Abstract
The utility model relates to an element airtightness detection apparatus, particularly to an aluminium casting airtightness detection apparatus which includes a detecting bench and a pedestal disposed thereon. The upper surface of the pedestal is provided with a matching surface which matches with a sealed connection surface of an aluminium casting. A hydraulic push rod for pushing a connecting screw hole of the aluminium casting is arranged above the pedestal. The pedestal is provided with a vent hole which corresponds to a cavity of the aluminium casting and is connected to a compressor by a vent pipe. The vent pipe is connected to a magnetic valve and a barometer in series. By employing the airtight detection apparatus, the airtight can be tested quickly and the airtight level can be tested quantitatively.
Description
Technical field
The utility model relates to a kind of part air tightness detection apparatus, particularly a kind of aluminium casting air tightness detection apparatus.
Background technology
At present, in prior art, aluminium casting is often used in the parts such as hydraulic valve, hydraulic pump body and the car engine engine housing of seal request, its blow hole, the defect such as loose can cause seepage, and therefore foundry goods, dispatching from the factory and assembling before use, all needs to carry out air-tight test.
Enterprise adopts water seaoning inspection mostly now, and its concrete operation step is as follows: by putting into water after aluminium casting sealing, to aluminium casting inner chamber injecting compressed air, produce angry bubble if defectiveness just has gas permeation.This test mode can not be tested minor leakage, can not judge the severity of seepage, estimates judgement in addition also easily cause erroneous judgement by people.Be unfavorable for the check of typical products in mass production simultaneously.
utility model content
The technical problems to be solved in the utility model is: provide a kind of detection speed fast, can quantitatively detect the air-tightness detection device of sealed horizontal.
In order to solve the problems of the technologies described above, the utility model provides a kind of aluminium casting air-tightness detection device, include monitor station, and be arranged on the pedestal on monitor station, pedestal upper surface is provided with the mating surface matching with the aluminium casting face of being tightly connected, and pedestal top is provided with the hydraulic mandril of extruded aluminium foundry goods connecting screw hole, is provided with the air hole corresponding with aluminium casting cavity on described pedestal, air hole is connected on compressor by snorkel, is serially connected with solenoid valve and rain glass on snorkel.
Adopt the aluminium casting air-tightness detection device tool of technique scheme to have the following advantages: because aluminium casting is placed on the pedestal of monitor station, pedestal upper surface is provided with the mating surface matching with the aluminium casting face of being tightly connected, and the hydraulic mandril that pedestal top arranges corresponding aluminium casting connecting screw hole respectively, push and simulate bolt Quick fastening aluminium casting, thereby impermeability is detected can start as early as possible, the outlet of compressor is connected to by snorkel on the air hole of pedestal, air hole is corresponding with aluminium casting cavity, after inflation, solenoid valve can fast shut-off snorkel, now rain glass detects the variation of aluminium casting air pressure inside, thereby judge the impermeability of aluminium casting.
As preferred version, in order to guarantee the intensity of snorkel, extend its serviceable life, described snorkel is metal tube.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment aluminium casting location cleaning device.
embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
As shown in Figure 1, the utility model provides a kind of aluminium casting air-tightness detection device, include monitor station 1, and be arranged on the pedestal 2 on monitor station 1, pedestal 2 upper surfaces are provided with the mating surface matching with aluminium casting 3 faces of being tightly connected, pedestal 2 tops are provided with the hydraulic mandril 4 of extruded aluminium foundry goods 3 connecting screw holes, on described pedestal 2, be provided with the air hole corresponding with aluminium casting 3 cavitys, air hole is connected on compressor 6 by snorkel 5, on snorkel 5, be serially connected with solenoid valve 7 and rain glass 8, in order to guarantee the intensity of snorkel 5, extend its serviceable life, snorkel 5 adopts metal tube.
Use is, aluminium casting 3 is placed on the pedestal 2 of monitor station 1, pedestal 2 upper surfaces are provided with the mating surface matching with aluminium casting 3 faces of being tightly connected, and hydraulic mandril 4 connecting screw hole of corresponding aluminium casting 3 respectively that pedestal 2 tops arrange, push and simulate bolt Quick fastening aluminium casting 3, thereby impermeability is detected can start as early as possible, the outlet of compressor 6 is connected to by snorkel 5 on the air hole of pedestal 2, air hole is corresponding with aluminium casting 3 cavitys, after inflation, solenoid valve 7 can fast shut-off snorkel 5, now rain glass 8 detects aluminium casting 3 air pressure inside variations, thereby judge the impermeability of aluminium casting 3.
Above-described is only one of preferred implementation of the present utility model; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model principle; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
