Accompanying drawing explanation
By reading the detailed description done non-limiting example with reference to the following drawings, other features, objects and advantages of the present invention will become more obvious:
Fig. 1 is the structural representation of a kind of vehicle part air-tightness detection device of the present invention;
In figure: the right hydraulic cylinder of 1-pedestal, 2-, 3-electric pneumatic source, 4-seal head, 5-holder, 6-magnet, 7-piston rod, 8-air-pressure duct, 9-tracheae, 10-air-pressure chamber, 11-barometer, 12-left hydraulic cylinder.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
Refer to Fig. 1, the invention provides a kind of technical scheme: a kind of vehicle part air-tightness detection device, comprise pedestal 1 and air-pressure chamber 10, pedestal 1 upper right position is provided with right hydraulic cylinder 2, right hydraulic cylinder 2 is fixed by bolt and pedestal 1, right hydraulic cylinder 2 top position is provided with electric pneumatic source 3, can support to work long hours as a stable pneumatic supply in electric pneumatic source 3, electric pneumatic source 3 is fixed by bolt and right hydraulic cylinder 2, right hydraulic cylinder 2 leftward position is provided with piston rod 7, seal head 4 is provided with bottom piston rod 7, piston rod 7 inside is provided with air-pressure duct 8, air-pressure duct 8 is connected with electric pneumatic source 3, above pedestal 1, centre position is provided with holder 5, position, the left and right sides, holder 5 upper surface is provided with magnet 6, the setting of holder 5 and magnet 6 can better fix part, on the left of pedestal 1, top position is provided with left hydraulic cylinder 12, left hydraulic cylinder 12 is fixed by bolt and pedestal 1, left hydraulic cylinder 12 right positions is provided with piston rod 7, left hydraulic cylinder 12 top position is provided with air-pressure chamber 10, tracheae 9 is provided with in air-pressure chamber 10, tracheae 9 is connected with the air-pressure duct 8 be arranged in left hydraulic cylinder 12 upper piston rod 7, barometer 11 is provided with in air-pressure chamber 10, utilize barometer as examination criteria, not only intuitively but also environmental protection again.
Barometer 11 adopts aneroid barometer, and seal head 4 adopts rubber to be made, and air-pressure chamber 10 volume is 8 cubic decimeters, and seal head 4 is provided with O-ring seal.
Embodiment: need in use to check whether barometer 11 has fault, can electric pneumatic source 3 normally work, whether left hydraulic cylinder 12 and right hydraulic cylinder 2 can work, if check that defectiveness just cannot normally employ, if check that all normally just can carry out work, to the part checked be needed to be placed on holder 5 when carrying out work, magnet 6 on holder 5 can fix part, avoid the slip of part, after fixing part, the seal head 4 bottom left hydraulic cylinder 12 and right hydraulic cylinder 2 upper piston rod 7 is utilized to be blocked at part two ends, observe the reading of barometer 11, then electric pneumatic source 3 is opened, because the air pressure that electric pneumatic source 3 can arrange release is voluntarily how many, the air pressure that electric pneumatic source 3 provides by the air-pressure duct 8 in right hydraulic cylinder 2 upper piston rod 7 through part, arrive the air-pressure duct 8 in left hydraulic cylinder 12 piston rod 7, entering air-pressure chamber 10 by tracheae 9 again acts on barometer 11, because what barometer 11 adopted is aneroid barometer, the film sylphon that aneroid barometer utilizes elastic metallic to make is as sensing element, atmospheric pressure is converted to shifting flexibly of sylphon, pointer is driven by lever and gear train, when clockwise direction deflects, pointer just indicates the variable quantity that air pressure raises, so see that whether the variable quantity of aneroid barometer pointer is equal with the release air pressure that electric pneumatic source 3 is arranged, just can know that whether the impermeability of part is qualified.
