Description
Technical field
The utility model is related to a kind of vacuum test machine for engine cylinder cover, engine cylinder cover to belong to auto parts machinery.
Background technology
, it is necessary to be tested to engine cylinder cover in the process of manufacture of automobile engine cylinder head, in one of those
One of appearance is to carry out sealing property detection to the cavity of engine cylinder cover, because each engine cylinder cover has even number cavity,
More than quantity more than 8, be in the prior art to detect one by one, waste time and energy, inefficiency.
Utility model content
The utility model is not enough according to more than, there is provided a kind of vacuum test machine for engine cylinder cover, by multiple
Cylinder synchronization action, disposably completes the sealing property detection of all cavitys.
The technical solution of the utility model is：
A kind of vacuum test machine for engine cylinder cover, it is characterized in that, including：
Workbench, for placing and fixation engine cylinder cover to be checked；
Cylinder, quantity is identical with the cavity of engine cylinder cover, and the cylinder body of cylinder is fixed relative to workbench, and cylinder is by electromagnetism
Valve is controlled；
Silently, quantity is identical with cylinder, and silently the gangbar with cylinder is fixed, when gangbar is stretched out, silently sealed circle
It is capable of the left surface gas outlet of canned motor cylinder cap cavity and by lateral flow orifices；
Vavuum pump, connects with silently gas circuit；
Vacuum table, connects with silently gas circuit；
Valve, quantity and silently identical, each cavity for isolating engine cylinder cover, valve is by head and bar portion group
Into bar portion is arranged with tubular seals circle, and head is tapered, is arranged with O-ring seal, when valve from the top chamber of engine cylinder cover
When body inserts the air flue of engine cylinder cover, the cavity of engine cylinder cover valve, tubular seals circle, O-ring seal, silently with it is close
Seal forms annular seal space under surrounding；
During vacuum pump work, annular seal space is evacuated, vacuum table display vacuum state.
When using, left surface gas outlet will be silently covered and by lateral flow orifices by controlling magnetic valve, manually insert gas
Door, starts vavuum pump, keeps certain vacuum, and closes vavuum pump, through a period of time after, if vacuum table changes, send out
The cavity of motivation cylinder cap is possible to gas leakage, it is necessary to check whether engine cylinder cover has crack etc..
The vavuum pump is provided with two, and vacuum table is provided with two, left surface gas outlet and right flank gas outlet it is vexed
Head is respectively communicated with two vavuum pumps and two vacuum tables.Can detect and start by setting two vavuum pumps and two vacuum tables
The left side cavity and/or right side cavity of machine cylinder cap leak air, and accelerate detection speed.
The utility model has that simple structure, low cost, detection speed are fast, improve the beneficial effect of operating efficiency.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Specific embodiment
The utility model is further described in conjunction with accompanying drawing：
As illustrated, a kind of vacuum test machine for engine cylinder cover, including：
Workbench, for placing and fixation engine cylinder cover 4 to be checked；
Cylinder 1, quantity is identical with the cavity 5 of engine cylinder cover, and the cylinder body of cylinder 1 is fixed relative to workbench, cylinder 1 by
Solenoid valve control；
Silently 2, quantity is identical with cylinder 1, silently 2 is fixed with the gangbar 11 of cylinder 1, when gangbar 11 is stretched out, silently 2
Sealed circle 3 is capable of the left surface gas outlet of canned motor cylinder cap cavity and by lateral flow orifices；
Vavuum pump 8, connects with silently 2 gas circuits；
Vacuum table 7, connects with silently 2 gas circuits；
Valve 6, quantity is identical with silently 2, and valve 6 is made up of head and bar portion, and bar portion is arranged with tubular seals circle 62, head
Portion is tapered, is arranged with O-ring seal 61, when valve 6 inserts the air flue of engine cylinder cover from the top cavity of engine cylinder cover
When, the cavity 5 of engine cylinder cover valve 6, tubular seals circle 62, O-ring seal 61, silently 2 and sealing ring 3 surround under formed
Annular seal space；
When vavuum pump 8 works, annular seal space is evacuated, the display vacuum state of vacuum table 7.
Vavuum pump 8 is provided with two, and vacuum table 7 is provided with two, and silently the 2 of left surface gas outlet and right flank gas outlet
It is respectively communicated with two vavuum pumps 8 and two vacuum tables 7.
