Description
Technical field
The present invention relates to detection fields, and in particular to a kind of watertightness air-tightness detection device.
Background technique
Workpiece in a kind of equipped with inner cavity is equipped with outwardly convex at the center of multiple sides of workpiece in cube-shaped
Opening, and the opening on two relative side is symmetrical, this workpiece generally passes through casting and forming.When casting, by the metal of molten state
Liquid injects mold, then cools down to mold, so that the molten metal fast cooling shaping in mold, but inhomogeneous cooling is even
When, crackle is easy to appear on workpiece, and cracked workpiece is easy gas leakage or leakage in use, so splitting
The workpiece of line belongs to substandard products.But some crackles are smaller, are visually difficult to find, so needing to carry out workpiece watertightness and airtight
Property detection.
When carrying out air-leakage test, using gripping means grips workpiece, the opening of workpiece outwardly convex is across clamping at this time
Device, opening are located at outside the cavity that clamping device is formed, and water is added in the cavity then formed to clamping device, detects workpiece
Watertightness and air-tightness.After detection, in order to reduce the water entered in workpiece lumen, need first to arrange the water in clamping device
Out, then so that clamp system is loosened workpiece again, workpiece is taken out, then carry out air-dried water on removal workpiece to workpiece.But
During taking out workpiece, the water adhered on clamp system is easy from the inner cavity that the opening of workpiece enters workpiece, removes work
When water on part, it is also necessary to the inner cavity of workpiece is carried out it is air-dried, wind-force and it is temperature-resistant in the case where, air-dry the time needed
It is longer.Secondly, first draining, air-drying again, the time needed is longer, the inefficiency of detection.
Summary of the invention
The purpose of the present invention is to provide the watertightness air-tightness inspections for avoiding water to enter workpiece lumen when a kind of taking-up workpiece
Scaffold tower blow-dry device.
In order to achieve the above objectives, the technical scheme is that a kind of watertightness airtightness test table blow-dry device, packet
Including rack, workbench air-dry mechanism and at least one closing means, workbench and are fixed on the rack, air-dried mechanism include blower,
Heating member air-dries pipe and air inlet pipe, and blower is fixed on the table, one end of air inlet pipe and air-dried pipe with the outlet side of blower
Connection air-dries pipe and is equipped with the switch that can close air-dried pipe, and heating member is fixed on the periphery of air inlet pipe and air-dried pipe；Closing means
Including air bag, pressure valve and check valve, air bag includes internal layer and the outer layer positioned at internal layer periphery, and pressure valve and check valve are fixed
Extruded on internal layer, the outlet side of check valve is connected to internal layer, and air inlet pipe can be connected to far from blower one end with the inlet end of check valve, outside
Layer is equipped with several through-holes through outer layer.
After the watertightness and air-leakage test of workpiece, extraneous opening is exposed at from workpiece, closing means are put into work
In part, then air inlet pipe being connected to far from blower one end with check valve, and open blower, blower is inflated into the internal layer of air bag,
Pressure increase, inner layer expansion, the opening of balloon occlusion workpiece in internal layer.Then air inlet pipe is removed, and by workpiece from clamping device
On remove, due to the opening of balloon occlusion workpiece, therefore during removing workpiece, clamping device and the water measured can not
Enter in the inner cavity of workpiece from the opening of workpiece.
After taking out workpiece, air inlet pipe is connected to check valve again and is opened heating member, the pressure in internal layer is greater than pressure
When the preset value of valve, the gas in internal layer enters outer layer, then blows out from through hole.The wind blown out from through hole can be to attachment
Water around at the workpiece openings is dried.Then it turns on the switch, is dried using periphery of the air-dried pipe to workpiece.Workpiece
Blower, heating member and switch, and extruding gasbag are closed after drying, the pressure of air bag internal layer increases at this time, the gas in internal layer into
Enter outer layer and be discharged from through-hole, the volume of last air bag reduces, and takes out from workpiece openings by air bag.
Before the having the beneficial effect that of this programme (one) takes out workpiece, air bag is put into workpiece by the opening of workpiece, then
Air inlet pipe is inflated into air bag, and air bag expansion can block the opening of workpiece, water can not enter in workpiece from the opening of workpiece
Portion, so not needing first to drain the water for carrying out detection around workpiece when taking out workpiece, draining can be simultaneously with taking-up workpiece
It carries out, improves detection efficiency.
(2) workpiece takes out and passes through air inlet pipe to after the inflation of the internal layer of air bag, and pressure in internal layer is more than the pre- of pressure valve
If the gas in internal layer enters outer layer when value, then blown out from through-hole, since the cavity volume of workpiece is certain, last air from
The opening of workpiece is blown out, and can carry out to the parameatal water of workpiece air-dried, avoids taking out parameatal water when air bag
Into in workpiece lumen, further avoid ponding in workpiece lumen, reduce workpiece and need air-dried position, shorten air-dry time,
It improves and air-dries efficiency.
(3) during entirely taking out workpiece and air-drying to workpiece, water all be cannot be introduced into workpiece lumen, and work
When part is cast, since there are a large amount of dusts in the air in workshop, so there is also dust in the inner cavity of workpiece, workpiece is opened at this time
Mouth closing, the dust in workpiece lumen will not be contacted with water, after without being adhered in workpiece lumen；Sky in air bag
Gas from through-hole blow out during, the dust in workpiece lumen can also be blown out, thus can simultaneously to workpiece lumen carry out
Dedusting.
(4) pressure valve can make air bag internal layer keep larger pressure, and air bag is enable to expand the opening of simultaneously closed work piece,
Air bag outer layer is located at internal layer periphery, and pressure valve is avoided directly to contact with workpiece lumen, and pressure valve is avoided to be worn and pressure valve
Gap and leak are generated between workpiece lumen.
Preferred embodiment one, is further improved as to base case, and workbench is equipped with diversion trench.In detection process or
In drainage procedure, water can flow after flowing on workbench along diversion trench, avoid workbench ponding, and testing staff is avoided to examine
Clothing is dampened during survey.
Preferred embodiment two, as the further improvement to preferred embodiment one, air inlet pipe is bellows.Bellows can be drawn
It is long, it after taking out workpiece, pulls air inlet pipe that can increase the length of air inlet pipe, guarantees that air inlet pipe has enough length and is located at workpiece
Interior check valve connection.
Preferred embodiment three, as the further improvement to preferred embodiment two, heating member is adding thermal resistance silk screen.Resistance screen
Bigger with the contact area of air inlet pipe and air-dried pipe, heating effect is more preferable.
Preferred embodiment four, as the further improvement to preferred embodiment three, bottom of the frame is equipped with several supporting cylinders, branch
Support hydraulic cylinder bottom is fixed on the rack, and is fixed with support rod on the piston of supporting cylinder.It can by adjusting supporting cylinder
To adjust the height of workbench, the testing staff for being allowed to be more suitable for different height is operated, and is improved when testing staff operates
Comfort level.
Preferred embodiment five, as the further improvement to preferred embodiment four, support rod bottom is fixed with support base.Support base
The contact area with ground can be increased, to reduce the pressure that ground is born in unit area, ground is avoided to be subject to crushing.
Preferred embodiment six, as the further improvement to preferred embodiment five, support base bottom is fixed with rubber layer.Rubber layer
It can be worn to avoid support base, extend the service life of support base.
