Accompanying drawing explanation
By reading detailed description non-limiting example made with reference to the following drawings, other features, objects and advantages of the present utility model will become more apparent upon:
Fig. 1 is the structural representation of a kind of vehicle part air-tightness detection device of this utility model;
In figure: the right hydraulic cylinder of 1-pedestal, 2-, 3-electric pneumatic source, 4-seal head, 5-fixing seat, 6-Magnet, 7-piston rod, 8-air-pressure duct, 9-trachea, 10-air-pressure chamber, 11-barometer, 12-left hydraulic cylinder。
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with detailed description of the invention, this utility model is expanded on further。
Refer to Fig. 1, this utility model provides a kind of technical scheme: a kind of vehicle part air-tightness detection device, including 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 with pedestal 1 by bolt, 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 with right hydraulic cylinder 2 by bolt, right hydraulic cylinder 2 leftward position is provided with piston rod 7, seal head 4 it is provided with bottom piston rod 7, piston rod 7 is internally 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 fixing seat 5, fixing position, the left and right sides, seat 5 upper surface is provided with Magnet 6, fixing seat 5 and arranging of 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 with pedestal 1 by bolt, 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, trachea 9 it is provided with in air-pressure chamber 10, trachea 9 is connected with the air-pressure duct 8 being arranged in left hydraulic cylinder 12 upper piston rod 7, barometer 11 it is provided with in air-pressure chamber 10, utilize barometer as examination criteria, not only intuitively and 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 sealing ring。
Detailed description of the invention: need in use to check whether barometer 11 has fault, can electric pneumatic source 3 normal operation, whether left hydraulic cylinder 12 and right hydraulic cylinder 2 can work, defective just cannot normally employ if checked, just can be operated if checking to all go well, the part checked will be needed to be placed on fixing seat 5 when being operated, Magnet 6 on fixing seat 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 it is how many that electric pneumatic source 3 can arrange the air pressure of release voluntarily, the air pressure that electric pneumatic source 3 provides passes through 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, enter air-pressure chamber 10 again through trachea 9 and act on barometer 11, because what barometer 11 adopted is aneroid barometer, aneroid barometer utilizes thin film sylphon that elastic metallic makes as sensing element, atmospheric pressure is converted to shifting flexibly of sylphon, pointer is driven by lever and drive mechanism, when deflecting clockwise, pointer indicates that the variable quantity that air pressure raises, so seeing that whether the variable quantity of aneroid barometer pointer is equal with the release air pressure that electric pneumatic source 3 is arranged, just may know that whether the air-tightness of part is qualified。
