Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art can be by this specification
Disclosed content understands other advantages of the present utility model and effect easily.
As shown in Figure 1-Figure 3, a kind of water being applicable to aluminium alloy castings does not has leakage testing device, including the base plate for placing product 11
9, base plate 9 is provided with support column 3, the top of support column 3 is provided with fixed plate 2, and fixed plate 2 is provided with oil cylinder 1,
Oil cylinder 1 is provided with vertical piston rod 101, and the bottom of piston rod 101 is provided with pressing plate 5, and oil cylinder 1 is carried by piston rod 101
Dynamic pressure plate 5 moves up and down, and pressing plate 5 is provided with connecting rod 7, and the lower end of connecting rod 7 is provided with for blocking product eleven-punch
Resin plug 8, base plate 9 is equipped with for blocking the resin skin bottom product 11, the area of resin skin be more than product 11
Base area so that the bottom surface of product 11 is blocked completely, and resin micromicro is to be fixed on base plate by the mode such as adhesion, nail catcher
The upper surface of 9, prevents it to be subjected to displacement, affects plugging effect.The bottom of product 11 is pressed on resin under the effect of oil cylinder 1
Pi Shang, resin skin produces certain deformation, it is achieved the bottom gapless closure to product 11.Resin plug 8 can produce deformation,
When closure, product 11 will not be caused damage.Depression bar can also be set on pressing plate 5, be pressed on the upper surface of product 11, with
Connecting rod 7 coordinates, and product 11 is played good pressuring action.
In the present embodiment, the quantity of connecting rod 7 is 9, it is adaptable to JCB machine oil condenser shell, the position of connecting rod 7 is with cold
The position, hole of condenser shell upper surface is corresponding.When this device is for the leak test detection of other foundry goods, the quantity of connecting rod 7 and position
The position, hole of closure required with on product is corresponding.
The top of connecting rod 7 is equipped with spring 6, and connecting rod 7 is provided with for the lower end of spring 6 is carried out the first spacing chuck
71, the upper end of spring 6 is resisted against the lower surface of pressing plate 5, and connecting rod 7 is when the position, hole blocked on product 11, due to each hole
The height of position is different, and the length of each connecting rod 7 is also corresponding different, and the hardness of connecting rod 7 is higher, for rigid, pressing plate
5 when pressing to a certain height, some connecting rods 7 can plugging hole position completely, some connecting rods 7 may because of height tolerance,
The position, hole of product 11 upper surface can not be blocked completely, and then there is closure defect, it is possible that the phenomenon of local gas leakage, spring
6 is flexible, can produce certain deformation, play certain cushioning effect during stress, can be prevented effectively from the connecting rod 7 of rigidity
The situation of product eleven-punch cannot be blocked completely, even if part connecting rod 7 blocks the position, hole of correspondence the most completely, also have further
The space of compression so that the connecting rod 7 that another part blocks the most completely is pressed under continuing, it is achieved the closure completely of corresponding aperture position.

Being full of the mounting groove 81 coordinated, resin plug 8 is arranged on the lower end of connecting rod 7, this structure by mounting groove 81, mounting head 73
On the one hand assembling is simple, and on the other hand, Stability Analysis of Structures, resin plug 8 will not come off from mounting head 73.Mounting head 73
Structure is preferably cylinder, it is simple to install, and when its outward flange exceeds the edge 2-5mm of mounting groove 81, can realize optimal mistake
Cooperation of being full of blocks, if mounting head 73 is excessive, can burst mounting groove 81, if mounting head 73 is too small, then can not play good
Close-fitting effect, in some instances it may even be possible to there will be resin plug 8 and come off from mounting head 73.
The bottom of connecting rod 7 is provided with for the upper surface of resin plug 8 carries out the second spacing chuck 72, and connecting rod 7 is downward
Impulsive force relatively big, the second chuck 72 expands the lifting surface area of resin plug 8, and then reduces pressure, can be prevented effectively from because exerting oneself
Excessive and make mounting head 73 cause damage to bottom the mounting groove 81 of resin plug 8.
Being provided with vertical guide post 4 on pressing plate 5, the top of guide post 4 is located on the spacing hole of fixed plate 2, fixed plate 2
On spacing hole guide post 4 is played spacing effect so that guide post 4 can only move under in the vertical direction, therefore, pressure
Plate 5 also can only translate under in the vertical direction, and the position, hole of product 11 is sealed by the connecting rod 7 on pressing plate 5 in vertical direction
Stifled, improve the accuracy of closure, being prevented effectively from connecting rod 7 can not the situation of plugging hole position completely because of inclination.
Resin plug 8 and position, the hole interference fit of product 11, the lower limb of resin plug 8 is beyond the top edge of product eleven-punch
2-5mm, on the one hand this size realizes the closure completely to position, hole, it is to avoid locally implication, on the other hand, resin plug 8 will not
Deformation access aperture position cannot be passed through because of oversize.
Base plate 9 is provided with the passage 12 for ventilating the chamber of product 11, and passage 12 is connected to breather,
The gas of breather enters the chamber of product 11 by this passage 12.
The hardness of connecting rod 7 is preferably 38≤HRC≤42, and the material of resin plug 8 is preferably polyurethane, it is simple to draw materials, and becomes
This is relatively low, also meets the intensity required by producing and toughness.
The bottom of base plate 9 is provided with multiple bracers 10, and the bottom surface of a bracer 10 is in same level, it is achieved this device can
Smoothly to be laid on the table.
Work process of the present utility model is as follows: after product 11 is accurately placed on the resin skin of base plate 9, oil cylinder 1 promotes
Pressing plate 5 pan-down, the resin plug 8 of connecting rod 7 blocks in the corresponding hole site of product 11, after compressing product 11, logical
The trachea of device of air is connected to passage 12, inflates the chamber of product 11, after the pressure in chamber reaches setting value, stops
Stop-pass gas, submerges in pond by this device, i.e. observable gas leakage situation.
In sum, this utility model is applicable to all kinds of aluminium alloy castings, such as JCB machine oil condenser shell etc., it is achieved to holes of products
The closure completely of position, does not haves the phenomenon of local gas leakage, and plug can produce deformation, product will not be caused damage, operation side
Just, practical, hence it is evident that to improve work efficiency, the service life of extension fixture.
Above-described embodiment only illustrative principle of the present utility model and effect thereof, not for limiting this utility model.Any
