Accompanying drawing explanation
Fig. 1 is the structural representation of the device for exhaust manifold air-leakage test shown in the utility model preferred embodiment;
Mark and corresponding parts title in accompanying drawing: air-tightness detection device 100, gathering tube 101, arm 102, base 10, detection components 40, fixation kit 20, support 21, fixture 22, seal assembly 30, cylinder 31, expansion link 32, seal pad 33, air pump 41, surge tank 42, draft tube 43, tensimeter 44.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment 1
Refer to Fig. 1, air-tightness detection device 100 shown in the utility model preferred embodiment, described air-tightness detection device 100 is for the air-leakage test of exhaust manifold, and as shown in the figure, exhaust manifold is made up of gathering tube 101 and some arms 102 of being connected with described gathering tube 101.For the structure of exhaust manifold, devise the air-tightness detection device 100 being applicable to described exhaust manifold, comprise base 10, some fixation kits 20, some seal assemblies 30 and detection components 40.
The quantity of described fixation kit 20 is consistent with the mouth of pipe quantity of described exhaust manifold, the gathering tube 101 of exhaust manifold described in fixed clamp and described some arms 102 correspondingly, arbitrary fixation kit 20 comprises the fixture 22 that one end is fixed on the support 21 on base 10 and is fixed on described support 21, described fixture 22 can be used for clamping described gathering tube 101 or arm 102, and described exhaust manifold is fixed on described air-tightness detection device 100.
The quantity of described seal assembly 30 is consistent with the mouth of pipe quantity of described exhaust manifold, seal the mouth of pipe of described exhaust manifold correspondingly, arbitrary seal assembly 30 comprises the cylinder 31 be fixedly arranged on base 10, the expansion link 32 be connected with cylinder 31 and is fixedly arranged on the seal pad 33 of described expansion link 32 away from cylinder 31 one end, described cylinder 31 for drive described expansion link 32 stretch out/or shrink, described seal pad 33 is connected with the ferrule of described exhaust manifold, thus makes described exhaust manifold form an airtight cavity.Start cylinder 31, the expansion link 32 that is connected with cylinder 31 is driven to stretch out/or contractile motion, thus that the seal pad 33 being fixed on expansion link 32 one end is done relative to the exhaust manifold mouth of pipe of correspondence is close/or away from motion, thus to realize the sealing/of described exhaust manifold or the object of separating sealing.Be appreciated that one end of the contiguous described exhaust manifold mouth of pipe of described seal pad 33 is provided with a rubber layer (not shown), thus described seal pad 33 is sealed more closely with the described exhaust manifold mouth of pipe.
After the mouth of pipe of described exhaust manifold all seals, can start to carry out air-leakage test to described exhaust manifold.Described detection components 40 comprises air pump 41, surge tank 42, draft tube 43 and tensimeter 44.Described air pump 41 is all fixedly connected with described base 10 with described surge tank 42, and described air pump 41 is connected with described surge tank 42, and described air pump 41 is for inflating to described exhaust manifold.Described draft tube 43 one end is connected with described surge tank 42, and the other end is connected with described exhaust manifold through arbitrary seal pad 33, and described tensimeter 44 is arranged in described draft tube 43, for detecting the air pressure in described exhaust manifold.When starting to detect, booster air pump 41 produces pressed gas, after the gaseous tension fluctuation produced described air pump 41 through surge tank 42 cushions, to be entered in described exhaust manifold by described draft tube 43 thus realize the inflation to described exhaust manifold, in gas replenishment process, staff monitors described tensimeter 44 moment and closes air pump 41 to when reaching default upper pressure limit value, stop inflating described exhaust manifold, after the detection time through presetting, observe the numerical value of tensimeter 44, compare with the low pressure limit value preset again, if the force value that tensimeter 44 indicates is greater than or equal to preset pressure lower limit, then the air-leakage test of described exhaust manifold is qualified, if the force value that tensimeter 44 indicates is lower than preset pressure lower limit, then the air-leakage test of described exhaust manifold is defective.So, the air-leakage test to exhaust manifold is completed.
To sum up, air-tightness detection device 100 structure described in the utility model is simple, and easy to operate, testing result accuracy is high, easy to implement and popularization.
As mentioned above, the utility model can be realized preferably.
The above; it is only preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; according to technical spirit of the present utility model; within spirit of the present utility model and principle; the any simple amendment that above embodiment is done, equivalently replace and improve, within the protection domain all still belonging to technical solutions of the utility model.
