Description
Technical field
The invention belongs to automobile technical field, refer to a kind of airtight testing fixture especially, especially a kind of barrel type airtight machine for wheel hub.
Background technology
Wheel of the bus is made up of wheel hub and tire, which support the weight of full car, makes automobile be able to travel on road, has significant impact to automobilism performance.Wheel hub is the important component part of automobile, and tire itself is software, in tire wide support tire drum-shaped, center is contained in parts on axle to be just wheel hub.Existing wheel hub is cast or is welded, sand holes may be there are in casting process, but be with the naked eye difficult to find out, if do not do air-leakage test, if so have sand holes, gas leakage is just easy to after loading onto tire, if automobile is being run at high speed, just there is potential safety hazard, it is related to the security performance of whole vehicle, therefore in wheel hub manufacture process, sealing propertytest should be carried out to automobile steel wheel hub weld seam, to determine that this product weld seam in the manufacturing whether exists the phenomenon of leakage, guarantee the doughnut in use not generation accident because of the leakage of wheel hub.In addition, wearing and tearing or the hub bearing damaged or hub can make vehicle, in the road travelled, the inefficacy of higher cost occur.Obviously, the airtight detection of wheel hub is just seemed extremely important, and current detection method is visual bubble method, are soaked by entirety after the whole wheel rim of polyurethane sheet press seal of area the same as wheel rim and lead to 0.6Mpa gas in wheel rim two ends and enter airtight cavity, observation has bubble-free on the water surface, the equipment of this kind of method is heavy, huge cost is high, precision and efficiency of detecting is low, human factor impact is large, also humidity can be brought to get rusty the harmful effects such as impurity immersion and loaded down with trivial details surface of test piece attached water (or oil) aftertreatment to workpiece simultaneously.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose energy consumption and only use original per mille, greatly save the energy, effectively can detect that weld leakage point guarantees that the wheel hub produced is air tight, and occupation area of equipment is little, the efficiency of detection exceeds the barrel type airtight machine for wheel hub of many times than classic method.
For achieving the above object, present invention employs following technical proposal: a kind of barrel type airtight machine for wheel hub, it is characterized in that, comprise the underframe of bottom with hydraulic system, this underframe upper surface is provided with the base plate be connected with regulator cubicle, described base plate is provided with two groups of hydraulic corner oil cylinders, described hydraulic corner oil cylinder of often organizing is respectively equipped with several oil cylinders arranged side by side, the output terminal of each hydraulic corner oil cylinder is provided with and can compresses holding down assembly of wheel hub, back-up block is provided with between these two groups of hydraulic corner oil cylinders, this back-up block is provided with and can forms the seal of sealed cavity with hub surface, and the bottom of the seal is provided with the through hole that can inflate.
In above-mentioned a kind of barrel type airtight machine for wheel hub, described holding down assembly comprises the pressing plate on the output terminal being hinged on hydraulic corner oil cylinder, and described pressing plate end is provided with perpendicular downward briquetting.
In above-mentioned a kind of barrel type airtight machine for wheel hub, described seal concavity, centre is provided with groove, and described through hole is arranged on groove bottom.
In above-mentioned a kind of barrel type airtight machine for wheel hub, described regulator cubicle is arranged on tray side.
In above-mentioned a kind of barrel type airtight machine for wheel hub, the described oil cylinder often organizing hydraulic corner oil cylinder is provided with two.
In above-mentioned a kind of barrel type airtight machine for wheel hub, described underframe is connected with base plate by lifting bolt.
In above-mentioned a kind of barrel type airtight machine for wheel hub, the bottom of described underframe is provided with adjusting bolt.
Compared with prior art, the invention has the advantages that: this equipment is simple, the precision detecting leakage point is high, effectively can find leakage point, ensure that the safe handling of wheel hub.And wheel hub is without the need to contacting with water (or oil), prevent water (or oil) to wheel hub cause get rusty, the harmful effect such as contaminating impurity, the aftertreatment simultaneously also need not carried out hub surface attached water (or oil), saves the time.The efficiency detected is high, compares traditional detection efficiency and exceeds 20 times more than.Equipment volume is little, can not take too large area, does not affect other work.Energy consumption in testing process also only has the per mille of former method, saves the energy.This detection method structure is simple, easy to detect, and fast, clean, accurately, cost is low, effectively can detect whether wheel hub exists leakage, ensure that the doughnut in use not generation accident because of the leakage of wheel hub.
