Fig. 1 is the top view of prior art charge air cooler housing.
Fig. 2 is the upward view of prior art charge air cooler housing.
Fig. 3 is the structural representation of this utility model charge air cooler air-tightness detection device of shell body.
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.
Detailed description of the invention
Fig. 1 is the top view of prior art charge air cooler housing；Fig. 2 is the upward view of prior art charge air cooler housing；In figure, 10 is body, and 12 is cavity, and 14 is outthrust, and 16 is edge.Fig. 3 is the structural representation of this utility model charge air cooler air-tightness detection device of shell body；In figure, 20 is water tank, and 21 is water pump, and 30 is positioning fixture, 31 is boss, and 32 is telescopic cylinder, and 33 is pressing lever, 34 is limited block, and 35 is breach, and 36 is resilient rubbber cushion, 37 is elastic rubber ring, and 310 is venthole, and 320 is locating shaft, 330 is pressure head, and 331 is gum elastic set, and 40 is air compressor machine, 41 is loading line, and 50 for controlling switch.
Seeing also Fig. 1 to Fig. 3, charge air cooler air-tightness detection device of shell body includes water tank 20, positioning fixture 30 and air compressor machine 40.Positioning fixture 30 is arranged at water tank 20 top, positioning fixture 30 includes positioning boss 31, telescopic cylinder 32 and at least two pressing levers being oppositely arranged 33, telescopic cylinder 32 is tiltedly arranged at the side of positioning boss 31, and pressing lever 33 is vertically arranged at top the edge 16 of corresponding charge air cooler housing of positioning boss 31.The mating shapes of the cavity 12 of the shape of positioning boss 31 and charge air cooler housing.The size of positioning boss 31 is little compared with the cavity 12 of charge air cooler housing.The end of telescopic cylinder 32 is provided with the locating shaft 320 of cylinder, and the shapes and sizes of locating shaft 320 match with the cylindric outthrust 14 of charge air cooler housing.Positioning boss 31 upper surface is provided with the venthole 310 being connected with loading line road, and air compressor machine 40 is connected with loading line 41, and connecting in loading line 41 has Pressure gauge.
Water tank 20 is provided with water inlet and outlet, and water inlet is connected with water pump 21.Charge air cooler air-tightness detection device of shell body also includes controlling switch 50, control switch 50 be arranged at the front side of water tank 20 and electrically connect with water pump 21 and air compressor machine 40, control switch 50 and be used for controlling water pump 21 water filling and inflating to loading line 41 for controlling air compressor machine 40 in water tank 20.
Positioning fixture 30 also includes at least two limited block 34, and the corresponding pressing lever 33 of limited block 34 is arranged at the surrounding of positioning boss 31, and limited block 34 is provided with the semicircular breach 35 that the pressure head 330 with pressing lever 33 matches.The pressure head 330 of pressing lever 33 is provided with gum elastic set 331, and breach 35 is provided with resilient rubbber cushion 36.Pressing lever 33 is connected with driving cylinder, is pressed for 33 times by driving air cylinder driven pressing lever.Positioning boss 31 edge 16 is provided with elastic rubber ring 37, and elastic rubber ring 37 coordinates with the edge 16 of charge air cooler housing.Owing to being provided with gum elastic set 331, resilient rubbber cushion 36 and elastic rubber ring 37, therefore cushioning effect can be played when 33 times pressures of pressing lever, prevent centering cooler shell body from causing damage.Elastic rubber ring 37 also seals, and prevents the water and air of outside from entering in the cavity of charge air cooler housing.
During use, first charge air cooler housing is positioned on positioning boss 31, the cavity 12 making charge air cooler housing coordinates location with positioning boss 31, cylindric outthrust 14 coordinates location with locating shaft 320, drive the edge 16 of 330 times pressure charge air cooler housings of pressure head of air cylinder driven pressing lever 33, the most just complete the location of centering cooler shell body.Then, by loading line, air compressor machine and air-filled pore insufflation gas, observe whether Pressure gauge changes, if unchanged, illustrate that air-tightness meets requirement, otherwise, illustrate that air-tightness can not meet requirement.If being unsatisfactory for air-tightness requirement, then open water pump 21, water pump 21 water filling in water tank 20 by control switch 50.After water floods charge air cooler housing completely, open air compressor machine 40 again, owing to the volume of positioning boss 31 is less than the size of cavity, therefore leave space between the body 10 of positioning boss 31 and charge air cooler housing.Air compressor machine 40 is inflated in this space of charge air cooler housing by loading line 41.Now, emerge if having on the body 10 of bubble therefrom cooler shell body, then prove that this charge air cooler housing exists sand holes defect and can determine that its position.Thus, charge air cooler housing air-leakage test can just be completed.
This utility model charge air cooler air-tightness detection device of shell body provides the benefit that and can position with centering cooler shell body and seal, to carry out air-leakage test；Further, after being found to have sand holes or crackle, detection sand holes or crackle particular location further.
