Description
Technical field
This utility model is related to the manufacturing field of vacuum booster, more particularly to a kind of vacuum booster housing assembly
Survey air-tightness device.
Background technology
Vacuum booster is to utilize vacuum（Negative pressure）To increase the part that driver puts on power on pedal.Vacuum booster
Housing assembly includes housing, there is through hole in the middle of housing, and riveting screw is needed beside through hole, airtight requirement after riveting screw
It is high, it is therefore desirable to which that air tightness test is carried out to the housing after riveting screw, it is bubble-tight without special detection in production at present
Device.Therefore solving the above problems, it is particularly significant just seem.
Utility model content
To solve the above problems, this utility model provides a kind of survey air-tightness device of vacuum booster housing assembly, leads to
Cross the positioning round depression interior sealing that housing is buckled in into rubber slab good, it is with rubber stopper that housing seal is good, tap is inserted afterwards
Evacuation in hole in the middle of housing, then see whether be inhaled into opposite side with to dripping at riveting screw, so as to detect air-tightness,
Solve produced problem in background technology.
The purpose of this utility model is to provide a kind of survey air-tightness device of vacuum booster housing assembly, includes work
Platform, the bench-top middle setting has working plate, and working plate top arranges rubber slab；The bench-top left side is arranged
There is fix bar, through there is vacuum-pumping tube, vacuum-pumping tube right side is provided with vacuum head to fix bar, and vacuum head bottom is provided with takes out
Head is for inserting hole in the middle of housing to enclosure interior evacuation；The vacuum-pumping tube left side is connected with downwards vacuum pumping pump；Institute
State bench-top right side and side lever is set, side lever left side is connected with supporting rod, and supporting rod left side is provided with Squirting bottle for spiral shell
Sprayed water at nail；The workbench right hand top is provided with placement plate, places and rubber stopper use diversified in specifications is distributed with plate
In clogging the unnecessary hole of housing.
Further improvement is that：Sealing rubber ring is cased with outside the tap for the hole sealing in the middle of housing is dead.
Further improvement is that：The rubber slab top is provided with the positioning coincideing with vacuum booster housing assembly bottom
Circular depressed is used to that housing bottom to be sucked into good seal during evacuation.
Further improvement is that：The rubber slab top is located in positioning round depression and is provided with positioning plectane for housing
Quickly put well.
The beneficial effects of the utility model：This utility model is close in the positioning round of rubber slab depression by the way that housing is buckled in
Seal, afterwards blocked in other holes on housing with rubber stopper, afterwards tap is inserted in the hole in the middle of housing, sealing rubber ring
Hole in the middle of housing is blocked, afterwards vacuum pumping pump works to evacuation in housing, after evacuation is finished, by Squirting bottle to riveting
To connect dripped at screw and see whether be inhaled into opposite side, so as to detect air-tightness, housing air-tightness can be entered easily and fast
Row detection, it is adaptable in production.
