Embodiment
Fig. 1, Fig. 2 and Fig. 3 have shown a specific embodiment of this leakage detection equipment of the utility model, and it comprises pedestal 11, be provided with altogether two and detect station on pedestal 11, and each detection station includes with lower member:
The sealing clamp being formed by chuck body 8 and fixture lid 4, between described fixture lid 4 and chuck body 8, removable seal is connected, in the time that fixture lid 4 is sealedly connected in described chuck body 8, described sealing clamp has the closed cavity jointly being formed by described chuck body and fixture lid;
The pressure transducer of gaseous tension (the closed cavity airflow connection of pressure transducer and fixture, not shown in FIG.) in closed cavity described in Real-Time Monitoring;
Vertically be fixed on some (this example is four) guideposts 6 on described pedestal 11;
A fixture lid fixed head 3 that is connected on described four guideposts 6 and can slides up and down along guidepost, described fixture lid 4 is fixed on the bottom of described fixture lid fixed head 3;
Be fixedly connected on a master cylinder fixed head 2 of described four guidepost 6 upper ends;
Be fixed on the master cylinder 1 on described master cylinder fixed head 2, this master cylinder has the cylinder axis stretching out straight down, and described fixture lid fixed head 3 is positioned at the below of this cylinder axis;
And fill exhaust pedestal 9 and chuck body 8 airflow connections for the exhaust pedestal 9(that fills that the closed cavity of described sealing clamp is filled to pump-down process), described chuck body 8 is fixed on fills on exhaust pedestal 9, and chuck body 8 is positioned at the below of described fixture lid fixed head 3.
Each detection station is provided with two start buttons 10, only has to open these two start buttons 10 simultaneously and could start this detection station, with the personal injury that prevents that maloperation from bringing.
When use, the fixture lid fixed head 3 that first moves up makes fixture lid 4 and chuck body 8 in separated position, and the inner chamber of sealing clamp is opened.Then in fixture inner cavity, put into workpiece to be detected, press described start button 10 and make equipment in starting state.Control master cylinder 1 action its cylinder axis is stretched out downwards, thereby prop up fixture lid fixed head 3 and fixture lid 4 moves down, and allow fixture lid 4 tightly be pressed in chuck body 8, and then make in the workpiece to be detected closed cavity in sealing clamp.Then, fill exhaust pedestal 9 fixture closed cavity is vacuumized after processing, then be filled with fast a certain amount of pressure gas, stop inflation, pressure transducer is responded to and is demonstrated the gas pressure value (being referred to as original pressure value) in closed cavity now.After a period of time, (set as required the occurrence of this time period), again read the gas pressure value of described pressure transducer demonstration and itself and aforementioned original pressure value are relatively asked to poor, draw the front and back difference of gaseous tension in closed cavity.If this difference exceedes setting value (this setting value need to be determined according to client), explanation institute's workpiece that detects exists leakage obvious, belongs to defective; If this difference is zero or is less than setting value, illustrate that workpiece does not have leakage problem completely or leaks in tolerance interval, belongs to certified products.
As depicted in figs. 1 and 2, when allowing described fixture lid 4 and chuck body 8 fasten, the two can accurately be aimed at, and this example is fixed with the register pin 5 stretching out straight down on fixture lid 4, and in chuck body 8, is shaped with the pilot hole corresponding with described register pin 5 (not marking in figure).And four guideposts 6 also play correcting effect to moving up and down of fixture 4, avoid fixture lid 4 to be offset in the time that chuck body 8 moves.
As shown in figures 1 and 3, this example on described pedestal 11, be also fixed with two horizontally disposed, for described clamp cap 4 being locked to the fixing cylinder 7 of fixture in chuck body 8.When work, after master cylinder 1 is pressed in chuck body 8 by fixture lid 4, controls the fixing cylinder 7 of these two fixtures and move, so that fixture lid 4 is further locked in chuck body 8, guarantee the sealing of sealing fixture.In chuck body 8, be fixed with the sealing strip between chuck body and fixture lid, sealing strip can further guarantee the sealing between chuck body 8 and fixture lid 4.
As shown in Figure 1, for the ease of movement and the location of this setting position, this example is also provided with castor 12 and adjustable for height heel brace 13 in the bottom of described pedestal 1.
Certainly, above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow people can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations doing according to the Spirit Essence of the utility model main technical schemes or modification, within all should being encompassed in protection domain of the present utility model.
