 1 will be imbedded in water gradually, active cylinder transmission water tank 3 is set like this and can prevents spray, can to ensure in testing process that part 1 enters in water to carry out detection and make to produce sputtering phenomenon, and when part 1 detects in water, whether bubble can be produced by comprehensive observation part outside water tank 3, small bubble also can easily be observed efficiently, which improves detection efficiency.
In use, first the through hole of one end of part 1 is plugged on ventilating column 9, then by cylinder-driven, seal 12 is got lodged in the through hole formation sealing of part 1 other end, now in the upper end of part 1, part 1 is fixed compressing member conflict by cylinder-driven again, and then by cylinder 10 transmission water tank 3 to be raised worktable complete 2 is immersed in the water entirely, such part 1 is just immersed in water and has suffered, now air pump 6 is given in the through hole of part 1 and is inputted gas, so just can observe in water tank 3 and whether have bubble generation to detect the impermeability of part 1, certainly comparatively preferably on worktable 2, some ventilating columns 9 are provided with, some parts 1 can be detected so simultaneously, improve detection efficiency, comparatively preferably, worktable 2 is also provided with fixed leg 13, the shape of fixed leg 13 is in this no limit, determine according to the shape of concrete part 1, for part 1 better being fixed, prevent to rock, so just can better detect the impermeability of part 1, below just reach and part 1 is transferred in water tank 3 by active cylinder, then to its air feed, observe it and whether can produce bubble, whether the hermetic seal that conveniently can detect part 1 is qualified, such detection efficiency is high, and does not need manual detection, reduces testing cost.
